Chemistry Method Uses 'Test Tubes' Far Smaller than the Width of a Hair

 

Newswise — Using a water droplet 1 trillion times smaller than a liter of club soda as a sort of nanoscale test tube, a University of Washington scientist is conducting chemical analysis and experimentation at unprecedented tiny scales.

The method captures a single cell, or even a small subcellular structure called an organelle, within a droplet. It then employs a powerful laser microscope to study the contents and examine chemical processes, and a laser beam is used to manipulate the cell or even just a few molecules, combining them with other molecules to form new substances.

This nanoscale "laboratory" is so minuscule that it covers just 1 percent of the width of a human hair, said Daniel Chiu, a UW associate chemistry professor who is developing the unique method.

Gold bowties may shed light on molecules and other nano-sized objects

 

One of the great challenges in the field of nanotechnology is optical imaging-specifically, how to design a microscope that produces high-resolution images of the nano-sized objects that researchers are trying to study. For example, a typical DNA molecule is only about three nanometers wide-so tiny that the contours of its surface are obscured by light waves, which are hundreds of nanometers long.

Now, researchers from Stanford University have greatly improved the optical mismatch between nanoscale objects and light by creating the ``bowtie nanoantenna,`` a device 400 times smaller than the width of a human hair that can compress ordinary light waves into an intense optical spot only 20 nanometers wide. These miniature spotlights may one day allow researchers to produce the first detailed images of proteins, DNA molecules and synthetic nano-objects, such carbon nanotube bundles.

``One of our goals is to build a microscope with bowtie antennas that we can scan over a single molecule,`` says W.E. Moerner, the Harry S. Mosher Professor of Chemistry at Stanford...read the wave

Nanotechnology Presents Possibility of Implantable Artificial Kidney

 

Researchers have developed a human nephron filter (HNF) that would eventually make possible a continuously functioning, wearable or implantable artificial kidney. This study is published in the latest issue of Hemodialysis International.

The HNF is the first application in developing a renal replacement therapy (RRT) to potentially eliminate the need for dialysis or kidney transplantation in end-stage renal disease patients. The HNF utilizes a unique membrane system created through applied nanotechnology. In the ideal RRT device, this technology would be used to mimic the function of natural kidneys, continuously operating, and based on individual patient needs.

No dialysis solution would be used in the device. Operating 12 hours a day, seven days a week, the filtration rate of the HNF is double that of conventional hemodialysis administered three times a week.

“The HNF system, by eliminating dialysate and utilizing a novel membrane system, represents a breakthrough in renal replacement therapy based on the functioning of native kidneys,” say researchers. “The enhanced solute removal and wearable design should substantially improve patient outcomes and quality of life.” ..read the wave

Solaris Nanosciences Demonstrates the World's First Rechargeable Long-Life Solar Cell

 

PROVIDENCE, R.I., /PRNewswire/ -- Solaris Nanosciences has demonstrated a completely rechargeable dye sensitized solar cell (DSSC or Graetzel Cell) creating the lowest manufacturing cost, long-life photovoltaic system in the world. DSSCs which are based on low cost materials and simple construction, have to date suffered from limited operating lifetimes due to the degradation of the sensitizer dyes.

Solaris' nontoxic chemical process allows the degraded dye in already installed DSSCs to be removed and replaced with new dye, restoring the performance of the original solar cell. "This low cost process, which can be performed by the existing base of heating and air conditioning businesses, requires less than thirty minutes and takes the operating life of these photovoltaics (PV) beyond that of silicon to over 30 years," said Nabil M. Lawandy, CEO of Solaris Nanosciences. Lawandy also stated, "Not only can we replace the original dye, but we have shown that newer, more efficient dyes, resulting from ongoing efforts worldwide, can be used in recharging. This effectively allows for efficiency upgrades over the life of the installed system." ...read the wave

Virginia Tech researcher reports nano-particle dispersion technique improves polymers

 

Blacksburg, VA --- There is a lot of excitement about incorporating nano particles into polymers because of the ability to improve various properties with only a small percent of the particles. "You can improve the barrier to gases, such as hydrogen, carbon dioxide, and oxygen. You can increase material strength with little increase in weight," said Don Baird, professor of chemical engineering at Virginia Tech.

But there are problems. "While 1 percent by weight of nano particles will change a material's properties dramatically, 2 or 3 percent provides hardly any additional enhancement," he said. "The particles just clump together, and thereby reduce the advantages associated with the surface area of single particles."

Another problem is that the incorporation of nano particles changes a polymer's flow properties leading to potential processing problems

Nano Machines Take Giant Leap

 

A key technological breakthrough led by the University of Edinburgh suggests that a futuristic world where people can move objects about “remotely” with laser pointers could be closer than we think. Chemists working on the nanoscale (80,000 times smaller than a hair's breadth) have managed to move a tiny droplet of liquid across a surface - and even up a slope - by transporting it along a layer of light-sensitive molecules.

Scientists at Edinburgh, Groningen and Bologna are the first to manipulate tiny nanoscale machines (two millionths of a millimetre high) so that they can move an object that is visible to the naked eye. The team has shifted microlitre drops of diiodomethane not just across a flat surface, but also up a one millimetre, 12 degree slope against the force of gravity. It may be the tiniest of movements, but, in the emerging discipline of nanotechnology, it represents a giant technological leap forward...read the wave

Tiny rubber balls give plastic bounce

 

Automobile bumpers that deform and recover rather than crack and splinter, computer cases that withstand the occasional rough encounter, and resilient coatings that can withstand the ravages of the sun, may all be possible if tiny functionalized rubbery particles are imbedded in their plastic matrices, according to Penn State materials scientists.

"Plastics such as polypropylene, nylon, polycarbonate, epoxy resins and other compounds are brittle and fracture easily," says Dr. T.C. Chung, professor of materials science and engineering. "Usually, manufacturers take rubbery compounds and just mix them with the plastic, but there are many issues with this approach."

The problems include difficulty in controlling the mixing of the two components and adhesion between the plastic and rubber. Chung, and Dr. Usama F.

Nanocoating Could Eliminate Foggy Windows and Lenses

 

Newswise — Foggy windows and lenses are a nuisance, and in the case of automobile windows, can pose a driving hazard. Now, a group of scientists at the Massachusetts Institute of Technology (MIT) may have found a permanent solution to the problem. The team has developed a unique polymer coating — made of silica nanoparticles — that they say can create surfaces that never fog.

The transparent coating can be applied to eyeglasses, camera lenses, ski goggles … even bathroom mirrors, they say. The new coating was described today at the 230th national meeting of the American Chemical Society, the world's largest scientific society.

Researchers have been developing anti-fog technology for years, but each approach has its drawbacks. Some stores carry special anti-fog sprays that help reduce fogging on the inside of car windows, but the sprays must be constantly reapplied to remain effective. Glass containing titanium dioxide also shows promise for reduced fogging, but the method only works in the presence of ultraviolet (UV) light, researchers say...read the wave

Brookhaven's "Electro Pen" may impact a host of developing nanotechnologies

 

Upton, NY, At the U.S. Department of Energy's Brookhaven National Laboratory, scientists have developed a new chemical "writing" technique that can create lines of "ink" only a few tens of nanometers, or billionths of a meter, in width.

"Our new 'writing' method opens up many new possibilities for creating nanoscale patterns and features on surfaces. This may have a significant impact on developing nanotechnologies that involve nanopatterning, such as molecular electronics -- tiny circuits built using single organic molecules," said Brookhaven Lab physicist Yuguang Cai. Cai will discuss the method at the 230th American Chemical Society national meeting in Washington, D.C., on Sunday, August 28, at 12 p.m. in room 8-9 of the Renaissance Hotel.

Cai and his colleagues call the technique "Electro Pen Nanolithography" (EPN). They sweep a very thin metal tip across a film of organic molecules. The tip carries an electric voltage, which causes the region under it to "oxidize," or undergo a reaction that changes the chemical makeup of the film. In a single sweep of the pen, organic "ink" molecules are transferred from the tip to the oxidized regions, creating an extremely thin line.

Self-Assembled DNA Buckyballs for Drug Delivery

 

Newswise — DNA isn't just for storing genetic codes any more. Since DNA can polymerize -- linking many molecules together into larger structures -- scientists have been using it as a nanoscale building material, constructing geometric shapes and even working mechanical devices.

Now Cornell University researchers have made DNA buckyballs -- tiny geodesic spheres that could be used for drug delivery and as containers for chemical reactions.

The term "buckyballs" has been used up to now for tiny spherical assemblies of carbon atoms known as Buckminsterfullerenes or just fullerenes. Under the right conditions, carbon atoms can link up into hexagons and pentagons, which in turn assemble into spherical shapes (technically truncated icosahedrons) resembling the geodesic domes designed by the architect-engineer Buckminster Fuller. Instead of carbon, the Cornell researchers are making buckyballs out of a specially prepared, branched DNA-polystyrene hybrid. The hybrid molecules spontaneously self-assemble into hollow balls about 400 nanometers (nm) in diameter. The DNA/polystyrene "rods" forming the structure are each about 15 nm long. (While still on the nanoscale, the DNA spheres are much larger than carbon buckyballs, which are typically around 7 nm in diameter.)...read the wave

Location of Crucial Atoms in Superconductors

 

Newswise — With an advanced imaging technique and a savvy strategy, researchers at Cornell University's Laboratory of Atomic and Solid State Physics (LAASP) have shown how adding charge-carrying atoms like oxygen to a superconductor can increase the material's ability to conduct electricity overall and -- paradoxically -- to decrease it in localized spots.

The discovery, published in the Aug. 12 issue of Science , could lead to the eventual development of more effective superconductors.

The scientists, led by Cornell professor of physics J.C. Séamus Davis, used a specialized scanning tunneling microscope (STM) in the basement of Cornell's Clark Hall for the research. They identified for the first time the locations of individual oxygen atoms within a particular superconductor's molecular structure and used that information to examine how the atoms affect current flow in their immediate vicinity. It's a small but vital step, they say, toward understanding how superconductors work.

PROVING DA VINCI RIGHT AT THE ATOMIC SCALE

 

AMES, Iowa – A genius well ahead of his time, Leonardo Da Vinci continues to inspire even 500 years after his remarkable life. His works are central to the best selling mystery novel The Da Vinci Code and its upcoming film adaptation, and his theories on friction are helping a group of scientists from the U.S. Department of Energy's Ames Laboratory and Lawrence Berkeley National Laboratory unlock the mystery of friction at the molecular level.

In a nutshell, Da Vinci proposed that if two contacting surfaces are geometrically similar, – commensurable – they will have a much higher coefficient of friction than two geometrically dissimilar surfaces, due to the fact that the similar surfaces have a tendency to interlock. To test this theory at the molecular level, the research team looked at a quasicrystalline material that exhibits both periodic and aperiodic configurations in its crystal structure. What they found, in results to be published in the August 26 issue of the journal Science, was that friction along the periodic surface was about eight times greater than the friction along the aperiodic axis...read the wave

Chemical Could Revolutionize Polymer Fuel Cells

 

Atlanta — Heat has always been a problem for fuel cells. There's usually either too much (ceramic fuel cells) for certain portable uses, such as automobiles or electronics, or too little (polymer fuel cells) to be efficient.

While polymer electrolyte membrane (PEM) fuel cells are widely considered the most promising fuel cells for portable use, their low operating temperature and consequent low efficiency have blocked their jump from promising technology to practical technology.

But researchers at the Georgia Institute of Technology have pinpointed a chemical that could allow PEM fuel cells to operate at a much higher temperature without moisture, potentially meaning that polymer fuel cells could be made much more cheaply than ever before and finally run at temperatures high enough to make them practical for use in cars and small electronics..

Novel lipoplex nanoparticle to be used in 1st human trial treating advanced solid cancer

 

Washington D.C. -- The first clinical trial of a biologic nanoparticle designed to give back to cancer patients the tumor-busting gene they have lost is expected to start in September at Georgetown University Medical Center.

The phase I clinical study will enroll 20 patients with advanced solid cancers (including most common tumor types), and is the culmination of more than a decade of work by a team of researchers led by Professor Esther H. Chang, Ph.D. at the Lombardi Comprehensive Cancer Center.

Their research has led to development of a tiny structure -- measuring a millionth of an inch across -- that resembles a virus particle that can penetrate deeply into the tumor and move efficiently into cells. The device is a "liposome" -- a microscopic globule made of lipids -- that is spiked on the outside with antibody molecules that will seek out, bind to, and then enter cancer cells including metastases wherever they hide in the body. These molecules bind to the receptor for transferrin that is present in high numbers on cancer cells.

High NA Lenses (SIL) for Optical Data Storage Made of Synthetic Single Crystal Diamond

 

CUIJK, The Netherlands, /PRNewswire/ -- At the heart of the increase in the density of data storage is the ability to produce small lenses that operate at short wavelengths. These Solid-Immersion Lenses (SILs) conform to tight tolerances on diameter, thickness, surface form and roughness at a diameter of 1.0mm or smaller. Element Six announces the development of a process that can obtain the required form accuracy in 1mm Synthetic Single Crystal Diamond spheres. This new process has improved the accuracy of the lenses by a factor 10 compared to earlier techniques.

Since the introduction of the compact disk in 1985, it has become the standard storage medium for music, digital photography, computer data and games. As the demand for disk capacity increases, future generations of optical media will need significantly higher storage capacities. This trend is seen in DVD and its successor the Blu-Ray disk.

Nanomaterials to Mimic Cells

 

Mimicking a real living cell by combining artificial membranes and nanomaterials in one construction is the aim of a new research grant at UC Davis. The Nanoscale Integrated Research Team grant, funded by the National Science Foundation with $1.6 million over four years, will study membranes mounted on aerogels, solid materials riddled with so many tiny pores that they are mostly empty.

All living cells are wrapped in a double-layered membrane of oily lipid molecules. Cell membranes are studded with proteins and other molecules, governing how food and wastes get in and out of a cell, how cells signal to and react to their environment, and how they divide and grow.

Currently, researchers studying artificial membranes mount them on solid substrates such as gold, glass or polymers, but that means that only one side of the membrane is accessible, said Subhash Risbud, professor of chemical engineering and materials science at UC Davis and principal investigator on the project..

According to the President, the federal government has invested in projects of technological innovation, unlike what went on during the decade of the '90's, "when government research funds were cut and there was an intense denationalization of the country's industry." As examples of what the current Administration is doing, he cited the university reform and the creation of 32 university extension units in the country's poorest regions.

"We are doing this to give Brazil the necessary instruments for us to compete in the knowledge sphere on a truly equal basis with other countries that are of the same size and importance as Brazil," he emphasized.

The National Nanotechnology Program is intended to manufacture products to strengthen the country's scientific research capacity. US$ 29.81 million (R$ 71 million) will be invested this year. According to the Ministry of Science and Technology, these funds will be used to finance the projects of young scientists and the implantation of major laboratories.

Biocide-free antifouling coatings thanks to nanostructured surfaces

 

The EU research project “AMBIO” is investigating how to prevent the buildup of organisms on surfaces under marine conditions, for example on ships' hulls. Scientists from BASF are collaborating on this project with 30 partners from business and science from 14 countries. The five-year project was launched in March 2005, and involves a total budget of €17.9 million, of which €11.9 million will be provided by the European Union. The goal of the AMBIO project (Advanced Nanostructured Surfaces for the Control of Biofouling) is to use nanostructuring to significantly reduce the adhesion of organisms to surfaces in aquatic environments, and thus control the fouling process without the use of biocides.

Biofouling is an issue with both environmental and economic relevance. For example, ships with fouled hulls require 40 percent more fossil fuel to travel at the same speed as unfouled vessels. This significantly increases emissions of CO2 and other greenhouse gases. The current state of the art is to use controversial biocides such as copper and organotin compounds that prevent fouling by killing the organisms. Further examples of situations where biofouling may be a problem are.

NEW ANALYTICAL TOOL HELPS DETECT CANCER

 

AMES, Iowa -- Scientists have long used ultra-fine glass tubes known as capillaries to analyze the chemical makeup of substances. Called capillary electrophoresis, or CE, the method applies high voltage to the capillaries, and by measuring the rate that the various materials move through the capillaries, researchers are able to identify individual compounds.

A group of researchers at the U.S. Department of Energy's Ames Laboratory have developed a method called dynamic multiple equilibrium gradients, DMEG for short, that dramatically fine-tunes the process, allowing for a significant increase in resolution over previous methods. Potential applications include chemical, biological and biomedical sciences, as well as in environmental monitoring, biological warfare detection, drug discovery, and more.

“This method is hyperselective and we can design it to target specific analytes for separation,” said Ryszard Jankowiak, an Ames Lab senior scientist. “Running multiple electric field gradients can focus and move the analytes to the detection window at precisely defined times, creating signature ‘fingerprints', which minimizes the probability of false positives.”...read the wave

MU Researchers Develop New Source of Energy Using Nanotechnology

 

COLUMBIA, Mo. -- Countries across the world continue to search for new ways to create energy. As our current means for energy continue to deplete, thus making them more expensive to generate, governments are searching for new energy resources. Researchers at the University of Missouri-Columbia have developed a more efficient source of energy involving nano-scale particles that take only microseconds to create and can be developed on a surface as small as a microchip.

"This technology is considerably less expensive than existing chemical and physical processes," said Shubhra Gangopadhyay, professor of electrical engineering at MU. "It creates high amounts of mechanical and thermal energy and can convert that energy into electrical energy. So, the possibilities are endless in terms of what this energy can do."

The energy is developed using solid state energetic material consisting of fuel and oxidizer. The nano-engineered energetic material generates a tremendous amount of thermal and mechanical energy when ignited. Electric power is generated using the thermoelectric effect. The microfabricated devices coated with the energetic material are capable of producing tens of joules, which are units of energy, in the fraction of a second, which can be used for pulsed power applications or can be stored in charge storage devices for later use in portable electronics...read the wave

UC Berkeley-led research finds way to use dirty silicon, could pave way for cheaper solar energy

 

Berkeley, CA, --- A research team led by engineers at the University of California, Berkeley, has developed a new technique to handle metal defects in low-grade silicon, an advance that could dramatically reduce the cost of solar cells.

Nearly 90 percent of solar, or photovoltaic, cells in the world are made from a refined, highly purified form of silicon, the same material used to make integrated circuits. The growth of the semiconductor and solar cell industries has put increasing pressure on relatively limited supplies of this high-quality silicon, consequently driving up the price of the material.

Attempts to use the far more abundant and cheaper form of silicon - one that is laden with metal impurities and defects - have failed because solar cells made from this material do not perform as well. In addition, manufacturing techniques used to remove impurities are expensive, negating the cost benefits of using the cheaper material....read the wave

New technology developed at Northwestern University has the potential for broad application in the detection of terrorist activities such as missile attacks on U.S. troops. Scientists at the Center for Quantum Devices (CQD) have demonstrated, for the first time, uncooled infrared imaging using type-II superlattice technology. This significant development could lead to smaller, faster and less expensive hand-held infrared imaging devices.

High-speed infrared (IR) imagers are capable of sensing thermal profiles of missiles and other objects that emit heat above that of the background. These devices also have potential in medical applications where excessive heating or cooling in the body can indicate trouble, such as inflammation, circulation issues or even cancerous tissue.

“For most practical applications, high-speed operation with handheld portability is especially important,” said CQD director Manijeh Razeghi, who led the research team. “Uncooled imagers are capable of handheld operation, which is critical in situations with soldiers on the battlefield or with firefighters in a smoke-filled environment. Cooled sensors, on the other hand, typically utilize liquid nitrogen for cooling to minus 200 degrees Celsius, making the sensors expensive and bulky.” ...read the wave

Plugging the leaks in a quantum computer

 

New work by two researchers at HP Laboratories Bristol sets out to solve one of the major difficulties in quantum computer architectures that use directly interacting qubits.

The problem is that the million-or-so qubits necessary to do useful calculations in a quantum computer would all feel the presence of each other, meaning that the information would leak in an uncontrollable way. The more qubits that are put together this way, the harder it is to control them.

The solution put forward by Dr Sean Barrett and Dr Pieter Kok, working at HP Laboratories Bristol, is to put every qubits in its own box, so that they cannot directly talk to each other. However, for quantum computing to work, there does need to be some interaction between qubits so that they can become entangled. In the HP Labs system this is achieved by using the fact that every qubit can emit light particles (photons).

Quantum computing is expected to be much more powerful than conventional information processing. It should be able to search faster and simulate better, factor large numbers efficiently and virtually guarantee secure communications. The technology might still be several decades away from practical implementation

'Gadonanotubes' greatly outperform existing MRI contrast agents

 

HOUSTON, -- Researchers at Rice University, the Baylor College of Medicine, the University of Houston and the Ecole Polytechnique Fédérale de Lausanne in Switzerland have created a new class of magnetic resonance imaging (MRI) contrast agents that are at least 40 times more effective than the best in clinical use.

The new agents -- dubbed gadonanotubes -- use the same highly toxic metal, gadolinium, that is given to more than a quarter of MRI patients today, but the metal atoms are encased inside a hollow tube of pure carbon called a nanotube. Shrouding the toxic metals inside the benign carbon is expected to significantly reduce or eliminate the metal's toxicity.

The research was published this month in the journal Chemical Communications.

"In prior work, we have boosted the effectiveness of gadolinium MRI contrast agents by encasing them in spheres of carbon called buckyballs," said lead author Lon Wilson, professor of chemistry at Rice. "Each nanotube will hold more gadolinium atoms than a buckyball, so we expected them to be more effective agents. But they are actually much, much better than we anticipated, so much so that no existing theory can explain how they work." ...read the wave

Ecology Coatings Develops Cost-Effective Process for Producing Mildew-Resistant Waterproof Paper

 

Akron, Ohio (PRWEB) -- Ecology Coatings, Inc., a leading provider of nano-engineered ultraviolet curable coatings, has announced that it has used its proprietary coating technology to develop a cost-effective process for producing waterproof, mildew resistant paper. The process impregnates ordinary paper with Ecology Coatings' nanoparticle technology, maintaining the original performance properties of the paper even after being fully immersed in water. Unlike conventional waterproofing techniques involving vinyl coatings, polypropylene or other synthetic papers, Ecology Coatings' method produces waterproof, wood pulp-based paper that can be used with pencil as well as a variety of inks.

Replacing the existing method of using compressed polypropylene fibers to coat paper, Ecology Coating's nanoparticle imbuing process cuts waterproof paper production costs by 500 percent. The paper also inhibits the growth of mildew, adding further protective value to the Ecology Coatings paper. Ideal for outdoor use, packaging labels, and other paper applications at risk of damage, the coating technique maintains the paper's original writable performance without the highly slick surface typical of the waterproof paper currently available to the market

Nanotechnology to provide portable genetic risk detection

 

A state-of-the-art portable biosensing device based on micro- and nanotechnologies will empower doctors to rapidly and accurately forewarn patients of their genetic risk of developing diseases such as cancer.

Currently being developed by the IST project OPTONANOGEN, a prototype of the system will initially be used to detect mutations of the BRCA1 gene that are responsible for between 2.5 and 5 per cent of the incidence of breast cancer in women. The final system, however, could be used to detect virtually any genetic anomaly as well as proteins linked to viruses, chemical contamination in food or water pollution.

“There are a broad variety of applications for this system, although the main market is in biomedicine,” explains OPTONANOGEN coordinator Laura Lechuga at the National Microelectronics Centre (CNM) in Spain. “Though commercial biosensing systems exist they are larger and designed to be used in laboratories. We are the first to develop a fully integrated system on a small scale in this field.”

FOM en Carl Zeiss samen in onderzoek voor chipindustrie

 

De Stichting FOM en optiekspecialist Carl Zeiss SMT AG gaan een gezamenlijk onderzoekprogramma uitvoeren naar een nieuw type optiek voor het schrijven van structuren voor computerchips. Deze optiek moet rond 2009 klaar zijn voor gebruik. Carl Zeiss draagt een bedrag van 5 miljoen euro aan het onderzoekprogramma bij; FOM betaalt er 2,5 miljoen euro aan. Het onderzoek moet leiden tot spiegels waarmee licht met een golflengte van 13,5 nanometer (extreem ultraviolet) gebruikt kan worden om kleinere structuren op chips te schrijven dan met de huidige optische technieken mogelijk is.

Bij de productie van computerchips wordt het patroon van de chip op een plak silicium afgebeeld; dat gebeurt in zogeheten wafersteppers. De grootte van de details die afgebeeld kunnen worden, wordt beperkt door de golflengte van het gebruikte licht. Zichtbaar licht is tot een golflengte van ongeveer 300 nanometer bruikbaar; bij kleinere golflengte werkt gewone optiek niet meer. Zowel de lichtbronnen als de spiegels en lenzen voor zichtbaar licht zijn tot in de perfectie ontwikkeld.

FP6 project TUNAMOS uses magnetic nano-oscillator to solve limitations of integrated oscillators in wireless devices

 

Leuven, Belgium, --- The project "TUnable NAno-Magnetic OScillators for integrated transceiver applications" aims at demonstrating the breakthrough concept spin torque in a nano-scale microwave integrated oscillator for application in wireless integrated devices. The project is part of the FP6 program of the EU and is being coordinated by IMEC. Other partners in the TUNAMOS-project are STMicroelectronics, UPS Université Paris Sud and UFSD University of Sheffield. The project was launched on 1st of June 2005 for a duration of 3 years.

The recent discovery of the spin torque oscillator, a nano-patterned ferromagnetic device in which high-quality tunable microwave oscillations can be generated by a small DC current, opens perspectives to solve the paradigms in microwave engineering design. None of the RF oscillators existing today combines a high-quality resonance with a high integration level, necessary for low-power and low-cost applications, and wideband tunability.

The frequency of the oscillation generated by the spin torque oscillator can be tuned by a magnetic field as well as by the current in a range of 5- 40GHz. Quality factors as high as 18000 have been observed, making the magnetic flute a natural current-controlled RF source. This electronic device is extremely suitable for integration because of the nano-scale dimensions (diameter of the contact < 100 nm) and the simple structure of the metallic magnetic multi-layer. The fabrication is compatible with the back-end flow of standard Si technology and can fully profit from the cost/scalability economics reflected by Moore's law...read the wave

But as manufacturers have relentlessly reduced the size of transistors in order to squeeze more of them on chips, locating dopants has become progressively difficult

'Smart' nanoprobes light up disease

 

Researchers from Rice University's Center for Biological and Environmental Nanotechnology (CBEN) have developed a "smart" beacon hundreds of times smaller than a human cell that is programmed to light up only when activated by specific proteases. Altered expression of particular proteases is a common hallmark of cancer, atherosclerosis, and many other diseases.

In the September issue of the journal Biochemical and Biophysical Research Communications , lead authors Jennifer West, the Isabel C. Cameron Professor of Bioengineering and director of CBEN's biological research program, and Rebekah Drezek, the Stanley C. Moore Assistant Professor of Bioengineering and assistant professor of electrical and computer engineering, describe development of a new nanoprobe for visualization of proteolytic activity in vivo.

"The idea is to develop a 'smart' nanostructure that is dark in its original state but lights up very brightly in the presence of enzymatic activity associated with a particular disease process," said West. "Other groups have used targeted nanostructures including quantum dots for molecular imaging, but they have never been able to adequately solve the problem of clearly distinguishing between the 'cancer is here' signal and the background light which arises from nanostructures not specifically bound to their molecular targets."...read the wave

Penn Researchers Take a Big Step Forward in Making Smaller Circuits

 

PHILADELPHIA --  Physicists at the University of Pennsylvania have overcome a major hurdle in the race to create nanotube-based electronics.  In an article in the August issue of the journal Nature Materials, available online now, the researchers describe their method of using nanotubes tiny tubes entirely composed of carbon atoms -- to create a functional electronic circuit.  Their method creates circuits by dipping semiconductor chips into liquid suspensions of carbon nanotubes, rather than growing the nanotubes directly on the circuit.

"Given their amazing electric properties, nanotubes have been a subject of keen interest for creating such things as chemical sensors, flexible electronics and high-speed, high-device-density microprocessors for computing," said Alan T. Johnson, associate professor in Penn's Department of Physics and Astronomy.   "The problem is that the properties we like best about nanotubes their size and physical properties also make them very difficult to manipulate."...read the wave

 

 

Nano Debate : Global

Special Report - NanoGeoPolitics:
ETC Group Surveys the Political Landscape

 

Fearful that nanotech may face the same fate as biotech crops, the G8 used their Gleneagles summit to promote "new technologies" (including nanotech and biotech) as the magic bullet to "make poverty history" and to neutralize global warming. By hinting at the availability of billions for science capacity-building in the South, the North hopes to make allies of South governments, scientists, development NGOs, and environmentalists. Meanwhile, the real action is behind the scenes where various government/industry and scientific institutions are rushing to negotiate what the EU hopes will become a nanotech "code of conduct"(but, in light of US opposition may turn into a "framework of shared principles") and lay down the global standards, regulations, and market modus operandi for the greatest industrial revolution society has ever (not) seen coming. Social policy is being replaced by science policy. In this special report, ETC Group reviews the emerging nanogeopolitics landscape...read the wave

Single molecule is in driver's seat of molecular machine

 

EVANSTON, Ill. --- While the human body has plenty of specialized molecular motors and machines powering the mechanical work necessary for cells to function properly, scientists themselves face many hurdles as they try to create their own molecular machines in the laboratory.

The downsides of conventional molecular machines are that they are driven as an ensemble, by external light or chemistry, for example, and they are big -- made up of many molecules. These factors make these machines difficult to control.

In a theoretical paper published in the journal Physical Review Letters, two Northwestern University chemists have shown how molecular machines can be driven individually (relying on only one molecule) by applying an electric current that creates an internal energy source.

"People envision using molecular machines for computing techniques, sensors, bioengineering and solar cells, for example," said Tamar Seideman, professor of chemistry, who led the research team. "Molecular machines have unique...read the wave

Atomic force microscopy : How cell membranes respond to their environment

 

Some 25% of genes code for membrane proteins. Yet membrane organization remains a mystery. Membranes envelop all the cells in our bodies, forming a natural barrier, the membrane proteins within these can also recognize certain cells and direct a drug to them.

Using atomic force microscopy, Simon Scheuring (Inserm), in a CNRS unit at the Institut Curie, and James N. Sturgis, professor at the Université de la Méditerranée (CNRS unit), have studied the organization of a bacterial membrane and how it adapts in response to external factors. This is the first time that the inner workings of a membrane have been unveiled. Scheuring and Sturgis show that the organization of membrane proteins is not fixed but can vary with membrane location and time. This work was published in the July 15, 2005 issue of Science...read the wave

Italian research opens door to new hydrogen production method

 

Researchers in Italy have developed a new technique for producing hydrogen, and for purifying polluted gases.

The technique involves the release of oxygen from cerium oxide, a pale yellow-white powder used in ceramics and to polish glass.

'Ceria-based materials are oxygen buffers, materials that allow [one] to efficiently store or release oxygen, thus favouring a high catalytic activity and inducing a set of chemical reactions which would otherwise require higher pressures and temperatures,' says Friedrich Esch from the TASC INFM-CNR laboratory. The findings could therefore make an important contribution towards energy conservation, increasing the safety of industrial processes, and reducing environmental impact

Nanotech Buyers and Sellers Stuck in a Pricing Stalemate

 

NEW YORK, /PRNewswire/ -- Are high prices a barrier to nanotechnology commercialization? The answer is yes, according to a new report from Lux Research entitled "Nanotech's Pricing Stalemate Ends." In a remarkable disconnect, 75% of large corporations that buy components based on nanotechnology believe that they hold the pricing power in deals, while 70% of sellers think that in fact they have the upper hand. The result: Deals languish while corporate buyers use delay tactics on overeager sellers.

"Pricing is cited by 45% of corporate buyers as a major challenge that often impedes nanotech deals. Buyers lament that sellers frequently pay attention only to the cost of their own components, missing the big-picture view," said Lux Research Senior Analyst David Lackner. "Only 15% of sellers, however, see pricing as a major problem. They have such faith in their products' performance gains that they view pricing as a minor issue that will work itself out." ...read the wave

Build Big by Thinking Small

 

When it comes to taking the next "giant leap" in space exploration, NASA is thinking small -- really small.

In laboratories around the country, NASA is supporting the burgeoning science of nanotechnology. The basic idea is to learn to deal with matter at the atomic scale -- to be able to control individual atoms and molecules well enough to design molecule-size machines, advanced electronics and "smart" materials.

If visionaries are right, nanotechnology could lead to robots you can hold on your fingertip, self-healing spacesuits, space elevators and other fantastic devices. Some of these things may take 20+ years to fully develop; others are taking shape in the laboratory today...read the wave
