New infrared tool measures silicon wafer thickness
In the last few years, semiconductor circuit features have shrunk to sub-100 nanometer (nm) dimensions, while the size of the thin silicon wafers that these circuits are constructed on has grown from 200 millimeters (mm) to 300 mm (about 12 inches). The payoff is a higher yield of finished devices... view more (2005-07-15)

New nanoscale engineering breakthrough points to hydrogen-powered vehicles
Researchers at the U.S. Department of Energy's Argonne National Laboratory have developed an advanced concept in nanoscale catalyst engineering - a combination of experiments and simulations that will bring polymer electrolyte membrane fuel cells for hydrogen-powered vehicles closer to massive... view more (2007-03-06)

Federal research plan to determine nanotech risks fails to deliver
Almost a year in the making, a federal plan to prioritize research on the potential environmental, health, and safety (EHS) impacts of nanoscale materials has so many failings that its begs the question as to whether the government's 13-agency nanotechnology research effort is able to deliver an... view more (2007-09-14)

Ultraviolet Light Reveals Secrets of Nanoscale Electronic Materials
An international team of scientists has used a novel technique to measure, for the first time, the precise conditions at which certain ultrathin materials spontaneously become electrically polarized.   view more (2006-10-25)

Quantum coherence possible in incommensurate electronic systems
Researchers at the University of Illinois at Urbana-Champaign have demonstrated that quantum coherence is possible in electronic systems that are incommensurate, thereby removing one obstacle in the development of quantum devices.   view more (2006-11-03)

Nanotechnology provides 'green' path to environmentally sustainable economy
As products made with nanometer-scale materials and devices spread to more industries and markets, there is a growing opportunity and responsibility to leverage nanotechnology to reduce pollution, conserve resources and, ultimately, build a "clean" economy, advises a new report from the... view more (2007-04-26)

Tiny crystals promise big benefits for solar technologies
Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials that previously thought.   view more (2006-01-05)

MIT researcher sees big impact of little cracks
An MIT researcher's atom-by-atom simulation of cracks forming and spreading may help explain how materials fail in nanoscale devices, airplanes and even in the Earth itself during a quake.   view more (2006-01-19)

New nanocomposites may mean more durable tooth fillings
The mouth is a tough environment-which is why dentists do not give lifetime guarantees. Despite their best efforts, a filling may eventually crack under the stress of biting, chewing and teeth grinding, or secondary decay may develop where the filling binds to the tooth.   view more (2007-04-30)

New JILA apparatus measures fast nanoscale motions
A new nanoscale apparatus developed at JILA—a tiny gold beam whose 40 million vibrations per second are measured by hopping electrons—offers the potential for a 500-fold increase in the speed of scanning tunneling microscopes (STM), perhaps paving the way for scientists to watch atoms... view more (2007-03-19)

Speed bumps less important than potholes for graphene
For electrical charges racing through an atom-thick sheet of graphene, occasional hills and valleys are no big deal, but the potholes-single-atom defects in the crystal-they're killers.   view more (2007-07-13)

Sharply-tuned nanostrings work at room temperature
Using a fast, low-cost fabrication technique that allows inexpensive testing of a wide variety of materials, Cornell researchers have come up with nanoscale resonators - tiny vibrating strings - with the highest quality factor so far obtainable at room temperature for devices so small.   view more (2006-07-17)

Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures.   view more (2007-03-12)

Molecular spintronic action confirmed in nanostructure
Researchers at the National Institute of Standards and Technology (NIST) have made the first confirmed "spintronic" device incorporating organic molecules, a potentially superior approach for innovative electronics that rely on the spin, and associated magnetic orientation, of electrons.   view more (2006-10-13)

All done with mirrors: NIST microscope tracks nanoparticles in 3-D
A clever new microscope design allows nanotechnology researchers at the National Institute of Standards and Technology (NIST) to track the motions of nanoparticles in solution as they dart around in three dimensions.   view more (2008-03-11)

Bacteria and nanofilters - the future of clean water technology
Bacteria often get bad press, with those found in water often linked to illness and disease. But researchers at The University of Nottingham are using these tiny organisms alongside the very latest membrane filtration techniques to improve and refine water cleaning technology.   view more (2008-02-25)

University of Pennsylvania engineers discover natural 'workbench' for nanoscale construction
Engineers at the University of Pennsylvania have taken a step toward simplifying the creation of nanostructures by identifying the first inorganic material to phase separate with near-perfect order at the nanometer scale.   view more (2007-07-18)

Cheaper LEDs from breakthrough in zinc oxide (ZnO) nanowire research, Nano Letters study says
Engineers at UC San Diego have synthesized a long-sought semiconducting material that may pave the way for an inexpensive new kind of light emitting diode (LED) that could compete with today's widely used gallium nitride LEDs, according to a new paper in the journal Nano Letters.   view more (2007-01-04)

A new window into the deformation of nanoscale materials
Materials on the nanoscale don't always have the same properties they would in bulk; for one thing, nanomaterials are often a lot harder. Unlike most bulk materials, a crystal that is small enough can be perfect, free of defects, capable of achieving strength near its ideal theoretical limit.   view more (2006-08-14)

U-M research: New plastic is strong as steel, transparent
