'World's smallest controlled heat source' studies explosives at the nanoscale
Using nanometer scale analysis techniques and quantities too small to explode, researchers have mapped the temperature and length-sale factors that make energetic materials - otherwise known as explosives - behave the way they do.   view more (2006-09-11)

3.2 Billion-Year-Old Surprise: Earth Had Strong Magnetic Field
Geophysicists at the University of Rochester announce in today's issue of Nature that the Earth's magnetic field was nearly as strong 3.2 billion years ago as it is today.   view more (2007-04-05)

Sandia researchers construct carbon nanotube device that can detect colors of the rainbow
Researchers at Sandia National Laboratories have created the first carbon nanotube device that can detect the entire visible spectrum of light, a feat that could soon allow scientists to probe single molecule transformations, study how those molecules respond to light, observe how the molecules change shapes, and understand other fundamental... view more...

Rice University researchers create 'nanorice'
Who better to invent "nanorice" than researchers at Rice University? But marketing and whimsy weren't what motivated the team of engineers, physicists and chemists from Rice's Laboratory for Nanophotonics (LANP) to make rice-shaped particles of gold and iron oxide.   view more (2006-03-15)

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 from fewer wafers.   view more (2005-07-15)

JHU chemists devise self-assembling 'organic wires'
From pacemakers constructed of materials that so closely mimic human tissues that a patient's body can't discern the difference to devices that bypass injured spinal cords to restore movement to paralyzed limbs, the possibilities presented by organic electronics read like something from a science fiction novel.   view more (2008-10-24)

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 commercialization.   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 effective risk research strategy.   view more (2007-09-14)

Scientists at the University of Liverpool have discovered a five-sided ice chain structure that could be used to modify future weather patterns.   view more (2009-04-07)

Giant magnetocaloric materials could have large impact on the environment
Materials that change temperature in magnetic fields could lead to new refrigeration technologies that reduce the use of greenhouse gases, thanks to new research at the U.S. Department of Energy's Argonne National Laboratory and Ames National Laboratory.   view more (2007-06-20)

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)

New statistical technique improves precision of nanotechnology data
A new statistical analysis technique that identifies and removes systematic bias, noise and equipment-based artifacts from experimental data could lead to more precise and reliable measurement of nanomaterials and nanostructures likely to have future industrial applications.   view more (2009-07-01)

New metamaterials that bend light backwards bring invisibility cloaks 1 step closer
Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and, to the delight of science-fiction and... view more...

'Instant on' computing
The ferroelectric materials found in today's "smart cards" used in subway, ATM and fuel cards soon may eliminate the time-consuming booting and rebooting of computer operating systems by providing an "instant-on" capability as well as preventing losses from power outages.   view more (2009-04-20)

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 Project on Emerging Nanotechnologies.   view more (2007-04-26)

Hidden order found in a quantum spin liquid
An international team, including scientists from the London Center for Nanotechnology, has detected a hidden magnetic "quantum order" that extends over chains of 100 atoms in a ceramic without classical magnetism. The findings, which are published today, July 26, by Science, have implications for the design of devices and materials for... view more... (2007-07-27)

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)
