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)
World-leading microscope shows more detail than ever
A unique 3-dimensional microscope that works in a new way is giving unprecedented insight into microscopic internal structure and chemical composition. It is revealing how materials are affected, over time, by changes in temperature, humidity, weight load and other conditions. view more (2006-05-03)
Shrinking magnetic storage media down to the nanoscale
In the world of electronic and magnetic devices, the goal is to get smaller. view more (2006-03-14)
Scientists discover pentagonal ice
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)
Scientists determine strength of 'liquid smoke'
Researchers have created a 3D image of a material referred to as "liquid smoke." Aerogel, also known as liquid smoke or "San Francisco fog," is an open-cell polymer with pores smaller than 50 nanometers in diameter. view more (2008-07-30)
Rapid movements of living biomolecules visualised
Dutch researcher Chris Molenaar has made the rapid movements of proteins, DNA and RNA molecules visible in living cells. With this technique researchers can study the dynamics of biomolecules in their natural environment. Molenaar developed a method which makes it possible to follow the movements of RNA molecules in living cells. The researcher... view more... (2003-06-24)
Where Broken DNA is Repaired
Ionizing radiation, toxic chemicals, and other agents continually damage the body's DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer. view more (2007-08-03)
Video shows buckyballs form by 'shrink wrapping'
The birth secret of buckyballs -- hollow spheres of carbon no wider than a strand of DNA -- has been caught on tape by researchers at Sandia National Laboratory and Rice University. An electron microscope video and computer simulations show that "shrink-wrapping" is the key; buckyballs start life as distorted, unstable sheets of... view more... (2007-10-29)
'High Q' NIST nanowires may be practical oscillators
Nanowires grown at the National Institute of Standards and Technology (NIST) have a mechanical "quality factor" at least 10 times higher than reported values for other nanoscale devices such as carbon nanotubes, and comparable to that of commercial quartz crystals. view more (2007-11-28)
Materials Today, May 2003
-------------------------- This month's features -------------------------- The fabrication of materials and devices on the nanoscale may require a new approach"¦ * Shuguang Zhang of MIT is following nature's example and building materials from the bottom up. * Materials Today investigates the latest developments in extreme UV lithography and... view more...

Signaling proteins may represent biomarkers for melanoma
For the first time, researchers studying patients with abnormal moles have identified proteins that could help predict whether such moles will progress into melanoma, the deadliest form of skin cancer. view more (2006-04-06)
Magnet Lab researchers make observing cell functions easier
Now that the genome (DNA) of humans and many other organisms have been sequenced, biologists are turning their attention to discovering how the many thousands of structural and control genes -- the "worker bees" of living cells that can turn genes on and off -- function. view more (2008-05-09)
Precision bonding makes tiny high performance actuators possible
Using a new precision bonding process they developed, Penn State researchers have designed and fabricated tiny new piezoelectric microactuators - the largest only a hair's breadth wide - based on coupling commercially available materials with existing micromachining technology. view more (2005-10-04)

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)
University of Saskatchewan and Canadian Synchrotron researchers shed light on esophageal disease
Canadian Light Source (CLS) staff scientist Luca Quaroni and Dr. Alan Casson, Head of the Department of Surgery at the University of Saskatchewan (U of S) used the synchrotron's infrared microscope to identify tissue afflicted with a condition known as Barrett's Esophagus from chemical fingerprints associated with the disease, which can lead to... 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)
Guarding giants with tiny protectors
How do you build an infrared (IR) camera that is small enough to fit on a mini-unmanned aerial vehicle (UAV) without cryogenic cooling? Call in the nanobots. view more (2005-10-24)
