Charging ahead: University of Houston team revealing secrets of electricity-producing materials
Much like humans, materials are capable of some pretty remarkable things when they're placed under pressure. In fact, under the right conditions, materials can even produce electricity. view more (2009-07-28)
Canadian research team reports major breakthrough in lithium battery technology
An NSERC-funded lab at the University Of Waterloo has laid the groundwork for a lithium battery that can store and deliver more than three times the power of conventional lithium ion batteries. view more (2009-05-19)
Advance by chemists may lead to better displays on laptop computers, cell phones
UCLA chemists working at the nanoscale have developed a new, inexpensive means of forcing luminescent polymers to give off polarized light and of confining that light to produce polymer-based lasers. view more (2007-09-18)
Why Nanolayers Buckle when Microbeams Bend
High-strength, ultra-light and elastic carbon materials are commonly used in high-performance sports goods and modern aerospace technology-for example in tennis rackets, racing tyres, heat shields and even guitars. view more (2005-12-16)
Nanocrystals Reveal Activity Within Cells
Researchers at the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory have created bright, stable and bio-friendly nanocrystals that act as individual investigators of activity within a cell. view more (2009-06-17)
Penn Engineers Create Carbon Nanopipettes That Are Smaller Than Cells and Measure Electric Current
University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. view more (2008-01-16)
Strengthening Fluids With Nanoparticles
Researchers at Rensselaer Polytechnic Institute have demonstrated that liquids embedded with nanoparticles show enhanced performance and stability when exposed to electric fields. The finding could lead to new types of miniature camera lenses, cell phone displays, and other microscale fluidic devices. view more (2008-02-20)
A giant step toward tiny functional nanowires
Carving a telephone pole is easy if you have the right tools, say a power saw and some large chisels. And with some much tinier tools you could even carve a design into a paper clip if you wanted to. But shrink your sights down to the nanoscale, to a nanowire that is 1,000 times smaller than the diameter of a paper clip, and you find there are no... view more... (2005-07-01)

Carbon nanotubes have been employed for a variety of uses including composite materials, biosensors, nano-electronic circuits and membranes. view more (2007-10-17)
Magnetic 'handedness' could lead to better magnetic storage devices
Better magnetic storage devices for computers and other electronics could result from new work by researchers in the United States and Germany. view more (2007-05-30)
Go Speed Racer! Revving up the world's fastest nanomotors
In a "major step" toward a practical energy source for powering tomorrow's nanomachines, researchers in Arizona report development of a new generation of sub-microscopic nanomotors that are up to 10 times more powerful than existing motors. Their study is scheduled for the May 27 issue of ACS Nano, a monthly journal. view more (2008-05-01)
Tethered Molecules Act as Light-Driven Reversible Nanoswitches
The ability to see is based on molecules in the eye that flip from one conformation to another when exposed to visible light. view more (2008-06-24)
'Sticky nanotubes' hold key to future technologies
Researchers at Purdue University are the first to precisely measure the forces required to peel tiny nanotubes off of other materials, opening up the possibility of creating standards for nano-manufacturing and harnessing a gecko's ability to walk up walls. view more (2008-04-29)
Engineers build DNA 'nanotowers' with enzyme tools
Duke engineers have added a new construction tool to their bio-nanofabrication toolbox. Using an enzyme called TdTase, engineers can vertically extend short DNA chains attached to nanometer-sized gold plates. This advance adds new capability to the field of bio-nanomanufacturing. view more (2005-10-13)
Simplicity is crucial to design optimization at nanoscale
MIT researchers who study the structure of protein-based materials with the aim of learning the key to their lightweight and robust strength have discovered that the particular arrangement of proteins that produces the sturdiest product is not the arrangement with the most built-in redundancy or the most complicated pattern. view more (2009-02-05)
New theory explains electronic and thermal behavior of nanotubes
Researchers at the University of Illinois at Urbana-Champaign have made an important theoretical breakthrough in the understanding of energy dissipation and thermal breakdown in metallic carbon nanotubes. view more (2006-01-20)
New report explores nanotechnology's future
Controlling the properties and behavior of matter at the smallest scale—in effect, "domesticating atoms"—can help to overcome some of the world's biggest challenges, concludes a new report on how diverse experts view the future of nanotechnology. view more (2007-04-23)
Nanostructures can pose big measurement problems
Materials scientists will tell you that to best understand, characterize and eventually utilize the properties of a specific material, you have to be able to define how the atoms within it are arranged. view more (2007-04-30)
