Study explains unexpected conductivity of nanoscale silicon
When graduate student Pengpeng Zhang successfully imaged a piece of silicon just 10 nanometers-or a millionth of a centimeter-in thickness, she and her University of Wisconsin-Madison co-researchers were puzzled.   view more (2006-02-09)

Turning Waste Material into Ethanol
Say the word "biofuels" and most people think of grain ethanol and biodiesel. But there's another, older technology called gasification that's getting a new look from researchers at the U.S. Department of Energy's Ames Laboratory and Iowa State University. By combining gasification with... view more (2008-08-14)

World's smallest radio uses single nanotube to pick up good vibrations
Physicists at the University of California, Berkeley, have built the smallest radio yet - a single carbon nanotube one ten-thousandth the diameter of a human hair that requires only a battery and earphones to tune in to your favorite station.   view more (2007-11-01)

Alternative steel loses its Achilles heel
Improved domestic and industrial cutting tools, stronger hip joints and better medical instruments should result from latest research looking at ceramic alternatives to steel. The key to these advances lies in zirconia, a ceramic with steel-like strength and hardness and high resistance to wear... view more (2003-01-31)

NIST imaging system maps nanomechanical properties
The National Institute of Standards and Technology (NIST) has developed an imaging system that quickly maps the mechanical properties of materials-how stiff or stretchy they are, for example-at scales on the order of billionths of a meter.   view more (2007-12-13)

New reference materials support industrial zeolites
The National Institute of Standards and Technology (NIST) has issued three new reference materials to support researchers studying the properties of commercially important zeolites.   view more (2006-09-18)

New coating is virtual black hole for reflections
Researchers have created an anti-reflective coating that allows light to travel through it, but lets almost none bounce off its surface. At least 10 times more effective than the coating on sunglasses or computer monitors, the material, which is made of silica nanorods, may be used to channel light... view more (2007-03-05)

NYU chemists create 'nanorobotic' arm to operate within DNA sequence
New York University chemistry professor Nadrian C. Seeman and his graduate student Baoquan Ding have developed a DNA cassette through which a nanomechanical device can be inserted and function within a DNA array, allowing for the motion of a nanorobotic arm.   view more (2006-12-08)

MIT researchers probe bones' tiny building blocks
In work that could lead to more effective diagnoses and treatments of bone diseases using only a pinhead-sized sample of a patient's bone, MIT researchers report a first-of-its-kind analysis of bone's mechanical properties.   view more (2007-05-25)

Scientists use nanomaterials to localize and control drug delivery
Using nanotechnology, scientists from UCLA and Northwestern University have developed a localized and controlled drug delivery method that is invisible to the immune system, a discovery that could provide newer and more effective treatments for cancer and other diseases.   view more (2008-01-23)

Smart thin film membranes adopt properties of guest molecules
Virginia Tech researchers announced last year that they had created a nanostructured membrane that incorporates DNA base pairs in order to impart molecular recognition and binding ability to the synthetic material.   view more (2007-03-29)

Early detection of Alzheimer's disease a possibility
Research investigating concentrations of magnetite, a magnetic form of iron, in Alzheimer's disease tissue has produced preliminary results that suggest the possibility of developing a technique to detect Alzheimer's disease before clinical symptoms appear. The research*, published in Biology... view more (2003-04-07)

Nanoparticle exposures happen, says expert
Some nanotechnology fanciers suggest that, like proverbial birds of a feather, engineered nanoscale materials will flock - or clump - together. This tendency, they maintain, should reduce or eliminate risks as nanotechnology manufacturing increases and the number of nanotechnology-enabled products... view more (2007-10-12)

Gold Nanoparticles Emit Intense Heat, Study Finds
Nanoparticles of gold can act as tiny, precise and powerful heaters, which potentially could be used in biomedical applications, according to a new study.   view more (2006-03-31)

Molecular trains scheduled at new biotechnology institute
As governments worldwide pour billions into programmes to exploit the potential of nanotechnology, Leeds aims to make its mark with its newly-established Interdisciplinary Institute in Bionanosciences. Molecular-scale trains and submarines that will carry loads such tiny doses of drugs and virtual... view more (2004-02-23)

A Colorful Approach to Solar Energy
Revisiting a once-abandoned technique, engineers at the Massachusetts Institute of Technology (MIT) have successfully created a sophisticated, yet affordable, method to turn ordinary glass into a high-tech solar concentrator.   view more (2008-07-11)
