Building blocks of the future
Structure and properties of carbon nanostructures The discovery in 1985 of fullerenes, tiny carbon balls of nanometer dimensions, ushered in a new era in international science. Only a few years later (1991) scientific interest also started to focus on so-called carbon nanotubes. The discovery of improved production methods (1996) has meanwhile... view more... (2002-12-05)
Harvard scientists bend nanowires into 2-D and 3-D structures
Taking nanomaterials to a new level of structural complexity, scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional structures with correspondingly advanced functions. view more (2009-10-22)
Penn materials scientist finds plumber's wonderland on graphene
Engineers from the University of Pennsylvania, Sandia National Laboratories and Rice University have demonstrated the formation of interconnected carbon nanostructures on graphene substrate in a simple assembly process that involves heating few-layer graphene sheets to sublimation using electric current that may eventually lead to a new paradigm... view more...

Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights. view more (2008-07-07)
Scientists create metal that pumps liquid uphill
In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a simple slab of metal that lifts liquid using the same principle-but does so at a speed that would make nature envious. view more (2009-06-03)
'Smart' nanoprobes light up disease
Researchers from Rice University's Center for Biological and Environmental Nanotechnology (CBEN) have developed a "smart" beacon hundreds of times smaller than a human cell that is programmed to light up only when activated by specific proteases. view more (2005-08-02)
