From the structure of DNA to nautical rope to distant spiral galaxies, helical
forms are as abundant as they are useful in nature and manufacturing alike.
Researchers at the Harvard
School of Engineering and Applied Sciences (SEAS) have discovered a way
to synthesize and control the formation of nanobristles, akin to tiny hairs,
into helical clusters and have further demonstrated the fabrication of such
highly ordered clusters, built from similar coiled building blocks, over multiple
scales and areas.
Using a simple chemical process, scientists at Cornell
and DuPont have invented a method of preparing carbon nanotubes for suspension
in a semiconducting "ink," which can then be printed into such thin,
flexible electronics as transistors and photovoltaic materials.
Scientists at DuPont
and Cornell University in Ithaca, N.Y., have used a simple chemical process
to convert mixtures of metallic and semiconducting carbon nanotubes into solely
semiconducting carbon nanotubes with electrical characteristics well-suited
for plastic electronics.
Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offe...
Dwellings in colonies on the moon one day may be built with new, highly durable bricks developed by students from the College of Engineering at Virginia Tech.
Cookson Group plc ("Cookson"), a leading materials science company, announces that on 23 December 2008 it completed the disposal of its Hi-Tech Ceramic filters business ("Hi-Tech") to companies owned ...
For those who love “green” compact fluorescent bulbs but hate their cold light, here’s some good news: Researchers are closer to flipping the switch on cheaper, richer LED-type room lighting.

new Magellan™ extreme high-resolution scanning electron microscope (XHR
SEM) allows scientists and engineers to quickly see 3D surface images at many
different angles and at resolutions below one nanometer.
Two new high-resolution transmission electron microscopes, co-financed by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), are set to open up new opportunities for research in physics and materials ...
Researchers at MIT have made significant progress in understanding a class of materials that has resisted analysis for decades. Their findings could lead to the rapid discovery of a variety of useful new kinds of glass m...
