When Charles Sykes, Tufts University assistant chemistry professor, says he loves playing with blocks, he's not referring to the typical kids' toys. Instead, he's talking about his fascination with seeing atoms and molecules move on a computer screen in front of him and using technology to move the molecules himself to see how they react to various surfaces.
A well-established physical law describes the transfer of heat between two objects, but some physicists have long predicted that the law should break down when the objects are very close together. Scientists had never been able to confirm, or measure, this breakdown in practice.
A revision to an important ASTM nanotechnology standard incorporates a large-scale interlaboratory study that took place in 2008. The revised standard, ASTM E2490, Guide for Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS), is under the jurisdiction of Subcommittee E56.02 on Characterization: Physical, Chemical and Toxicological Properties, part of ASTM International Committee E56 on Nanotechnology.
Recent research into the properties of graphene nanoribbons provides two new reasons for using the material as interconnects in future computer chips. In widths as narrow as 16 nanometers, graphene has a current carrying capacity approximately a thousand times greater than copper-while providing improved thermal conductivity.
With products that range from carpets to kites, you'd think Rice University chemist Bob Hauge was running a department store. What he's really running is a revolution in the world of carbon nanotechnology.
Powerful new radio technologies that promise blisteringly fast WiFi have been given a boost by a team of European researchers' cutting-edge work on miniscule microchips.
The work, led by Belgian-based nanotechnology...
Maternal exposure to nanoparticles of titanium dioxide (TiO2) affects the expression of genes related to the central nervous system in developing mice. Researchers writing in BioMed Central's open access journal Part...
