Engineers discover nanoscale balancing act that mirrors forces at work in living systems

Posted: 23 Aug 2011 03:05 PM PDT

A delicate balance of atomic forces can be exploited to make nanoparticle superclusters that are uniform in size -- an attribute that's important for many nanotech applications but hard to accomplish, researchers say. The same type of forces are at work bringing the building blocks of viruses together, and the inorganic supercluster structures in this research are in many ways similar to viruses.

Unexpected adhesion properties of graphene may lead to new nanotechnology devices

Graphene, considered the most exciting new material under study in the world of nanotechnology, just got even more interesting, according to a new study.

World-record pulsed magnetic field achieved; Lab moves closer to 100-tesla mark

Researchers have set a new world record for the strongest magnetic field produced by a nondestructive magnet. The scientists achieved a field of 92.5 tesla on Thursday, Aug. 18, taking back a record that had been held by a team of German scientists and then, the following day, surpassed their achievement with a whopping 97.4-tesla field. Such a powerful nondestructive magnet could have a profound impact on a wide range of scientific investigations, from how to design and control material functionality to research into the microscopic behavior of phase transitions.

Human gait could soon power portable electronics
