Physicists at the University of Pennsylvania have characterized an aspect of graphene film behavior by measuring the way it conducts electricity on a substrate. This milestone advances the potential application of graphene, the ultra-thin, single-atom thick carbon sheets that conduct electricity faster and more efficiently than silicon, the current material of choice for transistor fabrication.

Read moreA paper in this week's nature Nanotechnology outlines a roadmap for harnessing nanomotors for a broad range of applications, ranging from nanoscale sensing, and transport to assembly. It focuses on two broad classes of nanomotors that burn chemical energy to move along linear tracks: assembly nanomotors and transport nanomotors.

Aerogel, also known as liquid smoke or 'San Francisco fog', is an open-cell polymer with pores smaller than 50 nanometers in diameter. For the first time, Lawrence Livermore and Lawrence Berkeley scientists have peered into this material and created three-dimensional images to determine its strength and potential new applications.
