Breaking Planck's Law at the Nanoscale

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.

Findings Open Door to Improved Microbial Fuel Cell Architecture

In their most recent experiments with Geobacter, the sediment-loving microbe whose hairlike filaments help it to produce electric current from mud and wastewater, Derek Lovley and colleagues at the University of Massachusetts Amherst supervised the evolution of a new strain that dramatically increases power output per cell and overall bulk power.

Revision to an Important ASTM Nanotechnology Standard Incorporates a Large-scale Interlaboratory Study

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.

Research into Graphene Nanoribbons Provides New Reasons for Using it as Interconnects In Future Computer Chips

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.

Rice Scientists Use Nanomaterials To Grow Flying 'Odako' Kites

In a paper published this month in Nano Research, Hauge's Rice University team describes a method for making "odako," bundles of single-walled carbon nanotubes (SWNT) named for the traditional Japanese kites they resemble. It may lead to a way to produce meter-long strands of nanotubes, which by themselves are no wider than a piece of DNA.

Lab on a Chip: Highly Sensitive Detection of Bacteria with Magnetic Nanoparticles and a Miniaturized NMR Method

Researchers working with Ralph Weissleder at Harvard Medical School have now developed a very simple process for the rapid detection of pathogens that requires no further sample preparation. As reported in the journal Angewandte Chemie, this technique is based on magnetic nanoparticles and a nuclear magnetic resonance (NMR) measurement.
