Experiments Show Absence of Thermoelectric Effect in Metallic Carbon Nanotubes

Metallic carbon nanotubes have been proposed as interconnects in future electronic devices packed with high-density nanoscale circuits. Recent experiments have shown the absence of the thermoelectric effect in metallic carbon nanotubes. Building upon earlier theoretical work, researchers at the University of Illinois say they can explain this peculiar behavior, and put it to good use.

Report Highlights FDA’s Regulatory Challenges Posed by Nanomaterials

The ability of the Food and Drug Administration (FDA) to regulate the safety of dietary supplements using nanomaterials is severely limited by lack of information, lack of resources and the agency's lack of statutory authority in certain critical areas, according to a new expert report released by the Project on Emerging Nanotechnologies (PEN).

NIST Researchers Develop New Technique to Form Nanotubes for Gas Sensing Applications

In a recent paper,* researchers at the National Institute of Standards and Technology (NIST) described a new method for creating gas detectors so sensitive that some day they may be able to register these tiny emissions from a single cell, providing a new way to determine if drugs or nanoparticles harm cells or to study how cells communicate with one another.

Inexpensive Process that Gets Nanotubes to Obediently Line Themselves Up

A new study* from the National Institute of Standards and Technology (NIST) and Rice University, however, offers an inexpensive process that gets nanotubes to obediently line themselves up-that is, self-assemble-in neat rows, more like ducks.
