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.

Discovery May Aid Development of Pharmaceuticals

The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically identical. However, there can be significant differences.
