Researchers build a transistor from a molecule and a few atoms

An international team of physicists has used a scanning tunneling microscope to create a minute transistor consisting of a single molecule and a small number of atoms. The observed transistor action is markedly different ...

A database of enzyme diversity

Scientists have a constructed a new database of the diversity in an enzyme that is used by microorganisms to metabolize sulfur.

Manipulating complex molecules by hand

Jülich scientists have developed a new control technique for scanning probe microscopes that enables the user to manipulate large single molecules interactively using their hands. Until now, only simple and inflexibly-programmed ...

Clean smell doesn't always mean clean air

Some of the same chemical reactions that occur in the atmosphere as a result of smog and ozone are actually taking place in your house while you are cleaning. A researcher in Drexel's College of Engineering is taking a closer ...
