Shape Matters in the Case of Cobalt Nanoparticles

Shape is turning out to be a particularly important feature of some commercially important nanoparticles-but in subtle ways. New studies* by scientists at the National Institute for Standards and Technology (NIST) show that changing the shape of cobalt nanoparticles from spherical to cubic can fundamentally change their behavior.

Scientists Discover 'Magnetic Superatom'

A team of Virginia Commonwealth University scientists has discovered a 'magnetic superatom' - a stable cluster of atoms that can mimic different elements of the periodic table – that one day may be used to create molecular electronic devices for the next generation of faster computers with larger memory storage.

Chemical-Induced Switching of Polymer Magnetism Achieved at Room Temperature

When we smell an aroma or taste a flavor, we convert a chemical stimulus - adsorption of a particular molecule - into an information signal. Researchers are seeking to reproduce such interactions, in a simplified form, to develop new types of chemical sensors for practical and safety applications.

Scientists on the Trail of "Colossal Magnetoresistance Effect"

Millions of people today carry around pocket-sized music players capable of holding thousands of songs, thanks to the discovery 20 years ago of a phenomenon known as the "giant magnetoresistance effect," which made it possible to pack more data onto smaller and smaller hard drives.

Scientist Discover New Superconductor Element

James S. Schilling, Ph.D., professor of physics in Arts + Sciences at Washington University in St. Louis, and Mathew Debessai, Ph.D., - his doctoral student at the time - discovered that europium becomes superconducting at 1.8 K and 80 GPa of pressure, making it the 53rd known elemental superconductor and the 23rd at high pressure.
