 | Two of the Florida State University's most accomplished scientists recently joined forces on a collaborative research project that has yielded groundbreaking results involving an unusual family of crystalline minerals. Their findings could lay the groundwork for future researchers seeking to develop a new generation of computer chips and other information-storage devices that can hold vast amounts of data and be strongly encrypted for security purposes. ...> Full Article |
 | UCLA chemists report creating a synthetic "gene," which could capture heat-trapping carbon dioxide emissions. The research is published in the Feb. 12, 2010, issue of the journal Science. Carbon dioxide contributes to global warming, rising sea levels and increased acidity of oceans. ...> Full Article |
 | In the January 29 issue of Science, a team from Harvard led by Vinothan Manoharan and Michael Brenner, presents additional clues to how and why groups of atoms and molecules may favor less symmetrical and more complex, flexible geometric patterns.
The answer relates to a familiar concept in physics -- entropy. The researchers literally first caught sight of the link by using magnetic "stick and ball" construction toys. ...> Full Article |
X-rays can do a lot of useful things but who knew they could cause crystals to form? Northwestern University researchers have discovered that X-rays can trigger the formation of a new type of crystal: charged cylindrical filaments ordered like a bundle of pencils experiencing repulsive forces, which is unknown in crystals. The results open the door to using X-rays to control the structure of materials or to develop novel biomedical therapies.

To make thin films for semiconductors in electronic devices, layers of atoms must be grown in neat, crystalline sheets. But while some materials grow smooth crystals, others tend to develop bumps and defects -- a serious problem for thin-film manufacturing. Cornell physicists shed new light on how atoms arrange themselves into thin films.
