Bridging the Gap between Climate and Weather

reanalysis of historic storm

The distinction between climate and weather was expressed most succinctly by science fiction writer Robert A. Heinlein: “Climate is what you expect; weather is what you get.” But as global warming produces more noticeable changes on a planetary scale, how do we even know what to expect in a particular region?  [MORE]

Overcoming Nanocrystals’ Resistance to Doping

Doping pure silicon with small quantities of impurities enables engineers to tailor the material's properties

A small amount of dopant can make a big difference: one atom of dopant per 10,000 silicon atoms is considered heavy doping in today’s semiconductor manufacturing; light doping could mean a ratio of 1:100,000,000. But materials scientists would like to dope semiconductor nanocrystals that may have fewer than 10,000 atoms to begin with, because nanoelectronics holds the promise of more efficient solar cells, electroluminescent devices, computers, and much more.
