There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Facundo FernándezIf you’ve ever rubbed a balloon against your head to make your hair stand on end, you’ve experienced triboelectricity. Researchers at Georgia Tech are now putting such electricity—which is really just an electric charge generated by friction—to good use: They’re using triboelectricity to drive the ionization of molecules in a mass spectrometer.
Materials scientist Zhong Lin Wang, mass spectrometrist Facundo M. Fernández, and coworkers replace the high-voltage power supplies that usually drive ionization with devices called triboelectric nanogenerators, or TENGs. The researchers published their findings in Nature Nanotechnology. Wang and Fernandez are professors in the School of Chemistry and Biochemistry.
