Rice U. discovery may boost memory technology

Rice University scientists make tantalum oxide practical for high-density devices

12-Aug-2015

Scientists at Rice University have created a solid-state memory technology that allows for high-density storage with a minimum incidence of computer errors. The memories are based on tantalum oxide, a common insulator in electronics. Applying voltage to a 250-nanometer-thick sandwich of graphene, ...

Buckyballs offer environmental benefits

In Rice University study, treated carbon-60 molecules remove metals from liquids

12-Feb-2015

Treated buckyballs not only remove valuable but potentially toxic metal particles from water and other liquids, but also reserve them for future use, according to scientists at Rice University.The Rice lab of chemist Andrew Barron has discovered that carbon-60 fullerenes (aka buckyballs) that ...
