Process Cleans Wastewater, Generates Electricity, Desalinates Seawater

A team of researchers from the U.S. and China modified a microbial fuel cell - a device that uses naturally occurring bacteria to convert wastewater into clean water producing electricity - so it could desalinate salty water. The new process cleans wastewater, generates electricity, and removes 90 percent of salt from brackish water or seawater.

Nanocrystals Could Aid in Solid-State Lighting and CO2 Storage

Scientists at Berkeley Lab have created non-toxic magnesium oxide nanocrystals whose size can be adjusted within just a few nanometers. The nanocrystals glow blue when exposed to ultraviolet light, and could be a bright candidate for lighting that consumes less energy and has a longer lifespan. The nanocrystals could also allow researchers to probe a key pathway in carbon dioxide sequestration.

Reinventing the Tuktuk

In large cities across Asia, auto rickshaws (tuktuks) are one of the most important means of transportation. These tuktuks produce considerable CO2 emissions and air pollution, and their drivers are underpaid. Students participating in the Hybrid Auto Rickshaw project sought to cut CO2 emissions by 40%, while improving the economic positions of drivers.
