NIST Gets the Dirt on Soil

NIST has issued three new certified reference materials for soil. Intended for use as controls in testing laboratories, the new Standard Reference Materials (SRMs) will aid in determining soil quality, detecting soil contamination, and monitoring cleanup efforts from accidental spills or atmospheric deposition.

Scrubbing Out Sulfur

Pacific Northwest National Laboratory researchers have developed a reusable organic liquid that can pull harmful gases like carbon dioxide or sulfur dioxide out of industrial emissions from power plants. Power plants could capture double the amount of harmful gases in a way that uses no water, less energy, and saves money.

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.

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.
