Exhaust Plume Analyzer

Exhaust plumes emanating from smoke stacks at power plants or other industrial facilities can have adverse impacts on local aviation during periods of calm winds. Adverse impacts can be exacerbated if the temperature is low or the atmosphere is unstable. While low oxygen concentrations and elevated temperatures inside the...

Cobalt Oxygen-Evolving Catalysts for Clean Solar Fuel

By splitting a water molecule into two atoms of hydrogen and one of oxygen, scientists can use the Sun’s energy to make a clean fuel. Splitting a water molecule requires a metal catalyst to get the reaction started. Recently, much scientific attention has focused on cobalt, a relatively...

Briefs: Electronics & Computers

Batteries and combustion engines each have distinctive benefits and limitations. Batteries have simple construction and operate silently; however, their energy density (i.e., the energy per unit volume) is poor, and...
