MOF-coated mesh membranes separate oil from water

Current oil-water separation technologies, such as centrifugation, filtration, dissolved air flotation, distillation, oil skinners, adsorption and electrochemical methods, are of low efficiency and consume a lot of energy during complex separation processes. Mesh membranes have attracted much interest lately, and…

Progress toward using ammonia as a hydrogen carrier for fuel cells

In order for ammonia to serve as a hydrogen carrier, it is necessary to develop separation techniques that can reliably recover H2 from the decomposition of NH3 with sufficient purity for operating proton-exchange membrane (PEM) fuel cells. A step in…

Mechanically strong aerogels get closer to commercialization

Aerogels — ultralight, insulating and heat-resistant nanoporous solids — offer benefits in many applications, but commercially available aerogels are typically limited to just two formats: particles and blankets. Aerogel Technologies, LLC (Boston, Mass.; www.aerogeltechnologies.com) is currently constructing a pilot plant…
