KAUST team alters atomic composition of MoS2 to boost performance as water-splitting catalyst for H2 production

Green Car Congress

Researchers at KAUST have developed and used a novel way of increasing the chemical reactivity of a two-dimensional molybdenum disulfide material to produce a cheap and effective catalyst for water splitting to produce hydrogen. This technique may also have potential benefits for other manufacturing industries. —Lain-Jong Li.

Iowa State team develops hybrid technology to create biorenewable nylon

Green Car Congress

Engineers at Iowa State University have developed a hybrid process that combines bio- and electrocatalysis to convert glucose into bio-based unsaturated nylon-6,6—which has the advantage of an extra double bond in its backbone that can be used to tailor the polymer’s properties. Their study is published in the 12 Feb. Resources. Carraher, N.

Forecast: Algae-Based Biofuels Production to Reach 61M Gallons per Year by 2020

Green Car Congress

The European Union (EU) market, which is home to about 30% of algae activity, will be limited initially by the industry’s focus on university research, and later by insufficient access to water, land, and nutrient sources. Pilot- and demonstration-scale facilities are beginning to break ground across the country.
