Polymer-based membranes offer alternative to thermal processes for separating hydrocarbon and crude oil mixtures

Green Car Congress

Polymer-based membranes developed at KAUST could enable greener and cheaper industrial separation approaches. Their stability and selectivity can be tuned by thermal crosslinking to separate simple hydrocarbon mixtures and complex crude oil fractions. A paper on the work is published in Science. —Chisca et al. Vasylevskyi, S.,

Motherson Group collaborating with UBQ to bring carbon-negative thermoplastics into auto parts

Green Car Congress

Targeting the plastic industry first, and leveraging the material’s thermoplastic affinity to polymers, they company developed several commercial grades of UBQ material. UBQ GHG Neutralizer additives enable processors to directly compensate cO 2 -equivalent emissions (GHG) generated by plastic polymers. Polymers typically emit 1.9

Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. 60% rubber polymers; 20?35% when complex.

New LLNL membrane bridges operational gap between low- and high-temperature PEM fuel cells; potential for lower cost systems

Green Car Congress

Currently, two main classes of polymer-based fuel cells exist. The Los Alamos team collaborated with Fujimoto at Sandia to prepare quaternary ammonium functionalized polymers. These PEMs can conduct protons through stable ionic pair complexes and enable fuel cell operation at temperatures from 80 to 180 ËšC. —Lee et al.
