EPoSil: electroactive polymers for generating electricity from wave power

Green Car Congress

The EPoSil concept uses dielectric elastomer transducers to generate electrical energy from wave motion. A German consortium involving four companies and and two universities is developing dielectric elastomers (electroactive polymers) for the conversion of mechanical energy—in this case wave power—into electrical power.

LLNL 3-D printed biocatalytic polymer turns methane to methanol at room temperature and pressure

Green Car Congress

Using particulate methane monooxygenase (pMMO), the researchers created a biocatalytic polymer material that converts methane to methanol. The enzymes retain up to 100% activity in the polymer construct. Remarkably, the enzymes retain up to 100 percent activity in the polymer. a) Schematic of PEG-pMMO hydrogel fabrication.
