NEC, NEC TOKIN and Tohoku University develop spin-Seebeck thermoelectric device w/ 10x better conversion efficiency

Green Car Congress

NEC Corporation, NEC TOKIN Corporation and TOHOKU UNIVERSITY have jointly created a thermoelectric (TE) device using the spin Seebeck effect (SSE) with conversion efficiency 10 times higher than a test module that was produced based on a multi-layered SSE technology published by the Tohoku University group in 2015.

Nitrogen-doped graphene nanoplatelets offer high catalytic performance in fuel cells and solar cells; possible replacement for Pt

Green Car Congress

Researchers in South Korea have developed a simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets (NGnPs) with excellent catalytic performance in both dye-sensitized solar cells and fuel cells to replace conventional platinum (Pt)-based catalysts for energy conversion. —Jeon et al.

Modified enzyme can increase second-generation ethanol production

Green Car Congress

glucosidase and belongs to glycoside hydrolase family 1 (GH1), acts in the last stage of biomass degradation to produce free glucose for fermentation and conversion into ethanol. One of the enzyme’s advantages is that it’s produced in vitro and not from a modified fungus or other organism, so it can be mass-produced at relatively low cost.

After 50 Years, Digital Voices Speak Again

Cars That Think

And there they would have stayed without a chance conversation and assistance from some very capable librarians and archivists. Due to their low cost, thin form factor, and pliability, flexi discs became the medium of choice for magazine publishers who wished to supplement articles with audio content. Bayless, S.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

Cost effective solar fuel generation is hindered by the semiconductor material not meeting certain essential criteria to achieve highly efficient solar to hydrogen conversion. One way this could be achieved is by using photoelectrochemical (PEC) water splitting which directly converts water and sunlight to solar fuel (hydrogen).
