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.

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.

Study Finds Availability of Low-CO2 Electricity and Hydrogen May Paradoxically Delay Large-Scale Transition to Electric and/or Hydrogen Vehicle Fleet

Green Car Congress

Increased availability of low CO 2 sources of electricity and hydrogen could counter-intuitively delay, rather than accelerate, a large-scale transition to an electric and/or hydrogen vehicle fleet, according to a new study by researchers from Ford Motor Company and Chalmers University of Technology in Sweden.

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

Green Car Congress

Researchers at the University of Exeter (UK) have developed a novel p-type LaFeO 3 photoelectrode using an inexpensive and scalable spray pyrolysis method. Cost effective solar fuel generation is hindered by the semiconductor material not meeting certain essential criteria to achieve highly efficient solar to hydrogen conversion.
