INL researchers develop high-performance oxygen electrode for PCEC cell; high-temperature electrolysis

Green Car Congress

Researchers at Idaho National Laboratory have developed a new electrode material for a protonic ceramic electrochemical cell (PCEC) that can efficiently convert excess electricity and water into hydrogen. Water splitting reaction on oxygen electrode and PNC’s hydration. The triple conducting oxide of PrNi 0.5

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

Green Car Congress

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. One way this could be achieved is by using photoelectrochemical (PEC) water splitting which directly converts water and sunlight to solar fuel (hydrogen).

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

This research article focuses on a highly favored route to the synthesis of controlled nanostructures at high rate, high yield, and low cost by molten carbonate electrolysis. A solution to this challenge is accomplished by the co-generation of a valuable product from the captured carbon, which can offset the carbon capture cost.

MIT team outlines path to low-cost solar-to-fuels devices; the artificial leaf

Green Car Congress

The new analysis follows up on 2011 research that produced a proof of concept of an artificial leaf—a small device that, when placed in a container of water and exposed to sunlight, would produce bubbles of hydrogen and oxygen. volts, is insufficient to power the water-splitting reaction, which needs more than 1.2 Earlier post.)

Mattershift scales up CNT membranes; potential for zero-carbon fuels for less than fossil

Green Car Congress

Water flow through the membranes was 1000 times higher than predicted by Hagen-Poiseuille flow, in agreement with previous CNT membrane studies. An example of a simplified schematic for converting atmospheric carbon dioxide, water, and solar or wind electricity into ethanol, gasoline, diesel, and jet fuel. McGinnis et al. Background.

How Ted Hoff Invented the First Microprocessor

Cars That Think

This article was first published as “Marcian E Hoff.” Busicom had hired Intel to develop a set of custom chips for a low-cost calculator and had sent three engineers to Santa Clara to work on the chip designs. While a research manager at Intel Corp., It appeared in the February 1994 issue of IEEE Spectrum. You’re crazy.”
