Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. To determine what was happening, and the best way to make it happen, the Sandia team used computer simulations generated by coauthor Na Sai from the University of Texas at Austin that suggested which molecular changes to seek.

Rice, Lawrence Livermore scientists develop new efficient non-Pt MX2 catalyst for efficient hydrogen production; Materials Genome Initiative in action

Green Car Congress

Scientists at Rice University and the Lawrence Livermore National Laboratory have predicted and created new two-dimensional electrocatalysts—low-cost, layered transition-metal dichalcogenides (MX 2 ) based on molybdenum and tungsten—to extract hydrogen from water with high performance and low cost.

New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

Silicon nanoparticles were dispersed in a solution of phytic acid and aniline in water, followed by the addition of an oxidizer. Hydrogel primarily consists of water, which can cause lithium-ion batteries to ignite—a potential problem that the research team had to address. Batteries'

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.

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.

New metal-free ORR catalyst outperforms platinum in fuel cell

Green Car Congress

Researchers from South Korea, Case Western Reserve University and University of North Texas have synthesized new inexpensive and easily produced metal-free catalysts—edge-selectively halogenated graphene nanoplatelets (XGnPs)—that can perform better than platinum in oxygen-reduction reactions. —Jong-Beom Baek.

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. San Antonio, Texas, which, architected by Computer Terminals, was named the 8008. You’re crazy.”
