Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

This one-step nitrogen-fixation strategy to produce ammonia is eco-friendly and low cost, which converts widely available starting materials into a value-added product. To break nitrogen’s strong bonds, the Haber-Bosch process requires roughly 80-300 atmospheres of pressure and temperatures around 572-1000 ˚F (300-500 ˚C).

Chinese researchers develop novel aluminum–graphite dual-ion battery

Green Car Congress

A team from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has developed a novel, environmentally friendly low-cost battery. Compared with conventional LIBs, this battery (AGDIB) shows an advantage in production cost (~ 50% lower), specific density (~1.3-2.0 and Lee, C.-S. Energy Mater.

New aluminum-cerium alloys could boost rare earth production; improved energy efficiency of engines

Green Car Congress

The evidence suggests that as much as 25% to 30% of the existing titanium market (4000 t annually) is driven by temperature performance in the 150 °C to 315 °C range, which is within the expected operating range of this alloy system. This intermetallic melts only at temperatures above 1093 ˚C (2,000 ˚F). —Sims et al. McCall, M.
