U Michigan team develops air-stable catalyst for upgrading ethanol to 1-butanol

Green Car Congress

Researchers at the University of Michigan have developed an le air-stable amide-derived N,N,N-Ru(II) complex to catalyze the conversion of ethanol to 1-butanol with high selectivity. The researchers report that conversion to upgraded products exceeds 250 turnovers per hour (>50% conversion) with 0.1 Wingad, Paul J.

UGA team develops method for genetic engineering of Caldicellulosiruptor thermophilic bacteria; another pathway for efficient conversion of biomass to fuels and chemicals

Green Car Congress

Current methods for the use of lignocellulosic biomass as a substrate for microbial conversion to products of interest rely on pretreatment of the biomass with acids, alkali or organic solvents, often at high temperature and the addition of hydrolytic enzymes that partially digest the plant cell walls.

U Michigan team boosting efficiency of thermoelectric materials; potential of reaching 15-20% efficiency could result in practical applications

Green Car Congress

But we did not know what features we could manipulate to maximize the conversion of heat into electricity. In this paper, we propose that certain configurations of the filler element barium will be very effective in lowering the materials’ thermal conductivity and thus increasing their conversion efficiency.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Overall, a conversion to battery-powered electric rideshare fleets could reduce the costs to society by 3-11% per trip, depending on the cost assigned to greenhouse gas emissions, the researchers say. Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. 2c07030
