WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

Researchers at Washington University in St. Louis have discovered a new way to train microbes to make n -butanol. Here we have harnessed the power of microbes to convert carbon dioxide into value-added multi-carbon compounds in a usable biofuel. We hope that it can be a steppingstone for future sustainable solar fuel production.

Study links PM2.5 pollution to increased risk of diabetes; even low levels pose risk

Green Car Congress

A study by a team from Washington University School of Medicine in St. Louis and the Veterans Affairs (VA) St. Louis Health Care System links PM 2.5 pollution—even at levels deemed safe—to an increased risk of diabetes globally. Previous studies have found that PM 2.5 Bowe, Benjamin et al.

Inorganic mercury converted to more toxic and bio-accumulative monomethylmercury in ocean waters, possibly by microbes

Green Car Congress

Lehnherr found that the relatively harmless inorganic mercury was converted, through methylation, into the neurotoxin monomethylmercury. Louis, Holger Hintelmann, Jane L. For the study, Lehnherr’s research group incubated seawater samples, collected from the Canadian Arctic Archipelago, with stable inorganic mercury.

PNNL-led team designs highly active cobalt-based PGM-free catalyst for fuel cells

Green Car Congress

They then used high-temperature pyrolysis to convert the atoms to catalytically active sites within the framework. Along with PNNL, researchers from Washington University in St. A two-step encapsulation and ligand-exchange approach effectively introduces CoN 4 complexes into the ZIF-8 micropores. —Yuyan Shao.
