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

Green Car Congress

A team led by the University of Alberta has confirmed that inorganic mercury (Hg) found worldwide in ocean water is transformed into monomethylmercury (MMHg)—a potent and bio-accumulative neurotoxin—in the seawater.

University of Wisconsin seeking commercial partners for alkylphenol solvent-based method to convert biomass into furan derivatives for fuels and chemicals

Green Car Congress

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners for a novel, cost-effective method developed by University of Wisconsin, Madison researchers for producing furan derivatives such as hydroxymethylfurfural (HMF), furfural, levulinic acid (LA) or γ-valerolactone (GVL) from biomass using alkylphenols as solvents.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The advancement could significantly boost the production of hydrogen from sunlight by using the cell to split water at a higher efficiency and lower cost than current photoelectrochemical approaches. Beard and other NREL scientists in 2011 published a paper in Science that. The research is outlined in a paper in Nature Energy.

Expansion of sugarcane crop in Brazil to areas previously occupied by crops or pastureland leads to local cooling

Green Car Congress

It does so by reflecting sunlight back into space and by lowering the temperature of the surrounding air as the plants “exhale” cooler water. They measured temperature, reflectivity (albedo), and evapotranspiration—the water loss from the soil and from plants as they exhale water vapor. —Scott Loarie.
