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.

UW Madison chemists discover new way to harness energy from ammonia

Green Car Congress

A research team at the University of Wisconsin–Madison has identified a new way to convert ammonia to nitrogen gas through a process that could be a step toward ammonia replacing carbon-based fuels. For a fuel cell, we want an electrical output, not input. This is the first process, as far as we know, to do that.

Researchers Show New Piezeoelectrochemical Effect Can Scavenge Energy Wastes Such as Noise or Vibration to Generate Hydrogen Via Water Splitting

Green Car Congress

H 2 and O 2 are produced by deforming a ZnO fiber or BaTiO 3 dendrite in water via oxidation-reduction reactions. Materials scientists at the University of Wisconsin-Madison have discovered a phenomenon—the direct conversion of mechanical energy to chemical energy—which they termed the piezoelectrochemical (PZEC) effect.

UW-Madison team develops more streamlined, cost-effective process for conversion of biomass to liquid hydrocarbons via a GVL pathway

Green Car Congress

A team at the University of Wisconsin-Madison led by Dr. James Dumesic has developed an improved, streamlined process for the conversion of biomass to butyl esters and γ-valerolactone (GVL). Dumesic and his colleagues had earlier reported on the conversion of GVL to gasoline, jet and diesel fuel components. Resources.
