UMD-led study: road salts and other human sources are threatening world’s freshwater supplies

Green Car Congress

But a new study led by Sujay Kaushal of the University of Maryland warns that introducing salt into the environment—whether it's for de-icing roads, fertilizing farmland or other purposes—releases toxic chemical cocktails that create a serious and growing global threat to our freshwater supply and human health.

New catalysts enable photocatalytic version of water gas shift reaction for H2 production

Green Car Congress

Politécnica de Valencia (Spain) have found that noble metal nanoparticles supported on titanium dioxide or cerium dioxide can catalyze the industrially important water gas shift (WGS) reaction for hydrogen production at ambient temperatures using visible light irradiation. Energy Environ. Researchers at the Univ. —Sastre et al.

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. They then applied the PZEC effect to generate hydrogen and oxygen via direct water splitting. The mechanism of the water decomposition via the PZEC effect relies on the piezoelectric properties of the materials.

How Three-Season Tires Perform in Diverse Weather Conditions

The Truth About Cars

In the past, there was a push to sell all-season tires which performed at kinda-sorta acceptable levels in a variety of conditions but didn’t truly excel in any particular environment. These days, tire companies seem to be laser focused on providing consumers with rubber which is uniquely suited for the job.

RPI researchers show power generation from water flow over graphene-coated surfaces; potential for autonomous microsensors for applications in oil and gas exploration

Green Car Congress

Researchers at Rensselaer Polytechnic Institute (RPI) and Rice University led by RPI Professor Nikhil Koratkar have shown that flowing water with various molarities of hydrochloric acid (HCl) over graphene generates induced voltages an order of magnitude higher as compared to carbon nanotubes.
