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.

Solar-to-Jet-Fuel System Readies for Take-Off

Cars That Think

Using concentrated solar energy, they were able to produce kerosene from water vapor and carbon dioxide directly from air. Syngas is produced by Fischer-Tropsch (FT) synthesis , in which chemical reactions convert carbon monoxide and water vapor into hydrocarbons. Finally, the syngas is processed to kerosene in the gas-to-liquid unit.

UBC engineers use fiber from recycled tires to develop more resilient concrete

Green Car Congress

The researchers experimented with different proportions of STF and other materials used in concrete—cement, sand and water—before finding the optimal mix, which includes 0.35% tire fibers, according to researcher Obinna Onuaguluchi, a postdoctoral fellow in civil engineering at UBC. Relative to a plain reference mixture, 0.4%

The First U.S. Human-Operated Submersible Changed the Course of Oceanography

Cars That Think

Water pressure in the deep sea makes human exploration of the ocean difficult. Air Force bomber and a tanker collided over Spain. A specially designed insulated box ensured that collected samples weren’t ruined by changes in water temperature or pressure, according to Dudley. National Oceanic and Atmospheric Administration.
