OSU researchers find small particles from tires inhibit growth of organisms in freshwater, coastal estuaries

Green Car Congress

Small particles from tires inhibit the growth and cause adverse behavioral changes in organisms found in freshwater and coastal estuary ecosystems, according to two new Oregon State University studies. Both organisms had reduced growth depending on the level of exposure to micro tire particles. Credit: John Dickens.

Tohoku, UCLA team advance 4V-class metal-free organic Lithium-ion batteries; croconic acid cathode

Green Car Congress

A joint research team from Tohoku University and the University of California, Los Angeles (UCLA) has made a significant advance towards high-voltage metal-free lithium-ion batteries by using a small organic molecule: croconic acid. Increasing organic batteries’ voltage could lead to higher energy-density batteries.

Penn team proposes liquid-organic hydrogen carriers as endothermic fuels for hypersonic aircraft

Green Car Congress

A team at the University of Pennsylvania is proposing the use of a liquid-organic hydrogen carrier (LOHC)—specifically, 1,2,3,4 -tetrahydroquinoline (THQ)—for use as an endothermic fuel for thermal protection of hypersonic aircraft engines. A paper on their work is published in the journal Fuel. earlier this year.

Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

A team of scientists from six institutions, including Akihiro Moriyoshi, Emeritus Professor Hokkaido University, have found that the presence of Trace Quantities of Organic Matter (TQOM) in modern concrete structures and asphalt pavements drive the deterioration of these structures.

New organic cathode for high performance solid-state sodium-ion battery

Green Car Congress

Researchers at the University of Houston have now developed an organic cathode that improves both stability and energy density. The flexibility of the organic cathode allowed it to maintain intimate contact at the interface with the solid electrolyte, even as the cathode expanded and contracted during cycling. —Yan Yao.
