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. In the estuary ecosystem paper, led by post-doctoral scholar Samreen Siddiqui, the model organisms were Inland Silverside and mysid shrimp.

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. The new work by Cao et al.
