Georgia Tech prototype triboelectric nanogenerator could extract energy from ocean waves

Green Car Congress

Researchers at Georgia Tech have developed an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy from ocean waves by making use of contact electrification between a patterned plastic nanoarray and water. A report on their work is published in the journal Angewandte Chemie. —Lin et al.

Enzymatic Process Converts Cellulosic Materials and Water into Hydrogen at Low Temperature; Close to Theoretical Yield of H2 From Glucose

Green Car Congress

Researchers at Virginia Tech, Oak Ridge National Laboratory (ORNL), and the University of Georgia have produced hydrogen gas in a spontaneous, “one-pot” process using an enzyme cocktail, cellulosic materials from non-food sources, and water. Hydrogen production from cellodextrin and water by a synthetic enzymatic pathway.

It is produced via a microbial process called denitrification, which converts nitrogen to nitrous oxide and an inert gas called dinitrogen. Human activities, including fossil fuel combustion and intensive agriculture, have increased the availability of nitrogen in the environment. Beaulieu et al. PNAS doi: 10.1073/pnas.1011464108.

Roadmap shows how to improve lignocellulosic biofuel biorefining with high-value products from isolated lignin

Green Car Congress

The resulting roadmap uses the integration of genetic engineering with analytical chemistry tools to tailor the structure of lignin and its isolation so it can be used for materials, chemicals and fuels, said lead author Arthur Ragauskas, a professor in the School of Chemistry and Biochemistry at the Georgia Institute of Technology.
