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.

UGA study links heavy-metal contamination to antibiotic resistance

Green Car Congress

Using a process known as genomic analysis, University of Georgia scientists have found a strong correlation between antibiotic resistance and heavy metal contamination in an environment. But antibiotics aren’t the only source of selection pressure. Human activities like agriculture and the combustion of fossil fuels play a role.

Three-layer technique helps secure additive manufacturing

Green Car Congress

Researchers from the Georgia Institute of Technology and Rutgers University have developed a three-layer system to verify that components produced using additive manufacturing have not been compromised. —Raheem Beyah, Georgia Tech. The technique will also be applied to additional types of printers, and to different materials.
