Researchers show how bacteria convert toxic copper ions to stable metallic copper

Green Car Congress

Researchers from the University of Houston, with colleagues at the University of São Paolo in Brazil, have demonstrated how copper-resistant bacterium from a copper mine in Brazil convert CuSO 4 (copper sulfate) ions into zero-valent Cu (metallic copper). An open-access paper on their research is published in Science Advances.

Rice, C-Crete team optimizes conversion of tire waste into graphene for stronger concrete

Green Car Congress

Rice University scientists and their colleagues at C-Crete Technologies have optimized a process to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete. The Rice lab flashed tire-derived carbon black and found about 70% of the material converted to graphene. After 28 days, 0.1
