A process (and/or catalyst) to make ultra-high molecular weight polylactide

Overview Polylactic acid (PLA) is one of the most promising kinds of bioplastics. It is a bio-sourced, degradable polymer that can be made using renewable materials and represents a crucial way to reduce our dependence on single-use plastics sourced from fossil fuels. However, there has not been an efficient way to create the ultra-high molecular weight...

Electrochemical Reduction of CO2 at Copper Nanofoam Electrodes

Overview There is currently a great deal of interest in CO2 reduction as a way to capture carbon and use it to make industrial chemicals, most of which are still being made from fossil fuels. We have invented a copper nanofoam electrocatalytic electrode that reduces CO2 10–20% more effectively than smooth electropolished copper electrodes. Market...

Nanostructured sorbent materials for capturing environmental mercury vapor (Case 1887)

Overview Mercury is a toxic pollutant that can persist in the environment and build up in the food chain. While regulations and new innovations have curtailed the use of mercury in many household items such as thermometers, it remains in use in ubiquitous products such as compact fluorescent lamp (CFL) light bulbs. Hurt et. al. have developed a solution...
