DuPont (Wilmington, Del.) announced it has signed an agreement to acquire Donatelle Plastics Incorporated, a leading medical-device contract manufacturer specializing in the design, development and manufacture of medical components and devices. The transaction is expected to close in the third…
Conventional bioprocesses use three separate steps to convert cellulose into products, such as bioplastics and biofuels. The consolidated bioprocess (CBP) combines all steps — cellulase production, cellulose hydrolysis and product fermentation — in a single reactor. Using the natural abilities…
Researchers at Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) and a team of interdisciplinary scientists tripled the yield of methanol in the catalytic hydrogenation reaction of carbon dioxide by introducing hydrides into the catalyst support material. The researchers…
An Oak Ridge National Laboratory (ORNL) team created and tested two different formulations for stationary batteries that could utilize CO2 from industrial sources while storing energy from wind turbines and solar panels. Consisting of two electrodes in a saltwater solution,…
Traditionally, many polymerization reactions are carried out batchwise in reactor vessels, with the reaction taking place in solution, emulsion or in a melt. This procedure reaches its limits if, for example, the reaction is very exothermic or the viscosity increases…
In a first-of-its-kind trial project, a CO2-removal method known as enhanced rock weathering (ERW) is being combined with biotechnology to accelerate atmospheric CO2 sequestration. FabricNano (London, U.K.; www.fabricnano.com) and Veolia (Paris, France; www.veolia.com) have embarked on a partnership wherein enzymes…
Calcium-sulfonate complex greases are widely used in applications in the pulp-and-paper, marine and steel-manufacturing sectors. Within an ever-volatile lithium market, calcium-sulfonate greases are increasingly seen as a reliable alternative to lithium-based greases. However, typical methods for preparing high-performance calcium-sulfonate grease…
