The startup company RenewCO2 (Piscataway, N.J.; www.renewco2.com) has developed a catalyzed electrochemical process for selectively producing monoethylene glycol (MEG) in a single step using byproduct carbon dioxide from other processes as feedstock. MEG is important industrially because it is the…
Magnesium metal is important for several emerging potential sustainability-related applications, including carbon capture, low-carbon cement and energy storage. These potential applications are driving efforts to efficiently produce magnesium hydroxide, the raw material for manufacturing Mg metal. It is possible to…
Catalysts by AM In late September, BASF SE (Ludwigshafen, Germany; www.basf.com) introduced X3D, a new additive-manufacturing (AM; 3D printing) technology for shaping catalysts. Catalysts produced with this technology feature an open structure, resulting in a reduction of the pressure drop…
Scientists at the U.S. Dept. of Energy’s Brookhaven National Laboratory (BNL; Upton, N.Y.; www.bnl.gov) and collaborators at Cold Spring Harbor Laboratory (CSHL; Laurel Hollow, N.Y.; www.cshl.edu) have genetically engineered a strain of duckweed (Lemna japonica) to produce high yields of…
Hollow silica particles (HSPs) are materials of interest for thermal insulation applications because of their very low thermal conductivity, but the particles pose health hazards and the powder is impractical to use, so scientists have been trying to incorporate HSPs…
Last month, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced NextGen Pelletizing — a visionary concept for the next generation of iron-ore pelletizing plants that strive to be carbon neutral and autonomous. According to the company, the combination of innovations —…
Electrochemically reducing carbon dioxide to carbon monoxide offers a pathway to use CO2 as a feedstock, but the reaction is challenging because it requires catalyst molecules and dissolved CO2 to meet on the electrode surface. One approach to help this…
Organic-solvent nanofiltration (NF) uses membranes with tiny pores to remove dissolved molecules. “Although NF is more energy efficient than alternative separation methods, such as distillation, the majority of polymer-based membranes exhibit poor chemical stability,” says Rifan Hardian, a post-doctoral researcher…
For the first time, researchers have proven that multigene bioengineering of photosynthesis increases the yield of the major food crop soybean in field trials. An international collaborative team of the RIPE project (Realizing Increased Photosynthetic Efficiency), led by the University…
Researchers from Chung-Ang University (Seoul, South Korea; https://neweng.cau.ac.kr) have developed a triboelectric nanogenerator (TENG) that is operable via breathing and can, therefore, be integrated into gas masks. The device is capable of powering LEDs and Bluetooth trackers, and can monitor…
