Microbial electrolysis produces hydrogen from organic waste
A modular, fuel-cell-like assembly featuring specially developed microbial communities is capable of producing pure hydrogen from a wide range of organic wastes. Developed by startup company Electro-Active Technologies (Oak Ridge, Tenn.; https://electroactive.tech), the microbial electrolysis system is now in the…
Bowl-shaped electrode enhances CO2 reduction
An international group of scientists has created a bowl-shaped electrode that can efficiently convert CO2 into carbon-based fuels and chemicals. The group includes scientists from the University of Bath (Bath, UK; www.bath.ac,uk), Fudan University (Shanghai, China; www.fudan.edu.cn), and the Shanghai…
Pilot plant slated for a H2-based process to make DRI from iron-ore fines
The use of direct reduced iron (DRI; sponge iron) and hot briquetted iron (HBI) is expected to continue to grow due to the need to reduce greenhouse gas emissions and the growing number of electric arc furnaces (EAFs) in service…
Poly-diketoenamines could allow closed-loop plastics recycling
Conventional plastics are difficult to recycle because end-of-life processing generally is either energy-intensive or alters the physical properties of the materials. A team of researchers from the Lawrence Berkeley National Laboratory (Berkeley, Calif.; www.lbl.gov) and the University of California at…
MOFs that mimic leaves for enhanced performance
Chemists from the research group of Stefania Grecea at the University of Amsterdam’s (UvA; the Netherlands; www.uva.nl) Research Priority Sustainable Chemistry have devised a way to enhance the practical performance of metal-organic frameworks (MOFs). By using leaves from the black…
Thermal insulation mimics polar-bear hair
Scientists from the University of Science and Technology of China (Hefei; https://en.ustc.edu.cn), led by professor Shu-Hong Yu, have developed a thermal insulator that mimics the structure of individual polar-bear hairs, and have scaled toward a material made of many hairs.…
A solvent-extraction approach for desalination of high-salinity brines
Hypersaline industrial wastewater brines are difficult to treat. Current approaches for removing salt from such brines — such as evaporative distillation and reverse-osmosis (RO) — are problematic because evaporation is highly energy-intensive and RO cannot handle salt levels present in…
European project aims to develop CCS technology on an industrial scale
Last month, a consortium of 11 European partners, including ArcelorMittal, Axens, IFP Energies nouvelles (IFPEN) and Total, launched a project to demonstrate an innovative process called DMX for capturing CO2 from industrial activities. It is part of a more comprehensive…
Sound solutions to low-frequency noise
Low-frequency noise (≤500 Hz) from various sources, such as construction machinery and aircrafts, is a form of noise pollution that transmits over long distances and disturbs the surrounding area. It is also known to trigger several negative physiological reactions, such…
Selectively perform cross-coupling reactions with this catalyst
Twofold C–H activation and cross-coupling of stoichiometric amounts of organic molecules, R1–H and R2–H, to form an R1–R2 product that is free of homocoupling products (R1–R1 or R2–R2) is a goal to simplify organic synthesis of certain compounds. Up to…
