Upcycled silicon improves LIB energy storage

Silicon is seen as a promising alternative to graphite in lithium-ion battery (LIB) anodes, due to its abundance and higher energy-storage capability — silicon is said to store ten times more energy than graphite in LIB applications. However, manufacturing processes…

New fabrication method for fluorine-containing carbon-capture membranes

Recent work by a team of researchers from Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) and the University of Tennessee (Knoxville; www.utk.edu) has brought cost-effective, fluorinated carbon molecular-sieve membranes within closer reach. To make the membrane, the researchers…

A new approach makes flexible screw pumps

Leistritz Pumpen GmbH (Nuremberg, Germany; www.leistritz.com) has recently introduced Flexcore, the first screw pump capable of adapting to a wide range of installation situations. “With Flexcore, Leistritz has now created a globally groundbreaking innovation — a pump class that, for…

A steam-stable MOF for high-capacity carbon capture

A recently discovered family of highly porous metal-organic framework (MOF) materials is showing promise in carbon-capture applications. Researchers from University of California, Berkeley (www.berkeley.edu), Lawrence Berkeley National Laboratory (LBL; www.lbl.gov) and ExxonMobil Corp. (Irving, Tex.; www.exxonmobil.com) demonstrated the efficacy of…
