Chemists from the Swiss Federal Institute of Technology Lausanne (EPFL; Switzerland; www.epfl.ch) have developed “sponges” designed to capture various target substances, such as gold, mercury and lead, dissolved in solution. Now, they have developed one for capturing toxic hexavalent chromium…
Because of its abundance, light weight and easy alloying, magnesium metal has great potential for components in the automotive, aerospace and military industries. However, the two existing magnesium production processes — the Pidgeon process from ore and electrolytic process from…
The presence of moisture — even in very small amounts — can be extremely detrimental the manufacture of many products, including semiconductors. Removal of moisture from a contaminated process is a labor-intensive process that requires large volumes of high-purity gases.…
Although Li-ion batteries are currently the dominant technology in the rechargeable-battery sector, sodium-ion (Na-ion) batteries possess many benefits in terms of sustainability, safety and costs, and are poised to greatly expand their commercial usage. Sodium-ion battery specialist Faradion Ltd. (Sheffield,…
Scientists at the U.S. Department of Energy’s Argonne National Laboratory (Lemont, Ill.; www.anl.gov) have developed a thermal energy-storage system for industrial processes that can capture and store typically wasted heat for later use. Originally conceived as a way to store…
One of the main problems in the conversion of greenhouse gases, such as carbon dioxide and methane, into liquid fuel or hydrogen is the development of coke- and sintering-resistant catalysts. Nickel on magnesium oxide (Ni/MgO) has long been identified as…
Lithium is a key raw material for batteries that power electric vehicles, portable electronics and more, but traditional methods for obtaining it are plagued by poor lithium recovery (a large portion of Li is lost in the recovery process), slow…
Light-emitting Si Researchers from Eindhoven University of Technology (TUE; the Netherlands; www.tue.nl) have developed an alloy with silicon that can emit light. Together with researchers from the universities of Jena, Linz and Munich, the researchers combined silicon and germanium in…
Chemetry Corp. (Moss Landing, Calif.; www.chemetrycorp.com) is piloting a hybrid electrochemical-catalysis process for making propylene oxide (PO) that eliminates some of the major production hurdles associated with chlorohydrin-based PO production. “The traditional chlorohydrin process produces about 47 tons of wastewater…
A new electrochemical process could make triphenylphosphine (TPP) — an important reagent in many organic transformations — more practical for industrial use. Synthesizing TPP results in large volumes of waste in the form of triphenylphosphine oxide (TPPO), which is very…
