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…
As new types of water contaminants continue to emerge, such as retinoids and endocrine-disrupting chemicals, wastewater-treatment techniques are evolving to economically handle them. One new process that has shown promise against both conventional and emerging water pollutants integrates two technologies…
Li2CO3 from brine Purities of greater than 99.9% for battery-quality lithium carbonate have been achieved using a proprietary artificial-intelligence-powered crystallization technology developed by Standard Lithium Ltd. (Vancouver, B.C.; www.standardlithium.com). The total cation contaminant levels were reduced from nearly 2,500 parts…
Anellotech (Pearl River, N.Y.; www.anellotech.com) recently announced a successful laboratory demonstration of a process to convert mixed plastic waste into a host of useful starting materials for new plastics. The process (diagram), known as Plas-T-Cat, would take place in a…
An international team, led by Mahdokht Shaibani from Monash University (Melbourne, Australia; www.monash.edu), has developed an ultra-high capacity lithium-sulfur battery with better performance and lower environmental impact than current Li-ion batteries. The team includes people from Monash University, University of…
Everactive (Charlottesville, Va.; www.everactive.com) has just launched its Machine Health Monitor (MHM) product for batteryless vibration and temperature sensing of process machinery (photo). The MHM harvests waste energy from small temperature differentials (10°F or greater) and ambient light (100 lux…
An alternative method for processing mixed nickel-cobalt hydroxide precipitate to separate the nickel from cobalt and manganese has been proposed by a team from the Bandung Institute of Technology (Bandung, Indonesia; www.itb.ac.id), the Indonesian Institute of Sciences (Bandung) and the…
Researchers from Indonesia’s Bogor Agricultural University (Bogor, Indonesia; www.ipb.ac.id), the University of Bath (U.K.; www.bath.ac.uk), and the University of Johannesburg (Johannesburg, South Africa; www.uj.ac.za), led by Budi Riza Putra, have developed a low-cost, low-energy and low-maintenance, solar-powered desalination system that…
