MOFs and nanochannels enable lithium extraction from brines
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…

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…
Conversion of plastic packaging to BTX and olefins is demonstrated
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…
Progress towards lithium-sulfur batteries
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…
Batteryless machine-health monitor enabled by low-power computer chips
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…
Oxidative precipitation recovers nickel and cobalt from ore
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…
A desalination process that pumps ions instead of water
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…
This gold catalyst improves CO2 reduction
Researchers from the Korea Advanced Institute of Science and Technology (KAIST; Daejeon; www.kaist.ac.kr) have developed a three-dimensional (3D) hierarchically porous nanostructured catalyst that is said to have a CO2-to-CO conversion rate up to 3.96 times higher than that of conventional…
Semiconducting material combines handedness and polarity
A semiconducting material synthesized by researchers at Rensselaer Polytechnic Institute (RPI; Troy, N.Y.; www.rpi.edu) could enable new ways of manipulating electronic materials remotely using light. The material, explains RPI professor of materials science and engineering Jian Shi, derives its unique…
Wood-supported catalyst safely keeps fruit fresh
Ethylene is a multifunctional phytohormone that regulates growth, ripening and other functions in plants. For example, bananas stored next to apples will ripen quickly due to the ethylene released from the apples, which in turn are triggered to release more…
