Heap-leaching for REs Studies conducted by Texas Rare Earth Resources Corp. (Sierra Blanca, Tex.; www.trer.com) indicate that heap leaching with 15% (~150 g/L) sulfuric acid has the potential to dissolve minerals containing rare-earth (RE) elements from host rock at…
The Circa Group (Melbourne, Australia; www.circagroup.com.au) and the Green Chemistry Center of Excellence at the University of York (U.K.; www.york.ac.uk) have signed an agreement to develop and commercialize a novel “green” solvent called Cyrene. Cyrene is a polar aprotic solvent…
Although several antimicrobial hydrogels have been developed in recent years, they all have one or more drawbacks, such as possible toxicity, insufficient stability and biodegradability, and high costs. These and other drawbacks have been overcome with a synthetic hydrogel being…
The first commercial application of a newly developed process for the treatment of oxides of nitrogen (NOx) waste gas has been established at a milling operation in Los Angeles, Calif. Developed by Pacific Rim Design and Development (PRDD; Reno, Nev.;…
Last month, Air Products (Allentown, Pa.; www.airproducts.com) announced that it has licensed its proprietary adsorption-based, monomer recovery process to custom process equipment supplier Cryo Technologies (Allentown, Pa.; www.cryotechnologies.com). The hybrid Air Products technology combines a partial condensation unit with a…
Detection of extremely small quantities of dangerous or hazardous substances is important in many areas, including national security, safety of public utilities and radiation prevention. Several analytical methods have been developed using structural, functional and electronic properties of nanomaterials. In…
A new and inexpensive way to produce TiFe — an alloy with potential as a material for reversibly storing hydrogen — has been developed by the research groups of professors Zenji Horita and Etsuo Akiba at Kyushu University (Fukuoka, Japan;…
Capacitive desalination, in which salt ions are electrically removed from saltwater, has been researched for decades as a potentially cheaper alternative to energy-intensive reverse osmosis (RO) and distillation, but so far its application has been limited to waters with very…
An Australian team has developed a structure made of a metal organic framework (MOF) that captures and then releases CO2 using natural sunlight. The team includes researchers from: CSIRO Division of Materials Science and Engineering, (Clayton South, Victoria; www.csiro.au) the…
Biosteel The worlds first artificial-silk fiber that is entirely made of recombinant spider-silk proteins has been produced by AMSilk GmbH (Planegg/Martinsreid, Germany; www.amsilk.com), a spin-off company of the Technical University of Munich. The fibers tensile strength is comparable to…
