Researchers from the Dept. of Chemical Engineering, Monash University (Clayton, Victoria, Australia; www.monash.edu), have reported on a new composite polymer hydrogel with light-absorbing particles incorporated within it, that can be used as draw agents in the forward osmosis (FO) process…
A challenge in recovering fissile material from spent nuclear fuel is separating radioactive components that cannot be reused as fuel. Researchers at Sandia National Laboratory (Albuquerque, N.M.; www.sandia.gov) have fabricated metal-organic frameworks (MOFs) capable of selectively capturing gaseous iodine from…
A technique for protecting structural steel from fire using the endothermic decomposition of magnesium hydroxide has been developed by a team from the Dept. of Chemical Engineering and Materials Engineering, the University of Auckland (New Zealand; www.auckland.ac.nz). Led by professor…
Outotec Oyj (Espoo, Finland; www.outotec.com) has introduced a new partial roasting process to purify copper and gold concentrates that are contaminated with arsenic, antimony and carbon. The process is a pretreatment stage for Cu- and Au-extraction plants, and enables the…

A carbothermal process for obtaining magnesium — developed by CSIRO (www.csiro.au) Light Metals Flagship (South Clayton, Victoria, Australia) — overcomes previous limitations to commercial viability. For several years, magnesium has been produced mainly by electrolytic routes, from magnesium chloride sources…
