Selective uranium extraction

Materials World magazine
Finnish researchers claim to have found an improved solvent extraction method for uranium. The nickel producing mining company, Talvivaara in Finland, began investigations into the production of uranium as a byproduct after results revealed uranium content of 10 to15mg/l in the nickel solution.

The lowdown on low viscosity powders

Materials World magazine
A global rheological model has been developed to help predict the combined effect of shear rate, temperature and solid loading on low viscosity feedstocks used in low pressure powder injection moulding (LPIM). Producing ceramic and metal alloy parts using LPIM offers a more economical alternative to high pressure powder injection moulding (HPIM) for small series production in industries such as aerospace, medical device and automotives.
High-velocity oxyide fuel thermal spray process

Thermal spraying under control

Materials World magazine
Improving process control of thermal spray technologies to enable better application of nanostructured coatings is the aim of a research project at the University of Stuttgart in Germany. The team has created a numerical model of high-velocity oxide fuel (HVOF) and high-velocity suspension flame spraying (HVSFS).
