Cleaning up mine water seepage

A team from the Clean Environment Management Centre, University of Teesside, UK, has successfully extracted ochre - a red/yellow clay earth pigment - from a stream running through Skinningove, north of Whitby. The 'Red River' is the legacy of mine water seepage from disused ironstone mines. The filtered ochre could be suitable for cement manufacture, as recording material in CDs, and as a pigment in pottery and concrete products.

Uranium deal signed

Australia has signed a trade agreement with China for the supply of uranium, which offers the opportunity for the country to double its current export volumes. China is looking to import around 20,000 tonnes of uranium annually by 2015. A nuclear safeguards agreement was part of the deal.

Smart thermal barrier coatings for gas turbines

Southside Thermal Sciences (STS) Ltd, London, UK, plans to begin final trials of its 'smart' thermal barrier coating (TBC) for online non-destructive inspection of gas turbines used in power generation and aircraft. The coating works by embedding the ceramic surface with rare earth ions that have a phosphorescent response under excitation light and will reveal information about temperatures at the surface and subsurface of the coating, as well as erosion and changes of phase composition.

Innovations in plastics - the ANTEC conference

More than 700 technical papers were presented at the Society of Plastics Engineers' ANTEC conference, held in Charlotte, South Carolina, in early May 2006. Topics covered included nanomaterials and the modification of polyolefins.

New nano learning opportunities

University College London, UK, launched a Nanotechnology MSc course in September 2006. The course will focus on various areas of nanotechnology, including physical science, nanoscale processing and characterisation, experimental techniques, business aspects, nanoelectrical devices and quantum computation and communication.
