A plant that can recycle uranium dioxide from nuclear fuel fabrication incinerator ash is being built in Richland, USA.
The technology uses super-critical carbon dioxide (SC CO2) to dissolve and recover the metal, rather than organic solvents and aqueous acids, reducing the volume of second generation toxic waste effluent.
Space is running low for landfill sites, and decreasing sources of minerals and metals are conflicting with projected high demands in the future. Exploring old landfills for reusable resources is therefore becoming more appealing, but can incurr high costs.
UK researchers hope to produce a novel solid-state Raman laser using a new low birefringence synthetic chemical vapour deposition (CVD) diamond. The material will produce laser with a broader optical spectrum for applications in underwater, medical and multi-spectral imaging.
High-power laser targets that incorporate single-crystal chemical vapour deposition synthetic diamond have been developed by UK scientists. The behaviour of diamond under the extreme pressures of laser beam shocks is being observed for research into new forms of energy generation such as inertial confinement fusion (ICF) energy.
Researchers in Italy are using neutron detectors made from synthetic diamond in nuclear fusion experiments. Synthetic single-crystal diamond-based detectors offer high radiation
hardness, band-gap, carrier mobility and breakdown voltage, and a low atomic number.
A prototype organic upconversion display panel that is transparent and bendable has been developed by researchers in Germany. This technology could be used to create digital newspapers, rollable television screens or ultra-lightweight laptops.
A UK consortium has announced the development of its first generation of high performance composites made from natural renewable fibres such as hemp and flax, with polypropylene and polylactic acid. The COMBINE project could help create more environmentally friendly structural components in the transport, medical and construction sectors, say researchers.
Applying surface-enhancing coatings to carbon fibre reinforced polymers (CFRP) using thermal spray techniques is the focus of research at TWI in Great Abington, UK. This could extend the use of these materials in high temperature or corrosive environments.
