Graphene covers an infrared screen, enhancing its signals

Creating large graphene coatings

Graphene films that can be deposited over large areas of a substrate may be possible using modified chemical mechanical polishing, according to scientists in the USA. The material’s perfect 2D crystallographic nature and electrical properties will enable high-speed and flexible circuitry in electronic devices.

Radioactive recycling of uranium

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.

Finding gold in garbage?

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.

Taking the strain out of lasers

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.

Target practice for synthetic diamond

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.
