A cheap but effective polymeric coating to repair damaged aircraft wires and prevent them from sparking and causing an explosion is available, says a chemist at the University of Dayton Research Institute, USA.

Fullerene solutions to chip manufacture

Materials World magazine
A water-soluble fullerene resist for lithography could make electronics manufacturing safer and more environmentally friendly by removing the need for toxic and flammable solvents. Using the resist, a team at the University of Birmingham, UK, has demonstrated a high resolution of about 30nm for the transfer of integrated circuit patterns onto silicon wafers and a strong durability to etching of these substrates.

Inspecting textured ceramic tiles

Materials World magazine
Dynamic Photometric Stereo (PS) is new approach to inspect fast moving, difficult to analyse surfaces, such as glazed or textured ceramic tiles. It allows manufacturers to produce images of complex 2D and 3D features or flaws, and reduce waste caused by defective tiles.

A sulphide reduction process (SRP) that enables ‘fast and cheap’ extraction of gold from sulphide ores is available from Haber Inc, based in Arlington, USA.

Dispersing functional fillers in polymers

Materials World magazine
Polyfect, a spin-out company from Loughborough University, UK, hopes to license a technology for dispersing functional fillers to improve the mechanical quality and reduce the weight and cost of polymer products, which could benefit applications such as automotive, packaging and electronics.
