Ceramic filter to reduce greenhouse gases

A ceramic material that can filter oxygen from the air could be used to reduce greenhouse gas emissions from power stations.

Minerals mapping tool trialled

A novel automated minerals mapping tool is undergoing its first long-term trial at Rio Tinto's Pilbara iron mining operation in the Hamersley province of Western Australia. The Fe (Iron) Hylogger provides data on ore samples for exploration and 3D models.

Optical fibres for crack detection in composites

Optical fibres may one day aid crack detection in composite structures, says Jasson Gryzagoridis a Professor of Mechanical Engineering at the University of Cape Town, South Africa. Exsisting non-destructive techniques are not entirely effective.

Next-generation self-healing polymers

The next generation of polymers that repeatedly self heal are on their way, according to scientists at the University of Illinois at Urbana-Champaign, USA. By introducing a 3D microvascular network to the ductile epoxy substrate, emulating biological circulatory systems, researchers have attempted to create a renewable delivery mechanism for the DCPD monomer to extend the life of materials. The structure is fabricated using a direct-write assembly technique developed by Professor of Aerospace Engineering Scott White, and Professor of Materials Science and Engineering Jennifer Lewis.

Carbon nanotubes for neural engineering

Scientists at the NASA Ames Research Center, Moffett Field, USA, have developed vertical free-standing carbon nanofibres for use in neural-electrical interfaces. These could improve implantable biomedical devices for managing Parkinson’s disease, epilepsy and depression.
