Manufacture and Characterisation of Porous Materials. (Group website here) Our current focus is:
Ø to develop the patented Lost Carbonate Sintering (LCS) process for manufacturing porous metals,
Ø to study the mechanical, thermal, electrochemical and acoustic properties of porous metals and metal matrix syntactic foams, and
Ø to explore their feasibility for applications in energy, automotive, defence, aerospace and building industries.
The LCS technology has been licensed to Versarien plc, a high-tech start-up company founded in 2010 to commercialise the LCS process for micro-porous copper in thermal management applications. Versarien was floated on the London Stock Exchange in June 2013, with a market capitalisation of more than £15 million. Versarien has acquired Total Carbide to expand the production.
