Porous Materials. (Group website here) Our current focus is to develop the patented Lost Carbonate Sintering (LCS) process for manufacturing porous metals, to study the mechanical, thermal, electrical, acoustic and biological properties of porous metals and metal matrix syntactic foams, and to explore their feasibility for applications in energy, automotive, defence, aerospace, building and biomedical industries. Current Research Projects Micro-porous copper for thermal management Micro-porous titanium for biomedical applications Acoustic properties of micro-porous metals Mechanical properties of LCS porous metals Metal matrix syntactic foams for energy absorption Y.
