Congratulations to Professor Liangchi Zhang, FTSE, the winner of the Science and Engineering category as well as the UNSW Inventor of the Year 2011 Award. Professor Zhang has developed a range of inventions related to the cutting and polishing of materials. The new cutting tip for the rock and coal mining industry which has a dramatically improved wear resistance compared with existing designs, reduces cutting force, energy consumption and dust generation. The silicon polishing technique is for the semiconductor industry, which produces damage-free mono-crystals silicon wafers with surface roughness less than a nanometre without
using any chemicals. The diamond polishing technique reduces the processing time in industry from about 4 hours to about 18 minutes.
