Precision & Nano Processing Technologies

The Laboratory for Precision and Nano Processing Technologies is leading research in multi-scale manufacturing, cross-disciplinary characterisation of advanced materials, and multi-scale mechanics. The Laboratory has a strong international reputation for its research and innovation. The laboratory has been serving as a hub of research networking, international collaboration, and industry consultation, fostering effective solutions to production problems.  


The laboratory team was the world-first to achieve a quantitative experimental verification of the molecular dynamics prediction of Si-II phase transformation at the scale of a few nanometres. More information can be found at Nanotechnology, Vol 20, 2009, pp 305705. 

The laboratory team was the world-first to develop the damage-free and chemical-free technology for polishing monocrystalline silicon (see: Scripta Materialia, Vol 59, 2008, pp 1178-1181).
