Phase Separation of PMMA and PS on Si wafer @Muslimun

KH O The video shows the dewetting process of the PS polymer layer on Si wafer as PMMA layer (above the PS) is trying to wet the Si wafer after annealing above Tg (around 103c) The Star shape is a defect created to observe the effect of nucleation dewetting and/or spinodal dewetting.

Simple Handheld Wireless Induction Magnetometer Sensor (micro/Nano powder)

KH O 2011-08-22 | The video shows a simple design of a handheld wireless induction magnetometer sensor capable of sensing magnetite nanopoweder. It was part of my final project in the MSc of Nanotechnology course in the University of Sheffield. Feel free to message me if you need further information
