AEMSLab Materials Projects
Thin Film Materials
Thin film materials may actually define our technology age. Electronics, processors, sensors, communications, medical equipment... thin film devices are the difference between us and the past. In a strange irony, thin film materials are manufactured using some of the most dangerous chemicals and most energy intensive processes. Thin film solar cells based on GaAs require two of the most deadly reactive gasses that humans have ever developed for their manufacture.
Is it possible to manufacture thin film materials and devices without toxic precursor materials and with low energy requirements?

The AEMS Lab gets a new world-class facility!
A major research funding grant has been awarded to the AEMSLab for collaboration with Prof. J-S Wu's numerical modelling group in Taiwan. The FRST research grant was awarded in 2007 and will carry through 2011. The grant was for $891,000 and support a post-doctoral researcher, PhD students, a Masters student and a Final Year Project team.

Hypersonic Heat Shield Coatings
Dr. Krumdieck has been invited to participate in the National Hypersonic Science Research Center in the USA. The NHSC is funded by NASA and the US Air Force Office of Research and is a consortium of 8 top US Research Universities plus space contractor, Teledyne. The researchers are investigating different aspects of the enabling science for hypersonic vehicles. The types of materials, structures and controls for vehicles that could travel 10 times the speed of sound are not known. The aim of the NHSC is to advance the science enough to enable the technology. Dr. Krumdieck's role is to look at making high temperature and oxygen protection coatings for the structural components. At this time the materials of interest are SiC/SiC composites for the structure and coating of mullite (alumina silicate ceramic) on the ceramic matrix composite (CMC) structure.

NEW Commercialisation Funding for Industrial Wear Coatings
Pre-Seed Accelerator Fund (PSAF) funding from FRST has been awarded for a 6-month development project. The objective is to develop a protective ceramic coating for complex 3-D shaped metal components. The first target application is a wear protection coating for stainless steel water pumps. In most applications sand, volcanic ash or other particles are present in well water. These particles are harder than stainless steel so erode the impellor blades, reducing pumping energy efficiency and reducing service life. Alumina coatings are harder than silica sand, so will increase service life.
The Research Grant value is $94,763
