The Surface Science of Vacuum Glazing. In order to achieve a stable vacuum in evacuated glazing, high temperature baking during evacuation is required. The high temperature processing prevents the use of strengthened glass, such as tempered glass. However, samples made at low temperatures suffer from poor vacuum characteristics, particularly when exposed to UV radiation. In this project, we aim to discover the chemical and physical processes occurring on the glass surface responsible for vacuum ....The Surface Science of Vacuum Glazing. In order to achieve a stable vacuum in evacuated glazing, high temperature baking during evacuation is required. The high temperature processing prevents the use of strengthened glass, such as tempered glass. However, samples made at low temperatures suffer from poor vacuum characteristics, particularly when exposed to UV radiation. In this project, we aim to discover the chemical and physical processes occurring on the glass surface responsible for vacuum degradation. We will use this knowledge to develop a low temperature manufacturing process that can be used with tempered glass and results in a high-quality vacuum, stable over the device service life.Read moreRead less
Pulsed oscillating mass analyser. Mass spectrometers are ubiquitous components in chemical analysis, but are often large and expensive. We have developed a new method for mass analysis, which is smaller and cheaper than existing technology. However, the analyser needs further research to determine whether it has the performance specifications to match the other technologies. The objective of this research is to characterise, explore and extend the prototype and to develop the appropriate math ....Pulsed oscillating mass analyser.

Manufacture of optical thin film coatings is a difficult and generally inefficient process undertaken within a vacuum chamber. There are many variables which are not easily controlled nor understood in these complex thermodynamic environments.
