Vibrating CPD Chemical Degradation Oil Sensor
Oil analysis is a broad field comprised of hundreds of individual tests that provide meaningful benefit by assessing one or more properties of lubricants or machines. Many tests are performed on new types of oil during research and development. The lubricants chemical, physical, or lubricating …

Application of scanning micro-tip and UHV Kelvin probes in surface and material characterisation.
… the scanning Kelvin probe (SKP) for surface potential mapping and monitoring changes in work function due to environmental influences in ambient and UHV conditions. The SKP is a truly non-contact technique which determines local work function changes and surface states on conductors, …

Nanostructure Characterization, Fabrication and Devices of 2D Mos2 and Mos2/WS2 Hetrostructures
… (MoS2/WS2) are novel structures that can potentially pave the way for efficient ultrathin and flexible optoelectronics, such as light sources and photovoltaics. Such heterostructures are very rare and not much is known about their characteristics. They can only be achieved through a …

The feasibility of using electrostatic charge condition monitoring for lubricant additive screening
… and interaction between additives in tribo-contacts. The work presented in this thesis assessed whether electrostatic charge monitoring, which is sensitive to changes in surface chemistry, can offer insight into additive-surface behaviour and how this affects tribological performance. …
