CANDU® reactor pressure tubes (PT) contain D2O, which is used as a moderator. Surrounding the PTs are gas-filled Calandria Tubes (CT), which thermally isolate the PTs from the moderator surrounding the fuel channels. If the garter springs move apart, the PT will sag into the CT. Under ... Read More

3D printing as applied to the area of electronics manufacture covers a broad range of traditional printing technologies [1]. The attraction in 3D printing lies in its potential to disrupt the traditional photolithographic/subtractive manufacturing line with simpler additive processes. ... Read More

Human body communications (HBC) uses the human body as a transmission medium to connect sensors and actuators in, on or in close proximity to the human body. The HBC approach offers tremendous potential for the design and implementation of emerging personalized healthcare systems, as ... Read More

The XENON Dark Matter Experiment utilizes ultra-pure xenon (Xe) as a target for particle interaction in the effort to detect dark matter particles. To measure the purity of Xe, a gas purity monitor (GPM) is being developed which drifts electrons through Xe gas to detect impurities that ... Read More

COMSOL Multiphysics® software is used to understand the difference in behaviour of two Magnetic Barkhausen Noise (MBN) probes. The dipole probe has to be physically rotated to sample the angular distribution of the MBN. The tetrapole probe uses vector superposition to rotate the magnetic ... Read More

This work aims to investigate the behaviour of a simple interdigital sensor structure for glucose monitoring in response to distortions in the skin-topology and differences in skin undulation during use. The study then extends to consider a flexible sensor structure which is better able ... Read More

Introduction The electrical properties of materials are important in many different applications. In microelectronics for example, films must perform as insulators, semiconductor or as conducting layers. In recent years, scanning probe methods are being extended to the nanometre scale ...

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage ... Read More

Dielectrophoresis (DEP) is an electric field driven technique that has important applications in the enrichment, concentration and isolation of biological and non-biological particles. The assessment of particle trapping capacity using DEP, however, has been qualitative in nature; since ... Read More

Insulator-based dielectrophoresis (iDEP) employs arrays of electrically insulator posts in a microfluidic device to create dielectrophoretic forces that affect particle movement (Figure 1). The trapping performance of iDEP devices involves a careful balance between electrokinetics (EK) ... Read More
