This thesis examines the formation of martensite in Ni-based super-alloys in both an alloy-coating system and in the bulk alloy, NiPtAl. The alloy-coating study was designed to test the hypothesis that an extra layer of ...

The residual stress distributions in two 7449 aluminium alloy rectilinear blocks have been determined using neutron diffraction. Heat treatment included cold water immersion quenching and a period of precipitation hardening. ...

The use of traditional two-dimensional (2D) fibre preforms can be associated with poor out-of-plane and interlaminar mechanical performance, particularly in response to impact loads. Such preforms comprise multiple plies ...

Water purification technologies such as microfiltration/ultrafiltration and reverse osmosis utilize porous membranes to remove suspended particles and solutes. These membranes, however, cause many drawbacks such as a ...

PCR is a common and often indispensable technique used in medical and biological research labs for a variety of applications. Real-time quantitative PCR (RT-qPCR) has become a definitive technique for quantitating ...

In this paper, a nite-element modelling framework is presented with explicit representation of polycrystalline microstructure for a tempered martensite ferritic steel. A miniature notched specimen was manufactured from ...

Porous silicon finds numerous applications in the areas of bio-technology, drug delivery, energetic materials and catalysis. Recent studies by Vesta Sciences have led to the development of porous silicon nanosponge particles ...

Natural organic matter poses an increasing challenge to water managers because of its potential adverse impacts on water treatment and distribution, and subsequently human health. Projections were made of impacts of climate ...

Coronary artery disease is atherosclerosis of the coronary arteries that results in blockages or narrowing of the arterial wall, is caused by the accumulation of lipid-laden atherosclerotic plaque. Drug eluting stents ...

Physical risk factors and their combinations are linked to the causation of Musculo Skeletal Disorders (MSDs) which has implications for on-site operator productivity. Current risk assessment methods have no element to ...
