1. Nanofiltration at elevated temperatures: Influence of the combined effects of temperature, salts, pH and cleaning
Abstract : The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. READ MORE

2. Thermal Capacity of Railway Wheels - Temperatures, residual stresses and fatigue damage with special focus on metro applications
Abstract : Tread (block) braking is still one of the most common braking systems on railway vehicles.The action is carried out by pressing brake blocks against the tread of a wheel, which is also inrolling contact with the rail. READ MORE

3. Friction and Wear Phenomena in Steels at Elevated Temperatures
Abstract : Different grades of steels are often exposed to high temperatures whether during their shaping/forming or during their use in several applications. This exposure to high temperature has a great bearing on the resulting friction and wear phenomena in steels due to changes in their surface and near-surface properties. READ MORE

4. Quantitative Spectroscopy of Gas Phase Reactions at Elevated Temperatures
Abstract : Gas phase reactions at elevated temperatures are versatile tools for material manufacturing and energy conversion. They are of great commercial interest, but they often entail hazardous impacts on the environment. There is consequently a pronounced need for the further develpment of processes utilising these types of reactions. READ MORE

5. Degradation Mechanisms of Heat Resistant Steel at Elevated Temperatures : In an Iron Ore Pelletizing Industry
Abstract : This thesis focuses on the different degradation mechanisms of the stainless steel in a travelling grate in a Grate-Kiln iron ore pellet indurator. The travelling grate is a conveyor belt that transports green-body pellets to a rotary kiln while the pellets are being dried and pre-heated to a temperature of 900-1100 °C by recycled hot air.
