The role of alloying elements on the microstructure and thermal stability of Refractory Metal High Entropy Superalloys (2021-03-19)Environmental targets require lower emissions, which necessitate increased operating efficiency for future generations of aeroengines. Consequently, higher operational temperatures will be needed, beyond the capabilities ...
Increased critical current density in rapidly grown RE-based cuprate superconducting coated conductors Coated conductor wire using superconducting Rare-earth-Ba2Cu3O7-x is a technology capable of producing many exciting new and improved devices, with applications from MRI magnets to fusion power plants. However, to be ...
(2021-02-08)This thesis covers research on the efficiency of green light emitting diodes (LEDs). The work presented focusses on the characterisation of conventional wurtzite (wz)-GaN based LEDs and novel zincblende (zb)-GaN based LEDs. ...
