1. Computational Studies of the Temperature Dependence of Enzyme Catalysis
Sammanfattning : Enzymes are known to adapt to low temperatures by lowering the enthalpy of activation of the key reaction steps. A lesser known property of some psychrophilic (cold-active) enzymes is an anomalous temperature optimum. LÄS MER
2. Microbial temperature dependences in soil: The belowground feedback to climate change
Sammanfattning : Since the Industrial Revolution, human activities have elevated atmospheric CO2 concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. LÄS MER
3. Laminar burning velocity of hydrogen and flame structure of related fuels for detailed kinetic model validation
Sammanfattning : The laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. LÄS MER
4. Threshold and Temperature Characteristics of InGa(N)As-GaAs Multiple Quantum Well Lasers
Sammanfattning : Semiconductor lasers emitting in the 1.3 μm regime are of interest for applications in access-networks like fiber-to-the-home and radio-over-fiber systems. Suchfiber optical networks are expected to replace the copper-based access-networks currently in use due to a continuously increasing demand on user bandwidth. LÄS MER
5. Dilute Nitride Lasers and Spectrally Engineered Semiconductor Laser Resonators
Sammanfattning : The first part of this thesis deals with long wavelength (1.2-1.3 um) InGaAs(N)multiple quantum-well (QW) lasers grown on GaAs, with the aim of understandingand improving their threshold and temperature characteristics. The epitaxialmaterial is grown by molecular beam epitaxy (MBE). LÄS MER
