1. A Nonlinear Optimization Approach to H2-Optimal Modeling and Control
Sammanfattning : Mathematical models of physical systems are pervasive in engineering. These models can be used to analyze properties of the system, to simulate the system, or synthesize controllers. However, many of these models are too complex or too large for standard analysis and synthesis methods to be applicable. LÄS MER
2. Adsorption isotherms of H2 and mixtures of H2, CH4, CO and CO2 on copper plated stainless steel at 4.2 K and the large hadron collider vacuum system
Sammanfattning : .... LÄS MER
3. High Temperature Corrosion of Stainless Steels in Low Oxygen Activity Environments -The effect of H2 and H2O
Sammanfattning : Gasification of biomass and waste is promising for reducing the use of fossil fuels. While the operation conditions of superheaters and gas coolers in the gasifier are restricted by gas-side corrosion, scientific investigations are very scarce in this field. LÄS MER
4. Heterocystous cyanobacteria, Dps proteins and H2 production
Sammanfattning : To mitigate climate change, CO2-emitting technologies have to be exchanged by renewable alternatives such as H2. H2 can be produced by cyanobacteria, but major efforts to enhance H2 production yields by genetic modifications or optimised cultivation conditions resulted in energetic photo-to-H2 conversion efficiencies of 4.

5. Novel catalysts development for NOx reduction from H2 combustion engines
Sammanfattning : Hydrogen, as a clean energy carrier, burns without producing any carbon emissions. Hydrogen internal combustion engines (H2-ICE) are considered an alternative for the transition from conventional fossil-fuel vehicles. LÄS MER
