Microstructure and transformation kinetics in bainitic steels

With the aim of reaching a better understanding of the microstructure evolution and the overall phase transformation kinetics in hyper-eutectoid steels a commercial SAE 52100 bearing steel and 7 model alloys with different concentrations of chromium, cobalt and aluminum have been studied in this work, both experimentally and theoretically. The...

Genetic Design of Ultra High Strength Stainless Steels: Modelling and Experiments

Sustainable Production of Cannabinoids with Supercritical Carbon Dioxide Technologies

This thesis concerns the production of natural compounds from plant material for pharmaceutical and food applications. It describes the production (extraction and isolation) of cannabinoids, the active components present in cannabis. Many cannabinoids have medicinal properties but not all cannabinoids are available in the (large) quantities...

Chemomechanics of Damage Accumulation and Damage-Recovery Healing in Bituminous Asphalt Binders

As a contribution to the development of mutli-scale multi-physics approaches to modelling pavement performance, the present thesis considers the topic of damage accumulation accompanied by damage recover self-healing of the bituminous asphalt phase of pavement systems. It is found insightful that by adopting Hveem’s [1943] concept of attributing...

Thermodynamics of Autogenous Self-healing in Cementitious Materials

Concrete is a brittle composite cementitious material that easily fractures under tensile loading. Microcracks can appear throughout the concrete prior to application of any load because of temperature-induced strain and autogenous and drying shrinkage. There is no doubt that these cracks provide preferential access for aggressive agents to...

Out-of-equilibrium self-assembly approaches for new soft materials

Living creatures exists for an important part out of soft material, such as skin, organs and cells, that are out-of-equilibrium formed by the self-assembly of molecular building blocks. Natural materials are continuously active with dynamic processes occurring, such as growth, shrinkage and transport mechanisms under the consumption of energy....

Thermodynamic characterization of salt components for Molten Salt Reactor fuel

The Molten Salt Reactor (MSR) is a promising future nuclear fission reactor technology with excellent performance in terms of safety and reliability, sustainability, proliferation resistance and economics. For the design and safety assessment of this concept, it is extremely important to have a thorough knowledge of the physico-chemical...

Supercritical Water Gasification of Wet Biomass: Modeling and Experiments

In the following decades, biomass will play an important role among the other renewable energy sources globally as it is already the fourth largest energy resource after coal, oil and natural gas. It is possible to obtain gaseous, liquid or solid biofuels from biomass via thermochemical or biochemical conversion routes. Among them, gasification...

Oxidation phenomena in advanced high strength steels: Modelling and experiment

Galvanized advanced high strength steels (AHSS) will be the most competitive structural material for automotive applications in the next decade. Oxidation of AHSS during the recrystalization annealing process in a continuous galvanizing line to a large extent influences the quality of zinc coating on the final galvanized steel product. For...

Thermodynamic Effects in Enzyme Regulation, Stereochemistry and Process Control

Thiamine diphosphate dependent enzymes are excellent catalysts for the asymmetric synthesis of the α-hydroxyketone (acyloin) structural motif, which is found in many pharmaceuticals and fine chemicals. In chapter 2, variants of transketolase from Saccharomyces cerevisiae were screened for the conversion of aliphatic aldehydes with...
