16. Thermodynamics of Hydrogen in Confined Lattice
Sammanfattning : Three of the most important questions concerning hydrogen storage in metals are how much hydrogen can be absorbed, how fast it can be absorbed (or released) and finally how strongly the hydrogen is bonded. In transition metals hydrogen occupies interstitial sites and the absorption as well as desorption of hydrogen can be fast. LÄS MER
17. Numerical study of flows related to aerated stirred tanks
Sammanfattning : The overall purpose with this work is to investigate the bubbly flow in a aerated stirred tank using numerical simulations. Aerated stirred tanks are commonly used in chemical processes for producing for example insulin and antibiotics. LÄS MER
18. Free Energy and Surface Forces in polymer systems: Monte Carlo Simulation Studies
Sammanfattning : The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. LÄS MER
19. Linear and Nonlinear Mechanics of Lattice Materials : Computational Modelling and Experiments
Sammanfattning : Lattice materials are artificial materials made of repeating unit-cells. The internal architecture of these materials can be engineered for a specific application such as energy absorption, heat transfer, or acoustic damping. LÄS MER
20. Higher Order Calculations for Low Energy Precision Physics
Sammanfattning : This thesis concerns higher order calculations needed for precision physics in the low energy region of particlephysics. Of the four papers it contains, the first two introduce calculations at order p8 in the power countingof chiral perturbation theory, which is an effective field theory of QCD at low energies. LÄS MER
