4. 2. Point defect interactions and structural stability of compounds

   Author : Vitaly Baykov; Börje Johansson; Peter Mohn; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; first principles; ab initio; density functional theory; point defects interactions; diluted magnetic semiconductors; structural stability; zirconium alloys; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : Theoretical studies of point defect interactions and structural stability of compounds have been performed using density functional theory. The defect-related properties, such as activation energy of diffusion, electronic and magnetic structure of selected materials have been studied. READ MORE

5. 3. Turbulent burning, flame acceleration, explosion triggering

   Author : V'yacheslav Akkerman; Vitaly Bychkov; Geoffrey Searby; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Turbulent combustion; flame acceleration; detonation explosion triggering; direct numerical simulations; Physics; Fysik;

   Abstract : The present thesis considers several important problems of combustion theory, which are closely related to each other: turbulent burning, flame interaction with walls in different geometries, flame acceleration and detonation triggering. The theory of turbulent burning is developed within the renormalization approach. READ MORE

6. 4. Effect of water on the glass transition and properties of solid-state pharmaceutical formulations

   Author : Ekaterina Bogdanova; Vitaly Kocherbitov; Thomas Rades; Malmö universitet; []
   Keywords : glass transition; glass transition temperature; relaxation; sucrose; trehalose; maltodextrin; lysozyme; unfolding; hydration; solid-stae; sorption calorimetry; Health and society; Hälsa och samhälle;

   Abstract : The aim of this thesis was to increase our knowledge of the glassy state and the glass transition phenomenon and to evaluate the effect of water on the glassy state. To accomplish this, investigations were focused on the amorphous sucrose-water (paper I, II, III), trehalose-water (paper I), maltodextrin-water (paper I), and lysozyme-sucrose-water (paper IV) systems.

7. 5. Hydrodynamics of Binary Bose-Einstein Condensates and Hydro-elasticity of the Inner Crust of Neutron Stars

   Author : Dmitry Kobyakov; Emil Lundh; Vitaly Bychkov; Mattias Marklund; Achim Schwenk; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Binary Bose-Einstein condensates in ultracold gases; hydrodynamics; quantum turbulence; neutron stars; the inner crust; nuclear astrophysics; fysik; Physics;

   Abstract : In the present thesis, “Hydrodynamics of Binary Bose-Einstein Condensates and Hydro-elasticity of the Inner Crust of Neutron Stars”, the hydrodynamic effects, instabilities and superfluid turbulence in binary immiscible ultracold gases, and hydro-elastic macroscopic coupled modes and microscopic structure of the inner layers of the crust of neutron stars, are studied. The ultracold gas dynamics can be realized in the laboratory. READ MORE
