1. Preheating of ambient air by a system of earth tubes as a heat source for buildings
Sammanfattning : .... LÄS MER
2. Hydrodynamics, Erosion and Heat Transfer in Pressurized Fluidized Beds
Sammanfattning : Measurements of hydrodynamics, local tube erosion and local instantaneous bed-to-tube heat transfer were carried out in a cold, pressurized, fluidized bed with different horizontal tube banks. The influence of pressure, fluidization velocity, particle size and tube-bank geometry was studied. LÄS MER

5. Synthesis and applications of analogues of Tröger's base as molecular tubes, receptor and ligands
Sammanfattning : Tröger’s base was synthesized for the first time in 1887. The molecule is rigid, C2-symmetric and has a 90° angle, forming a chiral hydrophobic pocket. In this thesis, the synthesis of new analogues of Tröger’s base is described. 2- and 3-halo-substituted anilines have for the first time been condensed to Tröger’s base analogues. LÄS MER
