1. Investigation of [N-X-N]+ and [N-C-N]+ complexes in solution Exploring Geometry, Stability and Symmetry
Sammanfattning : Halogen bonding is a weak interaction. In this thesis the three center four electron halogen bond, [N−X−N]+, has been studied. The lighter halogens form highly unstable halonium ions that are reactive towards nucleophiles and their complexes were therefore investigated at low temperatures. LÄS MER

Sammanfattning : The B8-type regions of the Mn-Sn and Cu-In systems have been investigated by means of electron and X-ray diffraction. The importance of the combination of these techniques in the study of B8-type phases is pointed out. In addition to the B8-type phases an alloy with a quasicrystal approximant structure has been studied. LÄS MER

Sammanfattning : The goals of this project were the two-dimensional crystallization of the membrane protein microsomal glutathione transferase 1 and the three-dimensional structure determination by electron crystallography. Microsomal glutathione transferase 1 is a homotrimeric membrane protein. LÄS MER
