41. Local structure in disordered materials studied by neutron scattering and RMC modelling
Sammanfattning : Different disordered materials are becoming more and more important in various technological applications. There is a need to improve our detailed understanding of the local structure of such materials and how the atomic structure is related to macroscopic physical properties. LÄS MER
42. Structure-Magnetic Relationships in the Fe-Mn-P-Si System for Energy Applications
Sammanfattning : Demands for new, energy-efficient appliances have greatly increased in response to our growing need for a more environmentally friendly society. Magnetic refrigeration is a technique that utilizes the magnetocaloric effect, with possible energy savings of up to 30% compared to commercial gas compression refrigerators. LÄS MER
43. Production of Perdeuterated Proteins in Escherichia coli for Structural Studies by Neutron Crystallography
Sammanfattning : Neutron macromolecular crystallography (NMX) is a complementary technique to X-ray crystallography leveraging neutron scattering properties of the hydrogen isotope deuterium (2H). Production of deuterium labelled molecules together with large crystal requirements for neutron crystallography are few of several bottlenecks limiting implementation of this technique for a wider range of proteins.
