1. Multiscale granular mechanics: A neutron diffraction based experimental approach
Sammanfattning : Granular media (i.e., assemblies of grains, containing voids), such as sand, are highly complex materials, possessing inherently heterogeneous structure and properties that are manifested by the mobility and interaction of their constituent particles. Despite having been widely studied for centuries (i. LÄS MER
2. Neutron scattering studies of hard metals
Sammanfattning : Since their discovery about 100 years ago, tools made of hard metals have been the enablers of development in various areas: from drilling subway lines for more sustainable cities to the machining of complex next-generation airplane engine parts for reduced CO2 emissions. An increase in properties of hard metals thus leads to efficient operations with shorter lead-time, less environmental footprint, and reduced cost. LÄS MER
3. Probing the Drip-Lines through Momentum Distributions
Sammanfattning : About a decade ago it was found that nuclei in the vicinity of the neutron drip-line under certain circumstances develop very extended valence neutron distributions, a phenomenon today known as halo states. The recent development of radioactive nuclear beams has provided us with a perfect tool for investigating these particular nuclei. LÄS MER
4. Raman Scattering and Neutron Diffraction Studies of Manganites and Cuprates
Sammanfattning : This thesis is devoted to experimental studies of two classes of strongly correlated transition metal oxides, namely cuprates and manganite perovskites. Manganites generally display complex phase diagrams, including the so-called colossal magnetoresistance effect. LÄS MER
5. Ionic Conduction and Bond Valence in Glasses
Sammanfattning : Ion conducting glasses are highly interesting for several different applications, among them, chemical sensors, smart windows with variable optical properties and as electrolytes in batteries. The last example can take full advantage of the ease with which a thin film (... LÄS MER
