2. 1. Cooperative Lithium-Ion Insertion Mechanisms in Cathode Materials for Battery Applications

   Author : Helen Björk; Tsutomo Ohzuku; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Li-ion battery; cathode materials; single-crystal; X-ray diffraction; delithiation; superlattice; phase transformation; charge-ordering; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : Understanding lithium-ion insertion/extraction mechanisms in battery electrode materials is of crucial importance in developing new materials with better cycling performance. In this thesis, these mechanisms are probed for two different potential cathode materials by a combination of electrochemical and single-crystal X-ray diffraction studies. READ MORE

4. 2. 1D to 3D Magnetism in Quantum Materials: A study by Muons, Neutrons & X-rays

   Author : Ola Kenji Forslund; Martin Månsson; Robert Kiefl; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; muon; magnetism; scattering; quantum materials; Material and Nano Physics; Material- och nanofysik;

   Abstract : A collection of works stretching from low- to three-dimensional magnetism are presented, studied mostly through muon spin rotation, relaxation and resonance (µ +SR). The theoretical background of this technique is outlined in Chapter 2, which introduces the subject from the muon particle as an astro[1]nomical particle to how they are produced here on Earth.
