1. Synthesis of glass-ceramic Li2S-P2S5-based electrolyte for solid-state batteries
University essay from Uppsala universitet/Oorganisk kemiAbstract : In this project, solid sulphur based Li3PS4 electrolytes doped with Li4SiO4 were synthesised using two methods. In method A, a bought β-Li3PS4 electrolyte from Nei Corp was doped with 5 mole per cent Li4SiO4, resulting in a glass-ceramic electrolyte. READ MORE

2. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique
University essay from KTH/HållfasthetsläraAbstract : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.

3. Preparation and characterization of translucent glass ceramics
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : The purpose of this thesis is to prepare and characterize translucent glass ceramics. The procedure was as follows, first a general background of the field is presented where the problems with current dental glass ceramics are presented, together with their history. The need for a stronger material is then clarified with the addition of new metals. READ MORE

4. Effect of Veneering Dental Zirconia on Bond Strength. A pilot study
University essay from Umeå universitet/TandläkarutbildningAbstract : The objective of the study was to evaluate the effect of veneering zirconia surfaces with feldspar-based ceramics or glass ceramics on bond strength when using a resin composite cement. Forty-eight ytteria tetragonal zirconia polycrystal (Y-TZP) specimens were randomly divided into four groups. READ MORE

5. A manufacture system for a self suffient lunar colony
University essay from Institutionen för teknik, matematik och datavetenskapAbstract : Most of the needs for this colony of 500 persons can be supported by the moon itself. The Regolith (lunar dust) contains almost every element we need for our survival. The problem is to extract it by mining activities and the capability to store it in a proper way. Mining, manufacturing methods and power generation will be treated in this report. READ MORE
