1. Investigations on the Formation of Defect Bands in Semi-Solid High Pressure Die Cast Aluminium-Silicon Alloys
Sammanfattning : High-pressure die casting of semi-solid aluminium-silicon alloys is used in the automotive industry to manufacture components, like housings, brackets, and bars. It is commonly known that during high-pressure die casting, defect bands may be created that follow the contour of the component surface. These bands consist mainly of a eutectic phase. LÄS MER
2. Characteristics of cast magnesium alloys : microstructures, defects and mechanical properties
Sammanfattning : Magnesium is the lightest of all structural metals. As such, and combined with good mechanical and physical properties, it forms the basis for commercial alloys that have found successful use in a wide variety of applications. LÄS MER
3. High Bandgap FAPbBr3 Perovskite Solar Cells : Preparation, Characterization, and Application
Sammanfattning : High bandgap lead-halide perovskite solar cells (PSCs) have gained interest as top cells for tandem solar cells and photoelectrochemical applications due to their suitable energy bands. However, the PSCs have limited stability and performance, and their fabrication in a glovebox and utilization of expensive metal contacts increase the cost and limit their application. LÄS MER
4. On the Characterization and Generation of Flow Marks on Polymeric Surfaces
Sammanfattning : Polymer-based materials are widely used in the automotive industry for producing vehicle parts, for instance car bumpers, dash boards etc. A common manufacturing process for such components is injection moulding. LÄS MER
5. Everything is imperfect: Studies on point defects in insulators
Sammanfattning : Point defects can be detrimental or absolutely necessary for the performance of a material. Due to the implications defects have on a material, defects have been widely studied over the last century. LÄS MER
