1. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques
Sammanfattning : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. LÄS MER
2. Exploration of Non-Aqueous Metal-O2 Batteries via In Operando X-ray Diffraction
Sammanfattning : Non-aqueous metal-air (Li-O2 and Na-O2) batteries have been emerging as one of the most promising high-energy storage systems to meet the requirements for demanding applications due to their high theoretical specific energy. In the present thesis work, advanced characterization techniques are demonstrated for the exploration of metal-O2 batteries. LÄS MER
3. Synchrotron X-ray based characterization of technologically relevant III-V surfaces and nanostructures
Sammanfattning : Innovative design and materials are needed to satisfy the demand for efficient and scalable devices for electronic and opto-electronic applications, such as transistors, LEDs, and solar cells. Nanostructured III-V semiconductors are an appealing solution, combining the excellent functional properties of III-V materials with the flexibility typical of nanostructures, such as the nanowires (NWs) studied here.
