1. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering
Sammanfattning : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. LÄS MER
2. Color Tuning for Perovskite Light-Emitting Diodes
Sammanfattning : Metal halide perovskites (MHPs) are recognized as promising semiconductor materials for a variety of optical and electrical device applications due to their cost-effective and outstanding optoelectronic properties. As one of the most significant applications, perovskite light-emitting diodes (PeLEDs) hold promise for future lighting and display technologies, attributed to their high photoluminescence quantum yield (PLQY), high color purity, and tunable emission color.

3. Silicon Nanowire Based Sensors for Bacterial Tests
Sammanfattning : Rapid and reliable antibiotic susceptibility testing (AST) is urgently required to diagnose bacterial infectious diseases and avoid antibiotic misuse, providing valuable information on the efficacy of antibiotic agents and their dosages for treatment. However, the currently employed phenotypic ASTs normally demand the growth of bacteria into colonies, which usually takes more than two days. LÄS MER
4. Fibre Bragg Grating Components for Filtering, Switching and Lasing
Sammanfattning : Fibre Bragg gratings (FBGs) are key components for a vast number of applications in optical communication systems, microwave photonics systems, and optical sensors, etc. The main topic of this thesis is fibre Bragg grating fabrication and applications in direct microwave optical filtering, high speed switching and switchable dual-wavelength fibre lasers.
