1. Photochemical Surface Functionalization : Synthesis, Nanochemistry and Glycobiological Studies
Sammanfattning : This thesis mainly deals with the development of photochemical approaches to immobilize carbohydrates on surfaces for glycobiological studies. These approaches have been incorporated into a number of state-of-the-art nanobio-platforms, including carbohydrate microarrays, surface plasmon resonance (SPR), quartz crystal microbalance (QCM), atomic force microscopy (AFM), and glyconanomaterials.

2. Systematic Studies of Triplet Annihilating Species for Photochemical Upconversion
Sammanfattning : With climate change already setting new temperature records and causing more extreme weather events, transitioning to clean and renewable energy sources is more urgent than ever. Solar energy harvesting arguably holds the most promise with the abundance of terrestrial sunlight available. LÄS MER
3. Photoactive EDA complexes in visible light driven aerobic oxidations
Sammanfattning : Organic synthesis driven by photochemical activation has been proven very promising in a range of scenarios within academia and industry. The emergence of photoredox catalysis has fueled an ever-growing interest in the use of visible light as a convenient energy source for a variety of radical reactions otherwise difficult to achieve.

4. Damage mechanisms for near-infrared radiation induced cataract
Sammanfattning : Purpose: 1) To estimate the threshold dose and the time evolution for cataract induction by near infrared radiation (IRR) in seconds exposure time domain; 2) to determine the ocular temperature development during the threshold exposure; 3) to investigate if near IRR induces cumulative lens damage considering irradiance exposure time reciprocity; 4) to experimentally estimate the temperature in the lens indirectly from the measurement of temperature-induced light scattering increase.Methods: Before exposure, 6-weeks-old albino rats were anesthetized and the pupils of both eyes were dilated.

5. Photochemical alterations of dissolved organic matter : Impact on heterotrophic bacteria and carbon cycling in lakes
Sammanfattning : Globally, the amount of carbon in dissolved organic matter (DOM) is similar to the total amount in the atmosphere. DOM also plays a key role in structuring natural surface waters and affects the physical, chemical, and biological character of these systems. LÄS MER
