1. Studying Morphology Formation and Charge Separation in Organic Solar Cells
Sammanfattning : We are currently living in the era of automation and artificial intelligence, which requires more energy than ever before. Meanwhile, the reduction of carbon footprint is needed for keeping the environment sustainable. Exploring green energy is crucial. Solar power is one of the green energy sources. LÄS MER
2. Understanding the Impacts of Weather and Climate Change on Travel Behaviour
Sammanfattning : Human behaviour produces massive greenhouse gas emissions, which trigger climate change and more unpredictable weather conditions. The fluctuation of daily weather corresponds to variations of everyday travel behaviour. This influence, although is less noticeable, can have a strong impact on the transport system. LÄS MER
3. Modelling Evolution : From non-life, to life, to a variety of life
Sammanfattning : Life is able to replicate itself, e.g., a microorganism is able to divide into two identical ones, and a single plant is able to forest a whole island. LÄS MER
4. Development of new Fluorination Methods Directed to Fluorine-18 Labelling
Sammanfattning : This thesis deals with the development of new fluorination reactions and their application to fluorine-18 labelling. Fluorine-18 labelled compounds are employed as tracers in Positron Emission Tomography (PET), which is a powerful non-invasive imaging method in medical diagnostics. LÄS MER
5. Gas Exchange in the Normal Lung : Experimental studies on the effects of positive end-expiratory pressure and body position
Sammanfattning : BACKGROUND: The principal function of the lung is gas exchange requiring adequate ventilation and perfusion at the level of the alveoli. The efficiency of gas exchange is depending on the distributions of regional ventilation (V) and pulmonary blood flow (Q) and their correlation. LÄS MER
