  2. 1. Studying Morphology Formation and Charge Separation in Organic Solar Cells

    Author : Yanfeng Liu; Fengling Zhang; Olle Inganäs; Jonas Bergqvist; Christoph J. Brabec; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  4. 2. Understanding the Impacts of Weather and Climate Change on Travel Behaviour

    Author : Liu Chengxi; Yusak O. Susilo; Karlström Anders; Kelly J. Clifton; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impacts of weather; climate change; travel survey; spatial heterogeneity; activity-travel pattern; weather perception; passenger transport CO2 emission; Transportvetenskap; Transport Science;

    Abstract : 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. READ MORE

  5. 3. Modelling Evolution : From non-life, to life, to a variety of life

    Author : Yu Liu; David J. T. Sumpter; Peter Dittrich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical biology; Biocomplexity; Artificial chemistry; Ecosystem evolution; Origin of life; Self-replication; Prebiotic evolution; Collectively-catalytic; Golden ratio; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Abstract : 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. READ MORE

  6. 4. Development of new Fluorination Methods Directed to Fluorine-18 Labelling

    Author : Miguel Ángel Cortés González; Kálmán J. Szabó; Guosheng Liu; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorine; fluorine-18; late-stage; labelling; nucleophilic; electrophilic; fluorination; positron emision tomography; PET; hypervalent iodine; benziodoxole; metal-free; DBU; copper; palladium; rhodium; carbene; organisk kemi; Organic Chemistry;

    Abstract : 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. READ MORE

  7. 5. Gas Exchange in the Normal Lung : Experimental studies on the effects of positive end-expiratory pressure and body position

    Author : Mats J. Johansson; Sten Walther; Gunnar Nicolaysen; John-Peder Escobar Kvitting; Stefan Lundin; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : 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. READ MORE
