  2. 1. The Influence of Energy Levels on Voltage Losses and Charge Generation in Organic Solar Cells

    Author : Jianwei Yu; Feng Gao; Olle Inganäs; Niclas Solin; Christoph J. Brabec; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Organic solar cells (OSCs) are a next-generation photovoltaic technology that convert solar energy to electrical energy. They have attracted great attention due to their advantages of low cost, ease of synthesis, light weight, mechanical flexibility, and roll-to-roll processability. READ MORE

  4. 2. Isomeric yield ratios in nuclear fission

    Author : Zhihao Gao; Andreas Solders; Ali Al-Adili; Mattias Lantz; Stephan Pomp; Olivier Serot; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear fission; isomeric yield ratio; angular momentum; independent fission yield; ion guide; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : Isomeric yield ratios (IYR), referring to the relative yield of the high spin states of a nucleus to the total yield of all observed states, is an observable of nuclear fission that has the potential to improve our understanding of the fission dynamics. Apart from that, systematic observations of IYRs can also contribute to other areas, such as the validation of fission models, modelling of the r-process in stellar nucleosynthesis, studies of the antineutrino mixing angle, the safety of present-day nuclear reactors, and the design of advanced reactor systems.

  5. 3. Machine Behavior Development and Analysis using Reinforcement Learning

    Author : Yuan Gao; Ginevra Castellano; Elin Anna Topp; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement learning; robotics; human robot interaction; Computer Science; Datavetenskap;

    Abstract : We are approaching a future where robots and humans will co-exist and co-adapt. To understand how can a robot co-adapt with humans, we need to understand and develop efficient algorithms suitable for our interactive purposes. Not only it can help us to advance the field of robotics but also it can help us to understand ourselves. READ MORE

  6. 4. Kinetic Monte Carlo Modelling of Organic Photovoltaic Devices

    Author : Tanvi Upreti; Martijn Kemerink; Feng Gao; Tayebeh Ameri; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Organic photovoltaics (OPVs) is a rapidly growing low-cost PV technology sector that relies on multiple benefits of organic semiconductors viz. being environmental-friendly with a simplified processing/fabrication and tunable properties. READ MORE

  7. 5. Production of polyhydroxyalkanoates in biological treatment of industrial wastewaters

    Author : Simon Bengtsson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyhydroxyalkanoates; mixed cultures; glycogen accumulating organisms GAO ; feast and famine; acidogenic fermentation; activated sludge;

    Abstract : In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. READ MORE
