    Författare :Marco Hernandez Velasco; Uwe Zimmermann; Anders Mattsson; Frank Fiedler; Johanna Riikonen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Picea abies; Pinus sylvestris; year-round cultivation; forest seedlings; LED lamps; light quality; light quantity; daily light integral; adaptive lighting control; greenhouse integrated photovoltaics; agrivoltaics; seedling growth performance; short-day treatments; cold hardiness; light shock stress; Engineering Science; Teknisk fysik;

    Sammanfattning : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. LÄS MER

  3. 2. Microbial Electrochemical System: extracellular electron transfer from photosynthesis and respiration to electrode

    Författare :Kamrul Hasan; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological photovoltaics; electron transfer; electrode; Rhodobacter capslatus; thylakoid membranes; cyanobacteria; algae; photosynthesis; light; photocurrent; electrochemistry;

    Sammanfattning : The electrochemical communication between microorganisms and electrodes has substantial implications both for basic understanding of biological electron transfer as well as in diverse applications, such as, microbial electrochemical system (MES), microbial biosensors and in production of valuable chemicals. In these systems the extracellular electron transfer (EET) from microbial metabolism to electrodes is restricted due to the insulated cellular exterior made of lipid structures. LÄS MER

  4. 3. Development of Molecular Biology and Bioinformatics Tools : From Hydrogen Evolution to Cell Division in Cyanobacteria

    Författare :Fernando Lopes Pinto; Peter Lindblad; Röbbe Wünschiers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; hydrogen; RNA; bioinformatics; RT-PCR; RACE; transcription; Molecular biology; Molekylärbiologi; Bioinformatics; Bioinformatik; Molecular Biology; Molekylärbiologi;

    Sammanfattning : The use of fossil fuels presents a particularly interesting challenge - our society strongly depends on coal and oil, but we are aware that their use is damaging the environment. Currently, this awareness is gaining momentum, and pressure to evolve towards an energetically cleaner planet is very strong. LÄS MER

  5. 4. Tuning of the Excited State Properties of Ruthenium(II)-Polypyridyl Complexes

    Författare :Maria Abrahamsson; Leif Hammarström; Hans-Christian Becker; Russell Schmehl; Uppsala universitet; []
    Nyckelord :Physical chemistry; Artificial photosynthesis; Ruthenium II ; Bistridentate complexes; Excited state lifetime; Linear donor-photosenstizer-acceptor arrays; Temperature dependence; Excited state decay; Fysikalisk kemi;

    Sammanfattning : Processes where a molecule absorbs visible light and then converts the solar energy into chemical energy are important in many biological systems, such as photosynthesis and also in many technical applications e.g. photovoltaics. LÄS MER

  7. 5. Excitonic and charge carrier transport in organic materials and device applications

    Författare :Qingzhen Bian; Olle Inganäs; Feng Gao; Ergang Wang; Guglielmo Lanzani; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With the potential for future commercial use, organic electronics have been intensively studied for the last few decades. To exploit the next generation of high-performance devices, detailed study of the underlying physics is essential. LÄS MER
