  1. 21. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae

    Författare :Helene Larsson Jönsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; UV-B; plant nutrients; photosynthesis; oxygen evolution; chlorophyll fluorescence; Cd uptake; cadmium; Arabidopsis thaliana; Brassica napus; Plant biochemistry; Växtbiokemi; Botany; Botanik;

    Sammanfattning : Plants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. LÄS MER

  3. 22. Terrestrial Ecosystem Interactions with Global Climate and Socio-Economics

    Författare :Anders Ahlström; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The global terrestrial carbon cycle plays a pivotal role in regulating the atmospheric composition of greenhouse gases. Currently it is responsible for removing 25-30% of our emissions every year, an important ecosystem service that may not persist in the long term. LÄS MER

  4. 23. Photophysics and Photochemistry of Iron Carbene Complexes

    Författare :Linnea Lindh; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tidsupplöst spektroskopi; täthetsfunktionalteori; järn-komplex; färgämne; grätzelsolcell; fotokatalys; elektronöverföringsreaktion; time-resolved spectroscopy; density functional theory; earth-abundant; iron-complex; photosensitiser; dye-sensitised solar cell; photocatalysis; electron transfer;

    Sammanfattning : Nature captures sunlight via light-absorbing molecules.Similarly, photosensitisers are used in applications of solar cells and artificial photosynthesis to absorb sunlight, and transfer the excited electron. LÄS MER

  5. 24. Microalgal solutions in Nordic conditions : industries transition toward resource recovery?

    Författare :Lina Mattsson; Catherine Legrand; Elin Lindehoff; Hanna Farnelid; Kristian Spilling; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; algal cultivation; polyculture; resource recovery; seasonal variation; industrial partnership; CO2 mitigation; nitrogen removal; community composition; Ecology; Ekologi; Environmental Biotechnology; Miljöbioteknik; Miljövetenskap; Environmental Science; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Sammanfattning : Microalgal solutions can through photosynthesis recover greenhouse gas (CO2) and nutrients from industrial waste, reducing climate footprint and eutrophication. An added value to the process is algal biomass containing lipids, proteins, and carbohydrates with commercial potential for biofuel, feed, and fertilizer. LÄS MER

  7. 25. The roles of Lhcb1 och Lhcb2 in regulation of photosynthetic light harvesting

    Författare :Malgorzata Pietrzykowska; Stefan Jansson; Jean-David Rochaix; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; Lhcb1; Lhcb2; LHCII; state transitions; phosphorylation; biology; biologi;

    Sammanfattning : Photosynthesis in higher plants relies upon collection of light by chlorophyll molecules associated with light harvesting chlorophyll a/b-binding (LHC) proteins. The two most abundant of these are Lhcb1 and Lhcb2, which make up light harvesting complex (LHC) II trimers. LÄS MER
