  1. 1. Virus Fate and Transport in Groundwater : Organic matter, uncertainty, and cold climate

    Författare :Jean-Marc Mayotte; Keven Bishop; Stephan Köhler; Fritjof Fagerlund; Sven Halldin; Constantinos V. Chrysikopoulos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; managed aquifer recharge; organic matter; virus; numerical modeling; uncertainty; Hydrology; Hydrologi; Mikrobiologi; Microbiology;

    Sammanfattning : Water managers must balance the need for clean and safe drinking water with ever-increasing amounts of waste-water. A technique for treating and storing surface water called “managed aquifer recharge” (MAR) is frequently used to help maintain this balance. LÄS MER

  3. 2. Organic Photodiodes : Optical, electric, and morphological aspects of polymer based devices

    Författare :Lucimara Stolz Roman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The use of semiconducting organic materials as the active layer in optoelectronic devices offers some advantages in processing and new possibilities of device fabrication such as large-area devices. The mechanism of charge generation upon light absorption in organic materials differs from that in inorganic semiconductors. LÄS MER

  4. 3. Switching Kinetics and Charge Transport in Organic Ferroelectrics

    Författare :Tim Cornelissen; Martijn Kemerink; Mats Fahlman; Kamal Asadi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Electronics; Ferroelectrics; Organic Ferroelectrics;

    Sammanfattning : The continued digitalization of our society means that more and more things are getting connected electronically. Since currently used inorganic electronics are not well suited for these new applications because of costs and environmental issues, organic electronics can play an important role here. LÄS MER

  5. 4. Exploring new protic ionic liquids: From synthesis to fundamental properties

    Författare :Eduardo Maurina Morais; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermal analysis; acidity; transport properties; DFT; Protic ionic liquids;

    Sammanfattning : The ionic liquid community frequently leverages the selling point that more than a million new ionic liquids could conceivably be created. Nonetheless, the number of commercially available compounds is orders of magnitude lower. LÄS MER

  7. 5. Compositional clues to sources and sinks of terrestrial organic matter transported to the Eurasian Arctic shelf

    Författare :Emma Karlsson; Örjan Gustafsson; Volker Brüchert; Thorsten Dittmar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic carbon; degradation; microcosm; incubation; terrestrial biomarkers; acyl lipids; lignin phenols; radiocarbon; Eurasian Arctic shelf; East Siberian Sea; Laptev Sea; Lena River; colloidal matter; particulate matter; sedimentary matter; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The amount of organic carbon (OC) present in Siberian Arctic permafrost soils is estimated at twice the amount of carbon currently in the atmosphere. The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion. LÄS MER
