1. 1. 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

   Författare :Rodrigo P. Carvalho; Moyses Araujo; Daniel Brandell; Susanne Mirbt; Wolfgang Wenzel; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Batteries; Artificial Intelligence; Organic electrodes; High-voltage cathode materials; Machine learning; Materials discovery; High throughput screening; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : Batteries have become an irreplaceable technology in human life as society becomes progressively more dependent on electricity. The demand for novel battery technologies has increased fast, especially with the popularisation of different portable devices. LÄS MER

4. 3. 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

5. 4. 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

7. 5. Organic Electrochemical Transistors : Materials and Challenges

   Författare :Silan Zhang; Simone Fabiano; Magnus Berggren; Jenny Nelson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The use of organic mixed ionic-electronic conductors (OMIECs) has demonstrated the potential to transform the field of bioelectronics, spanning from medical diagnostics to neuromorphic computing hardware. To keep up with the fast-paced demands, it is crucial to develop customizable device fabrication, design new materials, improve operation stability, and explore the ion-electron interactions within OMIECs.
