  2. 6. Lake Dissolved Organic Matter Quantity and Quality : Variability across Temporal and Spatial Scales

    Author : Roger André Müller; Gesa Weyhenmeyer; Emily Stanley; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; organic carbon; CDOM; lakes; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Surface waters receive large amounts of dissolved organic matter (DOM) via runoff from land. The DOM is rich in organic carbon that serves as an energy source for the aquatic biota. During uptake of this energy, aquatic organisms mineralize organic carbon. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 8. Removal of natural organic matter by enhanced coagulation in Nicaragua

    Author : Indiana García; Luis Moreno; Olle Wahlberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; drinking water; surrogate parameters; enhanced coagulation; natural organic matter; Environmental chemistry; Miljökemi;

    Abstract : The existence of trihalomethanes (THMs) in a drinking water plant of Nicaragua has been investigated in order to see whether the concentration exceeded the maximum contaminant level recommended by the environmental protection agency of the United States (USEPA) and the Nicaragua guidelines. The influence of pH, temperature, chlorine dose and contact time on the formation of THMs were studied. READ MORE

  6. 9. Analysis of tracer molecules from organic aerosols - Application of liquid phase microextraction to aerosol analysis

    Author : Murtaza Hyder; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Liquid membrane extraction; Secondary organic aerosols; Enrichment; Tracers; Hollow fiber liquid phase microextraction; Biomass burning; Organic carbon;

    Abstract : Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. READ MORE

  7. 10. Mineralisation rates of natural organic matter in surface sediments affected by physical forces

    Author : Carina Ståhlberg; Bo Svensson; Lars Rahm; David Bastviken; Anders Tengberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sediment; Organic matter mineralisation; Organic matter degradation; Redox; Electron acceptor; Resuspension; Advective pore water flow; Other chemistry; Övrig kemi;

    Abstract : Nedbrytning av organiskt material är en nyckelfaktor som påverkar omvandlingar av de många grundämnen som utgör eller är associerade till just organiskt material. En stor del av nedbrytningen av akvatiskt organiskt material (OM) sker i gränsskiktet mellan sediment och vatten. READ MORE
