  1. 16. Formation of cobalt oxide clusters on oxygen modified graphene

    University essay from Lunds universitet/MAX IV-laboratoriet; Lunds universitet/Fysiska institutionen

    Author : Robin Schneider; [2015]
    Keywords : Graphene; Cobalt oxide; clusters; STM; XPS; LEED; moire pattern; oxygen functionalized graphene; rocksalt; spinel; Iridium; Ir 111 ; monolayer graphene; oxygen radicals; carbon; Physics and Astronomy;

    Abstract : Aim of this thesis is to study and characterize the formation of cobalt oxide clusters on graphene. The performed experiments consist of three different steps. First, a monolayer graphene film is grown with temperature programmed growth and chemical vapor deposition on an Iridium (111) single crystal surface. READ MORE

  3. 17. Polymer structures for photovoltaics using colloidal self-assembly, thermal nanoimprinting and electrohydrodynamic annealing

    University essay from Institutionen för fysik

    Author : Ivan Huuva; [2012]
    Keywords : electric field; nanoimprinting; nanoimprint lithography; nil; electrohydrodynamic; ehd; polymer; organic electronics; photovoltaics; solar cells; patterning; self-assembly; colloidal crystal; imprint annealing; embedded annealing; patterning;

    Abstract : The efficiency of an organic photovoltaic cell depends mainly on its morphology where an exciton has to migrate to a p-n junction to create a photocurrent. Therefore the distance from the bulk of the cell to a junction interface should not exceed the diffusion length of the exciton. READ MORE

  4. 18. Relative influences of uncertainty in physical-chemical property data and variability in climate parameters in determining the fate of PCBs

    University essay from Kemiska institutionen

    Author : Li Zhe; [2011]
    Keywords : ;

    Abstract : Persistent organic pollutants (POPs) present a class of substances which are of high concern due to their toxicity and ecotoxicity, long-range atmospheric transport and resistance to degradation. A combination of analytical measurement and modeling researchis a powerful means for understanding chemical fate and behavior. READ MORE

  5. 19. Microspherules from the lowermost Ordovician in Scania, Sweden : affinity and taphonomy

    University essay from Lunds universitet/Geologiska institutionen

    Abstract : Microscopic spherules, 0.1-0.5 mm in diameter, from the lowermost Ordovician Rhabdinopora flabelliforme parabola graptolite Zone of the Alum Shale Formation in Södra Sandby, Scania, southern Sweden, have been investigated. READ MORE

  6. 20. Gas Adsorption Using Conjugated Polymers : Studied by Quartz Crystal Microbalance (QCM)

    University essay from Tema vatten i natur och samhälle

    Author : Yaser Rezania; [2010]
    Keywords : Congugated polymer; gas adsorption; carbon dioxide; methane; QCM;

    Abstract : Since late 70’s when conductive polymers were discovered, a new field of science has opened to the research world. Especially during last 30 years, many applications of using these polymers have been revealed in areas such as electrochemical transistors and OLEDs (Organic Light Emitting Diodes). READ MORE
