  1. 16. Evaulation of liquid-exfoliatedgraphene as additive in Ag-basedsliding contacts

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Stina Juhlin; [2018]
    Keywords : liquid-exfoliated graphene; liquid exfoliated graphene; graphene; sliding contacts; additive in Ag-based sliding contacts; Raman; SEM; EDS; tribometer; liquid exfoliation; liquid phase exfoliation;

    Abstract : This master thesis work is performed at ABB Corporate Research Center inVästerås. The aim of this study is to investigate Ag:graphene composites as slidingelectrical contacts, suitable for use in e.g. tap-changers. READ MORE

  3. 17. Multidisciplinary perspectives on a natural attenuation zone in a PCE-contaminated aquifer

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robin Jansson; [2018]
    Keywords : DCIP; groundwater chemistry; Tetrachlorethene; PCE; natural attenuation; Earth and Environmental Sciences;

    Abstract : The old dry-cleaner in Hagfors, is one of the most seriously tetrachloroethene (PCE) contaminated sites in Sweden. Ever since the pollution was discovered in the groundwater in the 1990s, the site has undergone remedi-ation two times with limited success. READ MORE

  4. 18. TEM investigation on Challapampa aquifer, Oruro Bolivia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Måns Larsson; [2016]
    Keywords : kartering; survey geofysik; sedimentologi; geology; hydrogeology; geophysics; sedimentary; geologi; hydrogeologi; Earth and Environmental Sciences;

    Abstract : I denna studie utfördes en TEM (transient elektromagnetisk) undersökning på den Bolivianska altiplanon, norr om staden Oruro. I Oruro finns det ett underskott av dricksvatten och deras huvudsakliga vattenförsörjning kommer från aquiferen Challapampa. READ MORE

  5. 19. Who’s in charge? Electro-responsive QCM Studies of Ionic Liquid as an Additive in Lubricant Oils

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Bergendal Erik; [2016]
    Keywords : Quartz crystal microbalance; QCM; EQCM; Ionic Liquid; Lubricant additive;

    Abstract : Electrochemical quartz crystal microbalance has been employed to investigate electro-responsiveness of an ionic liquid as an additive in lubricant oils on a gold surface. Polarisation of the surface reveals changes in frequency where an increase in magnitude amplified the observed response, corresponding to a controllable alternation of the ionic liquid configuration on the surface as a function of applied potential.

  6. 20. Study of CVD deposited i-ZnO layers in CIGS thin film solar cells

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Fredrik Larsson; [2015]
    Keywords : CVD; CIGS; intrinsic; ZnO; thin film; solar cell;

    Abstract : CIGS thin film solar cells usually include a thin layer of intrinsic zinc oxide (i-ZnO) deposited on a CdS buffer layer by sputtering. However an interest has grown in using chemical vapor deposition (CVD) instead. READ MORE
