  5. 4. Influence of Sample Preparation on Portable XRF-analyses of Aeolian Sediments: a Case Study

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Markus L. Fiola; [2017]
    Keywords : portable XRF; loess; sediment; bärbar XRF; lössjord; sediment;

    Abstract : The geochemical composition of aeolian sediments like windblown dust particles is of major importance for the exploration of dust origin and weathering conditions. This allows for the reconstruction of dust transport pathways and thus wind directions and palaeoclimate conditions. READ MORE

  6. 5. Electrochemical etching and anodizing as key stages of surface treatment of aluminium foil for electrolytic capacitor industry : Application of Electro Chemical Impedance Spectroscopy as non-destructive characterization of etched anode foil with an anodized dielectric oxide layer

    University essay from Högskolan i Jönköping/JTH, Produktutveckling; Högskolan i Jönköping/JTH, Material och tillverkning

    Author : Harish Appusamy Boopathy; Pavan Kumar Bonthala; [2017]
    Keywords : Surface treatment of aluminum foil for electrolytic capacitor; Anodic oxide forming process; Electro chemical etching; Electrochemical impedance spectroscopy EIS ; Capacitance measurement;

    Abstract : In the initial stage, the sample preparation was done by using the techniques of Anodic etching and anodic forming processes where a repeated trial and error method of sample preparation headed towards making out a suitable sample set for characterization. After this step, the set of 2 different industrial samples were introduced and anodic oxide forming process was carried out in different electrolytes. READ MORE
