11. 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 tillverkningAbstract : 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

12. Surface Treatment of Photocatalyst Metal Supports for VOCs Abatement Applications
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : In this work, the preparation of photocatalysts’ metal support for applications in purification of industrial gas emissions has been studied. The supports normally used in literature are ceramics, but they are not suitable for industrial applications. READ MORE

13. Chemical Vapor Deposition Growth and Density Functional Theory Calculations of Trilayer Graphene
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : Density functional theory was employed to investigate the energetics of ABA, ABC, and intermediary stacked phases for both pristine and s-triazine functionalized graphene trilayers. The energy of the ABC-stacked phase relative to the pristine ABA-stacked ground state showed a 94% increase when s-triazine was adsorbed to the graphene surface, confirming previous studies of the ability of s-triazine to facilitate the ABC to ABA phase-transition.

14. Rear side BSF/emitter patterning of SHJ-IBC solar cells using selective deposition and hydrogen plasma etching of a-Si:H
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : Silicon heterojunction interdigitated back-contact (SHJ-IBC) solar cells have attracted considerable attention because of their potential to achieve very highly efficiency. However, the back contacting scheme leads to additional fabrication complexity mainly resulting from the formation of interdigitated n- (back surface field (BSF)) and p-type (emitter) hydrogenated amorphous silicon (aSi:H) strips.

15. X-ray diffraction studies on complex metal oxides
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : The ambition of this project is to assist in the pursuance of understanding the metal to insulator transition found in magnetite at ~120 K. The transition is itself very complex and links together the charge order, orbital order and lattice distortion of magnetite with its magnetic properties. READ MORE
