  1. 11. Reaction of Copper and Copper(I) Iodide with Iodine and Strong Field Ligands

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Aya Ali; [2022]
    Keywords : in films; AFM; copper iodide; solar cells; transparent conductive films; tunnfilm; AFM; koppar jodid; solceller; transparent ledande film;

    Abstract : Perovskit solceller (PSCs) är kända som 'ljusomvandling' enheter med ökad omvandlingseffektivitiet (PCE). PSCs är kända för detta flexibilitet och hög tolerans mot defekter och består av fem lager med olika material och egenskaper. READ MORE

  3. 12. Investigation of Methods to Improve PZT Sol-Gel Deposition Process for Energy Harvesting Applications

    University essay from KTH/Hälsoinformatik och logistik

    Author : Mikael Granberg; [2022]
    Keywords : PZT; sol-gel; self-polarization; seed layer; titanium oxidation; PZT; sol-gel; självpolarisering; seedlager; titanoxidering;

    Abstract : The purpose of this work was to investigate ways to modify Silex sol-gel deposition of PZT (PbZrxTi(1-x)O3, Lead Zirconate Titanate) in order to improve its properties for energy harvesting applications. A number of methods to improve the figure of merit for energy harvesting (FOM= e312/ε), cause self-polarization, increase lifetime, reduce cost, increase throughput or simplify processing were tested.

    Abstract : With a major share of the negative environmental impacts deriving from construction and its waste, ways to reduce the material and energy use in this sector have been the focus of studies for decades. Reuse of building elements and materials is gaining traction with researchers, architects, developers and real estate owners. READ MORE

  5. 14. Solar Energy Harvesting for Outdoor Applications

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Jonatan Andersson; Kristoffer Kjaerran; [2022]
    Keywords : Technology and Engineering;

    Abstract : The use of solar cells as a solution for different energy harvesting applications has seen a significant growth during the last few years. With recent advances in the power conversion efficiency and manufacturability of organic photovoltaic cells these systems can be made even cheaper and more available for consumers, opening up new ways for solar technology to be implemented into products.

  6. 15. The effect of three autogenous bone harvesting methods on bone volume

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Charlotte Nicklasson; Alise Austruma; [2022]
    Keywords : autogenous bone; bone block; harvesting; particulated bone; volume; autogent ben; benblock; skördning; partikulerat ben; volym;

    Abstract : ABSTRACT Aim: To evaluate the relation between harvested bone and acquired bone for threedifferent methods used to harvest autogenous bone. Material and method: Bone was harvested from 15 sheep mandibles using threetechniques: bone block, bone scraper, and bone rongeur. Volume change wasdigitally measured with TRIOS 3Shape and 3D Slicer.
