  1. 1. The effect of calcium silicate-based cements on viability and differentiation of human stem cells from the dental apical papilla. : Future aspects in endodontic regeneration.

    Master-uppsats, Umeå universitet/Wallenberg centrum för molekylär medicin vid Umeå universitet (WCMM); Umeå universitet/Tandläkarutbildning

    Författare :Lahood Abdalla; Bagir Soltani; [2023]
    Nyckelord :MTA; Biodentine; SCAP; Regenerativ endodonti; endodonti; traumatiserade tänder; tänder; unga tänder;

    Sammanfattning : Introduction: Pulp necrosis in immature permanent teeth stops root development and may lead to higher risk of cervical fractures and a challenging treatment. Regenerative endodontic treatment (RET) aims to continue tooth development and implies the use of calcium silicate-based cements, such as Mineral trioxide aggregate (MTA) and Biodentine to seal the root canal.

  3. 2. The Effect of Residual Bacterial Products Associated to Root Canal Infection on Stem Cells from the Apical Papilla: Understanding Basis on Regenerative Endodontic Treatment

    Master-uppsats, Umeå universitet/Tandläkarutbildning

    Författare :Alhussan Sora; Abla Afnan; [2022]
    Nyckelord :SCAP; RTCA; regenerative endodontic; Inactivated bacteria;

    Sammanfattning : Background: The regenerative function of stem cells from the apical papilla (SCAPs) is affected by the presence of bacteria from infected root canals. Living microorganisms influence SCAP function but the effect of inactive bacteria and its components on SCAPs needs further investigation. LÄS MER

  4. 3. Electrical analysis of interface recombination of thin-film CIGS solar cells

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Henrik Lotse; [2020]
    Nyckelord :interface recombination; SCAPS; activation energy; temperature dependent IV; dominant recombination path;

    Sammanfattning : In this master thesis, electrical characterization of thin film CuInxGa(1−x)Se2 solar cells produced by Midsummer AB were performed with the aim of determining the dominant recombination path of these cells. Current-Voltage (IV), Quantum Effinciency (QE), temperature dependent IV (IVT) and Drive-Level Capacitance Profiling (DLCP) was used with the objective to investigate the dominant recombination path as well as provide some insight of the solar cells in order to create a baseline model using the modelling software SCAPS (Solar cell CAPacitance Simulator).

  5. 4. Advanced rear contact design for CIGS solar cells

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jorge Alexandre De Abreu Mafalda; [2019]
    Nyckelord :CIGS; HfO2; surface passivation; alkali treatment; point contact openings; SCAPS;

    Sammanfattning : The current trend concerning the thinning of solar cell devices is mainly motivated by economic aspects, such as the cost of the used rare-earth elements, and by the requirements of emergent technologies. The introduction of ultra-thin absorber layers results in a reduction of used materials and thus contributes to a more cost-effective and time-efficient production process. LÄS MER

  7. 5. Effects of the interfaces in planar hybrid lead trihalide perovskite solar cells with n-type and p-type inorganic charge transport layers

    Master-uppsats, KTH/Energiteknik

    Författare :Olivier Jaques Henri Fournier; [2018]
    Nyckelord :;

    Sammanfattning : Perovskite-solceller är en framväxande och lovande tunnfilmsteknik, som uppnådde hög effektivitet på en ofantlig kort tid. Den nuvarande arkitekturen i cellen, som innefattar titanoxid och Spiro-OMeTAD (en organisk förening) som laddningstransportlager (CTL), saknar stabilitet och visar hysteretiskt beteende. LÄS MER
