  1. 1. Thin Indium Tin Oxide Layer Development for Crystalline Silicon/Perovskite Two Terminal Tandem Solar Cell

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Aravind Srinivasachari; [2023]
    Nyckelord :Indium Tin Oxide; Thin-film characterisation; Magnetron Sputtering; Screen printing; Tandem Solar Cells; Indium-tennoxid; karaktärisering av tunnfilm; magnetronförstoftning; screentryck; tandemsolceller;

    Sammanfattning : ITO is widely regarded as the optimal TCO for serving as front window layer in PSK/c-Si tandem solar cells. It is known to effectively mitigate several stability issues present in perovskite solar cells while demonstrating excellent lateral conductivities and optical transparency across the entire solar spectrum.

  3. 2. Experimental Study of Heat Transfer Coefficient and Film Cooling Effectiveness

    Master-uppsats, KTH/Energiteknik

    Författare :Ke Li; [2019]
    Nyckelord :;

    Sammanfattning : This thesis investigates the possibility to evaluate the film cooling thermal performance on flat plate using Thermochromic Liquid Crystal. After an introduction of the basic concept and background of gas turbine blades film cooling and Thermochromic Liquid Crystal, a thorough explanation of four methods is presented. LÄS MER

  4. 3. Spectroscopic evaluation of stability and homogeneity of formulated lubricant

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Nyckelord :Lubricants; Base oil; ICP-AES; FTIR; Method validation; Smörjmedel; Basoljor; ICP-AES; FTIR; Metodvalidering;

    Sammanfattning : Lubricant is a common name for a large group of products that are essential for almost every engine or other machinery equipment that include mechanical part movements. Their main application is reduction of the friction between two rubbing surfaces by interposing a lubricating film between them. LÄS MER

  5. 4. Sex gymnasielärares syn på film i undervisningen: visuellt komplement eller slapp utfyllnad?

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för lärande, humaniora och samhälle

    Författare :Daniel Ohlander; Petter Åberg; [2019]
    Nyckelord :Films; School; Didactics; Civics; History; Teachers; Education; Optimal usage of film; Film; skola; samhällskunskap; historia; didaktik; inlärning; undervisning; optimal användning av film;

    Sammanfattning : This study focuses on teachers in civics and history in Swedish upper secondary schools. The study aims partly to examine how the teachers use film as a teaching method and how they motivate film as an educational tool in their classes. The study also assesses the thoughts of teachers regarding the optimal usage of film as an educational method. LÄS MER

  7. 5. Produktion av bakteriell cellulose genom användning av det symbiotiska förhållandet mellan bakterier och jäst som används vid Kombuchatillverkning

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Matilda Johansson; [2019]
    Nyckelord :resource recovery; biofilm; biopolymer; bioplastic; bacterial cellulose; circular economy; Kombucha; apple pomace; fruit juice; fruit waste;

    Sammanfattning : Different factors such as growing environmental awareness due to the increasing negative impact of persistent plastic wastes, the uncontrollable price variations of the raw material and the rapid depletion of  reserves have increased the interest in research regarding polymers derived from renewable sources to replace petroleum-based materials. One of the earth’s most abundant macromolecules is cellulose. LÄS MER
