1. Texter om Covid-19 på fyra regioners webbplatser : En analys av klarspråk och legitimering.
Kandidat-uppsats, Högskolan i Halmstad/Akademin för lärande, humaniora och samhälleSammanfattning : Denna uppsats undersöker klarspråk, legitimering och förekomsten av likheter och skillnader i fyra regioners informationstexter om Covid-19 i november 2020. Andreas Nords (2011) klarspråksmall tillämpas och Theo van Leeuwens (2007;2008) legitimeringsanalys. LÄS MER
2. Degradation of model biomedical Mg alloys in aqueous media
Master-uppsats, Lunds universitet/MaterialteknikSammanfattning : This project investigates the influence of alloying elements, heat treatment and corrosion medium on the corrosion rates of three magnesium alloys Mg-5Zn, Mg0.27Ca, and Mg-0.27Ca-5Zn for use in bio-medical applications. LÄS MER
3. Pitting Corrosion Evaluation of Post-Weld Cleaning Methods for Stainless Steel Welds
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Welding stainless steel creates an oxide film, heat tint, on the surface and around the joint. It disrupts passivation and influence the corrosion resistance for the material. The result is often a decrease in pitting corrosion resistance for the joint and surrounding area. The heat tint is therefore commonly removed by post weld cleaning. LÄS MER
4. Influence of Na doping on tunnelling rear contact passivation in Cu(In,Ga)Se2 solar cells
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronikSammanfattning : In this thesis Cu(In,Ga)Se2 (CIGS) solar cells with different sodiumdoping of the CIGS absorber and varying Al2O3 rear surface passivationlayer thickness have been manufactured and electrically characterised. Baseline samples and samples without passivation were used asreferences for the passivated samples. LÄS MER
5. Insight into the water oxidation mechanism on nickel hydroxide electrocatalysts : Density Functional Theory calculations and Electrochemical experiments
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Hydrogen production is an interesting way to store solar energy and to diversify the range of applications for indirect solar power. A promising production method is to use electric power from solar photovoltaic cells to split water in an electrolysis setup. LÄS MER
