1. Time to ignition for wood covered with ZnO : A laboratory and theoretical study if ZnO can enhance time to ignition for wood exposed to radiation in the cone calorimeter
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : In recent years, interest in sustainability and being environmentally friendly has increased. Wood is a durable and renewable building material, which is becoming more common in the constructions industry. In 2002, the government in Sweden adopted a national strategy to promote an increased use of wood in buildings. LÄS MER
2. Development of chitosan nanocomposite coatings for visible-light photocatalytic antiviral applications
Master-uppsats, KTH/Tillämpad fysikSammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER
3. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemiSammanfattning : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

4. Prussian White In Sodium- Ion Batteries : An evaluation of organic and inorganic coatings on active material particles
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Emerging markets in electrochemical energy storage, such as stationary grid storage, coupled with future concerns over the availability of lithium, places sodium-ion battery (SIB) technologies at a unique position to enter the market as a commercially viable alternative. Current shortcomings in the performance of cathode materials in SIBs would necessarily need to be addressed if this technology is to compete with existing commercial lithium-ion battery counterparts.

5. Alternative Architectures of Quantum Dot Solar Cells
Master-uppsats, KTH/Tillämpad fysikalisk kemiSammanfattning : Kvantprickar är intressanta för tillverkning av solceller på grund av möjligheten att justera bandgapet beroende på kvantpricksstorleken. I detta examensarbete har alternativa arkitekturer av PbS kvantprickssolceller testats samt att påverkan av olika lager har utvärderats. LÄS MER
