1. Experiments and simulations of gas flow through a NiCd battery
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This report describes the thesis work carried out regarding experiments and simulations of the gas flow through a NiCd battery. The objective of the work was to investigate how different geometries of the flip top vent on the battery and the level of porosity of the flame arresting disc impacted the amount of potassium carbonate created at the outlet of the vent.

2. Design av ångexplosionsreaktor : Utformning av ångexplosionsreaktor för laborativt bruk
Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)Sammanfattning : Förbehandling av lignocellulosa genom ångexplosion är en förbehandling av biomassa som förändrar strukturen i fibrernas cellväggar. Vid förbehandlingen värms biomassa med mättad ånga under tryck till minst 140 ˚C, detta leder till att flyktiga ämnen avgår från biomassan. LÄS MER
3. Water purification of ibuprofen using whey protein aerogels with and without PNF-structure
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Clean water, free from pharmaceuticals, is important both for land and water living animals. Protein nanofibrils (PNFs) have already been shown to be a promising candidate for water purification of pharmaceuticals but there is a lack of research that compares PNF materials to non-PNF protein materials for water purification.

4. Ammonium and nitrate sorption by biochar
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

5. Geologisk karaktärisering av den kambriska Faluddensandstenen i Östersjön och dess lämplighet för koldioxidlagring
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The Geological Survey of Sweden (SGU) has spent several years investigating the Swedish bedrock to find suitable bedrock for geological storage of carbon dioxide. Deep saline aquifers are considered to have the greatest potential, and the Cambrian Faludden Sandstone subcropping in the Baltic Sea east of Gotland, shows great potential as a storage aquifer.
