1. Spänning- och flödessimulering av en högtrycksångventil
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Ventiler utgör en avgörande roll i det industriella samhället och används flitigt inom områden som säkerhet, filtrering och reglering av flöden. Säkerställandet av hållbarhet och drift av ventilen är därför ytters viktigt. Ventilen som undersöks har fyra packningsringar gjord av grafit. LÄS MER
2. Potential of tall oil pitch as phase change material in lignin-shelled hybrid nanocapsules for thermal energy storage.
Master-uppsats, Mittuniversitetet/Institutionen för kemiteknikSammanfattning : A prospect in utilizing thermal energy in development of energy systems is by the useof phase change materials (PCMs). PCMs are materials that can store and releaseenergy during phase changes, e.g. from solid to liquid. LÄS MER
3. Colliding Galaxies in a (Nut)Shell
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionenSammanfattning : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

4. Remediation of an arsenic-contaminated anoxic aquifer in hjältevad with zerovalent iron : assessment and modelling of sorption strength and solubility of arsenic
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : In-situ injection of zerovalent Iron (ZVI) particles to remediate contaminated groundwater is a widely applied approach. However, studies assessing the remediation and immobilisation mechanisms of Arsenic (As) under anoxic field conditions with zerovalent iron particles are lacking, especially for nanosized sulphidated ZVI (S-nZVI) and oxidic shell free ZVI (OSF-nZVI).

5. Nanocellulose surface functionalization for in-situ growth of zeolitic imidazolate framework 67 and 8
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella materialSammanfattning : This master’s thesis was conducted at the Department of Nanotechnology and Functional Materials at Ångström Laboratory as part of an on-going project to develop hybrid nanocomposites from Cladophora cellulose and a sub-type of metal-organic frameworks; zeolitic imidazolate frameworks (ZIFs). By utilizing a state-of-the-art interfacial synthesis approach, in-situ growth of ZIF particles on the cellulose could be achieved. LÄS MER
