1. Syntetiskt pärlemor : Producerat via in situ-kristallisation
Master-uppsats,Sammanfattning : This thesis describes a sequence of experiments which have been performed with the intention to produce synthetic nacre. Synthetic nacre is a biomimetic material based on nacre, a material which can be found in mollusc shells. Nacre is a nanocomposite which has improved mechanical properties compared to the principal component aragonite (95% wt%). LÄS MER
2. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemiSammanfattning : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.

3. Numerical Simulations of Metal Recovery for Battery Recycling
Master-uppsats, KTH/ProcessteknologiSammanfattning : Den pågående elektrifieringen av transport och samhälle kräver utveckling av nya metoder för återvinning av batterier. Hydrometallurgi som fokuserar på selektiv kristallisation av metaller är ett intressant alternativ för dessa ändamål. Dessa system kan studeras genom modellering och simulering. LÄS MER
4. Assessing the controls of the fluoride concentrations in the groundwater of Gothenburg area
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : The human uptake of fluoride can promote healthy teeth in low concentration (1.5 mg/l). Drinking water is a major route to which we humans are expose to fluoride intake. LÄS MER
5. Study of yield variation in a pharmaceutical manufacturing process and optimization of purification subsection : By a design of experiments study of the production parameters and a laboratory study of the purification step
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : The product R1-MR2E is an ester formed from an esterification of a carboxylic acid and an alcohol at Cambrex Karlskoga AB. The production of the intermediate R1-MR2E is a large-scale production and there are two main objectives and two sub-objectives that this project aims to study of the manufacturing. LÄS MER
