1. Principal Component Analysis for STEM-EDS images: Optimal collection parameters
University essay from Lunds universitet/Centrum för analys och syntesAbstract : STEM-EDS is a common technique used for compositional mapping in materials. The vasts amounts of raw data produced by STEM EDS is suitable for advanced analysis using methods in unsupervised machine learning. One powerful method is Principal Component Analysis (PCA) which can automatically discover significant chemical correlations in a sample. READ MORE

2. Reduction of iron oxide by hydrogen studied using environmental transmission electron microscopy
University essay from Lunds universitet/Centrum för analys och syntesAbstract : This thesis aims to explore how the reduction of iron oxide by hydrogen should be explored in an environmental transmission electron microscope (ETEM). This is done by performing a series of reduction attempts in the ETEM at nCHREM, Lund University, and exploring how the ETEM conditions are different from those used commercially. READ MORE

3. An Investigation of the Adhesive Interaction between Polyethylene and Silicone with DMA and AFM
University essay from Lunds universitet/Centrum för analys och syntesAbstract : Stickiness between materials can be a challening task when dealing with the complex interactions and processes related to packaging engineering. Part of the problem is that many factors like temperature, pressure, surface treatment as well as surface roughness all could play a part in contributing to the stickiness between materials.

4. Iron-Based Dye-Sensitized Solar Cells - From Theory to Working Solar Cell
University essay from Lunds universitet/Centrum för analys och syntesAbstract : In the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions.

5. Dissolution and fibre spinning of cellulose from an ionic liquid
University essay from Lunds universitet/Centrum för analys och syntesAbstract : Regenerated cellulose fibres can become a sustainable alternative to cotton and polyester in textile applications. One method of producing such is dissolution of cellulose in an ionic liquid (IL) and regeneration through air-gap spinning. READ MORE
