6. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types
Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysikSammanfattning : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. LÄS MER
7. Improving Product Level Sensing in Filling Tubes
Master-uppsats, Lunds universitet/InnovationSammanfattning : This thesis examines the possibility to improve the product level sensing in one of Tetra Pak’s filling machines, because the current solution does not detect this with the desirable precision, as well as measuring range. Today, a magnetic float is used together with 16 separate capacitive sensors. LÄS MER
8. Investigation of plasma cleaning on molybdenum crystals for diagnostic mirrors in fusion devices
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In the long-term energy scenario, nuclear fusion is a promising low-carbon and sustainable energy source. The unavoidable exposure of the wall materials to the plasma is a big challenge in realizing a fusion reactor. The plasma-facing components (PFCs) in the reactor wall will experience erosion deposition in the surface materials. LÄS MER
9. Active dielectrophoretic trapping for deterministic single-cell encapsulation in droplet microfluidics
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The research work focuses on optimizing various parameters for controlling cells using negative dielectrophoresis and entrapping them in droplet microfluidics. This is achieved by developing a conductivity medium, combining CytoRecovery, BSA, and EDTA, to maintain a steady count of single cells with good viability over an extended period. LÄS MER
10. Effects of Forest Ditch Cleaning on Surface Water Quality
Master-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : Ditch cleaning (DC) is recommended by authorities to Swedish landowners to maintain forest productivity after forest harvest by lowering groundwater tables of catchment soils. Knowledge regarding the impact of this practice on surface water quality is limited, and results from previous research vary. LÄS MER
