1. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. LÄS MER
2. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. LÄS MER
3. Chromatographic separation of rare earth elements using a novel extractant mixture
Master-uppsats, KTH/KemiteknikSammanfattning : Sällsynta jordartsmetaller är en kritisk råvara som står inför viktiga utmaningar gällande utbud och efterfrågan. För att överkomma dessa utmaningar behövs det effektiva separationsmetoder. Den här rapporten studerar separationen av sällsynta jordartsmetaller med extraktionskromatografi. LÄS MER
4. Peak Neodymium : Material Constraints for Future Wind Power Development
Master-uppsats, Institutionen för geovetenskaperSammanfattning : Developing renewable alternatives for energy production is one of the main methods for climate change mitigation and sustainable development. As the key component in permanent magnets, neodymium is considered as one of the most critical elements in the rare earth family in the development of modern society. LÄS MER
5. Optimization of Laser Induced Forward Transfer by Finite Element Modeling
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : This thesis explains a comprehensive study on the thermal modeling aspects of Laser Induced Forward Transfer (LIFT), a laser direct write technique. The LIFT process utilizes a focused laser beam to transfer a donor material coated on a laser wavelength transparent substrate to a receiver substrate kept in close proximity. LÄS MER
