1. 16. Selective Area Growth of AlGaN pyramid with GaN Multiple Quantum Wells

   Master-uppsats, Linköpings universitet/Halvledarmaterial

   Författare :Hsin-Yu Chen; [2018]
   Nyckelord :selective area growth; MOCVD; AlGaN pyramid; GaN multiple quantum wells; undesired deposition;

   Sammanfattning :   Since Shuji Nakamura, Hiroshi Amano, and Isamu Akasaki won the 2014 Nobel prize in Physics owing to theircontributions on the invention of efficient blue GaN light emitting diodes, GaN became an even more appealingmaterial system in the research field of optoelectronics. On the other hand, quantum structures or low-dimensionalstructures with properties derived from quantum physics demonstrate superior and unique electrical and opticalproperties, providing a significant potential on novel optoelectronic applications based on the employment of quantumconfinement.

3. 17. ”Riter vid vattnet” : En studie om religions materialitet vid bronsålderns rituella bassäng från Noceto, Italien

   Kandidat-uppsats, Uppsala universitet/Religionsbeteendevetenskap

   Författare :Serena Sabatini; [2018]
   Nyckelord :materiality; offer; performance; rituals; symbols; icons; indexes; agency;

   Sammanfattning : The essay is an interdisciplinary work linking History of Religion and Archaeology. The work is based on the study of the finds from a unique archaeological Italian Bronze Age site. The evidence in question has been recently excavated on the outskirts of the modern town of Noceto, Parma province, in northern Italy. LÄS MER

4. 18. Effect of oxygen concentration in build chamber during laser metal deposition of Ti-64 wire

   Master-uppsats, KTH/Materialvetenskap

   Författare :Eyvind Engblom; [2018]
   Nyckelord :additive manufacturing; laser metal deposition; alpha-case; titanium; wire;

   Sammanfattning : Additive manufacturing of titanium and other metals is a rapidly growing field that could potentially improve component manufacturing through optimization of geometries, less material waste and fewer process steps. Although powder-based additive manufacturing processes have so far been predominant, methods using a wire as feedstock has gained popularity due to faster deposition rates and lower porosity in deposited material.

5. 19. Different generation of controlled moraines in the glacier foreland of Midtdalsbreen, Norway

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Xavier Allègre; [2018]
   Nyckelord :Glacial sedimentology; glaciology; geomorphology; palaeoenvironmental reconstruction;

   Sammanfattning : A series of small mounds (< 3m) were sampled in the foreland of Midtdalsbreen outlet glacier, southern Norway. These landforms were interesting, especially at site number 1 because they were located very close to a higher Little Ice Age (LIA) moraine (> 5 m), thereby informing the dynamic of the glacier after the LIA at this location.

7. 20. Constructing supported lipid bilayers from native cell membranes

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Biofysikalisk kemi

   Författare :Tommy Dam; [2018]
   Nyckelord :T cells; Model membrane systems; Supported lipid bilayers; SLB; biophysical chemistry; biofysikalisk kemi; Chemistry;

   Sammanfattning : The aim of this MSc-project was to investigate whether it is possible to incorporate native cell membrane components from Jurkat T cells into supported lipid bilayers, SLBs, to produce a model membrane system better resembling the native cell membranes in T cells. The procedure of forming native-like SLBs (nSLB) was adapted from an existing protocol and is done through the deposition of hybrid vesicles onto a cleaned glass slide. LÄS MER
