1. 1. Lithium-ion Behaviour in Hard Carbon Anodes: Insights from 7Li NMR Spectroscopy

   University essay from KTH/Kemi

   Author : Adina Landström; [2023]
   Keywords : NMR spectroscopy; hard carbon; anode; lithium-ion battery; spin relaxation; NMR-spektroskopi; hårt kol; anod; litiumjonbatteri; spinnrelaxation;

   Abstract : Litiumjonbatterier (LIB) är viktiga komponenter i dagens teknologi och används för att driva en mängd olika elektroniska system, allt från datorer och mobiltelefoner till bilar och flygplan. Eftersom efterfrågan på effektiv energilagring fortsätter att växa finns ett fortsatt behov för forskning och utveckling inom området. READ MORE

3. 2. Hydrogen-Methane combustion modeling in the burner of the SGT-800 Siemens Energy gas turbine

   University essay from KTH/Teknisk mekanik

   Author : Nikolaos Bozikis; [2022]
   Keywords : Engineering mechanics; fluid dynamics; CFD; combustion modeling; industrial gas turbines;

   Abstract : Industrial gas turbines constitute an integral part of today’s electricalpower production infrastructure. Reacting gas flows in these machines arevery interesting and complex in nature since they exhibit highly turbulentbehaviour which is strongly coupled to the chemical reaction dynamics. READ MORE

4. 3. Measurement & Feedback Control of a Two Level System

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Sayan Ali Khan; [2022]
   Keywords : Quantum Measurement; Generalized Measurements; POVM Positive Operator Valued Measure ; Feedback Control; Two-Level System; Physics and Astronomy;

   Abstract : In this bachelor project, the main objective is to investigate how a two-level quantum system can be controlled using weak continuous measurements and feedback control. The Monte-Carlo method was used to simulate the system dynamics under measurement and feedback to investigate how the system state can be controlled. READ MORE

5. 4. Automatization of de-powdering process for binder jetting technology

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Mikael Borg; [2022]
   Keywords : additive manufacturing; binder jetting; computational fluid dynamics; computer aided design; de-powdering;

   Abstract : Additive manufacturing has gained considerable attention in recent years due to its capabilities of producing complex parts with tailormade mechanical properties. Because of its infancy state, additive manufacturing production chains are seldom optimized to the same extent as conventional manufacturing techniques. READ MORE

6. 5. Geometrical Improvement of Fuel Nozzle Locations in the SGT-750 Gas Turbine : An investigation into fuel-air mixing in main channels 1 & 2

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Aryan Delir; [2022]
   Keywords : gas turbine engines; turbofan; combustion; SGT-750; flashback; hydrogen; natural gas; premixing; fuel-air mixing; computational fluid dynamics; CFD; turbulence modelling; NOx emission; lean premixed mixture;

   Abstract : This study was conducted on SGT-750, which utilizes can type fourth generation DLE burner, developed at Siemens Energy AB, in Finspång, Sweden. The aim of this study is to obtain a flat fuel profile at the outlet of main channel 1 and main channel 2, demonstrating a proper mixing of fuel and air in the main channels leading to reducing local high-temperature points, and thus, reducing thermal NOx emissions.
