1. 1. Enhancing Mineral Carbonation of Olivine with CO2

   University essay from KTH/Kemiteknik

   Author : Ikaros Altantzis; [2023]
   Keywords : CO2 sequestration; Dissolution rate; Mineral carbonation; Olivine; Particle size; CO2-inlagring; Upplösningshastighet; Mineral kolsyrning; Olivin; Partikelstorlek;

   Abstract : Koldioxidutsläpp (CO2) från energiproduktionsindustrin och transportsektorn globalt påverkar miljön negativt. Länder har enats om att minska utsläppen för att nå målet om en genomsnittlig temperaturökning på 1,5 °C till 2030. READ MORE

3. 2. Rotational Properties of Lee-Huang-Yang Bosonic Condensates from One to Two Dimensions

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

   Author : Hjalmar Holmström; [2022]
   Keywords : BEC; Bose-Einstein condensate; quantum fluid; Quantum mechanics; LHY; LHY-fluid; Lee-Huang-Yang; Rotating BEC; BEC droplet; Physics and Astronomy;

   Abstract : This thesis covers the work of a numerical examination of the rotational properties of a two-component Bose-Einstein condensate (BEC) utilizing the beyond mean-field extended Gross-Pitaevskii equation for a specified set of parameters. These parameters are chosen to cancel the strength of the mean-field interaction, which makes the system predominantly governed by the next order beyond the mean-field Lee-Huang-Yang (LHY) term.

4. 3. Methods for measuring mercury in gas ebullition from fiber banks : A literature study

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Diana Jonsson; [2021]
   Keywords : Fiber bank; fiber rich-sediment; mercury; contaminants; gas ebullition; pulp-fiber; wood industry; paper industry; environmental toxicity; wood waste;

   Abstract : Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. READ MORE

5. 4. Practical investigation of mixing phenomena by physical modelling : Scaling criteria applied for bottom gas-stirred water modelling of metallurgical vessels

   University essay from KTH/Materialvetenskap

   Author : Simon Garpenquist; Carl Erik Sebastian Lindfors; [2021]
   Keywords : Ladle furnace; Water model; Mixing time; Modified Froude number; Scaling criteria; Scaling factors; Skänkmetallurgi; Vattenmodell; Blandningstid; Froude s modifierade tal; Skalnings kriterier; Skalnings faktorer;

   Abstract : Gas stirring is currently the most commonly used method of homogenizing liquid steel in commercial processes. However, due to the harsh environment during the process, physical models built out of e.g. plexiglass have been used to easier understand the complex phenomenon occurring in the process. READ MORE

6. 5. Real-time stability and dynamics of vortices in quasi-two-dimensional self-bound two-component Bose-Einstein condensate

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

   Author : Philipp Stürmer; [2019]
   Keywords : Bose-Einstein condensate; bosons; self-bound; cold atom gases; vortex; Physics and Astronomy;

   Abstract : This thesis presents a numerical study of the beyond mean field extended Gross-Pitaevskii equation for a two-component self-bound Bose-Einstein condensate, supplemented by analytical work. We extend the quasi-two-dimensional system's mean field particle-particle contact interaction by quantum fluctuations (LHY-correction). READ MORE
