  1. 21. Purification of Engineered Graphite for Advanced Application

    University essay from KTH/Materialvetenskap

    Author : Lingfeng Zhao; [2022]
    Keywords : Graphite; Purification; Acid washing; Biomass; Biochar;

    Abstract : Graphite has important applications in several key industries, which has been listed as a “criticalraw material” considered to be supply-risk by European since 2020. Purification of engineered graphite is one of the essential processes for the manufacturing of high-quality graphite. READ MORE

  3. 22. Greening peptide chemistry by using NBP as solvent for SPPS

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Andrea Ölander; [2022]
    Keywords : SPPS; Green chemistry; Peptide Synthesis; Organic chemistry; Organisk kemi; Chemistry;

    Abstract : The preferred method for synthesising therapeutic peptides today is by Solid-Phase Peptide Synthesis (SPPS). SPPS is a wasteful process, where the main component of the waste is hazardous solvents, i.e., N,N-dimethylformamide (DMF), N-methylpyrrolidone (NMP) or dichloromethane (DCM). READ MORE

  4. 23. Review of magnetic bead surface markers for stem cell separation : Literature study for MAGic Bioprocessing

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Gustav Holmberg; Adrian Svensson; Erik Bergström; Leo Westerberg; Watthachak Wijitchakhorn; [2022]
    Keywords : Magnetic bead; stem cell; surface antigen; immunotherapy; regenerative medicine; market analysis; separation technique;

    Abstract : Stem cell therapy and transplantation is a quickly evolving field with many clinical applications. However, several problems need to be overcome before they can be applied on an allogenic scale, and among them is ensuring of the purity of the applied differentiated stem cell culture. READ MORE

  5. 24. 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

  6. 25. Engineered imaging scaffolds for cryo-EM of small proteins of interest

    University essay from KTH/Proteinvetenskap

    Author : Oscar Friberg; [2022]
    Keywords : Protein structure determination; single-particle cryo-EM; imaging scaffold; size limitation problem; affibody; YgjG.;

    Abstract : Strukturbestämning av proteiner är viktigt för att kunna förstå deras funktion och en snabbt utvecklande metod inom fältet är kryoelektronmikroskopi. Storleksbegränsningar förhindrar en bredare applikation av metoden eftersom små proteiner har för låg signal i förhållande till bakgrund för att kunna visualiseras som enstaka partiklar i elektronmiksoskopibilder.
