  1. 1. Towards time-resolved cryo-EM of SARS-CoV-2 replication-transcription complex and Staphylococcus aureus DNA gyrase

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Anna Králová; [2023]
    Keywords : time-resolved cryo-EM; DNA gyrase; SARS-CoV-2; replication-transcription complex; protein purification;

    Abstract : Time-resolved cryo-EM has already provided ground-breaking discoveries in various fields, including structural biology, biochemistry, and drug development. Compared to traditional structural biology methods where mostly stabilized conformations are reconstructed, the main advantage of time-resolved cryo-EM is its ability to capture dynamic processes in biological samples at near-atomic resolution, which allows for studying biological structures as they change and interact in real-time.

  3. 2. Analysis of non-volatile chemicals from graminoid plants

    University essay from KTH/Kemi

    Author : Jakob Flygar; [2022]
    Keywords : Liquid Chromatography; Cyperus Rotundus; Panicum Repens; Malaria; Mass spectrometry; Vätskekromatografi; Cyperus Rotundus; Panicum Repens; Malaria; Masspektrometri;

    Abstract : Syftet med denna studie var att utveckla en separations- och analysmetod för identifiering av icke-volatila substanser från strån och rötter av de gräsliknande växterna Cyperus rotundus och Panicum repens. För analysen användes högpresterande vätskekromatografi (HPLC) och ultrahögpresterande vätskekromatografi (UHPLC) med en opolär stationär fas (RP-HPLC) med ultraviolett ljus (UV) och elektrosprej masspektrometri detektion (ESI-MS).

  4. 3. Characterization of micromotion induced by RF phase shift with photon correlation detection in a Paul trap

    University essay from KTH/Fysik

    Author : Ebba Edqvist; [2022]
    Keywords : Ion trap; Paul trap; Micromotion; Photon correlation detection; Jonfälla; Paul-fälla; Mikrorörelse; Fotonkorrelationsdetektion;

    Abstract : Trapped ions in a Paul trap can experience micromotion on top of the wanted secular motion.Micromotion can for example cause Doppler shifts in spectroscopy measurements, making it important to know the amplitude of the motion. READ MORE

  5. 4. Laser cooling, state initialization and laser manipulation of a trapped ion

    University essay from Stockholms universitet/Fysikum

    Author : Julius Andersson; [2021]
    Keywords : Ion trap; Quantum computer;

    Abstract : One way of realizing a quantum computer is to use an ion trap. The research group Trapped Ion Quantum Technologies at Stockholm university were operating an ion trap with strontium ions. To increase the coherence time they installed a magnetic field shielding. Therefore the experimental setup had to be partially rebuilt. READ MORE

  6. 5. Experimental Verification of BP-HiPIMS Thrusters

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Mainwaring; [2020]
    Keywords : Electric propulsion; BP-HiPIMS; Space propulsion; Elektriskframdrivning; BP-HiPIMS; Rymdframdrivningssystem;

    Abstract : The ion acceleration process in Bipolar High Power Impulse Magnetron Sputteringis investigated for use in a novel space propulsion system - the BP-HiPIMS thruster.The interest for BP-HiPIMS has recently been growing within the area of thin filmdeposition due to the theorised acceleration of target ions caused by the reversedpulse following the regular HiPIMS pulse.
