  1. 1. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)

    University essay from Uppsala universitet/Geofysik

    Author : Dimitra Daniil; [2021]
    Keywords : magnetic susceptibility; remanent magnetization; mDAC; AF demagnetization; NRM; IRM; ARM; magnetisk susceptibilitet; magnetisk remanens; mDAC; AF demagnetisering; NRM; IRM; ARM;

    Abstract : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.

  2. 2. Development of a CNC Milling System for Preparation of Micrometer-Sized Samples for X-ray Nanotomography

    University essay from KTH/Tillämpad fysik

    Author : Olivia Messler; [2021]
    Keywords : Nanotomography; Sample Preparation; CNC; Nanotomografi; Provpreparering; CNC;

    Abstract : X-­ray nanotomography is an imaging technique used to study three­-dimensional structures at submicrometer length scale. The samples to be studied should be only 10s of micrometers in diameter, and ideally cylindrical. READ MORE

  3. 3. Design of a wheel rig for studded tire wear and aerosol studies

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Weizhen Jiang; [2021]
    Keywords : studded tire; wear and aerosol; test rig; dubbdäck; slitage och aerosol; testrigg;

    Abstract : Studded tires are widely used in Nordic areas like Sweden for its good road-gripping performance on icy roads. However, the pavement wear and aerosol caused by studded tires become big concerns considering the usage of studded tires. Studies are carried to quantify the wear and aerosol generated during the process. READ MORE

  4. 4. Sustaining Orientation of Ubiquitin for Single Particle Imaging Using Electric Fields

    University essay from Uppsala universitet/Kemisk och biomolekylär fysik; Uppsala universitet/Energimaterialens fysik

    Author : Adi Bijedic; [2021]
    Keywords : ;

    Abstract : Single-particle imaging, or SPI, is a method used to obtain the three-dimensional structure of particles. Repeatedly aiming X-rays at samples of a particle produces diffraction patterns, which are combined to a best-fit three-dimensional model of the particle. SPI of proteins can be improved by orienting the protein before imaging. READ MORE

  5. 5. Preparative chromatographyfor modified oligonucleotides : Method development for modified oligonucleotides, fromanalytical to preparative chromatography

    University essay from Karlstads universitet

    Author : Rebecka Jasinski; [2021]
    Keywords : oligonucleotides; preparative chromatography; scaling-up; ion-pair chromatography; dibutylamine; oligonukleotider; preparativ kromatografi; uppskalning; jonparskromatografi; dibutylamin;

    Abstract : Synthetic oligonucleotides, which are short strings of DNA or RNA, are a grooving area of importance for the pharmaceutical industry and for companies that manufacture diagnostic components. The manufacturing process of synthetic oligonucleotides involves many complex processes that use separation and purification techniques like ion-exchange chromatography, ion-pair reversed phase chromatography and ultra-performance liquid chromatography.
