  1. 21. X-ray Photoelectron Spectroscopy on Clusters: From Water Clusters to Metal & Metal-Oxide Nanoparticles

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Emmanouil Tzomos; [2021]
    Keywords : Nanoscience; Nanoparticles; Clusters; Synchrotron Radiation; Water Particles; Silver Particles; Silver Oxides; Ethylene Epoxidation; Radiotherapy; PES; XPS; Lund University; FlexPES; MAX IV; Physics and Astronomy;

    Abstract : In the present work, two experimental setups aimed at the production of (1) water clusters and (2) metal-oxide nanoparticles were assembled and commissioned. The experiments on the cluster/nanoparticle beams were set up and performed at the FlexPES beamline of the MAX-IV synchrotron facility. READ MORE

  2. 22. GEOCHEMICAL UNDERSTANDING OF VANADIUM IN MALMBERGET ORES (KIRUNA TYPE), NORTHERN SWEDEN

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Kabelo Kambai; [2021]
    Keywords : Vanadium; Malmberget; Kiruna Type;

    Abstract : The Norrbotten region is an important Swedish mining district with occurrence of several economic deposits and sub-economic deposits of apatite iron ores (Kiruna Type) and epigenetic Cu-Au ores. The apatite iron ores include the large Malmberget deposit mined by LKAB company as one of their world class underground mines. READ MORE

    Abstract : The challenges faced in today’s industry require materials capable of working in chemically aggressive environments at elevated temperature, which has fueled the development of oxidation resistant materials. All-Oxide Ceramic Matrix Composites (OCMC) are a promising material family due to their inherent chemical stability, moderate mechanical properties, and low weight. READ MORE

  4. 24. Tribological behaviour of metal sulfides UHMWPE composites in dry lubrication

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Bruno Pizone Vaz; [2021]
    Keywords : Polymer composites; polymer tribology; dry lubrication; UHMWPE; metal sulfides; tribology;

    Abstract : The increasing worldwide demand for more eco-friendly materials with improved tribo- logical properties has expanded the interest in research on polymer as an alternative for conventional metal/metal contacts under dry lubrication. Specifically, UHMWPE, a semi-crystalline polymer, has shown interesting tribological properties for low demanding applications, allied with excellent recyclability, manufacturability and low cost.
