    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Sebastian Öhman; [2016]
    Keywords : Wear; Alumina; Al2O3; Coating; Coated; coatings; Tools; Cutting tool; Cemented Carbide; Inclusions; Steel; Steels; SS2541; Sandvik; Coromant; Nötning; Förslitning; Aluminiumoxid; Al2O3; Beläggning; Ytbeläggning; Tunnfilm; Tunnfilmsteknik; Verktyg; Skärverktyg; Hårdmetall; Inneslutning; Stål; SS2541; Sandvik; Coromant; Deformation;

    Abstract : In this master thesis, performed at Sandvik Coromant Västberga (Stockholm), a comprehensive study has been made to investigate the wear on textured alumina (Inveio™) coated cutting tools when turning low-alloy steels. Specifically, wear studies have been made on tools’ rake faces when turning two separate batches of SS2541, after an initial turning time of 4 min. READ MORE

  3. 12. CO induced faceting of Rh(553)

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

    Author : Ka Sin Lai; [2015]
    Keywords : Science General;

    Abstract : We have investigated the CO induced faceting of a Rh(553) surface using Scanning Tunneling Microscope (STM), Low Energy Electron Diffraction (LEED) and Auger Electron Spectroscopy (AES). The sample was exposed to a CO pressure of 1x10^-3 mbar, at different sample temperatures. READ MORE

  4. 13. The Influence of Oxygen on Nanowire Surface Structure and Electronic Properties

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

    Author : Viktor Abelin; [2015]
    Keywords : Scanning tunneling microscopy; STM; Auger electron spectroscopy; AES; nanowire; hydrogen cleaning; Physics and Astronomy;

    Abstract : This thesis investigates the possibilities for setups measuring how the surface structure of nanowires (NWs) influences their electric properties. For this the abilities to clean surfaces and detect nanowires (NWs) are examined, and an attempt to build a setup is made. READ MORE

  5. 14. Improving green LEDs: A meta study into the causes and remedies of the green gap

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Andreas Malmgren; [2015]
    Keywords : Light emitting diodes; quantum wells; recombination rate; Technology and Engineering; Physics and Astronomy;

    Abstract : This literature review investigates and evaluates different strategies to improve InGaN-based light emitting diodes (LED) by analyzing published theoretical and experimental studies. The issues of non-uniform carrier distribution, piezoelectric polarization fields and poor wave function overlap can be mitigated by the use of InGaN barriers and substrates as well as staircase designs for quantum wells (QW).

  6. 15. Concrete 3d printer

    University essay from Lunds universitet/Innovation

    Author : Lars Anell; [2015]
    Keywords : concrete 3d printer product development; Technology and Engineering;

    Abstract : In this project the aim was to design a concrete 3d printer. This report focuses on the extruder part of the printer and the printing material. The basic principle of 3d printing is that it is an additive manufacturing technique, on the contrary to the traditional subtractive manufacturing techniques. READ MORE
