  1. 1. Multicomponent TiNbCrAl nitride films produced by DCMS and HiPIMS

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Grzegorz Sadowski; [2021]
    Keywords : High entropy nitrides; thin film; HiPIMS; hardness;

    Abstract : High entropy alloys (HEAs) are made of at least five principal elements in near-equimolar proportions. The vast number of possible alloys and unconventional combinations of properties are the main benefits of HEAs. Ti, Nb, Cr, Al and N were chosen in order to create a hard, corrosion resistant coating with good thermal stability. READ MORE

  3. 2. 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

  4. 3. Modeling of carbon plasma discharges in high-power impulse magnetron sputtering

    University essay from Linköpings universitet/Plasma och ytbeläggningsfysik

    Author : Henrik Eliasson; [2021]
    Keywords : ;

    Abstract : Diamond like carbon (DLC) is a metastable state of amorphous carbon that has very important and wide-ranging thin film applications. DLC has a strong resemblance to pure diamond and exhibits many traits of real diamond, like mechanical hardness and chemical inertness, but with a drastically lower deposition cost. READ MORE

  5. 4. Chemical analysis of hazardous substances in permanent tattoo inks available on the market

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Anna Bevin; An Na Lay; Daniel Ullmark; Jessika Hagman; [2020]
    Keywords : Tattoo inks; tattoos; metals; pigments; skin; matrix assisted laser desorption ionization time of flight mass spectrometry; inductively coupled plasma mass spectrometry; mass spectrometry; allergens; dyes;

    Abstract : As permanent tattoos are becoming more popular and common, an increased number of allergic reactions to tattoos is reported. The purpose of this project was to analyze tattoo inks for hazardous substances, and whether they comply to current Swedish and European legislative requirements. READ MORE

  6. 5. Design and Evaluation of a 3D Printed Ionization Chamber

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Caroline Boström; Olivia Messler; [2019]
    Keywords : 3D printing; Ionization chamber; Gas-filled detectors;

    Abstract : Ionizing radiation is often used within medicine for diagnosis and treatments. Because ionizingradiation can be harmful to the body, it is important to know how it affects the tissue. Dosimetryis the study of how ionizing radiation deposits energy in a material. READ MORE
