1. 1. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

   University essay from Göteborgs universitet/Institutionen för kulturvård

   Author : Gabriella Zimmerman; [2023-11-07]
   Keywords : plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

   Abstract : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. READ MORE

3. 2. Synthesis and Characterization of Materials for Carbon Based Hybrid Asymmetric Supercapacitor Electrodes

   University essay from KTH/Tillämpad fysikalisk kemi

   Author : Avital Cherednik; [2023]
   Keywords : Supercapacitor; hybrid supercapacitor; metal oxide nanoparticles; carbon electrodes; ionic liquid; Superkondensator; hybrid superkondensator; metaloxid nanopartiklar; kolelektroder; jonvätska;

   Abstract : Superkondensatorer är energilagringsenheter som har uppmärksammats mer under det senaste decenniet. Några av de fördelar som dessa enheter har varit är lagring av hög effekttäthet, förlängda livscykler och snabba laddnings- och urladdningstider. READ MORE

4. 3. Varnishing of Fiber-based Closures

   University essay from Lunds universitet/Förpackningslogistik

   Author : Nisha Sunil David; [2023]
   Keywords : Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

   Abstract : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. READ MORE

5. 4. Developing an Ar milling process to improve the contact quality to InAs nanowires

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

   Author : Chris Mkolongo; [2023]
   Keywords : InAs nanowires; Argon milling; Technology and Engineering;

   Abstract : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). READ MORE

6. 5. Modelling Gas Flow Behaviour in Gas Atomizer

   University essay from KTH/Materialvetenskap

   Author : Aravind Senan Vasanthasenan Reji; [2022]
   Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

   Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.
