Assessment and Validation of the Engineering Performance of Central Venous Catheters (CVCs) and the Impact of Hemocompatible Thin Film Coatings
Fossum, Maren Kirknes (2022:338;2022:338, Doctoral thesis, 2022)Biomaterials used in implanted medical devices must fulfil a stringent set of requirements, and both the bulk - and the surface properties of a device material must be considered when evaluating the engineering performance ... -
Ceramic Foam Filters (CFFs) for Aluminium Melt Filtration - Stability, Compression, and Performance
Bergin, Are (Doctoral theses at NTNU;2022:260, Doctoral thesis, 2022)During aluminium production, the molten aluminium will necessarily include a certain amount of impurities, including non-metallic inclusions, i.e., solid objects immersed in the melt. These inclusions are known to be ... -
Changes in Material Properties of Silicone and PVC Tracheostomy Tubes – In-vitro Prediction of Medical Device Material Performance In-vivo
Stenersen, Rebekka (Master thesis, 2022)Abstract will be available on 2023-06-09 -
Electromagnetically Enhanced Priming of Ceramic Foam Filters
Fritzsch, Robert (Doctoral thesis at NTNU;2016:250, Doctoral thesis, 2016)Impurities in aluminium can cause detrimental physical and chemical inhomogeneity in the final products, as well as potentially catastrophic failures. Hence, one of the key aspects during production of aluminium and its ... -
Evaluation of Filtration Efficiency of Ceramic Foam Filters (CFF) Using a Hydraulic Water System
Hassanabadi, Massoud; Akhtar, Shahid; Bilek, Petr; Aune, Ragnhild E. (Journal article; Peer reviewed, 2018)The filtration efficiency of Ceramic Foam Filters (CFFs) of grades 50 and 65 has been quantitatively evaluated using a hydraulic water system. Distilled water seeded with Polystyrene Microsphere particles with a distribution ... -
Formation of Hard Grey Scale (HGS) on the Surface of a Cold-finger in the Aluminium Production Industry
Clos, Daniel Perez (Doctoral theses at NTNU;2021:183, Doctoral thesis, 2021)The present work has investigated the formation mechanisms of Hard Grey Scale (HGS) in a duct transporting the off-gas from aluminium production pot cells to the Gas Treatment Centre (GTC). For that purpose, a cooled fouling ... -
Grain Refinement of Commercial EC Grade 1370 Aluminium Alloy for Electrical Applications
Hassanabadi, Massoud; Akhtar, Shahid; Arnberg, Lars; Aune, Ragnhild E. (Journal article; Peer reviewed, 2018)The purpose of the present study was to investigate the effect of different grain refiners’ additions on structure and electrical conductivity of commercially electrically conductive (EC) grade 1370 aluminium alloy. A ... -
Parametric Study of Molten Aluminium Oxidation in Relation to Dross Formation at Laboratory and Industrial Scale
Solem, Cathrine Kyung Won (Doctoral theses at NTNU, 2022:341, Doctoral thesis, 2022)Aluminium (Al) white dross, classified as a hazardous waste, is a heterogeneous mixture of metallic Al, oxides, and non-metallic compounds (NMC) originating from the primary production route of Al. Over the past few decades, ... -
Verification of Experimentally Determined Permeability and Form Coefficients of Al2O3 Ceramic Foam Filters (CFF) at High and Low Flow Velocity Using a CFD Model
Hassanabadi, Massoud; Kennedy, Mark W.; Akhtar, Shahid; Aune, Ragnhild E. (Journal article, 2018)Filtration using Ceramic Foam Filters (CFFs) is a method widely used to separate inclusions from molten aluminium. In the present work, the specific permeability and form drag coefficients of nominal 50 mm thick commercial ... -
Zr-Based Metallic Glasses as Biomaterials: Design, Production and Characterization
Tabeshian, Ali (Doctoral theses at NTNU;2019:2, Doctoral thesis, 2019)Metallic Glasses (MGs) have a unique non-crystalline structure which is the main reason for their extraordinary properties, e.g. high hardness, good wear resistance, high corrosion resistance, as well as the ability to be ...
