  1. 1. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Johan Ranstad; [2023]
    Nyckelord :Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Sammanfattning : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. LÄS MER

  3. 2. In vitro study of Biodegradation in Mg-alloys by Isothermal Calorimetry

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Prasad Rajendra Kekare; Akshat Kulkarni; [2021]
    Nyckelord :Isothermal Calorimetry; Degradation of Mg Alloys; Supersaturated solid solution SSSS ; Corrosion rate; Aqueous corrosion.; Technology and Engineering;

    Sammanfattning : Magnesium corrosion in an aqueous environment is a multi-layer, complex process. A literature survey shows significant gaps and the modelling work reported indicates a lack of clarity in understanding the corrosion process. LÄS MER

  4. 3. Degradation of model biomedical Mg alloys in aqueous media

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Max Viklund; [2020]
    Nyckelord :Magnesium; alloys; bio-materials; implants; corrosion; isothermal calorimetry; Technology and Engineering; Medicine and Health Sciences;

    Sammanfattning : This project investigates the influence of alloying elements, heat treatment and corrosion medium on the corrosion rates of three magnesium alloys Mg-5Zn, Mg0.27Ca, and Mg-0.27Ca-5Zn for use in bio-medical applications. LÄS MER

  5. 4. The Effect of Using DMSO as a Cosolvent for Ligand Binding Studies

    Master-uppsats, Lunds universitet/Biofysikalisk kemi

    Författare :Simon Birgersson; [2019]
    Nyckelord :Galectins; Nuclear Magnetic Resonance; NMR; Biophysical Chemistry; Relaxation; CPMG; ITC; Biofysikalisk Kemi; Kärnmagnetisk resonans; Technology and Engineering; Chemistry; Biology and Life Sciences;

    Sammanfattning : DMSO sees common application as a solvent for studies of synthetic molecules in biological systems, in fields such as drug design. Despite this, the possibility and nature of solvent interactions with both synthetic ligand and their target macromolecules is widely unexamined. LÄS MER

  7. 5. Organic Fillers for Solid Rocket Fuel

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Viktor Bladholm; [2018]
    Nyckelord :Hybrid rocket propellant; fuel formulation; organic fillers; hexamine; fluorene; anthracene; 1; 4-dicyanobenzene; Hybridraketer; bränsleformulering; organiska additiv; hexamin; fluoren; anthracen; 1; 4-dicyanobenzen;

    Sammanfattning : Idag är de vanligaste använda raketerna flytande-bränsle- och fast-bränsle- raketer. Flytande-bränsle-raketer har fördelen att det kan manövreras men de har en komplex design och problem med förvaring. Fast-bränsle-raketer har en enkel design och kan förvaras men de har en miljöpåverkan och bränslet kan vara svårhanterligt. LÄS MER
