  1. 1. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Mona Koder Hamid; [2020]
    Nyckelord :clay; molecular dynamics simulations; physical chemistry; fysikalisk kemi; theoretical chemistry; teoretisk kemi; Chemistry;

    Sammanfattning : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

  2. 2. Benchmarking Physical Properties of Water Models

    Kandidat-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Tomas André; [2019]
    Nyckelord :Water Models; Molecular Dynamics; Properties of water; MD; Simulation; GROMACS;

    Sammanfattning :     Water is a fundamental part of life as we know it, and by that also a fundamental for biology, chemistry, and parts of physics. Understanding how water behaves and interacts is key in many fields of all these three branches of science. LÄS MER

    Sammanfattning : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. LÄS MER

  4. 4. Adsorption of lysozyme on Silica Surfaces and Specific ion effects

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Guillem Onyos de Plandolit Ruiz; [2019]
    Nyckelord :Ellipsometry; mesoporous silica nanoparticles; surfaces; physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : Biomedical application of nanoparticles is largely associated to their fate in biological media which, in fact, is related to their surface properties. Surface functionalitzation plays a key role in determining biodegradation, cytotoxicity and biodistribution through interactions which may be meditated by the macromolecules occurring in biological media.

  5. 5. Effekten av gammastrålning på svällningskapaciteten för bentonitlera

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

    Författare :Kevin Chung; [2019]
    Nyckelord :Bentonitlera; Gammastrålning; Svällning; Vattenupptag;

    Sammanfattning : SKB (Svensk Kärnbränslehantering AB) planerar att förvara utbränt kärnbränsle i berggrunden, KBS-3 metoden. Enligt den s.k. KBS-3 metoden ska förvaret bestå av tre skyddsbarriärer, kopparkapslarna, bentonitleran och urberget. LÄS MER
