  1. 1. Properties of Modern Rendering Systems based on Mineral Binders

    Författare :Carl-Magnus Capener; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymers; mortar; rendering; properties; microstructure; admixtures; chemistry;

    Sammanfattning : Composite mineral–organic materials and in particular cement-organic materials are increasingly used in today’s construction applications and civil engineering projects. Polymer-modified render is a material that possesses several properties superior to conventional renders, such as better workability, crack resistance, adhesion to substrate and flexural strength.

  3. 2. Investigations on the Oxidation of Iron-chromium and Iron-vanadium Molten Alloys

    Författare :Haijuan Wang; Seshadri Seetharaman; Ashok Lahiri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxidation; High-alloy steelmaking; Retention; CO2-O2; Fe-Cr melt; Fe-Cr-C melt; Fe-V melt; Vanadium containing slags; Kinetics; Thermodynamics properties.; Metallurgical process engineering; Metallurgisk processteknik; Materials science; Teknisk materialvetenskap;

    Sammanfattning : With the progress of high alloy steelmaking processes, it is essential to minimize the loss of valuable metals, like chromium and vanadium during the decarburization process, from both economic as well as environmental view points. One unique technique to realize this aim, used in the present work, is the decarburization of high alloy steel grades using oxygen with CO2 in order to reduce the partial pressure of oxygen. LÄS MER

  4. 3. Pharmaceutical cocrystals : formation mechanisms, solubility behaviour and solid-state properties

    Författare :Amjad Alhalaweh; Peter York; Luleå tekniska universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; crystal engineering; cocrystal; formation; solubility; pH; dissolution; surface properties; solid-state properties; Health Science; Hälsovetenskap;

    Sammanfattning : The primary aim of pharmaceutical materials engineering is the successful formulation and process development of pharmaceutical products. The diversity of solid forms available offers attractive opportunities for tailoring material properties. LÄS MER

  5. 4. Studies of an elusive element : processes that influence the net retention of mercury in lake sediments and peatlands

    Författare :Johan Rydberg; Richard Bindler; Carl Lamborg; Umeå universitet; []
    Nyckelord :Mercury; retention; lake sediments; peatlands; environmental archives; sedimentation; diagenesis; vegetation; permafrost; Environmental Science; miljövetenskap;

    Sammanfattning : Because of its toxic nature mercury is a threat to both wildlife and human health, and thus, it is an element of concern in the environment. Currently much of the mercury emitted to the atmosphere is derived from anthropogenic sources – both direct emissions and re-emission of already deposited anthropogenic mercury. LÄS MER

  7. 5. Absorbent Materials from Kraft Pulp

    Författare :Fredrik Wernersson Brodin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MFC; retention; foam; TEMPO oxidation.; absorption; Absorbent;

    Sammanfattning : Superabsorbent polymers (SAP) have, since being introduced in the 1980s, become an important constituent in hygiene products, such as disposable diapers. The design of disposable diapers has changed over the years and today thinner products can be produced partly because of the excellent absorption and retention properties of the petrochemical-based SAP.
