  1. 1. Fastläggning av arsenik med nollvärt järn i mikrostorlek : Uppföljning av ett pilotskaleförsök

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Frida Aronsson; [2023]
    Nyckelord :contaminated soil; arsenic; zero-value iron; mZVI; pilot test; pilot study; förorenad mark; arsenik; nollvärt järn; mZVI; pilotförsök; pilotstudie;

    Sammanfattning : Land contaminated with arsenic is a major problem as arsenic is toxic and poses a major health risk to both humans and animals. There are several remediation methods, both in-situ and ex-situ, to prevent and deal with pollution problems in different ways. LÄS MER

  3. 2. Koncept för att testa däckslitage

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Philip Missuna; [2023]
    Nyckelord :Microparticles; Tribometer; Tire; Camber; Däck; Mikropartiklar; Tribometer; Cambervinkel;

    Sammanfattning : Denna rapport omfattar utveckling av en rigg för att testa slitage av däck. Detta sker genom omkonstruktion av existerande pinne-på-skivatribometer rigg som man finner hos Kungliga Tekniska Högskolan. LÄS MER

  4. 3. The effect of lactose fines, magnesium stearate, choice of mixer and mixing process on the performance of adhesive mixtures for inhalation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Gabriela Ponce Aparicio; [2023]
    Nyckelord :High shear mixing; low shear mixing; lactose fines; coating agent; budesonide; mixing energy; dry powder inhaler; carrier-based formulations; mixing time; adhesive mixtures; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Dry powder inhaler (DPI) formulation is a major area of interest since they are employed by the healthcare system to treat relevant chronic diseases like asthma. Previous research has established that the manufacturing process and formulation composition are key for the active pharmaceutical ingredient to reach the lungs and achieve therapeutic effects.

  5. 4. Color halftoning methods for screen printing and special effect pigments : Reproducing iridescent colors

    Master-uppsats, Linköpings universitet/Institutionen för teknik och naturvetenskap

    Författare :Alfred Rundquist; [2023]
    Nyckelord :iridescence; color; halftoning; screen; printing; ink; special; effect; pigments; media technology; simulation; iriserande; färg; rastrering; metod; screentryck; silkscreentryck; raster; färgreproduktion; simulering;

    Sammanfattning : Iridescence is the property that makes colors vary by angle of observation. Technology has made it possible to print with ink that has this anisotropic property. The ink that is used contains microparticles and therefore only specific printing methods can be used, for example screen printing. LÄS MER

  7. 5. Utveckling av Polydimetylsiloxan-Mikropartiklar för Biomedicinsk NMR

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Mohammad Al-Sultani; Josef Djärf; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Nuclear magnetic resonance spectroscopy is a technique for identifying molecular structures, compositions etc. and is widely used in many life science research fields. The purpose of this project is to synthesize PDMS microparticles with a magnetic susceptibility matching water, which makes them applicable for use in NMR of biological samples. LÄS MER
