    Författare :Fredrik Eklund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbubbles; nanobubbles; ultrafine bubbles; digital holographic microscopy; nanoparticle tracking analysis;

    Sammanfattning : Gas bubbles smaller than 1 micrometre in water, commonly referred to as nanobubbles, is a growing field of research and innovation. Applications range from medical imaging and drug delivery to mining industry and environmental remediation. LÄS MER

  3. 7. Studies on the cold bonded briquettes of iron and steel plant by-products as burden material for blast furnaces

    Författare :Maneesh Singh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : During the various stages of iron & steel production a number of iron bearing by-products are generated. These by-products can be made into cement bonded agglomerates for use as burden material for blast furnaces. LÄS MER

  4. 8. Particle Engineering by Spherical Crystallization:Mechanisms and Influence of Process Conditions

    Författare :Jyothi Thati; Åke Rasmuson; Stephane Veesler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Benzoic acid; Solubility; Phase diagram; Physico- mechanical properties size distribution; particle morphology and crushing strength; elastic recovery; compressibility ; Chemical engineering; Kemiteknik;

    Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water as the anti-solvent. LÄS MER

  5. 9. The influence of solvent composition on crystal agglomeration of paracetamol

    Författare :Eva Ålander; KTH; []
    Nyckelord :paracetamol; solvent composition; agglomeration; image analysis; principal component analysis; agglomerate strength; interfacial energy;

    Sammanfattning : This thesis deals with the influence of solvent compositionon crystal agglomeration of paracetamol. Much work has beendone on characterisation of the crystalline product.Interfacial energies have also been determined for large singlegrown crystals. LÄS MER

  7. 10. Nanostructures Studied by Atomic Force Microscopy : Ion Tracks and Nanotextured Films

    Författare :Judit Kopniczky; Claes-Göran Granqvist; Lars Montelius; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; ion impact; surface tracks; electronic sputtering; WO3; nanoparticle; scanning probe microscopy; tapping mode; Fysik; Physics; Fysik;

    Sammanfattning : The work presented in this thesis concernes two sorts of nanostructures: energetic-ion-impact-induced surface tracks and gas-deposited WO3 nanoparticles. Our aims to characterise these nanostuctures and understand the physical principles behind their formation are of general interests for basic science as well as of the field of nanotechnology. LÄS MER
