  1. 1. Innovative process solutions towards recycling of salt cake from secondary aluminum smelting

    Författare :Peng Li; Lidong Teng; Sankaran Subramanian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal diffusivity; Model; Solubility; CO2; AlN; Crystals; Hydrolysis; Enhance; Hinder; Leaching; Absorption; Synthesis; SiMgAlON; Oxidation; Arctan; Activation energy; Mullite; Liquid; Crystallization.; SRA - Production; SRA - Produktion;

    Sammanfattning : To offer better solutions for the recycling of salt cake from secondary aluminum melting, several innovative investigations were carried out based on hydrometallurgical and pyrometallurgical views.Thermal diffusivity measurements as a function of temperature on salts-Al composites having various compositions (0, 2, 4, 6, 8, 10, 12wt pct metallic Al) were carried out.

  3. 2. Absorption non-uniformity characterisation and its impact on flexographic ink distribution of coated packaging boards

    Författare :Sofia Thorman; Li Yang; Göran Ström; Magnus Lestelius; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid absorption; Absorption non-uniformity; Characterisation; Measurement technique; Print Mottle; Flexography; Coated packaging boards; Chemical Engineering; Kemiteknik;

    Sammanfattning : There are high demands on flexographic print quality to be sufficiently high and consistent in order to create a competitive packaging. At the same time the production efficiency need to be high. Printers thus need to achieve the same quality every time and quickly start-up new printing jobs. LÄS MER

  4. 3. Quantum Nuclear Dynamics in Resonant X-ray Scattering of Gas-Phase and Liquid Systems

    Författare :Vinicius Vaz da Cruz; Victor Kimberg; Faris Gel'mukhanov; Hans Ågren; Philippe Wernet; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant inelastic X-ray scattering; X-ray absorption; water; methanol; CO; rotational doppler effect; recoil; wave packet; non-Franck-Condon effect; ultra-fast molecular dissociation; potential energy surface; hydrogen bond; liquid; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : This thesis focuses on the role of the nuclear degrees of freedom in X-ray induced molecular processes. An important part of it is devoted to establishing theoretical principles to model and interpret high-resolution resonant X-ray scattering experiments in gases and liquids. LÄS MER

  5. 4. The Compression/Absorption Heat Pump Cycle - System Simulations

    Författare :Lena Åhlby; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compression; refrigerant mixture; absorption; NH3 H2O; NH3 H2O-LiBr;

    Sammanfattning : From the results presented in this thesis it is clear that the compression/absorption heat pump cycle offers several advantages over other types of heat pumps. In many cases it gives a higher or equally high COP compared with the single-fluid compression heat pump but also the smaller SCD (i.e. LÄS MER

  7. 5. Where did the ink go? : The effect of liquid absorption on ink distribution in flexography

    Författare :Sofia Thorman; Li Yang; Magnus Lestelius; Martti Toivakka; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexographic printing; print mottle; ink trapping; absorbency; absorption non-uniformity; water-interference mottle; Chemical Engineering; Kemiteknik;

    Sammanfattning : The appearance of a print is affected by the individual ink layers. If the ink is unevenly distributed on the substrate it lowers the quality. This thesis puts focus on how the liquid absorbency of a coated substrate impacts on the ink distribution in flexographic printing. LÄS MER
