  1. 1. Desalination of Archaeological Iron Objects in Vacuum

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Aleksi Pienimäki; [2023-12-13]
    Nyckelord :Archaeological iron; desalination; vacuum;

    Sammanfattning : This work investigates the efficiency of commercially available vacuum containers as a physical deoxygenation method for desalination solutions for archaeological iron. Other factors are investigated as well, such as the effect of cleaning the objects of their corrosion crusts before treatment and drying them between subsequent treatment baths. LÄS MER

  3. 2. Analysis of Process Technologies to Preserve Berries

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

    Författare :Jose Abraham Zamudio Pedraza; [2022]
    Nyckelord :berry processing; freezing; drying; lyophilization; microwave vacuum drying; osmotic dehydration; environmental impact; food engineering; Agriculture and Food Sciences;

    Sammanfattning : From all the wild berries that grow in Sweden only 2-5% is utilized (RISE, 2022). The United Nation has 17 goals for sustainable development, and many of those goals are related to sustainable food production (United Nations, 2022). LÄS MER

  4. 3. Ultrasonic Assisted Drying and its Effect on 3D Printability of Minced Beef and Other Foods

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

    Författare :Viktor Lindström; [2020]
    Nyckelord :Drying; Convection drying; Ultrasound; Ultrasonic drying; 3D-Printing; 3D-Printability; Food; Meat; Beef; Food technology; Livsmedelsteknologi; Technology and Engineering;

    Sammanfattning : The aim of this master thesis project was to investigate the impact on drying kinetics of ultrasound during air drying by a new ultrasonic transducer, on which a patent application has been filed by CSIRO. Convection drying using hot air is currently the conventional method of drying in the industry due to its simplicity and low cost. LÄS MER

  5. 4. Hållbar pappersproduktion : Processoptimering via datasimulering

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Mohamed Haitham Alnafee; [2020]
    Nyckelord :;

    Sammanfattning : The purpose with this work is to increase the understanding about the energy consumed in papermaking, by combining existing calculation models and calculations, that gives the outgoing moisture rate and the needed energy for unit operations, vacuum dewatering and wet pressing, as well as a model for frictions that occur when different number of suction boxes are used. The moisture ratio that becomes the best of the first dewatering and then the pressing is then the decisive factor for energy required in the drying section, to dry off the remaining water. LÄS MER

  7. 5. Nanocellulose surface functionalization for in-situ growth of zeolitic imidazolate framework 67 and 8

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Beyar Abdulla; [2020]
    Nyckelord :Zeolitic Imidazolate Framework; ZIF-8; ZIF-67; CNF@MOF; CNF@ZIF; TEMPO CNF; Nanomaterials; Nanocomposites; Metal-Organic Framework; Biopolymers;

    Sammanfattning : This master’s thesis was conducted at the Department of Nanotechnology and Functional Materials at Ångström Laboratory as part of an on-going project to develop hybrid nanocomposites from Cladophora cellulose and a sub-type of metal-organic frameworks; zeolitic imidazolate frameworks (ZIFs). By utilizing a state-of-the-art interfacial synthesis approach, in-situ growth of ZIF particles on the cellulose could be achieved. LÄS MER
