  1. 11. Optics of coated paperboard : Aspects of surface treatment on porous structures

    Författare :Erik Bohlin; Caisa Johansson; Magnus Lestelius; Per Edström; Per-Åke Johansson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Calendering of coated and uncoated paper is widely used to enhance optical properties such as gloss and print quality. The aim of this thesis is to characterize coatings and prints, and to validate models using experimental results from optical measurements of physical samples. Calendering of coated paper often leads to a brightness decrease. LÄS MER

  3. 12. Microcontact Printing for Protein Microarray Applications

    Författare :Ye Zhou; Per Claesson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis introduces the microcontact printing (μCP) method to pattern and tailor the desired substrates for protein microarray applications. The ink molecules used to create the patterns, hydrophobic barriers, are tetraalkyl ammonium salt, polycationic polymers and oligo(ethylene glycol)-terminated self-assembled monolayers. LÄS MER

  4. 13. Compression uniformity measurements on coated anduncoated paper surfaces

    Författare :Isabel Endres; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Paper is exposed to compressive stresses at several occasions in its production process and in subsequent printing operations. In the press section of a paper machine, the fibre web is mechanically dewatered by compression. LÄS MER

  5. 14. Measuring and modelling light scattering in paper

    Författare :Niklas Johansson; Per Edström; Mattias Andersson; Magnus Neuman; Jon Yngve Hardeberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; goniophotometry; anisotropy; angle resolved light scattering; reflectance measurements; turbid media;

    Sammanfattning : Avhandlingen behandlar de teoretiska och praktiska aspekterna av att använda spektrala vinkelupplösta reflektansmätningar för optisk karakterisering av fiberbaserade material såsom papper och kartong. En spektral goniofotometer används för att mäta det reflekterade ljusets vinkelfördelning. LÄS MER

  7. 15. Structured Ammonia Carriers for Selective Catalytic Reduction

    Författare :Zhejian Cao; Farid Akhtar; Andreas Kaiser; Peizhong Feng; Louise Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ammonia; SCR; NOx; graphene network; zeolite; MOF; Engineering Materials; Materialteknik;

    Sammanfattning : Air quality has been one of the long-term focuses in society and has raised people’s concern regarding its amelioration in the post coronavirus disease 2019 (COVID-19) pandemic era. Nitrogen oxides (NOx), including NO and NO2, as one of the most harmful air pollutants, have been stringently monitored in most countries due to their devastating impact on the environment and human health.
