  1. 16. Printability and Ink-Coating Interactions in Inkjet Printing

    Författare :Erik Svanholm; Göran Ström; Gunnar Engström; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; inkjet; print quality; printability; pigment; silica; polyvinyl alcohol; colorant; ink absorption; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER

  3. 17. Studies on Diesel sprays under non-reacting and reacting conditions

    Författare :Chengjun Du; Chalmers tekniska högskola; []

  5. 19. Photocatalysis for Indoor Air Cleaning : In situ FTIR and DFT Study of Acetaldehyde Photo-Oxidation on TiO2 and Sulfate-Modified TiO2

    Författare :Bozhidar Stefanov; Lars Österlund; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TiO2; acetaldehyde; crotonaldehyde; dimer; adsorption; DFT; FTIR; photocatalysis; micro-kinetic modeling; acid–base properties; surface functionalization; Solid State Physics; Fasta tillståndets fysik; Materialvetenskap; Materials Science;

    Sammanfattning : Acetaldehyde is among the group of VOC’s causing the so-called "sick building" syndrome. WHO has estimated that this problem, related to the indoor air-quality, affects one third of all buildings worldwide. TiO2 is an attractive material for the photocatalytic removal of VOC’s in the indoor environment. LÄS MER

  7. 20. Synthesis and characterization of Pd nanoparticles for plastic plasmonic sensing applications

    Författare :Alicja Stolas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasmon resonance; hydrogen sensing; polymers; nanoparticles;

    Sammanfattning : It is well known that hydrogen mixed with air forms a highly flammable mixture. There is an urgent need for selective and accurate sensors, since hydrogen very often serves as a fuel or energy storage medium. Given the fact that even the smallest leak can lead to an explosion, it is very important for sensors to be reliable and safe, i.e. LÄS MER
