    Nyckelord :Materials science; solar; thermal; absorber; selective; chemical; Materialvetenskap;

    Sammanfattning : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. LÄS MER

  2. 2. Spectrally Selective Solar Absorbing Coatings Prepared by dc Magnetron Sputtering

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Shuxi Zhao; Uppsala universitet.; [2007]
    Nyckelord :Materials science; spectrally selective surface; solar energy; magnetron sputtering; thin film; Materialvetenskap;

    Sammanfattning : Spectrally selective solar absorber using composite Ni-NiO as coating materials was studied. Samples were prepared by dc magnetron sputtering unit named Rulle, which is a miniature copy of an industrial roll-coater unit. LÄS MER

  3. 3. Characterization of selective solar absorbers Experimental and theoretical modeling

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : Semiconductor wafer bonding has been a subject of interestfor many years and a wide variety of wafer bonding techniqueshave been reported in literature. In adhesive wafer bondingorganic and inorganic adhesives are used as intermediatebonding material. LÄS MER

  5. 5. Wood hydrolysate Barriers

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Anas Ibn Yaich; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; xylan; hemicellulose; layered silicates; oxygen barrier; packaging; film; coaing; birch.;

    Sammanfattning : Wood hemicellulose is an abundant but fairly unexploited renewable feedstock. Recent studies have shown that hemicelluloses have a large potential for use in the food packaging industry as a sustainable alternative to the conventional oxygen-barrier materials used today. LÄS MER
