  1. 6. Characterization of selective solar absorbers : Experimental and theoretical modeling

    Författare :Tuquabo Tesfamichael; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : This thesis deals with the preparation, optical characterization and analyses of experimental work and theoretical modeling on selective solar absorbers used in solar thermal collectors. The overall goal has been to obtain efficient absorbers by optimizing the optical properties, and to improve their durability using cost-effective techniques. LÄS MER

    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

  4. 8. Wood hydrolysate Barriers

    Författare :Anas Ibn Yaich; Ulrica Edlund; Ann-Christine Albertsson; Margaretha. Söderqvist-Lindblad; Inger Odnevall-Wallinder; KTH; []
    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.

  5. 9. Applications of Si1-xGex alloys for Ge devices and monolithic 3D integration

    Författare :Konstantinos Garidis; Per-Erik Hellström; Mikael Östling; Sten Vollebregt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon; germanium; epitaxy; selective; pn junction; germanium on insulator; GOI; Ge PFET; bonding; monolithic; sequential; three dimensional; 3D; low temperature; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : As the semiconductor industry moves beyond the 10 nm node, power consumption constraints and reduction of the negative impact of parasitic elements become important. Silicon germanium (Si1−xGex) alloys have been used to amplify the performance of Si based devices and integrated circuits (ICs) for decades. LÄS MER
