  1. 6. Red Glass Coloration : a Colorimetric and Structural Study

    Författare :Torun Bring; Lars Kloo; Alicia Duran; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : Syftet med detta arbete har varit att försöka hitta alternativ till det kadmiumbase¬rade röda pigment som används idag. Detta har gjorts genom att delvis under¬söka kombinationer av grundämnen som i litteraturen finns omnämnda som röda glaspigment, delvis genom att försöka förbättra och underlätta produktionen av redan kända, men problematiska pigment.

    Sammanfattning : This thesis focuses on Peter Nilson’s (1937-1998) science fiction texts, and particularly on how narrative themes and structures in these texts are related to science as well as to the literary tradition of science fiction (SF). The primary texts are the novels Arken (The Ark, 1982), Äventyret (The Adventure, 1989), Rymdväktaren (The Space Guard, 1995), Nyaga (1996) as well as the short story “Kvinnan som ville ha barn med döden” (The Woman Who Wanted a Child With Death, 1987).

  4. 8. Annealed Glass Failure Modelling : A Weakest-Link Approach with Statistical Analysis

    Författare :David Kinsella; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glass strength; structural glass; Weibull distribution; weakest-link system; statistical analysis; experimental tests; numerical modelling; finite element method; fracture mechanics;

    Sammanfattning : Novel and increased use of glass in building construction has been made possible, as a result of methods of mass production introduced during the 20th century and advanced computational structural analyses. With modern use of glass structures, a range of demands emerge which need to be addressed in the strength design process. LÄS MER

  7. 10. Structural Investigations of Complex Glasses by Solid-state NMR

    Författare :Ekaterina Leonova; Mattias Edén; Robin Harris; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glass; glass structure and properties; NMR; magic angle spinning; chemical shift; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : This PhD thesis presents structural investigations of amorphous inorganic materials: oxide and oxynitride glasses and mesoporous bioactive glasses (MBGs), by solid-state Nuclear Magnetic Resonance (NMR). Lanthanum oxide and oxynitride [La-Si-(Al)-O-(N)] glasses have a large number of potential applications due to their physical properties. LÄS MER
