  1. 1. Open-Framework Germanates : Synthesis, Structure, and Characterization

    Författare :Andrew Kentaro Inge; Xiaodong Zou; Anthony Cheetham; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Open-framework; zeolites; germanates; porous materials; crystallography; hydrothermal synthesis; crystal structure; Structural Chemistry; strukturkemi;

    Sammanfattning : Novel open-framework germanates and open low-dimensional structures were synthesized and characterized. Their crystal structures were solved by single crystal X-ray diffraction or X-ray powder diffraction combined with other techniques. LÄS MER

  3. 2. Material virtualities : Approaching online textual embodiment

    Författare :Jenny Sunden; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Embodiment; body; cyberfeminism; cyborg; subjectivity; virtuality; materiality; MUD; MOO; cybercultural studies; digital textuality; online ethnography; poststructuralist literary theory; queer theory; online interaction; Diskursanalys; språksociologi; cyberspace; queerteori; virtuell verklighet; MUD; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : While the Internet is often presented as a disembodied medium, various forms of bodily presence are continually introduced when people meet online. This study explores notions of embodiment in a particular text-based virtual world (here called WaterMOO) by investigating how bodies- always sexually specific- are created and rendered meaningful in online textual practices.

  4. 3. Modelling Aspects in Forming and Welding of Nickel-Base Superalloys

    Författare :Lluís Pérez Caro; Mats Oldenburg; Eva-Lis Odenberger; Juan Carlos Cante Teran; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alloy 718; Haynes 282; cold forming; hot forming; material characterization; GISSMO; welding; heat treatment; manufacturing chain; springback; shape distortions; dynamic strain aging; DSA; microstructure; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry because of major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the weight of vehicles while increasing the efficiency of the engine. LÄS MER

  5. 4. Tunning Multicolor Light Emission in Lead-free Materials

    Författare :Weidong Cai; Feng Gao; Jiajun Qin; Letian Dou; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multicolor light emission; Chiral material; Color change under humidity; Lead-free organic and inorganic material; Incorporation of extra emission center; Leadfree double perovskite; Co-doping; Flerfärgad ljusemission; Kiralt material; Färgförändring under fukt; Blyfritt organiskt och oorganiskt material; Inkorporering av extra emissionscenter; Blyfri dubbel perovskit; Samdopning;

    Sammanfattning : Perovskites are a class of compounds with the general formula ABX3 and becoming increasingly attractive recently. Because this kind of material possesses various advantages such as abundant raw materials, easy synthesis, excellent photoelectric properties, and short production process. LÄS MER

  7. 5. The effect of microstructural features, defects and surface quality on the fatigue performance in Al-Si-Mg Cast alloys

    Författare :Toni Bogdanoff; Ehsan Ghassemali; Salem Seifeddine; Anders E.W. Jarfors; Ru Peng; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum-Silicon alloys; defects; material characterization; fatigue performance; digital image correlation;

    Sammanfattning : Global warming is driving industry to manufacture lighter components to reduce carbon dioxide (CO2) emissions. Promising candidates for achieving this are aluminium-silicon (Al-Si) cast alloys, which offer a high weight-to-strength ratio, excellent corrosion resistance, and good castability. LÄS MER
