  1. 1. Exploration of Graphene-like 2D Materials for Energy Management and Interface Enhancement Applications

    Författare :Ya Liu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Application; Graphene-like 2D materials; Interface Enhancement; Energy Management;

    Sammanfattning : Ever since the discovery of graphene in 2004, graphene-like 2D materials and their derivatives have attracted extensive investigations because of their exceptional physical and chemical properties. At present, the study of graphene-like 2D materials is at a stage where most of their outstanding physical and chemical properties have been discovered, but the technology for incorporating them into practical commercial products is rarely revealed.

    Sammanfattning : The internationalization of SMEs has been recognized as one of the important paths to growth in SMEs. However, internationalization is also a resource and competence-demanding process. LÄS MER

  4. 3. Multiscale materials design of hard coatings for improved fracture resistance and thermal stability

    Författare :Phani Kumar Yalamanchili; Magnus Odén; Naureen Ghafoor; Emilio Jiménez-Piqué; Jon Molina; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Physical vapor deposited hard coatings comprised of cubic (c) transition metal (TM)-Al-N, and (TM)-Si-N are the current workhorse materials for a large number of metal cutting and wear resistant applications to fight against the extreme conditions of temperature and stress simultaneously. In spite of a high degree of sophistication in terms of material choice and microstructural design, a lower fracture resistance and limited thermal stability of the coatings remains a technological challenge in the field.

  5. 4. Mejora y evolución de los protocolos de congelación de eyaculados de oso pardo (Ursus arctos)

    Författare :Manuel Alvarez-Rodriguez; Paulino de Paz Cabello; Luis Anel Rodríguez; Spain Facultad de Ciencias Biologicas y Ambientales University of Leon; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : La situación crítica del oso pardo (Ursus arctos) en España plantea la necesidad de aplicar diferentes estrategias de conservación, dentro de las cuales tiene especial relevancia la creación de un banco de recursos genéticos. La eficacia de esta herramienta depende, entre otros factores, de la adaptación específica de los protocolos de congelación espermática ya existentes y que permitan el almacenamiento eficaz de los espermatozoides del oso pardo en un banco de germoplasma.
