    Author : Simon Lindroth [formerly Tyrberg]; Uppsala universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; Measurement systems; Marine technology; Energy conversion; Renewable energy; Energy absorption; Wave resource; Oceanic engineering; Linear generators; Point absorbers; Sea trials; Camera systems; Accelerometers; Offshore experiments; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. READ MORE

  2. 2. Exploring Devices for Molecular Solar Thermal Energy Storage Systems

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Zhihang Wang; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy storage; norbornadiene quadricyclane photoswitches; photochromic molecule; Solar energy; energy conversion; dihydroazulene vinylheptafulvene photoswitches;

    Abstract : The sun is considered to be one of the most abundant and renewable sources of energy. During recent last decades, technologies for solar energy capture and storage have been significantly investigated. An attractive way to store solar light, is to use photochromic molecules that can capture and store solar energy in chemical bonds. READ MORE

  3. 3. Aspects of oral implant technology and osseointegration

    University dissertation from Malmö universitet, Faculty of Odontology

    Author : Rainde Naiara Rezende de Jesus; Malmö University.; [2019]
    Keywords : ODONTOLOGY; ODONTOLOGI; Medicine; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

    Abstract : Implant rehabilitation of edentulous patients is a predictable treatment with high long-term survival rates (90-95%) reported for the major dental implant systems after 5-10 years in function. Throughout recent years, different materials, implant surface technologies, macrodesigns, and surgical techniques have been developed to enhance osseointegration and lessen treatment timeframes, for example allowing immediate or early functional loading in patients with reduced bone density.
