  1. 21. Super-resolution Luminescence Micro-Spectroscopy : A nano-scale view of solar cell material photophysics

    Författare :Aboma Merdasa; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; super-resolution microscopy; Single Molecule Spectroscopy; J-aggregates; perovskites; photophysics;

    Sammanfattning : Optical microscopy is a fundamental tool in a range of disciplines encompassed by the physical and biological sciences. At the dawn of this millennium, a break-through was made in optical microscopy where super-resolution methods emerged and declared imaging beyond the optical diffraction limit a possibility. LÄS MER

  3. 22. Gene Expression Changes and Brain Plasticity after Experimental Stroke

    Författare :Mattias Rickhag; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; apolipoprotein D; regeneration; brain ischemia; functional recovery;

    Sammanfattning : Stroke is the most common life-threatening neurological disease and ranks as the third leading cause of death in major industrialized countries. It is also the leading cause of serious long-term disability and about sixty percent of survivors have disabilities in their extremities. LÄS MER

  4. 23. Mitochondrial dysfunction and treatment strategies

    Författare :Shuba Krishnan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The mitochondria are essential for cellular energy production and are involved in many processes in the cells. The mitochondria contain their own DNA (mtDNA) that is vital for oxidative phosphorylation since it encodes enzymes of the respiratory chain. LÄS MER

  5. 24. In vitro and in vivo studies on biodegradable matrices for autotransplantation

    Författare :Carl-Johan Gustafson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :In vitro; in vivo; dermis; matrix; autotransplantation; culture; keratinocytes; urothelium; tissue engineering; PUUR; macroporous spheres ; guided tissue regeneration;

    Sammanfattning : Tissue engineering (TE), one of the most rapidly growing fields of life science, is an interdisciplinary area in which technical, biological and medical expertise co-fertilize on another with the ultimate aim of restoring, maintaining or improving tissues and/or organs. This purpose links TE closely to research concerning reconstructive plastic surgery. LÄS MER

  7. 25. Energy Efficient Protocols for Active RFID

    Författare :Björn Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wake-up radio; energy consumption; energy efficient; Active RFID; protocol; RFID; throughput; back-off; RFID-system; delay;

    Sammanfattning : Radio frequency identification (RFID) systems come in different flavours; passive, active, semi-passive, or semi-active. Those different types of RFID are supported by different, internationally accepted protocol standards as well as by several accepted proprietary protocols. LÄS MER
