  2. 1. Charge Separation on Localized Surface Plasmon and Hot Carrier Transfer to Semiconductors

    Author : Yocefu Hattori; Jacinto Sá; Stephan Link; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasmonics; hot carrier; metal nanoparticles; semiconductors; ultrafast transient absorption spectroscopy; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : The relatively recent discovery that plasmonic nanoparticles generate energetic electron-hole pairs known as hot carriers has been the source of interest from many scientific groups. The capability to extract these short-lived hot carriers from metal nanoparticles (NPs) might potentially lead to applications in solar cells, photodetection, and photocatalysis. READ MORE

  4. 2. Considering a Baby? Responsible Screening for the Future : Ethical and social implications for implementation and use of preconception expanded carrier screening in Sweden

    Author : Amal Matar; Anna T Höglund; Mats G. Hansson; Lars Sandman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preconception expanded carrier screening; reproductive autonomy; solidarity; popula-tion screening; genomics; ELSI;

    Abstract : Preconception expanded carrier screening is a novel technology that involves the offer of a screening test for many recessive diseases (via an expanded screening panel) to prospective parents, with no priori risk. Test positive couples have a number of reproductive choices; prenatal diagnosis and aborting affected fetus, IVF and preimplantation genetic diagnosis, sperm or ovum donation or simply accept the risk.

  5. 3. Towards energy efficient protocols for active RFID

    Author : Björn Nilsson; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RFID; active RFID; protocol; back-off; carrier sense; energy efficient; wireless networks; active tag; energy consumption; Computer engineering; Datorteknik;

    Abstract : The absence of a global standard is a bottleneck when using Radio Frequency Identification (RFID) technology. This thesis explores data communication protocols for Active-RFID regarding their energy efficiency and how they can be suited to fit a large variety of applications. READ MORE

  6. 4. 4H-SiC epitaxy investigating carrier lifetime and substrate off-axis dependence

    Author : Louise Lilja; Peder Bergman; Jawad ul-Hassan; Ulrike Grossner; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Silicon carbide (SiC) is a wide bandgap semiconductor with unique material properties making it useful for various device applications using high power, high frequency and high temperature. Compared to Si-based electronics, SiC based electronics have an improved energy efficiency. READ MORE

  7. 5. In vitro and in vivo studies of tissue engineering in reconstructive plastic surgery

    Author : Fredrik R.M. Huss; Gunnar Kratz; Elof Eriksson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue engineering; plastic surgery; guided tissue regeneration; Plastic surgery; Plastikkirurgi; Plastikkirurgi;

    Abstract : To correct, improve, and maintain tissues, and their functions, are common denominators in tissue engineering and reconstructive plastic surgery. This can be achieved by using autolo-gous tissues as in flaps or transplants. However, often autologous tissue is not useable. READ MORE
