  1. 1. Additives Increasing the Bone-Forming Potential around Calcium Phosphate Cements : Statin, Strontium and Silicon

    Författare :Maryam Montazerolghaem; Marjam Karlsson Ott; Håkan Engqvist; Pedro Granja; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Phosphate Cements; Osteoblast; Osteoclast; Monetite; Zebrafish; Simvastatin; Strontium; Silicon; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : More than one million people worldwide receive some kind of bone graft each year. Grafts are often needed following bone tumour removal or traumatic fractures to fill voids in the bone and to aid in the healing process. LÄS MER

  2. 2. Fabrication and characterization of single luminescing quantum dots from 1D silicon nanostructures

    Författare :Benjamin Bruhn; Jan Linnros; Luca Dal Negro; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; silicon; quantum dot; nanocrystal; nanowire; nanostructure; photoluminescence;

    Sammanfattning : Silicon as a mono-crystalline bulk semiconductor is today the predominant material in many integrated electronic and photovoltaic applications. This has not been the case in lighting technology, since due to its indirect bandgap nature bulk silicon is an inherently poor light emitter. LÄS MER

  3. 3. Ultralow-loss silicon nitride waveguides for nonlinear optics

    Författare :Zhichao Ye; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parametric amplifier; DKS microcombs; ultralow loss; integrated waveguides; Kerr nonlinear optics; silicon nitride;

    Sammanfattning : The field of nonlinear optics relies on the interaction between high-intensity optical waves and nonlinear media. An integrated waveguide with large refractive index contrast allows to highly confine optical waves in a sub-μm^2 area, thus enhancing the optical intensity. LÄS MER

  4. 4. Silicon Nanowire Based Electronic Devices for Sensing Applications

    Författare :Qitao Hu; Zhen Zhang; Shi-Li Zhang; Si Chen; Jeehwan Kim; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; silicon nanowire; field-effect transistor; nanoelectromechanical resonator; CMOS-compatible; multiplexed detection; single charge detection; quantum sensing; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : Silicon nanowire (SiNW) based electronic devices fabricated with a complementary metal-oxide-semiconductor (CMOS) compatible process have wide-range and promising applications in sensing area. These SiNW sensors own high sensitivity, low-cost mass production possibility, and high integration density. LÄS MER

  5. 5. Porous Silicon -an enzyme coupling matrix for micromachined reactors

    Författare :Johan Drott; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; glucose; biosensor; immobilised enzyme; porous silicon; microreactor; Mät- och instrumenteringsteknik;

    Sammanfattning : The development of a miniaturised silicon wafer integrated enzyme reactor is described. The reactor was micromachined by anisotropic wet etching of (110) silicon. The enzyme glucose oxidase (GOx) was coupled to the reactor surface with standard methods of immobilising enzyme to silica. LÄS MER
