  1. 1. Silicon neural interfaces -Design and biomedical aspects-

    University dissertation from Lars Wallman, Dept. of electrical measurements, box 118, 221 00 LUND

    Author : Lars Wallman; Lund University.; Lunds universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; pn-etch stop; biocompatibility; neural recordings; porous silicon; silicon; neural interface; sieve electrode; General biomedical sciences; Biomedicinska vetenskaper allmänt ;

    Abstract : This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon.

  2. 2. Cold lap formation in Gas Metal Arc Welding of steel An experimental study of micro-lack of fusion defects

    University dissertation from Trollhättan : University West

    Author : Peigang Li; Lars-Erik Svensson; Norbert Enzinger; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tandem GMAW; old laps; lack of fusion; Spatter; Overlap; Overflow; Manganese; Silicon; Oxides; Temperature; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).

  4. 4. Electronic Structure of Transition Metal Complexes in Silicon

    University dissertation from Solid State Physics, Lund University

    Author : Per Tidlund; Lund University.; Lunds universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; uniaxial stress; FTIR; Zeeman spectroscopy; deep levels; phonon-assisted Fano resonances; Physics; Fysik; Au; Fysicumarkivet A:1998:Tidlund; PtLi; AuLi; Pt; Transition Metals; Silicon;

    Abstract : This thesis consists of experimental studies of the electronic of electronic structure of the transition metals Au and Pt, and the transition metal complexes, FeIn, PtLi, and AuLi in silicon. Fourier transform infrared spectroscopy, photoconductivity, uniaxial stress- and Zeeman spectroscopy are employed. READ MORE

  5. 5. Polymer Microoptics in Silicon Micromachining

    University dissertation from Solid State Physics, Lund University

    Author : Karin Hedsten; []
