  1. 1. Design, Fabrication and Optimization of Thermal Radiation Detectors Based on Thin Polymer Membranes

    Författare :Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Ylva Bäcklund; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detector; Polymer; Membrane; SU-8; Electronics; Elektronik;

    Sammanfattning : The number of applications in which infrared radiation sensors are used is increasing. In some applications, the cost of the sensor itself is an issue, and simple solutions are thus required. In this thesis, the investigations have related to the use of thin polymer membranes in thermal infrared sensors, such as bolometers and thermopiles. LÄS MER

  3. 2. Single-Proton Irradiation of Living Cells - Development of New Tools for Low-Dose Radiation Research

    Författare :Natalia Arteaga; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lithography; UVL; EBL; SeACell; human hepatoma cells HepG2 ; reactive oxygen species ROS ; bystander effect; SU-8; cell recognition; cell irradiation; Single-Ion Hit Facility; low-dose; Fysicumarkivet A:2010:Arteaga Marrero;

    Sammanfattning : A Single-Ion Hit Facility (SIHF) consists of a custom-build facility based in particle accelerators which offers irradiation controlling the number of delivered particles with a precise targeting localization. The irradiation spot can be confined down to the nanometre scale allowing the irradiation of subcellular compartments with a single particle. LÄS MER

  4. 3. Micro-scale Platforms for Investigations of Biological Structures

    Författare :Anna Kim; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microfabrication; non-ionic surfactants; single-cell viability; hydrodynamic flow confinement; cell-to-cell connections; SU-8; Teflon AF; cell protrusions; free-standing probes; millimeter-waves;

    Sammanfattning : This thesis describes the development of innovative micro-scale platforms as a means to address the current challenges within the field of cell biology, and to provide an interface between miniaturized analytical technology and experimental systems for the life sciences. The work includes an analytical platform for rapid assessment of the viability of adherent single cells; a surface patterning strategy for investigations of cell-to-cell communication via protrusions; a versatile microfluidic probe in SU-8 hard-polymer, and a microfabricated millimeter-wave measurement system for the identification and characterization of niosome (non-ionic surfactant vesicle) constituents, which is operated in a label-free, non-invasive manner.

  5. 4. Some Aspects of Advanced Technologies and Signal Integrity Issues in High Frequency PCBs, with Emphasis on Planar Transmission Lines and RF/Microwave Filters

    Författare :Felix D. Mbairi; Sture Petersson; Shaofang Gong; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal integrity; crosstalk; guard trace; PCB; transmission line loss; high frequency measurement; dielectric; SU-8; electromagnetic bandgap; microwave filter; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : The main focus of this thesis is placed on high frequency PCB signal Integrity Is-sues and RF/Microwave filters using EBG structures. From the signal Integrity aspect, two topics were mainly discussed. LÄS MER

  7. 5. Fabrication of cantilever chip with complementary micro channel system in SU-8 for biochemical detection

    Författare :Maria Tenje; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents the works on fabrication and measurements done with micro cantilevers and a micro channel system, fabricated in the photo-resist SU-8. SU-8 is a polymer patterned by UV lithography which offers a cheap and fast processing and is an interesting alternative to standard Si techniques. LÄS MER
