    Sammanfattning : Today’s MEMS technology allows manufacturing of miniaturized, low power sensors that sometimes exceeds the performance of conventional sensors. The pressure sensor market today is dominated by MEMS pressure sensors.In this thesis two different pressure sensor techniques are studied. LÄS MER

  3. 2. Fabrication and Characterization of Composite TiO2/Carbon Nanofilms with Enhanced Photocatalytic Activity

    Författare :Raja Sellappan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TiO2; carbon; photoluminescence; photodegradation; recombination.; Photocatalysis;

    Sammanfattning : The work presented in this thesis is dedicated to fabrication and characterization of an efficient thin film photocatalyst for environmental cleaning and solar fuel applications. Because of its simplicity and reproducible fabrication, the chosen combination of nanometer thin titania and carbon films serves also as a model system for a wider class of photoactive materials.

    Författare :Marina Craig; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; triggered release; multilayer; controlled release; Layer-by-layer; nanofilm; infection; enzymatic degradation;

    Sammanfattning : The number of diabetics, obese individuals and other patients carrying other lifestyle diseasesis increasing worldwide. At the same time the population is ageing. These patients all sufferfrom poor blood circulation, which often gives rise to non-healing, or chronic, wounds. Thus,the number of chronic wounds is also increasing at a fast pace. LÄS MER
