  1. 1. Spatially resolved gas sensing

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Mikael Löfdahl; Werner Moritz; [2001]

    Sammanfattning : By using a Scanning Light Pulse Technique (SLPT) the gas response of catalytic Metal-Insulator semiconductor (MIS) devices can be spatially resolved.The application of SLPT to gas sensitive MIS devices can be divided into two areas. LÄS MER

  2. 2. Used but not Sensed - The Paradox of D-xylose Metabolism in Saccharomyces cerevisiae

    Detta är en avhandling från Department of Chemistry, Lund University

    Författare :Karen Ofuji Osiro; [2019-06-14]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; saccharomyces cerevisiae; sugar sensing signalling; D-Xylose; XR XDH; GFP biosensor; cAMP PKA; Snf3p Rgt2p; SNF1 Mig1p; flow cytometry;

    Sammanfattning : The realization that the extraction and combustion of fossil fuels is having serious effects on the environment and the climate, together with the ever-growing need for fuels, has led to the development of the concept of the biorefinery. Biorefineries are refineries in which fossil resources, such as oil, are replaced by renewable biomaterials to produce biofuels and biochemicals. LÄS MER

  3. 3. Drowning-out crystallisation of benzoic acid Influence of processing conditions and solvent composition on crystal size and shape

    Detta är en avhandling från Stockholm : Kemiteknik

    Författare :Xiomara Holmbäck; [2002]
    Nyckelord :solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Sammanfattning : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. LÄS MER

  4. 4. Microfabricated Gas Sensors Based on Hydrothermally Grown 1-D ZnO Nanostructures

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mingzhi Jiao; Hugo Nguyen; Klas Hjort; Anita Lloyd Spetz; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas sensor; zinc oxide; on-chip; hydrothermal growth; nanorods; nanowires; annealing; palladium oxide; photoluminescence; alloy; sensitivity; selectivity; stability;

    Sammanfattning : In this thesis, gas sensors based on on-chip hydrothermally grown 1-D zinc oxide (ZnO) nanostructures are presented, to improve the sensitivity, selectivity, and stability of the gas sensors.Metal-oxide-semiconductor (MOS) gas sensors are well-established tools for the monitoring of air quality indoors and outdoors.
