  1. 16. Characterization of an On-chip Photonic Waveguide gas Sensor

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Olle Andersson; [2017]
    Keywords : ;

    Abstract : Gas sensing in medical applications requiresmall, precise and sensitive sensors. This projecthas developed a laboratory setup for characterisationof a waveguide-based gas sensor for carbon dioxide andmethane working in the mid-IR range of 2 - 10 μm. Thissetup utilizes an IR-camera to image the waveguideswhen a mid-IR laser is coupled into them. READ MORE

  3. 17. Near-Infrared Spectral Measurements and Multivariate Analysis for Predicting Glass Contamination of Boiler Fuel

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Olivia Winn; Kiran Thekkemadathil Sivaram; [2017]
    Keywords : NIRS; glass detection; food waste; biomass; PLS; SNV; Savitzky-Golay;

    Abstract : This degree project investigates how glass contamination in refuse-derived fuel for a fluidised bed boiler can be detected using near-infrared spectroscopy. It is motivated by the potential to reduce greenhouse gas emissions by replacing fossil fuels with refuse-derived fuel. READ MORE

  4. 18. Optical Remote Measurements of Particles in Emission Gas Plumes

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Weihua Wang; [2017]
    Keywords : Absorption spectroscopy; Aerosol; DOAS; SOF; Temporal-spatial data analysis; 吸收光谱学; 气溶胶; 差分吸收光谱技术; 掩光通量测量法; 时空域数据分析;

    Abstract : This project aims to use temporal and spatial data analysis to express the measured air pollutant concentrations as well as their relation with the aerosol traces, indicated by the intensity ratio (IR). The surveying were performed during a field campaign of several days of mobile optical remote sensing measurements in Tianjing city, China. READ MORE

  5. 19. The Functionalization of Epitaxial Graphene on SiC with Nanoparticles towards Biosensing Capabilities

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska fakulteten

    Author : Carl Strandqvist; [2015]
    Keywords : Graphene; Epitaxial; Silicon carbide; SiC; Nanoparticles; NPs; TiO2; Fe3O4; Functionalization; Gas sensing; CO; CH2O; C6H6; NH3; Carbon monoxide; Formaldehyde; Benzene; Ammonia; WHO; Hollow cathode; plasma sputtering; AFM; XPS; Raman spectroscopy; Surface characterization; Surface potential; Biosensor; Biosensing;

    Abstract : Graphene has been shown to be very powerful as a transducer in many biosensor applications due to its high sensitivity. This enables smaller surfaces and therefore less material consumption when producing sensors and concequently cheaper and more portable sensors compared to the commercially available sensors today.
