  1. 1. Nanoplasmonic Alloy Hydrogen Sensors

    Author : Ferry Nugroho; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; indirect nanoplasmonic sensing; plasmonic sensors; hydrogen sensors; polymers; fiber optics; nanofabrication; localized surface plasmon resonance; alloy nanoparticles; carbon capture and storage; sensors; palladium;

    Abstract : The hydrogen economy proposes hydrogen gas as the main energy carrier thanks to its high energy density and the possibility to produce it in a sustainable way without CO2 emission. However, the wide flammability range of hydrogen-air mixtures dictates that hydrogen sensors will be a mandatory accessory to any appliance or vehicle fueled by hydrogen. READ MORE

    Abstract : A successful long-term high resolution imaging experiment in marine sediments was performed (17 days within the sample; Paper I). The time correlated calibration procedure was evolved to include parametric sigmoidal and logarithmic functions to provide three of the best performing (optical) pH sensors available up to date (Papers II, III and IV), precision of these sensors were in the 0.
