  • Support to Aviation Control Service (SACS): an online service for near-real-time satellite monitoring of volcanic plumes

    Volcanic eruptions emit plumes of ash and gases into the atmosphere, potentially at very high altitudes. Ash-rich plumes are hazardous for airplanes as ash is very abrasive and easily melts inside their engines. With more than 50 active volcanoes per year and the ever-increasing number of commercial flights, the safety of airplanes is a real concern. Satellite measurements are ideal for ...

  • Optoelectronic properties of various HgTe nanoparticle-based structures in the visible and infrared wavelength range

    Structural, optical, and electrical properties of various HgTe nanoparticle-based structures including a hybrid HgTe system with organic capping material and a HgTe/CdTe core-shell structure are characterised in this paper by X-ray diffraction, high-resolution transmission electron microscope, photoluminescence (PL), absorption, and current-voltage and photocurrent measurements. Absorption and PL ...

  • Application of dynamic threshold in sea and lake ice mapping and monitoring

    Ice detection and monitoring algorithms using visible and infrared images are generally founded on thresholds-based approaches. Classification of features over ice covered sea requires a series of reliable thresholds. The change in surface conditions throughout the season affects these thresholds and makes their adjustment necessary. This study proposes an operational method based on a set of ...

  • Prediction of intact nectarine quality using a Vis/NIR portable spectrometer

    A commercial visible-near infrared spectrometer was tested for intact nectarine quality prediction using partial least squares calibrations. Soluble solids content, firmness, fruit weight and colour index were analysed in each fruit. External validation carried out indicated good predictive performance, particularly for soluble solids content and fruit firmness. These parameters are of key ...

  • Laser-based 2D and 3D nanomanufacturing for plasmonic applications

    Growing interest in the field of surface plasmon polaritons (SPPs) comes from a rapid advance of nanostructuring technologies. The application of two-photon polymerisation technique for the fabrication of dielectric and metallic SPP-structures, which can be used for localisation, guiding, and manipulation of SPP waves on a subwavelength scale are studied. This technology is based on non-linear ...

  • Intermediate Reynolds/Peclet number, flat plate boundary layer flows over catalytic surfaces for micro-combustion applications

    The reactive, flat plate boundary layer flow of close-tostoichiometric, methaneair mixtures over small size Pt plates is studied experimentally for intermediate Reynolds and Peclet numbers which pertain to micro-combustion applications. The surface temperature was measured with infrared thermography and correlated to reactant concentration profiles acquired with line-Raman imaging. Three phases ...

  • Study of the effect of an acid treatment of a natural Moroccan bentonite on its physicochemical and adsorption properties

    In this study, a natural bentonite taken from a deposit in the Northeast of Morocco has been purified (PB) and treated with various HCl molarities (xHPB) in order to obtain an HCl/Bentonite weight ratio equal to 0.2, 0.4 and 0.6. The obtained physicochemical characterization results indicated that the PB sample is composed mainly of the montmorillonite phase. The impact of acid treatment was ...

  • Demonstration of a 33% efficient Cassegrainian Solar Module

    Abstract The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is reported measured outdoors for a solar concentrator PV module using InGaP/GaAs dual ...
