  • flexible and robust amino functionalized Glass Fiber Filter paper polyaniline composite films as free standing tensile tolerant electrodes for high performance supercapacitors
    Electrochimica Acta, 2017
    Co-Authors: Hongxing Wang, Pengcheng Du
    Abstract:

    Flexible and robust amino-functionalized Glass Fiber Filter paper/polyaniline (A-GFFP/PANI) composite films were fabricated as free-standing tensile-tolerant electrodes for high performance supercapacitors, by facile in-situ chemical oxidative polymerization of aniline on the surface of Glass Fiber Filter paper (GFFP) in sulfuric acid solution, after surface modification. The results showed that the surface modification of GFFP with (3-aminopropyl)triethoxysilane played a role as bridge for connecting the polyaniline and Glass Fiber, resulting to unique polyaniline (PANI) coating and subsequently better electrochemical properties. The specific capacitance and electrical conductivity of the A-GFFP/PANI-1 electrode, which was fabricated via the conventional chemical oxidative polymerization of aniline With concentration of 0.18 mol/L, were 391.3 F/g and 2.78 S/cm, while the A-GFFP/PANI-2 electrode, prepared via rapid-mixing chemical oxidative polymerization under the same preparation condition, possessed the specific capacitance and electrical conductivity of 490.6 F/g and 1.83 S/cm. The capacitance retention of the A-GFFP/PANI-2 electrode (106. 8%) was also better than that of the A-GFFP/PANI-1 electrode (98.0%) after 2000 CV cycles at a scan rate of 100 mV/s, also owing to the bridging function of the functional silane. The A-GFFP/PANI-2 electrode retained 72.6% of its initial specific capacitance under the stress of 0.70 MPa for 1 h, indicating its good tolerance to tensile. (C) 2017 Elsevier Ltd.

  • The Fate of Mengovirus on FiberGlass Filter of Air Handling Units
    Food and Environmental Virology, 2017
    Co-Authors: Victor Bandaly, Aurélie Joubert, Pierre Le Cann, Yves Andres
    Abstract:

    One of the most important topics that occupy public health problems is the air quality. That is the reason why mechanical ventilation and air handling units (AHU) were imposed by the different governments in the collective or individual buildings. Many buildings create an artificial climate using heating, ventilation, and air-conditioning systems. Among the existing aerosols in the indoor air, we can distinguish the bioaerosol with biological nature such as bacteria, viruses, and fungi. Respiratory viral infections are a major public health issue because they are usually highly infective. We spend about 90% of our time in closed environments such as homes, workplaces, or transport. Some studies have shown that AHU contribute to the spread and transport of viral particles within buildings. The aim of this work is to study the characterization of viral bioaerosols in indoor environments and to understand the fate of mengovirus eukaryote RNA virus on Glass Fiber Filter F7 used in AHU. In this study, a set-up close to reality of AHU system was used. The mengovirus aerosolized was characterized and measured with the electrical low pressure impact and the scanner mobility particle size and detected with RT-qPCR. The results about quantification and the level of infectivity of mengovirus on the Filter and in the biosampler showed that mengovirus can pass through the Filter and remain infectious upstream and downstream the system. Regarding the virus infectivity on the Filter under a constant air flow, mengovirus was remained infectious during 10 h after aerosolization.

  • Glass Fiber coalescing Filter media augmented with polymeric submicron Fibers and modified with angled drainage channels
    Separation and Purification Technology, 2013
    Co-Authors: Prashant S Kulkarni, Shagufta U Patel, George G. Chase
    Abstract:

    Abstract Glass Fiber Filter media are widely used in separation of droplets from liquid aerosols. In prior works two possible enhancements to the performance of the Glass Fiber media were studied: (1) the capture efficiencies were increased by augmenting the Glass Fibers with sub-micron sized electrospun polymer Fibers, and (2) the pressure drop was decreased by modifying the Filter media with insertion of 45° drainage channels. In this paper we report the simultaneous application of these two enhancements on the performance of the Filter media. Filters were fabricated by inserting low surface energy woven polymer Fiber drainage channels at various angles within non-woven Glass Fiber Filter media augmented with Nylon sub-micron Fibers. The effects of the presence and geometry of the drainage channels on the Filter performance were evaluated experimentally. The sub-micron Fibers gave the Filter high coalescence and separation efficiencies while the drainage channels reduced the Filter pressure drop. The micro Glass Fiber media augmented with 100 nm Nylon Fibers and modified with Polypropylene Fiber drainage channels at 45° downward angles had the overall best performance.

  • Separation of Liquid Drops from Air by Glass Fiber Filters Augmented with Polystyrene NanoFibers
    Journal of Dispersion Science and Technology, 2006
    Co-Authors: C. Shin, George G. Chase
    Abstract:

    Expanded polystyrene (EPS) was recycled into a useful nanoFiber for which large lengths are produced per mass of polymer. These nanoFibers are mixed with micro Glass Fibers to modify the Glass Fiber Filter media. The Filter media are tested in the separation of oil droplets from air. The filtration experiments show that the addition of small amounts of polystyrene nanoFibers significantly improves the removal of particles and the quality factor of the Filter, but also increases the pressure drop of the Filters. An optimum in the performance occurs with the addition of 7% or less by mass of 500 nanometer average diameter polystyrene nanoFibers to Glass microFibers (average Fiber diameter of about 5 microns). This optimum balances the desired improvement in coalescence efficiency and the undesired increase in pressure drop.

  • Recycled expanded polystyrene nanoFibers applied in Filter media
    Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2005
    Co-Authors: C. Shin, George G. Chase, Darrell H. Reneker
    Abstract:

    Abstract In this work polystyrene (PS) nanoFibers are electrospun from recycled expanded polystyrene (EPS). These Fibers are mixed with micro Glass Fibers to modify the Glass Fiber Filter media. The Filter media are tested in the separation of water droplets from an emulsion of water droplets in oil. Water-in-oil emulsion separations are important to the petrochemical industries for product quality, safety, ecologic and economic reasons. The experimental results in this work show that polystyrene nanoFibers with diameters of around 600 nm were produced by the electrospinning method. The addition of the nanoFibers to conventional micron sized fibrous Filter media improves the separation efficiency of the Filter media from 68 to 88%.
