  • Deicing of wind turbine blade by high frequency Dielectric Heating fabricating blade as a capacitor
    2017 International Conference on Circuit Power and Computing Technologies (ICCPCT), 2017
    Co-Authors: Datta. S. Chavan, Shital Gaikwad, Vivek Saahil, Divya Parashar, Anupama Singh, Jaywant Sankpal, Parashuram Balwant Karandikar
    Abstract:

    In this paper wind turbine blade is formed as a capacitor. The ice accumulated on the wind turbine blade is removed by Dielectric Heating. High frequency supply is used for Heating. The metallic plates are embedded in the wind turbine blades when the blade is being manufactured. The metallic plates are separated by the insulation medium. The plates are completely covered by the insulating material. This construction also enhances the strength of the wind turbine blade due to reinforcement by the metallic plate. The supply is given to the blade capacitor when the ice is accumulated. The ice is sensed by ice sensor. The supply to the capacitor may be given by the battery bank. The wind turbine is stopped when the ice is being removed by Dielectric Heating. The area below the wind turbine is vacated. The human beings and animals are not allowed to go near the turbine as the ice may fall below and the person or animal may be injured due to ice.

  • applications of microwave Dielectric Heating in environment related heterogeneous gas phase catalytic systems
    Inorganica Chimica Acta, 2006
    Co-Authors: Xunli Zhang, David O Hayward
    Abstract:

    The application of microwave Dielectric Heating in a range of environment-related heterogeneous catalytic reaction systems has been reviewed. The reactions investigated include the decomposition of hydrogen sulfide, the reduction of sulfur dioxide with methane, the reformation of methane by carbon dioxide, the hydrodesulfurization of thiophene, and the oxidative coupling of methane. The interaction of microwave irradiation with heterogeneous catalytic systems and its consequence for the microwave Heating behaviour of catalysts have been examined. The effect/mechanism of microwave Dielectric Heating on heterogeneous catalytic reaction systems has also been discussed.

  • effects of microwave Dielectric Heating on heterogeneous catalysis
    Catalysis Letters, 2003
    Co-Authors: Xunli Zhang, David O Hayward, Michael D P Mingos
    Abstract:

    The effect of microwave Dielectric Heating on both endothermic and exothermic reactions was investigated. Apparent equilibrium shifts for both reactions were observed which were attributed to the formation of spatial hot spots in the catalyst bed. The possible location of remarkable temperature gradients was examined experimentally and theoretically.

  • apparent equilibrium shifts and hot spot formation for catalytic reactions induced by microwave Dielectric Heating
    Chemical Communications, 1999
    Co-Authors: Xunli Zhang, David O Hayward, Michael D P Mingos
    Abstract:

    Microwave Dielectric Heating of the gas phase decomposition of H2S catalysed by metal sulfides on a γ-Al2O3 support results in significant apparent shifts in the equilibrium constant, which have been attributed to the development of hot-spots in the catalytic beds; X-ray diffraction and electron microscopy measurements have indicated the formation of hot-spots with dimensions of 90–1000 µm and which involve not only the active phase, but also the support.

  • Fabrication and applications of ultraflexible nanostructures using Dielectric Heating-assisted nanoimprint on PVC films
    Current Applied Physics, 2018
    Co-Authors: Tsung Yeh Wu, Po Cheng Tsai, Shu Cheng Lo, Yi Ru Li, Kuang Li Lee, Sen-yeu Yang, Pei Kuen Wei
    Abstract:

    We developed Dielectric Heating-assisted nanoimprint method for rapid fabrication of ultraflexible nanostructures. Using spin-coating polyvinyl-chloride (PVC) film on the glass slide, the Dielectric Heating on PVC film helped the pattern transfer from the mold to PVC film in few seconds. Various kinds of nanostructures were successfully made on PVC films with about 20-μm thickness. We demonstrated the applications of ultraflexible metallic nanostructures for bending measurement using surface plasmon resonance (SPR) and surface enhanced Raman scattering (SERS) on the curved surfaces. For measuring bending angles using SPR on capped nanowire arrays, the minimum detection angle was 2.4 × 10 −3 degree under 0.02 nm wavelength resolution. For SERS measurement, the nanorod arrays on a curved substrate can increase SERS signals for two times as compared to planar SERS substrate.

  • low cost and rapid fabrication of metallic nanostructures for sensitive biosensors using hot embossing and Dielectric Heating nanoimprint methods
    Sensors, 2017
    Co-Authors: Tsung Yeh Wu, Sen-yeu Yang
    Abstract:

    We propose two approaches—hot-embossing and Dielectric-Heating nanoimprinting methods—for low-cost and rapid fabrication of periodic nanostructures. Each nanofabrication process for the imprinted plastic nanostructures is completed within several seconds without the use of release agents and epoxy. Low-cost, large-area, and highly sensitive aluminum nanostructures on A4 size plastic films are fabricated by evaporating aluminum film on hot-embossing nanostructures. The narrowest bandwidth of the Fano resonance is only 2.7 nm in the visible light region. The periodic aluminum nanostructure achieves a figure of merit of 150, and an intensity sensitivity of 29,345%/RIU (refractive index unit). The rapid fabrication is also achieved by using radio-frequency (RF) sensitive plastic films and a commercial RF welding machine. The Dielectric-Heating, using RF power, takes advantage of the rapid Heating/cooling process and lower electric power consumption. The fabricated capped aluminum nanoslit array has a 5 nm Fano linewidth and 490.46 nm/RIU wavelength sensitivity. The biosensing capabilities of the metallic nanostructures are further verified by measuring antigen–antibody interactions using bovine serum albumin (BSA) and anti-BSA. These rapid and high-throughput fabrication methods can benefit low-cost, highly sensitive biosensors and other sensing applications.

  • methane catalytic combustion over la ce mn o perovskite prepared using Dielectric Heating
    Catalysis Communications, 2009
    Co-Authors: A Kaddouri, P Gelin, N Dupont
    Abstract:

    Abstract In the present work we report on the influence of the preparation method on the physicochemical and catalytic properties of La–Ce–Mn–O- catalysts used for methane combustion. Samples were prepared hydrothermally using both conventional (CH) and Dielectric Heating (MH). Catalysts were characterized by N 2 adsorption–desorption, X-ray powder diffraction (XRD), temperature-programmed reduction by H 2 (H 2 -TPR) and temperature-programmed desorption-mass spectrometry (TPD-MS). An analysis of XRD and TPR data leads us to conclude that microwave irradiation leads to formation of La 1− x Ce x MnO 3  +  e CeO 2 ( x  +  e  = 0.2), whereas conventional Heating leads to CH-LaMnO 3  + CeO 2 systems. Catalytic combustion of methane without and with 100 ppmv H 2 S was carried out using a GHSV of 8000 h −1 and oxygen-to-methane ratio of 4. Microwave prepared sample was found to be the best both in terms of sulphur tolerance and percent CH 4 conversion. The superior catalytic performance of the catalyst prepared using Dielectric Heating was attributed to a well dispersed cerium oxide species strongly interacting with the LaMnO 3 host structure.
