  • Preparation of magnetic composite based on zinc oxide nanoparticles and
           chitosan as a photocatalyst for removal of reactive blue 198

    • Authors: Van Cuong Nguyen; Ngoc Lam Giang Nguyen Quoc Hue Pho
      First page: 035001
      Abstract: In this study a novel magnetic composite used as a photocatalyst with combination of zinc oxide nanoparticles and chitosan (ZnO/Fe 3 O 4 /CS) was synthesized by a simple co-precipitation method. The role of the prepared magnetic nanocomposite is to improve the removal efficiency of textile dye due to the photocatalytic activity of zinc oxide nanoparticles and reusable capacity of Fe 3 O 4 magnetic nanoparticles. Constituents and structure properties of ZnO/Fe 3 O 4 /CS were investigated by scanning electron microscopy (SEM), x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). Magnetic property of the prepared composite was determined by vibrating sample magnetometer (VSM). The results demonstrated that ZnO/Fe 3 O 4 /CS nanocomposite dramatically improved the removal efficiency of reactive blue 198 dye (RB198) with high photocatalytic activity and easy...

  • Quantum field theory of interacting plasmon?photon?phonon system

    • Authors: Van Hieu Nguyen; Bich Ha Nguyen
      First page: 035003
      Abstract: This work is devoted to the construction of the quantum field theory of the interacting system of plasmons, photons and phonons on the basis of general fundamental principles of electrodynamics and quantum field theory of many-body systems. Since a plasmon is a quasiparticle appearing as a resonance in the collective oscillation of the interacting electron gas in solids, the starting point is the total action functional of the interacting system comprising electron gas, electromagnetic field and phonon fields. By means of the powerful functional integral technique, this original total action is transformed into that of the system of the quantum fields describing plasmons, transverse photons, acoustic as well as optic longitudinal and transverse phonons. The collective oscillations of the electron gas is characterized by a real scalar field ? ( x ) called the collective oscillation field. This field is split into the static background field ? 0 ( x ...

  • Poly(ethylene glycol) grafted chitosan as new copolymer material for oral
           delivery of insulin

    • Authors: Thanh Ha Ho; Thi Nu Thanh Le, Tuan Anh Nguyen Mau Chien Dang
      First page: 035004
      Abstract: A new scheme of grafting poly (ethylene glycol) onto chitosan was proposed in this study to give new material for delivery of insulin over oral pathway. First, methoxy poly(ethylene glycol) amine (mPEGa MW 2000) were grafted onto chitosan (CS) through multiples steps to synthesize the grafting copolymer PEG- g -CS. After each synthesis step, chitosan and its derivatives were characterized by FTIR, 1 H NMR Then, insulin loaded PEG- g -CS nanoparticles were prepared by cross-linking of CS with sodium tripolyphosphate (TPP). Same insulin loaded nanoparticles using unmodified chitosan were also prepared in order to compare with the modified ones. Results showed better protecting capacity of the synthesized copolymer over original CS. CS nanoparticles (10 nm of size) were gel like and high sensible to temperature as well as acidic environment while PEG- g -CS nanoparticles (200 nm of size) were rigid and more thermo and pH stable.

  • A 2D analytical cylindrical gate tunnel FET (CG-TFET) model: impact of
           shortest tunneling distance

    • Authors: S Dash; G P Mishra
      First page: 035005
      Abstract: A 2D analytical tunnel field-effect transistor (FET) potential model with cylindrical gate (CG-TFET) based on the solution of Laplace?s equation is proposed. The band-to-band tunneling (BTBT) current is derived by the help of lateral electric field and the shortest tunneling distance. However, the analysis is extended to obtain the subthreshold swing (SS) and transfer characteristics of the device. The dependency of drain current, SS and transconductance on gate voltage and shortest tunneling distance is discussed. Also, the effect of scaling the gate oxide thickness and the cylindrical body diameter on the electrical parameters of the device is analyzed.

  • Hydrothermal synthesis and NH 3 gas sensing property of WO 3 nanorods at
           low temperature

    • Authors: Dac Dien Nguyen; Duc Vuong Dang Duc Chien Nguyen
      First page: 035006
      Abstract: One-dimensional self-assembled single-crystalline hexagonal tungsten trioxide (WO 3 ) nanostructures were synthesized by wet chemical-assisted hydrothermal processing at 120 ?C for 24 h using sodium tungstate and hydrochloric acid. Urchin-like hierarchical nanorods (petal size: ?16 nm diameter and 110 nm length) were obtained. The samples were characterized by field emission scanning electron microscopy, transmission electron microscopy, energy dispersive x-ray spectroscopy and x-ray diffraction. Sensors based on WO 3 nanorods were fabricated by coating them on SiO 2 /Si substrate attached with Pt interdigitated electrodes. NH 3 gas-sensing properties of WO 3 nanorods were measured at different temperatures ranging from 50 ?C to 350 ?C and the response was evaluated as a function of ammonia gas concentration. The gas-sensing results reveal that WO 3 nanorods sensor exhibits high sensitivity and selectivity to NH 3

  • Optimization of copper electroplating process applied for microfabrication
           on flexible polyethylene terephthalate substrate

    • Authors: Nguyen Ngan Le; Thi Cam Hue Phan, Anh Duy Le, Thi My Dung Dang Mau Chien Dang
      First page: 035007
      Abstract: Electroplating is an important step in microfabrication in order to increase thickness of undersized parts up to a few micrometers with a low-cost, fast method that is easy to carry out, especially for metals such as copper, nickel, and silver. This important step promotes the development of the fabrication technology of electronic devices on a flexible substrate, also known as flexible electronic devices. Nevertheless, this technology has some disadvantages such as low surface uniformity and high resistivity. In this paper, parameters of copper electroplating were studied, such as the ratio of copper (II) sulfate (CuSO 4 ) concentration to sulfuric acid (H 2 SO 4 ) concentration and electroplating current density, in order to obtain low resistivity and high surface uniformity of the copper layer. Samples were characterized by scanning electron microscopy (SEM), four-point probe, and surface profiler. The results showed that the sample resistivity could...

           photoanode based dye-sensitized solar cell

    • Authors: Muthusamy Anand; Santhanakrishnan Suresh
      First page: 035008
      Abstract: The exploitation of marine seaweed ( Sargassum wightii ) extract as a low-cost sensitizer for a ZnO photoanode based solar cell is reported. The UV?vis absorbance spectrum of the Sargassum wightii ( S. wightii ) extract has exhibited three absorption peaks at 412.5, 610 and 659.5 nm in visible region of the solar spectrum. The pigment analysis has confirmed the presence of photosynthetic pigments such as chlorophylls, carotenoids and fucoxanthin. The photovoltaic performance of the S. wightii extract as a sensitizer in ZnO photoanode based solar cell is examined under simulated solar light irradiation. The solar cell sensitized with the S. wightii extract has delivered a short-circuit photocurrent density ( J sc ) of 203 ? A cm ?2 , open-circuit photo-voltage ( V oc ) of 0.33 V, maximum peak power ( P max ) of 31.02 ? W, fill factor of 0.46 and an overall solar to electrical energy co...

    • Authors: S H Chaki; Tasmira J Malek, M D Chaudhary, J P Tailor M P Deshpande
      First page: 035009
      Abstract: The authors report the synthesis of Fe 3 O 4 nanoparticles by wet chemical reduction technique at ambient temperature and its characterization. Ferric chloride hexa-hydrate (FeCl 3???6H 2 O) and sodium boro-hydrate (NaBH 4 ) were used for synthesis of Fe 3 O 4 nanoparticles at ambient temperature. The elemental composition of the synthesized Fe 3 O 4 nanoparticles was determined by energy dispersive analysis of x-rays technique. The x-ray diffraction (XRD) technique was used for structural characterization of the nanoparticles. The crystallite size of the nanoparticles was determined using XRD data employing Scherrer?s formula and Hall?Williamson?s plot. Surface morphology of as-synthesized Fe 3 O 4 nanoparticles was studied by scanning electron microscopy. High resolution transmission electron microscopy analysis of the as-synthesized Fe 3 O 4 nanoparticles ...
