  • 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...

  • Verification of resistance to three mediated microbial strains and
           cancerous defense against MCF7 compared to HepG2 through microwave
           synthesized plant-mediated silver nanoparticle

    • Authors: W I Abdel-Fattah; M M Eid, M F Hanafy, M Hussein, Sh I Abd El-Moez, S M El-Hallouty E Mohamed
      First page: 035002
      Abstract: The antimicrobial and anticancer efficiencies of green synthesized silver nanoparticles (AgNPs) through biogenic extracts were assessed on three bacterial strains and two cancer cell lines. Bio-synthesized AgNPs were achieved through domestic microwave generator for obtaining extracts from Asian nuts and Egyptian blackberry fruits. Surface plasmon resonance (SPR) ?435 nm demonstrated AgNPs earlier formation by the fruit extract. Capping by triglycerides/almond and phenols/berry extracts were responsible for the reduction proved by FTIR. XRD calculated particle sizes were 18 and 42 nm while TEM sizes are 24.5 and 21.5 nm for AgNPs from almond nut and blackberry fruits extracts (Alm.N.Ext. and BB.F.Ext.), respectively. Ag 3d5/2 was recorded at 368.12 eV for both samples through XPS. The monodispersed AgNPs recorded 0.727 and 0.5 polydispersity indices (PdI) for almond/Ag and berry/Ag, respectively. Zeta potential ? ?31 and ?13.2 for the same sequence confirmed the higher stability ...

  • 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.

  • Performance evaluation of photovoltaic cells using functionalized carbon
           nanotube and polyaniline film

    • Authors: S Kavita; B Mohan J Sarat Chandra Babu
      First page: 025013
      Abstract: The use of polyaniline (PANI) and carbon nanotubes (CNTs) as photovoltaic materials has been presented in this paper. The promising properties of PANI and CNTs have encouraged utilizing them in photovoltaic devices and studying their performance. The photovoltaic performance of PANI has been studied with and without CNTs. We found that there is a considerable increase in the short circuit current density from 3.49 to 8.86 mA cm −2 with the use of CNTs in the device and also an increase in power conversion efficiency. The incorporation of CNTs film had led to an efficient transport of photo-generated holes to the anode and suppressed the recombination of free charges generated, thus increasing the efficiency of the device. The performance of the device shows that the PANI and CNTs can be effectively utilized as photovoltaic materials in a photovoltaic cell.

  • Sorption of lead (II), cobalt (II) and copper (II) ions from aqueous
           solutions by γ -MnO 2 nanostructure

    • Authors: Ngoc Chung Le; Dinh Van Phuc
      First page: 025014
      Abstract: Manganese dioxide γ -MnO 2 was synthesized via the reduction–oxidation reaction between KMnO 4 and C 2 H 5 OH at room temperature and characterized with x-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Brunauer–Emmet–Teller nitrogen adsorption (BET–N 2 adsorption). The results showed that γ -MnO 2 was about 10–18 nm in size and the BET surface area was about 65 m 2 g −1 . The feasibility of γ -MnO 2 used as a low cost adsorbent for the adsorption of Pb(II), Co(II) and Cu(II) from aqueous solutions was explored. During the adsorption process, batch technique was used, and the effects of contact time and pH on adsorption efficiency under room temperature were studied. The adsorption data showed that the Freundlich, Langmuir and Redlich-Peterson isotherms are a good model for the sorption of Co(II) and Cu(II), while th...

  • Morphological and biochemical responses of Abelmoschus esculantus (L.)
           Moench to zinc nanoparticles

    • Authors: I B Gokak; T C Taranath
      First page: 025017
      Abstract: The increasing application and use of nanoparticles are directly related to their release in the environment. There has arisen the necessity to study the interactions of nanoparticles with plants and other organisms. The present investigation is an attempt to evaluate the morphological and biochemical responses of Abelmoschus esculentus (L.) Moench to zinc nanoparticles treatment. Seeds were treated with zinc nanoparticles at concentrations of 50 100, 200, 500 ppm. The morphological and biochemical responses recorded include germination percentage, root, shoot length, number of root hairs and number of leaves. Chlorophyll, protein, proline and carbohydrate contents in the leaves of 30-days-old treated plants were estimated. A greater amount of total dissolved solids (TDS) leached out from the seeds soaked in different concentrations of Zn nanoparticles compared to the control. Zinc nanoparticles executed a positive impact on the seed germination. The seed germination perce...

           method

    • Authors: Dung Chinh Trinh; Thi My Dung Dang, Kim Khanh Huynh, Eric Fribourg-Blanc Mau Chien Dang
      First page: 025018
      Abstract: A simple chemical reduction method is used to prepare colloidal bimetallic Cu–Ag core–shell (Cu@Ag) nanoparticles. Polyvinyl pyrrolidone (PVP) was used as capping agent, and ascorbic acid (C 6 H 8 O 6 ) and sodium borohydride (NaBH 4 ) were used as reducing agents. The obtained Cu@Ag nanoparticles were characterized by powder x-ray diffraction (XRD), transmission electron microscopy (TEM) and UV–vis spectrophotometry. The influence of [Ag]/[Cu] molar ratios on the formation of Ag coatings on the Cu particles was investigated. From the TEM results we found that the ratio [Ag + ]/[Cu 2+ ] = 0.2 is the best for the stability of Cu@Ag nanoparticles with an average size of 22 nm. It is also found out that adding ammonium hydroxide (NH 4 OH) makes the obtained Cu@Ag nanoparticles more stable over time when pure deionized water is used as solvent.
