  • Bactericidal activity and silver release of porous ceramic candle filter
           prepared by sintering silica with silver nanoparticles/zeolite for
           water disinfection

    • Authors: Thuy Ai Trinh Nguyen; Van Phu Dang, Ngoc Duy Nguyen, Anh Quoc Le, Duc Thanh Nguyen Quoc Hien Nguyen
      First page: 035001
      Abstract: Porous ceramic candle filters (PCCF) were prepared by sintering silica from rice husk with silver nanoparticles (AgNPs)/zeolite A at about 1050 °C to create bactericidal PCCF/AgNPs for water disinfection. The silver content in PCCF/AgNPs was of 300–350 mg kg −1 determined by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and the average pore size of PCCF/AgNPs was of 50–70 Å measured by Brunauer–Emmett–Teller (BET) method. The bactericidal activity and silver release of PCCF/AgNPs have been investigated by flow test with water flow rate of 5 L h −1 and initial inoculation of E . coli in inlet water of 10 6 CFU/100 mL. The volume of filtrated water was collected up to 500 L. Results showed that the contamination of E . coli in filtrated water was

  • Quantum theory of plasmon energy spectra in electron gases of bulk metal
           and metallic nanostructures

    • Authors: Van Hieu Nguyen; Bich Ha Nguyen
      First page: 035004
      Abstract: The present work is an attempt to formulate the quantum theory of plasmons in metallic structures starting from basic laws of electrodynamics and quantum theory as first principles. In particular, the dynamical integral equation of plasmon in any metallic structure was established. As a test, this general dynamical equation was used to determine the dispersion of plasmon in bulk metal and the obtained result completely agreed with the formula derived in conventional theories. Then the general method for determining the energy spectrum of plasmons in any metallic nanostructure was presented.

  • Functionalization of reduced graphene oxide by electroactive polymer for
           biosensing applications

    • Authors: Le Huy Nguyen; Tuan Dzung Nguyen, Vinh Hoang Tran, Thi Thu Huyen Dang Dai Lam Tran
      First page: 035005
      Abstract: A novel biosensing platform was designed by the functionalizing reduced graphene oxide sheets (rGO) with electroactive copolymer juglone. The composite film showed well-defined, stable electroactivity in a biocompatible buffer medium. Square wave voltammetry is used to record the redox signal for DNA hybridization. Current increase upon hybridization ( signal - on ) evidenced that short DNA target as well as polymerase chain reaction (PCR), so called ‘real sample’ products, related to different lineages of Mycobacterium tuberculosis strain. The signal - on reached ∼40% with 1 nM of short DNA (25 mer) target, while PCR product (Africanum, EAI and Beijing strains) produced a current change of ∼20%.

  • Study of RF performance of surrounding gate MOSFET with gate overlap and
           underlap

    • Authors: Angsuman Sarkar
      First page: 035006
      Abstract: In this paper a simulation study is used to investigate the RF performance of surrounding gate (SRG) MOSFET. The effect of nonsymmetrical gate structure caused by non- ideality in fabrication process has also been taken care into consideration. The important RF figure-of-merits such as unity-gain cut-off frequency f T and maximum operating frequency f MAX are studied with the help of a 2D device simulator. Their trends related to the variation of different design parameters such as radius, oxide thickness, gate length, and doping along the downscaling have also been reported.

  • Tunable morphological properties of silver enriched platinum allied
           nanoparticles and their catalysed reduction of p-nitrophenol

    • Authors: Joseph Adeyemi Adekoya; Enock Olugbenga Dare Michael Adediran Mesubi
      First page: 035007
      Abstract: A robust polymer based and polyol mediated procedure to synthesize nanobimetallic particles has been modified to produce core–shell and alloy Ag/Pt nanoparticles with tunable properties. Novel three-dimensional (3D) quasi nanocubes entangled in nanowebs were produced by rapid solution phase transformation with hot addition of absolute ethanol. The optical characterization showed extinction of plasmon resonance band occurring with incremental feeding ratio of Pt source in all cases. Transmission electron microscope (TEM) and high resolution transmission electron microscope (HRTEM) images revealed that the shape, size and size distribution of as-prepared silver platinum nanoparticles depended on the stabilizer or capping agent, mole ratio of metal ion sources, temperature and time of reaction. Meanwhile, catalytic activity was highest in the reduction of p-nitrophenol in the presence of polyvinylpyrrolidone/diethylene glycol stabilized Ag/Pt nanoparticles.

  • Antioxidant and anti-inflammatory activities of silver nanoparticles
           biosynthesized from aqueous leaves extracts of four Terminalia
           species

    • Authors: Hanaa Mohamed El-Rafie; Manal Abdel-Aziz Hamed
      First page: 035008
      Abstract: The environmentally friendly synthesis of nanoparticles process is a revolutionary step in the field of nanotechnology. In recent years plant mediated biological synthesis of nanoparticles has been gaining importance due to its simplicity and eco-friendliness. In this study, a simple and an efficient eco-friendly approach for the biosynthesis of stable, monodisperse silver nanoparticles using aqueous extracts of four Terminalia species, namely, Terminalia catappa , Terminalia mellueri , Terminalia bentazoe and Terminalia bellerica were described. The silver nanoparticles were characterized in terms of synthesis, capping functionalities (polysaccharides, phenolics and flavonoidal compounds) and microscopic evaluation by UV-visible spectroscopy, Fourier transform infrared spectroscopy and transmission electron microscopy. The results showed a simple and feasible approach for obtaining stable aqueous monodispersive silver nanoparticles. Furthermore, ...

  • Hydrogen generation by photoelectrochemical effect of the Cu-doped TiO 2
           photoanode

    • Authors: Ngoc Tai Ly; Thi Hoa Dao, Le Hong Hoang To, Dinh Lam Vu Van Hong Le
      First page: 035009
      Abstract: TiO 2 film photoanodes with a size of 1 × 1 cm 2 were fabricated by a spin coating method. Cu-doped TiO 2 powder with various Cu concentrations (0.2, 0.4, 0.6 and 0.8 at%) and surfactant were used as starting materials in coating Cu-doped TiO 2 thin films onto FTO/glass substrate. Crystalline structure of TiO 2 material, microstructure of the photoanode films and their thickness were identified by x-ray diffraction and Raman scattering. Hydrogen generation from water by photoelectrochemical effect in the visible light was observed by recording I/V characteristics of the photoanode in dark and light regimes. The obtained results have shown that the hydrogen generation efficiency of photoanode nonlinearly depends on Cu concentration. The nonlinear dependence of the hydrogen generation efficiency may be due to a change of resistivity of the film photoanode that is related with the random distribution of the hetero-junction between in...

  • A fluid density sensor based on a resonant tube

    • Authors: Yong Zhu; Dzung Viet Dao Peter Woodfield
      First page: 035010
      Abstract: A fluid density sensor based on resonance frequency change of a metallic tube is presented. The sensor has been developed without using a complex micro-fabrication process. The sensor is able to identify fluid types/contaminations and improve the performance by reducing testing time, decreasing complexity of testing equipment and reducing sample sizes. The sensor can measure the resonance frequency of its own structure and determine the change in resonance frequency due to the subsequent sample inside the tube. Numerical modelling, analytical modelling and physical testing of a prototype sensor showed comparable results for both the magnitude and resonance frequency shift. The modelling results yielded a resonance frequency shift of 200 Hz from 9.87 kHz to 9.67 kHz after the water was filled into the tube. The actual testing illustrated a resonance frequency change of 280 Hz from 9.11 kHz to 8.83 kHz. The ultimate aim of the work is to determine resonance frequencies of desired s...

  • Preparation of platinum nanoparticles in liquids by laser ablation method

    • Authors: The Binh Nguyen; Thanh Dinh Nguyen, Quang Dong Nguyen Thi Trinh Nguyen
      First page: 035011
      Abstract: Platinum (Pt) nanoparticles were prepared in solutions of ethanol and TSC (trisodium citrate—Na 3 C 6 H 5 O 7 .nH 2 O) in water by laser ablation method using Nd:YAG laser. The role of laser fluence, laser wavelength and concentration of surfactant liquids in laser ablation process were investigated. The morphology, size distribution and optical properties of the Pt nanoparticles (NPs) were observed by transmission electron microscopy (TEM), UV-vis spectrometer and x-ray diffraction measurements. The average diameter of Pt NPs prepared in ethanol and TSC solutions ranges around 7–9 nm and 10–12 nm, respectively. The results showed advantages of the laser ablation method.
