  • Aluminum nitride photonic crystals and microdiscs for ultra-violet
           nanophotonics

    • Authors: D Néel; I Roland, X Checoury, M El Kurdi, S Sauvage, C Brimont, T Guillet, B Gayral, F Semond P Boucaud
      First page: 023001
      Abstract: Processing of group III-nitride materials such as AlN in the form of photonic crystals or microdiscs opens new perspectives for basic cavity quantum electrodynamic studies or the development of novel devices operating in the ultra-violet range. These devices can be either passive or active by embedding self-assembled GaN quantum dots. We review the recent progress achieved in the field of nitride-based microresonators for UV nanophotonics.

  • Quantum theory of plasmon

    • Authors: Van Hieu Nguyen; Bich Ha Nguyen
      First page: 025001
      Abstract: Since very early works on plasma oscillations in solids, it was known that in collective excitations (fluctuations of the charge density) of the electron gas there exists the resonance appearing as a quasiparticle of a special type called the plasmon. The elaboration of the quantum theory of plasmon in the framework of the canonical formalism is the purpose of the present work. We start from the establishment of the Lagrangian of the system of itinerant electrons in metal and the definition of the generalized coordinates and velocities of this system. Then we determine the expression of the Hamiltonian and perform the quantization procedure in the canonical formalism. By means of this rigorous method we can derive the expressions of the Hamiltonians of the interactions of plasmon with photon and all quasiparticles in solid from the first principles.

  • The performance measure of GS-DG MOSFET: an impact of metal gate work
           function

    • Authors: S K Mohapatra; K P Pradhan, P K Sahu M R Kumar
      First page: 025002
      Abstract: The quantitative assessment of the nanoscale gate stack double gate (GS-DG) MOSFET performance values are numerically calculated with different gate metal work functions ( Φ m = 4.52 eV, 4.6 eV, 4.7 eV). The effect of electrostatic control on dc, analog and RF figures of merit (FOMs) which includes subthreshold slope (SS), drain induced barrier lowering (DIBL), transconductance generation factor (TGF), early voltage ( V EA ), intrinsic gain (A V ), cut off frequency ( f T ) and transconductance frequency product (TFP), gain frequency product (GFP) and gain transconductance frequency product (GTFP) have been investigated for the model GS-DG MOSFET. Higher TGF and A V was achieved with Φ m = 4.6 eV for the device. For a better comparison among the analog/RF FOMs, the threshold voltage ( V th ) is maintained at a constant value for different work function cases. To achieve a constan...

  • Effect of samarium nanoparticles on the electrical transport properties of
           polyaniline

    • Authors: K Gupta; P S Mukherjee, A K Meikap P C Jana
      First page: 025003
      Abstract: A comprehensive study of the effect of samarium nanoparticles on electrical transport properties of polyaniline has been reported. Samples are prepared by chemical oxidative polymerization of aniline in the presence of samarium nanoparticles and characterized by XRD, FESEM, EDS, HRTEM and UV-Vis spectrometer. When the samarium content in polyaniline matrix increases, energy band gap decreases and conductivity increases by four orders of magnitude. A transformation of negative to positive magnetoconductivity has been observed by incorporating samarium nanoparticles in polyaniline matrix. Two types of activation behavior have been observed from the dielectric relaxation behavior. AC conductivity strongly depends on magnetic field. Although, at present, no theoretical model is found in literature to explain directly the behavior of ac conductivity in the presence of magnetic field, it may be due to the change of grain and interfacial boundary resistances by magnetic field.

  • Nanostructured PbO 2 -PANi composite materials for electrocatalytic
           oxidation of methanol in acidic sulfuric medium

    • Authors: Thi Thanh Thuy Mai; Thi Binh Phan, Thi Tot Pham Huu Hieu Vu
      First page: 025004
      Abstract: Hybrid materials based on PbO 2 and PANi were prepared by cyclic voltammetry combined with chemical method. Firstly, PbO 2 and PbO 2 -PANi were deposited on stainless steel by cyclic voltammetry (CV) at a scan rate of 100 mV s −1 . Next, they were immersed in acidic aniline solution (0.1 M) to form new fresh PbO 2 -PANi composites. The properties of materials were characterized by x-ray diffraction, IR- spectroscopy, scanning electron microscopy and transmission electron microscopy. The electrocatalytic oxidation for methanol of all PbO 2 -PANi layers was investigated in acidic medium by potentiodynamic measure at a scan rate of 100 mV s −1 in the range of 1.4 V to 2.2 V versus Ag/AgCl/saturated KCl electrode. The obtained results indicated that the composites prepared by above combined method could significantly enhance the electrocatalysis for oxidation of methanol.

  • Capacitance behavior of nanostructured ϵ -MnO 2 /C composite
           electrode using different carbons matrix

    • Authors: Van Man Tran; An The Ha My Loan Phung Le
      First page: 025005
      Abstract: In this work nanostructured ϵ -MnO 2 /C composite electrode was synthesized via the reduction reaction of potassium permanganate. A wide range of carbons such as mesoporous carbon (MC), graphite (GC), super P carbon (super P) and Vulcan carbon (VC) were used in order to enhance the interfacial electrical conductivity and the electrochemical capacitance of the composite electrodes. Physical properties, structure and specific surface area of electrode materials were investigated by scanning electron microscopy (SEM), x-ray diffraction and nitrogen adsorption measurements. The capacitance behavior of MnO 2 /C materials was studied in aqueous and non-aqueous solution using cyclic voltammetry, galvanostatic charge/discharge and impedance spectroscopy measurements. The composite electrode exhibits the highest capacitance at 30 wt% activated carbon. Among different carbons used, the maximum capacitance of MnO 2 /super P electrode is as high as 205 F g

  • Mechanistic aspects of biogenic synthesis of CdS nanoparticles using
           Bacillus licheniformis

    • Authors: R M Tripathi; Akhshay Singh Bhadwal, Priti Singh, Archana Shrivastav, M P Singh B R Shrivastav
      First page: 025006
      Abstract: A novel eco-friendly effort has been made for the synthesis of cadmium sulfide (CdS) nanoparticles using bacterial biomass. Although some articles have been reported on CdS nanoparticles synthesis by bacteria, here we have synthesized CdS nanoparticles using non-pathogenic bacteria Bacillus licheniformis MTCC 9555. UV-Vis spectroscopy was carried out to confirm the formation of CdS nanoparticles; the peak occurring at 368 nm gives the indication of synthesis of CdS nanoparticles. The size and morphology of the synthesized CdS nanoparticles were analyzed by transmission electron microscopy (TEM) and the nanoparticles are found to have a narrow size of 5.1 ± 0.5 nm with spherical morphology. Further, the nanoparticles were examined by energy dispersive x-ray (EDX) spectroscopy to identify the presence of elements and confirmed the existence of Cd and S in single nanoparticles. X-ray diffraction (XRD) analysis exhibited 2 θ values corresponding to CdS nanocrystals. Four...

  • Reusable nanocomposite of CoFe 2 O 4 /chitosan- graft -poly(acrylic acid)
           for removal of Ni(II) from aqueous solution

    • Authors: Van Cuong Nguyen; Thi Kim Ngoc Huynh
      First page: 025007
      Abstract: In this paper, CoFe 2 O 4 /chitosan- graft -poly(acrylic acid) (CoFe 2 O 4 /CS- graft -PAA) nanocomposites were prepared successfully by coprecipitation of the compounds in alkaline solution and were used for removal of nickel (II) ions from aqueous solution. The sorption rate was affected significantly by the initial concentration of the solution, sorbent amount, and pH value of the solution. Batch experiments were conducted to investigate the adsorption capacity under different initial concentration (ranging from 25 to 150 mg L −1 ), solution pH (4.1, 5.3, 6.4 and 7.6), and contact time. These nanocomposites can be recycled conveniently from water with the assistance of an external magnet because of their exceptional properties. The prepared nanocomposites were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), x-ray powder diffraction (XRD), and thermogravimetric analysis (...

  • Synthesis and self-assembly properties of fulleropyrrolidine prepared by
           Prato reaction

    • Authors: Khanh Hy Le Ho; Stéphane Campidelli
      First page: 025008
      Abstract: Molecular self-assembly is considered as a promising way to control the manufacture of new materials and their integration into hybrid devices with novel properties. In this work we have synthesized a fulleropyrrolidine bearing a phenylacetylene moiety via the Prato reaction. The characterization of the fulleropyrrolidine by nuclear magnetic resonance and optical spectroscopy is reported, and its self-assembly by crystallization study has been investigated according to the used solvents. If the solvent that effectively solubilizes fullerene derivative is tetrahydrofurane, the nano-square plates with 1–3 μ m in length and 50–100 nm in thickness are formed, while if the solvent is toluene, 5 μ m diameter ‘nano-flowers’ are obtained.

    • Authors: Nguyen Van Hieu
      First page: 029301
      Abstract: This book belongs to the series 'Perspectives in Nanotechnology' of CRC Press. It is a scientific encyclopedic monograph and, at the same time, a practical guide on two overlapping, closely related, very promising, recently emerging and rapidly developing areas of science and technology: medical nanotechnology consisting of a variety of nanoscale technologies applied to medicine and biomedical engineering, and nanomedicine being a newly emerging area of medicine which was created on the basis of the achievements of the research of molecular processes at the cellular level. The book consists of three parts. Part I with the title 'Perspectives' has three short chapters. In chapter 1 the author presents the scientific basis of medical nanotechnology and nanomedicine and discusses their societal implications. The main content of chapter 2 is the brief history of nanomedicine and the milestones of medical nanotechnology. The research initiatives, important public...
