  • Application of nanoelements in plant nutrition and its impact in
           ecosystems

    • Authors: América Berenice Morales-Díaz; Hortensia Ortega-Ortíz, Antonio Juárez-Maldonado, Gregorio Cadenas-Pliego, Susana González-Morales Adalberto Benavides-Mendoza
      First page: 013001
      Abstract: Agriculture stands to benefit from nanotechnology in areas such as combating pests and pathogens, regulating the growth and quality of crops, and developing intelligent materials and nanosensors. The objective of this paper is to provide an overview of the use of nanomaterials (NMs) and nanoparticles (NPs) in plant nutrition, highlighting their advantages and potential uses, but also reviewing their possible environmental destination and effects on ecosystems and consumers. NPs and NMs have been shown to be an attractive alternative for the manufacture of nanofertilizers (NFs), which are more effective and efficient than traditional fertilizers. Because of their impact on crop nutritional quality and stress tolerance in plants, the application of NFs is increasing. However, there are virtually no studies on the potential environmental impact of NPs and NMs when used in agriculture. These studies are necessary because NPs and NMs can be transferred to ecosystems by various pathwa...

  • Perspectives for high-performance permanent magnets: applications,
           coercivity, and new materials

    • Authors: Satoshi Hirosawa; Masamichi Nishino Seiji Miyashita
      First page: 013002
      Abstract: High-performance permanent magnets are indispensable in the production of high-efficiency motors and generators and ultimately for sustaining the green earth. The central issue of modern permanent magnetism is to realize high coercivity near and above room temperature on marginally hard magnetic materials without relying upon the critical elements such as heavy rare earths by means of nanostructure engineering. Recent investigations based on advanced nanostructure analysis and large-scale first principles calculations have led to significant paradigm shifts in the understandings of coercivity mechanism in Nd–Fe–B permanent magnets, which includes the discovery of the ferromagnetism of the thin (2 nm) intergranular phase surrounding the Nd 2 Fe 14 B grains, the occurrence of negative (in-plane) magnetocrystalline anisotropy of Nd ions and some Fe atoms at the interface which degrades coercivity, and visualization of the stochastic behaviors of magnetization in t...

  • Photocatalytic performance of crystalline titania polymorphs in the
           degradation of hazardous pharmaceuticals and dyes

    • Authors: Thi Thuong Huyen Tran; Hendrik Kosslick, Axel Schulz Quang Liem Nguyen
      First page: 015011
      Abstract: In the present work, nano-sized TiO 2 polymorphs (anatase, brookite, and rutile) were synthesized via hydrothermal treatment of an amorphous titania. Three polymorphs were characterized by XRD, Raman spectroscopy, SEM, UV–Vis DRS, and N 2 -sorption measurements. The photocatalytic degradation experiments were performed with low catalyst concentration, high organic loading under a 60 W UV–Vis solarium lamp irradiation. The photocatalytic degradation was monitored by UV–Vis spectroscopy and TOC measurements. Cinnamic acid, ibuprofen, phenol, diatrizoic acid and the dyes rhodamine B and rose bengal were used as model pollutants. The formation of intermediates was studied by ESI-TOF-MS measurements. The presence of active species was checked by quenching the activity by addition of scavengers. The photocatalytic activity decreased in the order: anatase  ⩾  brookite  >  rutile, with growing recalcitrance of organic compounds. The differences in the activity are ...

  • Optimal joint remote state preparation in the presence of various types of
           noises

    • Authors: Van Hop Nguyen; Thi Bich Cao Ba An Nguyen
      First page: 015012
      Abstract: A main obstacle faced by any quantum information processing protocol is the noise that degrades the desired coherence/entanglement. In this work we study by means of Kraus operators the effect of four typical types of noises on the quality of joint remote state preparation of a single-qubit state using a three-qubit Greenberger–Horne–Zeilinger-type state as the initial quantum channel. Assuming that two of the three involved qubits independently suffer a type of noise, we derive analytical expressions not only for the optimal averaged fidelities but also for the boundaries in phase space of the domains in which the joint remote state preparation protocol outperforms the classical one. Detailed discussion is given for each of the total 16 noisy scenarios. We also provide physical interpretation for the obtained results and outline possible future topics.

  • Study on the critical properties of thin magnetic films using the clock
           model

    • Authors: T-L H Nguyen; V Thanh Ngo
      First page: 015013
      Abstract: We study the critical behaviour of very thin magnetic films. This system can be described by the q -state clock model. In order to determine the critical exponents of the system when there exists the Berezinskii–Kosterlitz–Thouless phase between the two phase transitions, we introduce a new technique for calculating the order parameter. The simulation is performed by very high-resolution Monte Carlo method with including the Wang–Landau algorithm. The results showed that the Berezinskii–Kosterlitz–Thouless phase starts to occur when ##IMG## [http://ej.iop.org/images/2043-6262/8/1/015013/ansnaa5981ieqn001.gif] {$q\geqslant 3$} with a small symmetry breaking field. We obtained not only the critical exponents of a common transition at high temperature but also the ones of unclear transition at low temperature.

  • Green synthesis of silver nanoparticles with antibacterial activities
           using aqueous Eriobotrya japonica leaf extract

    • Authors: Bo Rao; Ren-Cheng Tang
      First page: 015014
      Abstract: An eco-friendly approach for the preparation of silver nanoparticles (AgNPs) from silver nitrate solution using aqueous Eriobotrya japonica leaf extract was investigated. The reduction of silver ions in solution was monitored using UV–visible absorption spectroscopy, and the surface plasmon resonance of AgNPs at 435 nm was observed. The proper condition to biosynthesize AgNPs using E. japonica leaf extract was optimized by UV–visible absorption spectroscopy and dynamic light scattering measurement (DLS). The biosynthesised nanoparticles were characterised using transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), DLS, x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). XRD and EDX analyses confirmed the crystalline character of AgNPs and the presence of elemental silver. The prepared AgNPs were spherical in shape, and their average particle size determined by TEM was about 20...

  • Investigation of oxygen vacancies in Ce coupled TiO 2 nanocomposites by
           Raman and PL spectra

    • Authors: J Dhanalakshmi; S Iyyapushpam, S T Nishanthi, M Malligavathy D Pathinettam Padiyan
      First page: 015015
      Abstract: CeO 2 –TiO 2 nanocomposites with different Ce weight percentages (2, 4, 6 and 8%) were synthesized by sol-gel method. The influence of cerium inclusion on the structural, morphological, optical properties and elemental composition has been analyzed via XRD, BET surface area analysis, UV-DRS, HR-SEM, EDAX, TEM, Raman and photoluminescence spectra. The structural study showed that all the CeO 2 –TiO 2 nanocomposites crystallized in tetragonal structure with anatase phase. Morphological study revealed that the nanocomposites are in spherical shape with size between 13–15 nm. Raman and PL spectra confirmed the presence and influence of oxygen vacancy defects. The adsorption ability of the CeO 2 –TiO 2 nanocomposites was investigated for congo red dye under dark condition. CeO 2 –TiO 2 nanocomposites have enhanced adsorptive performance in comparison with bare TiO 2 nanoparticles. The enhanced adsor...

  • Effect of coating mild steel with CNTs on its mechanical properties and
           corrosion behaviour in acidic medium

    • Authors: Mahmud Abdulmalik Abdulrahaman; Oladiran Kamaldeeen Abubakre, Saka Ambali Abdulkareem, Jimoh Oladejo Tijani, Ahmed Aliyu Ayo Samuel Afolabi
      First page: 015016
      Abstract: The study investigated the mechanical properties and corrosion behaviour of mild steel coated with carbon nanotubes at different coating conditions. Multi-walled carbon nanotubes (MWCNTs) were synthesized via the conventional chemical vapour deposition reaction using bimetallic Fe–Ni catalyst supported on kaolin, with acetylene gas as a carbon source. The HRSEM/HRTEM analysis of the purified carbon materials revealed significant reduction in the diameters of the purified MWCNT bundles from 50 nm to 2 nm and was attributed to the ultrasonication assisted dispersion with surfactant (gum arabic) employed in purification process. The network of the dispersed MWCNTs was coated onto the surfaces of mild steel samples, and as the coating temperature and holding time increased, the coating thickness reduced. The mechanical properties (tensile strength, yield strength, hardness value) of the coated steel samples increased with increase in coating temperature and holding time. Comparing t...

  • Green synthesis, characterization and biological activities of silver
           nanoparticles from alkalinized Cymbopogon citratus Stapf

    • Authors: Emmanuel Ajayi; Anthony Afolayan
      First page: 015017
      Abstract: Silver nanoparticles (AgNPs) have been synthesized from the alkalinized leaf extract of Cymbopogon citratus , also known as lemon grass (LG), and characterized for their size and shape using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The total formation of the AgNPs was observed visually with a color change from yellow to brownish-black. Fourier transform infrared spectroscopy (FTIR) and energy dispersive x-ray spectroscopy (EDS/EDX) were conducted to determine the various functional groups and the concentration of metal ions in the nanoparticles. The data analysis showed spherically shaped nanoparticles with a size of 10–33 nm, as revealed by TEM, thereby complementing the result for SEM. FTIR identifies the ethylene group as a reducing and capping agent for the formation of the nanoparticles. The x-ray diffraction pattern confirmed the presence of silver crystallites as well as their size, further confirming the result of the TEM. AgNP...

  • Intrinsic phonon properties of double-walled carbon nanotubes

    • Authors: H N Tran; D I Levshov, V C Nguyen, M Paillet, R Arenal, X T Than, A A Zahab, Y I Yuzyuk, N M Phan, J-L Sauvajol T Michel
      First page: 015018
      Abstract: Double-walled carbon nanotubes (DWNT) are made of two concentric and weakly van der Waals coupled single-walled carbon nanotubes (SWNT). DWNTs are the simplest systems for studying the mechanical and electronic interactions between concentric carbon layers. In this paper we review recent results concerning the intrinsic features of phonons of DWNTs obtained from Raman experiments performed on index-identified DWNTs. The effect of the interlayer distance on the strength of the mechanical and electronic coupling between the layers, and thus on the frequencies of the Raman-active modes, namely the radial breathing-like modes (RBLMs) and G-modes, are evidenced and discussed.
