A Sensitive Surface‐enhanced Raman Scattering Method for Determination of Melamine with Aptamer‐modified Nanosilver Probe
Authors: Wen Guiqing , Zhou Lianping , Li Tingsheng , Liang Aihui , Jiang Zhiliang 
Published: April 2012

AbstractThe small nanosilver was prepared by the sodium borohydride procedure. The aptamer was used to modify nanosilver to obtain a nanosilver‐aptamer (AgssDNA) SERS probe for the determination of melamine. In pH 6.6 phosphate buffer solution and in the presence of NaCl, the AgssDNA probe specifically combined with melamine to release nanosilver particles that were aggregated to nanosilver clusters, which exhibited SERS effect at 240 cm−1. When melamine concentration increased, the nanosilver clusters increased, and the SERS intensity at 240 cm−1 increased. The increased SERS intensity ΔI240 cm−1 is linear to melamine concentration in the range of 6.3–403.6 μg·L−1, with a detection limit of 1.2 μg·L−1. This assay was applied to determination of melamine in milk, with satisfactory results.
Preparation, Characterization, Biological Activity and 3D Molecular Modeling of Mn(II), Co(II), Ni(II), Cu(II), Pd(II) and Ru(III) Complexes of Some Sulfadrug Schiff Bases
Authors: EL‐Ghamry H. A. , Sakai K. , Masaoka S. , El‐Baradie K. Y. , Issa R. M. 
Published: April 2012

AbstractMn(II), Co(II), Ni(II), Cu(II), Pd(II) and Ru(III) complexes of Schiff bases derived from the condensation of sulfaguanidine with 2,4‐dihydroxy benzaldehyde (HL1), 2‐hydroxy‐1‐naphthaldehyde (HL2) and salicylaldehyde (HL3) have been synthesized. The structures of the prepared metal complexes were proposed based on elemental analysis, molar conductance, thermal analysis (TGA, DSC and DTG), magnetic susceptibility measurements and spectroscopic techniques (IR, UV‐Vis, and ESR). In all complexes, the ligand bonds to the metal ion through the azomethine nitrogen and α‐hydroxy oxygen atoms. The structures of Pd(II) complex 8 and Ru(III) complex 9 were found to be polynuclear. Two kinds of stereochemical geometries; distorted tetrahedral and distorted square pyramidal, have been realized for the Cu(II) complexes based on the results of UV‐Vis, magnetic susceptibility and ESR spectra whereas octahedral geometry was predicted for Co(II), Mn(II) and Ru(III) complexes. Ni(II) complexes were predicted to be square planar and tetrahedral and Pd(II) complexes were found to be square planar. The antimicrobial activity of the ligands and their metal complexes was also investigated against the gram‐positive bacteria Staphylococcus aures and Bacillus subtilis and gram‐negative bacteria, Escherichia coli and Pesudomonas aeruginosa, by using the agar dilution method. Chloramphenicol was used as standard compound. The obtained data revealed that the metal complexes are more or less, active than the parent ligand and standard. The X‐ray crystal structure of HL3 has been also reported.
Preparation and Characterization of Fe3O4/Ethiodized‐oil Magnetic Fluids Used in Arterial Embolization Hyperthermia
Authors: Luo Zhi , Wang Yiming , Hong Ruoyu , Li Hongzhong 
Published: April 2012

AbstractFe3O4 nanoparticles (NPs) were prepared by the co‐precipitation of Fe3+ and Fe2+ with ammonium hydroxide, and were modified by four different surfactants. The modified Fe3O4 NPs were characterized by Fourier transform infrared spectroscopy, X‐ray powder diffraction, transmission electron microscopy and vibrating sample magnetometer. Then, the modified Fe3O4 NPs were dispersed in ethiodized‐oil by mechanical agitation and ultrasonic vibration to obtain stable Fe3O4/ethiodized‐oil magnetic fluids (MFs). The magnetic properties and rheological properties of the MFs were measured using a Gouy magnetic balance and a rotational rheometer, respectively. The saturation magnetization of the Fe3O4 modified by oleic acid was 52.1 emu/g. Furthermore, the result showed that the inductive heating effect of oleic acid stabilized Fe3O4/ethiodized‐oil MF was remarkable and it only took 650 s for the temperature rising from 25°C to 65°C. The specific absorption rate of the MF was 50.16 W/(g of Fe). It had a potential application in arterial embolization hyperthermia.
Chlorine‐Doped ZnSe Nanoribbons with Tunable n‐Type Conductivity as High‐Gain and Flexible Blue/UV Photodetectors
Authors: Wang Zhi , Jie Jiansheng , Li Fangze , Wang Li , Yan Tianxin , Luo Linbao , Nie Biao , Xie Chao , Jiang Peng , Zhang Xiwei , Yu Yongqiang , Wu Chunyan 
Published: April 2012

AbstractAlthough significant progress has been achieved in the fabrication of ZnSe nanostructures with various structures and morphologies, it remains a major challenge to rationally tune their transport properties for applications in future nano‐optoelectronic devices. The synthesis of chlorine‐doped ZnSe nanoribbons (NRs) with tunable n‐type conductivity is achieved by a thermal co‐evaporation method. The ZnSe:Cl NRs have single‐crystal wurtzite structure and [120] orientation, which also show high crystalline quality and structural integrity comparable with the undoped NRs. Electrical measurements on a single ZnSe:Cl NR reveal a substantial enhancement of the conductivity upon Cl doping. The conductivity could be further tuned by adjusting the doping level. In addition, highly sensitive blue/UV photodetectors are constructed based on the ZnSe:Cl NRs. The devices exhibit an extremely high gain of approximately 106, and the UV response could be enhanced through a fast annealing process in air. By replacing the rigid SiO2/Si substrate with a PET substrate, flexible ZnSe:Cl NR photodetectors with excellent stability and durability under strain are realized. It is expected that the ZnSe:Cl NRs with tunable n‐type conductivity will have important applications in the new generation nano‐optoelectronic devices.
Spin‐Polarized Symmetric Electron‐Hole Quantum Bilayers: Finite width Effect
Authors: Nayak M. G. , Saini L. K. 
Published: April 2012

AbstractIn this paper, the effect of finite width on ground‐state properties of a spin‐polarized symmetric electron‐hole quantum bilayers (EHBL) system is investigated at zero temperature. The quantum self‐consistent mean‐field approximation of Singwi, Tosi, Land and Sjölander (qSTLS) is adopted to explore intra‐ and interlayer properties such as the pair‐correlation function, the static density susceptibility, the local‐field corrections and the ground‐state energy. Interestingly, we noticed that due to the inclusion of finite width, the critical density for the onset of Wigner crystal (WC) phase is now lowered as compared to the recent spin‐polarized EHBL system without finite width and unpolarized EHBL system with finite width. Further, spin‐polarization effect is seem to introduce a marked change in the ground‐state energy of EHBL system as compared to that of unpolarized system. Results of ground‐state energy are also compared with the recent EHBL system without finite width (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Non‐Ideal Dust Structures in Cryogenic Complex Plasmas
Authors: Antipov S. N. , Vasiliev M. M. , Petrov O. F. 
Published: April 2012

AbstractThe possibility of the formation of dust structures in cryogenic environment at 4.2‐77 K was proved experimentally in the previous researches of cryogenic complex (dusty) plasma [1–5]. It was revealed from the experiments, among others, that the dust structures with high concentration of dust particles can be formed, in which interparticle distance is comparable with particle size ‐ super dense dusty plasma structures. Such structures had exotic properties such as globular (spherical) form, free boundaries, etc. In the present work new results on the experimental investigations of new phenomenon of spheroidizing ‐ process of the dust structure transition to compact globular shape at cryogenic temperatures ‐ were presented. Possible nature of such phenomenon is discussed (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Shear Viscosity of Liquid‐Phase Yukawa Plasmas from Molecular Dynamics Simulations on Graphics Processing Units
Authors: Budea Á. , Derzsi A. , Hartmann P. , Donkó Z. 
Published: April 2012

AbstractWe have carried out million‐particle equilibrium molecular dynamics simulations of 3‐dimensional Yukawa liquids in order to determine the shear viscosity coefficient. The computations have been executed on Graphics Processing Unit (GPU) architectures with our largely parallelized code. The results cover the strongly coupled liquid phase, with Γ up to the vicinity of the freezing transition, for the 1 ≤ κ ≤ 3 domain of the screening parameter of the Yukawa potential. The good agreement of the present results with those obtained from earlier simulations of significantly smaller systems (consisting of several hundred to several thousand particles) verifies that the viscosity data derived in these smaller scale simulations are also acceptable (© 2011 WILEY‐VCH Verlag GmbH & Co.
