Immobilization of Mycoplana sp. MVMB2 Isolated from Petroleum Contaminated Soil onto Papaya Stem (Carica papaya L.) and Its Application on Degradation of Phenanthrene
Authors: Brinda Lakshmi Mahalingam , Muthukumar Karuppan , Velan Manickam 
Published: July 2012

AbstractThis study presents the degradation of phenanthrene using immobilized Mycoplana sp. MVMB2 isolated from contaminated soil. Papaya stem pretreated by two stage processes, treating with acid or alkali and drying, was used for the immobilization of Mycoplana sp. Alkali pretreated papaya stem was found to be most effective in cell uptake compared to acid treated one. The maximum immobilization capacity at various physiochemical conditions for the alkali pretreated papaya stem was found to be at 320 min time, pH 6.5, 30°C temperature, and 18.6 × 106 cells/mL initial concentrations. The adsorption mechanism of Mycoplana sp. MVMB2 on pretreated papaya stem was assessed using various kinetic and isotherm models. The immobilization of Mycoplana sp. MVMB2 on to pretreated papaya stem was corroborated by scanning electron microscopy and Fourier transformed IR spectroscopy analysis. The performance of immobilized cells in batch reactor showed more than 95% phenanthrene degradation within 72 h, whereas, free cells were found to require 120 h. The immobilized cells also showed better degradation performance in the packed column study.
Face detection algorithm based on hybrid Monte Carlo method and Bayesian support vector machine
Authors: Wang Liejun , Zhang Taiyi , Jia Zhenhong , Ding Liang 
Published: July 2012

SUMMARYWith distinct advantages in resolving the problems of small sample, nonlinear, high dimension learning, the support vector machine (SVM) has been widely applied in face detection and face recognition. In fact, a large number of facial images were needed to train the SVM algorithms. With the rising of training image numbers, the training complexity of SVM was increased by way of geometric series. In this paper, the hybrid Monte Carlo method of the Bayesian support vector machine is proposed. This method solves the problems of high‐dimension and long training time effectively. Experimental results show that the method greatly reduces the training time of face detection algorithm and obtains more accurate face detection effect. Copyright © 2012 John Wiley & Sons, Ltd.
Energy‐efficient resource allocation in multiuser relay‐based OFDMA networks
Authors: Zhang Jianhua , Jiang Yun , Li Xiaofan 
Published: July 2012

SUMMARYAlthough the demand for battery capacity on mobile devices has grown with the increase in high data rate applications, battery technology has not kept up with this demand. Therefore, the growth in energy demand coupled with global warming provide a new trend in wireless communication known as energy‐efficient transmission. In this paper, the energy‐efficient resource allocation for a two‐hop uplink multiuser relay‐based system is studied. We adopt the orthogonal frequency division multiplexing as the physical layer modulation technique. Assuming that the base station has all the channel state information, an energy efficiency optimization problem by joint subcarrier assignment, bit and power allocation is formulated. We first develop a near‐optimal resource allocation scheme to maximize the overall energy efficiency; then, an efficient resource allocation algorithm is provided to solve the problem with relatively low computational complexity. Furthermore, fairness constraint among users is imposed on the system to guarantee each user's QoS. Our joint resource allocation algorithm is proved to achieve a considerable improvement in terms of energy‐saving and simultaneously decreases outage probability by simulation results.

Substituent Effect on the π Linkers in Triphenylamine Dyes for Sensitized Solar Cells: A DFT/TDDFT Study
Authors: Xu Jie , Zhu Ligen , Fang Dong , Chen Biao , Liu Li , Wang Luoxin , Xu Weilin 
Published: July 2012

AbstractA series of metal‐free organic donor–π bridge–acceptor dyes are studied computationally using density functional theory (DFT) and time‐dependent DFT (TDDFT) approaches to explore their potential performances in dye‐sensitized solar cells (DSSCs). Taking triphenylamine (TPA) and cyanoacrylic acid moieties as donor and acceptor units, respectively, the effects of different substituents of the π linkers in the TPA‐based dyes on the energy conversion efficiency of the DSSCs are theoretically evaluated through optimized geometries, charge distributions, electronic structures, simulated absorption spectra, and free energies of injection. The results show that the molecular orbital energy levels and electron‐injection driving forces of the TPA dyes can be tuned by the introduction of substituents with different electron‐withdrawing or ‐donating abilities. The electron‐withdrawing substituent always lowers the energies of both frontier orbitals, while the electron‐donating one heightens them simultaneously. The efficiency trend of these TPA derivatives as sensitizers in DSSCs is also predicted by analyzing the light‐harvesting efficiencies and the free energies of injection. The following substituents are shown to increase the efficiency of the dye: OMe, OEt, OHe, and OH.
Preparation and magnetic properties of CoWO4 nanocrystals
Authors: Deng Jiwei , Chang Liao , Wang Ping , Zhang Endi , Ma Jianmin , Wang Taihong 
Published: July 2012

AbstractCobalt tungstate (CoWO4) nanocrystals with an average size of 20–50 nm were synthesized via a template‐ or surfactant‐free hydrothermal route. The crystal structure and morphology of the as‐synthesized CoWO4 sample were characterized by X‐ray diffraction, scanning electron microscopy and transmission electron microscopy. Magnetic measurements on the as‐synthesized CoWO4 nanocrystals indicate a Néel temperature (TN) of ∼40 K. This lower TN may be a result of the nanostructured particles that reduce the exchange coupling. The new synthetic route presented in this paper has potential applications to fabricate other metal tungstates (MWO4) materials.

Published: July 2012

AbstractThe BaY2F8 crystals doped with different concentrations of Tm3+ ions were prepared by the temperature gradient technique (TGT). X‐ray powder diffraction was applied to analyze the phase. The cracking phenomenon along (010) and (100) planes of the crystals grown by temperature gradient technique was studied on the basis of the structure of BaY2F8 crystals. The absorption spectra were measured and investigated in the ultraviolet‐visible and near‐infrared ranges at room temperature. Several characteristic absorption bands of Tm3+‐doped BaY2F8 crystal were observed. The emission and excitation spectra were obtained and investigated at room temperature and 12 K, showing the characteristic emission peaks of Tm3+ ions. The temperature dependence of Photoluminescence curve was also investigated in the range of 12–296 K. The luminescence intensity of emission bands decreased with increasing temperature, while the effective bandwidth increased. The up‐conversion spectrum excited at 650 nm was recorded and up‐conversion mechanism was analyzed in detail. The result showed the purple, green and yellow emissions corresponding to 3P1→3F3, 1D2→3H5 and 3P0→1G4 transitions, respectively.

AbstractCobalt Ferrite (CoFe2O4) nanorods and nanorings have been successfully controllable synthesized by solvothermal method. The specific characteristics were confirmed by X‐ray diffraction studies (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). The measurement of their electrochemical properties as supercapacitor electrode materials indicate different morphological characterizations have various capacitive effects, and CoFe2O4 nanorings generally have larger specific capacitances than nanorods at different scan rates and current densities in 1.0 M KOH solution.

AbstractReactions exchanging the cation in (nBu4N)[Ni(dmit)2] to cis‐cyclohexane‐1,4‐diammonium (cis‐CHDA) in the presence of [18]crown‐6, benzo[18]crown‐6 (B[18]crown‐6) and dibenzo[18]crown‐6 (DB[18]crown‐6) yielded crystals of the monovalent [Ni(dmit)2] complex, namely (cis‐CHDA)([18]crown‐6)2[Ni(dmit)2]2 (1), (cis‐CHDA)(B[18]crown‐6)2[Ni(dmit)2]2 (2) and (cis‐CHDA)(DB[18]crown‐6)2[Ni(dmit)2]2 (3). The two ammonium groups (–NH3+) of the cis‐CHDA dication at axial and equatorial positions interact with oxygen atoms of the corresponding upper and lower crown ethers to form sandwich‐type supramolecular cationic structures. The lateral [Ni(dmit)2]− anion arrangements through S–S contacts along the short and long axis of [Ni(dmit)2] anions were realised in crystals of 1, 2, and 3 by the asymmetrical cis‐CHDA dication. The temperature‐ and frequency‐dependent anisotropic dielectric constants of a crystal of 1 were evaluated along the a, b and c axes, where the thermally activated motion of the structurally flexible cis‐CHDA dication was consistent with the dielectric responses.

Published: July 2012

AbstractOxidovanadium(IV) complexes [VO(pyphen)(L)]Cl2 (1, 2) and [VO(pydppz)(L)]Cl2 (3, 4), where L is 1,10‐phenanthroline (phen in 1 and 3) and dipyrido[3,2‐a:2′,3′‐c]phenazine (dppz in 2 and 4) are prepared and characterized. The crystal structure of [VO(pyphen)(phen)](ClO4)2 (1a) shows a six‐coordinate VN5O geometry with a VO2+ moiety in which the polypyridyl ligand binds in a meridional fashion and the phen ligand displays a chelating binding mode with an N‐donor site trans to the oxidovanadyl group. The complexes show a d–d band within 720–750 nm in DMF. The one‐electron paramagnetic complexes are 1:2 electrolytes in DMF. The complexes exhibit an irreversible VIV/VIII redox response near –0.85 V vs. SCE in DMF/0.1 M TBAP. The complexes bind to calf thymus (ct) DNA giving Kb values within 7.5 × 104 to 1.1 × 106 M–1. The complexes show poor chemical nuclease activity in the dark and exhibit significant DNA‐photocleaving activity in near‐IR light of 705 and 785 nm forming ·OH radicals. Complexes 2–4 show remarkable photocytotoxicity in HeLa cancer cells. FACS analysis of the HeLa cells treated with complex 4 shows cell death as highlighted by the sub G1 peak. Propidium iodide staining data indicate apoptosis as the primary mode of cell death.
