Authors: Zhang X. H. , Jia C. , Chen Y. Q. , Su Y. , Zhou H. Y. 
Published: May 2015

AbstractThe authors developed a simple solvothermal route to synthesis of PbS nanocrystals in the mild binary mixed solvent made of diethylenetriamine (DETA) and water. Two kinds of PbS nanostructures (dice‐like and cubic) have been successfully synthesized in the binary mixed solvothermal system at 150 °C by changing the sulfur source. The products were characterized by X‐ray diffraction (XRD), field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). The results show that the as‐prepared dice‐like PbS crystals have a hole on each of their faces. To elucidate the relationship between reaction systems and the morphologies of the final products, the authors also investigated the crystal growth by using different sulfur source. Based on the experimental results, the possible growth mechanism of the dice‐like PbS crystals was proposed.

Authors: Bhatti Haq Nawaz , Samin Ghufrana , Hanif Muhammad Asif 
Published: May 2015

AbstractThis study investigated the feasibility of Fusarium solani biomass as a biosorbent for Cu(II) and Pb(II) removal from aqueous solutions. Batch sorption experiments were carried out for Cu(II) and Pb(II) to quantify the sorption kinetics, pH, biosorbent dose and pretreatment of F. solani biomass. Biomass metal uptake clearly competed with protons present in the aqueous medium, making pH an important variable in the process. The maximum biosorption by F. solani biomass was obtained with solutions having pH 5 for both metal ions. An enhanced Cu(II) removal (96.53%) was observed for aluminum hydroxide pretreated biomass. Maximum Pb(II) removal (95.48%) was observed with native biomass. Time dependence experiments for the metal ions uptake showed that adsorption equilibrium reached almost 240 min after metal addition. The kinetic studies showed that the biosorption process followed the pseudo second‐order rate model for Cu(II) and Pb(II). The equilibrium data fitted well to the Langmiur isotherm model.

FT‐IR Studies of Plasticization of Propylene Carbonate and Ethylene Carbonate in PEO‐NaSCN Polymer Electrolytes
Authors: Zhang Hu‐Cheng , Wang Jian‐Ji 
Published: May 2015

AbstractThe FT‐IR spectra of poly(ethylene oxide) (PEO)‐based gel polymer electrolytes (GPEs), PEO‐NaSCN‐propylene carbonate (PC) and PEO‐NaSCN‐ethylene carbonate (EC), were measured at room temperature. Along with the FT‐IR spectra of NaSCN‐PC, PEO‐PC, and PEO‐EC, the interactions in the GPEs and the plasticizations of PC and EC are revealed. It is shown that the coordination of ether oxygen in PEO with NaSCN is the preferential solvation, whereas the interactions of PC and EC with NaSCN are relatively weak in the GPEs. However, both PC and EC play an important role in inhibiting the formation of crystalline complexes and high ionic aggregations, in addition to the ability of transformation of PEO from crystal to amorphism. It is further observed that EC exhibits the stronger ability to transform PEO crystalline into amorphism than PC when the plasticizer content in PEO is more than 25%, and also the far stronger ability to decompose the crystalline complexes, in particular, in polymer electrolytes with high salt content.

Substitute Effect on the Structure, Stability of Valence Isomers and Aromaticity of 1‐H‐Boratabenzene
Authors: Ghiasi Reza , Yadegari Neda 
Published: May 2015

AbstractDensity functional theory (B3LYP) calculations were performed on the Me and F substituted valence isomeric forms of 1‐H‐boratabenzene. The calculations revealed that the planar benzene analog is the lowest energy isomer. Its aromaticity is analyzed in the light of the nucleus‐independent chemical shift (NICS) and shows that aromaticity increases in F substituted, but decreases in Me substituted. These calculations indicate substitution of BH with BMe and BF doesn't cause significant variation in bond length.

Study on Determination of Triterpenoids in Chaenomeles by High Performance Liquid Chromatography and Sample Preparation with Matrix Solid Phase Dispersion
Authors: Li Yin‐Ke , Fan Peng , Xu Yi‐Ran , Huang Yun , Hu Qiu‐Fen 
Published: May 2015

AbstractA new method for the simultaneous determination of the major triterpenoids in Chaenomeles (Chinese medicinal herb) by high performance liquid chromatography (HPLC) and sample preparation with matrix solid phase dispersion (MSPD) was developed. A 0.1 g of sample was placed into an agate mortar and gently blended with 0.4 g silica gel to obtain a homogeneous mixture. This mixture was introduced into a Teflon cartridge, and the triterpenoids fraction was eluted from the cartridge with dichloromethane‐acetone (85:15). The residue was dissolved with methanol after the evaporation of the solvent (dichloromethane and acetone). The triterpenoids were separated on a ZORBAX Stable Bound (4.6 mm × 100 mm, 1.8 μm) C18 column by gradient elution with acetonitrile and water as the mobile phase and detected with evaporative light scattering detection. This method provides good reproducibility and sensitivity for the quantification of seven major triterpenoids, namely erythodiol, betulin, acetyl ursolic acid, ursolic acid, oleanolic acid, betulinic acid, pomolic acid, respectively. The relative standard derivations of overall intra‐day variations were less than 2.0%, and the relative standard derivations of inter‐day variations were less than 2.5%. The standard recoveries (three different concentrations of markers: 0.1, 0.5 and 2.0 mg) ranged from 97‐103%. The results demonstrate that this method is simple, sensitive, selective, and suitable for the quality control of this commonly used Chinese medicinal herb.

A 3D‐QSAR Study of Celebrex‐Based Pdk1 Inhibitors Using Comfa Method
Authors: Wang Wen‐Hung , Jena N. R. , Wang Yi‐Ching , Sun Ying‐Chieh 
Published: May 2015

AbstractA 3D‐QSAR study of celebrex‐based compounds of PDK1 inhibitors using comparative molecular field analysis (CoMFA) was carried out. The structures of the compounds were obtained using quantum chemistry calculation. CoMFA calculations for a number of grouped subsets of compounds gave q2 values of correlation in the range from 0 to 0.8. The low q2 values should be mainly due to the narrow span of biological activity. Calculations for several subsets of 11–13 compounds gave high q2 values, with 0.5–0.8. Factors affecting the results of the calculations are discussed. Calculated results with high q2 values suggest that further chemical modifications of the compounds could lead to enhanced activity and could be an aid in the design of celebrex‐based cancer drugs.

Authors: Lu Cheng‐Chi , Su Shuenn‐Kung 
Published: May 2015

AbstractA new gelator of urea‐containing triazine derivatives was synthesized and tested in order to explore the gelation potential in different organic solvents. This compound has been found to form organogels with a variety of organic solvents such as decalin and other solvents. The resulting thermo‐reversible gel was characterized by using the dropping ball method and a number of other instruments. The melting temperature of the gel increased with the gel concentration. The intermolecular hydrogen bonding of gelation was demonstrated through an FT‐IR spectrometer. UV‐Vis and fluorescence analysis showed that the gel displayed various optical effects in different organic solvents. The blue fluorescence of the gel in decalin and the quenched effect of gel in CHCl3 were displayed, respectively. Morphological features in decalin and CHCl3 were studied by applying atomic force microscopy (AFM), and the morphological features demonstrated that there were different aggregations in different solvents. In conductivity electrolyte experiments, the organogel electrolytes indicated high conductivity (σ) comparable to the corresponding NaClO4/THF solution. The conductivity of gel electrolytes was increased with electrolyte salt.

Published: May 2015

AbstractBamboo charcoal supporting silver (BC/Ag) was prepared by activation and chemical reduction. The BC/Ag composites were characterized by silver particle size and distribution, silver ion (Ag+) release and antibacterial properties. Scanning and transmission electron microscopy (SEM and TEM) showed that the Ag particles were distributed uniformly on the BC matrix. The Ag particle size was found to be less than 150 nm based on TEM. The Ag+ release increased initially which was followed by a marginal increase between the 8th and 24th hour. Composites contained higher amounts of silver exhibited a further rise in Ag+ release from the 24‐hours of storage in water. The antibacterial effects of the BC/Ag composite powders against Pseudomonas aeruginosa and Staphylococcus aureus were assessed from the minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) method, and an excellent antibacterial performance was discovered.

Surface Modifications and Optoelectronic Characterization of TiO2‐Nanoparticles: Design of New Photo‐Electronic Materials
Authors: Yoon Min‐Joong 
Published: May 2015

AbstractTiO2 nanoparticles are of great current interest for applications in photo‐electronic materials including light‐energy conversion, artificial photosynthetic systems as well as photocatalysis. The success of these applications relies on the exciton recombination dynamics and visible‐light sensitivity of the TiO2 nanomaterials. Thus, in order to develop the highly efficient photo‐electronic materials absorbing visible light, different low dimensional TiO2 nanostructures such as nanodiscs, nanofibers and nanochains were synthesized, and thereafter their surfaces were modified by incorporating with Sn‐porphyrins and heteropoly acid. The optoelectronic properties of the surface‐modified nanomaterials were investigated with regard to the optical properties and the surface exciton dynamics by using both steady‐state and ultrafast time‐resolved laser spectroscopic techniques including single nanoparticle photoluminescence technique. These results were correlated with the photo‐electronic properties including photocatalytic activities and solar cell efficiencies, indicating that the electron transfer mechanism in the modified nanostructures may be similar to the “Z‐scheme” of the plant photosynthetic system so that both photocatalytic activity and solar cell efficiencies were synergistically enhanced by using two color illumination.
Association Equilibrium of Methylene Blue by Spectral Titration and Chemometrics Analysis: A Thermodynamic Study
Authors: Ghasemi Jahan B. , Miladi M. 
Published: May 2015

AbstractThe monomer‐dimer equilibrium of methylene blue (MB, Scheme I) has been investigated by means of UV‐Visible spectroscopy in aqueous solutions. The self aggregation of MB in water has been investigated by recording absorption spectra in the wavelength range of 450–750 nm, and in different ionic strengths using concentrated KCl solutions in the temperature range of 20–90°C. Chemometrics analysis of the spectral data gave a dimerization constant, individual spectra of the monomer and dimer forms of the dye molecule. The quantitative analysis of the data of the undefined mixture was carried out by simultaneous resolution of the overlapping spectral bands in the whole set of absorption spectra. The dimerization constants of MB determined by mathematical deconvolution of the thermometric spectral titration data show dependency on temperature variations. The concentration range of MB was 6.00 × 10−5‐3.00 × 10−4 M. Utilizing the van't Hoff relation, which describes the dependence of the equilibrium constant on temperature, the thermodynamics parameters ΔH° and ΔS° of the aggregation process were determined. The compensation effect was verified by the thermodynamics results of the dimerization process of the dye.
