	Abstract:In the present work, fluoride doped tin oxide (FTO) as an interlayer was introduced into nickel and antimony co-doped tin dioxide (NATO) coated titanium electrodes to investigate the influence of FTO interlayer on the structural properties and lifetime performance of the electrodes. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques were used to characterize the morphology and crystal structure of the electrodes with or without FTO interlayer. The electrode surface became smoother with FTO interlayer introduced while the crystallite size reduced. Electrochemical impedance spectroscopy (EIS) was also adopted to analyze the electrodes' electrochemical behavior. With FTO interlayer introduced, the formation of titanium dioxide insulating layer on the titanium substrate was significantly retarded during the anodic process. The accelerated lifetime tests presented that the lifetime of the electrodes with proper FTO interlayer was 6 times longer than that without FTO interlayer. The mechanisms for the electrodes' lifetime enhancement with FTO interlayer were discussed.

	Abstract:Nano-ZnO-CeO2 coupled semiconductor was added into the chitosan(CS) anion exchange membrane layer to prepare the PVA-CMC/nano-ZnO-CeO2-CS (here, PVA: polyvinyl alcohol; CMC: carboxymethyl cellulose) bipolar membrane(BPM), and the prepared BPM was characterized by SEM, J-V characteristics, electronic universal testing machine, contact angle measurement and so on. Experimental results showed that nano-ZnO-CeO2 exhibited better photocatalytic property for water splitting at the interlayer of BPM than nano-ZnO or nano-CeO2, which could greatly reduce the membrane impedance of the BPM. Under the irradiation of high-pressure mercury lamps, the cell voltage of PVA-CMC/ nano-ZnO-CeO2-CS BPM decreased by 0.7V at the current density of 60mA/cm2, and the cell voltages of PVA-CMC/ nano-ZnO-CS BPM and PVA-CMC/ nano-CeO2-CS BPM were only reduced by 0.3V and 0.5V, respectively. Furthermore, the hydrophilicity, and mechanical properties of the modified BPM were increased.)

	Abstract:In this paper, a photo-responsive molecularly imprinted organic-inorganic hybrid sol-gel material was prepared by covalent imprinting of the template (ibuprofen) - functional monomer (4-hydroxyl-4′-[(Triisopropoxysilyl)propyloxy] azobenzene) for the specific binding of ibuprofen. After imprinting, ibuprofen was removed via hydrolysis in acid. The new molecularly imprinted organic-inorganic hybrid sol-gel material was found to behavior similarly to the organic polymer based photo-responsive molecularly imprinted polymer (MIP). The favorable binding strength of the imprinted receptor sites in the MIP for ibuprofen was found to be 2.28 x 103 M-1. Density of receptor sites in the MIP material was 4.0 ?mol/g-MIP. The release and uptake of ibuprofen from THF solution by the material could be reversibly photo-regulated upon alternate irradiation at 365 and 440 nm, respectively.

	Abstract:A series of bimodal porous CexZr1-xO2 (x = 0.2, 0.3, 0.4, 0.5, 0.6, 0.8, 1.0) solid solutions were prepared by complex-decomposition method. The results of XRD, Raman, SEM, mercury porosimetry and N2 adsorption/ desorption measurements indicated that the physical properties of the solid solutions were significantly affected by the Ce/Zr molar ratio and the calcination temperatures. The Ce0.5Zr0.5O2 solid solutions presented bimodal mesopores with narrow pore size distributions (PSD). These solid solutions can be used in dimethyl carbonate (DMC) synthesis from methanol and CO2. Results indicated that calcination temperatures and the molar ratio of CexZr1-xO2 were the key factor in determining the catalytic activity for DMC synthesis. It exhibited higher catalytic performance to DMC when the molar ratio of Ce to Zr is to be of 1.0 under the calcination temperature of 1273 K. However, the methanol conversion is still low which is limited by the reaction equilibrium. The addition of 1, 1, 1-trimethoxy methane (TMM) was engaged to consume H2O produced in synthesis of DMC, and found that it was very effective for the increase in the methanol conversion from 1.8 to 7.85% under 377 K, 20 MPa and 24 h. The combination of the bimodal porous catalyst with an effective H2O removal agent for the reaction system can provide a novel process of selective DMC production directly from CO2 and CH3OH with dramatic efficiency for the maximum CH3OH conversion of 10.4%. The mechanism of the direct synthesis of DMC from CO2 and CH3OH with the additive of TMM over CexZr1-xO2 catalyst was also discussed.

	Abstract:The hydrogen-bonded complexes of water with eight amino acids (Pro, Hyp, Ser, Glu, Arg, Lys, Gly and Asp) found frequently in collagen were studied. The structures, stability and vibrational spectra of the hydrogen-bonded complexes have been studied by using DFT calculations. Full geometry optimization has been performed for the studied complexes by B3LYP/6-31+G(d) and B3LYP/6-311++G(d,p) calculations. The optimized geometric parameters and interaction energies for various complexes at two levels were estimated. Finally, the vibrational spectra of these complexes were also investigated. Having in mind the hydrogen bonds formed by C=O and N–H groups of the backbone and polar amino acid side chains in collagen, the hydrogen-bonded complexes can be ordered according to their stability as follows: Arg > Glu > Ser > Asp > Pro > Lys > Hyp > Gly. The BSSE corrected interaction energies suggest that the interactions of Pro, Lys, Hyp and Gly with water are similar. The B3LYP/6-311++G(d,p) calculations show the frequency red-shift in hydrogen bond donor modes and an increase of the IR intensity of the νOH vibration of H2O in the complexes A4, G3, N4, P2, L3, Hp4, Gly1 and S3 beyond thirty times.

	Abstract:Kinetics and mechanism of the electrochemical oxidation of thiocyanate on a Pt electrode were investigated using various electrochemical methods, in which both current and potential oscillations have been observed. Cyclic voltammetry measurements illustrate that the oxidation process is through two steps. In addition to the oscillatory behavior, the system also exhibits bistability, in which the oxidation could be switched between a high and low current density states with a temporal potential perturbation. The presence of inert ions with stronger absorption also induces transitions from oscillatory to steady reactions in the thiocyanate system.

	Abstract:Photonic supraparticles were sassembled by growing colloidal crystals in aqueous droplets suspended in n-butanol. The droplet products were highly ordered and smooth particle assemblies, which diffract light and have remarkable structural stability. The method allows control of particle size and shape from spheres through balls to toroids. The results provide the way to controllable formation of a wide variety of photonic supraparticles.
