  • Linear and Nonlinear Optical Properties of Novel Multi-branched Oligomers
    • Authors: Li-jing Gong; Ying-hui Wang, Zhi-hui Kang, Tian-hao Huang, Ran Lu Han-zhuang Zhang
      First page: 636
      Abstract: We investigate the fluorene-vinylene unit dependent photo-physical properties of multi-branched truxene based oligomers (Tr-OFV n , n =1–4) employing steady-state absorption and emission spectroscopy, transient absorption spectroscopy, two-photon fluorescence, and z-scan technique. The results show that the increasing of fluorene-vinylene unit leads to a red-shift in the spectra of absorption and fluorescence, and shortens the excited state lifetime. Meanwhile, two-photon fluorescence efficiency and two-photon absorption cross section of truxene based oligomers gradually enhance in company with the extension of π-conjugated length. In addition, the values of two-photon absorption cross section modeled on the sum-over-state approach agree well with the experimental ones. The results indicate multi-branched truxene based oligomers bearing oligo(fluorene-vinylene) arms are promising organic materials for two-photon applications.

  • Softening of C—H Symmetric Stretching Vibrational Modes for CH 2 and
           CH 3 Radicals Adsorbed on Cu n ( n =1–6) Clusters
    • Authors: Xi-hui Cheng; Da-jun Ding, Yong-gang Yu Ming-xing Jin
      First page: 649
      Abstract: The properties of C—H vibration softening for CH 2 and CH 3 radicals absorbed on Cu n ( n =1–6) clusters have been investigated, using the density functional theory with hybrid functional. The results indicate that the absorption of CH 2 on Cu clusters is stronger than the case of CH 3 . The vibrational frequencies of C—H bonding agree with the experimental results obtained for CH 2 and CH 3 absorbed on Cu(111). With the increase of cluster size, the softening (Einstein shift) of C—H vibrational modes become stronger.

  • Protonation Effect on One- and Two-photon Absorption Property of a Newly
           Synthesized Octupolar Chromophore
    • Authors: Hong-juan Ding; Jie Sun Chuan-kui Wang
      First page: 666
      Abstract: The protonation effects on one- and two-photon absorption properties of an octupolar molecule TA with 1,3,5-triazine core and pyrrole electron-donating end-groups have been studied at hybrid density functional theory level. A computational scheme is developed to simulate a proton attached to an atom. The numerical results show that large changes in both one- and two-photon absorption properties are observed when the compound is transformed from neutral to threefold protonated states. When the compound is protonated, more charge transfer states appear and the absorption band has a red-shift. Furthermore, the two-photon absorption cross-section is largely enhanced. The theoretical calculations demonstrate the protonation effect on promoting the intramolecular charge transfer strength. The results present qualitative agreement with the experimental observations. A two-photon absorption switch with the compound TA based on the protonation effect is proposed.

  • First Principles Study on Encapsulation of Alkali Metals into ZnO Nanocage
    • Authors: Mohammad T. Baei; Ali Ahmadi Peyghan Zargham Bagheri
      First page: 671
      Abstract: Encapsulation of alkali metals (Li, Na, K, and Rb) into Zn 12 O 12 nanocage has been investigated using density functional theory. Encapsulation of Li and Na atoms is found to be thermodynamically favorable at 298 K and 100 kPa, with negative Gibbs free energy change Δ G of about −130.12 and −68.43 kJ/mol, respectively. By increasing the size of encapsulated atom the process become less favorable so that in the cases of K and Rb encapsulations the Δ G values are positive. The results indicate that the LUMO, Fermi level, and specially HOMO of the cluster are shifted to higher energies so that the HOMO-LUMO gap of the cluster is significantly narrowed in all the cases. After encapsulation of the alkali metals the work function of cluster is decreased due to the shift of the Fermi level to higher energies. Therefore, the emitted electron current density from the Zn 12 O 12 cluster will be increased.

  • Feature Designed Growth of 3D Flower-like SiO 2 Growing on
           Polyethyleneimine Modified CaCO 3 Microparticles
    • Authors: Xin-mei Zheng; Yan-xing Qi Gong-xuan Lu
      First page: 687
      Abstract: We report on the ability to create complex 3D flower-like SiO 2 in vitro via CaCO 3 microparicles supported by polyethyleneimine mediated biosilicification under experimentally altered chemical influences. The morphology, structure, composition of the product have been investigated with the X-ray photoelectron spectrum, scanning electron microscope, transmission electron microscope, and energy-dispersive spectroscopy. The overall morphologies could be controlled to shift from a characteristic network of flower-like silica sphere to a sheet-like structure by adjusting physical adsorption of different amount of polyethyleneimine onto the surface of the CaCO 3 microparticles.

  • Interaction of Egg-Sphingomyelin with DOPC in Langmuir Monolayers
    • Authors: Chang-chun Hao; Run-guang Sun Jing Zhang
      First page: 691
      Abstract: Lipid rafts are a dynamic microdomain structure found in recent years, enriched in sphingolipids, cholesterol and particular proteins. The change of structure and function of lipid rafts could result in many diseases. In this work, the monolayer miscibility behavior of mixed systems of Egg-Sphingomyelin (ESM) 1 with 2-dioleoyl-sn-glycero-3-phosphocholine was investigated in terms of mean surface area per molecule and excess molecular area Δ A ex at certain surface pressure, surface pressure and excess surface pressure Δπ ex at certain mean molecular area. The stability and compressibility of the mixed monolayers was assessed by the parameters of surface excess Gibbs free energy Δ G ex , excess Helmholtz energy Δ H ex and elasticity. Thermodynamic analysis indicates Δ A ex and Δπ ex in the binary systems with positive deviations from the ideal behavior, sug...

           4 ) 3 Solid Electrolyte Prepared by 1,2-Propylene glycol-assisted
           Sol-gel Method
    • Authors: Lin-chao Zhang; Peng Chen, Zhang Hu Chun-hua Chen

      Abstract: Lithium-ion conductor Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 with an ultrapure NASICON-type phase is synthesized by a 1,2-propylene glycol (1,2-PG)-assisted sol-gel method and characterized by differential thermal analysis-thermo gravimetric analysis, X-ray diffraction, scanning electron microscopy, electrochemical impedance spectroscopy, and chronoamperometry test. Due to the use of 1,2-PG, a homogeneous and light yellow transparent precursor solution is obtained without the precipitation of Ti 4+ and Al 3+ with PO 4 3− . Well crystallized Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 can be prepared at much lower temperatures from 850 °C to 950 °C within a shorter synthesis time compared with that prepared at a temperature above 1000 °C by a conventional solid-state reaction method. The lithium ionic conductivity of the sintered pellets is up to 0.3 mS/cm at 50 °C with a...

  • Melamine/Stearic Acid Composite Nanowires and Vesicles with an
           Intercalated Nanostructure Prepared through NCCM Method
    • Authors: Juan Guo; Dao-yong Chen
      First page: 708
      Abstract: A solvent-non-solvent method invented in our laboratory for preparing non-covalently connected micelles (NCCM) was used to intercalate melamine (MA) molecules into stearic acid (SA) bilayers to form the composite nanoparticles with an intercalated nanostructure in which a melamine bilayer is sandwiched between two stearic acid bilayers, NCCM method helps to sufficiently mix the two components in nanospace and meanwhile inhibits the strong tendency of self-crystallization of MA, leading to the intercalation. Although the nanoparticles have a regular inner structure, the primary MA/SA nanoparticles have an irregular morphology. Regular nanoparticles were obtained through annealing the suspension of the primary nanoparticles. Through annealing at different temperatures, the MA/SA composite nanowires and vesicles with an intercalated structure were prepared respectively. It is proposed that the morphological change results from the change in the intercalated structure.

  • Growth and Electronic Properties of Ag Nanoparticles on Reduced CeO
           2− x (111) Films
    • Authors: Dan-dan Kong; Yong-he Pan, Guo-dong Wang, Hai-bin Pan Jun-fa Zhu
      First page: 713
      Abstract: Ag nanoparticles grown on reduced CeO 2− x thin films have been studied by X-ray photoelectron spectroscopy and resonant photoelectron spectroscopy of the valence band to understand the effect of oxygen vacancies in the CeO 2− x thin films on the growth and interfacial electronic properties of Ag. Ag grows as three-dimensional particles on the CeO 2− x (111) surface at 300 K. Compared to the fully oxidized ceria substrate surface, Ag favors the growth of smaller particles with a larger particle density on the reduced ceria substrate surface, which can be attributed to the nucleation of Ag on oxygen vacancies. The binding energy of Ag3d increases when the Ag particle size decreases, which is mainly attributed to the final-state screening. The interfacial interaction between Ag and CeO 2− x (111) is weak. The resonant enhancement of the 4f level of Ce 3+ species in RPES indicates a partial Ce 4+ →Ce

           in Huaibei Area, China
    • Authors: Su-wen Li; Pin-hua Xie, En-hua Jiang, Yong Zhang Hai-feng Dai
      First page: 739
      Abstract: Huaibei is an energy city. Coal as the primary energy consumption brings a large number of regional pollution in Huaibei area. Differential optical absorption spectroscopy (DOAS) as optical remote sensing technology has been applied to monitor regional average concentrations and inventory of nitrogen dioxide, sulfur dioxide and ozone. DOAS system was set up and applied to monitor the main air pollutants in Huaibei area. Monitoring data were obtained from 7 to 28 August, 2011. Monitoring results show measurements in controlling pollution are effective, and emissions of pollutants are up to the national standard in Huaibei area. Prediction model was also created to track changing trend of pollutions. These will provide raw data support for effective evaluation of environmental quality in Huaibei area.
