Jie Zhang, Xiaoshu Zhu, Heyong Huang, Yinping Zhang
Advances in Chemical Engineering and Science (ACES) , 2017, DOI: 10.4236/aces.2017.72017
Abstract: BaWO4 nanorods have been successfully synthesized in w/o microemulsion system containing barium ions via a simple reaction between Ba2+ and \"\" . The BaWO4 Nanorods were characterized by XRD, TEM, and SEM, respectively. Results showed that the solvents composition—volume ratio of 4-dioxane and distilled water—played the key role in the formation of BaWO4 Nanorods. Furthermore, the strong vibration at 925 cm1 on its Raman spectrum indicated that the BaWO4 nanorods is good at stimulating Raman scattering in transient and steady-state, making it as a promising candidate material for laser with self-raman conversion of radiation inside the active medium.

International Journal of Photoenergy , 2010, DOI: 10.1155/2010/547135
Abstract: The interaction of Zn(II) porphyrin (ZnPP) with colloidal TiO2 was studied by absorption and fluorescence spectroscopy. The fluorescence emission of ZnPP was quenched by colloidal TiO2 upon excitation of its absorption band. The quenching rate constant ( ) is ?M?1?s?1. These data indicate that there is an interaction between ZnPP and colloidal TiO2 nanoparticle surface. The quenching mechanism is discussed on the basis of the quenching rate constant as well as the reduction potential of the colloidal TiO2. And the mechanism of electron transfer has been confirmed by the calculation of free energy change by applying Rehm-Weller equation as well as energy level diagram. 1. Introduction Wide-band gap semiconductor particles such as TiO2 have been widely used for different applications in photocatalysis and the environment [1, 2].Over the past decades, considerable interest has been shown in the modification of TiO2 semiconductors by organic dyes to extend the photoresponse to visible light owing to their potential application in solar energy conversion [3–5]. Dye sensitization is considered to be an efficient method to modify the photo response properties of TiO2 particles. The dyes used are erythrosine B [6], rose Bengal [7], metal porphyrin [8–10], and so forth. Porphyrins, (including metal-free porphyrins, metalloporphyrins and supramolecular porphyrins) [11] are recognized to be the most promising sensitizers [12]. The chemistry of porphyrin derivatives has played an important role especially during the past decade in particular branches of new materials science, and many researchers have undertaken projects on the synthesis of variously substituted compounds to obtain new functional materials [13–15]. Metalloporphyrin may be an appropriate candidate because of its high absorption coefficient within the solar spectrum and its good chemical stability in comparison to that of other dyes. They are highly effective photocatalysts due to their very strong absorption in the 400?nm–450?nm region (Soret band) and in the 500?nm–700?nm region (Q-bands) and, in fact, the presence of p-electrons affords the condition for electron transfer during the photoreaction. In the present work we have investigated the electron transfer from excited ZnPP (see Scheme 1) to the conduction band of TiO2 colloid by using absorption and fluorescence spectroscopy. Scheme 1: Structure of ZnPP. 2. Materials and Methods 2.1. Materials Zn(II) porphyrin and tetrabutyl titanate were purchased from Aldrich. The doubly distilled water was used for preparing the solutions. All measurements

Materials , 2010, DOI: 10.3390/ma3020764
Abstract: Mesoporous silica molecular sieves are a kind of unique catalyst support due to their large pore size and high surface area. Several methods have been developed to immobilize heteropolyacids (HPAs) inside the channels of these mesoporous silicas. The mesoporous silica-supported HPA materials have been widely used as recyclable catalysts in heterogeneous systems. They have shown high catalytic activities and shape selectivities in some reactions, compared to the parent HPAs in homogeneous systems. This review summarizes recent progress in the field of mesoporous silica-supported HPAs applied in the heterogeneous catalysis area and preparation of nanostructured metal oxides using HPAs as precursors and mesoporous silicas as hard templates.
CO2 gas emplacement age in the Songliao Basin: Insight from volcanic quartz 40Ar-39Ar stepwise crushing

Abstract: Due to a lack of suitable minerals, the gas/oil emplacement ages have never been accurately obtained before. CH4-CO2-saline-bearing secondary inclusions are found in quartz from the volcanic rocks of the Yingcheng Formation, the container rocks of the deep CO2 gas reservoir in the Songliao Basin. The inclusion fluid was trapped into microcracks in quartz during the gas emplacement and accumulation, providing an optimal target for the 40Ar-39Ar stepwise crushing technique to determine the CO2 gas emplacement age. 40Ar-39Ar dating results of a quartz sample by stepwise crushing yield a highly linear-regression isochron with an age of 78.4±1.3 Ma, indicating that the accumulation of the deep CO2 gas reservoir in the Songliao Basin occurred in the late Cretaceous. This is the first time to report an exact isotopic age for a CO2 gas reservoir, which indicates that the 40Ar-39Ar dating can serve as a new technique to date the oil/gas emplacement ages.

Abstract: C. G Jung and his analytic psychology influenced the studies and theories of Chinese psychology, and even the humanities and social sciences in China. But Jung ' s psychology itself had an inside and deep relationship with Chinese culture. Jung himself absorbed the sources of Chinese cultural thought, that became the cornerstone of his analytic psychological systems. At the same time, Jung contributed in the spreading of Chinese culture in the western world. In this paper, through sinologist Richard Wilhelm, the book of The Secret Of Golden Flower, and through The Book Of Change and The Dao, the authors discussed the relationship between Jung 's analytic psychology and Chinese culture, elucidated the significance of the psychological thought in the Chinese cultural tradition.

Abstract: In traditional Chinese culture, I Ching has been called the "top of all classics", and "the origin of the Great Dao". Psychology historians today take China as the first homeland of psychology. Theyrealize that in traditional Chinese culture rich psychological thoughts and special psychological system are embraced. Therefore, we will take I Ching as the foundation, through analyzing the charater "heart"(Xin) in the I Ching, the meaning of the Chinese character heart in the Great Commentaries, and the symbolic meaning of heart in the hexagrams, to elaborate the meaning of Chinese Cultural Psychology,and its influence to contemporary Westem psychology.

Abstract: Background and objective It has been proven that epithelial-mesenchymal transition (EMT) not only correlated with embryonic development but also could promote tumor invasion and metastasis. Transforming growth factor beta-1 (TGF-β1) has been identified as the main inducer of tumor EMT. The aim of this study was to investigate the effects of TGF-β1 on EMT and PI3K/AKT signaling pathway in lung adencarcinoma PC9 cells. Methods Cultured PC9 cells were treated with different concentrations of TGF-β1 for 48 h. The morphological changes were observed under phase-contrast microscopy; EMT relative marker protein changes were assessed by Western blot and immunoflurescence staining. In addition, the expression of AKT and P-AKT were also measured by Western blot. Results The data showed that TGF-β1 could induce PC9 morphological alteration from epithelial to mesenchymal and upregulate the expression of mesenchymal maker protein Fibronectin. Obviously, the expression of P-AKT was downregulated by TGF-β1 treatment for 48 h. Conclusion TGF-β1 might induce EMT of PC9 cells , accompanied by the changes of PI3K/AKT signaling pathway.
