An interesting route was developed for symmetrical structures of the silver phosphate (Ag3PO4) crystal with gyro shape. The Ag 3PO4 crystal belongs to the cubic crystal system and revealed a screw dislocation in the {100} facets with helical growth along the epitaxial spin axis. In this reaction system, the acrylamide (AM) polymer monomer was used as a cooperation reagent. The Ag3PO4 crystal exhibits photooxidative capabilities for the polymerization to form polyacrylamide (PAM) under visible-light irradiation, and the energy released during this polymerization overcomes the surface energy required for creating screw dislocation forming hexagonal spin axes in three dimensions spontaneously. The investigated mechanism confirmed the driven role of dynamic-template, and the explored Ag3PO4 crystal control method could be used to synthesize other inorganic crystals. © 2013 American Chemical Society.

An unusual copper(ii) coordination polymer {[Cu(tmtz)(H2O) 4][Cu2(tmtz)2(sip)2]·4H 2O}n (1) (tmtz = 1,4-bis(1,2,4-triazol-1-ylmethyl)-2,3,4, 5-tetramethylbenzene, sip = 5-sulfoisophthalate) is synthesized by the hydrothermal reaction. X-Ray structural analysis shows that 1 is comprised of two distinct and crystallographically independent polymeric motifs polythreading together. The first motif of 1 is an unusual (3,5)-connected 3D anionic network [Cu2(tmtz)2(sip)2]. The second motif in 1 is the [Cu(tmtz)(H2O)4]n 1D cationic chain. A polythreading array formed by a (3,5)-connected 3D anionic network and 1D cationic chains. The catalytic performance exhibits that 1 is active as a catalyst for the degradation of methyl orange. The thermal analysis is also observed. This journal is © The Royal Society of Chemistry 2013. Source

In this paper, we introduce the Hermite polynomial's coherent state (HPCS) |α)H, which is defined as Hn(X)|α) up to a normalization constant and where Hn(X) is the coordinate operator's Hermite polynomial of order n and |α) = exp(-(1/2)|α|2 + aa†)|0). This state may be produced by the superposition of some different photon added coherent states when n = 2. The mathematical and physical properties of HPCS are also studied. It is shown that HPCS has remarkable nonclassical state features such as sub-Poissonian and squeezing properties. © 2012 Optical Society of America. Source

The carbon dot (C-ZnO NCs) modified zinc oxide with novel visible-light catalytic abilities was mass produced by combustion method. During the formation process, the generated gas of reagents under high temperature can effectively break the product into small particles. Meanwhile, a certain amount of carbon dots have been formed and loaded on the surface of ZnO NCs. The results suggest that the carbon dots have a huge impact on the photocatalytic performance. Specifically, when the molar ratio of glycine to zinc nitrate was 2:1, the product was a monodisperse particle with an average diameter of about 70-80 nm and BET specific surface area of 11.88 m2·g-1, which exhibited the best catalytic efficiency. The degradation process of Rh. B can be completed within 15 min, with an increase of 433.3% compared with pure ZnO materials (80 min). The present study is not only significant for improving large-scale production of modified ZnO NCs but also for suggesting practical application fields such as environmental catalysts. © 2015 American Chemical Society.

Symmetrical silver phosphate (Ag3PO4) crystals with porous structure were grown by a facile controllable route in aqueous solution. The Ag3PO4 crystals have a cubic-type structure and the morphologies are distinctive under different conditions. The crystals had high purity, were well-crystallized and were free of secondary phases by powder X-ray diffraction, IR, Raman spectra, scan electron microscopy (SEM), transmission electron microscopy (TEM), and selected area electron diffraction (SAED). It is interesting that the different crystal faces of the crystals have high physical-chemical-biological activity and large surface areas, so as to act as high activity micro-reactors (HAMs). The HAMs can effectively improve the photocatalytic activity and bacteriostatic activity of the Ag3PO 4 crystals. Furthermore, we proposed a possible growth mechanism and detailed morphology transformation process of Ag3PO4 crystals with different properties. This journal is © The Royal Society of Chemistry.
