Two new Co(II) coordination polymers have been synthesized under different pH values through hydrothermal reactions. Complex 1 exhibits a 3D polythreaded network based on 4-connected sql 2D layer. Complex 2 has a (4,4,5)-connected trinodal 3D pillar-layered network with a (42·64)2( 42·67·8)2( 64·82) topology. Weak antiferromagnetic couplings were observed in complexes 1 and 2.

Pure and indium doped antimony telluride (Sb2Te3) crystals were grown by the physical vapor deposition (PVD) method. Incorporation of indium atoms into the antimony sub lattice improved Seebeck coefficient and reduced thermal conductivity. The increased figure of merit, Z = 1.23x10-3K-1 for vapor grown Sb1.8In0.2Te3 platelets indicates that it could be used as a potential thermoelectric candidate.
- Isothermal crystallization behavior and crystal structure of poly(ethylene terephthalate-co-1,4-cyclohexylene dimethylene terephthalate) (P(ET/CT)) copolyesters

- The crystallization rate, crystallinity and transparency of these copolyesters during the same isothermal crystallization process decreased firstly and then increased remarkably with the increase of 1,4-CHDM content.
- The crystal structure changed from PET-type lattice to PCT-type lattice in intermediate composition.
- The small incorporation of 1,4-CHDM into PET could lead to the formation of larger spherulite crystals than that of PET. But small and grainy crystallites appeared with further increase in the 1,4-CHDM content.
- Surface-morphology evolution of ZnO nanostructures grown by hydrothermal method

Surface morphology evolution of ZnO nanostructures in hydrothermal process has been explored with various stirring time and ammonia contents, respectively. Experimental results shows that extension of stirring time of the precursor results in morphology transformation from star-like to wire-like ZnO nanocrystals, meanwhile, with increasing ammonia content, the morphology of ZnO crystals is transformed from irregular shape, hexagon sheets to nanorods.
- Self-assembly of a luminescent Zn(II) carboxylate with the diamondoid topology

The Cd(II) polymer crystallizes in the space group P212121 of orthorhombic crystal system and features a dense 4-connected 3D diamondoid topological framework. Moreover, the compound displays higher thermal stability and stronger luminescene.
