  The flow characteristics of the ink on the ink fountain roller of offset printing machine is very important for the ink amount control and the ink amount control can determine the color quality of printing products. This study simulates first the ink flow of only one ink area using CFX fluid simulation software, then two situations are simulated to analyze how the ink area is affected by its adjacent ink areas on each side. In the first situation, the adjacent sides of the middle ink area have the same ink key opening size that is larger than that of the middle area. In the second situation, the adjacent sides of the middle ink area have different ink key opening size and each is smaller than that of the middle area. From the analysis it can be seen that, in the printing process, the pressure and speed and ink layer thickness of ink on the ink fountain roller are affected by the interaction between adjacent ink areas. Compared with previous work that is limited to analyze the ink flow characteristics of only one ink area, the study aims to analyze the ink flow characteristics under the interactional effect of adjacent ink areas. The research provides a reference to the mutual influence between ink areas in the actual printing process and it’s important for the printing color quality control and has a better application prospect.

  We have synthesized four coordination polymers with two different nitrogen containing organic ligands and different lanthanide metal ions, under hydrothermal condition. [lcubLn2(bpdc)3(H2O)2rcub]n (Ln = Dy (1), Sm (2)) (bpdc = 2,2-bipyridine-3,3-dicarboxylic acid) are isostructural, with 2-D supramolecular layer structure composed from 1-D chains. Like 1 and 2, [lcubLn(pzda)2(H2O)2rcub · 4H2O]n (Ln = Dy (3), Nd (4)) (pzda = pyrazine-2,6-dicarboxylic acid) are also isostructural with 1-D chain-like structures. The photoluminescence of 2 is studied.

  Five new coordination polymers synthesized from d10 metal ions, aliphatic carboxylic acids, and bidentate nitrogen ligands have been characterized with single crystallographic X-ray analysis, IR, and TG. Compound 1 has a twofold 3-D network. During the synthesis of 1, fumaric acid reacts with water giving malic acid, which coordinates Cd forming 2. If we use Zn instead of Cd, 1-D chain-like 3 is formed. With hydrogen bonds and π-π interactions, the 1-D covalent chains form a 3-D supramolecular network. The 3-D supramolecular networks connect together and form a twofold interpenetration structure. Compound 4 shows a 2-D layer structure. Compound 5 exhibits 1-D double-chain structure composed by hydrogen bonds. We studied the fluorescence of 1, 2, 3, and 5.
