Two Co(II) coordination polymers, {[Co(bdc)(bib)(H2O)] ·H2O}n (1) and {[Co(bdc)(bibp)]}n (2), where H2bdc = 1,4-benzenedicarboxylic acid, bib = 1,4-bis(1-imidazolyl)benzene, and bibp = 4,4′-bis(imidazolyl)biphenyl, have been synthesized by solvothermal methods and characterized by IR spectra, element analyses, thermal analysis, powder X-ray diffraction, and single crystal X-ray diffraction. Complex 1 exhibits a 3-D pillared-layer framework, the ligands of bib and bdc link Co ions to generate a 2-D layer structure, which is further pillared by the bib, giving the final 3-D pillared-layer networks. The void in 1 induces the three-fold interpenetrating structure. Complex 2 features three-fold interpenetrating 3-D architecture, bdc and bibp both adopt a bidentate bridging coordination to link Co ions to afford right-and left-handed helical chains; these helices fuse together and form the 3-D framework. © 2014 Taylor & Francis.

Anti-Cancer Agents in Medicinal Chemistry | Year: 2014

In the search for new metal-based anticancer agents as effective candidates for cisplatin, a lot of strategies such as synthesis of cisplatin analogs, trans-platinum compounds and non-platinum metal complexes have been put forward in the last forty years. The concept of multinuclearity for improving the chemotherapeutic activity has been proven in multinuclear platinum complexes such as BBR3464, recently, the effective approach has been successfully transferred to ruthenium complexes. In this review, we highlighted the recent progress in multinuclear platinum complexes and ruthenium complexes as anticancer agents, and their novel DNA binding properties such as phosphate clamps, long range DNA cross links, bisintercalation, interduplex cross links and DNA-protein cross-links were summarized to shed light on the rational design of polynuclear complexes as anticancer agents. © 2014 Bentham Science Publishers.

This article addresses the flow shop scheduling problem to minimize the sum of the completion times. On the basis of the properties in job sequencing, the triangular shortest processing time (TSPT) first and dynamic triangular shortest processing time first heuristics are designed to solve the static and dynamic versions of this problem, respectively. Moreover, an improvement scheme is provided for these heuristics to enhance the quality of the original solutions. For further numerical evaluation of the heuristics, two new lower bounds with performance guarantees are presented for the two versions of the problem. At the end of the article, a series of numerical experiments is conducted to demonstrate the effectiveness of the algorithms. © 2013 Taylor & Francis Group, LLC.

Owing to noise in industrial environment, wireless signal is seriously interfered in industrial environment, and wireless communication quality will be affected seriously. Requirements of industrial wireless network and the wireless network standards are analyzed in this paper. The wireless communication quality model of IEEE 802.15.4 and IEEE802.11b is deduced. The simulation system based on this wireless communication quality model is established by Matlab. The simulation presents and compares communication quality of IEEE 802.15.4 and IEEE802.11b at the industrial noise range (typically between 20dB and 80 dB) and security level (IEC61508 defined standard- SIL1, SIL2 and SIL3). © 2005 - 2012 JATIT & LLS.

Proton exchange membrane fuel cells have been receiving more and more attention these recent years. It is expected to improve the output power of the fuel cell, so it is important to understand what are the relevant factors affecting the output power. Simulation can provide valuable insight and guidance for design, performance optimization, and cost reduction of fuel cells. Some factors which affect the generated output of proton exchange membrane fuel cell are study in this paper, and simulation results are shown and analyzed. It helps to understand the mechanism of the fuel cell and lay a good foundation for improving the output power.
