It lies within the Wuhan Economy and Technology Development Zone by the Lake Sanjiao.There are ten disciplines in the university: economics, law, education, literature, history, agriculture, science, engineering, medicine, and management. The University offers 42 undergraduate programs. There are about 1,000 full-time teachers, of whom 103 are full professors and about 400 associate professors. The number of full-time students is 15,600.Jianghan University was created as a technical college by the city government of Wuhan in 1981. It started a four-year undergraduate program in 1990s. In 2001, it merged with Huazhong University of Science and Technology and Wuhan Worker's Medical College, and later moved to the current campus.Jianghan University was accredited in October 2001 as a comprehensive university by the Ministry of Education of the People's Republic of China. It was established on the basis of the amalgamation of Jianghan University, Huazhong University of Science and Technology , Wuhan Institute of Education and Wuhan Workers Medical College. Wikipedia.

In the last two decades, metal-catalyzed controlled radical polymerization (CRP), or atom transfer radical polymerization (ATRP) has become a ubiquitous tool for the facile synthesis of a wide range of materials with specific macromolecular architectures. The complex plays an important role in ATRP, and for this purpose researchers put a great deal of effort on studying the effect of various complexes on polymerization. However, one of the disadvantages of a copper complex, the most extensively studied catalyst system in ATRP, is the contamination of polymers resulting from a high concentration of stable catalyst. Efficiently and economically removing the catalyst from the resultant polymers will provide a wide variety of new functional polymers for specialty applications, especially for large-scale industrial manufacture. Iron-based catalysts have attracted particular attention because of their low toxicity, low cost, abundance, and environmental friendliness, and thus many iron catalysts have been designed for ATRP. This article reviews the preparation of polymers using iron-catalyzed atom transfer radical polymerization, and is organized according to: (a) mechanistic considerations; (b) iron complexes and ligand types. © 2015 The Royal Society of Chemistry.

Bifacial dye-sensitized solar cells (DSCs) that are able to utilize the incidental light from both their front- and rear-side have received increasing attention in recent years. Compared to conventional DSCs that can only be operated under front-side illumination, bifacial design will allow DSCs to generate up to 50% more electrical power. Besides, bifacial DSCs can be easily made transparent and may find broad applications in building integrated photovoltaics (BIPV) as power-generating windows and roof panels. Transparent counter electrodes (CEs) are key to the fabrication of bifacial DSCs. However, despite the fact that conventional Pt CE can be made transparent, its high cost and scarce source may hinder the large-scale application of DSCs. Therefore, many efforts have been made to develop low-cost alternative CEs based on carbon materials, conducting polymers, inorganic compounds and their composites. In this feature article, we intend to pay special attention to the recent advances in the development of Pt-free transparent CEs and highlight their applications in bifacial DSCs.

Solvothermal reactions of tetrakis(4-pyridyloxymethylene)methane (TPOM) with deprotonated benzoate (L1) in the presence of acetate (L2) of copper in H2O/CH3OH with reactant ratio 1:2:2 under different synthesis temperatures produced two new complexes, namely, {[Cu 2(TPOM)2(L1)2(L2)2]·Guest} n (1), and {[Cu4(TPOM)(L1)2(L2) 4(OH)2]·6H2O}n (2). These complexes were characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. Complex 1 reveals a 3D crystal structure with a novel 2,3,4-connected 3-nodal topology constructed from the connection of Cu centers and TPOM ligands, which neutralized the mono-dentate carboxylates from different ligands coordinated to Cu ions. Complex 2 exhibits a distinct 3D framework with 2-nodal PtS topology, constructed from the connection of neutral Cu4 SBUs and TPOM ligands. The increasing reaction temperature must be responsible for the versatile coordination modes of carboxylates in 2 compared to the ones in 1, resulting in the formation of the distinct crystal structure. In addition, magnetic investigations on complex 2 revealed antiferromagnetic intra-tetramer interactions through the mixed hydroxo and carboxylato bridges.

A novel method has been developed for the determination of methimazole, which was based on the enhanced electrochemical response of methimazole at the acetylene black/chitosan composite film modified glassy carbon electrode. The electrochemical behavior of methimazole was studied at this film electrode by cyclic voltammetry and differential pulse voltammetry. The experimental results showed that methimazole exhibited a remarkable oxidation peak at 0.63V at the film electrode. Compared with the bare glassy carbon electrode, the oxidation peak current increased greatly, and the peak potential shifted negatively, which indicated that the acetylene black/chitosan film electrode had good catalysis to the electrochemical oxidation of methimazole. The enhanced oxidation current of methimazole was indebted to the nano-porus structure of the composite film and the enlarged effective electrode area. The influences of some experimental conditions on the oxidation of methimazole were tested and the calibration plot was examined. The results indicated that the differential pulse response of methimazole was linear with its concentration in the range of 1.0×10 -7 to 2.0×10 -5mol/L with a linear coefficient of 0.998, and in the range of 4.0×10 -5 to 3.0×10 -4mol/L with a linear coefficient of 0.993. The detection limit was 2.0×10 -8mol/L (S/N=3). The film electrode was used to detect the content of methimazole in rat serum samples by the standard addition method with satisfactory results. © 2011 Elsevier B.V.

The step response for hydraulic automatic gauge control (HAGC) determines the steel rolling speed and the steel sheet thickness in the process of rolling production. In this paper, the step response test process of HAGC was analysed, and a test approach was proposed for it. Based on that, the transfer function model of the step response test was established and simulated by using Matlab. In order to reduce the settling time and the overshoot, an adaptive proportional-integral-derivative (APID) link was presented in order to compensate for the input signal by using back propagation neural networks (BPNN). The experimental results show that the improved step response test model reaches the process requirements of HAGC, eliminates the jitter of the HAGC system at the start-up phase, and has better stability as well as faster response for steel sheet rolling. © 2015 Journal of Mechanical Engineering.
