Anqing Teachers College is an institution of higher learning, located in Anqing, Anhui Province of the People's Republic of China.The history of the college dates back to 1897, when the earliest and largest provincial school in Anhui, Jinfu Academy , was relocated to Linghu Campus. Famed pundits and traditional scholars such as Liu Dagui, Wang Liangwu, Quan Zuwang and Yao Nai, all served as the headmaster . In 1898, emperor Guangxu of Qing Dynasty ordered it be renamed as Qiushi Academy . In 1902, it was called Anhui Grand Academy. Later, it became Anhui Military Academy, Anhui Army's Academy, and Anhui Judicial and Political College. In 1928, Anhui Provincial University was formed here. In 1946, it became National Anhui University, and thus attained its climax in Chinese modern history of higher education.After the establishment of the People's Republic of China, due to the drift of the political center, the school witnessed a series of alterations over the time, though the education mission has never been discontinued. It once became a Navy Academy, a Normal College, and a branch campus of Anhui Normal College. In May 1980, upon the approval of the State Council, it was renamed Anqing Teachers College. In 1998, the college held its 100th anniversary celebration.In 2010, Anqing Teachers College established a sister institution partnership with Salisbury University in the US state of Maryland.

Herein, we report a novel and facile route for the large-scale fabrication of 2D porous NixCo3-xO4 nanosheets, which involves the thermal decomposition of NixCo1-x hydroxide precursor at 450 °C in air for 2 h. The as-prepared 2D porous Ni xCo3-xO4 nanosheets exhibit an enhanced lithium storage capacity and excellent cycling stability (1330 mA h g-1 at a current density of 100 mA g-1 after 50 cycles). More importantly, it can render reversible capacity of 844 mA h g-1, even at a high current density of 500 mA g-1 after 200 cycles, indicating its potential applications for high power LIBs. Compared to pure Co 3O4, the reduction of Co in NixCo 3-xO4 is of more significance because of the high cost and toxicity of Co. The improved electrochemical performance is attributed to the 2D structure and large amounts of mesopores within the nanosheets, which can effectively improve structural stability, reduce the diffusion length for lithium ions and electrons, and buffer volume expansion during the Li + insertion/extraction processes. © 2014 American Chemical Society.

Particle swarm optimization (PSO) is inspired by social behaviors of bird flocking, gravitational search algorithm (GSA) is based on the law of gravity and interaction between masses, and both of them are pertain to meta-heuristic algorithms. A novel hybrid particle swarm optimization and gravitational search algorithm (HPSO-GSA), having attributes of PSO and GSA, is proposed in this paper to solve economic emission load dispatch (EELD) problems considering various practical constraints. These constraints consist of the generator ramp rate limits, non-convex and discontinuous nature of prohibited operating zones, non-smooth characteristic of valve-point effects, multiple fuels type of generation units, and transmission losses in realistic power systems. The proposed approach embodies interesting concepts and fully incorporates the social essence of PSO with the motion mechanism of GSA. The proposed HPSO-GSA adopts co-evolutionary technique to simultaneously update particle positions with PSO velocity and GSA acceleration. HPSO-GSA, therefore, is expected to obtain an efficient balance between exploration and exploitation. From results of canonical benchmark test functions, HPSO-GSA does significantly improve PSO and GSA with better performance. As a real application, the EELD problems on five test systems including different constraints are solved by the HPSO-GSA to assess the optimizing performance of the proposed hybrid approach. The results obtained confirm the potential and effectiveness of the proposed approach compared to PSO, GSA and other algorithms published in the recent state-of-the art literatures for the solution of the EELD problems. © 2013 Elsevier Ltd.

Bi 2WO 6 is incorporated on graphene sheets using a facile refluxing method to improve its photocatalytic performance. Remarkable three times enhancement in photodegradation of Rh.B is observed on Bi 2WO 6/graphene composite compared with pure Bi 2WO 6 under visible light irradiation. This improvement is attributed to the longer electron lifetime of excited Bi 2WO 6 as the electrons even if holes are injected to graphene instantly at the site of generation, leading to a maximized charge separation. This study demonstrated that the graphene as supporter could provide an effective way for enhancing photocatalytic performance of semiconductor photocatalysts by acting as charge transfer channel. © 2011 Elsevier B.V.

This study reports a strategy that allows one to finely tune the distance between Ag nanoparticles decorated on thermoresponsive microgels to create vast 'hot spots' for electromagnetic enhancement. The dynamic gap (i.e. the interparticle distance) can be tuned easily because the microgel template undergoes a phase transition upon changing the temperature. This change could increase the SERS intensity for three orders of magnitude. This journal is © The Royal Society of Chemistry 2013.

CdS/MoS2 heterostructures with a branch-like morphology have been prepared via a one-pot hydrothermal method. The as-prepared CdS/MoS 2 heterostructures exhibited enhanced photocatalytic activity and photostability for the degradation of organic dyes. It is believed that the 2D MoS2 sheets supporting CdS form a large number of interfaces, which may significantly increase the separation of electron/hole pairs, thus greatly enhancing the photocatalytic activity. On the other hand, the matched energy bands of the CdS/MoS2 heterostructure also allow hole transfer from CdS to MoS2, thus reducing CdS corrosion. © 2014 The Royal Society of Chemistry.

In this study, we have demonstrated a Z-scheme photocatalytic system using Ag@AgCl encapsulated with graphene oxide (GO) (AEGO) composites, where GO and AgCl act as a highly activated photocatalyst, and metallic Ag shuttles photogenerated electrons from the excited GO and AgCl under visible light irradiation. The electron-hole pairs of the low energy level could be recombined in space by metallic Ag as a solid-state electron mediator, the remaining electron-hole pairs of the high energy level are for two photochemical reactions that operate in parallel. The Z-scheme photocatalytic system from the AEGO composite displays a much higher photocatalytic activity than Ag@AgCl-reduced graphene oxide (RGO) with the same quantitative graphene loading (15 wt%) for the degradation of methylene blue (MB). This work may provide a guide to the design of photocatalysts by the use of GO directly. © 2014 The Royal Society of Chemistry.

Stacking fault (sf) and twin defects in Pd, Au-Pd, and Au-Pd-Pt clusters are theoretically studied, which has affected the mechanical properties of face centered cubic (fcc) metal and alloy clusters. The stable structures are located with Gupta potential by the density functional theory (DFT)-fitted and averaged parameters. In Pd30-200 clusters, besides morphologies, such as Mackay icosahedra (Ih) and Marks decahedra (Dh), fcc, sf-fcc, and twin-fcc motifs are identified. Furthermore, the growth pattern of twin-fcc is based on the 50- and 79-atom motifs with high D3h symmetry, and the construction method for all possible D3h twin-fcc is proposed starting from centered and uncentered truncated octahedra. Moreover, a strong competition among fcc, sf-fcc, twin-fcc, Ih, and Dh is found in AumPdn (m + n = 50 and 61) and 55-atom Au-Pd-Pt clusters. The segregation phenomena of the Au, Pd, and Pt atoms in the Au-Pd-Pt clusters are studied and further compared with Au-Pd, Au-Pt, and Pd-Pt clusters. © 2014 the Partner Organisations.

To investigate the effect of organic anions on the coordination frameworks, we synthesized three new complexes, namely, Co(SDBA)(BIMB) (1), Co 2(SA)(BIMB)1.5(H2O) (2) and Co(FBA)(BIMB) 0.5·H2O (3) (H2SDBA = 4,4′-dicarboxybiphenylsulfone, H4SA = 3,3′,4,4′- diphenylsulfonetetracarboxylate acid and H2FBA = 4,4′- (hexafluoroisopropylidene)bis(benzoic acid)), which were obtained by the reactions of 4,4′-bis(1-imidazolyl)biphenyl (BIMB), and three V-shaped aromatic polycarboxylates as organic anions with Co(NO3) 2·6H2O. Single crystal structure analysis shows that complex 1 features a 3-fold interpenetrating three-dimensional (3D) framework with CdSO4-type topology. Complex 2 has a previously unknown 3D trinodal (4,4,6)-connected framework with a Schläfli symbol of (4·64·8)2(43·6 3)2(44·610·8). Complex 3 exhibits a three-dimensional 2-fold interpenetrating pillared helical-layer open framework of α-Po topology based upon binuclear paddlewheel units. The results reveal that the carboxylic building blocks with different conformations play a significant role in promoting the diversity of the observed structural motifs. The magnetic properties of the three complexes as well as the SHG and ferroelectric properties for 1 have also been investigated. Finally, theoretical calculations were carried out on the conformation of the BIMB ligand in the three complexes. © 2013 The Royal Society of Chemistry.
