In this study, nickel oxide (NiO) thin films are deposited on three-dimensional nickel foam by a facile two-step method for application in Li-ion batteries (LIBs). These NiO films on Ni foam are tested as Li-ion batteries anodes. The rough NiO thin film with the shortest deposition time (3 min) shows the best Li-ion battery performance. A high specific capacity of 917 mAh g-1 is achieved at a charge-discharge current of 0.5 C and even after 100 cycles, a capacity of 838 mAh g-1 is still retained. The electrode also shows a good rate capability. This study shows that NiO electrode prepared with this method can be a promising candidate for LIBs anodes materials. © 2016 The Institution of Engineering and Technology.

Three-fold dendrites of Ce(OH)CO 3 with multilayer caltrop have been synthesized on a large scale by means of a complexing agent assisted solution route. The shape of these as-prepared architectures can be tuned effectively by controlling the reaction conditions, such as reaction time and the molar ratio of complexing agent/Ce 3+. As a typical morphology, the growth process of 3-fold dendrites of Ce(OH)CO 3 with multilayer caltrop has been examined, and a possible mechanism is discussed. The phase and morphology of the as-prepared product have been characterized by means of powder X-ray diffraction (XRD), (high resolution) transmission electron microscopy (HRTEM), and scanning electron microscopy (SEM). The morphology of dendrites is sustained after thermal decomposition-oxidation Ce(OH)CO 3 to CeO 2. To extend this method, La(OH)CO 3 and Eu 3+/Ce(OH)CO 3 dendritic structures can also be achieved at similar reaction conditions. After similar heat treatment in an oven, their dendritic structures are also retained. La(OH)CO 3 completely transforms into La 2O 2(CO 3), and Eu 3+/Ce(OH)CO 3 changes to Eu 3+/CeO 2. The photoluminescent properties of Eu 3+/Ce(OH)CO 3 and Eu 3+/CeO 2 dendrites have also been investigated. This work sheds some light on the design of well-defined complex nanostructures. © 2011 American Chemical Society.

We analytically study the Wigner function (WF) for the two-variable Hermite polynomial state (TVHPS) and the effect of decoherence on the TVHPS in thermal environment. The nonclassicality of the TVHPS is investigated in terms of the partial negativity of the WF which depends on the polynomial orders m,n and the squeezing parameter r. We also investigate how the WF for the TVHPS evolves in the thermal environment. At long times, the TVHPS decays to thermal, a mixed Gaussian state, within the thermal environment. © 2013 Springer Science+Business Media New York.

In this paper, we introduce the Hermite polynomial's coherent state (HPCS) |α)H, which is defined as Hn(X)|α) up to a normalization constant and where Hn(X) is the coordinate operator's Hermite polynomial of order n and |α) = exp(-(1/2)|α|2 + aa†)|0). This state may be produced by the superposition of some different photon added coherent states when n = 2. The mathematical and physical properties of HPCS are also studied. It is shown that HPCS has remarkable nonclassical state features such as sub-Poissonian and squeezing properties. © 2012 Optical Society of America.

This paper performs feature analysis and image understanding on an image principle function and sparse coefficients of different artistic styles, acquired by sparse coding algorithms. Then the obtained features are used to study classification implementation of different artistic works. We adopt absolute value of kurtosis as sparse measuring standard of parameter component ensuring the sparsity and independency of coefficients. Simultaneously, fixed parameter component variance items are introduced to target function, to ensure the balance between minimal image reconstruction error and sparse penalty function. We also adopt Gabor wavelet to initialize Sparse Coding (SC) feature principle function to search optimal basis vectors, which further raises convergence speed of SC network. The experiments verify the sparse coding algorithm maximized by kurtosis which can be used to classify styles of artistic works. © 2016, UK Simulation Society. All rights reserved.

The regional brand development is to enable regional brands sustained, orderly, stable and coordinated development under the constraints of the four elements of the government, business, social and other intermediary organizations, from this, the structural model of the regional brand development is formed. The article argues that the regional brand building and development must proceed from the following points: First, in the social subsystem, focus on the cultivation of social cultural, change people's traditional concept, nurture a kind of social culture of brand share, and strengthen the basic research for technological innovation; second, in the enterprise subsystem, improve product quality, good brand marketing, management and technological innovation; third, government subsystem, in terms of policy, capital, infrastructure, branding promotion, offer support; fourth, in other intermediary organizations subsystem, give full play the coordinating role of industry associations, human resources, financial resources, legal advice, and other aspects are inseparable from intermediary organizations. © 2013 Springer-Verlag Berlin Heidelberg.

Whether in the formal or informal public interest organization, leadership has a crucial role for organization's establishment, survival and development. However, NGO development in China is still in the initial stage, lack of good leadership groups, especially lack of leadership. Combination of organizational life cycle theory and NGO characteristics, life cycle of NGO can be divided into six stages, that is exploration stage, start-up stage, development stage, mature stage and Decline and recovery stage. After analyze NGO Executive Leaders characteristics at different stage of lifecycle, the article have come up with a couple of principle of selecting executive leaders of NGO that are perhaps worth considering, then point out four selection channels. Finally, this paper from the perspective of life cycle theory explores how to scientifically select the NGO leader and leadership skills systematic training model and training pattern, self-growth and hatch. © Springer-Verlag Berlin Heidelberg 2013.

Using improved EF Model, this paper calculated the Sustainable Development level of Anhui province between 2004 and 2013.The results show that (1) the total Per capita EF was constantly increasing in Anhui province from 1.2413 hm2 in 2004 to 1.6157 hm2 per person in 2013, (2) the total Per capita EC is increasing from 0.2471 hm2 to 0.2640 hm2 per person, which is much smaller than the total Per capita EF. And the ecological deficit shows Anhui province is under huge ecological pressure and the economic and social development is unsustainable; (3) the EF diversity index rose from 1.2876 hm2 to 1.3902 hm2 per person, which shows that the EF distribution is increasingly imbalanced and the ecological system is in steady; (4) the sustainable development index increased from 1.5524 hm2 to 2.2460 hm2 per person, which shows that Anhui ecological capacity is gradually improving despite its ecological deficit.

Symmetrical silver phosphate (Ag3PO4) crystals with porous structure were grown by a facile controllable route in aqueous solution. The Ag3PO4 crystals have a cubic-type structure and the morphologies are distinctive under different conditions. The crystals had high purity, were well-crystallized and were free of secondary phases by powder X-ray diffraction, IR, Raman spectra, scan electron microscopy (SEM), transmission electron microscopy (TEM), and selected area electron diffraction (SAED). It is interesting that the different crystal faces of the crystals have high physical-chemical-biological activity and large surface areas, so as to act as high activity micro-reactors (HAMs). The HAMs can effectively improve the photocatalytic activity and bacteriostatic activity of the Ag3PO 4 crystals. Furthermore, we proposed a possible growth mechanism and detailed morphology transformation process of Ag3PO4 crystals with different properties. This journal is © The Royal Society of Chemistry.
