In this paper, we are concerned with the partial regularity of the suitable weak solutions to the fractional MHD equations in Rn for n = 2, 3. In comparison with the work of the 3D fractional Navier-Stokes equations obtained by Tang and Yu in [Partial regularity of suitable weak solutions to the fractional Navier-Stokes equations, Comm. Math. Phys. 334 (2015) 1455-1482], our results include their endpoint case α = 3/4 and the external force belongs to a more general parabolic Morrey space. Moreover, we prove some interior regularity criteria just via the scaled mixed norm of the velocity for the suitable weak solutions to the fractional MHD equations. © 2016 World Scientific Publishing Company.

City landscape color has an important significance in shaping the visual image, the city culture and history of the city. However, for the city color at moment, the problem of how to use the city characteristic exists in the present stage of our country, the loss of city culture and geographical characteristics of the landscape color is not rare. Therefore, the author did an in-depth research to the Japanese city landscape color system that in the forefront of international research in this area, summarizes the present landscape main color setting, in order to provide some helpful advices and reference to the city landscape color planning criterion. © 2014, Journal of Chemical and Pharmaceutical Research.

Two new oxidovanadium(V) complexes, [VO2L1] (I) and [VO2L2] (II), where L1 and L2 are the deprotonated forms of 4-methyl-2-[(2-morpholin-4-ylethylimino)methyl]phenol (HL1) and 2-[(2-isopropylaminoethylimino) methyl]-4-trifluoromethoxyphenol (HL2), respectively, have been prepared and characterized by physico chemical methods and single crystal X-ray diffraction (CIF files CCDC nos. 1443671 (I), 1443672 (II)). The V atom in each complex is coordinated by the phenolate oxygen, imino nitrogen and amino nitrogen of the Schiff base ligand, and two oxo groups, forming trigonal-bipyramidal geometry. The oxidation of olefins with the complexes as catalyst was evaluated, which indicated that both complexes showed effective catalytic efficiency in oxidation of several aliphatic and aromatic substrates by using tert-butyl hydrogen peroxide as oxidant. © 2017, Pleiades Publishing, Ltd.

Two new copper(II) complexes, [Cu(L1)2] (I) and [Cu(L2)2] (II), where L1 = 2-bromo-4-chloro- 6-(isopropyliminomethyl)phenolate and L2 = 2-bromo-4-chloro-6-[(2-hydroxyethylimino)methyl]phenolate, have been prepared and structurally characterized by X-ray crystallography (CIF files CCDC nos. 1445936 (I) and 1445935 (II)). In both complexes, the Cu atoms are coordinated by two phenolate oxygen and two imino nitrogen, giving square planar geometry. The complexes have been tested on various strains of bacteria to study their antibacterial effects. © 2017, Pleiades Publishing, Ltd.

In this paper, we are concerned with the local regularity of suitable weak solutions to the 3D Navier-Stokes equations and its generalized case with fractional power of the Laplacian (-Δ)α (3/4≤α<1). In the first part, we derive some D(u)-regularity criteria in terms of the deformation tensor D(u) for the classical Navier-Stokes equations. In the second part, for the fractional case, we obtain some regularity conditions for suitable weak solutions including the velocity (u), the gradient of the velocity ∇(u), the rotation tensor Ω(u) and the deformation tensor D(u). This generalizes the results obtained by Gustafson et al. (2007). © 2016 Elsevier Ltd. All rights reserved.

Research on lignin deconstruction has recently become the center of interest for scientists and companies worldwide, racing towards harvesting fossil-fuel like aromatic compounds which are so durably put together by plants as products of millions of years of evolution. The natural complexity and high stability of lignin bonds (also as an evolutionary adaptation by plants) makes lignin depolymerization a highly challenging task. Several efforts have been directed towards a more profound understanding of the structure and composition of lignin in order to devise pathways to break down the biopolymer into useful compounds. The present contribution aims to provide an overview of key advances in the field of lignin depolymerisation. Protocols and technologies will be discussed as well as critically evaluated in terms of possibilities and potential for further industrial implementation. © the Partner Organisations 2014.

The rational construction of coordination polymers (CPs), normally existing as infinite crystalline lattices extended from inorganic vertices and organic struts, essentially benefits from the development of crystal engineering strategies. In this review, we summarily comment on the key advances in the design of CPs using mixed-ligand synthetic strategy and discuss the relationship between the specifically selected mixed organic ligands and the resulting CPs. Significantly, fine tuning on the structural features of organic ligands, such as spacers, positional isomers, and substituents, can lead to a delicate regulation of the diverse network structures of CPs. Additionally, such mixed-ligand coordination assemblies may also be heavily affected by metal ion, synthetic route, and some other external stimuli such as solvent and pH condition, etc. The advantages of mixed-ligand systems as promising approaches to construct CPs-based crystalline materials with interesting structures and useful properties will also be demonstrated. © 2012 Elsevier B.V.

We present high-resolution spectroscopic observations for a sample of 19 weak-line T Tauri stars (WTTSs). Based on these observations and data of 108 WTTSs taken from the literature, we derive lithium abundances for 127 WTTSs. Investigation of a possible relation between lithium and rotation in WTTSs shows that: (1) rapidly rotating WTTSs have comparatively lower lithium abundances than their slower rotating counterparts; (2) in the spectral-type range G0-K0, most of the WTTSs share the same Li content irrespective of their T eff; and (3) active late-type binaries do not obey the correlation between lithium abundances and rotation periods, since the tidally locked rotation of the late-type binary system leads naturally to slower lithium destruction rates. © 2010.

A novel AB5-alloy oxide/graphene composite has been fabricated through a facile mixing of commercial oxidized AB5-alloy and graphene as anode materials for lithium ion batteries. Electrochemical measurements show that the composite delivers an initial discharge capacity of 1639.7 mAh g -1 and maintains a high reversible capacity of 418.2 mAh g -1 up to 180 cycles. The enhanced cycling stability could be attributed to the fact that AB5-alloy oxide/graphene composite can accommodate large volume change during cycling and maintain good electronic contact. © 2013 Elsevier B.V.

This paper studies the problem of stabilization for sampled-data neural-network-based control systems with an optimal guaranteed cost. Unlike previous works, the resulting closed-loop system with variable uncertain sampling cannot simply be regarded as an ordinary continuous-time system with a fast-varying delay in the state. By defining a novel piecewise Lyapunov functional and using a convex combination technique, the characteristic of sampled-data systems is captured. A new delay-dependent stabilization criterion is established in terms of linear matrix inequalities such that the maximal sampling interval and the minimal guaranteed cost control performance can be obtained. It is shown that the newly proposed approach can lead to less conservative and less complex results than the existing ones. Application examples are given to illustrate the effectiveness and the benefits of the proposed method. © 2010 IEEE.
