Zhengzhou University of Light Industry is a public university located in Zhengzhou, Henan, People's Republic of China.Address: 5 DongFeng Road, Zhengzhou, Henan province, P.R.China , Post Code: 450002Founded in 1977, Zhengzhou University of Light Industry was administered successively by the Ministry of Light Industry, the National Council of Light Industry, and the State Economic and Trade Commission until it was transferred to Henan Province as an institution co-administered by the central and local authorities in 1998. Presently it has evolved into a multi-disciplinary engineering focused university promoting coordinated development of other disciplines such as science, Liberal arts, Economics, Management, Law and Pedagogy.The University has accelerated its development at a breathtaking pace by educational reform and innovation, holding the educational philosophy of “putting students first, dedication to learning, improving the quality of teaching and serving society,” and acting on the university motto of “nothing is too difficult for the willing mind”. Consisting of 15 colleges or departments, ZZULI offers 47 undergraduate programs, 26 master programs and 2 programs in the Master of Engineering. It is also authorized to award Master’s Degrees to the applicants with the equivalent education of the postgraduates. At present, the enrollment of students has exceeded 15,000, which includes the undergraduates and postgraduates. Wikipedia.

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. Source

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.

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. Source

A strongly coupled mesoporous SnO2-graphene hybrid has been prepared via direct nucleation, growth, and anchoring of a SnO2 nanocrystal on graphene substrate under microwave irradiation followed by heat-treatment. Investigations reveal that the well-dispersed SnO2 nanocrystals with a uniform particle size of 3-5 nm are homogeneously distributed on the surface of graphene through strong chemical attachment and electrical interaction. The formed structure exhibits a high specific surface area (280.7 m2 g-1) and an ideal synergistic effect, which can provide improved activity and durability for the electrochemical and photocatalytic reaction. Lithium-ion battery performance and photocatalytic activity of the resultant mesoporous SnO2-graphene hybrid are thoroughly investigated. In comparison to bare SnO2 nanoparticles, the hybrid shows substantial enhancement in electrochemical lithium storage properties and photocatalytic hydrogen evolution. More strikingly, the as-synthesized SnO2-graphene hybrid anode could deliver initial discharge and charge capacities of 2445.7 and 1329.4 mAh g-1 with a high initial Coulombic efficiency (54.4%), as well as an excellent cycling stability. © The Royal Society of Chemistry 2013.

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.
