Efficient and stable photocathodes with versatility are of significance in photoassisted lithium-ion batteries (PLIBs), while there is always a request on fast carrier transport in electrochemical active photocathodes. Present work proposes a general approach of creating bulk heterojunction to boost the carrier mobility of photocathodes by simply laser assisted embedding of plasmonic nanocrystals. When employed in PLIBs, it was found effective for synchronously enhanced photocharge separation and transport in light charging process. Additionally, experimental photon spectroscopy, finite difference time domain method simulation and theoretical analyses demonstrate that the improved carrier dynamics are driven by the plasmonic-induced hot electron injection from metal to TiO2, as well as the enhanced conductivity in TiO2 matrix due to the formation of oxygen vacancies after Schottky contact. Benefiting from these merits, several benchmark values in performance of TiO2-based photocathode applied in PLIBs are set, including the capacity of 276 mAh g(-1 ) at 0.2 A g(-1 )under illumination, photoconversion efficiency of 1.276% at 3 A g(-1 ), less capacity and Columbic efficiency loss even through 200 cycles. These results exemplify the potential of the bulk heterojunction strategy in developing highly efficient and stable photoassisted energy storage systems.

In this paper,it is shown that for a residual set of points in a totally minimal system with finitely many commuting homeomorphisms,the set of return times to any non-empty open set contains a subset with positive multidimensional multiplicative upper Banach density,extending a previous result by Glasscock,Koutsogiannis and ***,we give some combinatorial properties of the sets with positive multidimensional multiplicative upper Banach density.

Painlevé Property and Complexiton Solutions of a Special Coupled KdV Equation

引用

Communications in Theoretical Physics 2008年第10期50卷 809-813页

作者： YANG jian-Rong MAO jie-jian Department of Physics Jiangxi Shangrao Normal College Shangrao 334001 China Department of Physics Ningbo University Ningbo 315211 China

A special coupled KdV equation is proved to be the Painleve property by the Kruskal＇s simplification of WTC method. In order to search new exact solutions of the coupled KdV equation, Hirota＇s bilinear direct method and the conjugate complex number method of exponential functions are applied to this system. As a result, new analytical eomplexiton and soliton solutions are obtained synchronously in a physical field. Then their structures, time evolution and interaction properties are further discussed graphically.

Soliton Solutions of Coupled KdV System from Hirota's Bilinear Direct Method

引用

Communications in Theoretical Physics 2008年第1期49卷 22-26页

作者： YANG jian-Rong MAO jie-jian Department of Physics Shangrao Normal College Shangrao 334001 China Department of Physics Ningbo University Ningbo 315211 China

With Hirota＇s bilinear direct method, we study the special coupled KdV system to obtain its new soliton solutions. Then we further discuss soliton evolution, corresponding structures, and interesting interactive phenomena in detail with plot. As a result, we find that after the interaction, the solitons make elastic collision and there are no exchanges of their physical quantities including energy, velocity and shape except the phase shift.

Formation Sites and Microscopic Conformation Study on the Konjac Glucomannan Molecular Helices

引用

Chinese Journal of Structural Chemistry 2010年第7期29卷 1084-1090页

作者： jian Wen-jie WANG Meng YAO Min-Na PANG jie Department of Biological Technology Xiamen Ocean Vocational College Xiamen 361012 China College of Food Science Fujian Agriculture and Forestry University Fuzhou 350002 China

In this work, the formation sites, helical parameters and hydrogen bond positions of Konjac glucomannan molecular helices were investigated using molecular dynamic simulation method. To our interest, the KGM chain is mainly composed by local left and right helix struetttres. The formation sites of KGM chain might locate at the chain-segments containing acetyl groups, and the left helix is the favorable conformation of KGM. Temperature-dependent molecule conformation study indicates that the right helix is dominant when the temperature is lower than 343 K, above which, however, the left helix is dominating （right helix disappears）. In addition, intramolecular hydrogen bonds in the left helix can be found at the -OH groups on C（2）, C（4） and C（6） of mannose residues; comparably, the intramolecular hydrogen bonds in the right helix can be mainly observed at the -OH groups on C（4） and C（6） of the mannose residues and C（3） of the glucose residues. In conclusion, molecular dynamic simulation is an efficient method for the microscopic conformation study of glucomannan molecular helices.

Is it necessary and feasible to increase the efficiency of 2-μm thulium laser resection of the prostate？

引用

Asian Journal of Andrology 2013年第4期15卷 453-454页

作者： jian Zhuo Shu-jie Xia Department of Urology First People's Hospital Schoolof Medicine Shanghai Jiaotong University Shanghai200080 China

wollm thulium laser has become widely accepted because of the resultant excellent homeostasis and rapid vapo rization in prostatectomy. It is necessary for us to increase the surgical efficiency because of increasing numbers of largersized, eld erly and highrisk BPH patients. We have made efforts to achieve this goal through continued improvement of the 2~m thu lium laser equipment, innovative methods tangerine technique, reasonable teaching mode and easily grasped learning curve. We prove it necessary and feasible to increase the efficiency of 2μm thulium laser resection of the prostate. Transurethral resection of the prostate （TURP） is generally considered the ＇gold standard＇ for the surgical treatment of benign prostatic hyperplasia （BPH）,1 but its use is generally restricted to small and medium sized prostates.2 The complications and morbidities that have been related to this pro cedure, which include blood loss and distur bances in the fluid balance, have created a need for the development and investigation of newer techniques. Several laser devices working at various wavelengths have been introduced in the last few decades.3 One of these, the 2~tm thulium laser, is a surgical laser with optional continuous or pulse wave modes and a wavelength tunable from 1.75 to 2.22 ].tm.4 This laser presents many advantages over the holmium laser, such as an improved spatial beam quality, a more precise tissue incision and the capacity to operate in optional continuouswave or pulse modes.5＇6 Since 2004, we have used the thu lium laser in clinical practice primarily for urogenital endoscopic procedures, and its use has become widely accepted because ofthe resultant excellent homeostasis and rapid vaporization. TURP AND OPEN PROSTATECTOMY TECHNIQUES Considering the size of China＇s ageing popu lation, surgical morbidity is expected to consis tently increase among urological patients. Thus, we expect to treat more and more complex patients suffering from such serious condition
