High-quality single-crystal CdSe nanoribbons and their optical properties

引用

Optoelectronics Letters 2008年第3期4卷 161-164页

作者： HOU D.D LIU y. K ZAPIEN J. A SHAN y. y LEE S. T Department of Physics Yunnan Normal University Kunming 650092 China Center of Super-Diamond and Advanced Films （COSDAF） and Department of Physics and Material Science City University of Hong Kong Hong Kong SAR China

Large-scale synthesis of single-crystal CdSe nanoribbons is achieved by a modified thermal evaporation method, in which two-step-thermal-evaporation is used to control CdSe sources＇ evaporation. The synthesized CdSe nanoribbons are usually several micrometers in width, 50 nm in thickness, and tens to several hundred micrometers in length. Studies have shown that high-quality CdSe nanoribbons with regular shapes can be obtained by this method. Room-temperature photolumines-cence indicates that the lasing emission at 710 nm has been observed under optical pumping （266 nm） at power densities of 25-153 kW/cm^2. The full width half maximum （FWHM） of the lasing mode is 0.67 nm

Influence on Microstructure of Micronized Sand as Cement Replacement in Cementitious Materials

引用

武汉理工大学学报 2010年第17期32卷 152-157页

作者： WANG y yE G Faculty of Civil Engineering and geosciences Delft University of Technology2006 GA Delft 2600the Netherlands Magnel Lab for Concrete Research Ghent UniversityGhent 9050Belgium

In this study,micronized sand is selected as a kind of filler to partially replace cement in cementitious materials. This filler is considered as chemically inert material,which can not react with water or hydration products,but still indirectly influences the hydration in a positive way. In the experimental program,non-evaporable water test was carried out to determine the degree of hydration of cement paste with and without micronized sands. The influence of different finenesses of sand particles,240 m2/kg,400 m2/kg and 1 300 m2/kg,and different curing ages were investigated. The SEM image analysis was used to characterize the morphological changes of microstructure by the presence of the micronized sand during the cement hydration process. Hydration reaction is enhanced by the use of inert micronized sands. The fineness of micronized sands influences the degree of hydration a lot. The fineness factor has been taken into account in the simulation. There is a clear interface area between sand particle and hydration products.

A Remark on Eigenfunction Estimates by Heat Flow

Advances in Pure Mathematics 2016年第7期6卷 512-515页

作者： Huabin ge yipeng Shi Department of Mathematics Beijing Jiaotong University Beijing China College of Engineering Peking University Beijing China

In this paper, we consider L∞ estimates of eigenfunction, or more generally, the L∞ estimates of equation -Δu=fu. We use heat flow to give a new proof of the L∞ estimates for such type equations.

Dynamics of a multi-mode maximum entangled coherent state over an amplitude damping channel

引用

Chinese Physics B 2011年第11期20卷 67-73页

作者： A.El Allati y.Hassouni N.Metwally Faculté des Sciences Laboratoire de Physique Theorique URAC 13Université Mohammed V-Agdal The Abdus Salam International Centre for Theoretical Physics Mathematics Department College of ScienceUniversity of Bahrain Mathematics Department Faculty of ScienceSouth Valley University

The dynamics of the maximum entangled coherent state traveling through an amplitude damping channel is investigated. For small values of the transmissivity rate, the traveling state is very fragile to this noise channel, which suffers from the phase flip error with high probability. The entanglement decays smoothly for larger values of the transmissivity rate and speedily for smaller values of this rate. As the number of modes increases, the traveling state over this noise channel quickly loses its entanglement. The odd and even states vanish at the same value of field intensity.

Applied Mathematics and Mechanics(English Edition) 2014年第7期35卷 913-924页

作者：杨明歌黄南京 Department of Mathematics Luoyang Normal University Department of Mathematics Sichuan University

By a coincidence theorem, some existence theorems of solutions are proved for four types of generalized vector equilibrium problems with moving cones. Applications to the generalized semi-infinite programs with the generalized vector equilibrium constraints under the mild conditions are also given. The results of this paper unify and improve the corresponding results in the previous literature.
