Hydrothermal synthesis of silver nanoparticles in Arabic gum aqueous solutions

引用

Transactions of Nonferrous Metals Society of China 2015年第6期25卷 2081-2086页

作者：黎应芬甘卫平周健鲁志强杨超戈田田中南大学材料科学与工程学院长沙410083

Finely divided silver nanoparticles were synthesized via the hydrothermal method. Arabic gum （AG） was used as both the reductant and steric stabilizer without any other surfactant. By adjusting the reaction temperature, mass ratio of AG to AgNO3, and reaction time, silver nanoparticles with different morphological characteristics could be obtained. The products were characterized by UV-Vis, FTIR, TEM, SEM, and XRD measurements. It was found that temperature and AG played an important role in the synthesis of mono-disperse silver nanoparticles. Well dispersed and quasispherical silver nanoparticles were obtained under the optimal synthesis conditions of 10 mmol/L AgNO3, m（AG）/m（AgN03）= l：1, 160 ℃ and 3 h.

Optimal Operation of Multi Alkaline Electrolyzers Considering Flexible Electrical and Hydrogen Load

引用

Dianwang Jishu/Power System Technology 2025年第1期49卷 84-92页

作者： tian, Xueqin Feng, Yajie Yuan, Tiejiang Yang, Fuyuan ge, Yangyang School of Electrical Engineering Dalian University of Technology Liaoning Province Dalian 116024 China Sate Grid Economic and Technological Research Institute Co. Ltd. Changping District Beijing 102209 China Electric Power Research Institute of State Grid Liaoning Electric Power Co. Ltd. Liaoning Province Shenyang 110006 China

Hydrogen production from renewable energy is one of the effective ways to reduce the high waste electricity of new energy and increase the proportion of green hydrogen. The multi-alkaline electrolyzers optimization operation strategy is proposed considering flexible electric loads and hydrogen loads in response to the optimization operation of large-scale new energy hydrogen production systems and high abandonment of electricity. Firstly, after considering the demand for electricity and hydrogen loads on the user side, transferable electric loads and hydrogen load models are established based on the transferable characteristics of electricity and hydrogen. Secondly, the multi-stack electrolyzer optimization operation strategy is proposed, considering the operating characteristics of a single electrolytic cell and electrolytic efficiency. Satisfying system operation constraints and optimizing the operating model to minimize economic cost is established and solved using the Yalmip toolbox and Cplex. The calculation results show that the participation of transferable loads can promote wind power consumption, reduce system electricity consumption, and improve the system economy. Compared with the multi-stack electrolyzer rotation strategy, the strategy proposed in this article effectively reduces the start and stop times of the electrolyzer, stabilizes the standard deviation of electrolysis cell power fluctuation within 0.27, improves the service life of electrolyzer arrays and increases the overall electrolysis efficiency to about 57%. © 2025 Power System Technology Press.

Estimations of Parametric Functions under a System of Linear Regression Equations with Correlated Errors

引用

Acta Mathematica Sinica,English Series 2010年第10期26卷 1927-1942页

作者： Yong ge tian China Economics and Management Academy Central University of Finance and Economics Beijing 100081 P. R. China

Estimations of parametric functions under a system of linear regression equations with correlated errors across equations involve many complicated operations of matrices and their generalized inverses. In the past several years, a useful tool -- the matrix rank method was utilized to simplify various complicated operations of matrices and their generalized inverses. In this paper, we use the matrix rank method to derive a variety of new algebraic and statistical properties for the best linear unbiased estimators （BLUEs） of parametric functions under the system. In particular, we give the necessary and sufficient conditions for some equalities, additive and block decompositions of BLUEs of parametric functions under the system to hold.

For any element a in a generalized 2^n-dimensional Clifford algebra Lln （F） over an arbitrary field F of characteristic not equal to two, it is shown that there exits a universal invertible matrix Pn over Lln（F） such that Pn^-1DnPn= φ（α）∈F^2n×2n, where φ（a） is a matrix representation of α over and Dα is a diagonal matrix consisting of a or its conjugate.
