摘要：The dynamic analysis and optimal design of reactive extraction are challenging due to high nonlinearity of model equations and tough decision of judging criteria. In this work, a dynamic rate-based method is developed on g PROMS platform to get easy access to the solutions of reactive extraction with phase splitting. Based on rigorous criteria, dynamic analysis from initial state to final equilibrium(e.g., evolution of phase composition, mass transfer rate and reaction rate) and optimal design of operating conditions(e.g., extractant dosage and feed molar ratio) are achieved. To illustrate the method, the esterification of n-hexyl acetate is taken as an example. The approach proves to be reliable in the analysis and optimization of the exemplified system, which provides instructive reference for further process design and simulation of reactive extraction.

摘要：Rational design of low‐cost and efficient electrocatalysts for ethanol oxidation reaction(EOR)is imperative for electrocatalytic ethanol fuel *** this work,we developed a copper‐doped nickel oxyhydroxide(Cu‐doped NiOOH)catalyst via in situ electrochemical reconstruction of a NiCu *** introduction of Cu dopants increases the specific surface area and more defect sites,as well as forms high‐valence Ni *** Cu‐doped NiOOH electrocatalyst exhibited an excellent EOR performance with a peak current density of 227 mA·cm^(–2)at 1.72 V versus reversible hydrogen electrode,high Faradic efficiencies for acetate production(>98%),and excellent electrochemical *** work suggests an attractive route of designing non‐noble metal based electrocatalysts for ethanol oxidation.

摘要：目的基于"天然产物共同药效团"策略探讨天然产物patriscabratine作用靶点,为其深入研究奠定基础。方法通过分子力场分析方法,初步确定与patriscabratine药效结构相似的天然产物aurantiamide acetate为模板分子,鉴于aurantiamide acetate是通过抑制组织蛋白酶L发挥的抗肿瘤活性,进一步基于组织蛋白酶L的晶体结构,利用分子对接方法,探讨两种天然产物与活性腔的作用模式并进行比对。进一步通过抗肿瘤活性验证计算结果。结果与结论经LigandScout软件分析表明两种天然产物作用方式基本一致,抗肿瘤活性结果表明二者的半数抑制浓度相似。初步确定patriscabratine的作用靶点为组织蛋白酶L。
