Solubility measurement and thermodynamic modeling of carbamazepine (form Ⅲ) in five pure solvents at
In this work, the solubilities of carbamazepine (CBZ) (form Ⅲ) in ethyl acetate, methyl acetate, ethylene glycol, chloroform and cyclohexylamine were determine
把PLC和变频器应用到船舶日用水供水装置中,采用PID控制方式,设计了恒压供水装置的控制系统,综合了PLC可靠性高、控制功能强和变频器可实现无级调速的优点,实现了恒压供水的目标,减小了装置的能耗、体积、重量和噪音,提高了装置的可靠性、经济性和安全性。
高比能兼具功率密度的电池在特殊国防军用领域有着极高的应用价值。锂氟化碳电池作为目前比能量最高的一种锂/固体正极电池,具有在水中兵器电源中进一步发展的潜力。本文采用不同电极参数组装的锂/氟化碳软包电池,对其倍率放电性能进行试验并分析,最后得出不同电极参数对电池性能的影响。
Functionalized metal–organic frameworks with strong acidity and hydrophobicity as an efficient catal
In the dehydration of fructose to 5-hydroxymethyl furfural(HMF),in situ produced water weakens the acid strength of the catalyst and causes the rehydration of HMF,causing unsatisfactory catalytic activity and selectivity.In this work,a class of benzenesul
Experimental investigation on the effect of surface characterization of electrodes on the gas bubble
In the flooded lead_acid batteries(FLAB),gas bubbles are initially formed on the surface of the electrodes,which are produced by electrochemical reactions,and then released into the electrolyte.In the present investigation,the effect of surface characteri
Polyoxymethylene dimethyl ethers(CH3-O-(CH2O)n-CH3,PODEn,n>1)can be added to diesel to reduce air pollution caused by incomplete combustion.Driven by this need,a cost-effective and efficient synthe
2018年10月4日,日本“苍龙”级潜艇11号艇“凰龙”号在三菱重工举行了下水仪式,为全球首艘装备锂离子动力电池的潜艇,随后法、德、韩等国也相继宣布其潜艇锂离子动力电池已具备装艇条件,标志着潜艇动力电池开始进入锂电时代。本文根据国外相关报道及文献资料,对国外潜艇所用的锂离子动力电池从技术角度进行了分析,并与铅酸蓄电池进行了对比。
Separation of As and Bi and enrichment of As, Cu, and Zn from copper dust using an oxidation-leachin
Copper dust with high arsenic content is a hazardous waste that should be treated properly. Herein, the copper dust is oxidized, leached, and separated at room
A multiphase computational fluid dynamics(CFD)model coupled with the population balance equation(PBE)was developed in a homogeneous air-kerosene bubble column under elevated pressure(P).The specific pressure drop(ΔP/L),gas holdup(αG),and Sauter
Enhanced adsorption of phenol from aqueous solution by carbonized trace ZIF-8-decorated activated ca
Trace zeolitic imidazolate framework-8(ZIF-8)-decorated activated carbon(AC)pellets were synthesized by a facile wet impregnation technique.After pyrolysis of the above composite material,the obtained carbon had a large surface area and pore volume,with t
