Isobaric vapor–liquid equilibrium for binary system of aniline+methyl-N-phenyl carbamate

In this study,the quasi-static ebulliometric method was used to measure both of the vapor pressures of methyl N-phenyl carbamate(MPC),and the isobaric vapor–liquid equilibrium(VLE) data of the aniline and MPC binary system.The measured vapor pressure data of MPC,at different temperature ranging from 369.60 to 389.54 K,fitted well with the Antoine equation.The VLE data for the aniline and MPC system at(2.00,4.00,6.00,7.00 and 8.00) k Pa were correlated by both of nonrandom two-liquid(NRTL) and Wilson models.The parameters of the two models were obtained by regressing the experimental data,with the absolute temperature deviations of 0.54 K and 0.53 K,respectively.The relative volatility of the binary system calculated was all far more than 1,which gives the conclusion that the high purity MPC can be separated from aniline and MPC binary system by rectification or distillation technology.

Reduced-order design of Robust H_∞ Controller for an Inertial Stabilized Aerial Platform

The uncertainty disturbance is one of the main disturbances that seriously influences the stabilization precision of an aerial inertially stabilized platform(ISP)system.In this paper,to improve the stabilization precision of the ISP under disturbance uncertainty,a robust H∞controller is designed in this paper.Then,the reduction order is carried out for high-order controllers generated by the robust H∞loop shaping control method.The application of the minimum implementation and balanced truncation algorithm in controller reduction is discussed.First,the principle of reduced order of minimum implementation and balanced truncation are analyzed.Then,the method is used to reduce the order of the high-order robust H∞loop shaping controller.Finally,the method is analyzed and verified by the simulations and experiments.The results show that by the reduced-order method of minimum implementation and balanced truncation,the stabilization precision of the robust H∞loop shaping controller is increased by about 10%.

Adenylate kinase phosphate energy shuttle underlies energetic communication in flagellar axonemes

The complexities of energy transfer mechanisms in the flagella of mammalian sperm flagella have been intensively investigated and demonstrate significant diversity across species.Enzymatic shuttles,particularly adenylate kinase(AK)and creatine kinase(CK),are pivotal in the efficient transfer of intracellular ATP,showing distinct tissue-and species-specificity.Here,the expression profiles of AK and CK were investigated in mice and found to fall into four subgroups,of which Subgroup III AKs were observed to be unique to the male reproductive system and conserved across chordates.Both AK8 and AK9 were found to be indispensable to male reproduction after analysis of an infertile male cohort.Knockout mouse models showed that AK8 and AK9 were central to promoting sperm motility.Immunoprecipitation combined with mass spectrometry revealed that AK8 and AK9 interact with the radial spoke(RS)of the axoneme.Examination of various human and mouse sperm samples with substructural damage,including the presence of multiple RS subunits,showed that the head of radial spoke 3 acts as an adapter for AK9 in the flagellar axoneme.Using an ATP probe together with metabolomic analysis,it was found that AK8 and AK9 cooperatively regulated ATP transfer in the axoneme,and were concentrated at sites associated with energy consumption in the flagellum.These findings indicate a novel function for RS beyond its structural role,namely,the regulation of ATP transfer.In conclusion,the results expand the functional spectrum of AK proteins and suggest a fresh model regarding ATP transfer within mammalian flagella.

Detection of composition of functional component theabrownins in Pu-erh tea by degradation method

Habitual tea consumption can reduce the risk of ASCVD morbidity and mortality and all-cause mortality in China,and long-term adherence to this habit can provide greater protection.Pu-erh tea is one of the representatives of post-fermented teas,and the polymers in Pu-erh tea have anti-cancer and anti-hyperlipidemic activities,but their chemical composition is still unknown.In this study,the chemical composition of Pu-erh tea was investigated in detail and eight(1–8)known compounds were isolated.The polymers in Pu-erh tea were also degraded by thiol degradation,and the fragments of quercetin and(–)-epicatechin-3-O-gallate were found in the thiol degradation products of Pu-erh tea polymers by UPLC observation and separation and purification.This is the first time that this fragment was obtained in Pu-erh tea polymer.

A green method for synthesizing novel nanoparticles and their application in flexible conductive patterns

A general and unified approach to synthesize Ag,Cu and Au nanoparticles(NPs)is developed at room temperature in air atmosphere under ultrasonication in poly(N-vinylpyrrolidone)(PVP)solutions with ascorbic acid and glucose as the reducing and nucleation agents,respectively.XRD,TEM,and HR-TEM analysis of the Ag,Cu,and Au NPs confirm purity and average diameters of 15.5±2.0 nm,50±3.0 nm,and 10±1.0 nm,respectively.An ultrasonic-assisted mechanism,wherein reduction occurs readily and produces anti-oxidation particles,is proposed and discussed.Fast infrared sintering was used to avoid damaging the substrate of conductive patterns whose resistivity at 10 W(~50℃)sintering power for less than 6 min reached up to 10±0.5 μΩ cm,40±3.0 μΩ cm,and 280±5 μΩ cm for Ag,Cu,and Au patterns,respectively.Paper-based electrodes were produced successfully and exhibited excellent flexibility and good conductivity.The potential of this method for large scale production is discussed.

中间包水模型数据的流出百分比分析方法

针对已有停留时间分布曲线或F曲线分析方法在归一化过程中,将单流中间包流出百分比或多流中间包中各流流出百分比之和限定为100%,将示踪剂流出总量信息掩盖,导致结果不精确的问题,本工作提出了流出百分比的分析方法,通过计算可以将物理实验结果转化为各流实时的流出百分比曲线。以流出百分比曲线为基础,计算得到时间加权平均方差和剩余示踪剂百分比,并以此对单流、四流中间包水模型实验结果进行分析。结果表明,采用流出百分比方法能对实验结果进行校对,进一步验证实验的可重复性。同时可对比双挡墙和U型挡墙控制装置设置下,四流中间包监测时间终点流出百分比差异及两倍理论停留时间时刻的死区比例大小。并可直观对比多流中间包不同挡墙下各流的一致性,及在单流堵塞后示踪剂在其他各流的分配及一致性。

High Capacity and Superior Rate Performances Coexisting in Carbon-Based Sodium-Ion Battery Anode

Amorphous carbon is considered as a prospective and serviceable anode for the storage of sodium.In this contribution,we illuminate the transformation rule of defect/void ratio and the restrictive relation between specifc capacity and rate capability.Inspired by this mechanism,ratio of plateau/slope capacity is regulated via temperature-control pyrolysis.Moreover,pore-forming reaction is induced to create defects,open up the isolated voids,and build fast ion channels to further enhance the capacity and rate ability.Numerous fast ion channels,high ion-electron conductivity,and abundant defects lead the designed porous hard carbon/Co_(3)O_(4) anode to realize a high specifc capacity,prolonged circulation ability,and enhanced capacity at high rates.Tis research deepens the comprehension of sodium storage behavior and proposes a fabrication approach to achieve high performance carbonaceous anodes for sodium-ion batteries.

The impacts of fabrication systems on 3D concrete printing building forms

Recently,3D concrete printing(3DCP)technology starts entering the market from factories and laboratories,contributing to the creation of new construction methods and architectural forms.However,since the technologies of most 3DCP institutions are independently developed,there is a lack of consensus in terms of construction methods and development approaches in the industry.In this paper,based on 423DCP architectural works completed in last five years,a quantitative analysis was made to evaluate the impacts of the fabrication system on 3DCP building forms.The paper introduced three criteria,including Workspace Index,Geometric Complexity Index,and Tectonic Prospect Index,analyzing and answering the discussions about"adopting in-situ printing or prefabrication","using gantry printers or robotic arms"from the perspective of architectural form.By analyzing specific construction methods and design strategies in these projects,the research summarized three development trends,"mobile equipment,algorithmic structure,and intelligent construction",which will affect the future development of 3DCP building forms.Finally,the paper discussed the advantages,limitations,and potential of four different 3DCP fabrication systems,expecting to point out the directions to further optimize each system and realize more diverse 3DCP buildings.

减刑、假释法律适用问题及深化改革建议

减刑制度、假释制度是我国法律规定的刑罚执行变更的重要制度,是宽严相济刑事政策在刑罚执行变更中的具体体现,具有激励罪犯改造的重要作用。但从减刑、假释制度的实践来看,两项制度远远没有发挥出有利于促进罪犯改造、加强监管、预防和减少重新犯罪的功能和作用,并且在实践中出现了许多问题,如行刑实践中各地执行减刑、假释的情况不规范、不统一,罪犯计分考核规定不够科学、严谨,减刑、假释的适用严重失衡,执法司法三部门的配合协调不够有力等,严重制约着减刑、假释制度功能和作用的发挥。因此,应当深化改革减刑、假释制度的适用:一是全面客观地评价减刑、假释制度;二是坚持以政治建设统领刑罚执行工作,坚决贯彻党中央关于减刑、假释改革的要求;三是要加强顶层设计,坚定不移地将刑罚执行改革进行到底。
