1Discussion on the Mechanism of Boric Acid and Phosphoric Acid to Improve the Hardening of Complex Calcium Lubricating Grease显示文摘In order to solve the hardening problem of complex calcium lubricating grease, the water absorption test of several calcium salts was carried out, and it was found that calcium 12-hydroxystearate did not absorb water, and calcium acetate, calcium phosphate and calcium borate had different degrees of water absorption. Calcium acetate has the highest water absorption rate, while calcium phosphate and calcium borate show comparable water absorption rates. Upon using the molecular simulation technology, it is found that in the complex calcium grease system, calcium phosphate and calcium borate tend to combine with water, which inhibits the water absorption of calcium acetate and alleviate the hardening problem.Zheng Hui Sun Hongwei He Yifeng Su Shuo Zhuang Minyang Liu Xinyang 2019China Petroleum Processing & Petrochemical Technology2019,21,4:3
2Preparation and Rheological Properties of Vacuum Lubricating Grease显示文摘A kind of vacuum lubricating grease was prepared by using perfluoropolyether as base oil,perfluorinated polymer as thickener,and self-made additives.The colloidal stability of the grease was greatly improved by introducing a colloidal structure modifier.The rheological properties of the self-made grease(SMG),such as viscosity versus time,thixotropy,etc.,were studied by a rheometer at different temperatures and were compared with those of foreign brand grease(FBG).The results show that the performance of SMG reached the level of similar FBG,and some properties such as mechanical stability,colloidal stability,extreme pressure and antiwear properties were better.It can be used for long life lubrication of moving parts in a vacuum environment.He Yifeng Sun Hongwei Liu Xinyang 2021China Petroleum Processing & Petrochemical Technology2021,23,1:3
3Experimental Study on the Heating Effect of a Wind-Energy Stirring Heater显示文摘In this paper,an experiment system of wind-energy stirring heater has been designed and built.Its heating performance under the rotation speed of 300 r/min has been studied through changing stirring rotor’s layer number or using different working fluids.With the help of CFD numerical simulation method,we studied the influence factors including temperature rise,total heat,heating power of each experimental group,and analyzed why these factors have such an effect.The results show:increasing the layer number of the stirring rotors can increase the motion intensity of working fluid and improve the heating effect;the quantity of effective working fluid in the rotor area can be increased significantly with the increasing of liquid level;the working liquid with high density,low viscosity,low specific heat capacity will be the ideal one.LIU Xingran SUN Xianpeng LI Jianming QIU Xinyang YANG Kang CAO Yanfei 2021Journal of Thermal Science2021,30,3:2
4Effect of cooked rice with added fructo-oligosaccharide on faecal microorganisms investigated by in vitro digestion and fermentation显示文摘In the present study,the effects of cooked rice(CR)with added fructo-oligosaccharide(FOS)on faecal flora were studied by a simulated in vitro digestion and fermentation method.The total carbohydrate content,p H,and s hort-chain fatty acids(SCFAs)were determined during in vitro digestion and fermentation.The change in the bacterial phase distribution after the fermentation was also analysed.The results showed that t he total carbohydrate content of the CR with added FOS(FCR)significantly decreased during the simulated digestion.Meanwhile,the p H of the FCR decreased and the SCFAs concentration increased significantly compared to those of the CR during the simulated fermentation.In addition,the FCR showed the advantage of promoting beneficial bacteria,such as Bifidobacterium and Lactobacillus,and inhibiting harmful bacteria,such as Bacteroides and Klebsiella compared to the CR.Therefore,the FOS as a prebiotic could be recommended to produce the high-quality healthy rice food.Fei Pei Wen Li Xiaolei Ni Xinyang Sun Yijun Yao Yong Fang Wenjian Yang Qiuhui Hu 2023Food Science and Human Wellness2023,12,2:2
5All-fiber spatiotemporal mode-locking lasers with large modal dispersion显示文摘It is a challenging problem to balance the modal walk-off(modal dispersion) between multiple transverse modes and chromatic dispersion in long step-index multimode fibers(MMFs). By properly designing the oscillator, we have overcome the difficulty and successfully obtained an all-fiber spatiotemporal mode-locked laser based on step-index MMFs with large modal dispersion for the first time, to our knowledge. Various proofs of spatiotemporal mode-locking(STML) such as spatial, spectral, and temporal properties, are measured and characterized.This laser works at a fundamental frequency of 28.7 MHz, and achieves a pulse laser with single pulse energy of 8 nJ, pulse width of 20.1 ps, and signal-to-noise ratio of-70 dB. In addition, we observe a dynamic evolution of the transverse mode energy during the STML establishment process that has never been reported before.Huaiwei Zhang Yunhong Zhang Jiying Peng Xinyang Su Xiaosheng Xia Dongjian Xu Junhao Chen Tianran Sun Kai Zheng Jianquan Yao Yi Zheng 2022Photonics Research2022,10,2:2
6Stress transfer around a broken fiber in unidirectional fiber-reinforced composites considering matrix damage evolution and interface slipping显示文摘A shear-lag model is applied to study the stress transfer around a broken fiber within unidirectional fiber-reinforced composites(FRC) subjected to uniaxial tensile loading along the fiber direction.The matrix damage and interfacial debonding,which are the main failure modes,are considered in the model.The maximum stress criterion with the linear damage evolution theory is used for the matrix.The slipping friction stress is considered in the interfacial debonding region using Coulomb friction theory,in which interfacial clamping stress comes from radial residual stress and mismatch of Poisson's ratios of constituents(fiber and matrix).The stress distributions in the fiber and matrix are obtained by the shear-lag theory added with boundary conditions,which includes force continuity and displacement compatibility constraints in the broken and neighboring intact fibers.The result gives axial stress distribution in fibers and shear stress in the interface and compares the theory reasonably well with the measurement by a polarized light microscope.The relation curves between damage,debonding and ineffective region lengths with external strain loading are obtained.YANG Zhong ZHANG BoMing ZHAO Lin SUN XinYang 2011Science China(Physics,Mechanics & Astronomy)2011,54,2:2

9ITO/Cu multilayer electrodes for high-brightness electrochromic displays显示文摘Fabry-Perot(F-P)nanocavity-type electrochromic devices with multicolor tunability have attracted significant interest in the past two years for their potential uses in a wide variety of applications,such as electronic display,military camouflage,and dynamic decoration.However,challenges such as insufficient brightness,lengthy switching times,and poor cycling stability have yet to be overcome.Herein,we demonstrate electrochromic electrodes based on ITO/Cu as both the current collector and the reflective layer,with WO_(3 )as the electrochromic material,forming a unique three-layered structure.The constituted WO_(3 )/ITO/Cu films present a high brightness value of about 84%before coloration,and a decent brightness value of 48%after coloration at−0.8​V.Moreover,a fast switching time between different coloration states(tc​=​2.2​s;tb​=​1​s)is recorded,attributed to the extremely low sheet resistivity of the ITO/Cu current collector.The films also reveal excellent electrochemical cycling stability across 2000 cycles.Xueqing Tang Zishou Hu Zhen Wang Jian Chen Xinyang Mu Ge Song Peiyan Sun Zhengji Wen Jiaming Hao Shan Cong Zhigang Zhao 2022eScience2022,2,6:1

12Surface Modified TiO2 Nanoparticles-an Effective Anti-wear and Anti-friction Additive for Lubricating Grease显示文摘The surface modified TiO_2 nanoparticles were prepared by using 12-hydroxystearic acid chemically modified on the TiO_2 surface. The average size of the TiO_2 particles is about 30 nm. The optimum ratio of tetrabutyl titanate to 12-hydroxystearic acid was 1/0.5. The bonding form between 12-hydroxystearic acid and TiO_2 nucleus was investigated by FTIR, DSC, TGA and XRD techniques. The lubricating grease containing the surface modified TiO_2 nanoparticles possesses excellent anti-wear and anti-friction properties. Compared with the grease without TiO_2, the PB value can be increased by 52% as the best performance of the grease containing surface modified TiO_2 nanoparticles, while the friction coefficient can be reduced by 33% with the addition of a small amount of TiO_2 nanoparticles, and meanwhile the wear scar diameter decreases by 25%.Li Yi Liu Xinyang Liu Dajun Sun Hongwei 2017China Petroleum Processing & Petrochemical Technology2017,19,2:1
13Flexible, self-cleaning, and high-performance ceramic nanofiber-based moist-electric generator enabled by interfacial engineering显示文摘Due to their long-term stability, even under extreme conditions, oxide ceramics have attracted significant attention in emerging fields like moist-electric generation. However, the inherent brittleness and low voltage output of oxide ceramic-based moistelectric generators(MEGs) limit their applications in wearable electronics. Herein, a facile strategy involving the combination of sol-gel electrospinning and calcination is used to fabricate flexible and freestanding Ti O_(2)/Zr O_(2)(TZ) composite nanofiber-based MEGs. The excellent flexibility of the TZ nanofiber membranes can be attributed to the suppression of their crystal structure transformation, dispersion of stress concentration, and reduction of crack propagation via interfacial engineering. The porous structure of the electrospun nanofiber membrane features an abundance of charged narrow channels for the diffusion of water molecules and generates a streaming potential. The optimal voltage output reached ~0.8 V, which is the highest value reported for an oxide ceramic-based MEG. Furthermore, the as-fabricated nanofiber-based MEG exhibits good self-cleaning capability to degrade organic pollutants under ultraviolet irradiation. By integrating mechanical flexibility, high performance, and a selfcleaning effect, this work presents a new idea for exploring diverse, efficient, and wearable oxide ceramic-based MEGs.WANG LiMing FENG LanLan SUN Zhao Yang HE XinYang WANG RongWu QIN XiaoHong YU JianYong 2022Science China(Technological Sciences)2022,65,2:1

15Differential transcriptomic landscapes of multiple organs from SARS-CoV-2 early infected rhesus macaques显示文摘SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries,how-ever,the underlying mechanism,in particular immune responses in different organs,remains elusive.In this study,comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed.Compared to normal controls,SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs,with drastic transcriptomic changes in cerebral cortex and right ventricle.Intriguingly,cerebral cortex exhibited a hyperinflammatory state evidenced by sig-nificant upregulation of inflammation response-related genes.Meanwhile,expressions of coagulation,angio-genesis and fibrosis factors were also up-regulated in cerebral cortex.Based on our findings,neuropilin 1(NRP1),a receptor of SARS-CoV-2,was significantly elevated in cerebral cortex post infection,accompanied by active immune response releasing inflammatory factors and signal transmission among tissues,which enhanced infection of the central nervous system(CNS)in a positive feedback way,leading to viral encephalitis.Overall,our study depicts a multi-tissue/organ tran-scriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2,and provides important insights into the mechanistic basis for COVID-19-asso-ciated clinical complications.Chun-Chun Gao Man Li Wei Deng Chun-Hui Ma Yu-Sheng Chen Yong-Qiao Sun Tingfu Du Qian-Lan Liu Wen-Jie Li Bing Zhang Lihong Sun Si-Meng Liu Fengli Li Feifei Qi Yajin Qu Xinyang Ge Jiangning Liu Peng Wang Yamei Niu Zhiyong Liang Yong-Liang Zhao Bo Huang Xiao-Zhong Peng Ying Yang Chuan Qin Wei-Min Tong Yun-Gui Yang 2022Protein & Cell2022,13,12:1

17Thermal Stress and Assembling Parameters Evolution of CMC Bolted Joint under Transient Thermal Loads显示文摘Ceramic matrix composite(CMC) and superalloy bolted joints have exhibited great potential for high temperature hot structure application in hypersonic aircraft. In service conditions, the thermal expansion mismatch between CMC and superalloy plates will cause complex thermal stress and strain distributions at hole-edge areas and assembly parameters changes of the joints under elevated temperatures. These effects might lead to early damage of joint structure, which will endanger the structural integrity and load carrying capacity of aircraft components. In the present study, transient heat transfer and thermo-structural analysis of C/SiC composite and superalloy bolted joint were carried out by using a commercial FEA software ABAQUS. The stress distributions at hole-edge areas, pre-load loosening, and variation of bolt-hole clearance of CMC bolted joints under transient temperature rises were discussed for better understanding of high temperature structural behaviors. Results showed that pre-load declined with the increase of imposed hot side temperature, due to the thermal expansion mismatch between CMC and superalloy. The bolt-hole clearance for the composite plate decreased, whereas the clearance for the superalloy plate increased with the rise of temperature.Shuyuan Zhao Zhengyu Li Zeliang Pu Xinyang Sun Wenjiao Zhang 2021Journal of Harbin Institute of Technology(New Series)2021,28,3:0
18Influence of Assembly Parameters on Tensile Behavior of Hybrid CMC and Superalloy Bolted Joints by Progressive Damage Analysis显示文摘With the considerable applications of ceramic matrix composites(CMC) in aircraft engineering, the design of CMC bolted joint gains paramount attention because of its capacity to to improve load-bearing efficiency of aircraft key structure. In this work, a 3 D finite element model was established to predict tensile performance and failure modes of single-lap, single-bolt 2 D C/SiC composite, and superalloy joint, which considers the progressive damage behavior of 2 D woven C/SiC composites. On the basis of the developed progressive damage model, a parametric study was carried out to illustrate the effects of bolt preload and bolt-hole clearance on mechanical behaviors of the hybrid bolted joint. It was found that the increase in the value of bolt preload made the failure load grow first and then drop, and the optimum value of bolt preload 5.00 kN generated 56.47% rise in the initial failure load and 22.83% rise in the final failure load for the bolted joint in comparison with zero preload case. As the clearance increased from 0 to 2.00%, the initial and final failure loads respectively declined by 45.88% and 24.02% for 2.00% bolt-hole clearance relative to the neat-fit case. The loss in failure loads can be reduced to compressive stress concentration around the fastening hole-edge area, leading to the appearance of earlier damages by the introduction of increasing bolt hole clearance.Chao Lv Feng Li Shuyuan Zhao Qian Sun Mingrui Li Xinyang Sun 2021Journal of Harbin Institute of Technology(New Series)2021,28,3:0
19Understanding water conservation vs. prof ligation traits in vegetable legumes through a physio-transcriptomic-functional approach显示文摘Abstract Vegetable soybean and cowpea are related warm-season legumes showing contrasting leaf water use behaviors under similar root drought stresses,whose mechanisms are not well understood.Here we conducted an integrative phenomic-transcriptomic study on the two crops grown in a feedback irrigation system that enabled precise control of soil water contents.Continuous transpiration rate monitoring demonstrated that cowpea used water more conservatively under earlier soil drought stages,but tended to maintain higher transpiration under prolonged drought.Interestingly,we observed a soybean-specific transpiration rate increase accompanied by phase shift under moderate soil drought.Time-series transcriptomic analysis suggested a dehydration avoidance mechanism of cowpea at early soil drought stage,in which the VuHAI3 and VuTIP2;3 genes were suggested to be involved.Multifactorial gene clustering analysis revealed different responsiveness of genes to drought,time of day and their interactions between the two crops,which involved species-dependent regulation of the circadian clock genes.Gene network analysis identified two co-expression modules each associated with transpiration rate in cowpea and soybean,including a pair of negatively correlated modules between species.Module hub genes,including the ABA-degrading gene GmCYP707A4 and the trehalose-phosphatase/synthase gene VuTPS9 were identified.Intermodular network analysis revealed putative co-players of the hub genes.Transgenic analyses verified the role of VuTPS9 in regulating transpiration rate under osmotic stresses.These findings propose that species-specific transcriptomic reprograming in leaves of the two crops suffering similar soil drought was not only a result of the different drought resistance level,but a cause of it.Pingping Fang Ting Sun Arun Kumar Pandey Libo Jiang Xinyang Wu Yannan Hu Shiping Cheng Mingxuan Li Pei Xu 2023Horticulture Research2023,10,3:0
20Dual-single-atoms of Pt-Co boost sulfur redox kinetics for ultrafast Li-S batteries显示文摘Applications of lithium-sulfur(Li-S)batteries are still limited by the sluggish conversion kinetics from polysulfide to Li_(2)S.Although various single-atom catalysts are available for improving the conversion kinetics,the sulfur redox kinetics for Li-S batteries is still not ultrafast.Herein,in this work,a catalyst with dual-single-atom Pt-Co embedded in N-doped carbon nanotubes(Pt&Co@NCNT)was proposed by the atomic layer deposition method to suppress the shuttle effect and synergistically improve the interconversion kinetics from polysulfides to Li_(2)S.The X-ray absorption near edge curves indicated the reversible conversion of Li_(2)Sx on the S/Pt&Co@NCNT electrode.Meanwhile,density functional theory demonstrated that the Pt&Co@NCNT promoted the free energy of the phase transition of sulfur species and reduced the oxidative decomposition energy of Li_(2)S.As a result,the batteries assembled with S/Pt&Co@NCNT electrodes exhibited a high capacity retention of 80%at 100 cycles at a current density of 1.3 mA cm^(−2)(S loading:2.5 mg cm^(−2)).More importantly,an excellent rate performance was achieved with a high capacity of 822.1 mAh g^(−1) at a high current density of 12.7 mA cm^(−2).This work opens a new direction to boost the sulfur redox kinetics for ultrafast Li-S batteries.Hanyan Wu Xuejie Gao Xinyang Chen Weihan Li Junjie Li Lei Zhang Yang Zhao Ming Jiang Runcang Sun Xueliang Sun 2024Carbon Energy2024,6,3:0
