| 2 | Room temperature liquid metal:its melting point,dominating mechanism and applications显示文摘The room temperature liquid metal(LM)is recently emerging as a new class of versatile materials with fascinating characteristics mostly originated from its simultaneous metallic and liquid natures.The melting point is a typical parameter to describe the peculiarity of LM,and a pivotal factor to consider concerning its practical applications such as phase change materials(PCMs)and advanced thermal management.Therefore,the theoretical exploration into the melting point of LM is an essential issue,which can be of special value for the design of new LM materials with desired properties.So far,some available strategies such as molecular dynamics(MD)simulation and classical thermodynamic theory have been applied to perform correlative analysis.This paper is primarily dedicated to performing a comprehensive overview regarding typical theoretical strategies on analyzing the melting points.It,then,presents evaluations on several factors like components,pressure,size and supercooling that may be critical for melting processes of liquid metal.After that,it discusses applications associated with the characteristic of low melting points of LM.It is expected that a great many fundamental and practical works are to be conducted in the coming future. | Junheng FU Chenglin ZHANG Tianying LIU Jing LIU | 2020 | Frontiers in Energy2020，14，1： | 3 |
| 3 | Effects of ZrO_2 Nanoparticles on the Microstructure and Thermal-protective Properties of PEO Coating on Al-12.5%Si Alloy显示文摘PEO ceramic coatings including ZrO_2-Al_2O_3-SiO_2 in three phases were prepared on an Al-12.5%Si alloy in electrolyte solutions containing ZrO_2 nanoparticles. The microstructures and phases of the coatings were analyzed by SEM and XRD, and the heat insulation performance and the thermal shock resistance of the coatings were investigated. The compactness of the coating increased significantly and the hindrance of the Si element on plasma electrolytic oxidation process was effectively weakened. The growth rate of the coating was improved substantially with the addition of ZrO_2 nanoparticles. The PEO ceramic coatings are primarily composed of SiO_2 and high temperature steady phases such as a-Al_2O_3 and c-ZrO_2. Both the content of c-ZrO_2 and the heat-insulating property of the coating increased significantly. The ceramic coatings with special microstructure and composition formed in the solutions containing ZrO_2 nanoparticles possess excellent heat insulation performance and thermal shock resistance. | 王萍 HAN Jing YAN Junheng WANG Jiandong | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，1： | 3 |

| 5 | Effects of rotor and stator geometry on dissolution process and power consumption in jet-flow high shear mixers显示文摘The jet-flow high shear mixer(JF-HSM)is a new type of intensified equipment with special configurations of the rotor and the stator.The mass transfer property and power consumption were studied in the solid-liquid system for a series of JF-HSMs involving different configuration parameters,such as rotor diameter,rotor blade inclination,rotor blade bending direction,stator diameter,and stator bottom opening diameter.The flow characteristics were examined by computational fluid dynamic simulations.Results indicate that the turbulent power consumption of the JF-HSM is affected by the change in rotor blade inclination and stator bottom opening.With the increase in the shear head size and the change in the rotor into a backward-curved blade,the solid-liquid mass transfer rate can be remarkably increased under the same input power.Dimensionless correlations for the mass transfer coefficient and power consumption were obtained to guide the scale-up design and selection of such a new type of equipment to intensify the overall mixing efficiency. | Lin Yang Wenpeng Li Junheng Guo Wei Li Baoguo Wang Minqing Zhang Jinli Zhang | 2021 | Frontiers of Chemical Science and Engineering2021，15，2： | 2 |

| 7 | Liquid metal hydraulics paradigm:Transmission medium and actuation of bimodal signals显示文摘In this article,room temperature gallium-based fluids(RTGFs)with unique thermal and conductive properties are proposed as a transmission fluid for the force carrying medium of hydraulics,which rectify the lack of the multi-functional hydraulic roles of liquid metal(LM).The typical physical properties of RTGFs and comparative conventional hydraulic fluids(commercial hydraulic oil and deionized water),such as thermal stability and rheological characteristics,are evaluated.Experimental and numerical methods,then,were adopted to clarify the force transmission performance of RTGFs and commercial hydraulic oils,as well as the influence of temperature fields on the viscosity of fluids.The results disclosed that the advantages of inherent flame resistance,wide liquid temperature range,and the viscosity changing slightly with temperature made RTGFs potential in finding efficient application in the hydraulics as new working fluids.Finally,for illustration,the rigid and flexible actuators driven by RTGFs were designed as hydraulic fluid and demonstrated their capabilities in grasping objects with various shapes and weights,respectively.And the tunable stiffness of such a flexible actuator was enabled via the solid-liquid phase change of LM.Additionally,a frequency-adjustable antenna was manufactured and showcased owing to the introduced transformable electromagnetic behaviors of LM.Overall,the gallium-based LM fluids with thermoelectrical and mechanical multimodal signal medium would serve as a potential candidate for future complex multifunctional signal transmission systems. | FU JunHeng GAO JianYe QN Peng LI DongDong YU DeHai SUN Peng HE ZhiZhu DENG ZhongShan LIU Jing | 2022 | Science China(Technological Sciences)2022，65，1： | 1 |

| 11 | Accumulation, transportation, and distribution of tetracycline and cadmium in rice显示文摘Co-exposure to heavy metal and antibiotic pollution might result in complexation and synergistic interactions,affecting rice growth and further exacerbating pollutant enrichment.Therefore,our study sought to clarify the influence of different Tetracycline (TC) and Cadmium(Cd) concentration ratios (both alone and combined) on rice growth,pollutant accumulation,and transportation during the tillering stage in hydroponic system.Surprisingly,our findings indicated that the interaction between TC and Cd could alleviate the toxic effects of TC/Cd on aerial rice structures and decrease pollutant burdens during root elongation.In contrast,TC and Cd synergistically promoted the accumulation of TC/Cd in rice roots.However,their interaction increased the accumulation of TC in roots while decreasing the accumulation of Cd when the toxicant doses increased.The strong affinity of rice to Cd promoted its upward transport from the roots,whereas the toxic effects of TC reduced TC transport.Therefore,the combined toxicity of the two pollutants inhibited their upward transport.Additionally,a low concentration of TC promoted the accumulation of Cd in rice mainly in the root tip.Furthermore,a certain dose of TC promoted the upward migration of Cd from the root tip.Laser ablation-inductively coupled plasma mass spectrometry demonstrated that Cd mainly accumulated in the epidermis and stele of the root,whereas Fe mainly accumulated in the epidermis,which inhibited the absorption and accumulation of Cd by the rice roots through the generation of a Fe plaque.Our findings thus provide insights into the effects of TC and Cd co-exposure on rice growth. | Chunfeng He Jini Zhou Chen Yang Zhiyi Song Junheng He Ziqing Huang Yurong Deng Jinling Wang Yu Xiong Zhi Dang | 2023 | Journal of Environmental Sciences2023，，4： | 1 |

| 13 | Martensitic twinning transformation mechanism in a metastable IVB element-based body-centered cubic high-entropy alloy with high strength and high work hardening rate显示文摘Realizing high work hardening and thus elevated strength–ductility synergy are prerequisites for the practical usage of body-centered-cubic high entropy alloys(BCC-HEAs).In this study,we report a novel dynamic strengthening mechanism,martensitic twinning transformation mechanism in a metastable refractory element-based BCC-HEA(TiZrHf)Ta(at.%)that can profoundly enhance the work hardening capability,leading to a large uniform ductility and high strength simultaneously.Different from conventional transformation induced plasticity(TRIP)and twinning induced plasticity(TWIP)strengthening mechanisms,the martensitic twinning transformation strengthening mechanism combines the best characteristics of both TRIP and TWIP strengthening mechanisms,which greatly alleviates the strengthductility trade-off that ubiquitously observed in BCC structural alloys.Microstructure characterization,carried out using X-ray diffraction(XRD)and electron back-scatter diffraction(EBSD)shows that,upon straining,α”(orthorhombic)martensite transformation,self-accommodation(SA)α”twinning and mechanicalα”twinning were activated sequentially.Transmission electron microscopy(TEM)analyses reveal that continuous twinning activation is inherited from nucleating mechanical{351}type I twins within SA“{351}”<■11>typeⅡtwinnedα”variants on{351}twinning plane by twinning transformation through simple shear,thereby accommodating the excessive plastic strain through the twinning shear while concurrently refining the grain structure.Consequently,consistent high work hardening rates of 2–12.5 GPa were achieved during the entire plastic deformation,leading to a high tensile strength of 1.3 GPa and uniform elongation of 24%.Alloy development guidelines for activating such martensitic twinning transformation strengthening mechanism were proposed,which could be important in developing new BCC-HEAs with optimal mechanical performance. | Yuhe Huang Junheng Gao Vassili Vorontsov Dikai Guan Russell Goodall David Dye Shuize Wang Qiang Zhu W.Mark Rainforth Iain Todd | 2022 | Journal of Materials Science & Technology2022，，29： | 1 |

| 16 | Comparative Transcriptome Analysis between Cytoplasmic Male-sterile Line and Its Maintainer During the Floral Bud Development of Pepper显示文摘The male-sterile line has been largely used in the hybrid seed production of pepper, which can effectively improve the efficiency of hybrid seed production. However, the formation mechanism of male sterility in pepper remains unclear. In the present study, we compared the gene expression patterns between pepper cytoplasmic male sterile line 9704 A and its maintainer 9704 B during floral bud development using RNA sequencing technology. A total of 547 976 and 2 416 Differentially Expressed Genes(DEGs) were identified in the stage S1, S2 and S3, respectively,and more than 70% of the DEGs were down-regulated in the sterile line. Gene Ontology(GO), and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were performed to further understand the functions of these identified DEGs. The results showed that the DEGs were mainly enriched in pathways of starch and sucrose metabolism, pentose and glucuronate interconversions. A number of genes, such as MS1, PME5, ATPB, and lots of transcription factors were found down-regulated in the sterile line, and we also identified a series of genes with large differences in expression patterns between sterile line and maintainer line. Collectively, our findings laid a foundation for further molecular breeding in pepper and provided new insights into its mechanism underlying the male sterility. | Junheng Lv Zhoubin Liu Yuhua Liu Lijun Ou Minghua Deng JingWang Jingshuang Song Yanqing Ma Wenchao Chen Zhuqing Zhang Xiongze Dai Xuexiao Zou | 2020 | Horticultural Plant Journal2020，6，2： | 1 |

| 18 | Micromixing performance of the teethed high shear mixer under semi-batch operation显示文摘Semi-batch operated reaction processes are necessary for some competitive reaction systems to achieve a desirable process selectivity and productivity of fine chemical products.Herein the structural and operating parameters of the teethed high shear mixers were adjusted to study the micromixing performance in the semi-batch operated system,using the Villermaux/Dushman reaction system.The results indicate that the rising of the rotor speed and the number of rotor teeth,the decrease of the width of the shear gap and the radial distance between the feed position and the inner wall of stator can enhance the micromixing level and lead to the decrease of the segregation index.Additionally,computational fluid dynamics calculations were carried out to disclose the evolution of the flow pattern and turbulent energy dissipation rate of the semi-batch operated high shear mixer.Furthermore,the correlation was established with a mean relative error of 8.05%and R^(2)of 0.955 to fit the segregation index and the parameters studied in this work,which can provide valuable guidance on the design and optimization of the semi-batch operated high shear mixers in practical applications. | Xiaoning Li Lin Yang Junheng Guo Wei Li Mingliang Zhou Jinli Zhang | 2022 | Frontiers of Chemical Science and Engineering2022，16，4： | 0 |
| 19 | A novel single-base mutation in CaSGR1 confers the stay-green phenotype in pepper显示文摘The stay-green trait is of considerable importance in extending the shelf life of green pepper fruit(Capsicum annuum L.)and in enhancing the appearance of ornamental plants.The study revealed the genetic and regulatory mechanisms of the stay-green trait in pepper,which will aid in the selection of ornamental pepper varieties.In this study,a pepper mutant with stay-green fruit named TNX348 was identified from a germplasm resource bank.Two segregating populations were constructed using the stay-green mutant TNX348 and then used in bulked segregant analysis combined with RNA sequencing and linkage analyses.The causal gene of the stay-green trait was mapped to an approximately 131-kb region,and a senescence-induced chloroplast protein gene,CaSGR1(Capana01g000359),was identified as a candidate gene.Sequencing analysis revealed a G→A single-base mutation of CaSGR1 in TNX348 that led to early termination of translation.Based on the single-base mutation,a single nucleotide polymorphism(SNP)marker co-segregating with the stay-green trait was developed.Furthermore,in transcriptome analysis,expression patterns of 11 hormone transduction-related transcription factors,such as abscisic acid-insensitive(ABI),abscisic acidresponsive element-binding factor(ABF),and NAC transcription factor,were similar or opposite to that of CaSGR1.The results indicated that the transcription factors might mediate chlorophyll degradation by regulating the expression of CaSGR1. | Yuhua Liu Lijun Ou Zhoubin Liu Junheng Lyu JingWang Jingshuang Song Bozhi Yang Wenchao Chen Sha Yang Wei Liu Xuexiao Zou Zhuqing Zhang | 2023 | Horticultural Plant Journal2023，9，2： | 0 |
| 20 | Hydrodynamic Pattern in Drying Saline Droplet with Suspended Nanoparticles显示文摘Evaporation of multicomponent droplets has gained much attention nowadays because of their complex flow fields and various deposition patterns.Here we observe strong flows in evaporating sodium chloride saline droplets with suspended alumina oxide nanoparticles.The evolution of flow pattern was studied by tracking the trajectories of particles and the velocity field was investigated with Particle Image Velocimetry analysis.The non-uniform evaporation rate along the droplet surface leads to a concentration gradient which induces the convection flow.During the evaporation process before crystallization happens,evolution of the flow can be divided into two regimes.In Regime I,a centrosymmetric convection recirculation is formed gradually.In RegimeⅡ,the convection recirculation migrates to the droplet edge and evolves into several small vortexes.At the late evaporation stage,crystallization could induce strong convection flows.It is shown that the flow tends to become more chaotic with a lower salt concentration. | Junheng Ren Xin Zhong Lu Shen Fei Duan | 2020 | Journal of Bionic Engineering2020，17，4： | 0 |
