1Rhizospheric microbial communities are driven by Panax ginseng at different growth stages and biocontrol bacteria alleviates replanting mortality显示文摘The cultivation of Panax plants is hindered by replanting problems, which may be caused by plantdriven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased,whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages. Few microbial community, such as Luteolibacter, Cytophagaceae, Luteibacter, Sphingomonas,Sphingomonadaceae, and Zygomycota, were observed; the relative abundance of microorganisms, namely,Brevundimonas, Enterobacteriaceae, Pandoraea, Cantharellales, Dendryphion, Fusarium, and Chytridiomycota,increased in the soils of adult ginseng plants compared with those in the soils of 2-year-old seedlings. Bacillus subtilis 50-1, a microbial antagonist against the pathogenic Fusarium oxysporum, was isolated through a dual culture technique. These bacteria acted with a biocontrol efficacy of 67.8%. The ginseng death rate and Fusarium abundance decreased by 63.3% and 46.1%, respectively, after inoculation with B. subtilis 50-1. Data revealed that microecological degradation could result from ginseng-driven changes in rhizospheric microbial communities;these changes are associated with the different ages and developmental stages of ginseng plants. Biocontrol using microbial antagonists alleviated the replanting problem.Linlin Dong Jiang Xu Lianjuan Zhang Ruiyang Cheng Guangfei Wei He Su Juan Yang Jun Qian Ran Xu Shilin Chen 2018Acta Pharmaceutica Sinica B2018,8,2:27
2Integrated metabolomic and transcriptomic analyses revealed the distribution of saponins in Panax notoginseng显示文摘Panax notoginseng is famous for its important therapeutic effects. Saponins are bioactive compounds found in different parts and developmental stages of P. notoginseng plants. Thus, it is urgently to study saponins distribution in different parts and growth ages of P. notoginseng plants. In this study,potential biomarkers were found, and their chemical characteristic differences were revealed through metabolomic analysis. High-performance liquid chromatography data indicated the higher content of saponins(i.e., Rg1, Re, Rd, and Rb1) in the underground parts than that in the aerial parts. 20(S)-Protopanaxadiol saponins were mainly distributed in the aerial parts. Additionally, the total saponin content in the 3-year-old P. notoginseng plant(188.0 mg/g) was 1.4-fold higher than that in 2-year-old plant(130.5 mg/g). The transcriptomic analysis indicated the tissue-specific transcription expression of genes, namely, PnFPS, PnSS, PnSE1, PnSE2, and PnDS, which encoded critical synthases in saponin biosyntheses. These genes showed similar expression patterns among the parts of P. notoginseng plants.The expression levels of these genes in the flowers and leaves were 5.2 fold higher than that in the roots and fibrils. These results suggested that saponins might be actively synthesized in the aerial parts and transformed to the underground parts. This study provides insights into the chemical and genetic characteristics of P. notoginseng to facilitate the synthesis of its secondary metabolites and a scientific basis for appropriate collection and rational use of this plant.Guangfei Wei Linlin Dong Juan Yang Lianjuan Zhang Jiang Xu Feng Yang Ruiyang Cheng Ran Xu Shilin Chen 2018Acta Pharmaceutica Sinica B2018,8,3:13
3High-concentrate feeding upregulates the expression of inflammation-related genes in the ruminal epithelium of dairy cattle显示文摘Background: The objective of this study was to characterize the m RNA expression profile related to rumen epithelial inflammation through the in vivo and in vitro experiments. In the in vivo experiment, rumen papillae were col ected from four dairy cows adapted to either a 40 %(LC) or 70 %(HC) concentrate feeds for microarray analysis.Results: Results showed that 245 differentially expressed genes(DEGs) were detected in the cows fed the HC relative to the LC diet. The DEGs were first annotated, and results revealed that the expression of inflammationrelated genes, including IL-1β, IL-2, IL-22, CCL19, CCL8, CX3CR1, CXCL6, INHBE, LEPR, PRL, and TNFRSF9 found in the cytokine-cytokine receptor pathway were up-regulated in the HC-fed cows, indicating local inflammation in the rumen epithelium was triggered. The expression of IL-1β, IL-2, and IL-6 was further validated by q RT-PCR. To demonstrate whether there were relationships between cytokine m RNA expression and ruminal factors(p H and LPS),the isolated ruminal epithelial cells were cultured in vitro. Results showed that the m RNA expression of IL-1β, IL-2,IL-6, and IL-8 increased after the LPS treatment, while low-p H treatment elevated the m RNA expression of TNF-α,suggesting that low-p H coupled with higher levels of LPS in rumen of cows fed the HC may be mainly responsible for the triggered local ruminal inflammation.Conclusions: Our results indicate that ruminal local inflammation response might be triggered during HC feeding,and these findings also enhance the knowledge of rumen epithelial adaptation to HC at the molecular level.Ruiyang Zhang Weiyun Zhu Shengyong Mao 2016Journal of Animal Science and Biotechnology2016,7,4:11
4A Review of Rotating Stall in Vaneless Diffuser of Centrifugal Compressor显示文摘At present, off-design centrifugal compressor suffers from great instabilities, such as rotating stall and surge, which lead to work failure, strong pressure fluctuations, and violent vibrations of the entire system. One cause of these instabilities is the rotating stall occurring in vaneless diffuser. In this review, recent researches on rotating stall of vaneless diffuser in centrifugal compressor are reviewed, and its inductive mechanism and characteristic description are emphatically introduced. In vaneless diffuser, the rotating stall starts up and fully develops under non-design conditions with the characteristic of increasing pressure fluctuation amplitude. The negative effects of rotating stall include reverse flow and vortex, both of which have significant effects on the instability of centrifugal compressors. Some improvement methods of rotating stall are also introduced, and a lot of examples are given. Finally, some suggestions and discussions are put forward for the future work.ZHANG Lei HE Ruiyang WANG Songling ZHANG Qian 2020Journal of Thermal Science2020,29,2:6
5WFRFT modulation recognition based on HOC and optimal order searching algorithm显示文摘A hybrid carrier(HC) scheme based on weighted-type fractional Fourier transform(WFRFT) has been proposed recently.While most of the works focus on HC scheme's inherent characteristics, little attention is paid to the WFRFT modulation recognition.In this paper, a new theory is provided to recognize the WFRFT modulation based on higher order cumulants(HOC). First, it is deduced that the optimal WFRFT received order can be obtained through the minimization of 4 th-order cumulants, C_(42). Then, a combinatorial searching algorithm is designed to minimize C_(42).Finally, simulation results show that the designed scheme has a high recognition rate and the combinatorial searching algorithm is effective and reliable.LIANG Yuan DA Xinyu WU Jialiang XU Ruiyang ZHANG Zhe LIU Hujun 2018Journal of Systems Engineering and Electronics2018,29,3:6
62020 roadmap on pore materials for energy and environmental applications显示文摘Porous materials have attracted great attention in energy and environment applications,such as metal organic frameworks(MOFs),metal aerogels,carbon aerogels,porous metal oxides.These materials could be also hybridized with other materials into functional composites with superior properties.The high specific area of porous materials offer them the advantage as hosts to conduct catalytic and electrochemical reactions.On one hand,catalytic reactions include photocatalytic,p ho toe lectrocatalytic and electrocatalytic reactions over some gases.On the other hand,they can be used as electrodes in various batteries,such as alkaline metal ion batteries and electrochemical capacitors.So far,both catalysis and batteries are extremely attractive topics.There are also many obstacles to overcome in the exploration of these porous materials.The research related to porous materials for energy and environment applications is at extremely active stage,and this has motivated us to contribute with a roadmap on ’porous materials for energy and environment applications’.Zengxi Wei Bing Ding Hui Dou Jorge Gascon Xiang-Jian Kong Yujie Xiong Bin Cai Ruiyang Zhang Ying Zhou Mingce Long Jie Miao Yuhai Dou Ding Yuan Jianmin Ma 2019Chinese Chemical Letters2019,30,12:5
7Responsive changes of rumen microbiome and metabolome in dairy cows with different susceptibility to subacute ruminal acidosis显示文摘Subacute ruminal acidosis(SARA)represents one of the most important digestive disorders in intensive dairy farms,and dairy cows are individually different in the severity of SARA risk.The objectives of the current study were to investigate differences in the ruminal bacterial community and metabolome in dairy cattle with different susceptibility to SARA.In the present study,12 cows were initially enrolled in the experiment.Based on average ruminal pH,4 cows with the lowest ruminal pH were assigned to the susceptible group(SUS,pH=5.76,n=4)and 4 cows with the highest ruminal pH assigned to the tolerant group(TOL,pH=6.10,n=4).Rumen contents from susceptible(SUS,n=4)and tolerant(TOL,n=4)dairy cows were collected through rumen fistula to systematically reveal the rumen microbial and metabolic alterations of dairy cows with different susceptibility to SARA using multi-omics approaches(16S and 18S rRNA gene sequencing and metabolome).The results showed that despite being fed the same diet,SUS cows had lower ruminal pH and higher concentrations of total volatile fatty acids(VFA)and propionate than TOL cows(P<0.05).No significant differences were observed in dry matter intake,milk yield,and other milk compositions between the SUS and TOL groups(P>0.05).The principal coordinates analysis based on the analysis of molecular variance indicated a significant difference in bacterial composition between the two groups(P=0.01).More specifically,the relative abundance of starch-degrading bacteria(Prevotella spp.)was greater(P<0.05),while the proportion of fiber-degrading bacteria(unclassified Ruminococcaceae spp.,Ruminococcus spp.,Papillibacter,and unclassified Family_-XIII)was lower in the rumen of SUS cows compared with TOL cows(P<0.05).Community analysis of protozoa showed that there were no significant differences in the diversity,richness,and community structure(P>0.05).Metabolomics analysis revealed that the concentrations of organic acids(such as lactic acid),biogenic amines(such as histamine),and bacterial degradation products(such as hypoxanthine)were significantly higher in the SUS group compared to the TOL group(P<0.05).These findings revealed that the higher proportion of starch-degrading bacteria/lower fiber-degrading bacteria in the rumen of SUS cows resulted in higher VFA-producing capacity,in particular propionate.This caused a disruption in metabolic homeostasis in the rumen which might be the reason for the higher susceptibility to SARA.Overall,these findings enhanced our understanding of the ruminal microbiome and metabolic changes in cows susceptible to SARA.Tao Zhang Yingyu Mu Ruiyang Zhang Yanfeng Xue Changzheng Guo Wangpan Qi Jiyou Zhang Shengyong Mao 2022Animal Nutrition2022,,1:4
8Excellent tribological properties of epoxy-Ti3C2 with three-dimensional nanosheets composites显示文摘As a widely used engineering polymer,epoxy resin has been successfully employed in high-performance components and setups.However,the poor thermal and friction properties of traditional epoxy resin greatly limit its application in many extreme environments.In this work,a new kind of epoxy-Ti3C2 with three-dimensional nanosheets(3DNS)composite which was designed by freeze-drying method showed up excellent thermal and friction properties.As a result,the coefficient of thermal expansion(CTE)of epoxy-Ti3C23DNS 3.0 composites was 41.9 ppm/K at 40℃,which was lower than that of the traditional epoxy resin(46.7 ppm/K),and the thermal conductivity(TC)was also improved from 0.176 to 0.262 W/(m-K).Meanwhile,epoxy-Ti3C23DNS 1.0 composites showed up the best friction property,with wear rate 76.3%lower than that of epoxy resin.This work is significant for the research of high-performance composite materials.Fanning MENG Zhenyu ZHANG Peili GAO Ruiyang KANG Yash BOYJOO Jinhong YU Tingting LIU 2021Friction2021,9,4:3
9InP quantum dots on g-C_(3)N_(4) nanosheets to promote molecular oxygen activation under visible light显示文摘Largely limited by the high dissociation energy of the O—O bond,the photocatalytic molecular oxygen activation is highly challenged,which re strains the application of photocatalytic oxidation technology for atmospheric pollutants removal.Herein,we design and fabricate the InP QDs/g-C_(3)N_(4) compounds.The introduction of InP QDs promotes the charge transfer within the interface resulting in the effective separation of photo-generated carriers.Furthermore,InP QDs greatly facilitates the activation of molecular oxygen and promote the formation of O_(2)·under visible-light illuminatio n.These conclusions are identified by experimental and calculation results.Hence,NO can be combined with the O_(2)·to form O—O—N—O intermediate to direct conversion into NO_(3).As a result,the NO removal ratio of g-C_(3)N_(4) has a one fold increase after InP QDs loaded and the generation of NO_(2) is effectively inhibited.This wo rk may provide a strategy to design highly efficient materials for molecular oxygen activation.Yuehan Cao Qian Zheng Zhiqiang Rao Ruiyang Zhang Zhanghui Xie Shan Yu Ying Zhou 2020Chinese Chemical Letters2020,31,10:3

11Enhanced tribological properties of aligned graphene-epoxy composites显示文摘The random distribution of graphene in epoxy matrix hinders the further applications of grapheneepoxy composites in the field of tribology.Hence,in order to fully utilize the anisotropic properties of graphene,highly aligned graphene-epoxy composites(AGEC)with horizontally oriented structure have been fabricated via an improved vacuum filtration freeze-drying method.The frictional tests results indicated that the wear rate of AGEC slowly increased from 5.19x10^(-6)mm^(3)/(N-m)to 2.87x10^(-5)mm^(3)/(N-m)with the increasing of the normal load from 2 to 10 N,whereas the friction coefficient(COF)remained a constant of 0.109.Compared to the neat epoxy and random graphene-epoxy composites(RGEC),the COF of AGEC was reduced by 87.5%and 71.2%,and the reduction of wear rate was 86.6%and 85.4%at most,respectively.Scanning electron microscope(SEM)observations illustrated that a compact graphene self-lubricant film was formed on the worn surface of AGEC,which enables AGEC to possess excellent tribological performance.Finally,in light of the excellent tribological properties of AGEC,this study highlights a pathway to expand the tribological applications of graphene-epoxy composites.Yuefeng DU Zhenyu ZHANG Dong WANG Lezhen ZHANG Junfeng CUI Yapeng CHEN Mingliang WU Ruiyang KANG Yunxiang LU Jinhong YU Nan JIANG 2022Friction2022,10,6:2

13The Critical Role of Fillers in Composite Polymer Electrolytes for Lithium Battery显示文摘With excellent energy densities and highly safe performance,solidstate lithium batteries(SSLBs)have been hailed as promising energy storage devices.Solid-state electrolyte is the core component of SSLBs and plays an essential role in the safety and electrochemical performance of the cells.Composite polymer electrolytes(CPEs)are considered as one of the most promising candidates among all solid-state electrolytes due to their excellent comprehensive performance.In this review,we briefly introduce the components of CPEs,such as the polymer matrix and the species of fillers,as well as the integration of fillers in the polymers.In particular,we focus on the two major obstacles that affect the development of CPEs:the low ionic conductivity of the electrolyte and high interfacial impedance.We provide insight into the factors influencing ionic conductivity,in terms of macroscopic and microscopic aspects,including the aggregated structure of the polymer,ion migration rate and carrier concentration.In addition,we also discuss the electrode-electrolyte interface and summarize methods for improving this interface.It is expected that this review will provide feasible solutions for modifying CPEs through further understanding of the ion conduction mechanism in CPEs and for improving the compatibility of the electrode-electrolyte interface.Xueying Yang Jiaxiang Liu Nanbiao Pei Zhiqiang Chen Ruiyang Li Lijun Fu Peng Zhang Jinbao Zhao 2023Nano-Micro Letters2023,15,5:1
14Plasma-enhanced catalytic activation of CO_(2) in a modified gliding arc reactor显示文摘For the first time,this paper demonstrates a synergistic effect from the combination of a gliding arc discharge plasma with a photocatalyst TiO_(2) for CO_(2) dissociation.The effects of adding a tray downstream the discharge and the combination of the catalyst with plasma have been investigated.Two different combination modes of plasma catalysis,i.e.,in-plasma catalysis and post-plasma catalysis,have been evaluated with the emphasis on the analysis of potential mechanisms.The results show that modifying the gliding arc reactor by the addition of a tray can enhance the fraction of gas treated by plasma,thus improv-ing the reaction performance.An exceptional synergistic effect of combining the gliding arc discharge with TiO_(2) for CO_(2) activation forms in the in-plasma catalysis mode.The presence of TiO_(2) significantly enhances the CO_(2) conversion by 138% and the energy efficiency by 133%at a flow rate of 2 L/min.The plasma activation effect,which produces energetic electrons that can create the electron-hole pairs on the catalyst surface,is believed to be the major contributor to the generation of the plasma catalysis synergy.This mechanism has been further evidenced by the negligible influence of the post-plasma catalysis on the reaction performance.Hao Zhang Li Li Ruiyang Xu Jingying Huang Ni Wang Xiaodong Li Xin Tu 2020Waste Disposal and Sustainable Energy2020,2,2:1

16Investigation on the genetic-inconsistent paternity cases using the MiSeq FGx system显示文摘Mutations might challenge the paternity index calculation in forensic identification.While many studies have focussed on the autosomal short tandem repeats(A-STR),the mutation status of sex chromosomes and single nucleotide polymorphism(SNP)remain blank.Next generation sequencing(NGS),known as high throughput and large sequence polymorphism,is a promising tool for forensic genetics.To describe the mutation landscapes in the paternity cases with genetic inconsistencies,a total of 63 parentage confirmed paternity cases contained at least one mismatched locus have been collected.The mutations were subsequently evaluated using Verogen’s MPSForenSeqTM DNASignature Kit and a microsatellite instability(MSI)detection kit.The result showed 98.41%(62/63)of the cases had no additional autosomal mutations even when the number of A-STRs increased to 27.As for the sex chromosomes,about 11.11%(7/63)of the cases exhibited either X-STR or Y-STR mutations.D2S1338,FGAand Penta Ewere the most frequent altered STRs,which suggested they might be the mutation hotspots.In addition,a male with sex chromosome abnormality was observed accidently,whose genotype might be 47,XXY,rather than MSI.Nearly 56.90%of the STR loci possessed isoalleles,which might result in higher STR polymorphisms.No Mendelian incompatibility was detected among the SNP markers,which indicated that SNP was a more reliable genetic marker in the genetic-inconsistent paternity cases.Anqi Chen Ruiyang Tao Chengtao Li Suhua Zhang 2022Forensic Sciences Research2022,7,4:0

18Effect of Non-Convective Zone Thickness on Thermal Efficiency of Salt Gradient Solar Ponds显示文摘An improved radiation transmission and thermal efficiency model for solar ponds has been proposed based on both the Hull Model and Wang/Seyed-Yagoobi Model in this paper.The new model is more accurate to actual measured conditions because multiple reflections and turbidity effects are included.Absorption penetration,thermal conductivity loss and thermal efficiency under different Non-Convective Zone thicknesses are numerically analyzed and thoroughly discussed.The results show thatΔT/I0 plays a critical role for the thermal efficiency of solar pond.Furthermore,it is found through calculation that there is an optimum thickness of the Non-Convective Zone.When the Non-Convective Zone thickness is less than this critical threshold,both temperature and thermal efficiency are decreased with increasing turbidity.However,when the Non-Convective Zone thickness is greater than this critical threshold,the increasing turbidity within a certain range will be beneficial to improve the thermal efficiency of solar pond.In addition,optimum Non-Convective Zone thickness is also related to the temperature,turbidity,salinity variation and bottom reflectivity.Nan Li Ruiyang Xu Caihong Zhang Guoping Wu 2021Energy Engineering2021,118,4:0
19Monolithic polyimine vitrimer/graphene aerogel composites显示文摘Graphene-polymer composites have attracted great attention as sensing materials due to their tailorable electrical conductivity, physicochemical properties, and sensitivity to geometric and functional changes.Herein, we report the first example of cylindrical monolithic polyimine vitrimer/graphene composites with excellent mechanical, compressive, rehealable and recyclable, and piezoresistive properties via simple infiltration of polymer monomers into the pores of graphene aerogel followed by thermal curing. The composites exhibit excellent durable compressibility(negligible reduction in the compression properties even after 3000 consecutive compression cycles), rapid recovery to the original size upon stress released,high compressive strength(up to 1.2 MPa), and high conductivity(up to 79 S/m). Excellent piezoresistive properties were observed, displaying consistent and reliable change of the electrical resistance with the compression ratio. Furthermore, rehealing with ~100% recovery of the compressive strength and electric conductivity was achieved under mild rehealing conditions, which is highly desired but has rarely been reported for electronic materials. The facile strategy for fabrication of rehealable monolithic polymer/GAs can open new possibilities for the sustainable development of composites with high electrical conductivity for various applications such as sensing, health monitoring, and movement detection.Jinye Zhang Shichang Luo Yunlong Ma Ruiyang Li Yinghua Jin Li Qiu Wei Zhang 2023Chinese Chemical Letters2023,34,2:0
203D printed propeller-like metamaterial for wide-angle and broadband microwave absorption显示文摘It is a challenge to design an absorber which can simultaneously satisfy comprehensive demands of broad absorption band,wide incident angle range,and low-profile.In this work,we designed a metamaterial absorber(MMA)based on the antenna reciprocity theory to achieve the above goals.Firstly,a three-dimensional(3D)propeller-like structure with reference to a typical magneto-electric dipole(MED)an-tenna was proposed and analyzed by the characteristic mode(CM)theory to realize near-omnidirectional radiation.Then,the radiation-absorption conversion was realized by introducing lossy materials into this structure,and the absorption performance was further improved by optimizing the dispersion feature of the lossy materials.Finally,the propeller-like metamaterial absorber with a thickness of 0.113λL was manufactured efficiently and integrally through 3D printing technology.Simulation results showed that the proposed absorber can achieve broadband absorption with the efficiency more than 90%in the fre-quency band of 3.4-10 GHz.It also has excellent wide-angle absorption capacity,with Transverse Electric(TE)polarization of 0°to 50°and Transverse Magnetic(TM)polarization of 0°to 80°.With the increase of incident angle,the upper limit of absorption bandwidth can be gradually extended to 18 GHz.Moreover,the effectiveness in the range of 0°to 60°incident angle is verified by measuring the reflectivity of the 3D printed absorber.Ruiyang Tan Fangkun Zhou Yijie Liu Baoshan Zhang Yi Yang Jintang Zhou Ping Chen Tian Jiang 2023Journal of Materials Science & Technology2023,,13:0
