| 1 | Nutritional Status of Children during and post-Global Economic Crisis in China显示文摘Objective To describe the impact of the global economic crisis on the nutritional status of children in China during and after the crisis.Methods Data from 1990 to 2010 were sourced from the National Food and Nutrition Surveillance System.Approximately 16 000 children under 5 years old were selected using a stratified random cluster method from 40 surveillance sites.Anthropometric and hemoglobin measurements for children under 5 were conducted.Nutritional status was determined according to WHO child growth standards.Results Prevalence of underweight and stunting in children under 5 had a downward trend.Underweight prevalence was close to normal (less than 5%),with prevalence of stunting 12.6% in 2009 and 12.1% in 2010 in rural areas.Prevalence of stunting in infants under 6 months and 6‐12 months old in poorer rural areas increased from 5.7%‐9.1% and 6.7%‐12.5%,respectively,in 2008‐2009.This trend also continued post‐crisis in 2010.Prevalence of stunting in children left behind by mothers was 20%‐30% higher than in children the same age in general and poorer rural areas.Prevalence of anemia in children did not change in rural areas,but prevalence of anemia in all age groups increased in poorer rural areas,especially in children under 24 months old.Level reached 30%‐40% in 2009,and fluctuated in 2010.Conclusion The nutritional status of children under 5 was comparatively stable during and after the global economic crisis,attributable to the Chinese government's policy response.The nutritional status in poorer rural areas fluctuated in response to the economic crisis and,thus,relevant action and intervention must be taken immediately to help the most vulnerable population in poorer rural areas.A proper national nutritional strategy for children under 2 years old,including nutrition supplementation for pregnant women and in‐home fortification for complementary feeding,should be initiated. | CHEN ChunMing HE Wu WANG YuYing DENG LiNa JIA FengMei | 2011 | Biomedical and Environmental Sciences2011，24，4： | 22 |
| 2 | 7YSZ coating prepared by PS-PVD based on heterogeneous nucleation显示文摘Plasma spray-physical vapor deposition(PS-PVD) as a novel coating process based on low-pressure plasma spray(LPPS) has been significantly used for thermal barrier coatings(TBCs).A coating can be deposited from liquid splats, nano-sized clusters, and the vapor phase forming different structured coatings, which shows obvious advantages in contrast to conventional technologies like atmospheric plasma spray(APS) and electron beam-physical vapor deposition(EBPVD). In addition, it can be used to produce thin, dense, and porous ceramic coatings for special applications because of its special characteristics, such as high power, very low pressure, etc. These provide new opportunities to obtain different advanced microstructures, thus to meet the growing requirements of modern functional coatings. In this work, focusing on exploiting the potential of gas-phase deposition from PS-PVD, a series of 7 YSZ coating experiments with various process conditions was performed in order to better understand the deposition process in PS-PVD, where coatings were deposited on different substrates including graphite and zirconia. Meanwhile, various substrate temperatures were investigated for the same substrate. As a result, a deposition mechanism of heterogeneous nucleation has been presented showing that surface energy is an important influencing factor for coating structures. Besides, undercooling of the interface between substrate and vapor phase plays an important role in coating structures. | Ziqian DENG Xiaofeng ZHANG Kesong ZHOU Min LIU Chunming DENG Jie MAO Zhikun CHEN | 2018 | Chinese Journal of Aeronautics2018，31，4： | 10 |
| 3 | Mechanism of vertical crack formation in Yb_(2)SiO_(5) coatings deposited via plasma spray-physical vapor deposition显示文摘Plasma spray-physical vapor deposition(i.e.,PS-PVD)is a promising method for obtaining advanced environmental barrier coatings(EBCs).The EBCs must meet some requirements in the application,in which the thermal cycle performance affects the service lifetime.The preparation of artificial vertical cracks in Yb_(2)SiO_(5) coatings is an effective approach for meeting the requirements above because vertical cracks provide a strain tolerance.To clarify the formation mechanism of vertical cracks during the PSPVD,the effects of coating thickness and substrate temperature on the formation of vertical cracks were investigated.In addition,the interactions of spray powder and plasma flame during coating deposition were also characterized by optical spectroscopy.It is indicated that vertical cracks are formed due to a thermal expansion mismatch between Yb_(2)SiO_(5) and mullite coating,transient cooling after deposition and the nucleation of evaporated Yb_(2)SiO_(5) as well. | Xiaofeng Zhang Chao Wang Ruijun Ye Chunming Deng Xinghua Liang Ziqian Deng Shaopeng Niu Jinbing Song Guo Liu Min Liu Kesong Zhou Jian Lu Junli Feng | 2020 | Journal of Materiomics2020，6，1： | 6 |
| 4 | Reaction Mechanism and Thermal Insulation Property of Al-deposited 7YSZ Thermal Barrier Coating显示文摘To increase the performance and efficiency of thermal barrier coating(TBC), it is important to improve the thermal insulation property. In this work, a columnar Al film was deposited at the top of 7 wt% yttriastabilized zirconia(7YSZ) TBC by magnetron sputtering. A vacuum heat treatment was then carried out to improve the insulation property of Al-deposited TBC. Reaction mechanism of Al-Zr O2 system in Aldeposited TBC was studied by differential thermal analysis(DTA). The phase structures of the assprayed TBC, the Al-deposited and vacuum-treated TBC were characterized. The microstructure evolution of Al-deposited TBC was illustrated after vacuum heat treatment. And the insulation property of the assprayed TBC and treated TBC was compared. The results show that a multi-scaled layer, consisting of micron/nano structured α-Al2O3 and Al3 Zr grain was in situ synthesized at the top of 7YSZ coating via vacuum heat treatment. The TBC with the multi-scaled overlay has better insulation property than the assprayed TBC. | Xiaofeng Zhang Kesong Zhou Wei Xu Jinbing Song Chunming Deng Min Liu | 2015 | Journal of Materials Science & Technology2015，31，10： | 5 |
| 5 | Yttria-stabilized-zirconia hollow spheres prepared by atmospheric plasma spray显示文摘Yttria-stabilizecl-zirconia(YSZ) hollow spheres are widely utilized for their novel physical and chemical properties.However,developing a simple and low-cost method for preparing such hollow spheres still remains a great challenge.In this paper,an atmospheric plasma spray(APS) method is introduced,and the formation mechanism of hollow 7YSZ(ZrO_2-7wt%Y_2O_3) spheres is presented.The hollow sphere morphology was observed by scanning electron microscopy(SEM) when agglomerated and sintered 7YSZ powders were used.Additionally,additive composition changes,phase transformations,and the thermal behavior of 7YSZ powders were analyzed by energy dispersive spectroscopy(EDS),X-ray diffractometry(XRD),thermogravimetric analysis(TG) and differential scanning calorimeter analysis(DSC).Furthermore,the phase transformations of agglomerated and sintered 7YSZ powders,7YSZ hollow spheres that annealed at various temperatures for different times are analyzed. | Xiaofeng Zhang Kesong Zhou Fa Chang Chen Song Chunming Deng Siyuan Liang | 2014 | Particuology2014，12，3： | 4 |
| 6 | Genome of a citrus rootstock and global DNA demethylation caused by heterografting显示文摘Grafting is an ancient technique used for plant propagation and improvement in horticultural crops for at least 1,500 years.Citrus plants,with a seed-to-seed cycle of 5–15 years,are among the fruit crops that were probably domesticated by grafting.Poncirus trifoliata,a widely used citrus rootstock,can promote early flowering,strengthen stress tolerance,and improve fruit quality via scion–rootstock interactions.Here,we report its genome assembly using PacBio sequencing.We obtained a final genome of 303 Mb with a contig N50 size of 1.17Mb and annotated 25,680 protein-coding genes.DNA methylome and transcriptome analyses indicated that the strong adaptability of P.trifoliata is likely attributable to its special epigenetic modification and expression pattern of resistance-related genes.Heterografting by using sweet orange as scion and P.trifoliata as rootstock and autografting using sweet orange as both scion and rootstock were performed to investigate the genetic effects of the rootstock.Single-base methylome analysis indicated that P.trifoliata as a rootstock caused DNA demethylation and a reduction in 24-nt small RNAs(sRNAs)in scions compared to the level observed with autografting,implying the involvement of sRNA-mediated graft-transmissible epigenetic modifications in citrus grafting.Taken together,the assembled genome for the citrus rootstock and the analysis of graft-induced epigenetic modifications provide global insights into the genetic effects of rootstock–scion interactions and grafting biology. | Yue Huang Yuantao Xu Xiaolin Jiang Huiwen Yu Huihui Jia Chunming Tan Gang Hu Yibo Hu Muhammad Junaid Rao Xiuxin Deng Qiang Xu | 2021 | Horticulture Research2021，8，1： | 4 |
| 7 | Fabrication and Growing Kinetics of Highly Dispersed Gadolinium Zirconate Nanoparticles显示文摘Highly dispersed gadolinium zirconate(GZ)nanoparticles with fluorite structure were successfully synthesized by co-precipitation method,and their phase composition and microstructure,formation mechanism,and grain growth kinetics were investigated.The results suggest that the nanoparticles were obtained through hydroxide dehydration and solid phase reaction.High dispersion was accomplished by ethanol solvent to reduce the hydrogen bond and sodium dodecyl benzene sulfonate(SDBS)surfactant to increase the electrostatic repulsion between the nanoparticles.The grain growth activation energy of GZ powders calcined at lower temperature(<1200°C)is 86.5 kJ/mol(Ql),and the grain growth activation energy of GZ powders calcined at higher temperature(>1200°C)is 148.4 kJ/mol(Qh).The current study shows that the optimal process to synthesize dispersed GZ nanoparticles includes ethanol solvent,3 wt.%SDBS surfactant,and 1100°C as calcining temperature. | Renbo Zhu Jianpeng Zou Jie Mao Xiaofeng Zhang Chunming Deng Min Liu Wenlong Chen | 2019 | Research and Application of Materials Science2019，1，1： | 3 |
| 8 | Wuacanthus(Acanthaceae),a new Chinese endemic genus segregated from Justicia(Acanthaceae)显示文摘A new genus,Wuacanthus Y.F.Deng,N.H.Xia&H.Peng(Acanthaceae),is described from the Hengduan Mountains,China.Wuacanthus is based on Wuacanthus microdontus(W.W.Sm.)Y.F.Deng,N.H.Xia&H.Peng,originally published in Justicia and then moved to Mananthes.The new genus is characterized by its shrub habit,strongly 2-lipped corolla,the 2-lobed upper lip,3-lobed lower lip,2 stamens,bithecous anthers,parallel thecae with two spurs at the base,2 ovules in each locule,and the 4-seeded capsule.Phylogenetic analyses show that the new genus belongs to the Pseuderanthemum lineage in tribe Justicieae.Wuacanthus is closely related to Pseuderanthemum but differs from the latter by its shorter corolla tube and two minute spurs at the base of each anther-theca.W.microdontus is assessed with the status EN B2ab(iii)based on the IUCN Red List Categories and Criteria. | Yunfei Deng Chunming Gao Nianhe Xia Hua Peng | 2016 | Plant Diversity2016，38，6： | 3 |

| 10 | A novel computational framework for establishment of atomic mobility database directly from composition profiles and its uncertainty quantification显示文摘In this work,a novel computational framework for establishment of atomic mobility database directly from the experimental composition profiles and its uncertainty quantification was developed by merging the Bayesian inference with the Markov chain Monte Carlo algorithm into the latest version of the Hit DIC software.By treating the simulation of composition profiles with the composition-dependent coefficients as the forward problem,the inverse coefficient problem that provides the potential way to compute the atomic mobilities directly from composition profiles can be postulated.The values and uncertainties of the atomic mobility parameters of interest were assessed by means of Bayesian inference,where the composition profiles were consumed directly.Benchmark tests that consider the number of diffusion couples and the noise levels were conducted.Practical application of the current framework in determination of atomic mobility descriptions of fcc Ni-Ta and Ni-Al-Ta alloys was performed.Further discussion about the results of the benchmark tests and practical study case indicated that the present computational framework together with numbers of composition profiles from the multiple diffusion couples can help to establish the high-quality atomic mobility database of the target multicomponent alloys. | Jing Zhong Lijun Zhang Xiaoke Wu Li Chen Chunming Deng | 2020 | Journal of Materials Science & Technology2020，47，13： | 1 |

| 13 | Detecting HI Galaxies with Deep Neural Networks in the Presence of Radio Frequency Interference显示文摘In the neutral hydrogen(H I)galaxy survey,a significant challenge is to identify and extract the H I galaxy signal from the observational data contaminated by radio frequency interference(RFI).For a drift-scan survey,or more generally a survey of a spatially continuous region,in the time-ordered spectral data,the H I galaxies and RFI all appear as regions that extend an area in the time-frequency waterfall plot,so the extraction of the H I galaxies and RFI from such data can be regarded as an image segmentation problem,and machine-learning methods can be applied to solve such problems.In this study,we develop a method to effectively detect and extract signals of H I galaxies based on a Mask R-CNN network combined with the PointRend method.By simulating FAST-observed galaxy signals and potential RFI impact,we created a realistic data set for the training and testing of our neural network.We compared five different architectures and selected the best-performing one.This architecture successfully performs instance segmentation of H I galaxy signals in the RFI-contaminated time-ordered data,achieving a precision of 98.64%and a recall of 93.59%. | Ruxi Liang Furen Deng Zepei Yang Chunming Li Feiyu Zhao Botao Yang Shuanghao Shu Wenxiu Yang Shifan Zuo Yichao Li Yougang Wang Xuelei Chen | 2023 | Research in Astronomy and Astrophysics2023，23，11： | 0 |

| 15 | Al-modification for PS-PVD 7YSZ TBCs to improve particle erosion and thermal cycle performances显示文摘Plasma spray-physical vapor deposition(PS-PVD)as a novel process was used to prepare feather-like columnar thermal barrier coatings(TBCs).This special microstructure shows good strain tolerance and non-line-of-sight(NLOS)deposition,giving great potential application in aero-engine.However,due to serious service environment of aero-engine,particle erosion performance is a weakness for PS-PVD 7YSZ TBCs.As a solution,an Al-modification approach was proposed in this investigation.Through in-situ reaction of Al and ZrO2,anα-Al2O3 overlay can be formed on the surface of 7YSZ columnar coating.The results demonstrate that this approach can improve particle erosion resistance since hardness improvement of Al-modified TBCs.Meanwhile,as another important performance of thermal cycle,it has a better optimization with 350-cycle water-quenching,compared with the as-sprayed TBCs. | Xiaofeng ZHANG Ming LI Ao ZHANG Shuangquan GUO Jie MAO Chunming DENG Panpan WANG Changguang DENG Junli FENG Min LIU Kesong ZHOU Cheng LAI | 2022 | Journal of Advanced Ceramics2022，11，7： | 0 |
| 16 | Ductile and high strength Cu fabricated by solid-state cold spray additive manufacturing显示文摘In this work,pure Cu with excellent strength and ductility(UTS of 271 MPa,elongation to fracture of 43.5%,uniform elongation of 30%)was prepared using cold spray additive manufacturing(CSAM),realizing a breakthrough in the field.An in-depth investigation was conducted to reveal the microstructure evolution,strengthening and ductilization mechanisms of the CSAM Cu,as well as the single splats.The results show that the CSAM Cu possesses a unique heterogeneous microstructure with a bimodal grain structure and extensive infinitely circulating ring-mounted distribution of twinning.Based on the single splat observation,the entire copper particle forms a gradient nano-grained(GNG)structure after high-speed impact deposition.The GNG-structured single splat serves as a unit to build the heterogeneous microstructure with bimodal grain distribution during the successive deposition in CSAM.The results also show that CSAM can achieve synergistic strengthening and ductilization by controlling the grain refinement and dislocation density.This work provides potential for CSAM technique in manufacturing various metallic parts with the desired combination of high strength and good ductility without additional post-treatments. | Chaoyue Chen Yingchun Xie Shuo Yin Wenya Li Xiaotao Luo Xinliang Xie Ruixin Zhao Chunming Deng Jiang Wang Hanlin Liao Min Liu Zhongming Ren | 2023 | Journal of Materials Science & Technology2023，，3： | 0 |
