| 1 | Performance of a completely autotrophic nitrogen removal over nitrite process for treating wastewater with different substrates at ambient temperature显示文摘The stability and parameters of a bio-ceramic filter for completely autotrophic nitrogen removal were investigated.The completely autotrophic nitrogen removal over nitrite(CANON) reactor was fed with different concentrations of ammonia(400,300,and 200mg N/L) but constant influent ammonia load.The results showed that the CANON system can achieve good treatment performance at ambient temperature(15-23°C).The average removal rate and removal loading of NH4+-N and TN was 83.90%,1.26kg N/(m3·day),and 70.14%,1.09kg N/(m3·day),respectively.Among the influencing factors like pH,dissolved oxygen and alkalinity,it was indicated that the pH was the key parameter of the performance of the CANON system.Observing the variation of pH would contribute to better control of the CANON system in an intuitive and fast way.Denaturing gradient gel electrophoresis analysis of microorganisms further revealed that there were some significant changes in the community structure of ammonium oxidizing bacteria,which had low diversity in different stages,while the species of anaerobic ammonium oxidizing(anammox) bacteria were fewer and the community composition was relatively stable.These observations showed that anaerobic ammonia oxidation was more stable than the aerobic ammonia oxidation,which could explain that why the CANON system maintained a good removal efficiency under the changing substrate conditions. | Xiaoyan Chang Dong Li Yuhai Liang Zhuo Yang Shaoming Cui Tao Liu Huiping Zeng Jie Zhang | 2013 | Journal of Environmental Sciences2013，25，4： | 12 |
| 2 | 3D C_f/SiBCN composites prepared by an improved polymer infiltration and pyrolysis显示文摘Using liquid poly(methylvinyl)borosilazanes(PMVBSZ)as precursor,carbon fiber reinforced SiBCN matrix composites(C_f/SiBCN)were fabricated by a modified polymer infiltration and pyrolysis(PIP)process.With dicumyl peroxide added as cross-linking agent,the PMVBSZ could be solidified at a low temperature of 120℃,leading to a high ceramic yield of~70%.The cross-linking mechanism and ceramization processes of the precursor were investigated in detail.Moreover,a modified infiltration technology was developed,which improved the efficiency and protected the precursor against moist air during PIP.Consequently,the obtained C_f/SiBCN composites had an oxygen content of around 1.22 wt%.Benefiting from the high ceramic yield and high efficiency of the modified PIP,C_f/SiBCN composites with an open porosity of~10%and uniform microstructure were obtained after only 7 cycles of PIP.The flexural strength and fracture toughness of the derived C_f/SiBCN composites were 371 MPa and 12.9 MPa·m^(1/2),respectively.This work provides a potential route for the fabrication of high performance C_f/SiBCN composites. | Qi DING Dewei NI Zhen WANG Hao ZHONG Hongda WANG Haijun ZHOU Yanmei KAN Shaoming DONG | 2018 | Journal of Advanced Ceramics2018，7，3： | 9 |
| 3 | Advances in ultra-high temperature ceramics,composites,and coatings显示文摘Ultra-high temperature ceramics(UHTCs)are generally referred to the carbides,nitrides,and borides of the transition metals,with the Group IVB compounds(Zr&Hf)and TaC as the main focus.The UHTCs are endowed with ultra-high melting points,excellent mechanical properties,and ablation resistance at elevated temperatures.These unique combinations of properties make them promising materials for extremely environmental structural applications in rocket and hypersonic vehicles,particularly nozzles,leading edges,and engine components,etc.In addition to bulk UHTCs,UHTC coatings and fiber reinforced UHTC composites are extensively developed and applied to avoid the intrinsic brittleness and poor thermal shock resistance of bulk ceramics.Recently,high-entropy UHTCs are developed rapidly and attract a lot of attention as an emerging direction for ultra-high temperature materials.This review presents the state of the art of processing approaches,microstructure design and properties of UHTCs from bulk materials to composites and coatings,as well as the future directions. | Dewei NI Yuan CHENG Jiaping ZHANG Ji-Xuan LIU Ji ZOU Bowen CHEN Haoyang WU Hejun LI Shaoming DONG Jiecai HAN Xinghong ZHANG Qiangang FU Guo-Jun ZHANG | 2022 | Journal of Advanced Ceramics2022，11，1： | 9 |
| 4 | Advances in crop phenotyping and multi-environment trials显示文摘Efficient evaluation of crop phenotypes is a prerequisite for breeding, cultivar adoption, genomics and phenomics study. Plant genotyping is developing rapidly through the use of high-throughput sequencing techniques,while plant phenotyping has lagged far behind and it has become the rate-limiting factor in genetics, large-scale breeding and development of new cultivars. In this paper,we consider crop phenotyping technology under three categories. The first is high-throughput phenotyping techniques in controlled environments such as greenhouses or specifically designed platforms. The second is a phenotypic strengthening test in semi-controlled environments, especially for traits that are difficult to be tested in multi-environment trials(MET), such as lodging, drought and disease resistance. The third is MET in uncontrolled environments, in which crop plants are managed according to farmer's cultural practices. Research and application of these phenotyping techniques are reviewed and methods for MET improvement proposed. | Zhe LIU Fan ZHANG Qin MA Dong AN Lin LI Xiaodong ZHANG Dehai ZHU Shaoming LI | 2015 | Frontiers of Agricultural Science and Engineering2015，2，1： | 7 |
| 5 | Oxyvanite V3O5:A new intercalation-type anode for lithium-ion battery显示文摘In the present study,V3O5 microcrystals that synthesized via vacuum calcination are employed as anodes for lithium-ion batteries(LIBs)for the first time.Despite the widely observed sluggish reaction kinetics and poor cycling stability in most microsized transition metal oxides,the V3O5 microcrystals exhibit excellent rate capability(specific capacities of 144 and 125 mAh g^−1 are achieved at extremely high current densities of 20 and 50 A g^−1,respectively)and long-term cycling performance(specific capacity of 117 mAh g^−1 is sustained over 2000 cycles at 50 A g^−1).It is ascribed to the three-dimensional open-framework structure of the V3O5 microcrystals as a major factor in dictating the fast reaction kinetics(lithium diffusion coefficient:~10−9 cm^2 s^−1).In addition,significant insight into the reaction mechanism of the V3O5 microcrystals in concomitant its phase evolution are obtained from ex-situ XRD study,revealing that the V3O5 microcrystals undergo intercalation reaction with insignificant structural change in response to lithiation/delithiation. | Dong Chen Huiteng Tan Xianhong Rui Qi Zhang Yuezhan Feng Hongbo Geng Chengchao Li Shaoming Huang Yan Yu | 2019 | InfoMat2019，1，2： | 6 |
| 6 | Fabrication and microstructure of ZrB_2–ZrC–SiC coatings on C/C composites by reactive melt infiltration using ZrSi_2 alloy显示文摘ZrB_2–ZrC–SiC ternary coatings on C/C composites are investigated by reactive melt infiltration of ZrSi_2 alloy into pre-coatings. Two different pre-coating structures, including porous B_4C–C and dense C/B, are designed by slurry dip and chemical vapor deposition(CVD) process respectively. The coating prepared by reactive melt infiltration(RMI) into B_4C–C presents a flat and smooth surface with a three-layer cross-sectional structure, namely interior SiC transition layer, gradient ZrB_2–ZrC–SiC layer, and ZrB_2–ZrC exterior layer. In comparison, the coating prepared by RMI into C/B shows a more granular surface with a different three-layer cross-sectional structure, interior unreacted B–C pre-coating layer, middle SiC layer, and exterior ZrB_2–ZrC–ZrSi_2 layer. The forming mechanisms of the specific microstructures in two coatings are also investigated and discussed in detail. | Chaoqiang XUE Haijun ZHOU Jianbao HU Hongda WANG Jiayue XU Shaoming DONG | 2018 | Journal of Advanced Ceramics2018，7，1： | 6 |
| 7 | Reaction mechanism and microstructure development of ZrSi_(2) melt-infiltrated C_(f)/SiC-ZrC-ZrB_(2) composites:The influence of preform pore structures显示文摘Reactive melt infiltration(RMI)is an effective method for fabrication of highly dense carbon fiber reinforced ultra-high temperature ceramic matrix composites(Cf/UHTCs).In this work,C_(f)/SiC-ZrC-ZrB_(2)composites were fabricated by infiltrating ZrSi_(2)melt into porous C_(f)/B_(4)C-C preforms,where the physical and chemical reactions involved during the RMI process were identified and analyzed.Inhomogeneous infiltration between the inter-and intra-bundle pores was revealed,and was found to be strongly related to the pore structures of the C_(f)/B_(4)C-C preform.It is indicated that the inhomogeneous infiltration can be mitigated remarkably with increasing porosity and pore size of the preform.The effect of pore size on the RMI process was also investigated by a quantitative model,which agrees very well with the experiment results.It further indicates that the inhomogeneous infiltration can also be relieved at elevated RMI temperature.However,excessive infiltration at elevated temperature or more porous preform may cause serious erosion on interphase and fibers,leading to mechanical properties deterioration of the final composites. | Xiaowu Chen Dewei Ni Yanmei Kan Youlin Jiang Haijun Zhou Zhen Wang Shaoming Dong | 2018 | Journal of Materiomics2018，4，3： | 5 |
| 8 | Microstructure and mechanical properties of 3D Cf/SiBCN composites fabricated by polymer infiltration and pyrolysis显示文摘In this work,three-dimensional(3D)Cf/SiBCN composites were fabricated by polymer infiltration and pyrolysis(PIP)with poly(methylvinyl)borosilazane as SiBCN precursor.The 3D microstructure evolution process of the composites was investigated by an advanced X-ray computed tomography(XCT).The effect of dicumyl peroxide(DCP)initiator addition on the crosslinking process,microstructure evolution,and mechanical properties of the composites were uncovered.With the addition of a DCP initiator,the liquid precursor can cross-linking to solid-state at 120℃.Moreover,DCP addition decreases the release of small molecule gas during pyrolysis,leading to an improved ceramic yield 4.67 times higher than that without DCP addition.After 7 PIP cycles,density and open porosity of the final Cf/SiBCN composite with DCP addition are 1.73 g.cm^(-3)and〜10%,respectively,which are 143.0%higher and 30.3%lower compared with the composites without DCP addition.As a result,the flexural strength and elastic modulus of Cf/SiBCN composites with DCP addition(371 MPa and 31 GPa)are 1.74 and 1.60 times higher than that without DCP addition(213 MPa and 19.4 GPa),respectively. | Bowen CHEN Qi DING Dewei NI Hongda WANG Yusheng DING Xiangyu ZHANG Shaoming DONG | 2021 | Journal of Advanced Ceramics2021，10，1： | 4 |

| 10 | Identification of maize seed varieties based on near infrared reflectance spectroscopy and chemometrics显示文摘False seeds can often be seen in the maize seed market,leading to a serious decline in maize yield.Those existing variety identification methods are expensive,time consuming,and destructive to seeds.The aim of this study is to develop a cheap,fast and non-destructive method which can robustly identify large amounts of maize seed varieties based on near-infrared reflectance spectroscopy(NIRS)and chemometrics.Because it is difficult to establish models for every variety in the market,this study mainly investigated the performance of models based on a large number of samples(more than 40 major varieties in the market).The reflectance spectra of maize seeds were collected by two modes(bulk kernels mode and single kernel mode).Both collection modes can be applied to identification,but only the single kernel mode can be applied to purity sorting.The spectra were pretreated with smoothing,the first derivative and vector normalization;and then principal component analysis(PCA),linear discriminant analysis(LDA)and biomimetic pattern recognition(BPR)were applied to establish identification models.The environmental factors such as producing areas and years have a significant influence on the performance of the models.Therefore,the method to improve the robustness of the models was investigated in this study.New indexes(correct acceptance degree(CAD),correct rejection degree(CRD)and correct degree(CD))were defined to analyze the performance of the models more accurately.Finally,the models obtained a mean correct discrimination rate of over 90%,and exhibited robust properties for samples harvested from different areas and years.The results showed that NIR technology combined with chemometrics methods such as PCA,LDA,and BPR could be a suitable and alternative technique to identify the authenticity of maize seed varieties. | Yongjin Cui Lanjun Xu Dong An Zhe Liu Jiancheng Gu Shaoming Li Xiaodong Zhang Dehai Zhu | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 3 |
| 11 | Residual stress variation in SiC_(f)/SiC composite during heat treatment and its effects on mechanical behavior显示文摘Residual stress originated from thermal expansion mismatch determines the mechanical properties of ceramic matrix composites(CMCs).Here,continuous SiC fiber reinforced SiC matrix(SiC_(f)/SiC)composites were fabricated by nano-infiltration and transient eutectic-phase(NITE)method,and the residual stress of the composites was investigated using high-temperature Raman spectrometer.With temperature increasing from room temperature to 1400℃,the residual stresses of the matrix and the fiber decrease from 1.29 to 0.62 GPa and from 0.84 to 0.55 GPa in compression respectively,while that of the interphase decreases from 0.16 to 0.10 GPa in tension.The variation of residual stress shows little effect on the tensile strength of the composites,while causes a slight decrease in the tensile strain.The suppression of fiber/matrix debonding and fiber pulling-out caused by the residual stress reduction in the interphase is responsible for the decreasing tensile strain.This work can open up new alternatives for residual stress analysis in CMCs. | Xiaowu CHEN Guofeng CHENG Junmin ZHANG Feiyu GUO Haijun ZHOU Chunjin LIAO Hongda WANG Xiangyu ZHANG Shaoming DONG | 2020 | Journal of Advanced Ceramics2020，9，5： | 3 |
| 12 | A High-Capacity Ammonium Vanadate Cathode for Zinc-Ion Battery显示文摘Given the advantages of being abundant in resources,environmental benign and highly safe,rechargeable zinc-ion batteries(ZIBs)enter the global spotlight for their potential utilization in large-scale energy storage.Despite their preliminary success,zinc-ion storage that is able to deliver capacity>400 mAh g^-1 remains a great challenge.Here,we demonstrate the viability of NH4V4O10(NVO)as high-capacity cathode that breaks through the bottleneck of ZIBs in limited capacity.The first-principles calculations reveal that layered NVO is a good host to provide fast Zn^2+ions diffusion channel along its[010]direction in the interlayer space.On the other hand,to further enhance Zn^2+ion intercalation kinetics and long-term cycling stability,a three-dimensional(3D)flower-like architecture that is self-assembled by NVO nanobelts(3D-NVO)is rationally designed and fabricated through a microwave-assisted hydrothermal method.As a result,such 3D-NVO cathode possesses high capacity(485 mAh g^-1)and superior long-term cycling performance(3000 times)at 10 A g^-1(~50 s to full discharge/charge).Additionally,based on the excellent 3D-NVO cathode,a quasi-solid-state ZIB with capacity of 378 mAh g^-1is developed. | Qifei Li Xianhong Rui Dong Chen Yuezhan Feng Ni Xiao Liyong Gan Qi Zhang Yan Yu Shaoming Huang | 2020 | Nano-Micro Letters2020，12，5： | 2 |

| 15 | Fabrication and microstructure evolution of C_(sf)/ZrB_(2)-SiC composites via direct ink writing and reactive melt infiltration显示文摘Fiber damage and uniform interphase preparation are the main challenges in conventional short fiber reinforced ceramic matrix composites.In this work,we develop a novel processing route in fabrication of short carbon fiber reinforced ZrB_(2)-SiC composites(C_(sf)/ZrB_(2)-SiC)overcoming the above two issues.At first,C_(sf) preforms with oriented designation and uniform PyC/SiC interphase are fabricated via direct ink writing(DIW)of short carbon fiber paste followed by chemical vapor infiltration.After that,ZrB_(2) and SiC are introduced into the preforms by slurry impregnation and reactive melt infiltration,respectively.Microstructure evolution and optimization of the composites during fabrication are investigated in detail.The as-fabricated C_(sf)/ZrB_(2)-SiC composites have a bulk density of 2.47 g/cm^(3),with uniform weak interphase and without serious fiber damage.Consequently,non-brittle fracture occurs in the C_(sf)/ZrB_(2)-SiC composites with widespread toughening mechanisms such as crack deflection and bridging,interphase debonding,and fiber pull-out.This work provides a new opportunity to the material design and selection of short fiber reinforced composites. | Jun LU Dewei NI Chunjing LIAO Haijun ZHOU Youlin JIANG Bowen CHEN Xuegang ZOU Feiyan CAI Yusheng DING Shaoming DONG | 2021 | Journal of Advanced Ceramics2021，10，6： | 1 |
