| 1 | Defect detection in atomic-resolution images via unsupervised learning with translational invariance显示文摘Crystallographic defects can now be routinely imaged at atomic resolution with aberration-corrected scanning transmission electron microscopy(STEM)at high speed,with the potential for vast volumes of data to be acquired in relatively short times or through autonomous experiments that can continue over very long periods.Automatic detection and classification of defects in the STEM images are needed in order to handle the data in an efficient way.However,like many other tasks related to object detection and identification in artificial intelligence,it is challenging to detect and identify defects from STEM images.Furthermore,it is difficult to deal with crystal structures that have many atoms and low symmetries.Previous methods used for defect detection and classification were based on supervised learning,which requires human-labeled data.In this work,we develop an approach for defect detection with unsupervised machine learning based on a one-class support vector machine(OCSVM).We introduce two schemes of image segmentation and data preprocessing,both of which involve taking the Patterson function of each segment as inputs.We demonstrate that this method can be applied to various defects,such as point and line defects in 2D materials and twin boundaries in 3D nanocrystals. | Yueming Guo Sergei V.Kalinin Hui Cai Kai Xiao Sergiy Krylyuk Albert V.Davydov Qianying Guo Andrew R.Lupini | 2021 | npj Computational Materials2021，，1： | 2 |
| 2 | Effects of dry fog humidification on pericarp browning and quality of litchi fruit stored at low temperature显示文摘Pericarp browning is the major cause of deterioration of harvested litchi fruit.Water loss plays a role in pericarp browning of litchi fruit.This study investigated the effects of humidification with dry fog on pericarp browning and quality of litchi fruit stored at low temperature.Litchi fruit were stored in a non-humidified cold chamber(control)or in a humidified cold room using Tabor atomizer system that generated 95%relative humidity(RH)without depositing water on the fruit surface at 4℃.Control fruit stored in cold room without added humidity underwent rapid weight loss,accompanied by severe pericarp browning after 25 d of storage.However,slight weight loss and no obvious pericarp browning were found in humidified-fruit.Moreover,humidification maintained well the integrity of cell membrane and inhibited polyphenol oxidase activity during early storage.In addition,respiration rate was obviously inhibited in humidified-fruit compared with control fruit.This study might provide a convenient approach to reduce pericarp browning of harvested litchi fruit by humidifying the fruit using the Tabor atomizer at low temperature instead of packaging with film. | Lu Xiao Taotao Li Guoxiang Jiang Afiya John Dandan Zhang Wenyuan Jin Xuewu Duan Yueming Jiang | 2019 | International Journal of Agricultural and Biological Engineering2019，12，4： | 2 |

| 5 | Reconstruction and petroleum geological significance of lithofacies paleogeography and paleokarst geomorphology of the Middle Permian Maokou Formation in northwestern Sichuan Basin,SW China显示文摘Based on analysis of outcrop,drilling,logging and seismic data,and geotectonic background,the lithofacies paleogeography and paleokarst geomorphology of the Middle Permian Maokou Formation in the northwestern Sichuan Basin were reconstructed,and the petroleum geological significance of the lithofacies paleogeography and paleokarst geomorphology were discussed.The Maokou Formation is divided into 3 long-term cycles,namely LSCl,LSC2 and LSC3,which correspond to the Member 1,Member 2 and Member 3 of the Maokou Formation,respectively.Controlled by the extensional structure caused by opening of the Mianlue Ocean in the north margin of the upper Yangtze blocks and basement faults produced by mantle plume uplifting,the area had tectonic differentiation in NWW and NE,and sedimentary basement took on episodic settlement from north to south,as a result,the sedimentary systems of Member 1 to Member 3 gradually evolved from carbonate platform to platform-slope-continental shelf.According to the residual thickness,paleokarst geomorphologic units such as karst highland,karst slope and karst depression at different stages were reconstructed.The karst geomorphological units were developed successively on the basis of sedimentary geomorphology.Sedimentary facies and paleokarst geomorphology are of great significance for oil and gas accumulation.The Maokou Formation in northwestern Sichuan has two kinds of most favorable reservoir zone combinations:high energy grain shoal and karst monadnock,platform margin slope and karst slope.Based on this understanding,the planar distribution of the two kinds of reservoir zones were predicted by overlapping the favorable reservoir facies belt with paleokarst geomorphology.The study results provide a new idea and reference for the exploration deployment of the Middle Permian Maokou Formation in the Sichuan Basin. | ZHONG Yuan YANG Yueming WEN Long LUO Bing XIAO Di LI Minglong CHEN Cong ZHAO Like LU Feifan TAN Xiucheng | 2021 | Petroleum Exploration and Development2021，48，1： | 1 |
| 6 | Application of Isotope Tracer Technique in Source Apportionment of Heavy Metal Pollution in Soil显示文摘The formation of heavy metal pollution in soil is closely related to human production and life. In order to effectively control heavy metal pollution and repair damaged soil,the pollution source should be known and judged first. Based on the preliminary analysis of major sources of soil heavy metal pollution in soil,combined with relevant literatures on heavy metal pollution source of soil or sediment at home and abroad in recent years,application progress of isotope tracer technique,especially lead isotope tracer technique,in the study of heavy metal pollution sources in soils and sediments were reviewed. The key points of future isotope tracer technology in the field of heavy metal pollution source apportionment were prospected. | Lin Ying Ke Nafen Chen Longjie Xiao Yueming Huang Huabin | 2017 | Plant Diseases and Pests2017，8，5： | 1 |
| 7 | Alkali-metal hexamethyldisilazide initiated polymerization on alpha-amino acid N-substituted N-carboxyanhydrides for facile polypeptoid synthesis显示文摘Polypeptoids have been explored as mimics of polypeptides,owing to polypeptoids'superior stability upon proteolysis.Polypeptoids can be synthesized from one-pot ring-opening polymerization of amino acid N-substituted N-carboxyanhydrides(NNCAs).However,the speed of polymerization of NNCAs can be very slow,especially for NNCAs bearing a bulky N-substitution group.This hindered the exploration on polypeptoids with more diverse structures and functions.Therefore,it is in great need to develop advanced strategies that can accelerate the polymerization on inactive NNCAs.Hereby,we report that lithium/sodium/potassium hexamethyldisilazide(Li/Na/KHMDS)initiates a substantially faster polymerization on NNCAs than do commonly used amine initiators,especially for NNCAs with bulky N-substitution group.This fast NNCA polymerization will increase the structure diversity and application of polypeptoids as synthetic mimics of polypeptides. | Yueming Wu Min Zhou Kang Chen Sheng Chen Ximian Xiao Zhemin Ji Jingcheng Zou Runhui Liu | 2021 | Chinese Chemical Letters2021，32，5： | 1 |

| 10 | Application of Cadmium Isotope Tracer Technique显示文摘Cadmium( Cd) is a strong carcinogenic heavy metal element. Because of its physical,chemical and toxicological characteristics,Cd environmental geochemical research has been concerned,and Cd detection technology is becoming more and more perfect. Cd isotope is one of the hotspots of non-traditional isotope research in recent years. One-way fractionation takes place in its evolution process,which makes the region or process significantly different and contains the information of its evolution environment and process,and Cd isotope tracer technique has been successfully applied to the study of the genesis of lead-zinc deposits,lunar soil and meteorites,marine environment and heavy metal pollution,and has become an important means to the analysis of the sources of Cd pollution. The determination technology of Cd and Cd isotope and its application were reviewed,and the future research points of Cd isotope technology were prospected. | ying lin yueming xiao nafen ke longjie chen huabin huang | 2018 | Agricultural Biotechnology2018，7，2： | 1 |

| 14 | Distribution and Migration Patterns of Lead in Atmosphere-tea System by Isotopic Tracing Method显示文摘With low concentration of stable lead isotope as the tracer,using inductively coupled plasma mass spectrometry( ICP-MS),the lead absorption of tea plants as well as the distribution and migration pattern of lead in plants under different p H environments and spraying introduction of lead sources were studied through pot trial. The results showed that tea plants were very sensitive to atmospheric lead source pollution; atmospheric lead source pollution had a tendency of moving up to the top( bud); low p H conditions enhanced lead absorption of plants and promoted upward migration of lead in plants. The experimental method is closer to the actual situation that plants are exposed to low concentration pollution,and could distinguish experimentally introduced lead source from environmentally introduced lead source. | Huang Huabin Yang Miaofeng Lin Ying Ke Nafen Xiao Yueming Zhuang Zhixia Wang Xiaoru | 2017 | Plant Diseases and Pests2017，8，4： | 0 |
| 15 | Enhanced bone regenerative properties of calcium phosphate ceramic granules in rabbit posterolateral spinal fusion through a reduction of grain size显示文摘Osteoinductivity is a crucial factor to determine the success and efficiency of posterolateral spinal fusion(PLF)by employing calcium phosphate(Ca-P)bioceramics.In this study,three kinds of Ca-P ceramics with microscale to nanoscale gain size(BCP-control,BCP-micro and BCP-nano)were prepared and their physicochemical properties were characterized.BCP-nano had the spherical shape and nanoscale gain size,BCP-micro had the spherical shape and microscale gain size,and BCP-control(BAM®)had the irregular shape and microscale gain size.The obtained BCP-nano with specific nanotopography could well regulate in vitro protein adsorption and osteogenic differentiation of MC3T3 cells.In vivo rabbit PLF procedures further confirmed that nanotopography of BCP-nano might be responsible for the stronger bone regenerative ability comparing with BCP-micro and BCP-control.Collectedly,due to nanocrystal similarity with natural bone apatite,BCP-nano has excellent efficacy in guiding bone regeneration of PLF,and holds great potentials to become an alternative to standard bone grafts for future clinical applications. | Xiangfeng Li Quan Zhou Yonghao Wu Cong Feng Xi Yang Linnan Wang Yumei Xiao Kai Zhang Xiangdong Zhu Limin Liu Yueming Song Xingdong Zhang | 2022 | Bioactive Materials2022，7，5： | 0 |
| 16 | Influence of Different Equations of State on Simulation Results of Supercritical CO_(2) Centrifugal Compressor显示文摘Supercritical CO_(2)(SCO_(2))Brayton cycle has received more and more attention in the field of power generation due to its high cycle efficiency and compact structure.SCO_(2) compressor is the core component of the cycle,and the improvement of its performance is the key to improving the efficiency of the entire cycle.However,the operation of the SCO_(2) compressor near the critical point has brought many design and operation problems.Based on the Reynolds Averaged Navier-Stokes(RANS)model,the performance and flow field of SCO_(2) centrifugal compressors based on different CO_(2) working fluid models are numerically investigated in this paper.The stability and convergence of the compressor steady-state simulation are also discussed.The results show that the fluid based on the Span-Wanger(SW)equation can obtain a more ideal compressor performance curve and capture a more accurate flow field structure,while the CO_(2) ideal gas is not suitable for the calculation of SCO_(2) centrifugal compressors.But its flow field can be used as the initial flow field for numerical calculation of centrifugal compressor based on CO_(2) real gas. | Yueming YANG Bingkun MA Yongqing XIAO Jianhui QI | 2021 | Mechanical Engineering Science2021，3，2： | 0 |
| 17 | Controllable Polymerization of N-Substituted β-Alanine N-Thiocarboxyanhydrides for Convenient Synthesis of Functional Poly(β-peptoid)s显示文摘Poly(β-peptoid)is a class of polypeptide mimics that possesses excellent biocompatibility and resistance to proteolysis.However,the synthesis of poly(β-peptoid)s with functionalities is a long-standing challenge that greatly hinders the functional study and application of poly(β-peptoid)s.We report a controllable and easy synthesis of poly(β-peptoid)s bearing diverse functionalities via the ring-opening polymerization on N-substitutedβ-alanine N-thiocarboxyanhydrides(β-NNTAs).The polymerization can be carried out in openvesselsundermildconditions usingaminesas the initiators to provide poly(β-peptoid)s with targeted molecular weights,narrow dispersities,and diverse functionalities in the side chains and termini.Theβ-NNTAs polymerization is even compatible with initiators bearing unprotected hydroxyl groups.The amphiphilic/cationic poly(β-peptoid)s exhibit a broad spectrum and potent antibacterial activities against multidrug-resistant bacteria.In addition,the highly favored stability ofβ-NNTAmonomers for purification and storage highlights the advantages of thisβ-NNTA polymerization strategy for poly(β-peptoid)s synthesis,functional study,and application as a synthetic mimic of polypeptides. | Ximian Xiao Min Zhou Zihao Cong Longqiang Liu Jingcheng Zou Zhemin Ji Ruxin Cui Yueming Wu Haodong Zhang Sheng Chen Maoquan Li Runhui Liu | 2023 | CCS Chemistry2023，5，4： | 0 |
