| 1 | CPS Modeling of CNC Machine Tool Work Processes Using an Instruction-Domain Based Approach显示文摘Building cyber-physical system(CPS) models of machine tools is a key technology for intelligent manufacturing. The massive electronic data from a computer numerical control(CNC) system during the work processes of a CNC machine tool is the main source of the big data on which a CPS model is established. In this work-process model, a method based on instruction domain is applied to analyze the electronic big data, and a quantitative description of the numerical control(NC) processes is built according to the G code of the processes. Utilizing the instruction domain, a work-process CPS model is established on the basis of the accurate, real-time mapping of the manufacturing tasks, resources, and status of the CNC machine tool. Using such models, case studies are conducted on intelligent-machining applications, such as the optimization of NC processing parameters and the health assurance of CNC machine tools. | Jihong Chen Jianzhong Yang Huicheng Zhou Hua Xiang Zhihong Zhu Yesong Li Chen-Han Lee Guangda Xu | 2015 | Engineering2015，1，2： | 17 |

| 4 | Antimony doped Cs2SnCl6 with bright and stable emission显示文摘Lead halide perovskites,with high photoluminescence efficiency and narrow・band emission,are promising materials for display and lighting.However,the lead toxicity and environmental sensitivity hinder their potential applications.Herein,a new antimony・doped lead-free inorganic perovskites variant Cs2SnCl6:xSb is designed and synthesized.The perovskite variant Cs2SnCl6:xSb exhibits a broadband orange-red emission,with a photoluminescence quantum yield(PLQY)of 37%.The photoluminescence of Cs2SnCl6:xSb is caused by the ionoluminescence of Sb3+within Cs2SnCl6 matrix,which is verified by temperature dependent photoluminescence(PL)and PL decay measurements.In addition,the all inorganic structure renders Cs2SnCl6:xSb with excellent thermal and water stability.Finally,a white light-emitting diode(white-LED)is fabricated by assembling Cs2SnCl6:0.59%Sb,Cs2SnCl6:2.75%Bi and Ba2Sr2SiO4:Eu2+onto the commercial UV LED chips,and the color rendering index(CRI)reaches 81. | Jinghui LI Zhifang TAN Manchen HU Chao CHEN Jiajun LUO Shunran LI Liang GAO Zewen XIAO Guangda NIU Jiang TANG | 2019 | Frontiers of Optoelectronics2019，12，4： | 2 |
| 5 | Organic–inorganic hybrid perovskite scintillators for mixed field radiation detection显示文摘Sensitive and fast detection of neutrons and gamma rays is vital for homeland security,high-energy physics,and proton therapy.Fast-neutron detectors rely on light organic scintillators,andγ-ray detectors use heavy inorganic scintillators and semiconductors.Efficient mixed-field detection using a single material is highly challenging due to their contradictory requirements.Here we report hybrid perovskites(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)that combine light organic cations and heavy inorganic skeletons at a molecular level to achieve unprecedented performance for mixed-field radiation detection.High neutron absorption due to a high density of hydrogen,strong radiative recombination within the highly confined[PbX_(6)]^(4-)layer,and sub-nanometer distance between absorption sites and radiative centers,enable a light yield of 41000 photons/MeV,detection pulse width of 2.97 ns and extraordinary linearity response toward both fast neutrons andγ-rays,outperforming commonly used fast-neutron scintillators.Neutron energy spectrum,time-of-flight based fast-neutron/γ-ray discrimination and neutron yield monitoring were all successfully achieved using(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)detectors.We further demonstrate the monitoring of reaction kinetics and total power of a nuclear fusion reaction.We envision that molecular hybridized scintillators open a new avenue for mixed-field radiation detection and imaging. | Mengling Xia Guangda Niu Linyue Liu Runlong Gao Tong Jin Pengying Wan Weicheng Pan Xianpeng Zhang Zuoxiang Xie Sam Teale Zenghua Cai Jiajun Luo Shan Zhao Haodi Wu Shiyou Chen Zhiping Zheng Qingguo Xie Xiaoping Ouyang Edward HSargent Jiang Tang | 2022 | InfoMat2022，4，9： | 2 |
| 6 | A comprehensive overview of cotton genomics,biotechnology and molecular biological studies显示文摘Cotton is an irreplaceable economic crop currently domesticated in the human world for its extremely elongated fiber cells specialized in seed epidermis,which makes it of high research and application value.To date,numerous research on cotton has navigated various aspects,from multi-genome assembly,genome editing,mechanism of fiber development,metabolite biosynthesis,and analysis to genetic breeding.Genomic and 3D genomic studies reveal the origin of cotton species and the spatiotemporal asymmetric chromatin structure in fibers.Mature multiple genome editing systems,such as CRISPR/Cas9,Cas12(Cpf1)and cytidine base editing(CBE),have been widely used in the study of candidate genes affecting fiber development.Based on this,the cotton fiber cell development network has been preliminarily drawn.Among them,the MYB-b HLH-WDR(MBW)transcription factor complex and IAA and BR signaling pathway regulate the initiation;various plant hormones,including ethylene,mediated regulatory network and membrane protein overlap fine-regulate elongation.Multistage transcription factors targeting Ces A 4,7,and 8 specifically dominate the whole process of secondary cell wall thickening.And fluorescently labeled cytoskeletal proteins can observe real-time dynamic changes in fiber development.Furthermore,research on the synthesis of cotton secondary metabolite gossypol,resistance to diseases and insect pests,plant architecture regulation,and seed oil utilization are all conducive to finding more high-quality breeding-related genes and subsequently facilitating the cultivation of better cotton varieties.This review summarizes the paramount research achievements in cotton molecular biology over the last few decades from the above aspects,thereby enabling us to conduct a status review on the current studies of cotton and provide strong theoretical support for the future direction. | Xingpeng Wen Zhiwen Chen Zuoren Yang Maojun Wang Shuangxia Jin Guangda Wang Li Zhang Lingjian Wang Jianying Li Sumbul Saeed Shoupu He Zhi Wang Kun Wang Zhaosheng Kong Fuguang Li Xianlong Zhang Xiaoya Chen Yuxian Zhu | 2023 | Science China(Life Sciences)2023，66，10： | 2 |
| 7 | Inorganic Hierarchical Nanostructures Induced by Concentration Difference and Gradient显示文摘A very simple strategy for preparing hierarchical inorganic nanostructures under ambient aqueous conditions is presented.The hierarchical inorganic nanomaterials were obtained by simply adding a highly concentrated solution of one reactant to a solution of another reactant with low concentration.No surface-capping molecules or structure-directing templates were needed.The preparation of hierarchical single crystalline PbMoO4 was used as an example in order to study the effects of varying the reaction conditions and the mechanism of the process.It was found that the large concentration difference(typically in excess of 200-fold)and the concentration gradient of the reactants both play key roles in controlling the diffusion process and the morphology of the resulting nanostructures.This kinetically controlled strategy is facile and is easily adapted to prepare a variety of inorganic materials. | Haibin Chu Xuemei Li Guangda Chen Zhong Jin Yan Zhang Yan Li | 2008 | Nano Research2008，1，3： | 1 |

| 9 | High-speed reconstruction for ultra-low resolution faces显示文摘In this paper,a learning-based high-speed reconstruction system for ultra-low resolution faces is implemented using a software/hardware co-design paradigm.The hardware component working at 60 MHz contains a field programmable gate array,which is reconfigured to contain parallel processing units,and multiple memories to create parallel data.The hardware component effectively handles generating and sorting computationally intensive similarity metrics.This solves the processing speed problem in learning-based super-resolution reconstruction for ultra-low resolution faces.The system can reconstruct faces using 8 × 6,16 × 12,and 32 × 24 sized images,with 4 × 4,8 × 8,or 16 × 16 times magnification.The experimental results verify the effectiveness of our system in terms of both visual effect and low root mean square errors.The processing speed can be improved up to a maximum of 7900 times faster than a pure software implementation using C. | WANG Li CHEN JianSheng HE JinPing SU GuangDa | 2012 | Science China(Information Sciences)2012，55，9： | 1 |

| 11 | Sb_(2)Se_(3) film with grain size over 10μm toward X-ray detection显示文摘Direct X-ray detectors are considered as competitive next-generation X-ray detectors because of their high spatial resolution,high sensitivity,and simple device configuration.However,their potential is largely limited by the imperfections of traditional materials,such as the low crystallization temperature of α-Se and the low atomic numbers of α-Si and α-Se.Here,we report the Sb_(2)Se_(3) X-ray thin-film detector with a p-n junction structure,which exhibited a sensitivity of 106.3 μC/(Gyair·cm^(2))and response time of<2.5 ms.This decent performance and the various advantages of Sb_(2)Se_(3),such as the average atomic number of 40.8 and μτ product(μ is the mobility,and τ is the carrier lifetime)of 1.29×1O^(-5) cm^(2)/V,indicate its potential for application in X-ray detection. | Chong WANG Xinyuan DU Siyu WANG Hui DENG Chao CHEN Guangda NIU Jincong PANG Kanghua LI Shuaicheng LU Xuetian LIN Haisheng SONG Jiang TANG | 2021 | Frontiers of Optoelectronics2021，14，3： | 0 |
| 12 | Template directed perovskite X-ray detectors towards low ionic migration and low interpixel cross talking显示文摘The metal halide perovskites exhibit excellent performance as the direct X-ray detectors owing to their strong absorption capability,long carrier lifetime and diffusion length,radiation ruggedness,etc.For imaging applications,the ionic migration of perovskites and charge sharing effect between the adjacent pixels have a significantly negative impact on the spatial resolution.Herein,for the first time,the porous anodic aluminum oxides(AAO)have been used as a template to grow the CsPbBr2I thick film for the direct X-ray detection.Benefiting from the oxygen passivation effect,the activation energy for ionic migration has been observed to increase to 0.701 eV,whereas the dark current drift(1.01×10^(-5)nA cm^(-1)s^(-1)V^(-1))is one to two orders of magnitude lower than the other lead halide perovskite single crystals and films.Moreover,the AAO insulating wall effectively blocks the charge diffusion effect across a pixel pitch of 10^m.Overall,the findings reported in this study open a new route for reducing the ionic migration and pixel crosstalk,thus,bringing the perovskite X-ray detectors close to the practical applications. | Menghua Zhu Xinyuan Du Guangda Niu Weiwei Liu Weicheng Pan Jincong Pang Wenyu Wang Chao Chen Yadong Xu Jiang Tang | 2022 | Fundamental Research2022，2，1： | 0 |

| 14 | Hierarchical Sponge-Hydrogel Hybrid Structures with Robust Interfaces显示文摘Soft materials including elastomers and hydrogels are playing critical roles in a variety of fields,including bioelectrodes,batteries,supercapacitors,biomedical scaffolds,and solar vapor absorbents.Integrating hydrophobic sponges(i.e.,mechanical robustness,elasticity and macroscopic porous structure)and hydrophilic hydrogels(i.e.,autonomous water absorption and transportation,biocompatibility)within one unit could readily combine the complementary characters from each component,making a number of future research directions and applications possible.We propose a simple yet effective strategy to construct sponge-hydrogel hybrid structures with robust hydrophobic-hydrophilic interface.The sponge scaffold imparts the sponges-hydrogel hybrids with desirable mechanical robustness,elasticity and macroscopic pores.On the other hand,the incorporated hydrogel component endows the hybrids with high water content(98 wt%hydrogel and 2 wt%sponge),superior compatibility,and nanoscale pores allowing for storage and transportation of various chemical and biological molecules.We further demonstrate that the introduction of hydrophilic hydrogel components could effectively improve the liquid absorption capability,blood coagulation rate,hemostatic capacity and hemocompatibility,thus promising as hemostatic agents. | Pei Zhang Guangda Chen Xingmei Chen Junfei Xing Yue Tao Ji Liu | 2023 | Chinese Journal of Chemistry2023，41，20： | 0 |
