| 1 | Darwin:a neuromorphic hardware co-processor based on Spiking Neural Networks显示文摘Broadly speaking, the goal of neuromorphic engineering is to build computer systems that mimic the brain. Spiking Neural Network(SNN) is a type of biologically-inspired neural networks that perform information processing based on discrete-time spikes, different from traditional Artificial Neural Network(ANN).Hardware implementation of SNNs is necessary for achieving high-performance and low-power. We present the Darwin Neural Processing Unit(NPU), a neuromorphic hardware co-processor based on SNN implemented with digitallogic, supporting a maximum of 2048 neurons, 20482= 4194304 synapses, and 15 possible synaptic delays.The Darwin NPU was fabricated by standard 180 nm CMOS technology with an area size of 5 × 5 mm2and70 MHz clock frequency at the worst case. It consumes 0.84 m W/MHz with 1.8 V power supply for typical applications. Two prototype applications are used to demonstrate the performance and efficiency of the hardware implementation. | Juncheng SHEN De MA Zonghua GU Ming ZHANG Xiaolei ZHU Xiaoqiang XU Qi XU Yangjing SHEN Gang PAN | 2016 | Science China(Information Sciences)2016，59，2： | 18 |

| 5 | In-plane heterostructured Ag_(2)S-In_(2)S_(3) atomic layers enabling boosted CO_(2) photoreduction into CH_(4)显示文摘Sluggish separation and migration kinetics of the photogenerated carriers account for the low-efficiency of CO_(2) photoreduction into CH_(4). Design and construction two-dimensional (2D) in-plane heterostructures demonstrate to be an appealing approach to address above obstacles. Herein, we fabricate 2D in-plane heterostructured Ag_(2)S-In_(2)S_(3) atomic layers via an ion-exchange strategy. Photoluminescence spectra, time-resolved photoluminescence spectra, and photoelectrochemical measurements firmly affirm the optimized carrier dynamics of the In_(2)S_(3) atomic layers after the introduction of in-plane heterostructure. In-situ Fourier transform infrared spectroscopy spectra and density functional theory (DFT) calculations disclose the in-plane heterostructure contributes to CO_(2) activation and modulates the adsorption strength of CO* intermediates to facilitate the formation of CHO* intermediates, which are further protonated to CH4. In consequence, the in-plane heterostructure achieves the CH_(4) evolution rate of 20 µmol·g^(−1)·h^(−1), about 16.7 times higher than that of the In2S3 atomic layers. In short, this work proves construction of in-plane heterostructures as a promising method for obtaining high-efficiency CO_(2)-to-CH_(4) photoconversion properties. | Weiwei Shao Shumin Wang Juncheng Zhu Xiaodong Li Xingchen Jiao Yang Pan Yongfu Sun Yi Xie | 2021 | Nano Research2021，14，12： | 1 |

| 9 | Hydrothermal Synthesis of Zn2SnO4/Few-Layer Boron Nitride Nanosheets Hybrids as a Visible-Light-Driven Photocatalyst显示文摘Zn2SnO4/few-layer boron nitride nanosheets (FBNNS) hybrids were synthesized via a one-step hydrothermal method. The structures, morphology, optical properties, electron transformation and separation of the as-prepared products were characterized by X-ray diffraction, transmission electrical microscopy, UV-vis diffuse reflectance spectroscopy and electrochemical impedance spectroscopy, respectively. Rhodamine B was used to evaluate the photocatalytic activities of the as-prepared samples under visible light illumination. The photocatalytic mechanism was also explored. Experimental results showed that the degradation efficiency of rhodamine B was firstly increased and then decreased with increasing the usage amount of FBNNS. When it was 9 wt% based on the weight of Zn2SnO4, the degradation efficiency of the as-prepared Zn2SnO4/FBNNS-9 wt% composites reached to the maximum of 97.5 % in 180 min, which was higher than 39.2 % of pure Zn2SnO4. Moreover, the holes played mainly active roles in photocatalytic reaction process. In addition, the as-prepared hybrids could enhance the separation efficiency of photoexcited carriers compared to pure Zn2SnO4. | 王一瑾 吴湘锋 ZHAO Zehua LI Hui ZHANG Chenxu SU Junzhang ZHANG Jiarui CAO Zuolin WANG Yiwei WANG Kaiyuan PAN Juncheng | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，3： | 1 |

| 13 | A novel long-term intravenous combined with local treatment with human amnion-derived mesenchymal stem cells for a multidisciplinary rescued uremic calciphylaxis patient and the underlying mechanism显示文摘Calciphylaxis is a rare disease characterized histologically by microvessel calcification and microthrombosis,with high mortality and no proven therapy.Here,we reported a severe uremic calciphylaxis patient with progressive skin ischemia,large areas of painful malodorous ulcers,and mummified legs.Because of the worsening symptoms and signs refractory to conventional therapies,treatment with human amnion-derived mesenchymal stem cells(hAMSCs)was approved.Preclinical release inspections of hAMSCs,efficacy,and safety assessment,including cytokine secretory ability,immunocompetence,tumorigenicity,and genetics analysis in vitro,were introduced.We further performed acute and long-term hAMSC toxicity evaluations in C57BL/6 mice and rats,abnormal immune response tests in C57BL/6 mice,and tumorigenicity tests in neonatal Balbc-nu nude mice.After the preclinical research,the patient was treated with hAMSCs by intravenous and local intramuscular injection and external supernatant application to the ulcers.When followed up to 15 months,the blood-based markers of bone and mineral metabolism improved,with skin soft tissue regeneration and a more favorable profile of peripheral blood mononuclear cells.Skin biopsy after 1-month treatment showed vascular regeneration with mature noncalcified vessels within the dermis,and 20 months later,the re-epithelialization restored the integrity of the damaged site.No infusion or local treatment-related adverse events occurred.Thus,this novel long-term intravenous combined with local treatment with hAMSCs warrants further investigation as a potential regenerative treatment for uremic calciphylaxis due to effects of inhibiting vascular calcification,stimulating angiogenesis and myogenesis,anti-inflammatory and immune modulation,multidifferentiation,re-epithelialization,and restoration of integrity. | Lianju Qin Jing Zhang Yujie Xiao Kang Liu Yugui Cui Fangyan Xu Wenkai Ren Yanggang Yuan Chunyan Jiang Song Ning Xiaoxue Ye Ming Zeng Hanyang Qian Anning Bian Fan Li Guang Yang Shaowen Tang Zhihong Zhang Juncheng Dai Jing Guo Qiang Wang Bin Sun Yifei Ge Chun Ouyang Xueqiang Xu Jing Wang Yaoyu Huang Hongqing Cui Jing Zhou Meilian Wang Zhonglan Su Yan Lu Di Wu Jingping Shi Wei Liu Li Dong Yinbing Pan Baiqiao Zhao Ying Cui Xueyan Gao Zhanhui Gao Xiang Ma Aiqin Chen Jie Wang Meng Cao Qian Cui Li Chen Feng Chen Youjia Yu Qiang Ji Zhiwei Zhang Mufeng Gu Xiaojun Zhuang Xiaolin Lv Hui Wang Yanyan Pan Ling Wang Xianrong Xu Jing Zhao Xiuqin Wang Cuiping Liu Ningxia Liang Changying Xing Jiayin Liu Ningning Wang | 2022 | Journal of Molecular Cell Biology2022，14，2： | 1 |
| 14 | High-rate CH_(4)-to-C_(2)H_(6) photoconversion enabled by Au/ZnO porous nanosheets under oxygen-free system显示文摘Photocatalytic CH_(4) coupling into high-valued C_(2)H_(6) is highly attractive,whereas the photosynthetic rate,especially under oxygen-free system,is still unsatisfying.Here,we designed the negatively charged metal supported on metal oxide nanosheets to activate the inert C-H bond in CH_(4)and hence accelerate CH_(4) coupling performance.As an example,the synthetic Au/ZnO porous nanosheets exhibit the C_(2)H_(6) photosynthetic rate of 1,121.6μmol g^(-1)_(cat)h^(-1)and the CH_(4) conversion rate of 2,374.6μmol g^(-1)_(cat)h^(-1) under oxygen-free system,2 orders of magnitude higher than those of previously reported photocatalysts.By virtue of several in situ spectroscopic techniques,it is established that the generated Au^(δ-)and O^-species together polarized the C-H bond,while the Au^(δ-)and O^-species jointly stabilized the CH_(3) intermediates,which favored the coupling of CH_(3) intermediate to photosynthesize C_(2)H_(6) instead of overoxidation into CO_(x).Thus,the design of dual active species is beneficial for achieving high-efficient CH_(4)-to-C_(2)H_(6) photoconversion. | Kai Zheng Xiaojing Zhang Jun Hu Chengbin Xu Juncheng Zhu Jing Li Mingyu Wu Shan Zhu Li Li Shumin Wang Yumei Lv Xin He Ming Zuo Chengyuan Liu Yang Pan Junfa Zhu Yongfu Sun Yi Xie | 2024 | Science China Chemistry2024，67，3： | 0 |
| 15 | Insights into Pyrolysis of Nano-Polystyrene Particles: Thermochemical Behaviors and Kinetics Analysis显示文摘The thermal degradation kinetics of nano-polystyrene particles with diameters of 60,90,160,and 225 nm were investigated in nitrogen atmosphere using thermogravimetric analysis(TGA).Various kinetic models were employed to determine the thermal degradation mechanism and kinetics.Nano-polystyrene particles have relatively lower thermal stability when compared to micro-polystyrene.Both differential thermo–gravimetric(DTG)data and apparent activation energies indicate that the thermal degradation of nano-polystyrene particles at 60 nm is a two-step reaction process where the second step plays a dominant role,while nano-polystyrene particles with diameter greater than 60 nm exhibit single-step degradation.Similar to most micro/macro polystyrene particles,DTG peaks of nano-polystyrene particles shift towards higher temperatures with increasing heating rates.Thermal degradation of nano-polystyrene particles under nitrogen atmosphere follows the first-order reaction model.However,the apparent activation energies increase(162-181 kJ·mol–1)with the increase of particle sizes(60-225 nm).This study could provide some insights into pyrolysis of nano-polystyrene particles and a safer process of manufacturing,storage and handling of nano-polystyrene particles. | DING Li ZHAO Jianping PAN Yong GUAN Jin JIANG Juncheng WANG Qingsheng | 2019 | Journal of Thermal Science2019，28，4： | 0 |
| 16 | Metal^(n+)-Metal^(δ+) pair sites steer C-C coupling for selective CO_(2) photoreduction to C_(2) hydrocarbons显示文摘The major obstacle for selective CO_(2)photoreduction to C_(2)hydrocarbons lies in the difficulty of C–C coupling,which is usually restrained by the repulsive dipole–dipole interaction between adjacent carbonaceous intermediates.Herein,we first construct semiconducting atomic layers featuring abundant Metal^(n+)-Metal^(δ+)pair sites(0<δ | Weiwei Shao Xiaodong Li Juncheng Zhu Xiaolong Zu Liang Liang Jun Hu Yang Pan Junfa Zhu Wensheng Yan Yongfu Sun Yi Xie | 2022 | Nano Research2022，15，3： | 0 |
| 17 | Boosting overall saline water splitting by constructing a strain-engineered high-entropy electrocatalyst显示文摘High-entropy materials(HEMs),which are newly manufactured compounds that contain five or more metal cations,can be a platform with desired properties,including improved electrocatalytic performance owing to the inherent complexity.Here,a strain engineering methodology is proposed to design transition-metal-based HEM by Li manipulation(LiTM)with tunable lattice strain,thus tailoring the electronic structure and boosting electrocatalytic performance.As confirmed by the experiments and calculation results,tensile strain in the LiTM after Li manipulation can optimize the d-band center and increase the electrical conductivity.Accordingly,the asprepared LiTM-25 demonstrates optimized oxygen evolution reaction and hydrogen evolution reaction activity in alkaline saline water,requiring ultralow overpotentials of 265 and 42 mV at 10 mA cm−2,respectively.More strikingly,LiTM-25 retains 94.6%activity after 80 h of a durability test when assembled as an anion-exchange membrane water electrolyzer.Finally,in order to show the general efficacy of strain engineering,we incorporate Li into electrocatalysts with higher entropies as well. | Ateer Bao Yaohang Gu Yuxuan Zhang Bowen Zhang Juncheng Wu Bo Ni Xiaoyan Zhang Haijun Pan Xiwei Qi | 2024 | Carbon Energy2024，6，2： | 0 |
| 18 | Atomically Precise Pd Species Accelerating CO_(2) Hydrodeoxygenation into CH_(4) with 100%Selectivity显示文摘High-rate CO_(2)-to-CH_(4)photoreduction with high selectivity is highly attractive,which is a win-win strategy for mitigating the greenhouse effect and the energy crisis.However,the poor photocatalytic activity and low product selectivity hinder the practical application.To precisely tailor the product selectivity and realize high-rate CO_(2)photoreduction,we design atomically precise Pd species supported on In_(2)O_(3)nanosheets.Taking the synthetic 1.30Pd/In_(2)O_(3)nanosheets as an example,the aberration-correction high-angle annular dark-field scanning transmission electron microscopy image displayed the Pd species atomically dispersed on the In_(2)O_(3)nanosheets.Raman spectra and X-ray photoelectron spectra established that the strong interaction between the Pd species and the In_(2)O_(3)substrate drove electron transfer from In to Pd species,resulting in electron-enriched Pd sites for CO_(2)activation.Synchrotronradiation photoemission spectroscopy demonstrated that the Pd species can tailor the conduction band edge of In_(2)O_(3)nanosheets to match the CO_(2)-to-CH_(4)pathway,instead of the CO_(2)-to-CO pathway,which theoretically accounts for the high CH_(4)selectivity.Moreover,in situ X-ray photoelectron spectroscopy unveiled that the catalytically active sites had a change from In species to Pd species over the 1.30Pd/In_(2)O_(3)nanosheets.In situ FTIR and EPR spectra reveal the atomically precise Pd species with rich electrons prefer to adsorb the electrophilic protons for accelerating the*COOH intermediates hydrogenation into CH_(4).Consequently,the 1.30Pd/In_(2)O_(3)nanosheets reached CO_(2)-to-CH_(4)photoconversion with 100%selectivity and 81.2μmol g^(−1)h^(−1)productivity. | Kai Zheng Siying Liu Bangwang Li Juncheng Zhu Xiaojing Zhang Mingyu Wu Li Li Shan Zhu Wenxiu Liu Jun Hu Chengyuan Liu Minghui Fan Ming Zuo Junfa Zhu Yang Pan Yongfu Sun Yi Xie | 2023 | Precision Chemistry2023，1，9： | 0 |
| 19 | Prediction of the flash points of alkanes by group bond contribution method using artificial neural networks显示文摘A group bond contribution model using artificial neural networks,which had the high ability of nonlinear of prediction,was established to predict the flash points of alkanes.This model contained not only the information of group property but also connectivity in molecules.A set of 16 group bonds were used as input parameters of neural networks to study the correlation of molecular structures with flash points of 44 alkanes.The results showed that the predicted flash points were in good agreement with the experi-mental data that the absolute mean absolute error was 6.9 K and the absolute mean relative error was 2.29%,which were superior to those of traditional group contribution methods.The method can be used not only to reveal the quantitative correlation between flash points and molecular structures of alkanes but also to predict the flash points of organic compounds for chemical engineering. | PAN Yong JIANG Juncheng WANG Zhirong | 2007 | Frontiers of Chemical Science and Engineering2007，1，4： | 0 |
