| 1 | Rational design of three-phase interfaces for electrocatalysis显示文摘Gas-involving electrochemical reactions,like oxygen reduction reaction (ORR),oxygen evolution reaction (OER),and hydrogen evolution reaction (HER),are critical processes for energy-saving,environment-friendly energy conversion and storage technologies which gain increasing attention.The development of according electrocatalysts is key to boost their electrocatalytic performances.Dramatic efforts have been put into the development of advanced electrocatalysts to overcome sluggish kinetics.On the other hand,the electrode interfaces-architecture construction plays an equally important role for practical applications because these imperative electrode reactions generally proceed at triple-phase interfaces of gas,liquid electrolyte,and solid electrocatalyst.A desirable architecture should facilitate the complicate reactions occur at the triple-phase interfaces,which including mass diffusion,surface reaction and electron transfer.In this review,we will summarize some design principles and synthetic strategies for optimizing triple-phase interfaces of gas-involving electrocatalysis systematically,based on the electrode reaction process at the three-phase interfaces.It can be divided into three main optimization directions:exposure of active sites,promotion of mass diffusion and acceleration of electron transfer.Furthermore,we especially highlight several remarkable works with comprehensive optimization about specific energy conversion devices,including metal-air batteries,fuel cells,and water-splitting devices are demonstrated with superb efficiency.In the last section,the perspectives and challenges in the future are proposed. | Yuqing Wang Yuqin Zou Li Tao Yanyong Wang Gen Huang Shiqian Du Shuangyin Wang | 2019 | Nano Research2019，12，9： | 10 |
| 2 | LDHs derived nanoparticle-stacked metal nitride as interlayer for long-life lithium sulfur batteries显示文摘Shuttle effect is one of the most serious disadvantages in lithium-sulfur battery which results in poor cycle performance and hinders the commercialization of Li-S battery.To reduce the dissolution of polysulfides into the electrolyte and prolong the cycling stability,nanoparticle-stacked metal nitride derived from layered double hydroxides(LDHs)as an interlayer was inserted between sulfur cathode and separator to confine polysulfides by physical and chemical interactions.Meanwhile,the surface of metal nitride will form an oxide passivation layer.The passivation layer possesses hydrophilic metal-O group and provides a polar surface for strong binding with polysulfide.What’s more,the nanoparticlesstacked structure could immerge and retain electrolyte well,which could enhance the ability of promoting the electron exchange rate.The sulfur electrode with nanoparticle-stacked metal nitride interlayer has an excellent cycle performance owing to the interactions between metal nitride and polysulfides.The battery delivered an initial capacity of 764.6 m Ahg^(-1) and still possesses a capacity of 477.5 mAhg^(-1) with the retention of 62.4% after 800 cycles. | Zhen Li Zhaoling Ma Yanyong Wang Ru Chen Zhenjun Wu Shuangyin Wang | 2018 | Science Bulletin2018，63，3： | 8 |

| 4 | Dehydrogenation of isobutane to isobutene over a Pt-Cu bimetallic catalyst in the presence of LaAlO_(3) perovskite显示文摘In this study,isobutane dehydrogenation to isobutene reaction was carried out in a series of PtCu bimetallic catalysts prepared by coimpregnation method.The catalysts were characterized by means of several techniques,including XRD,N_(2) adsorptiondesorption,TEM,XPS,H2TPR and TG.The results show that the existence of LaAlO_(3) perovskite can enhance the dispersion and sintering resistance of metal nanoparticles and facilitate the transfer of carbon deposits from active sites to the support.Interestingly,the perovskite nanoparticles can also inhibit the reduction of CuOx and the formation of PtCu alloys,resulting in the suitable interaction between Pt and Cu.The PtCu/LaAlO_(3)/SiO_(2)catalyst exhibits the optimal dehydrogenation performance with an isobutane conversion of 47%and isobutene selectivity of 92%after 310 min reaction,which was ascribed to the unique role of LaAlO_(3) perovskite as well as the appropriate PtCu interaction. | Yanyong Li Meng Ge Jiameng Wang Mengquan Guo Fanji Liu Mingxun Han Yanhong Xu Lihong Zhang | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 2 |
| 5 | Attributes reduct and decision rules optimization based on maximal tolerance classification in incomplete information systems with fuzzy decisions显示文摘A new approach to knowledge acquisition in incomplete information system with fuzzy decisions is proposed. In such incomplete information system, the universe of discourse is classified by the maximal tolerance classes, and fuzzy approximations are defined based on them. Three types of relative reducts of maximal tolerance classes are then proposed, and three types of fuzzy decision rules based on the proposed attribute description are defined. The judgment theorems and approximation discernibility functions with respect to them are presented to compute the relative reduct by using Boolean reasoning techniques, from which we can derive optimal fuzzy decision rules from the systems. At last, three types of relative reducts of the system and their computing methods are given. | Fang Yang Yanyong Guan Shujin Li Lei Du | 2010 | Journal of Systems Engineering and Electronics2010，21，6： | 1 |
| 6 | Reinforcement learning based energy efficient robot relay for unmanned aerial vehicles against smart jamming显示文摘Unmanned aerial vehicles(UAVs)with limited energy resources,severe path loss,and shadowing to the ground base stations are vulnerable to smart jammers that aim to degrade the UAV communication performance and exhaust the UAV energy.The UAV anti-jamming communication performance,such as the outage probability,degrades if the robot relay is not aware of the jamming policies and the UAV network topology.In this paper,we propose a robot relay scheme for UAVs against smart jamming,which combines reinforcement learning with a function approximation approach named tile coding,to jointly optimize the robot moving distance and relay power with the unknown jamming channel states and locations.The robot mobility and relay policy are chosen based on the received jamming power,the robot received signal quality,location and energy consumption,and the bit error rate of the UAV messages.We also present a deep reinforcement learning version for the robot with sufficient computing resources.It uses three deep neural networks to choose the robot mobility and relay policy with reduced sample complexity,so as to avoid exploring dangerous policies that lead to the high outage probability of the UAV messages.The network architecture of the three networks is designed with fully connected layers instead of convolutional layers to reduce the computational complexity,which is analyzed by theoretical analyses.We provide the performance bound of the proposed schemes in terms of the bit error rate,robot energy consumption and utility based on a game-theoretic study.Simulation results show that the performance of our proposed relay schemes,including the bit error rate,the outage probability,and the robot energy consumption outperforms the existing schemes. | Xiaozhen LU Jingfang JIE Zihan LIN Liang XIAO Jin LI Yanyong ZHANG | 2022 | Science China(Information Sciences)2022，65，1： | 1 |
| 7 | Recrystallization nucleation under close-setδphase in a nickel-based superalloy during annealing显示文摘Annealing is one of the most efficient heat treatment to refine the grain microstructure in metal alloys.Prior to the annealing,an aging treatment can be implemented to precipitate the second phases for more nucleation sites in deformed mixed grains during subsequent recrystallization.However,the underlying mechanism behind the second phases and recrystallization has not yet been fully understood.Taking a typical deformed nickel(Ni)-based(GH4169)superalloy as an exapmle,this research aims to clairfy the connections between the recrystallization and delta(δ)phase(Ni_(3)Nb) during annealing.All deformed samples were also treated by aging and then annealing.The results show that the microstructure and component ofδphase dominated the recrystallization nucleation in the Ni-based alloy.Moreover,there was the presence of theδphase interval limiting nucleation(PILN)andδphase protecting nucleation(PPN),when a high content of close-set phase was precipitated from the matrix.The PILN determined the primary condition for the recrystallization nucleation that happended at the interval ofδphase larger than the critical nucleation size.The peak nucleation occurred in the PPN,where the recrystallization nucleus were free of the penetration by the adjacent grains,before the nucleation incubation time was reached.Thus,a new feasible JNtheory was proposed to determine the maximum domain of recrystallization nucleation under close-set precipitated phases.All the possible nucleation sites were assumed under PPN in the JNtheory.As such,the original microstructure can be expected to design for the annealing via the aging process.A quantitative evaluation of recrystallization nucleation can also achieved in the Ni-based alloys during aging. | Guanqiang Wang Mingsong Chen Yongcheng Lin Hongbin Li Yuqiang Jiang Yanyong Ma Chengxu Peng Jinliang Cai Quan Chen | 2022 | Journal of Materials Science & Technology2022，，20： | 1 |

| 10 | Promoting surface reconstruction of NiFe layered double hydroxides via intercalating[Cr(C_(2)O_(4))_(3)]^(3-)for enhanced oxygen evolution显示文摘Rationally manipulating surface reconstruction of catalysts for water oxidation,inducing formation and dynamic accumulation of catalytically active centers still face numerous challenges.Herein,the introduction of[Cr(C_(2)O_(4))_(3)]^(3-)into NiFe LDHs by intercalation engineering to promote surface reconstruction achieves an advanced oxygen evolution reaction(OER)activity.In view of the weak electronegativity of Cr^(3+) in[Cr(C_(2)O_(4))_(3)]^(3-),the intercalation of[Cr(C_(2)O_(4))_(3)]^(3-)is expected to result in an electron-rich structure of Fe sites in NiFe LDHs,and higher valence state of Ni can be formed with the charge transfer between Fe and Ni.The optimized electronic structure of NiFe-[Cr(C_(2)O_(4))_(3)]^(3-)-LDHs with more active Ni^(3+) species and the expedited dynamic generation of Ni^(3+) (Fe)OOH phase during the OER process contributed to its excellent catalytic property,revealed by in situ X-ray absorption spectroscopy,Raman spectroscopy,and quasi-in situ X-ray photoelectron spectroscopy.With the modulated electronic structure of metal sites,NiFe-[Cr(C_(2)O_(4))_(3)]^(3-)-LDHs exhibited promoted OER property with a lower overpotential of 236 mV at the current density of 10 mA cm^(-2).This work illustrates the intercalation of conjugated anion to dynamically construct desired Ni^(3+) sites with the optimal electronic environment for improved OER electrocatalysis. | Yujie Wu Minglei Song Yu-Cheng Huang Chung-Li Dong Yingying Li Yuxuan Lu Bo Zhou Dongdong Wang Jianfeng Jia Shuangyin Wang Yanyong Wang | 2022 | Journal of Energy Chemistry2022，31，11： | 1 |

| 12 | A novel annealing method to uniformly refine deformed mixed grain microstructure of a solution-treated Ni-based superalloy显示文摘Increasing static recrystallization(SRX)nucleation rate and decreasing grain growth rate are the main ways to obtain uniform and fine grain microstructure by annealing treatment.However,it is contradictory to raise the SRX nucleation rate and reduce grain growth rate during isothermal annealing treatment.This is because the increase of the SRX nucleation rate needs to raise annealing temperature,while the decline of grain growth rate needs to reduce the annealing temperature.To solve the contradiction,a novel method named cooling recrystallization annealing treatment(CRT)is designed and verified.For the CRT,the relatively high annealing temperature in the primary stage can promote SRX nucleation,and the gradually decreased annealing temperature can reduce the growth rate of SRX grains.Besides,an aged treatment is first carried out to precipitate high content of theδphase before the CRT.Enoughδphases not only provide large numbers of sites for SRX nucleation but also limit the grain growth due to the pinning effect,especially in the primary high-temperature stage.The results show that the novel method can refine deformed mixed grain microstructure well when the suitable cooling rate,start and final recrystallization annealing temperatures are employed.The deformed mixed grain can be uniformly refined to an average size of 8.26μm with the route of 900℃×12 h+1020℃→970℃×20 min. | WANG GuanQiang CHEN MingSong LIN YongCheng LI HongBin ZENG WeiDong MA YanYong CAI JinLiang PENG ChengXu ZOU FenYang | 2021 | Science China(Technological Sciences)2021，64，8： | 1 |

| 15 | Reaction mechanism and kinetics of Criegee intermediate and hydroperoxymethyl formate显示文摘The reaction mechanism and kinetics of the simplest Criegee intermediate CH_(2)OO reaction with hydroperoxymethyl formate(HPMF)was investigated at high-level quantum chemistry calculations.HPMF has two reactive functional groups,-C(O)OH and-OOH.The calculated results of thermodynamic data and rate constants indicated that the insertion reactions of CH_(2) OO with-OOH group of HPMF were more favorable than the reactions of CH_(2)OO with-C(O)OH group.The calculated overall rate constant was 2.33×10^(−13) cm^(3)/(moleculesec)at 298 K and the rate constants decreased as the temperature increased from 200 to 480 K.In addition,we also proved the polymerization reaction mechanism between CH_(2)OO and-OOH of HPMF.This theoretical study interpreted the previous experimental results,and supplied the structures of the intermediate products that couldn’t be detected during the experiment. | Meifang Chen Shengrui Tong Zhen Wang Weiran Li Yanyong Xu Sufan Wang Maofa Ge | 2021 | Journal of Environmental Sciences2021，33，7： | 0 |

| 18 | Liquid-phase exfoliation of violet phosphorus for electronic applications显示文摘Large-scale production of two-dimensional(2D)materials still is a crucial point toward its practical applications.Violet phosphorus(VP)with a wide bandgap accelerates and broadens the potential applications of elemental phosphorus in optoelectronics.Here,we demonstrate the scalable production of solution-processable violet phosphorus flakes stably dispersed in several solvents.The exfoliated VP flakes exhibit thickness-dependent visible photoluminescence characteristics,which covers the shortcoming of black phosphorus.Meanwhile,the VP-based field-effect transistor reveals relatively competitive electrical properties to other liquid-phase exfoliated 2D materials.Our study paves the way for a wide range of applications of optical devices,energy storage,catalysis,and sodium batteries based on large-scale VP flakes. | Shenghuang Lin Wai Kin Lai Yanyong Li Wei Lu Gongxun Bai Shu Ping Lau | 2021 | SmartMat2021，2，2： | 0 |
| 19 | Point Cloud Processing Methods for 3D Point Cloud Detection Tasks显示文摘Light detection and ranging(LiDAR)sensors play a vital role in acquiring 3D point cloud data and extracting valuable information about objects for tasks such as autonomous driving,robotics,and virtual reality(VR).However,the sparse and disordered nature of the 3D point cloud poses significant challenges to feature extraction.Overcoming limitations is critical for 3D point cloud processing.3D point cloud object detection is a very challenging and crucial task,in which point cloud processing and feature extraction methods play a crucial role and have a significant impact on subsequent object detection performance.In this overview of outstanding work in object detection from the 3D point cloud,we specifically focus on summarizing methods employed in 3D point cloud processing.We introduce the way point clouds are processed in classical 3D object detection algorithms,and their improvements to solve the problems existing in point cloud processing.Different voxelization methods and point cloud sampling strategies will influence the extracted features,thereby impacting the final detection performance. | WANG Chongchong LI Yao WANG Beibei CAO Hong ZHANG Yanyong | 2023 | ZTE Communications2023，21，4： | 0 |
| 20 | Activating surface atoms of high entropy oxides for enhancing oxygen evolution reaction显示文摘High entropy oxides(HEOs) have attracted extensive attention of researchers due to their remarkable properties. The electrocatalytic activity of electrocatalysts is closely related to the reactivity of their surface atoms which usually shows a positive correlation. Excellenet stability of HEOs leads to their surface atoms with relative poor reactivity, limiting the applications for electrocatalysis. Therefore, it is significant to activate surface atoms of HEOs. Constructing amorphous structure, introducing oxygen defects and leaching are very effective strategies to improve the reactivity of surface atoms. Herein, to remove chemical inert, low-crystallinity(Fe, Co, Ni, Mn, Zn)_(3)O_(4) (HEO-Origin) nanosheets with abundant oxygen vacancies was synthesized, showing an excellent catalytic activity with an overpotential of 265 mV at 10 mA/cm^(2), which outperforms as-synthesized HEO-500℃-air(335 mV). The excellent catalytic performance of HEO-Origin can be attributed to high activity surface atoms, the introduction of oxygen defects efficiently altered electron distribution on the surface of HEO-Origin. Apart from, HEO-Origin also exhibits an outstanding electrochemical stability for oxygen evolution reaction(OER). | Mengyu Li Minglei Song Wenting Ni Zhaohui Xiao Yingying Li Jianfeng Jia Shuangyin Wang Yanyong Wang | 2023 | Chinese Chemical Letters2023，34，3： | 0 |
