| 2 | Insight of the stability and activity of platinum single atoms on ceria显示文摘Single-atom catalysts (SACs) have recently attracted broad attention in the catalysis field due to their maximized atom efficiency and unique catalytic properties.An atomic-level understanding of the interaction between the metal atoms and support is vital for developing stable and high-performance SACs.In this work,Pt1 single atoms with Ioadings up to 4 wt.% were fabricated on ceria nanorods using the atomic layer deposition technique.To understand the Pt-O-Ce bond interfacial interactions,the stability of Pt1 single atoms in the hydrogen reducing environment was extensively investigated by using in situ diffuse reflectance infrared Fourier transform spectroscopy CO chemisorption measurements.It was found that ceria defect sites,metal Ioadings and high-temperature calcination are effective ways to tune the stability of Pt1 single atoms in the hydrogen environment.X-ray photoemission spectroscopy further showed that Pt1 single atoms on ceria are dominantly at a +2 valence state at the defect and step edge sites,while those on terrace sites are at a +4 state.The above tailored stability and electronic properties of Pt1 single atoms are found to be strongly correlated with the catalytic activity in the dry and water-mediated CO oxidation reactions. | Xuxu Ye Hengwei Wang Yue Lin Xinyu Liu Lina Cao Jian Gu Junling Lu | 2019 | Nano Research2019，12，6： | 13 |
| 3 | Additive manufacturing of high-strength CrMnFeCoNi high-entropy alloys-based composites with WC addition显示文摘Laser melting deposition with WC addition has been developed to fabricate high-strength CrMnFeCoNibased high-entropy alloys-based composites.By this technique,a microstructure of compact refined equiaxed grains can be achieved,and the tensile strength can be remarkably improved.The sample with 5 wt%WC addition shows a promising mechanical performance with a tensile strength of 800 MPa and an elongation of 37%.The improvement in mechanical property may be attributed to the formation of Cr(23)C6 reinforcement precipitates,which could promote the heterogeneous nucleation of grains and hinder the propagation of slip bands. | Jinfeng Li Shuo Xiang Hengwei Luan Abdukadir Amar Xue Liu Siyuan Lu Yangyang Zeng Guomin Le Xiaoying Wang Fengsheng Qu Chunli Jiang Guannan Yang | 2019 | Journal of Materials Science & Technology2019，35，11： | 13 |
| 4 | A Review on Particle Size Effect in Metal-Catalyzed Heterogeneous Reactions显示文摘Size of metal nanoparticles(NPs)plays decisive roles in metal-catalyzed heterogeneous reactions,due to the drastic variation of the geometric and electronic properties of metal NPs with size.Along with the development of controlled catalyst synthesis,tremendous efforts have been devoted to understanding the nature of the particle size effect.In particular,identification of the individual roles of size-dependent geometric and electronic effects on metal-catalyzed reactions is essential,but remains challenging since they are tightly hybridized together with particle size variation.In this review,w e first discuss the fundamentals of the size-dependent geometric and electronic properties of metal NPs and their crucial roles in catalysis in general.Then we summarize the previous representative studies of the particle size effect,metal-by-metal,in heterogeneous catalysis.We highlighted the extension of particle size effect to ultrafine cluster and single-atom catalysts,the new frontiers in heterogeneous catalysis.In the followings,we further introduce the recent advances in disentangling the size-dependent geometric and electronic effects and unveiling their individual contributions to catalysis.Finally,we discuss the challenges and perspectives of investigations on the size effect in metal catalysis for the future studies. | Hengwei Wang Junling Lu | 2020 | Chinese Journal of Chemistry2020，38，11： | 5 |
| 5 | In Situ Synthesis of Fluorescent Mesoporous Silica–Carbon Dot Nanohybrids Featuring Folate Receptor-Overexpressing Cancer Cell Targeting and Drug Delivery显示文摘Multifunctional nanocarrier-based theranostics is supposed to overcome some key problems in cancer treatment.In this work,a novel method for the preparation of a fluorescent mesoporous silica–carbon dot nanohybrid was developed.Carbon dots(CDs),from folic acid as the raw material,were prepared in situ and anchored on the surface of amino-modified mesoporous silica nanoparticles(MSNs–NH2) via a microwave-assisted solvothermal reaction.The as-prepared nanohybrid(designated MSNs–CDs) not only exhibited strong and stable yellow emission but also preserved the unique features of MSNs(e.g.,mesoporous structure,large specific surface area,and good biocompatibility),demonstrating a potential capability for fluorescence imagingguided drug delivery.More interestingly,the MSNs–CDs nanohybrid was able to selectively target folate receptor-overexpressing cancer cells(e.g.,HeLa),indicating that folic acid still retained its function even after undergoing the solvothermal reaction.Benefited by these excellent properties,the fluorescent MSNs–CDs nanohybrid can be employed as a fluorescence-guided nanocarrier for the targeted deliveryof anticancer drugs(e.g.,doxorubicin),thereby enhancing chemotherapeutic efficacy and reducing side effects.Our studies may provide a facile strategy for the fabrication of multifunctional MSN-based theranostic platforms,which is beneficial in the diagnosis and therapy of cancers in future. | Shuai Zhao Shan Sun Kai Jiang Yuhui Wang Yu Liu Song Wu Zhongjun Li Qinghai Shu Hengwei Lin | 2019 | Nano-Micro Letters2019，11，2： | 5 |
| 6 | Green and Near-Infrared Dual-Mode Afterglow of Carbon Dots and Their Applications for Confidential Information Readout显示文摘Near-infrared(NIR),particularly NIR-containing dual-/multimode afterglow,is very attractive in many fields of application,but it is still a great challenge to achieve such property of materials. Herein,we report a facile method to prepare green and NIR dual-mode afterglow of carbon dots(CDs) through in situ embedding o-CDs(being prepared from o-phenylenediamine) into cyanuric acid(CA) matrix(named o-CDs@CA). Further studies reveal that the green and NIR afterglows of o-CDs@CA originate from thermal activated delayed fluorescence(TADF) and room temperature phosphorescence(RTP) of o-CDs,respectively. In addition,the formation of covalent bonds between o-CDs and CA,and the presence of multiple fixation and rigid e ects to the triplet states of o-CDs are confirmed to be critical for activating the observed dual-mode afterglow. Due to the shorter lifetime and insensitiveness to human vision of the NIR RTP of o-CDs@CA,it is completely covered by the green TADF during directly observing. The NIR RTP signal,however,can be readily captured if an optical filter(cut-o wavelength of 600 nm) being used. By utilizing these unique features,the applications of o-CDs@CA in anti-counterfeiting and information encryption have been demonstrated with great confidentiality. Finally,the as-developed method was confirmed to be applicable to many other kinds of CDs for achieving or enhancing their afterglow performances. | Yuci Wang Kai Jiang Jiaren Du Licheng Zheng Yike Li Zhongjun Li Hengwei Lin | 2021 | Nano-Micro Letters2021，13，12： | 4 |
| 7 | Enabling robust and hour-level organic long persistent luminescence from carbon dots by covalent fixation显示文摘The first carbon dot(CD)-based organic long persistent luminescence(OLPL)system exhibiting more than 1 h of duration was developed.In contrast to the established OLPL systems,herein,the reported CDs-based system(named m-CDs@CA)can be facilely and effectively fabricated using a household microwave oven,and more impressively,its LPL can be observed under ambient conditions and even in aqueous media.XRD and TEM characterizations,afterglow decay,time-resolved spectroscopy,and ESR analysis were performed,showing the successful composition of CDs and.CA,the formation of exciplexes and long-lived charged-separated states.Further studies suggest that the production of covalent bonds between CA and CDs plays pivotal roles in activating LPL and preventing its quenching from oxygen and water.To the best of our knowledge,this is a very rare example of an OLPL system that exhibits hourlevel afterglow under ambient conditions.Finally,applications of m-CDs@C.A in glow-in-the-dark paints for emergency signs and multicolored luminous pearls were preliminarily demonstrated.This work may provide new insights for the development of rare earth-free and robust OLPL materials. | Kai Jiang Yuci Wang Cunjian Lin Licheng Zheng Jiaren Du Yixi Zhuang Rongjun Xie Zhongjun Li Hengwei Lin | 2022 | Light(Science & Applications)2022，11，4： | 3 |
| 8 | Optimal Active Defence Using Dynamic Multi-Stage Signalling Game显示文摘Nowadays, security defence of network uses the game theory, which mostly applies complete information game model or even the static game model. To get closer to the actual network and defend actively, we propose a network attack-defence game model by using signalling game, which is modelled in the way of dynamic and incomplete information. We improve the traditional attack-defence strategies quantization method to meet the needs of the network signalling game model. Moreover, we give the calculation of the game equilibrium and analyse the optimal defence scheme. Finally, we analyse and verify effectiveness of the model and method through a simulation experiment. | ZHANG Hengwei LI Tao WANG Jindong HAN Jihong | 2015 | China Communications2015，12，S2： | 2 |
| 9 | Spatiotemporal Mapping of Salt Marshes in the Intertidal Zone of China during 1985-2019显示文摘This study mapped the areal extent,identified the species composition,and analyzed the changes of salt marshes in the intertidal zone of China during the period 1985–2019.With the aid of the cloud platform of the Google Earth Engine,we selected Landsat 5/8 and Sentinel-2 images and used the support vector machine classification method to extract salt marsh information for the years of 1985,1990,1995,2000,2005,2010,2015,and 2019.Seven major species of salt marshes:Phragmites australis,Suaeda spp.,Spartina alterniflora,Scirpus mariqueter,Tamarix chinensis,Cyperus malaccensis,and Sesuvium portulacastrum were identified.Our results showed that salt marshes are mainly distributed in Liaoning,Shandong,Jiangsu,Shanghai,and Zhejiang,with varying patterns of shrinking,expansion,or wavering in different places.The distribution of salt marshes has declined considerably from 151,324 ha in 1985 to 115,397 ha in 2019,a drop of 23.7%.During the same period,the area of native species has dropped 95.4%from 77,741 ha to 3,563 ha for Suaeda spp.and 45.1%from 60,511 ha to 33,193 ha for P.australis;on the contrary,the area of exotic species,S.alterniflora,has exhibited a sharp rise from just 99 ha to 67,527 ha.For the past 35 years,the driving factors causing salt marsh changes are mainly land reclamation,variations in water and sand fluxes,and interspecific competition and succession of salt marsh vegetation.These results provide fundamental reference information and could form the scientific basis for formulating policies for the conservation and utilization of salt marsh resources in China. | Guangwei Chen Runjie Jin Zhanjiang Ye Qi Li Jiali Gu Min Luo Yongming Luo George Christakos James Morris Junyu He Dan Li Hengwei Wang Li Song Qiuxuan Wang Jiaping Wu | 2022 | Journal of Remote Sensing2022，，1： | 2 |

| 11 | Mining cotton fiber strength candidate genes based on transcriptome mapping显示文摘Cotton fiber strength is mainly determined during the secondary cell wall (SCW) thickening stage. In 24―25 days post anthesis (DPA) of SCW thickening stage, cDNA-amplified fragment length polymorphism (AFLP) was carried out to construct fiber transcriptome groups. Based on these groups, cotton fiber strength candidate genes were detected by composite interval mapping (CIM) through quantitative trait locus (QTL) scanning. The mapping population was the interspecific backcross BC1 of Gossypium hirsutum × G. barbadense. One hundred and fifteen BC1 plants were used for group construction with 102 qualified absence/presence polymorphic transcript-derived fragments (TDFs) from G. barbadense, and 78 TDFs were assigned into eight transcriptome groups that gave a total length of 462.63 centimorgans (cM). Two significant QTLs, FS1 and FS2, were detected and explained 16.08% and 15.87% of fiber strength variance, respectively. Of the six TDFs co-segregating with FS1 and FS2, except one encoding an unknown protein, five targeted putative phosphatidylinositol kinase, trehalose-6 phosphate synthase, MADS transcription factor, cellulose synthase-like protein and phenylalanine ammonia lyase, respectively. These functional genes were involved in plant cell wall morphogenesis or cellulose synthesis metabolism processes, and were considered as the candidate genes controlling cotton fiber strength. | LIU HengWei WANG XingFen PAN YuXin SHI RuiFeng ZHANG GuiYin MA ZhiYing | 2009 | Chinese Science Bulletin2009，54，24： | 1 |

| 13 | Security Defence Policy Selection Method Using the Incomplete Information Game Model显示文摘Nowadays, the network defence policy selection using game model of incomplete information ignores the type of the defender, which quantifies cost simply, resulting in unreasonable defence policies selection. Aiming at the problem, we use Bayesian game theory to model the active defence policy selection. We take the types of both the attacker and the defender into consideration. Besides, the traditional quantization method is enhanced. Then, we calculate the equilibrium of static Bayesian game. Based on the analysis of the equilibrium, we select the optimal defence policy through the prediction for attackers' actions. The paper calculates the defence effectiveness of defence policies and provides a defence policies selection algorithm. Ultimately, we present an example to verify the effectiveness of the method and model proposed in the paper. | ZHANG Hengwei YU Dingkun WANG Jindong HAN Jihong WANG Na | 2015 | China Communications2015，12，S2： | 1 |

| 17 | CSFW-SC: Cuckoo Search Fuzzy-Weighting Algorithm for Subspace Clustering Applying to High-Dimensional Clustering显示文摘Aimed at the issue that traditional clustering methods are not appropriate to high-dimensional data, a cuckoo search fuzzy-weighting algorithm for subspace clustering is presented on the basis of the exited soft subspace clustering algorithm. In the proposed algorithm, a novel objective function is firstly designed by considering the fuzzy weighting within-cluster compactness and the between-cluster separation, and loosening the constraints of dimension weight matrix. Then gradual membership and improved Cuckoo search, a global search strategy, are introduced to optimize the objective function and search subspace clusters, giving novel learning rules for clustering. At last, the performance of the proposed algorithm on the clustering analysis of various low and high dimensional datasets is experimentally compared with that of several competitive subspace clustering algorithms. Experimental studies demonstrate that the proposed algorithm can obtain better performance than most of the existing soft subspace clustering algorithms. | WANG Jindong HE Jiajing ZHANG Hengwei YU Zhiyong | 2015 | China Communications2015，12，S2： | 1 |
