| 1 | Combustion characteristics of semicokes derived from pyrolysis of low rank bituminous coal显示文摘Various semicokes were obtained from medium-low temperature pyrolysis of Dongrong long flame coal.The proximate analysis,calorific value and Hardgrove grindability index(HGI) of semicokes were determined,and the ignition temperature,burnout temperature,ignition index,burnout index,burnout ratio,combustion characteristic index of semicokes were measured and analyzed using thermogravimetry analysis(TGA).The effects of pyrolysis temperature,heating rate,and pyrolysis time on yield,composition and calorific value of long flame coal derived semicokes were investigated,especially the influence of pyrolysis temperature on combustion characteristics and grindability of the semicokes was studied combined with X-ray diffraction(XRD) analysis of semicokes.The results show that the volatile content,ash content and calorific value of semicokes pyrolyzed at all process parameters studied meet the technical specifications of the pulverized coal-fired furnaces(PCFF) referring to China Standards GB/T 7562-1998.The pyrolysis temperature is the most influential factor among pyrolysis process parameters.As pyrolysis temperature increases,the yield,ignition index,combustion reactivity and burnout index of semicokes show a decreasing tend,but the ash content increases.In the range of 400 and 450 °C,the grindability of semicokes is rational,especially the grindability of semicokes pyrolyzed at 450 °C is suitable.Except for the decrease of volatile content and increase of ash content,the decrease of combustion performance of semicokes pyrolyzed at higher temperature should be attributed to the improvement of the degree of structural ordering and the increase of aromaticity and average crystallite size of char.It is concluded that the semicokes pyrolyzed at the temperature of 450 °C is the proper fuel for PCFF. | Qian wei Xie Qiang Huang Yuyi Dang Jiatao Sun Kaidi Yang Qian Wang Jincao | 2012 | International Journal of Mining Science and Technology2012，22，5： | 10 |

| 4 | RuO_(2) clusters derived from bulk SrRuO_(3):Robust catalyst for oxygen evolution reaction in acid显示文摘Developing highly efficient oxygen evolution reaction(OER)catalyst for the acidic corrosive operating conditions is a challenging task.Herein,we report the synthesis of uniform RuO_(2)clusters with~2 nm in size via electrochemical leaching of Sr from SrRuO_(3) ceramic in acid.The RuO_(2)clusters exhibit ultrahigh OER activity with overpotential of~160 mV at 10 mA·cm_(geo)^(−2) in 1.0 M HClO4 solution for 30-h testing.The extended X-ray absorption fine structure measurement reveals enlarged Jahn-Teller distortion of Ru-O octahedra in the RuO_(2)clusters compared to its bulk counterpart.Density function theory calculations show that the enhanced Jahn-Teller distortion can improve the intrinsic OER activity of RuO_(2). | Muwei Ji Xin Yang Shengding Chang Wenxing Chen Jin Wang Dongsheng He Yao Hu Qian Deng You Sun Bo Li Jingyu Xi Tomoaki Yamada Jiatao Zhang Hai Xiao Caizhen Zhu Jia Li Yadong Li | 2022 | Nano Research2022，15，3： | 2 |
| 5 | Assembly-promoted photocatalysis:Three-dimensional assembly of CdS_(x)Se_(1-x)(x=0-1) quantum dots into nanospheres with enhanced photocatalytic performance显示文摘In this paper,through an emulsion-based bottom-up self-assembly method,monodisperse CdS_(x)Se_(1-x)(x=0-1)quantum dots(QDs)with tailoring compositions have been three-dimensionally assembled into spherical architectures in sub-micrometer sizes.UVeVis absorption measurements revealed the enhanced light harvesting abilities of the assembled CdS_(x)Se_(1-x) spheres relative to their constituting QDs.HRTEM characterizations over the CdS_(x)Se_(1-x) assemblies suggested the existence of localized oriented adjoining of the CdS_(x)Se_(1-x) QDs and the resulting nano-twin structures that are favorable for photogenerated electron-hole separation.The quenching of photoluminescence and the improvement in IPCE after the assembly of CdS_(x)Se_(1-x) QDs provided a clue to the likely suppressed electron-hole recombination brought about by the unique architectures and interfaces derived from self-assembly.The above findings were coincided with the remarkably improved H2 evolution activities observed for the wellassembled CdS_(x)Se_(1-x) nanospheres in photocatalytic water splitting,underpinning the importance of the alternative strategy to design advanced semiconductor photocatalysts based on architectural engineering. | Lina Wang Qiumei Di Mingming Sun Jia Liu Chuanbao Cao Jiajia Liu Meng Xu Jiatao Zhang | 2017 | Journal of Materiomics2017，3，1： | 2 |

| 9 | Monolayer puckered pentagonal VTe_(2):An emergent two-dimensional ferromagnetic semiconductor with multiferroic coupling显示文摘Two-dimensional(2D)magnetic crystals have been extensively explored thanks to their potential applications in spintronics,valleytronics,and topological superconductivity.Here we report a novel monolayer magnet,namely puckered pentagonal VTe_(2)(PP-VTe_(2)),intriguing atomic and electronic structures of which were firmly validated from first-principles calculations.The PP-VTe_(2) exhibits strong intrinsic ferromagnetism and semiconducting property distinct from the half-metallic bulk pyrite VTe_(2)(BP-VTe_(2))phase.An unusual magnetic anisotropy with large magnetic exchange energies is found.More interestingly,the multiferroic coupling between its 2D ferroelasticity and in-plane magnetization is further identified in PP-VTe_(2),lending it unprecedented controllability with external strains and electric fields.Serving as an emergent 2D ferromagnetic semiconductor with a novel crystal structure,monolayer PP-VTe_(2) provides an ideal platform for exploring exotic crystalline and spin configurations in low-dimensional systems. | Xuanyi Li Zhili Zhu Qing Yang Zexian Cao Yeliang Wang Sheng Meng Jiatao Sun Hong-Jun Gao | 2022 | Nano Research2022，15，2： | 0 |
| 10 | Computer Simulation on Temperature Rise in Process of Wire Drawing显示文摘In high speed wire drawing, the temperature rise is produced by the generation heat from plastic deformation of metal material and friction between wire and tool, which greatly influences the lubrication situation and mechanical properties. During high drawing, the phenomenon that wire is embrittled and die is stuck can be formed by the notable temperature rise. In this paper, based on theory of plastic deformation work , considering friction heat generation and variable physical coefficients, the mathematical model of temperature rise of high speed drawing is established and the computer program to analogy the whole process of drawing is compiled. Also the process of wire drawing on a few of alloys are calculated theoretically. Compared the calculation value with measurement, the result shows that the theoretical value coincides with experimental data. | Jiatao zhang, jialin Sun, Jinming Long, Shuixing Tang Kunming University of Science and Technology, Kunming , 650093, China | 2000 | Journal of Shanghai Jiaotong university(Science)2000，5，1： | 0 |
| 11 | Quantum nutcracker for near-room-temperature H_2 dissociation显示文摘Solid surfaces are well known to mediate the dissociation of molecules via electronic interactions (heterogeneous catalysis).In particular,H2 dissociation on metal surfaces has been widely studied for several decades because it is an important step in hydrogenation reactions.The efficiency of the process depends on both the electronic properties of the metal surface and the surface microstructures [1].Enhanced efficiency and reduced cost are usually achieved by using nanoparticles,which have increased the surface-to-volume ratio and low-coordination atoms [2].Another approach is to optimize the local electronic states of the metal surface by doping [3],alloying with other elements [4],or by taking advantage of strong interactions between metal nanoparticles and the supporting substrate [5].These methods often work together to tailor the adsorption properties on surfaces and show major efficiency enhancement. | Lei Tao Wei Guo Yu-Yang Zhang Yan-Fang Zhang Jiatao Sun Shixuan Du Sokrates T.Pantelides | 2019 | Science Bulletin2019，64，1： | 0 |
| 12 | Fabrication and manipulation of nanosized graphene homojunction with atomically-controlled boundaries显示文摘Controlling the atomic configurations of structural defects in graphene nanostructures is crucial for achieving desired functionalities.Here,we report the controlled fabrication of high-quality single-crystal and bicrystal graphene nanoislands(GNI)through a unique top-down etching and post-annealing procedure on a graphite surface.Low-temperature scanning tunneling microscopy(STM)combined with density functional theory calculations reveal that most of grain boundaries(GBs)formed on the bicrystal GNIs are 5-7-5-7 GBs.Two nanodomains separated by a 5-7-5-7 GB are AB stacking and twisted stacking with respect to the underlying graphite substrate and exhibit distinct electronic properties,forming a graphene homojunction.In addition,we construct homojunctions with alternative AB/twisted stacking nanodomains separated by parallel 5-7-5-7 GBs.Remarkably,the stacking orders of homojunctions are manipulated from AB/twist into twist/twist type through a STM tip.The controllable fabrication and manipulation of graphene homojunctions with 5-7-5-7 GBs and distinct stacking orders open an avenue for the construction of GBs-based devices in valleytronics and twistronics. | Hui Chen De-Liang Bao Dongfei Wang Yande Que Wende Xiao Yu-Yang Zhang Jiatao Sun Shixuan Du Hong-Jun Gao | 2020 | Nano Research2020，13，12： | 0 |
| 13 | Intriguing one-dimensional electronic behavior in emerging two-dimensional materials显示文摘Tomonaga-Luttinger liquid(TLL),a peculiar one-dimensional(1D)electronic behavior due to strong correlation,was first studied in 1D nanostructures and has attracted significant attention over the last several decades.With the rise of new two-dimensional(2D)quantum materials,1D nanostructures in 2D materials have provided a new platform with a well-defined configuration at the atomic scale for studying TLL electronic behavior.In this paper,we review the recent progress of TLL electronic features in emerging 2D materials embedded with various 1D nanostructures,including island edges,domain walls,and 1D moirépatterns.Specifically,novel physical phenomena,such as 1D edge states in 2D transition metal dichalcogenides(TMDs),helical TLL in 2D topological insulators(2DTI),and chiral TLL in 2D quantum Hall systems,are described and discussed at the nanoscale.We also analyze challenges and opportunities at the frontier of this research area. | Xuan Song Teng Zhang Huixia Yang Hongyan Ji Jiatao Sun Liwei Liu Yeliang Wang Hongjun Gao | 2021 | Nano Research2021，14，11： | 0 |

| 15 | Inhibitory Effects of 12 Chemical Agents against Alternaria alternata显示文摘[Objective]The paper was to screen highly efficient fungicides for the prevention and control of tobacco brown spot(Alternaria alternata).[Method]The inhibitory effects of 12 chemical agents against A.alternata were determined indoors by mycelium growth rate method.[Result]Toxicity test showed that 30%kresoxim-methyl·boscalid SC had the best inhibitory effect,with an EC_(50)of 1.05μg/mL,followed by 9%pyraclostrobin CS,with an EC_(50)of 2.09μg/mL.As a broad spectrum protective fungicide,77%copper calcium sulfate WP showed a low sensitivity against A.alternata in the petri dish test since it had a mechanism of action different from that of other chemical agents.[Conclusion]The study lays the foundation for subsequent screening of fungicides for the prevention and control of A.alternata in the field. | Shen Hong Zhang Jiatao Cui Zhiyan Sun Guangjun Li Bin Zhang Yongfeng Xu Chuantao Ai Yongfeng Song Guanglong Ji Xiuting Wang Xiaoqiang | 2020 | Plant Diseases and Pests2020，11，4： | 0 |
| 16 | Olefin-linked covalent organic frameworks with twisted tertiary amine knots for enhanced ultraviolet detection显示文摘Though Olefin-linked covalent organic frameworks(oCOFs)possess excellentπ-electron delocalization,the barely reversible olefin linkage brings challenges for oCOFs’synthesis and functionalization.Here,we synthesize new oCOFs with tertiary amine knots which have twisted configuration and electron-donating nature.Investigation into the structural variation and photoelectric performance shows that the twisted configuration of oCOF-TFPA could favor to the intramolecular charge transfer process and reduce the pos-sibility of aggregation-caused quenching.Photoelectrical measurements and electric band structure cal-culation both verify the superiority of this oCOFs’structure in photoelectric sensing. | Qianying Guo Hongyan Ji Lei Yang Daizong Ji Zhaolin Ai Shi Luo Jiatao Sun Yunqi Liu Dacheng Wei | 2022 | Chinese Chemical Letters2022，33，5： | 0 |
| 17 | Direct evidence of two-dimensional electron gas-like band structures in hafnene显示文摘Two-dimensional(2D)honeycomb-like materials have been widely studied due to their fascinating properties.In particular,2D honeycomb-like transition metal monolayers,which are good 2D ferromagnet candidates,have attracted intense research interest.The honeycomb-like structure of hafnium,hafnene,has been successfully fabricated on the Ir(111)substrate.However,its electronic structure has not yet been directly elucidated.Here,we report the electronic structure of hafnene grown on the Ir(111)substrate using angle-resolved photoemission spectroscopy(ARPES).Our results indicate that the presence of spin-orbit coupling and Hubbard interaction suppresses the earlier predicted Dirac cones at the K points of the Brillouin zone.The observed band structure of hafnene near the Fermi level is very simple:an electron pocket centered at theΓpoint of the Brillouin zone.This electron pocket shows typical parabolic dispersion,and its estimated electron effective mass and electron density are approximately 1.8_(me)and 7×10^(14)cm^(-2),respectively.Our results demonstrate the existence of 2D electron gas in hafnene grown on the Ir(111)substrate and therefore provide key information for potential hafnene-based device applications. | Shaozhu Xiao Meng Liu Linfei Li Jiatao Sun Yeliang Wang Shaolong He | 2022 | Nano Research2022，15，4： | 0 |
