| 2 | Topotactic reduction of layered double hydroxides for atomically thick two-dimensional non-noble-metal alloy显示文摘Layered double hydroxides (LDHs) have been widely used as catalysts owingto their tunable structure and atomic dispersion of high-valence metal ions;however, limited tunability of electronic structure and valence states havehindered further improvement in their catalytic performance. Herein, we reducedultrathin LDH precursors in situ and topotactically converted them to atomicallythick (N2 nm) two-dimensional (2D) multi-metallic, single crystalline alloynanosheets with highly tunable metallic compositions. The as-obtained alloynanosheets not only maintained the vertically aligned ultrathin 2D structure,but also inherited the atomic dispersion of the minor metallic compositions ofthe LDH precursors, even though the atomic percentage was higher than 20%,which is far beyond the reported percentages for single-atom dispersions (usuallyless than 0.1%). Besides, surface engineering of the alloy nanosheets can finely tunethe surface electronic structure for catalytic applications. Such in situ topotacticconversion strategy has introduced a novel approach for atomically dispersedalloy nanostructures and reinforced the synthetic methodology for ultrathin 2Dmetal-based catalysts. | Pengsong Li Qixian Xie Lirong Zheng Guang Feng Yingjie Li Zhao Cai Yongmin Bi Yaping Li Yun Kuang Xiaoming Sun Xue Duan | 2017 | Nano Research2017，10，9： | 4 |
| 3 | Common-Ion Effect Triggered Highly Sustained Seawater Electrolysis with Additional NaCl Production显示文摘Developing efficient seawater-electrolysis system for mass production of hydrogen is highly desirable due to the abundance of seawater.However,continuous electrolysis with seawater feeding boosts the concentration of sodium chloride in the electrolyzer,leading to severe electrode corrosion and chlorine evolution.Herein,the common-ion effect was utilized into the electrolyzer to depress the solubility of NaCl.Specifically,utilization of 6M NaOH halved the solubility of NaCl in the electrolyte,affording efficient,durable,and sustained seawater electrolysis in NaCl-saturated electrolytes with triple production of H_(2),O_(2),and crystalline NaCl.Ternary NiCoFe phosphide was employed as a bifunctional anode and cathode in simulative and Ca/Mg-free seawater-electrolysis systems,which could stably work under 500 mA/cm^(2) for over 100 h.We attribute the high stability to the increased Na^(+)concentration,which reduces the concentration of dissolved Cl-in the electrolyte according to the common-ion effect,resulting in crystallization of NaCl,eliminated anode corrosion,and chlorine oxidation during continuous supplementation of Ca/Mg-free seawater to the electrolysis system. | Pengsong Li Shiyuan Wang Imran Ahmed Samo Xingheng Zhang Zhaolei Wang Cheng Wang Yang Li Yiyun Du Yang Zhong Congtian Cheng Wenwen Xu Xijun Liu Yun Kuang Zhiyi Lu Xiaoming Sun | 2020 | Research2020，，1： | 3 |
| 4 | Enhancing oxygen evolution reaction by cationic surfactants显示文摘Oxygen evolution reaction is critical for water splitting or metal-air batteries,but previous research mainly focuses on electrode material or structure optimization.Herein,we demonstrate that surfactant modification of a NiFe layered double hydroxide (LDH) array electrode,one of the best catalysts for oxygen evolution reaction (OER),could achieve superaerophobic surface with balanced surface charges,affording fast mass transfer,quick gas release,and boosted OER performance.The assembled surfactants on the electrode surface are responsible for lowering the bubble adhesive force (~ 1.03 μN) and corresponding fast release of small bubbles generated during OER.In addition,the bipolar nature of the hexadecyl trimethyl ammonium bromide (CTAB) molecule lead to bilayer assembly of the surfactants with the polar ends facing the electrode surface and the electrolyte,resulting in neutralized charges on the electrode surface.As a result,OH-transfer was facilitated and OER performance was enhanced.With the modified superaerophobic surface and balanced surface charge,NiFe LDHs-CTAB nanostructured electrode showed ultrahigh current density increase (9.39 mA(mV·cm^2)),2.3 times higher than that for conventional NiFe LDH nanoarray electrode),dramatically fast gas release,and excellent durability.The introduction of surfactants to construct under-water superaerophobic electrode with in-time repelling ability to the as-formed gas bubbles may open up a new pathway for designing efficient electrodes for gas evolution systems with potentially practical application in the near future. | Qixian Xie Daojin Zhou Pengsong Li Zhao Cai Tianhui Xie Tengfei Gao Ruida Chen Yun Kuang Xiaoming Sun | 2019 | Nano Research2019，12，9： | 3 |
| 5 | Control over π-π stacking of heteroheptacene-based nonfullerene acceptors for 16% efficiency polymer solar cells显示文摘Nonfullerene acceptors are being investigated for use in polymer solar cells(PSCs),with their advantages of extending the absorption range,reducing the energy loss and therefore enhancing the power conversion efficiency(PCE).However,to further boost the PCE,mobilities of these nonfullerene acceptors should be improved.For nonfullerene acceptors,the π-π stacking distance between cofacially stacked molecules significantly affects their mobility.Here;we demonstrate a strategy to increase the mobility of heteroheptacene-based nonfullerene acceptors by reducing their n'-7r stacking distances via control over the bulkiness of lateral side chains.Incorporation of 2-butyloctyl substituents into the nonfullerene acceptor(M36)leads to an increased mobility with a reduced π-π stacking distance of 3.45 A.Consequently,M36 affords an enhanced PCE of 16%,which is the highest among all acceptor-donor-acceptor-type nonfullerene acceptors to date.This strategy of control over the bulkiness of side chains on nonfullerene acceptors should aid the development of more efficient PSCs. | Yunlong Ma Dongdong Cai Shuo Wan Pan Yin Pengsong Wang Wenyuan Lin Qingdong Zheng | 2020 | National Science Review2020，7，12： | 2 |

| 7 | Density gradient ultracentrifugation for colloidal nanostructures separation and investigation显示文摘In this article,we review the advancement in nanoseparation and concomitant purification of nanoparticles(NPs) by using density gradient ultracentrifugation technique(DGUC) and demonstrated by taking several typical examples.Study emphasizes the conceptual advances in classification,mechanism of DGUC and synthesis-structure-property relationships of NPs to provide the significant clue for the further synthesis optimization.Separation,concentration,and purification of NPs by DGUC can be achieved at the same time by introducing the water/oil interfaces into the separation chamber.We can develop an efficient method ‘‘lab in a tube' by introducing a reaction zone or an assembly zone in the gradient to find the surface reaction and assembly mechanism of NPs since the reaction time can be precisely controlled and the chemical environment change can be extremely fast.Finally,to achieve the best separation parameters for the colloidal systems,we gave the mathematical descriptions and computational optimized models as a new direction for making practicable and predictable DGUC separation method.Thus,it can be helpful for an efficient separation as well as for the synthesis optimization,assembly and surface reactions as a potential cornerstone for the future development in the nanotechnology and this review can be served as a plethora of advanced notes on the DGUC separation method. | Pengsong Li Anuj Kumar Jun Ma Yun Kuang Liang Luo Xiaoming Sun | 2018 | Science Bulletin2018，63，10： | 1 |
| 8 | Intercepts allocation for layered defense显示文摘One important mission of the strategic defense is to develop an integrated, layered ballistic missile defense system(BMDS). Considering the problem of assigning limited defense weapons to incoming ballistic missiles, we illustrate how defense weapons, ballistic missiles, kill probability and effectiveness of defense(ED) are interrelated and how to understand this relationship for achieving the best allocation plan. Motivated by the queueing theory, in which the available resources are not sufficient to satisfy the demands placed upon them at all times, the layered deployed defense weapon is modeled as a queueing system to shoot Poisson arrived targets. Simultaneously, examples, of optimum intercepts allocation problems under different constraints are presented. The four theorems determine the allocation rules of intercepts to targets that maximize ED or minimize the cost to achieve a required ED. | Longyue Li Fuxian Liu Guangzheng Long Pengsong Guo Yingying Mei | 2016 | Journal of Systems Engineering and Electronics2016，27，3： | 0 |

| 10 | Development of a whole-cell biosensor based on an ArsR-Pars regulatory circuit from Geobacter sulfurreducens显示文摘In this study,an Escherichia coli(E.coli)whole-cell biosensor for the specific detection of bioavailable arsenic was developed by placing a green fluorescent protein(GFP)reporter gene under the control of the ArsR1(GSU2952)regulatory circuit from Geobacter sulfurreducens.E.coli cells only emitted green fluorescence in the presence of arsenite and were more sensitive to arsenite when they were grown in M9 supplemented medium compared to LB medium.Under optimal test conditions,the Geobacter arsR1 promoter had a detection limit of 0.01 mM arsenite and the GFP expression was linear within a range of 0.03-0.1 mM(2.25-7.5 mg/l).These values were well below World Health Organization’s drinking water quality standard,which is 10 mg/l.The feasibility of using this whole-cell biosensor to detect arsenic in water samples,such as arsenic polluted tap water and landfill leachate was verified.The biosensor was determined to be just as sensitive as atomic fluorescence spectrometry.This study examines the potential applications of biosensors constructed with Geobacter ArsR-Pars regulatory circuits and provides a rapid and cost-effective tool that can be used for arsenic detection in water samples. | Pengsong Li Yumingzi Wang Xin Yuan Xinying Liu Chunmao Liu Xiaofen Fu Dezhi Sun Yan Dang Dawn E.Holmes | 2021 | Environmental Science and Ecotechnology2021，，2： | 0 |

| 13 | Influence of span-to-depth ratio on dynamic response of vehicle-turnoutbridge system in high-speed railway显示文摘For high-speed railways,the smoothness of the railway line significantly affects the operational speed of trains.When the train passes through the turnout on a long-span bridge,the wheel-rail impacts caused by the turnout structure irregularities,and the instability arising from the bridge's flexural deformation lead to a strong coupling effect in the vehicle-turnout-bridge system.This significantly affects both ride comfort and operational safety.For addressing this issue,the present study considered a long-span continuous rigid-frame bridge as an example and established a train-turnout-bridge coupled dynamic model of high-speed railway.Utilizing a selfdeveloped dynamic simulation program,the study analysed the dynamic response characteristics when the train passes through the turnouts on the bridge.It also investigated the influence of different span-to-depth ratios of the bridge on the vehicle dynamic response when the train passes through the main line and branch line of turnouts and then proposed a span-to-depth ratio limit value for a long-span continuous rigid-frame bridge.The research findings suggest that the changes in the span-to-depth ratio have a relatively minor impact on the train’s operational performance but significantly affect the dynamic characteristics of the bridge structure.Based on the findings and a comprehensive assessment of safety indicators,it is advisable to establish a span-to-depth ratio limit of 1/4500 for a long-span continuous rigid-frame bridge. | Chuanqing Dai Tao Xin Shenlu Qiao Yanan Zhang Pengsong Wang Mahantesh M.Nadakatti | 2024 | High-Speed Railway2024，2，1： | 0 |
| 14 | Sm and S Co-doping to Construct Homo-hetero Cu Catalysts for Synergistic Enhancing CO_(2) Electroreduction显示文摘Copper(Cu)is recognized as one of the most efficient metal catalysts that can perform the electrocatalytic CO_(2) reduction reaction(CO_(2)RR)and its surface oxidation state determines the reaction pathway.The Cuδ+(0<δ<1)species,are well known active sites in CO_(2)RR to produce hydrocarbons and oxygenates.However,Cuδ+active sites are difficult to control,and it is very easy to be reduced to Cu^(0) under CO_(2)RR operating conditions.Herein,we report a homo-hetero doping strategy to construct an efficient samarium(Sm)and sulfur(S)co-doping catalyst(Smx-CuSy)for CO_(2)RR to formic acid(HCOOH).At optimum conditions,Smx-CuSy delivered a high HCOOH Faradaic efficiency(FE)of 92.1%at the current density of 300 mA·cm^(–2) using 1 mol/L KOH aqueous solution as electrolyte,and the reduction potential was as low as–0.52 V vs.reversible hydrogen electrode(RHE).The co-doping of Sm and S resulted in excellent CO_(2)RR performance owing to the synergistic effect of the homo-hetero structure.The homo-doping of S could effectively adjust the electronic structure of Cu in favor of the formation of abundant Cu^(δ+)species.The existence of hetero-Sm species could not only stabilize the Cu^(δ+)sites,but also increase the concentration of H ions to form a favorable catalytic environment for HCOOH generation. | Jiyuan Liu Pengsong Li Jiahui Bi Yong Wang Qinggong Zhu Xiaofu Sun Jianling Zhang Zhimin Liu Buxing Han | 2023 | Chinese Journal of Chemistry2023，41，12： | 0 |
