| 1 | Defect Engineering in 2D Materials: Precise Manipulation and Improved Functionalities显示文摘Two-dimensional(2D)materials have attracted increasing interests in the last decade.The ultrathin feature of 2D materials makes them promising building blocks for next-generation electronic and optoelectronic devices.With reducing dimensionality from 3D to 2D,the inevitable defects will play more important roles in determining the properties of materials.In order to maximize the functionality of 2D materials,deep understanding and precise manipulation of the defects are indispensable.In the recent years,increasing research efforts have been made on the observation,understanding,manipulation,and control of defects in 2D materials.Here,we summarize the recent research progress of defect engineering on 2D materials.The defect engineering triggered by electron beam(e-beam),plasma,chemical treatment,and so forth is comprehensively reviewed.Firstly,e-beam irradiation-induced defect evolution,structural transformation,and novel structure fabrication are introduced.With the assistance of a high-resolution electron microscope,the dynamics of defect engineering can be visualized in situ.Subsequently,defect engineering employed to improve the performance of 2D devices by means of other methods of plasma,chemical,and ozone treatments is reviewed.At last,the challenges and opportunities of defect engineering on promoting the development of 2D materials are discussed.Through this review,we aim to build a correlation between defects and properties of 2D materials to support the design and optimization of high-performance electronic and optoelectronic devices. | Jie Jiang Tao Xu Junpeng Lu Litao Sun Zhenhua Ni | 2019 | Research2019，，1： | 5 |
| 2 | Ultrasensitive graphene-Si position-sensitive detector for motion tracking显示文摘Motion tracking has attracted great attention in the fields of real-time tracking,nanorobotics,and targeted therapy.For achieving more accurate motion tracking,the highly sensitive position-sensitive detector(PSD)is desirable.Here,we demonstrate a meliorated PSD based on graphene-Si heterojunction for motion tracking.The position sensitivity of PSD was improved by employing surface engineering of graphene.Through modulating the transport property of graphene,nearly 20-fold increase of sensitivity was achieved under weak light,and at the same time,the detection limit power was reduced to^2 nW.A motion tracking system was developed based on the improved PSD,and human arm swing was tracked,which demonstrated high sensitivity and real-time tracking capabilities of the PSD.In addition,the PSD can support up to^10 kHz high-frequency tracking.This work provides a new strategy for improving the performance of PSD,and promotes the development of two-dimensional materials in novel optoelectronic devices. | Wenhui Wang Kaiyang Liu Jie Jiang Ruxia Du Litao Sun Wei Chen Junpeng Lu Zhenhua Ni | 2020 | InfoMat2020，2，4： | 3 |
| 3 | Polymer-derived SiBCN ceramic pressure sensor with excellent sensing performance显示文摘Pressure measurement with excellent stability and long time durability is highly desired,especially at high temperature and harsh environments.A polymer-derived silicoboron carbonitride(SiBCN)ceramic pressure sensor with excellent stability,accuracy,and repeatability is designed based on the giant piezoresistivity of SiBCN ceramics.The SiBCN ceramic sensor was packaged in a stainless steel case and tested using half Wheatstone bridge with the uniaxial pressure up to 10 MPa.The SiBCN ceramic showed a remarkable piezoresistive effect with the gauge factor(K)as high as 5500.The output voltage of packed SiBCN ceramic sensor changes monotonically and smoothly versus external pressure.The as received SiBCN pressure sensor possesses features of short response time,excellent repeatability,stability,sensitivity,and accuracy.Taking the excellent high temperature thermo-mechanical properties of polymer-derived SiBCN ceramics(e.g.,high temperature stability,oxidation/corrosion resistance)into account,SiBCN ceramic sensor has significant potential for pressure measurement at high temperature and harsh environments. | Gang SHAO Junpeng JIANG Mingjie JIANG Jie SU Wen LIU Hailong WANG Hongliang XU Hongxia LU Rui ZHANG | 2020 | Journal of Advanced Ceramics2020，9，3： | 3 |
| 4 | High valence metals engineering strategies of Fe/Co/Ni-based catalysts for boosted OER electrocatalysis显示文摘Electrocatalysis for the oxygen evolution reactions(OER)has attracted much attention due to its important role in water splitting and rechargeable metal-air batteries.Therefore,designing highly efficient and low-cost catalysts for OER process is essential as the conventional catalysts still rely on precious metals.Transition metal-based compounds have been widely investigated as active OER catalysts,and renewed interest in the high valence metals engineered compounds has been achieved for superior catalytic activity and stability.However,an in-depth understanding of the construction strategies and induced effects for the high valence metals engineered catalysts is still lacking and desired.In this review,we have summarized the construction strategies of high valence metals as dopants or formed heterostructures with the iron/cobalt/nickel(Fe/Co/Ni)-based catalysts.Then the induced effects on Fe/Co/Ni-based catalysts by incorporating high valence metals,e.g.,accelerating the surface reconstruction,forming amorphous structure,generating vacancies/defects,and acting as stabilizers,are highlighted.The impacts of high valence metals on OER performance are elucidated based on different elements,including molybdenum(Mo),tungsten(W),cerium(Ce),vanadium(V),chromium(Cr),manganese(Mn),niobium(Nb),zirconium(Zr).The correlations of construction strategies,induced effects,catalytic activity and OER reaction pathways are elaborated.Finally,the remaining challenges for further enhancements of OER performance induced by high valence metals are presented. | Lu Li Xianjun Cao Juanjuan Huo Junpeng Qu Weihua Chen Chuntai Liu Yufei Zhao Hao Liu Guoxiu Wang | 2023 | Journal of Energy Chemistry2023，，1： | 3 |

| 6 | How defects influence the photoluminescence of TMDCs显示文摘Two-dimensional(2D)transition metal dichalcogenide(TMDC)monolayers,a class of ultrathin materials with a direct bandgap and high exciton binding energies,provide an ideal platform to study the photoluminescence(PL)of light-emitting devices.Atomically thin TMDCs usually contain various defects,which enrich the lattice structure and give rise to many intriguing properties.As the influences of defects can be either detrimental or beneficial,a comprehensive understanding of the internal mechanisms underlying defect behaviour is required for PL tailoring.Herein,recent advances in the defect influences on PL emission are summarized and discussed.Fundamental mechanisms are the focus of this review,such as radiative/nonradiative recombination kinetics and band structure modification.Both challenges and opportunities are present in the field of defect manipulation,and the exploration of mechanisms is expected tofacilitate the applications of 2D TMDCs in the future. | Mengfan Zhou Wenhui Wang Junpeng Lu Zhenhua Ni | 2021 | Nano Research2021，14，1： | 2 |
| 7 | Bi_(2)O_(2)Se/BP van der Waals heterojunction for high performance broadband photodetector显示文摘Broadband photodetector has wide applications in the field of remote sensing,health monitoring and medical imaging.Two-dimensional(2D)materials with narrow bandgaps have shown enormous potential in broadband photodetection.However,the device performance is often restricted by the high dark currents.Herein,we demonstrate a high performance broadband photodetector by constructing Bi_(2)O_(2) Se/BP van der Waals heterojunction.The device exhibits a p-n diode behavior with a current rectification ratio of~20.Benifited from the low dark current of the heterojunction and the effective carrier separation,the device achieves the responsivity(R)of~500 A/W,~4.3 A/W and~2.3 A/W at 700 nm,1310 nm and 1550 nm,respectively.The specific detectivity(D^(*))is up to~2.8×10^(11) Jones(700 nm),~2.4×10^(9) Jones(1310 nm)and~1.3×10^(9) Jones(1550 nm).Moreover,the response time is~9 ms,which is more than 20 times faster than that of individual BP(~190 ms)and Bi_(2)O_(2)Se(~180 ms)devices. | Xing LIU Wenhui WANG Fang YANG Shaopeng FENG Zhenliang HU Junpeng LU Zhenhua NI | 2021 | Science China(Information Sciences)2021，64，4： | 2 |

| 9 | Reappraise role of lymph node status in patterns of recurrence following curative resection of gastric adenocarcinoma显示文摘Objective: To examine the association between lymph node status and recurrence patterns in completely resected gastric adenocarcinoma.Methods: We retrospectively assessed 1,694 patients who underwent curative gastrectomy from January 2010 to August 2014. Patients stratified according to lymph node status and recurrence patterns among different subgroups were compared.Results: Of all, 517(30.5%) patients developed recurrent disease, and complete data of recurrence could be obtained in 493(95.4%) patients. For p^(N0) patients, the patterns of recurrence were different according to p T stage: locoregional recurrence was most common in patients with p T1-2 disease(57.1%), distant recurrence was most common in patients with p T3 disease(57.1%), and peritoneal recurrence was most common in patients with p T4 a disease(66.7%). For p^(N+) patients, distant metastasis was most common pattern irrespective of p T stage. The site-specific trend of recurrence showed that locoregional recurrence increased within 5 years in patients with p^(N0)-2 disease but plateaued 3 years after surgery in patients with p N3 disease. Time to recurrence was significantly longer for the p^(N0) patients compared with the p^(N+) patients(median: 25 vs. 16 months, P=0.001).Moreover, post-recurrence survival was significantly better for the p^(N0) patients than for the p^(N+) patients(median:12 vs. 6 months, P<0.001), especially in patients with non-peritoneal recurrence, late recurrence, single recurrence,and receipt of potential curative treatment.Conclusions: Among clinicopathologic factors, lymph node status is the most important factor associated with recurrence patterns after curative gastrectomy. Lymph node status may be used as an adjunct in clinical decisionmaking about postoperative therapeutic and follow-up strategies. | Yihui Tang Jianxian Lin Junpeng Lin Jiabin Wang Jun Lu Qiyue Chen Longlong Caolj Mi Lin Ruhong Tu Changming Huang Ping Li Chaohui Zheng Jianwei Xie | 2021 | Chinese Journal of Cancer Research2021，33，3： | 1 |
| 10 | Electrochemical Carbon Dioxide Reduction to Ethylene:From Mechanistic Understanding to Catalyst Surface Engineering显示文摘Electrochemical carbon dioxide reduction reaction(CO_(2)RR)provides a promising way to convert CO_(2)to chemicals.The multicarbon(C_(2+))products,especially ethylene,are of great interest due to their versatile industrial applications.However,selectively reducing CO_(2)to ethylene is still challenging as the additional energy required for the C–C coupling step results in large overpotential and many competing products.Nonetheless,mechanistic understanding of the key steps and preferred reaction pathways/conditions,as well as rational design of novel catalysts for ethylene production have been regarded as promising approaches to achieving the highly efficient and selective CO_(2)RR.In this review,we first illustrate the key steps for CO_(2)RR to ethylene(e.g.,CO_(2)adsorption/activation,formation of~*CO intermediate,C–C coupling step),offering mechanistic understanding of CO_(2)RR conversion to ethylene.Then the alternative reaction pathways and conditions for the formation of ethylene and competitive products(C_1 and other C_(2+)products)are investigated,guiding the further design and development of preferred conditions for ethylene generation.Engineering strategies of Cu-based catalysts for CO_(2)RR-ethylene are further summarized,and the correlations of reaction mechanism/pathways,engineering strategies and selectivity are elaborated.Finally,major challenges and perspectives in the research area of CO_(2)RR are proposed for future development and practical applications. | Junpeng Qu Xianjun Cao Li Gao Jiayi Li Lu Li Yuhan Xie Yufei Zhao Jinqiang Zhang Minghong Wu Hao Liu | 2023 | Nano-Micro Letters2023，15，10： | 1 |

| 15 | 3个小型高原湖泊水陆交错带中植物叶片pH值变异及其潜在影响因素显示文摘陆生植物叶片pH值是与植物生理功能和养分利用状况息息相关的重要植物属性,并随植物功能型和环境的变化而变化。然而,水生植物叶片pH值的变异特征及其与陆生植物间的差异性仍不清楚。在3个自然形成的小型高原湖泊的湖滨植物群落中,我们采集植物、土壤和湖水样品,检测了植物叶片pH值与碳、氮含量以及环境条件(水或土壤pH值、土壤水位状况)。从植物功能型和群落两个水平分析了湖滨植物叶pH值沿水分梯度的变化及其潜在影响因素。研究结果表明,不同类型的水生植物,以及水生、沼生和陆生环境中生长的植物的叶pH存在较大差异;浮叶植物叶片pH值(4.21±0.05)显著低于挺水植物(5.71±0.07)和沉水植物(5.82±0.06);水生草本植物叶片pH值(5.43±0.10)显著低于沼生草本植物(6.12±0.07)和陆生草本植物(5.74±0.05);陆生草本植物叶片pH值显著高于木本植物。植物功能群间叶片pH值的变异可能与叶片的结构、光利用特性和养分特性有关。群落水平的结果与植物功能型水平相一致:水生群落叶片pH值显著低于陆生群落。群落水平叶片pH值可能主要受物种组成、水分条件和环境pH值的影响。本研究首次探索了水生植物的pH值,并且在景观尺度上对比了不同功能型植物的叶片pH值,为深入探索植物pH值变异机制以及其在水生和湿地生态系统中的生态意义提供参考。 | Sining Liu Shenqun An Zhengbing Yan Junpeng Ren Xiaoqian Lu Feiyang Ge Wenxuan Han | 2021 | Journal of Plant Ecology2021，14，3： | 1 |

| 18 | Effects of SnO on Structure and Propertiesof Borosilicate Glasses显示文摘Tin was found in the bottom of float borosilicate glasses.To simulate the enriched amounts of SnO found on the surface of the float borosilicate glasses,a series of glasses were produced in which the stannous concentration was varied from 0.1 wt% to 9.0 wt%,while the relative concentration of other components were held constant.Infrared spectra were obtained to probe the effect of increased amounts of SnO on the structure of the glass samples.The results show that SnO plays the role of an intermediate in glasses studied.When FO/SnO>1.0,SnO takes the role of network-former.And when FO/SnO<1.0,SnO can give the free oxygen as network-modifier.Besides,SnO has intensive effect on thermal performance of borosilicate glasses. | LU Ping CHENG Jinshu WAN Junpeng | 2008 | Journal of Wuhan University of Technology(Materials Science)2008，23，4： | 0 |
| 19 | A Coil Constant Calibration Method Based on the Phase-Frequency Response of Alkali Atomic Magnetometer显示文摘We propose an in-situ method to calibrate the coil constants of the optical atomic magnetomete. This method is based on measuring the Larmor precession of spin polarized alkali metal atoms and has been demonstrated on a K-Rb hybrid atomic magnetomete. Oscillation fields of different frequencies are swept on the transverse coil. By extracting the resonance frequency through phase-frequency analysis of electron spin projection, the coil constants are calibrated to be 323.1±0.28 nT/mA, 108±0.04nT/Ma, and 185.8±1.03 nT/mA along the X,Y, and Z directions, respectively. | Danyue MA Junpeng ZHAO Jixi LU Ming DING | 2019 | Photonic Sensors2019，9，2： | 0 |
| 20 | Tuning photoresponse of graphene-black phosphorus heterostructure by electrostatic gating and photo-induced doping显示文摘Metal-semiconductor diodes constructed from two-dimensional(2D)van der Waals heterostructures show excellent gate electrostatics and a large built-in electric field at the tunnel junction,which can be exploited to make highly sensitive photodetector.Here we demonstrate a metal-semiconductor photodiode constructed by the monolayer graphene(Gr)on a few-layer black phosphorus(BP).Due to the presence of a built-in potential barrier(~0.09±0.03 eV)at the Gr-BP interface,the photoresponsivity of the Gr-BP device is enhanced by a factor of 672%,and the external quantum efficiency(EQE)increases to648%from 84%of the bare BP.Electrostatic gating allows the BP channel to be switched between p-type and n-type conduction.We further demonstrate that excitation laser power can be used to control the current polarity of the Gr-BP device due to photon-induced doping.The versatility of the Gr-BP junctions in terms of electrostatic bias-induced or light-induced switching of current polarity is potentially useful for making dynamically reconfigurable digital circuits. | Yanpeng Liu Ming Yang Junpeng Lu Ying Liu Hongwei Liu Erwen Zhang Wei Fu Junyong Wang Zhenliang Hu Jun Yin Goki Eda Shijie Wang Jiabao Yi Ajayan Vinu Kian Ping Loh | 2022 | Chinese Chemical Letters2022，33，1： | 0 |
