| 1 | On the localised corrosion of carbon steel induced by the in-situ local damage of porous corrosion products显示文摘The effect of in-situ local damage of uniform porous corrosion products on the localised corrosion of carbon steel is investigated using the wire beam electrode technique(WBE)combined with morphology characterisation and electrochemical tests.The WBE measurements demonstrate that the localised corrosion is enhanced by the in-situ local removal of porous corrosion products,supported by the morphology characterisation and electrochemical tests.The enhanced localised corrosion does not originate from the damaged wire in WBE where the corrosion products are removed but from the other undamaged wires,which is reported for the first time.A mechanism is proposed that the intensive anodic polarisation effect of the damaged wire on the undamaged wires could account for the enhanced localised corrosion,which is due to the protective corrosion products newly formed on the damaged surface and the increase in the potential of damaged wire. | Lin Pang Zhengbin Wang Yugui Zheng Xueming Lai Xu Han | 2020 | Journal of Materials Science & Technology2020，54，19： | 4 |
| 2 | A high-efficient triboelectric-electromagnetic hybrid nanogenerator for vibration energy harvesting and wireless monitoring显示文摘Scavenging mechanical vibration energy by combining triboelectric nanogenerators(TENGs) and electromagnetic generators(EMGs) is a renewable and low-carbon way to generate electric power. In this paper, we fabricate a cylindrical structure hybrid nanogenerator based on spring structure to effectively scavenge vibration energy. The introduction of spring structure not only enhances the space utilization, but also supports the moving magnet. Owing to its innovative structure, the instantaneous output power of TENG and EMG are 0.88 mW at a load of 10 MΩ and 216.7 mW at a load of 60 Ω, respectively. With the aids of a power management circuit, the hybrid nanogenerator can provide continuous power for two hygrothermographs connected in series. In addition, a self-powered wireless acceleration sensing monitoring system(SWAM) is developed to measure the acceleration signals of vibration sources. This study provides a novel guideline for harvesting mechanical vibration energy. | Jian HE Xueming FAN Dongyang ZHAO Min CUI Bing HAN Xiaojuan HOU Xiujian CHOU | 2022 | Science China(Information Sciences)2022，65，4： | 3 |
| 3 | Boosted photoreduction of diluted CO_(2) through oxygen vacancy engineering in NiO nanoplatelets显示文摘Converting carbon dioxide(CO_(2))to diverse value-added products through photocatalysis can validly alleviate the critical issues of greenhouse effect and energy shortages simultaneously.In particular,based on practical considerations,exploring novel catalysts to achieve efficient photoreduction of diluted CO_(2) is necessary and urgent.However,this process is extremely challenging owing to the disturbance of competitive adsorption at low CO_(2) concentration.Herein,we delicately synthesize oxygen vacancy-laden NiO nanoplatelets(r-NiO)via calcination under Ar protection to reduce diluted CO_(2) through visible light irradiation(>400 nm)assisted by a Ru-based photosensitizer.Benefitting from the strongly CO_(2) adsorption energy of oxygen vacancies,which was confirmed by density functional calculations,the r-NiO catalysts exhibit higher activity and selectivity(6.28×10^(3)µmol·h^(−1)·g^(−1);82.11%)for diluted CO_(2)-to-CO conversion than that of the normal NiO(3.94×10^(3)µmol·h^(−1)·g^(−1);65.26%).Besides,the presence of oxygen vacancies can also promote the separation of electron-hole pairs.Our research demonstrates that oxygen vacancies could act as promising candidates for photocatalytic CO_(2) reduction,offering fundamental guidance for the actual photoreduction of diluted CO_(2) in the future. | Weiyi Chen Xueming Liu Bin Han Shujie Liang Hong Deng Zhang Lin | 2021 | Nano Research2021，14，3： | 2 |

| 6 | Ultracompact fiber laser based on a highly integrated optical device显示文摘The ultrafast fiber laser has attracted a great deal of research interest due to its low cost, high efficiency, and simple maintenance. Optical passive devices are vital parts of a fiber laser. In order to obtain a fiber laser with high quality, optical passive devices with high performance are required. Here, we demonstrate a highly integrated optical device with the combination of a saturable absorber(SA), coupler, isolator, wavelength division multiplexer, and erbium-doped fiber. The built-in SA has a modulation depth of 7% and can withstand high pump power due to the unique structure of the proposed device. The proposed device is applied to an ultracompact fiber laser, which greatly simplifies the laser structure and reduces the size of the proposed laser. The central wavelength, pulse duration, repetition rate, and signal-to-noise ratio of the output soliton are 1560 nm, 1.06 ps,25.8 MHz, and 50 dB, respectively. The proposed device has great potential for application in high-power and high-frequency fiber lasers. The proposed ultracompact fiber laser has important applications in optical communication, optical sensing, optical frequency combs, and micromachining. | XIAOXIANG HAN XUEMING LIU | 2019 | Photonics Research2019，7，1： | 1 |
| 7 | Lattice-strained nanotubes facilitate efficient natural sunlight-driven CO_(2) photoreduction显示文摘Photocatalytic reduction of CO_(2) holds tremendous promise for alleviating the energy crisis.Despite the progress that has been,made,there are still some challenges to overcome,such as the realization under real sunlight rather than the simulation condition.In this work,ultrathin Ni_(2)(OH)(PO_(4))nanotubes(NTs)prepared through hydrothermal route are applied as a novel catalyst for photocatalytic reduction of CO_(2) under real sunlight.The prepared Ni_(2)(OH)(PO_(4))NTs exhibit a 11.3 μmol·h^(-1) CO production rate with,96.1% CO selectivity.Interestingly,Ni_(2)(OH)(PO_(4))NTs have a positive impact on the facilitation of photoreduction in diluted CO_(2).Notably,when the system is performed under real sunlight,Ni_(2)(OH)(PO_(4))NTs afford an accumulated CO of ca.26.8 nmol with,96.9% CO selectivity,exceeding most previous inorganic catalysts under simulated irradiation in the laboratory.Our experimental results demonstrate that the multisynergetic effects induced by surface-OH and the lattice strain serve as highly active sites for CO_(2) molecular adsorption and activation as well as electron transfer,hence enhancing photoreduction activity.Therefore,this work provides experimental basis that CO_(2) photocatalysis can be put into practical use. | Shujie Liang Xueming Liu Zuqi Zhong Bin Han Xiaohui Zhong Weiyi Chen Kainan Song Hong Deng Zhang Lin | 2021 | Nano Research2021，14，8： | 0 |
| 8 | DLSLA 3-D SAR imaging algorithm for off-grid targets based on pseudo-polar formatting and atomic norm minimization显示文摘This paper concerns the imaging problem for downward looking sparse linear array three-dimensional synthetic aperture radar(DLSLA 3-D SAR) under the circumstance of sparse and non-uniform cross-track dimensional virtual phase centers configuration. Since the 3-D imaging scene behaves typical sparsity in a certain domain, sparse recovery approaches hold the potential to achieve a better reconstruction performance. However,most of the existing compressive sensing(CS) algorithms assume the scatterers located on the pre-discretized grids, which is often violated by the off-grid effect. By contrast, atomic norm minimization(ANM) deals with sparse recovery problem directly on continuous space instead of discrete grids. This paper firstly analyzes the off-grid effect in DLSLA 3-D SAR sparse image reconstruction, and then introduces an imaging method applied to off-gird targets reconstruction which combines 3-D pseudo-polar formatting algorithm(pseudo-PFA) with ANM. With the proposed method, wave propagation and along-track image reconstruction are operated with pseudo-PFA, then the cross-track reconstruction is implemented with semidefinite programming(SDP) based on the ANM model. The proposed method holds the advantage of avoiding the off-grid effect and managing to locate the off-grid targets to accurate locations in different imaging scenes. The performance of the proposed method is verified and evaluated by the 3-D image reconstruction of different scenes, i.e., point targets and distributed scene. | Qian BAO Kuoye HAN Xueming PENG Wen HONG Bingchen ZHANG Weixian TAN | 2016 | Science China(Information Sciences)2016，59，6： | 0 |
| 9 | Behavioral Feature and Correlative Detection of Multiple Types of Node in the Internet of Vehicles显示文摘Undoubtedly,uncooperative or malicious nodes threaten the safety of Internet of Vehicles(IoV)by destroying routing or data.To this end,some researchers have designed some node detection mechanisms and trust calculating algorithms based on some different feature parameters of IoV such as communication,data,energy,etc.,to detect and evaluate vehicle nodes.However,it is difficult to effectively assess the trust level of a vehicle node only by message forwarding,data consistency,and energy sufficiency.In order to resolve these problems,a novel mechanism and a new trust calculating model is proposed in this paper.First,the four tuple method is adopted,to qualitatively describing various types of nodes of IoV;Second,analyzing the behavioral features and correlation of various nodes based on route forwarding rate,data forwarding rate and physical location;third,designing double layer detection feature parameters with the ability to detect uncooperative nodes and malicious nodes;fourth,establishing a node correlative detection model with a double layer structure by combining the network layer and the perception layer.Accordingly,we conducted simulation experiments to verify the accuracy and time of this detection method under different speed-rate topological conditions of IoV.The results show that comparing with methods which only considers energy or communication parameters,the method proposed in this paper has obvious advantages in the detection of uncooperative and malicious nodes of IoV;especially,with the double detection feature parameters and node correlative detection model combined,detection accuracy is effectively improved,and the calculation time of node detection is largely reduced. | Pengshou Xie Guoqiang Ma Tao Feng Yan Yan Xueming Han | 2020 | Computers, Materials & Continua2020，，8： | 0 |
