| 2 | Multifunctional superhydrophobic coatings fabricated from basalt scales on a fluorocarbon coating base显示文摘Superhydrophobic coatings are increasingly being evaluated as anticorrosion interventions in exceedingly hydrated environments.However,concerns about their long-term durability and amenability to large-area applications in marine environments are still hindering commercial-scale deployment.This study is focused on development of easy-to-apply superhydrophobic coatings,with multifunctional capabilities,in order to extend the integrity and durability of the coatings in harsh marine environments.Here,a set of facile methods involving selective chemical etching using concentrated Na OH,as well as fluorination with perfluoropolyether methyl ester were adopted to fabricate a superhydrophobic surface on basalt scales,having the required rough hierarchical micro-nanotextured and low surface energy.The superhydrophobic basalt scales were subsequently aligned atop a fluorocarbon resin,pre-deposited on a metal substrate,to yield a multifunctional superhydrophobic coating(3μL water droplet;contact angle=165.1°,rolling angle=0.7°),easily amenable to large surface area application and having excellent wear resistance,UV-aging resistance,salt spray resistance,corrosion resistance and antibacterial capabilities. | Hongpeng Zheng Li Liu Fandi Meng Yu Cui Zhong Li Emeka E.Oguzie Fuhui Wang | 2021 | Journal of Materials Science & Technology2021,,25: | 8 |
| 3 | Structural Surface Crack Monitoring Method Based on Electrical Potential Technique and Modern Surface Technology显示文摘Crack monitoring plays a great role in modern structural health monitoring, however, most of the conventional crack inspections have disadvantages in terms of the accuracy, expense, reliability, durability and level of instrumentation required. Thus, development of a simple and reliable crack inspection technique that allows continuous monitoring has been desired. In this paper, electrical potential technique and modern surface technology are employed together to develop a new structural surface crack monitoring method. A special crack monitoring coating sensor based on electrical potential technique was deposited on the hot spot of the structure by modern surface technology. The sensor consists of three layers: the isolated layer, the sensing layer and the protective layer. The isolated layer is prepared by anodic oxidation technology, the sensing layer is made of ion plated copper, and the protective layer is made of silicone. The thickness of each layer is at micrometer magnitude. The electrical conductivity of the sensor is very stable, and the fatigue performance of the specimen with or without coating sensor is nearly unchanged. The crack monitoring experiment result shows that there are two sudden rises of the coating sensor electrical potential values, corresponding to different stages of the crack initiation and propagation. Since the width of the surface coating sensor is only 0.5 mm, this crack monitoring sensor can detect the propagation of cracks less than 0.5 mm long. The method proposed takes the simplicity of electrical potential technique and can monitor surface crack of nearly all kinds of structures precisely. The results of this paper may form the basis of a new crack monitoring system. | CUI Ronghong HE Yuting YU Zhiming LI Hongpeng SHU Wenjun DU Jinqiang | 2011 | Chinese Journal of Mechanical Engineering2011,24,4: | 7 |

| 7 | Development of a Percentile Based Three-dimensional Model of the Buttocks in Computer System显示文摘There are diverse products related to human buttocks, which need to be designed, manufactured and evaluated with 3D buttock model. The 3D buttock model used in present research field is just simple approximate model similar to human buttocks. The 3D buttock percentile model is highly desired in the ergonomics design and evaluation for these products. So far, there is no research on the percentile sizing system of human 3D buttock model. So the purpose of this paper is to develop a new method for building three-dimensional buttock percentile model in computer system. After scanning the 3D shape of buttocks, the cloud data of 3D points is imported into the reverse engineering software(Geomagic) for the reconstructing of the buttock surface model. Five characteristic dimensions of the buttock are measured through mark-points after models being imported into engineering software CATIA. A series of space points are obtained by the intersecting of the cutting slices and 3D buttock surface model, and then are ordered based on the sequence number of the horizontal and vertical slices. The 1st, 5th, 50 th, 95 th, 99 th percentile values of the five dimensions and the spatial coordinate values of the space points are obtained, and used to reconstruct percentile buttock models. This research proposes a establishing method of percentile sizing system of buttock 3D model based on the percentile values of the ischial tuberosities diameter, the distances from margin to ischial tuberosity and the space coordinates value of coordinate points, for establishing the Nth percentile 3D buttock model and every special buttock types model. The proposed method also serves as a useful guidance for the other 3D percentile models establishment for other part in human body with characteristic points. | WANG Lijing HE Xueli LI Hongpeng | 2016 | Chinese Journal of Mechanical Engineering2016,29,3: | 2 |
| 8 | Promoting effect of chloride ions on selective oxidation of methanol to methyl formate over zirconia-supported ruthenium oxide catalysts显示文摘The effect of chloride ions on a monoclinic ZrO2-supported RuOx(RuOx/m-ZrO2) catalyst with a Ru surface density of 0.3 Ru/nm2 was studied in the selective oxidation of methanol to methyl formate(MF) at a low temperature of 373 K.The m-ZrO2 support was Cl-free,and Cl- ions were introduced into the RuOx/m-ZrO2 catalyst by impregnation with zirconium oxychloride or ammonium chloride and subsequent thermal treatment in air at 673 K.The structures of these catalysts were characterized by X-ray diffraction,Raman and X-ray photoelectron spectroscopies.Their reducibility was probed by temperature-programmed reduction in H2.The RuOx domains were present as highly dispersed RuO42- structure on m-ZrO2 with similar reducibility for the RuOx/m-ZrO2 samples irrespective of modification with or without Cl- ions.Introduction of appropriate amounts of zirconium oxychloride into RuOx/m-ZrO2 led to a remarkable increase in the methanol oxidation rate and MF selectivity,whereas introduction of ammonium chloride or zirconyl nitrate significantly inhibited the catalytic performance of RuOx/m-ZrO2.The promoting effect of Cl- ions derived from zirconium oxychloride can be tentatively attributed to their roles in facilitating the adsorption of methanol and desorption of MF product or its intermediates.This finding provides novel insights into the promoting effect of Cl ions on oxides-based catalysts for selective oxidation reactions. | Weizhen Li Hongpeng Zhang Xiaohui He Haichao Liu | 2013 | Journal of Energy Chemistry2013,22,3: | 2 |
| 9 | Pulse combination and compression in hollow-core fiber for few-cycle intense mid-infrared laser generation显示文摘The generation of high-peak-power,few-cycle mid-infrared(MIR)pulses using coherent beam combination and nonlinear pulse compression techniques simultaneously is demonstrated.The two pulses,with identical pulse energy of 2.8 mJ and pulse duration of 160 fs,are coherently combined at the input end of a krypton-filled hollow-core fiber(HCF),and then the bandwidth of the combined pulse is broadened to near an optical octave due to strong phase modulations,and the temporal width is compressed into a few-cycle regime.Finally,a 2.7 mJ,22.9 fs,20 Hz laser at 4μm can be obtained,and the pulse peak power is greatly enhanced compared with that of conventional single-channel optical parametric chirped pulse-amplification systems.Furthermore,the peak power generated from this system has the prospect of further scaling up through use of more channels of coherent combination,which can pave a way to generate higher peak power ultra-intense MIR pulses for strong-field physics. | Junyu Qian Pengfei Wang Yujie Peng Yanyan Li Beijie Shao Hongpeng Su Xinlin Lv Ding Wang Yuxin Leng Ruxin Li | 2021 | Photonics Research2021,9,4: | 2 |

| 11 | MXene-derived TiO_(2)nanosheets decorated with Ag nanoparticles for highly sensitive detection of ammonia at room temperature显示文摘Due to their large surface-to-volume ratio and low electronic noise,two-dimensional transition metal carbides(Ti_(3)C_(2)T_(x) MXene)and their derived transition metal oxides have demonstrated significant potential for use in high-precision gas sensing.However,the construction of high-sensitivity Ti_(3)C_(2)T_(x) MXene-based gas sensors operated at room temperature(RT)is still a major challenge.Herein,we demonstrate a sensitive nanocomposite prepared by uniformly anchoring silver nanoparticles(AgNPs)on Ti_(3)C_(2)T_(x) MXene-derived transition metal oxide(TiO_(2))nanosheets for high-sensitivity NH_(3) detection.AgNPs can not only serve as spacers to effectively prevent the restacking of MXene-derived TiO_(2)nanosheets and ensure an effective transmission highway for target gas molecules,but also enhance the sensitivity of the sensor through chemical and electronic sensitization.By integrating the unique merits of the individual components and the synergistic effects of the composites,the optimized Ag@TiO_(2)nanocomposite-based sensors revealed an extraordinary response value of 71.8 to 50 ppm NH_(3) at RT with a detection limit as low as 5 ppm.In addition,the Ag@TiO_(2)NH_(3) sensor also exhibits excellent selectivity and outstanding repeatability.This strategy provides an avenue for the development of MXene derivatives for advanced gas sensors. | Jie Wen Zihao Song Jiabao Ding Feihong Wang Hongpeng Li Jinyong Xu Chao Zhang | 2022 | Journal of Materials Science & Technology2022,,19: | 1 |

| 14 | Insight to the enhanced microwave absorption of porous N-doped carbon driven by ZIF-8:Competition between graphitization and porosity显示文摘Porous carbon-based materials are promised to be lightweight dielectric microwave absorbents.Deeply understanding the influence of graphitization grade and porous structure on the dielectric parameters is urgently required.Herein,utilizing the low boiling point of Zn,porous N-doped carbon was fabricated by carbonization of ZIF-8(Zn)at different temperature,and the microwave absorption performance was investigated.The porous N-doped carbon inherits the high porosity of ZIF-8 precursor.By increasing the carbonization temperature,the contents of Zn and N elements are decreased;the graphitization degree is improved;however,the specific surface area and porosity are increased first and then decreased.When the carbonization temperature is 1000°C,the porous N-doped carbon behaves enhanced microwave absorption.With an ultrathin thickness of 1.29 mm,the ideal RL reaches-50.57 dB at 16.95 GHz and the effective absorption bandwidth is 4.17 GHz.The mechanism of boosted microwave absorption is ascribed to the competition of graphitization and porosity as well as N dopants,resulting in high dielectric loss capacity and good impedance matching.The porous structure can prolong the pathways and raise the contact opportunity between microwaves and porous carbon,causing multiple scattering,interface polarization,and improved impedance matching.Besides,the N dopants can induce electron polarization and defect polarization.These results give a new insight to construct lightweight carbon-based microwave absorbents by regulating the graphitization and porosity. | You Zhou Hongpeng Wang Dan Wang Xianfeng Yang Hongna Xing Juan Feng Yan Zong Xiuhong Zhu Xinghua Li Xinliang Zheng | 2023 | International Journal of Minerals,Metallurgy and Materials2023,30,3: | 1 |

| 17 | A Novel Rolling Bearing Vibration Impulsive Signals Detection Approach Based on Dictionary Learning显示文摘The localized faults of rolling bearings can be diagnosed by its vibration impulsive signals.However,it is always a challenge to extract the impulsive feature under background noise and non-stationary conditions.This paper investigates impulsive signals detection of a single-point defect rolling bearing and presents a novel data-driven detection approach based on dictionary learning.To overcome the effects harmonic and noise components,we propose an autoregressive-minimum entropy deconvolution model to separate harmonic and deconvolve the effect of the transmission path.To address the shortcomings of conventional sparse representation under the changeable operation environment,we propose an approach that combines K-clustering with singular value decomposition(K-SVD)and split-Bregman to extract impulsive components precisely.Via experiments on synthetic signals and real run-to-failure signals,the excellent performance for different impulsive signals detection verifies the effectiveness and robustness of the proposed approach.Meanwhile,a comparison with the state-of-the-art methods is illustrated,which shows that the proposed approach can provide more accurate detected impulsive signals. | Chuan Sun Hongpeng Yin Yanxia Li Yi Chai | 2021 | IEEE/CAA Journal of Automatica Sinica2021,8,6: | 1 |
| 18 | A spike-trimer protein-based tetravalent COVID-19 vaccine elicits enhanced breadth of neutralization against SARS-CoV-2 Omicron subvariants and other variants显示文摘Multivalent vaccines combining crucial mutations from phylogenetically divergent variants could be an effective approach to defend against existing and future SARS-Co V-2 variants.In this study,we developed a tetravalent COVID-19 vaccine SCTV01E,based on the trimeric Spike protein of SARS-Co V-2 variants Alpha,Beta,Delta,and Omicron BA.1,with a squalenebased oil-in-water adjuvant SCT-VA02B.In the immunogenicity studies in na?ve BALB/c and C57BL/6J mice,SCTV01E exhibited the most favorable immunogenic characteristics to induce balanced and broad-spectrum neutralizing potencies against pre-Omicron variants(D614G,Alpha,Beta,and Delta)and newly emerging Omicron subvariants(BA.1,BA.1.1,BA.2,BA.3,and BA.4/5).Booster studies in C57BL/6J mice previously immunized with D614G monovalent vaccine demonstrated superior neutralizing capacities of SCTV01E against Omicron subvariants,compared with the D614G booster regimen.Furthermore,SCTV01E vaccination elicited na?ve and central memory T cell responses to SARS-Co V-2 ancestral strain and Omicron spike peptides.Together,our comprehensive immunogenicity evaluation results indicate that SCTV01E could become an important COVID-19 vaccine platform to combat surging infections caused by the highly immune evasive BA.4/5 variants.SCTV01E is currently being studied in a head-to-head immunogenicity comparison phase 3 clinical study with inactivated and m RNA vaccines(NCT05323461). | Rui Wang Hongpeng Huang Chulin Yu Chunyun Sun Juan Ma Desheng Kong Yalong Lin Dandan Zhao Shaozheng Zhou Jianbo Lu Sai Cao Yanjing Zhang Chunxia Luo Xuefeng Li Yang Wang Liangzhi Xie | 2023 | Science China(Life Sciences)2023,66,8: | 1 |
| 19 | Error aware multiple vertical planes based visual localization for mobile robots in urban environments显示文摘A novel error-aware visual localization method is proposed that utilizes vertical planes,such as vertical building facades in urban areas as landmarks.Vertical planes,reconstructed from coplanar vertical lines,are robust high-level features if compared with point features or line features.Firstly,the error models of vertical lines and vertical planes are built,where maximum likelihood estimation(MLE)is employed to estimate all vertical planes from coplanar vertical lines.Then,the closed-form representation of camera location error variance is derived.Finally,the minimum variance camera pose estimation is formulated into a convex optimization problem,and the weight for each vertical plane is obtained by solving this well-studied problem.Experiments are carried out and the results show that the proposed localization method has an accuracy of about 2 meters,at par with commercial GPS operating in open environments. | LI HaiFeng WANG HongPeng LIU JingTai | 2015 | Science China(Information Sciences)2015,58,3: | 1 |
| 20 | Maintenance of cooperation in a public goods game:A new decision-making criterion with incomplete information显示文摘Hardin's 'The Tragedy of the Commons' prophesies the inescapable collapse of many human enterprises.The emergence and abundance of cooperation in animal and human societies is a challenging puzzle to evolutionary theory.In this work,we introduce a new decision-making criterion into a voluntary public goods game with incomplete information and choose successful strategies according to previous payoffs for a certain strategy as well as the risk-averse benefit.We find that the interest rate of the common pool and the magnitude of memory have crucial effects on the average welfare of the population.The appropriate sense of individuals' innovation also substantially influences the equilibrium strategies distribution in the long run. | LI MuHan SONG HongPeng ZHANG Li ZHANG LianZhong | 2012 | Chinese Science Bulletin2012,57,6: | 1 |
