| 1 | Research progress in the SO2 resistance of the catalysts for selective catalytic reduction of NOx显示文摘The selective catalytic reduction(SCR) of NO_x with NH_3 has been proven to be an efficient technology for NO_x conversion to N_2. However, the catalysts used for SCR usually suffer from the problem of sulfur poisoning which seriously limits their practical application. This review summarized sulfur poisoning mechanisms of various SCR de NO_x catalysts and strategies to reduce deactivation caused by SO_2 such as doping metals, controlling the structures and morphologies of the catalysts, and selecting appropriate supports. The methods and procedures of catalysts preparation and the reaction conditions also have effect on SO_2-resistance of the catalysts.Several novel catalyst systems that exhibited good SO_2 resistance are also introduced. This paper could provide guidance for the development of highly efficient sulfur-tolerant de NO_x catalysts. | Minhua Zhang Baojuan Huang Haoxi Jiang Yifei Chen | 2017 | Chinese Journal of Chemical Engineering2017，25，12： | 8 |
| 2 | Local Robust Sparse Representation for Face Recognition With Single Sample per Person显示文摘The purpose of this paper is to solve the problem of robust face recognition(FR) with single sample per person(SSPP). In the scenario of FR with SSPP, we present a novel model local robust sparse representation(LRSR) to tackle the problem of query images with various intra-class variations,e.g., expressions, illuminations, and occlusion. FR with SSPP is a very difficult challenge due to lacking of information to predict the possible intra-class variation of the query images.The key idea of the proposed method is to combine a local sparse representation model and a patch-based generic variation dictionary learning model to predict the possible facial intraclass variation of the query images. The experimental results on the AR database, Extended Yale B database, CMU-PIE database and LFW database show that the proposed method is robust to intra-class variations in FR with SSPP, and outperforms the state-of-art approaches. | Jianquan Gu Haifeng Hu Haoxi Li | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，2： | 4 |
| 3 | Stability and Antioxidant Activity of Anthocyanins from Flowers of Rhododendron pulchrum Sweet.显示文摘The effects of light,temperature,p H,oxidant and reducing agents,metal ions and food additives on the stability of anthocyanins from flowers of Rhododendron pulchrum Sweet.,as well as their scavenging capacity for ·OH,O^(2-)· and DPPH· free radicals and reducing power were investigated. The results showed that the anthocyanins from flowers of R. pulchrum were relatively stable in the room with natural light,at temperature lower than 45℃,and in the solution with p H ≤ 4. The addition of Na^+,K^+Ca^(2 +)metal ions,glucose,sodium benzoate,acetic acid and salt had little effect,but Cu^(2 +),Zn^(2 +),Fe^(3 +),Al^(3 +),starch and sodium glutamate showed adverse effects on the stability of the anthocyanins. The anthocyanins from flowers of R. pulchrum had a good antioxidant effect,and their scavenging capacity for · OH,O^(2-)·,DPPH· was better than that of the same concentration of Vc. | Mei ZHANG Benyong LOU Yanjie ZHANG Haoxi FU | 2018 | Asian Agricultural Research2018，10，10： | 2 |
| 4 | The contribution of photoinduced charge-transfer enhancement to the SERS of uranyl(Ⅵ) in a uranyl-Ag_2O complex显示文摘Charge-transfer(CT) is an important enhancement mechanism in the field of surface-enhanced Raman scattering(SERS) that typically increases the Raman intensity of molecules by as much as 10–100 times.Herein, a low-cost Ag_2O aggregates substrate was prepared via a facile chemical precipitation method,and the calculated CT-based enhancement factor of the uranyl ions adsorbed on it reached as high as 10~5, a metal-comparable value. The efficient photoinduced CT process from the valence band of Ag_2O to the LUMO of uranyl ions under appropriate excitation sources resulted in the repulsion of the axial oxygen atoms of the O=U=O bond, which enhanced its polarizability, creating a more intense Raman mode. To the best of our knowledge, this study firstly reports such a strong photoinduced CT enhancement of uranyl ions, with concentrations of 10^(-8) mol L^(-1) or lower being detected using this Ag_2O substrate. Most importantly, this research has shown that the photoinduced CT enhancement also contributes to the SERS of uranyl ions on pure Ag substrates which have often been ascribed to the electromagnetic enhancement in previous studies. In addition, Ag_2O can be used to selectively detect uranyl ions without interference from many other molecules or ions because of the energy matching rule of the photoinduced CT process, which was readily available for uranyl detection in the environmental aqueous solution. | Shaofei Wang Shanli Yang Haoxi Wu Jiaolai Jiang Lang Shao Yiming Ren Yingru Li Chuanhui Liang Mingfu Chu Xiaolin Wang | 2019 | Science Bulletin2019，64，5： | 1 |

| 7 | Static magnetic field analysis of hollow-cup motor model and bow-shaped permanent magnet design显示文摘The hollow-cup Permanent Magnet(PM) motors have the characteristics of low power consumption, and are widely used in the aerospace field. At present, the tile-shaped PMs used by hollow-cup PM motors have poor sinusoidal characteristics of the air gap magnetic flux density waveform, which will cause torque ripple. The existing method for improving the air gap magnetic flux density waveform is not very effective when applied to hollow cup, a special motor with no stator core and large air gap. A bow-shaped PMs structure is designed for the hollow-cup motor in this paper. First, the equivalent surface current method is used to calculate the analytical formula of the static magnetic field of the model. Then, the Finite Element(FE) method is used to calculate the static air gap flux density waveform of conventional tile-shaped PMs and bow-shaped PMs with different bow heights, and the corresponding harmonics and sine distortion are obtained by Fourier decomposition. The simulation results show that the bow-shaped PMs can effectively improve the sinusoidal characteristics of the static air gap flux density waveform. And the suitable bow height is determined. Finally, a prototype is made based on the suitable bow height for experiments, and compared with the analytical result and the FE result, and the accuracy and effectiveness of the bow-shaped PMs with the suitable bow height are verified. | Jinji SUN Gen XING Xinxiu ZHOU Haoxi SUN | 2022 | Chinese Journal of Aeronautics2022，35，9： | 1 |

| 14 | Reviews on sulphur corrosion phenomenon of the oil-paper insulating system in mineral oil transformer显示文摘The active sulphur compounds in transformer oil would react with copper wires and produce cuprous sulphides,which then attach themselves to the surface of copper wires and insulating paper,thus reducing the electrical performance of oil-paper insulation and causing insulation failure.This article aims to make a comprehensive summary on the field of sulphur corrosion of oil-paper insulation in the mineral oil transformer,including the corrosion mechanism of sulphide on copper sheets,the deterioration mechanism of sul-phide on oil-paper,the factors influencing sulphur corrosion reaction,the method of characterising the degree of sulphur corrosion,the protection technology of sulphur corrosion and the field operation measures for sulphur corrosion.Moreover,four key problems that need to be further solved were sorted out:the synergistic deterioration mechanism of sulphide and its transformation mechanism,the micro-process and forming path of sulphur corrosion reaction,the characteristic parameters and quantitative charac-terisation methods of sulphur corrosion degree,and the effective protection technology of sulphide corrosion.To solve these problems,efforts will be made for deeper understanding of the sulphur corrosion phenomenon and its deterioration mechanism based on theo-retical background,the assessment methods and protection technology,endeavouring to put forward solid theoretical basis and feasible technical means for preventing sulphur corrosion insulation failure. | Haoxi Cong Hao Pan Danyang Qian Haiyu Zhao Qingmin Li | 2021 | High Voltage2021，6，2： | 1 |
| 15 | Micro‐mechanism study on synergistic degradation of the oil‐paper insulation with dibenzyl disulfide,hexadecyl mercaptan and benzothiophene显示文摘In recent years,there have been many cases of transformer failures caused by corrosive sulfides.At present,research mainly focuses on the single sulfide dibenzyl disulphide,but few research on multiple sulphur or the oil‐paper hybrid insulation.In this study,three typical sulfides dibenzyl disulfide,hexadecyl mercaptan and benzothiophene were selected to form seven sulfide‐oil‐paper models.Then relaxation calculations were carried out,and through molecular dynamics simulation,the synergistic effect of different sulfides on the properties of insulating paper and insulating oil was discussed.Results show that the coexistence of the three sulfides has the most severe weakening on the mechanical properties of cellulose,and it also causes great damage to hydrogen bonds.Hexadecyl mercaptan has a weaker effect on hydrogen bond destruction,but it will greatly aggravate the cellulose chain movement.The viscosity of insulating oil is generally increased by the influence of sulfide.Hexadecyl mercaptan is the main factor affecting the viscosity.Thiophene has little effect on the viscosity,ctive protection technology on sulphur corrosion. | Haoxi Cong Hao Pan Xuefeng Hu Minhao Zhang Qingmin Li | 2021 | High Voltage2021，6，3： | 0 |
| 16 | Strong metal–support interaction boosts the electrocatalytic hydrogen evolution capability of Ru nanoparticles supported on titanium nitride显示文摘Ruthenium(Ru)has been regarded as one of the most promising alternatives to substitute Pt for catalyzing alkaline hydrogen evolution reaction(HER),owing to its inherent high activity and being the cheapest platinum-group metal.Herein,based on the idea of strong metal–support interaction(SMSI)regulation,Ru/TiN catalysts with different degrees of TiN overlayer over Ru nanoparticles were fabricated,which were applied to the alkaline electrolytic water.Characterizations reveal that the TiN overlayer would gradually encapsulate the Ru nanoparticles and induce more electron transfer from Ru nanoparticles to TiN support by the Ru–N–Ti bond as the SMSI degree increased.Further study shows that the exposed Ru–TiN interfaces greatly promote the H_(2) desorption capacity.Thus,the Ru/TiN-300 with a moderate SMSI degree exhibits excellent HER performance,with an overpotential of 38 mV at 10 mA cm^(−2).Also,due to the encapsulation role of TiN overlayer on Ru nanoparticles,it displays super long-term stability with a very slight potential change after 24 h.This study provides a deep insight into the influence of the SMSI effect between Ru and TiN on HER and offers a novel approach for preparing efficient and stable HER electrocatalysts through SMSI engineering. | Xin Wang Xiaoli Yang Guangxian Pei Jifa Yang Junzhe Liu Fengwang Zhao Fayi Jin Wei Jiang Haoxi Ben Lixue Zhang | 2024 | Carbon Energy2024，6，1： | 0 |
| 17 | Development of smart wearable sensors for life healthcare显示文摘Wearable biosensors are gaining tremendous interest in the clinical and biological medical fields for their potential in providing patients with real-time diagnostic tools and time-sensitive information,non-invasive measurements of biochemical markers distributed in body fluids throughout the body.These sensors replace part of the equipment that can only be installed in hospitals and become a new choice for assessing human health.Herein,critical perspectives are put forward regarding wearable sensors in the future digital health monitoring industry.Moreover,the materials and processing technologies involved have also been discussed in recent years,along with their monitoring schemes and system-level integration technologies.Finally,the probability of wearable sensors being used in early disease detection is considerable.Thus,despite potential challenges,it is still quite promising for wearable sensors to come into production. | Haoxi Luo Bingbing Gao | 2021 | Engineered Regeneration2021，2，1： | 0 |
| 18 | Preparation of Kenaf Biochar and Its Adsorption Properties for Methylene Blue显示文摘The toxic dyestuff's from printing and dyeing wastewater have caused serious damages to the ecological environ-ment,thus exploring effective methods to remove them having become a key topic.Here,a series of biochar sam-ples were synthesized form kenaf to adsorb methylene blue(MB),which was acted as the dye representative for the test of adsorption capacity due to the presence of abundant double bond and aroma tic heterocyclic ring.By tuning the raw materials and pyrolysis temperature,a super adsorption capacity about 164.21 mg·g^(-1) was obtained over the biochar that pyrolyzed at 700℃ with the kenaf fiber as raw material Through the physical adsorption,elemental analysis,FTIR spectra and NH_(3)-TPD,it was found the high surface area and pore volume of biochar played a key role in the adsorption of MB,and the acidic sites would also assist the adsorption process.Besides,the adsorption kinetic model was ftted and calculated,implying the MB physically adsorbed on the bio-char rapidly and then occurred chemical adsorption on the acidic sites.In addition,through KBC700 recycling experiments,it was found that kenaf biochar had a good binding force to MB,which effectively avoided secondary pollution.This work provides important insights for the adsorption mechanism of MB by biochar,also offers some guidance for the further synthesis of biochar from various biomass. | Xin Wan Zhigang Xia Xiaoli Yang Chenfeng Zhou Yuanming Zhang Haoxi Ben Guangting Han Wei Jiang | 2022 | Journal of Renewable Materials2022，10，12： | 0 |
