3A novel linear microprobe array for the fabrication of neural microelectrodes显示文摘A novel linear microprobe array(LMPA)has been developed by a conventional microfabrication method from silicon.The LMPA leverages the properties of conventional microwire with additional features of naturally formed regular spacing.With the help of periodic microprobe arrays and double-side V-grooves fabricated in advance between each pair of the two microprobes’rear ends,the number of microprobe units for assembly in one array can be flexibly chosen by cleavage fracture from the LMPA.The fabrication method was demonstrated and the prototype device was assessed by electrochemical impedance spectroscopy(EIS)and in vivo test.The SNR of the spikes recorded was 6.ZHAO Shan Shan PEI Wei Hua ZHAO Hui WANG Yi Jun CHEN San Yuan CHEN Yuan Fang ZHANG He GUO Dong Mei GUI Qiang CHEN Hong Da 2015Science China(Technological Sciences)2015,58,2:3
4Comparative study of MCe_(0.75)Zr_(0.25)O_(y)(M=Cu,Mn,Fe)catalysts for selective reduction of NO by CO:Activity and reaction pathways显示文摘Basic oxygen furnace steelmaking leads to the production of CO-rich off-gas.When CO and NO are combined in off-gas,selective catalytic reduction by CO(CO-SCR)effectively achieves the synergistic removal of both pollutants.In this paper,CuCe_(0.75)Zr_(0.25)O_(y),MnCe_(0.75)Zr_(0.25)O_(y),and FeCe_(0.75)Zr_(0.25)O_(y) catalysts are prepared and evaluated for their CO-SCR activity,and the results show that the reaction system needs to be anaerobic;thus,the CO-SCR reaction can be dominant.The T_(90) values of CuCe_(0.75)Zr_(0.25)O_(y) and FeCe_(0.75)Zr_(0.25)O_(y) are 200℃ and 223℃,respectively.The activities of these two catalysts are higher than that of MnCe_(0.75)Zr_(0.25)O_(y)(T_(90)=375℃).Linear nitrate and bridged bidentate nitrate are the main intermediate species involved in NO conversion on the catalyst surface,and bidentate CO_(3)^(2-)��coordination is the main intermediate species involved in CO conversion on the catalyst surface.CuCe_(0.75)Zr_(0.25)O_(y) has high lattice oxygen mobility and is more likely to react with NO and CO.In the presence of oxygen,most CO is oxidized by O_(2),which increases continuously to 100%,100%,and 98%for CuCe_(0.75)Zr_(0.25)O_(y),FeCe_(0.75)Zr_(0.25)O_(y),and MnCe_(0.75)Zr_(0.25)O_(y),respectively;additionally,CO is oxidized by O_(2),and the CO-SCR reaction cannot be carried out.Junyao He Running Kang Xiaolin Wei Junqin Huang Feng Bin Kwun Nam Hui Kwan San Hui Dongyin Wu 2021Carbon Resources Conversion2021,4,1:2
5Electrode/electrolyte interface and interface reactions of solid oxide cells:Recent development and advances显示文摘High temperature solid oxide cells(SOCs)consisted of solid oxide fuel cells(SOFCs)and solid oxide electrolysis cells(SOECs)are considered one of the most environmentally friendly and efficient energy conversion technology to store renewal energy from sun and wind in hydrogen and generate electricity from the fuels such as hydrogen and natural gas with high efficiency and very low greenhouse gas emission.Over the last few decades,the development of SOC technologies in particularly SOFCs has experienced significant progress and much of the recent research have paid great efforts in understanding the processes occurring at the electrode/electrolyte interfaces.As electrochemical reactions mainly proceed at the gas,electrode and electrolyte three phase boundaries(TPBs),the microstructure and properties of the electrode/electrolyte interfaces thus play a crucial role in determining the overall cell performance and durability.Herein,we review the progress and achievements in the fundamental researches of the electrode/electrolyte(mainly oxygen-conducting)interface evolution behavior under open circuit and polarization conditions.Studies involving interfacial phenomena such as interface formation and reactions,element segregation and diffusion,micropore formation and delamination are summarized and discussed in detail.Besides,the state of the art characterization techniques that have been employed to examine the interface behavior are reviewed.Finally,the challenges and prospects of the interface research in the improvement of the performance and durability of a SOC device are discussed.Shuai He San Ping Jiang 2021Progress in Natural Science:Materials International2021,31,3:2

14A critical review of key materials and issues in solid oxide cells显示文摘Solid oxide cells(SOCs)are all solid ceramic devices with the dual functionality of solid oxide fuel cells(SOFCs)to convert the chemical energy of fuels like H2,natural gas and other hydrocarbons to electricity and of solid oxide electrolysis cells(SOECs)to store renewable electric energy of sun and wind in hydrogen fuel.Among the electrochemical energy conversion and storage devices,SOCs are the most clean and efficient technology with unique dual functionality.Due to the high operation temperature(typically 600–800°C),SOCs exhibit many advantages over other energy conversion devices,such as low material cost,high efficiency and fuel flexibility.There has been rapid development of SOC technologies over the last decade with significant advantages and progress in key materials and a fundamental understanding of key issues such as an electrode,electrolyte,performance degradation,poisoning,and stack design.The reversible polarization also has a critical effect on the surface segregation and stability of the electrode and electrode/electrolyte interface.This critical review starts with a brief introduction,working principles and thermodynamics of SOC technology to readers with interests in this rapidly developing and emerging field.Then the key materials currently used in SOCs are summarized,followed by the discussion of the most advanced electrode modification methods and critical issues of SOCs,including the surface chemistry,segregation,electrode/electrolyte interface and varying material degradation mechanisms under reversible operations.The challenges and prospects of SOC technology for future developments are discussed.Shuai He Yuanfeng Zou Kongfa Chen San P.Jiang 2023Interdisciplinary Materials2023,2,1:1

17Ochronotic arthropathy of bilateral hip joints:A case report显示文摘BACKGROUND Ochronosis,also known as alkaptonuria,is a rare autosomal recessive selfmetabolic disease arising from deficiency of homogentisate 1,2 dioxygenase enzyme.It affects several organs and muscoskeletal structures.We herein report a case of a patient who presented with severe hip arthropathy complicated with late stage ochronosis.CASE SUMMARY A 56-year-old male patient was admitted in our department in 2019 with complaints of chronic low backache and left hip pain.After the required investigations were done,lumbar disc herniation and severe hip arthritis were the initial diagnosis.A total left hip arthroplasty was performed.Ochronotic osteoarthritis was only obtained post-surgery as confirmatory diagnosis.He was again admitted mid 2022 with the same complaints on the right hip.Subsequently,he underwent a total right hip arthroplasty.Post-operative recovery and follow-ups were deemed very satisfactory.CONCLUSION Ochronosis is an unusual diagnosis for a patient who presents with typical hip arthritis.Thus,unless meticulous history taking and advanced laboratory tests,the diagnosis can easily be missed by surgeons.Nicolas Yap San Min Urba Rafi Juan Wang Bin He Lei Fan 2023World Journal of Clinical Cases2023,11,1:0

19Risk assessment of oil and gas pipelines hot work based on AHP-FCE显示文摘A new quantitative risk assessment method for hot work is proposed based on the analytic hierarchy process(AHP)and fuzzy comprehensive evaluation(FCE).It can help pipeline companies realize the risk management of hot work and further ensure the safe operation of oil and gas pipelines.Taking one natural gas pipeline in China as an example,this paper evaluates the risk of a single hot work in the spring of one natural gas pipeline in a high consequence region.First of all,the risk factors are determined with reference to the job safety analysis(JSA),and then experts were invited to fill out a questionnaire to collect their opinions.According to the results of the questionnaire,AHP is used to calculate the weight coefficients of the evaluation indicators,and FCE is used to evaluate the risk level of hot work.After calculation,the comprehensive risk score of hot work is 40.888.It belongs to a'general risk'.This method can not only quantitatively evaluate the risk levels of hot work,but also reasonably sort the importance of various risk factors.It is helpful for the effective management of hot work and provides suggestions for implementing control measures.San He Huilan Xu Jianxiong Zhang Peiqiang Xue 2023Petroleum2023,9,1:0
20A neutron diffraction investigation of high valent doped barium ferrite with wideband tunable microwave absorption显示文摘The barium ferrite BaTi_(x)Fe_(12−x)O_(19)(x=0.2,0.4,0.6,0.8)(BFTO-x)ceramics doped by Ti4+were synthesized by a modified sol–gel method.The crystal structure and magnetic structure of the samples were determined by neutron diffraction,and confirm that the BFTO-x ceramics were high quality single phase with sheet microstructure.With x increasing from 0.2 to 0.8,the saturation magnetization(M_(s))decreases gradually but the change trend of coercivity(H_(c))is complex under the synergy of the changed grain size and the magnetic crystal anisotropy field.Relying on the high valence of Ti^(4+),double resonance peaks are obtained in the curves of the imaginary part of magnetic conductivity(μ′′)and the resonance peaks could move toward the low frequency with the increase of x,which facilitate the samples perform an excellent wideband modulation microwave absorption property.In the x=0.2 sample,the maximum reflection loss(RL)can reach−44.9 dB at the thickness of only 1.8 mm,and the bandwidth could reach 5.28 GHz at 2 mm when RL is less than−10 dB.All the BFTO-x ceramics show excellent frequency modulation ability varying from 18(x=0.8)to 4 GHz(x=0.4),which covers 81%of the investigated frequency in microwave absorption field.This work not only implements the tunable of electromagnetic parameters but also broadens the application of high-performance microwave absorption devices.Jun LI Yang HONG San HE Weike LI Han BAI Yuanhua XIA Guangai SUN Zhongxiang ZHOU 2022Journal of Advanced Ceramics2022,11,2:0
