| 1 | Nitrogen-doped Co_(3)O_(4) nanowires enable high-efficiency electrochemical oxidation of 5-hydroxymethylfurfural显示文摘Developing highly efficient and cost-effective catalysts for electrochemically oxidizing biomass-derived 5-hydroxymethylfurfural(HMF)into value-added 2,5-furandicarboxylic acid(FDCA)is of great importance.Herein,we report a controllable nitrogen doping strategy to significantly improve the catalytic activity of Co_(3)O_(4)nanowires for highly selective electro-oxidation of HMF into FDCA.The nitrogen doping leads to the generation of defects including nitrogen dopants and oxygen vacancies in Co_(3)O_(4)nanowires,which is conducive to the formation of catalytically active sites.As a result,the electro-oxidation potential for HMF is only 1.38 V(vs.RHE)when the current density reaches 50 mA/cm^(2).More importantly,the conversion rate of HMF is as high as 99.5%,and the yield of FDCA is up to 96.4%. | Mengxiao Sun Yue Wang Chunsen Sun Yan Qi Jia Cheng Yumei Song Lixue Zhang | 2022 | Chinese Chemical Letters2022，33，1： | 2 |
| 2 | Research Status, Critical Technologies, and Development Trends of Hydraulic Pressure Pulsation Attenuator显示文摘Hydraulic pumps are a positive displacement pump whose working principle causes inherent output flow pulsation.Flow pulsation produces pressure pulsation when encountering liquid resistance.Pressure pulsation spreads in the pipeline and causes vibration,noise,damage,and even pipeline rupture and major safety accidents.With the development of airborne hydraulic systems with high pressure,power,and flow rate,the hazards of vibration and noise caused by pressure pulsation are also amplified,severely restricting the application and development of hydraulic systems.In this review paper,the mechanism,harm,and suppression method of pressure pulsation in hydraulic systems are analyzed.Then,the classification and characteristics of pulsation attenuators according to different working principles are described.Furthermore,the critical technology of simulation design,matching method with airborne piston pumps,and preliminary design method of pulsation attenuators are proposed.Finally,the development trend of pulsation attenuators is prospected.This paper provides a reference for the research and application of pressure pulsation attenuators. | Yan Wang Tongsheng Shen Chunsen Tan Jian Fu Shengrong Guo | 2021 | Chinese Journal of Mechanical Engineering2021，34，1： | 2 |
| 3 | Association schemes of quadratic forms over a finite field of characteristic two显示文摘For the association schemes of quadratic forms over a finite field of characteristic two, the parameters of this association scheme are discussed by using matrix skill. For n=2, 3 , all the parameters are computed. For n≥3 , the formulas of parameters P * 2 -2j+1 and related recursion formulas of the general parameters P * ** are obtained. | Yangxian Wang Chunsen Wang Changli Ma | 1998 | Chinese Science Bulletin1998，43，23： | 1 |
