| 1 | Development and experimental validation of an automatic parking brake system with less driveline sensor显示文摘Electrical Parking Brake(EPB) has been popularly used in passenger cars over the past ten years. With the help of the several kinds of sensors mounted in driveline for the total traction force estimation, EPB can obtain well performance on drive-off assistance and automatic parking brake. Furthermore, its AUTOHOLD function can realize automatic parking brake and ease the driver. However, given that the higher cost and complexity of this traction force estimation method based on the driveline sensors and its slower response resulted by applying maximum parking force for safety parking while driving off, a novel automatic parking brake system without these transmission system sensors, such as clutch position sensor for the cars with manual transmission, is proposed in this paper, including its control scheme and application test. Firstly, the indirect judgement method of the appropriate moment to release the parking brake, which is based on the car pitch moment when it drives off, is introduced according to the force analysis when the car is ready to go. Then a pragmatic mass estimation method for proper brake force calculation is proposed for improving the drive-off performance. In addition, for the convenience and drivability of skillful driver, as well as the system reliability, a mechanical redundant design to reserve the conventional handbrake lever is also described. Finally, various simulations based on CarSim software and road tests are performed to validate its effectiveness. | WANG JunNian SUN NaNa YAN JiaWei SONG DaFeng WANG QingNian | 2018 | Science China(Technological Sciences)2018，61，11： | 4 |
| 2 | Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety. | Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 4 |
| 3 | Revisiting lithium-storage mechanisms of molybdenum disulfide显示文摘Molybdenum disulfide(MoS_(2)),a typical two-dimensional transition metallic layered material,attracts tremendous attentions in the electrochemical energy storage due to its excellent physicochemical properties.However,with the deepening of the research and exploration of the lithium storage mechanism of these advanced MoS_(2)-based anode materials,the complex reaction process influenced by internal and external factors hinders the exhaustive understanding of the lithium storage process.To design stable anode material with high performance,it is urgent to review the mechanisms of reported anode materials and summarize the related factors that influence the reaction processes.This review aims to dissect all possible side reactions during charging and discharging process,uncover internal and external factors inducing various anode reactions and finally put forward strategies of controlling high cycling capacity and super-stable lithium storage capability of MoS_(2).This review will be helpful to the design of MoS_(2)-based lithium-ion batteries(LIBs) with excellent cycle performance to enlarge the application fields of these advanced electrochemical energy storage devices. | Chun Sun Mingming Liu Longlu Wang Lingbin Xie Weiwei Zhao Jianmin Li Shujuan Liu Dafeng Yan Qiang Zhao | 2022 | Chinese Chemical Letters2022，33，4： | 3 |
| 4 | Engineering Cu_(1.96)S/Co_(9)S_(8) with sulfur vacancy and heterostructure as an efficient bifunctional electrocatalyst for water splitting显示文摘Defect and interface engineering have been recognized as efficient strategies for developing high-performance electrocatalysts.However,it is still challenging to couple defect and interface engineering in transition metal sulfides and understand their dynamic evolution process during electrocatalysis.Herein,we developed one-step pyrolysis of bimetallic sulfide to construct S vacancy-rich Cu_(1.96)S/Co_(9)S_(8) heterostructure by controlling the critical decomposition temperature.The as-synthesized Cu_(1.96)S/Co_(9)S_(8) exhibits excellent bifunctional electrocatalytic performance,with a low overpotential of 99 and 200 mV at 10 mA cm−2 towards hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)in 1.0 mol/L KOH electrolyte,respectively.A symmetric two-electrode cell with Cu_(1.96)S/Co_(9)S_(8) delivered a current density of 10 mA cm^(−2) at a low voltage of 1.43 V and showed long-term stability for 200 h.A series of in/ex-situ techniques revealed that the electrochemical reconfiguration only appeared in the OER process,resulting in the CoOOH/CuO and SO42−species promoting OER performance.Meanwhile,the S vacancy and heterostructure interface in Cu_(1.96)S/Co_(9)S_(8) were proved to optimize the electronic structure and the adsorption of intermediates for HER by density function theory(DFT)simulations.This work provides a promising strategy to construct metal sulfides with rich defects and heterogeneous interfaces and understand their dynamic evolution process for electrochemical storage and conversion devices. | Yuanhua Xiao Ya Shen Dangcheng Su Shiwei Zhang Jinlin Yang Dafeng Yan Shaoming Fang Xuezhao Wang | 2023 | Journal of Materials Science & Technology2023，，23： | 1 |
| 5 | First-principles study of methanol adsorption on heteroatom-doped phosphorene显示文摘First-principles calculations based on van der Waals(vdW) corrected density functional theory(DFT) are firstly employed to investigate the adsorption of methanol(CH_3OH) gas molecule on pristine and Xdoped phosphorene( =B, C, N and O). The CH_3OH gas molecule is placed on the top of different phosphorene surfaces, the whole adsorption systems are fully optimized by using Vienna ab initio simulation package(VASP). The calculation results demonstrate that both pristine and heteroatomdoped phosphorene are sensitive to CH_3OH gas molecule with a moderate adsorption energy and an excellent charge transfer. Among all the investigated adsorption configurations, CH_3OH gas molecule is physically absorbed on pristine phosphorene and heteroatom-doped phosphorene. The N and O doping improve the adsorption of phosphorene with CH_3OH gas molecule, while B and C doping are almost not beneficial compared to the pristine phosphorene. The results suggest that N-doped and O-doped phosphorene are ideal candidates used for CH_3OH gas sensing. | Dongdong Liu Yongliang Shi Li Tao Dafeng Yan Ru Chen Shuangyin Wang | 2019 | Chinese Chemical Letters2019，30，1： | 1 |
