| 1 | Fine particulate matter(PM_(2.5)/PM_(1.0)) in Beijing,China: Variations and chemical compositions as well as sources显示文摘Particulate matter(i.e.,PM_(1.0) and PM_(2.5)),considered as the key atmospheric pollutants,exerts negative effects on visibility,global climate,and human health by associated chemical compositions.However,our understanding of PM and its chemical compositions in Beijing under the current atmospheric environment is still not complete after witnessing marked alleviation during 2013–2017.Continuous measurements can be crucial for further air quality improvement by better characterizing PM pollution and chemical compositions in Beijing.Here,we conducted simultaneous measurements on PM in Beijing during 2018–2019.Results indicate that annualmean PM_(1.0) and PM_(2.5) concentrations were 35.49±18.61μg/m^(3) and 66.58±60.17μg/m^(3),showing a positive response to emission controls.The contribution of sulfate,nitrate,and ammonium(SNA)played an enhanced role with elevated PM loading and acted as the main contributors to pollution episodes.Discrepancies observed among chemical species between PM_(1.0) and PM_(2.5) in spring suggest that sand particles trend to accumulate in the range of 1–2.5μm.Pollution episodes occurred accompanied with southerly clusters and high formation of SNA by heterogeneous reactions in summer and winter,respectively.Results from positive matrix factorization(PMF)combined with potential source contribution function(PSCF)models showed that potential areas were seasonal dependent,secondary and vehicular sources became much more important compared with previous studies in Beijing.Our study presented a continuous investigation on PM and sources origins in Beijing,which provides a better understanding for further emission control as well as a reference for other cities in developing countries. | Lining Luo Xiaoxuan Bai Shuhan Liu Bobo Wu Wei Liu Yunqian Lv Zhihui Guo Shumin Lin Shuang Zhao Yan Hao Jiming Hao Kai Zhang Aihua Zheng Hezhong Tian | 2022 | Journal of Environmental Sciences2022,34,11: | 3 |
| 2 | A Novel Electric Dual Motor Transmission for Heavy Commercial Vehicles显示文摘As a vital vehicle part,the powertrain system is undergoing a fast transition towards electrification.The new integrated electric drive system has been widely used,especially for passenger cars.In this work,a novel electric dual motor transmission is proposed for heavy commercial vehicles.The transmission scheme is firstly introduced,which can achieve 9 different operating modes including 5 single motor modes and 4 dual motor modes.Then,the mode shift map with minimum energy consumption is designed based on the motor efficiency map and the proposed energy management strategy.The driving power is appropriately distributed between the two motors in dual motor modes under the condition of minimum power consumption.In addition,a coordinated control strategy is developed for mode shift control without power interruption.The results show that the electric dual motor transmission has advantages in power consumption and power shift ability compared with the conventional single motor automated manual transmission. | Xiangyang Xu Jiajia Liang Qingjun Hao Peng Dong Shuhan Wang Wei Guo Yanfang Liu Zhonghua Lu Jiantao Geng Bin Yan | 2021 | Automotive Innovation2021,4,1: | 2 |
| 3 | Supramolecular Prodrug Micelles Constructed by Drug-Drug Conjugate with Water Soluble Pillar[6]arene for Controllable and Rapid Drug Release显示文摘The first attempt of constructing supramolecular prodrug micelles based on the host-guest interaction between water-soluble pillar[6]arene(WP6)and a novel doxorubicin(DOX)-based drug-drug conjugate(G)is reported,in which the drug-drug conjugate is synthesized by conjugating anticancer drug DOX with another drug isoniazide via the acid-cleavable hydrazone bond.The obtained WP6⊃G micelles are stable under physiological conditions,whereas the cumulative release of DOX is approximate to 100%within 30 min at pH 5.5 by simulating the endo-lysosomal environment at 37℃.Therefore,this WP6-based prodrug micelles can achieve efficient DOX ac-cumulation in the acidic tumor cells within a short period of time,which is very important and valuable;meanwhile it can also reduce the unexpected premature burst release under physiological condition.Furthermore,cellular in-ternalization and localization experiments demonstrated that these prodrug micelles enter cancer cells mainly via endocytosis and can lead to significant drug accumulation in SKOV3 cancer cells,implying its promising future for cancer therapy. | Yu Cao Xiaochun Zou Shuhan Xiong Yan Li Yingzhong Shen Xiaoyu Hu Leyong Wang | 2015 | Chinese Journal of Chemistry2015,33,3: | 2 |
