| 1 | A New Index Developed for Fast Diagnosis of Meteorological Roles in Ground-Level Ozone Variations显示文摘China experienced worsening ground-level ozone(O_(2)) pollution from 2013 to 2019. In this study, meteorological parameters, including surface temperature(T_(2)), solar radiation(SW), and wind speed(WS), were classified into two aspects,(1) Photochemical Reaction Condition(PRC = T_(2)× SW) and(2) Physical Dispersion Capacity(PDC = WS). In this way, a Meteorology Synthetic Index(MSI = PRC/PDC) was developed for the quantification of meteorology-induced ground-level O_(2)pollution. The positive linear relationship between the 90 th percentile of MDA8(maximum daily 8-h average) O_(2)concentration and MSI determined that the contribution of meteorological changes to ground-level O-3 varied on a latitudinal gradient, decreasing from ~40% in southern China to 10%–20% in northern China. Favorable photochemical reaction conditions were more important for ground-level O_(2)pollution. This study proposes a universally applicable index for fast diagnosis of meteorological roles in ground-level O_(2)variability, which enables the assessment of the observed effects of precursor emissions reductions that can be used for designing future control policies. | Weihua CHEN Weiwen WANG Shiguo JIA Jingying MAO Fenghua YAN Lianming ZHENG Yongkang WU Xingteng ZHANG Yutong DONG Lingbin KONG Buqing ZHONG Ming CHANG Min SHAO Xuemei WANG | 2022 | Advances in Atmospheric Sciences2022，39，3： | 2 |
| 2 | Naphthalimide-rhodamine based fluorescent probe for ratiometric sensing of cellular pH显示文摘The pH values of lysosomes in cancer cells is slightly lower than that in normal cells, which can be used to distinguish cancer cells from normal cells. According to this, a naphthalimide-rhodamine based fluorescent probe(hereafter referred to as RBN) with a pK_a of 4.20 was designed and synthesized for ratiometric sensing of cellular pH via fluorescence resonance energy transfer(FRET), which can respond to different pH precisely through ratiometric fluorescence intensity(Ⅰ_(577)/Ⅰ_(540)). RBN can be employed to distinguish cancer cells from normal cells on the basis of different fluorescent response, in particular, RBN showed excellent water solubility and low cell toxicity, all these are quite significant for potential application in cancer diagnose and therapy. | Jia Wen Pengyi Xia Ziming Zheng Yongqian Xu Hongjuan Li Fengyu Liu Shiguo Sun | 2017 | Chinese Chemical Letters2017，28，10： | 2 |

| 9 | Monodisperse micro-spherical Sr_(2-z)Mg_(1+y)Y_(z)Al_(22-x)O_(36):xMn^(4+)red phosphors显示文摘With narrow red photoluminescence (PL) bands, tetravalent Mn^(4+) doped phosphors show promising prospect in commercial application to effectively expand color gamut of phosphor converted LED displays. Here, we report a type of Sr_(2-z)Mg_(1+y)Y_(z)Al_(22-x)O_(36):xMn^(4+) phosphors with regular cage-like micro-spherical morphologies. The micron size spherical precursors were synthesized with a propylene oxide (PO) driven fast sol–gel method. The cage -like spherical morphology is beneficial to efficiently trapping much incident light to enhance the PL of the phosphors. Being calcined at 1300 ℃, Sr_(2)MgAl_(21.978)O_(36):0.022Mn^(4+) only exhibits the internal quantum efficiency (IQE) of 24.91%. With the Mg^(2+)-Mn^(4+) codoping and Y^(3+)/Sr^(2+) substituting strategies, to fulfill charge balance and produce John-Teller distortion, IQE of Sr_(2-z)Mg_(1+y)Y_(z)Al_(22-x)O_(36):xMn^(4+) can be further improved up to 36.45%. The CIE color coordinates of Sr_(2-z)Mg_(1+y)Y_(z)Al_(22-x)O_(36):xMn^(4+) under near ultraviolet excitation can be stably fixed to (0.723, 0.227) at deep red region. It thus finds a potential application as pc-LED display with much broader color gamut than that of the NTSC standard. Therefore, Sr_(2-z)Mg_(1+y)Y_(z)Al_(22-x)O_(36):xMn^(4+) micron size spheres can be employed as promising red phosphors for high performance LED displays. | Jiannan Jia Mengting He Jun Wan Yuting Zhang Hai Guo Xianping Fan Xusheng Qiao Shiguo Chen | 2022 | Journal of Rare Earths2022，40，4： | 1 |

| 16 | Mesoporous silica nanoparticles-assisted ruthenium(Ⅱ) complexes for live cell staining显示文摘Ruthenium complexes which can bind to DNA via electrostatic and intercalation interactions producing strong luminescence have become ideal candidates for DNA staining. However, some of them such as Ru(phen)_3Cl_2 and Ru(phen)_2(dppz)Cl_2 could hardly cross the cellular membrane of live cells which limited their further interaction with DNA in live cells. To solve this problem, a potential approach is to find a proper vehicle for loading and delivery of these ruthenium complexes into live cells.Mesoporous silica nanoparticles(MSNs) with non-toxicity and good biocompatibility can be good candidates. More importantly,ruthenium complexes with positively charge could be loaded on negatively charged MSNs via electrostatic attractions to form MSNs-Ru hybrid. In vitro test demonstrated that MSNs had no side effects on the interactions between Ru complexes and DNA.Furthermore, it is found that the MSNs-Ru hybrid can enter into living human cervical cancer cells HeLa and stain the DNA while the corresponding ruthenium complexes alone could hardly cross the cellular membrane in the control experiment, demonstrating MSNs can be employed to be an efficient ruthenium complexes delivery nanomaterial for live cell staining. | Jia Wen Hui Yan Pengyi Xia Yongqian Xu Hongjuan Li Shiguo Sun | 2017 | Science China Chemistry2017，60，6： | 0 |
| 17 | Fluorescent probes for recognition of ATP显示文摘Adenosine 5'-triphosphate(ATP) not only participates in various physiological activities as the universal energy currency but also implicates in various pathological processes in living cells. Consequently,sensitive and selective detection ATP in live cells, tissues, as well as environmental samples, are urgently demanded. Due to the simple and convenient operation, economy cost, high selectivity for analyte, well biocompatibility and low cytotoxicity, fluorescent sensors for monitoring ATP have aroused great attention of researchers. In recent years, a large number of fluorescent sensors for detecting ATP have developed. This manuscript summarized most of these sensors and the interaction-mechanism between ATP and sensors, mainly including electrostatic interaction, p-p interaction, covalent bonding or hydrogen bond, or combinations of them, and the advantages of each strategy were also generalized.Here, a viewpoint of classification was shown where the sensors were divided into five typed ones according to the structure of probes used. | Ying Wu Jia Wen Hongjuan Li Shiguo Sun Yongqian Xu | 2017 | Chinese Chemical Letters2017，28，10： | 0 |
