| 1 | A Novel Photocleaver with Long Wavelength Absorption-Highly Efficient Antitumor Agent: 4-(2-Diethylamino-ethylamino)-8-oxo-8H-acenaphtho-[1,2-b]pyrrole-9-carbonitrile显示文摘The photocleavage abilities of a novel family of compounds, 8-oxo-8%H%-acenaphtho pyrrole-9-carbonitrile and its derivatives(compounds 1—5) were evaluated with M13 mp18 single strand circular DNA. Only compound 1 with a diethylamine group could bind to DNA %via% electrostatic attraction and intercalation. At a concentration of 50 μmol/L, it could generate singlet oxygen to cleave circular DNA into linear DNA under the irradiation of long wavelength light(λ>400 nm). The antitumor {ability} of compound 1 was also evaluated in vitro, and its IC_ 50 on HeLa cells was as low as 6.8 μmol/L. | ZHANGZhi-chao LüZhe QIANXu-hong SHENGHui | 2005 | Chemical Research in Chinese Universities2005，21，4： | 1 |

| 4 | Wideband tunable passively Q-switched fiber laser at 2.8 μm using a broadband carbon nanotube saturable absorber显示文摘We propose and demonstrate a widely tunable passively Q-switched Ho^(3+)∕Pr^(3+)-codoped ZrF_4-BaF_2-LaF_3-AlF_3-NaF fiber laser operating in the 2.8 μm mid-infrared(MIR) waveband based on a single-walled carbon nanotube(SWCNT) saturable absorber(SA). The SWCNTs have diameters ranging from 1.4 to 1.7 nm. The modulation depth and saturation intensity of the SWCNT SA measured at 2850 nm are 16.5% and 1.66 MW∕cm^2, respectively. Stable Q-switched pulses with the shortest pulse duration of 1.46 μs and the maximum pulse energy of 0.43 μJ are achieved at a launched pump power of 445.6 mW. The combined use of a broadband SWCNT SA and a plane ruled grating ensures a broad continuously tuning range of 55.0 nm from 2837.6 to 2892.6 nm.The output powers, emission spectra, repetition rates, and pulse durations at different tuning wavelengths are also characterized and analyzed. Our results indicate that SWCNTs can be excellent broadband SAs in the 3 μm MIR region. To the author's knowledge, this is the first demonstration of a widely tunable carbon-nanotubeenabled passively Q-switched fiber laser operating in the 2.8 μm MIR waveband. | YANJIA Lü CHEN WEI HAN ZHANG ZHE KANG GUANSHI QIN YONG LIU | 2019 | Photonics Research2019，7，1： | 5 |

| 7 | Features and factors of radium isotopes in Tianjin’s typical estuaries显示文摘In order to characterize the features of radium isotopes in estuaries of Tianjin,a continuous survey and sampling of typical estuaries were conducted from 2013 to 2017 in this study.The activities of natural radioactive radium isotopes(^(223)Ra,^(224)Ra,and ^(228)Ra)in groundwater and surface water were measured by the radium-delayed coincidence counting(RaDeCC)system.The non-conservative behavior of the radium isotopes was investigated under hydrogeochemical conditions and urbanization.The results indicated that in terms of horizontal distribution,the activities of radium in groundwater(Hangu,Tanggu,and Dagang)showed an upward trend from north to south and demonstrated a higher figure than surface water(Haihe River and Duliujian River).Concerning the vertical distribution,the activitives of radium at a 15 m burial depth was higher than that at a 30 m burial depth in all measurements.The activities of radium isotopes in the study area increased with the increase of total dissolved solids,and their desorption behavior on Fe-Mn oxides was constrained by the redox intensity.Different hydrogeological conditions resulted in variations in the vertical profile of radium activities.The activity of radium was regulated by seasonal variation and precipitation in groundwater and surface water.In addition,the rapid urbanization has caused a significant impact on the features of radium isotopes in typical estuaries of Tianjin.Meanwhile,radium isotopes can be applied to reflect the impact of urbanization on surface watergroundwater systems.Clarifying and cleverly utilizing the relationship between behavior of radium isotopes and urbanization will promote the development of the Tianjin Binhai New Area in a healthy way. | Zhe Zhang Yingchun Dong Lixin Yi Xin Hao Yajie Zheng Tianxue Lü | 2023 | Acta Oceanologica Sinica2023，42，8： | 0 |
| 8 | Electrochemical performance of La_(2)NiO_(4+δ)-Ce_(0.55)La_(0.45)O_(2−δ)as a promising bifunctional oxygen electrode for reversible solid oxide cells显示文摘In this work,La_(2)NiO_(4+δ)-Ce_(0.55)La_(0.45)O_(2−δ)(denoted as LNO-xLDC)with various LDC contents(x=0,10,20,30,and 40 wt%)were prepared and evaluated as bifunctional oxygen electrodes for reversible solid oxide cells(RSOCs).Compared with the pure LNO,the optimum composition of LNO-30LDC exhibited the lowest polarization resistance(Rp)of 0.53 and 0.12Ω·cm^(2)in air at 650 and 750℃,respectively.The enhanced electrochemical performance of LNO-30LDC oxygen electrode was mainly attributed to the extended triple phase boundary and more oxygen ionic transfer channels.The hydrogen electrode supported single cell with LNO-30LDC oxygen electrode displayed peak power densities of 276,401,and 521 mW·cm^(−2)at 700,750,and 800℃,respectively.Moreover,the electrolysis current density of the single cell demonstrated 526.39 mA·cm^(−2) under 1.5 V at 800℃,and the corresponding hydrogen production rate was 220.03 mL·cm^(−2)·h^(−1).The encouraging results indicated that LNO-30LDC was a promising bifunctional oxygen electrode material for RSOCs. | Pengzhang Li Wei Yang Chuanjin Tian Wenyan Zhao Zhe Lü Zhipeng Xie Chang-An Wang | 2021 | Journal of Advanced Ceramics2021，10，2： | 2 |

| 10 | Boosting oxygen reduction activity and CO_(2) resistance on bismuth ferrite-based perovskite cathode for low-temperature solid oxide fuel cells below 600℃显示文摘Developing efficient and stable cathodes for low-temperature solid oxide fuel cells(LT-SOFCs) is of great importance for the practical commercialization.Herein,we propose a series of Sm-modified Bi_(0.7-x)Sm_xSr_(0.3)FeO_(3-δ) perovskites as highly-active catalysts for LT-SOFCs.Sm doping can significantly enhance the electrocata lytic activity and chemical stability of cathode.At 600℃,Bi_(0.675)Sm_(0.025)Sr_(0.3)FeO_(3-δ)(BSSF25) cathode has been found to be the optimum composition with a polarization resistance of 0.098 Ω cm^2,which is only around 22.8% of Bi_(0.7)Sr_(0.3)FeO_(3-δ)(BSF).A full cell utilizing BSSF25 displays an exceptional output density of 790 mW cm^(-2),which can operate continuously over100 h without obvious degradation.The remarkable electrochemical performance observed can be attributed to the improved O_(2) transport kinetics,superior surface oxygen adsorption capacity,as well as O_(2)p band centers in close proximity to the Fermi level.Moreover,larger average bonding energy(ABE) and the presence of highly acidic Bi,Sm,and Fe ions restrict the adsorption of CO_(2) on the cathode surface,resulting in excellent CO_(2) resistivity.This work provides valuable guidance for systematic design of efficient and durable catalysts for LT-SOFCs. | Juntao Gao Zhiyun Wei Mengke Yuan Zhe Wang Zhe Lü Qiang Li Lingling Xu Bo Wei | 2024 | Journal of Energy Chemistry2024，90，3： | 0 |

| 12 | Towards the selectivity distinction of phenol hydrogenation on noble metal catalysts显示文摘Selective hydrogenation of phenol to cyclohexanone is intriguing in chemical industry.Though a few catalysts with promising performances have been developed in recent years,the basic principle for catalyst design is still missing owing to the unclear catalytic mechanism.This work tries to unravel the mechanism of phenol hydro-genation and the reasons causing the selectivity discrepancy on noble metal catalysts under mild conditions.Results show that different reaction pathways always firstly converge to the formation of cyclohexanone under mild conditions.The selectivity discrepancy mainly depends on the activity for cyclohexanone sequential hy-drogenation,in which two factors are found to be responsible,i.e.the hydrogenation energy barrier and the competitive chemisorption between phenol and cyclohexanone,if the specific co-catalyzing effect of H 2 O on Ru is not considered.Based on the above results,a quantitative descriptor,E b(one/pl)/E a,in which E a can be further correlated to the d band center of the noble metal catalyst,is proposed by the first time to roughly evaluate and predict the selectivity to cyclohexanone for catalyst screening. | Shanjun Mao Zhe Wang Zhirong Chen Kejun Wu Kaichao Zhang Qichuan Li Huihuan Yan Guofeng Lü Guodong Huang Yong Wang | 2023 | Nano Materials Science2023，5，1： | 0 |
