| 1 | Degradation potential of ofloxacin and its resulting transformation products during Fenton oxidation process显示文摘The degradation of ofloxacin(OFX)in the aqueous solution by Fenton oxidation process was investigated in the present study.The optimum operating conditions for the degradation of OFX in our system was determined.More importantly,the degradation pathways on a basis of the identification of transformation products during the degradation of OFX were proposed,which revealed that the initial degradation step could be associated with the decarboxylation at the quinolone moiety.Moreover,the detachment of the F element during the Fenton oxidation process has also been detected.Since the carboxylic group within OFX has been considered as an important bridge for binding quinolones with the DNA gyrase target,the decarboxylation process would offer insights into the reduction of antibacterial potentials. | Yunqing Pi Jinglan Feng Mengke Song Jianhui Sun | 2014 | Chinese Science Bulletin2014，59，21： | 10 |
| 2 | Activation of mitogen-activated protein kinases in satellite glial cells of the trigeminal ganglion contributes to substance P-mediated inflammatory pain显示文摘Inflammatory orofacial pain,in which substance P (SP) plays an important role,is closely related to the cross-talk between trigeminal ganglion (TG) neurons and satellite glial cells (SGCs).SGC activation is emerging as the key mechanism underlying inflammatory pain through different signalling mechanisms,including glial fibrillary acidic protein (GFAP) activation,phosphorylation of mitogen-activated protein kinase (MAPK) signalling pathways,and cytokine upregulation.However,in the TG,the mechanism underlying SP-mediated orofacial pain generated by SGCs is largely unknown.In this study,we investigated whether SP is involved in inflammatory orofacial pain by upregulating interleukin (IL)-1β and tumour necrosis factor (TNF)-α from SGCs,and we explored whether MAPK signalling pathways mediate the pain process.In the present study,complete Freund’s adjuvant (CFA) was injected into the whisker pad of rats to induce an inflammatory model in vivo.SP was administered to SGC cultures in vitro to confirm the effect of SP.Facial expression analysis showed that pre-injection of L703,606 (an NK-1 receptor antagonist),U0126 (an inhibitor of MAPK/extracellular signal-regulated kinase [ERK] kinase [MEK] 1/2),and SB203580 (an inhibitor of P38) into the TG to induce targeted prevention of the activation of the NK-1 receptor and the phosphorylation of MAPKs significantly suppressed CFA-induced inflammatory allodynia.In addition,SP promoted SGC activation,which was proven by increased GFAP,p-MAPKs,IL-1β and TNF-α in SGCs under inflammatory conditions.Moreover,the increase in IL-1β and TNF-α was suppressed by L703,606,U0126 and SB203580 in vivo and in vitro.These present findings suggested that SP,released from TG neurons,activated SGCs through the ERK1/2 and P38 pathways and promoted the production of IL-1β and TNF-α from SGCs,contributing to inflammatory orofacial pain associated with peripheral sensitization. | Yanyan Zhang Ning Song Fei Liu Jiu Lin Mengke Liu Chaolan Huang Daqing Liao Cheng Zhou Hang Wang Jiefei Shen | 2019 | International Journal of Oral Science2019，11，3： | 6 |
| 3 | Degradation of the antibiotic sulfamonomethoxine sodium in aqueous solution by photo-Fenton oxidation显示文摘In this study, photo-Fenton oxidation was applied to degradation of sulfamonomethoxine sodium (SMMS) in aqueous solution. The operation parameters of pH, temperature, and concentrations of H2O2, Fe2+ and SMMS were investigated. The optimum conditions for the photo-Fenton process were determined as follows: [SMMS]=4.53 mg/L, pH 4.0, [H2O2]=0.49 mmol/L, [Fe2+]= 19.51 μmol/L and T=25°C. Under these conditions 98.5% of the SMMS degraded. The kinetics were also studied, and degradation of SMMS by the photo-Fenton process could be described by first-order kinetics. The apparent activation energy was calculated as 23.95 kJ/mol. Mineralization of the process was investigated by measuring the chemical oxygen demand (COD), and the COD decreased by 99% after 120 min. This process could be used as a pretreatment method for wastewater containing sulfamonomethoxine sodium. | SUN JianHui FENG JingLan SHI ShaoHui PI YunQing SONG MengKe SHI Yan | 2012 | Chinese Science Bulletin2012，57，5： | 2 |

| 5 | Carbon nanotube-based photothermal membrane for efficient cold air heating and removal of particulate matter and airborne bacteria显示文摘Indoor heating results in high energy consumption and severe atmospheric pollution.Although the development of solar air heaters provides a sustainable route for indoor thermal comfort,such heaters still face challenges in terms of adequate heat exchange and filtering of atmospheric pollutants.Inspired by solar-driven interfacial evaporation,we propose a multifunctional carbon nanotube-based photothermal membrane for efficient cold air heating and purification via ventilation.Carbon nanotubes endow the membrane with high light absorption and thermal conversion capabilities,thereby sufficiently heating the approaching cold air.With the hierarchical structure formed by phase inversion,the thin upper skin of the composite membrane intercepts micropollutants via the size-sieving effect,whereas the finger-like pores and interpenetrating macrovoids inside the membrane ensure that the heated clear air passes through quickly.A proof-of-principle experiment indicated a cold airflow of 1 L/min across the membrane,yielding a temperature increase of ca.37°C as well as a PM 2.5 rejection always higher than 93%.Further antibacterial experiments demonstrated that the membrane effectively removed airborne bacteria.This multifunctional carbon nanotube-based photothermal membrane with specific microstructures not only improves the indoor living quality but also provides a sustainable development scheme to coordinate the relationship among energy utilization,building heating,and air purification. | Weichao Dong Lina Huang Xiangju Song Yan Zhang Mengke Liu Zhenzhen Ren Long Pang Hui Peng Heqing Jiang | 2024 | Green Carbon2024，2，1： | 0 |
| 6 | Comparative analysis of DNA-SIP and magnetic-nanoparticle mediated isolation (MMI) on unraveling dimethoate degraders显示文摘Microorganisms are crucial in the bioremediation of organophosphorus pesticides. However, most functional microorganisms (> 99%) are yet to be cultivated. This study applied two cultivation-independent approaches, DNA-SIP and magnetic-nanoparticle mediated isolation (MMI), to identify the functional microorganisms in degrading dimethoate in agricultural soils. MMI identified five dimethoate degraders: Pseudomonas, Bacillus, Ramlibacter, Arthrobacter, and Rhodococcus, whereas DNA-SIP identified three dimethoate degraders: Ramlibacter, Arthrobacter, and Rhodococcus. Also, MMI showed higher resolution than DNA-SIP in identifying functional microorganisms. Two organic phosphohydrolase (OPH) genes: ophC2 and ophB, were involved in dimethoate metabolism, as revealed by DNA-SIP and MMI. The degradation products of dimethoate include omethoate, O,O,S-trimethyl thiophosphorothioate, N-methyl-2-sulfanylacetamide, O,O-diethyl S-hydrogen phosphorodithioate, O,O,O-trimethyl thiophosphate, O,O,S-trimethyl thiophosphorodithioate, and O,O,O-trimethyl phosphoric. This study emphasizes the feasibility of using SIP and MMI to explore the functional dimethoate degraders, expanding our knowledge of microbial resources with cultivation-independent approaches. | Luning Lian Yi Xing Dayi Zhang Longfei Jiang Mengke Song Bo Jiang | 2024 | Frontiers of Environmental Science & Engineering2024，18，1： | 0 |

| 8 | Deciphering the degradation discrepancy in Ni-rich cathodes with a diverse proportion of[003]crystallographic textures显示文摘The crystal plane plays a very important role in the properties of Ni-rich cathodes.[003]crystallographic texture regulation has been proven to improve structural stability,and yet,the discrepancy of particles with different exposed ratios of[003]in structural attenuation has not been clarified.Herein,we have unraveled comprehensively the structural decay difference for Ni-rich cathodes’primary particles with the different percentages of exposed[003]by regulating the precursor coprecipitation process.The findings based on structural characterization,first-principles calculations,finite element analysis,and electrochemical test reveal that the length and width of particles represent[110]and[003]directions,respectively,and show that cathode particles with a higher[110]/[003]ratio can effectively inhibit structure degradation and intergranular/intragranular crack formation owing to the low oxygen vacancy formation energy on(003)planes and the small local stress on secondary/primary particles.This study may provide guidance for the structural design of layered cathodes. | Lang Qiu Mengke Zhang Yang Song Zhenguo Wu Yan-Fang Zhu Jun Zhang Dong Wang Hai-Yan Hu Hong-Wei Li Hang-Rui Liu Xin-Bei Jia Jian Peng Shuangqiang Chen Zuguang Yang Yao Xiao Xiaodong Guo | 2023 | Carbon Energy2023，5，7： | 0 |
