| 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 | Metals in water and surface sediments from Henan reaches of the Yellow River,China显示文摘The concentrations of Cd,Cr,Cu,Ni,Pb and Zn were determined in the water and surface sediments from the Henan reaches of the Yellow River.Twenty-three sampling sites along the Yellow River and its tributaries were selected.Generally,metal concentrations were found to decrease in sequences of Zn>Cu>Pb>Cr>Ni>Cd in water and Zn>Cr>Pb>Ni>Cu>Cd in sediments.High levels of metal concentration were determined at a few stations of the river and its tributaries,such as Yiluo River,Si River and Qin River.The pollution of the Yellow River by Cd,Cr,Cu,Ni,Pb and Zn can be regarded as much higher compared to the background values,US EPA criteria(1999) and China water quality criteria(2002) .For sediments,metal lev-els except Pb did not significantly exceed the average shale levels and backgrounds in several countries including China.Data analysis manifests that positive correlations were found between Cu,Ni and Zn in water,and Pb,Ni,Zn and Cr in sediments. The Pearson correlation coefficient analysis and Cluster analysis were provided to assess the possible contamination sources. The results indicate a general appearance of serious pollution along the banks of the Yellow River.The wastewaters discharged by the mine plants,smelter plants,power plants,battery plants,tannery plants,etc.,and sewage inputs from the cities along the river banks may be the sources of metals. | Feng, JingLan Wang, GuoLiang Sun, JianHui Sun, ShengPeng Liu, XiangFu | 2010 | Science China Chemistry2010，53，5： | 5 |
| 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 |

| 11 | Has the maximum of Solar Cycle 23 appeared?显示文摘In this note, we define firstly a compositive parameter as an index describing the level of solar activity in a solar cycle. The parameter is derived from a combination of the smoothed monthly mean sunspot number with the fluctuation of the associated monthly mean sunspot numbers to the smoothed one. Then, a method is developed for estimating the time of the appearance of a solar maximum based on the conception of similar cycles. An application ofthe method to the 23rd solar cycle shows that the maximum of the cycle should have appeared in the period from April to August 2000, and the descending phase of Cycle 23 has come. | WANG Jialong GONG Jiancun TONG Jizhou SUN Jinglan ZHU Cuilan | 2001 | Chinese Science Bulletin2001，46，19： | 1 |

| 15 | Effect of variable-angle trajectory structure on mechanical performance of CF/PEEK laminates made by robotic fiber placement显示文摘In comparison to the traditional fixed-angle trajectory,the variable-angle trajectory has a greater design space.However,it is a challenge to determine which common design curve structure is the most effective for improving mechanical performance.This work explores the effects of various design curves such as fixed-angle curve,linear curve,arc curve,sine curve,Bezier curve,and cubic polynomial curve trajectories on mechanical performance of laminates,including vibration modal performance and buckling performance.Genetic algorithm and improved NSGA-II algorithm are then used to optimize various curve structures.The results are confirmed utilizing thermoplastic Carbon Fiber(CF)/Polyether-Ether-Ketone(PEEK)laminates made by robotic fiber placement experiments.The relationship model between different mechanical performance and curve design variables is established.The optimization of variable-angle structure with mechanical properties as input variables is achieved.Meanwhile,a full-process angle-variable laying software platform from trajectory planning(CAD),trajectory optimization to manufacturing(CAM)is developed for facilitating the fiber placement application. | Shouzheng SUN Haiyang MEI Yang WANG Jiahai ZHANG Zhenyu HAN Jinglan GUO | 2022 | Chinese Journal of Aeronautics2022，35，12： | 1 |

| 17 | Construction of defect-containing UiO-66/MoSe_(2) heterojunctions with superior photocatalytic performance for wastewater treatment and mechanism insight显示文摘Metal-organic frameworks are recognized as promising multifunctional materials,especially metal-organic framework-based photocatalysts,which are considered to be ideal photocatalytic materials.Herein,a new type of UiO-66/MoSe_(2) composite was prepared using the solvothermal method.The optimum composite was selected by adjusting the mass ratio of UiO-66 and MoSe_(2).X-ray diffraction analysis showed that the mass ratio influenced the crystal plane exposure rate of the composite,which may have affected its photocatalytic performance.The composite is composed of ultra-thin flower-like MoSe_(2) that wrapped around cubic UiO-66,a structure that increases the abundance of active sites for reactions and is more conducive to the separation of carriers.The photocatalytic properties of the composite were evaluated by measuring the degradation rate of Rhodamine B and the catalyst’s ability to reduce Cr(VI)-containing wastewater under visible light irradiation.Rhodamine B was decolorized completely in 120 min,and most of the Cr(VI)was reduced within 150 min.The photochemical mechanism of the complex was studied in detail.The existence of Mo^(6+)and oxygen vacancies,in addition to the Z-type heterojunction promote the separation of electrons and holes,which enhances the photocatalytic effect. | Xiao Han Xiaoxuan Wang Jiafang Wang Yingjie Xie Cuiwei Du Chongfei Yu Jinglan Feng Jianhui Sun Shuying Dong | 2023 | Frontiers of Chemical Science and Engineering2023，17，4： | 0 |
