| 1 | Growth response and toxic effects of three antibiotics on Selenastrum capricornutum evaluated by photosynthetic rate and chlorophyll biosynthesis显示文摘The effects of three types of antibiotics (erythromycin,ciprofloxacin and sulfamethoxazole) on the photosynthesis of freshwater algae,Selenastrum capricornutum Printz,were investigated by determining the growth rate,chloroplast pigments content,seven main precursors (including δ-aminolevulinic acid,porphobilinogen,uroporphyrinogen III,coproporphyrinogen III,protoporphyrin IX,Mg-proporphyrin IX and protochlorophyllide),and photosynthetic rate during chlorophyll biosynthesis.The antibiotics significantly decreased the growth rate,chlorophyll content,and photosynthetic rate.Erythromycin induced a decreasing effect at a concentration of 0.06 mg/L,while ciprofloxacin and sulfamethoxazole achieved the same results at concentrations higher than 1.5 mg/L.Only erythromycin significantly inhibited chlorophyll biosynthesis,which indicated that it was considerably more toxic to S.capricornutum than ciprofloxacin and sulfamethoxazole,and may pose a high potential risk to aquatic ecosystems. | Binyang Liu Weiqiu Liu Xiangping Nie Chao Guan Yufeng Yang Zhaohui Wang Wei Liao | 2011 | Journal of Environmental Sciences2011，23，9： | 11 |
| 2 | Controlled preparation and characterization of nano-sized hexagonal Mg(OH)_2 flame retardant显示文摘Nano-sized hexagonal magnesium hydroxide(Mg(OH)_2) with good dispersibility was synthesized by a double injection-hydrothermal method,utilizing polyvinylpyrrolidone(PVP) as an additive and with optimized processing parameters.SEM and BET analysis showed that the mean particle size and specific surface area of the Mg(OH)_2 particles were 174 nm and 50.77 m^2/g,respectively.The FT-IR spectra and the XRD patterns showed that PVP was adsorbed on the surface of the Mg(OH)_2 crystal,thus effectively limiting particle agglomeration and hindering crystal growth along the(101) plane.TGA showed a decrease in the decomposition temperature and an increase in the weight loss of the Mg(OH)_2 particles due to addition of PVP. | Huaxiong Fang Tao Zhou Xiangping Chen Simin Li Guangshan Shen Xiaoyan Liao | 2014 | Particuology2014，12，3： | 10 |
| 3 | Influence of structural defects on the optical properties of strongly coupled Au nanoshell arrays显示文摘The effects of different defects on optical properties and plasmon resonances properties of Au nanoshell arrays were investigated by using the finite-difference time-domain(FDTD) theory.It is found that the optical properties of the nanoshell arrays are strongly influenced by different defects.We show that when the hollow Au nanoshell arrays are placed in air,there is a wide photonic band gap(PBG) in the infrared region,but the band gap becomes narrower as we introduced different defects.Based on the distributions of electric field component E z and the total energy distribution of the electric and the magnetic field,we show that there exhibit dipoles field distributions for the plasmon mode at the long-wavelength edge of the band gap,but composite higher order modes are excited at the short-wavelength edge of the band gap.The plasmon resonant modes also can be controlled by introducing defects. | ZHOU Xin FANG JianShu LIAO XiangPing ZHU QianQuan LIU ZhiMin TANG Bin | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，9： | 2 |
