1Comparative pharmacokinetics of chlorogenic acid after oral administration in rats显示文摘The present study was aimed at the comparison of the pharmacokinetics of pure chlorogenic acid and extract of Solanum lyratum Thunb.The animals were allocated to two groups,and were administered chlorogenic acid or extract of S.lyratum Thunb.at a dose of 50.0 mg/kg orally.Blood samples were collected up to 8 h post-dosing.Plasma chlorogenic acid analyses were performed using an HPLC method with UV detector.The pharmacokinetic parameters were evaluated using non-compartmental assessment.Significant differences existed in the two groups for AUC 0 t,AUC 0 N and CLz/F.The reliable HPLC method was successfully applied to the determination of chlorogenic acid in rat plasma at dosage of 50.0 mg/kg.Wei Qi Ting Zhao Wen-Wen Yang Guang-Hou Wang Hua Yua Hai-Xiao Zhao Chen Yang Li-Xin Suna 2011Journal of Pharmaceutical Analysis2011,1,4:6
2Optimization of microstructures and magnetic properties of Sm(Co_(bal)Fe_(0.227)Cu_(0.07)Zr_(0.023))_(7.6) magnets by sintering treatment显示文摘Magnetic properties and microstructures of Sm(Co_(bal)Fe_(0.227)Cu_(0.07)Zr_(0.023_)_(7.6) sintered magnets were optimized by sintering treatment. Results show that the knee-point magnetic field, Hknee, is twofold up and the intrinsic coercivity Hcjincreases by 40%, ranging from 21.64 to 30.39 kOe at the cost of a little decrease of Brfrom 10.84 to 10.31 kGs with sintering temperature decreasing from 1488 to 1473 K. And the average domain width is narrower and more uniform for the specimen sintered at 1473 K than that of the specimen sintered at 1488 K. It is impressive that the density of lamellar phase increases from ~0.050 to ~0.058 nm^(-1) with the sintering temperature decreasing from 1488 to 1473 K. Moreover, the average cellular size is about ~84 nm for the magnets sintered at 1473 K, which is 80% of that of the magnets sintered at 1488 K(~97 nm). And the cell boundary width of the magnets sintered at 1473 K(~7 nm) is only half average width of the magnets sintered at 1488 K(~14 nm). It is found that the Cu content in the cell boundaries is much higher(~17 at%) in the magnets sintered at 1473 K compared to that of the magnets sintered at 1488 K(~10 at%). It can be concluded that smaller cells and narrower cell boundaries together with higher gradient of Cu content are key points for obtaining the optimum Hkneeand Hcj.Kuikui Songa Wei Suna Yikun Fang Shuai Wang Nengjun Yu Meiling Zhang Minggang Zhu Wei Li 2019Journal of Rare Earths2019,37,2:6
3Hyperbolic metamaterials: fusing artificial structures to natural 2D materials显示文摘Optical metamaterials have presented an innovative method of manipulating light.Hyperbolic metamaterials have an extremely high anisotropy with a hyperbolic dispersion relation.They are able to support high-k modes and exhibit a high density of states which produce distinctive properties that have been exploited in various applications,such as super-resolution imaging,negative refraction,and enhanced emission control.Here,state-of-the-art hyperbolic metamaterials are reviewed,starting from the fundamental principles to applications of artificially structured hyperbolic media to suggest ways to fuse natural two-dimensional hyperbolic materials.The review concludes by indicating the current challenges and our vision for future applications of hyperbolic metamaterials.Dasol Lee Sunae So Guangwei Hu Minkyung Kim Trevon Badloe Hanlyun Cho Jaekyung Kim Hongyoon Kim Cheng‑Wei Qiu Junsuk Rho 2022eLight2022,2,1:3
4Influence of mass-flow ratio of inner to outer secondary air on gas-particle flow near a swirl burner显示文摘The influence of mass-flow-rate ratio of inner to outer secondary air on gas-particle flow characteristics was determined in the near-burner region of a centrally fuel-rich swirl coal combustion burner.Velocity and particle volume flux profiles and normalized particle number concentrations were obtained.Peaks in tangential mean velocity and three-dimensional root-mean-square fluctuation velocities were found to decrease as the mass-flow-rate ratio increased.Moreover,the peaks in the mean axial velocities and particle volume flux near the wall increased,whereas those near the chamber axis decreased.Simultaneously,both recirculation zone and swirl number decreased as the mass-flow-rate ratio increased.Jianping Jing Chunming Zhang Wei Suna Jieruo Ana Jinsheng Bia Zhengqi Lib 2013Particuology2013,11,5:2
