Selenium nanoparticles (SeNPs) were prepared by using gum arabic (GA) as the stabilizer in a facile synthetic approach. The size, morphology, stability and antioxidant activity in vitro of the gum arabic-selenium nanocomposites (GA-SeNPs) were characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS), Fourier-transform infrared(More)
Microstructured optical fibers MOFs represent a promising platform technology for fully integrated photonic-plasmonic devices. In this paper, we experimentally investigate the properties of two MOF templates impregnated with silver nanoparticles via a high pressure chemical deposition technique. By comparing fiber templates with different air filling(More)
This paper presents the results of an analytical study on the seismic response of bridge in YingTan city. The main goal is to determine the capacity for various structural systems in order to evaluate the seismic vulnerability and to develop retrofit strategies. Another important objective is to investigate the effect of those response characteristics on(More)
A long-lived intramolecular charge-separated state in an electron-donor-acceptor molecule is characterized by time-resolved visible and infrared absorption spectroscopy. Bands that can be assigned to the negatively charged acceptor chromophore can be clearly observed in the time-resolved IR spectrum. In contrast, the electronic absorption spectrum of the(More)
The photochemistry of Fe(CO)5 (5) has been studied in heptane, supercritical (sc) Ar, scXe, and scCH4 using time-resolved infrared spectroscopy (TRIR). 3Fe(CO)4 ((3)4) and Fe(CO)3(solvent) (3) are formed as primary photoproducts within the first few picoseconds. Complex 3 is formed via a single-photon process. In heptane, scCH4, and scXe, (3)4 decays to(More)
The nature frequencies and mode shapes of flexible structures will be influenced by its large deformation and stress under the effect of loads. The numerical method is used in the dynamic analysis which has considered the influence of fluid-solid interaction, initial tension and the effect of large deformation. The results show that initial tension and(More)
Based on the distinctive feature and the complex construction with steel anchor box and concrete of XINJIANG Bridge in Yingtan, Jiangxi province, this paper analysed the stability of the bridge tower after the construction through a 3d model made by the finite element software ANSYS. The conclusion of comparing two different modulus of elasticity was, to(More)
