Study on Chemiluminescence Reactions of Lucigenin and Reductants by Flow Injection Analysis

Preceding studies involved two kinds of chemiluminescence (CL) reactions of Lucigenin(Lu ),one was the reaction of Lu with H=O, catalyzed by metal ions, the other was that ofLu with organic reductants such as glucose, uric acid and so on.We found that Mo (Ill),V (11 ),U (ill),W (ill),Cr (11 ),Ti (ill) and Fe (11 ), whichwere produced on-line by passing Mo (VI),V (V ),U (VI), W (VI), Cr (VI,lll),Ti (N) andFe (ill) through a micro Jones column', can react with Lu to generate strong …     

Solvothermal synthesis of hollow Eu2O3 microspheres using carbon template-assisted method

This work presents a sol-gel carbon sphere template-assisted method of hollow Eu₂O₃ microspheres preparation. X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), as well as photoluminescence (PL) were used to characterise the products. The formation of hollow structure Eu₂O₃ microspheres can be assigned to a sol-gel carbon template. Furthermore, this work may confirm that the precursor sol-gel can be loaded onto the inner as well as the outer surface of carbon templates similarly as ions and nanocrystals. The presented method can afford a simple and efficient technique to obtain a series of hollow structure inorganic materials with high productivity.     

Remark on stability of rarefaction waves to the one‐dimensional compressible Navier–Stokes equations with density‐dependent viscosity coefficient

In this paper, we study one‐dimensional compressible isentropic Navier–Stokes equations with density‐dependent viscosity. We can obtain the asymptotic stability of rarefaction waves for the compressible isentropic Navier–Stokes equations when the power of viscosity coefficient , which enlarge the range of α in the article [Jiu Q, Wang Y, Xin ZP, Communication in Partial Differential Equations 2011; 36: 602‐634].

Transient energy density distribution of a rod under high-frequency excitation

Energy finite element analysis (EFEA) is an efficient way to solve high-frequency structural dynamics response problems. Up to now, EFEA has been used to deal with time-independent vibration problems. However, it is still necessary to understand the time dependent details of energy density distribution of a structure. To study the transient response of a rod under high-frequency sinusoidal excitation, the transient energy density governing equation for a rod is presented. The governing equation is solved, and the solution is verified using an analytical method. Example application to a rod is presented to illustrate the feasibility.
