	Abstract:TS-1 zeolite with a Si/Ti ratio of 50 was synthesized by hydrothermal method, which was characterized by XRD, FTIR and SEM techniques. The synthesized TS-1 showed low catalytic activity for the decomposition of nitric oxide and soon completely deactivate by oxygen inhibition. While TS-1 was pretreated in hydrogen at 723K for 10h, 100% NO conversion to N2 could be obtained for almost 125 minutes, which was attributed to the superior capability to adsorb hydrogen of TS-1 zeolite. As expected, TS-1 exhibited high catalytic activity as well as perfect selectivity in the reduction of nitric oxide by excess hydrogen. At the temperature above 723K, all the 2000 ppm nitric oxide could be converted to nitrogen entirely. TS-1 was thought as a promising catalyst for nitric oxide reduction in excess hydrogen and a supposed mechanism was given for better understanding of the reaction process.

	2. Deposition, diffusion, and aggregation on small-world networks: A model for nanostructure growth on the defective substrate

	Abstract:Deposition, diffusion and aggregation (DDA) on a two-dimensional small-world network has been investigated by computer simulations. This model is characterized by two parameters: the clustering exponent $\alpha$ and long-range connection rate $\phi$. The results show that as $\alpha$ and $\phi$ vary there exists a continuous crossover in the fractal dimension $D_f$ from 1.65 to 2, which corresponds to the crossover from the DDA pattern to dense one. The change of the aggregation pattern results from the long-range connection in the network, which reduces the effect of screening during the aggregation. With primitive analysis, we obtain the expressions of the fractal dimension $D_f$ and the crossover point $\alpha_c$. The maximum value of $\alpha_c$ is 4. These results may be useful to describe the vapor deposition, molecular-beam epitaxy, and similar experiments on defective substrates.

	Abstract:A Maple package MiniIB is described, which is an implementation of the algorithm presented by Gerdt for the construction of minimal involutive bases for linear differential ideals. As a straightforward application, the minimal involutive bases of the determining system of classical Lie symmetry for some partial differential equation(s) are computed with package MiniIB.

	Abstract:The average value of g factor (i.e., ) of Cr4+ ions in forsterite (Mg2SiO4) is calculated with the cubic symmetry approximation from the complete high-order perturbation formula of g factor for 3d2 ion in cubic tetrahedral cluster. In the formula, the contribution to g factor from the charge-transfer mechanism (which is neglected in the crystal-field theory) is considered in addition to that from the widely used crystal-field mechanism. From the calculations, the reasonable observed value of is suggested (note: the experimental values of by various authors are scattered) and the important contribution of charge-transfer mechanism to g factor can be found.

	5. Studies of the g factor for Cr4+ ion in Bi4Ge3O12 crystal from crystal-field and charge-transfer mechanisms

	Abstract:The complete third-order perturbation formulas of g factors g// and g^ for 3d2 ions in tetragonal MX4 clusters have been established from a cluster approach. In these formulas, in addition to the contributions to g factors from the crystal-field mechanism in the crystal-field theory, the contributions from the charge-transfer mechanism are included. From these formulas, the g factors g// and g^ for Cr4+ ion in Bi4Ge3O12 crystal are calculated. The results are in agreement with the observed values. The calculated Dgi (i=// or ^) due to the charge-transfer mechanism is opposite in sign and about 20% in magnitude, compared with that due to the crystal-field mechanism. So, for the 3dn ions having high valence state in crystals, the reasonable explanations of g factors should take both the crystal-field and charge-transfer mechanisms into account.

	Abstract:A novel dual-coupling condenser for the fluorescent microscope was designed and used in some biophysics experiments. Proper glass, silica antireflective coat, carefully correcting of aberrations by software and dichroic beamsplitters were used to maintain optimal throughput and guarantee optimal homogeneity in the specimen plane. The average transmission of condensor is 31.3%. In given conditions, the density of flash energy is 13.85mJ/mm2 in the specimen plane. A result of photorelease experiment done by this condenser is given. It verifies that the condenser is suitable for coupling monochromator and flashlamp in the photorelease application.

	Abstract:To solve the problem of synchronization of two hyperchaotic systems with one single variable when the parameters of two hyperchaotic systems mismatch. Based on the methods of coupling and parameter identification method to find the right parameters of system, it proposed the relevant parameter identification and parameter compensation methods to solve the problem that the parameters mismatch.

	9. Pulsed Amperometric Detection of Thiols in Rat Striatum with Platinum Particles Modified Electrode

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:A new chemically modified electrode based on the immobilization of Pt particles is fabricated and exhibits electrocatalytic oxidation for L-cysteine (L-Cys), glutathione (GSH) and penicillamine (PEN) with relatively high sensitivity. It is also adaptable to HPLC for pulsed amperometric detection (PAD) of these thiols. PAD largely improves the detection sensitivity because the alternated polarizations can effectively clean and reactivate the electrode surface. It is shown that the peak currents of L-Cys, GSH and PEN are linear to their concentrations, with the calculated detection limit of 1.1´10-7, 1.8´10-7 and 3.8´10-7 mol L-1, respectively (S/N=3). The method has been successfully applied to assess the contents of L-Cys and GSH in rat striatal microdialysates. The average contents of the two analytes in rat striatum are 2.6´10-6 mol L-1 and 2.8´10-6 mol L-1 respectively.

	Abstract:A modified Olami-Feder-Christense(OFC)model on a square lattice with small-world architecture has been investigated. We find that our model displays power-law behavior.
