A novel voltammetric sensor based on 3-aminopropyltriethoxysilanes (APTES) modified porous silicon electrode (APTES-PSE) was elaborated and used for determinating Ag in aqueous solution. Fourier transform infrared (FTIR) spectroscopy was performed to confirm the modification of APTES. The surface morphologies of PSE and APTES-PSE were characterized by atom force microscopy (AFM). Electrochemical property of PSE and modified electrode was studied using electrochemical impedance spectroscopy (EIS). Under the optimal experimental conditions, the cathode peak current intensity of APTES-PSE linearly changes with logarithm of Ag concentrations over the wide range from 1×10-3 mol L-1 to 1×10-7 mol L-1, with a detection limit of 3×10-8 mol L-1. Meanwhile, the APTES-PSE showed a good sensitive to Ag in the aqueous solution and which is attributed to the preferential chelation of N atoms of APTES. These results suggest that the choice of PSE as the substrate of the voltammetric sensor might be a very promising means for integrated analytical sensing.

Abstract. With HFHIPS as the substrate, through the double-screw extrusion processing technology of blending modification, add the titanium dioxide (TiO2) and brightener (ZB) into the HFHIPS. Change the content of TiO2 and ZB of the substrate respectively, study the influence of content on the HFHIPS Reflective materials with microstructure on surface, Including reflectivity, whiteness, impact strength and tensile strength. The results show that, when add the TiO2 and ZB into the HFHIPS, reflectivity and whiteness were improved obviously. Reflectivity can reach 95.3%, at the same time, the intensity will not have a significant reduction; But when the content reaches a certain value, TiO2 and ZB will cover each other, this will reduce the reflectivity and whiteness.

Abstract. The Fe50Co50 magnetic films were prepared by magnetron sputtering onto glass substrates. The structural and magnetic properties of the films were investigated as a function of annealing temperature and annealing time. It is found that the films have the better crystallization orientation after annealing. The in-plane coercivity Hc reduces with increasing annealing temperature and annealing time. Coercivity reaches the minimum in the sample annealed at 600˚C for 2h. Meanwhile, the saturation magnetization Ms increases with increasing annealing temperature as a whole. A scanning probe microscope was used to scan surface morphology and magnetic domain structures. After annealing, the domain size becomes larger and the contrast of domains increases..

Abstract Excited states of the positive-parity intruder band in 118Sn have been studied via the 116Cd(7Li, 1p4n) reaction at 7Li energy of 48 MeV using techniques of in-beam -ray spectroscopy. This intruder band has been observed up to 7187 keV with spin (16+). The structural evolution of this intruder band with increasing angular momentum has been discussed in terms of the aligned angular momentum and the ratio of the E-Gamma Over Spin (E-GOS) curve. Key words intruder band, quasiparticle alignment, structural evolution PACS 21.10.Re, 23.20.Lv, 27.60.+j 1

This e-book is devoted to Global Optimization algorithms, which are methods for finding solutions of high quality for an incredible wide range of problems. We introduce the basic concepts of optimization and discuss features which make optimization problems difficult and thus, should be considered when trying to solve them. In this book, we focus on
