Porphyrins are an important large class of macro-cyclic compounds,and exist extensively in nature and living bodies. The unique chemical structure of porphyrins endows them with superior physical,chemical and optical properties that make them to have broad applications in many fields. However,free porphyrins have intr…
AB ST R ACT : The purpose of this paper is to determine the effect of NaF and firing temperature on the dielectric properties (dielectric constant and dielectric loss) of talc, which is used in the electrical and electronic industries as a circuit element. A detailed characterization of the samples was made by XRD, FT…
In this work, we synthesized high-quality InAs nanowires by a convenient chemical vapor deposition method, and developed a simple laser heating method to measure the thermal conductivity of a single InAs nanowire in air. During the measurement, a focused laser was used to heat one end of a freely suspended nanowire, w…
A kind of water–oil separation material was fabricated by depositing the mesoporous microspheres (MS) on filter paper. MS had been prepared via surfactant-template method and modified by octyltriethoxysilane. The diameter of microspheres was in the range of 200–800 nm. There were uniform mesopores in the microspheres,…
Alkyd resins are viscous, tacky materials that are difficult to handle. Most often, these handling problems are overcome by dissolving the resins in organic solvents, which evaporate into the atmosphere as volatile organic compound (VOC), giving rise to regulations. A reactive diluent is a compound that acts as a solv…
Nanocapsules containing polyaniline homodispersed in n-octadecane(n-Oct) were synthesized by free radical emulsion polymerization and in situ polymerization using poly(methyl methacrylate-co-allyl methacrylate)(P(MMA-co-AMA)) as a shell, in which polyaniline was used as the nucleating agent. Furthermore, the surface m…
Holographic recording characteristics of the unmodified and modified by sodium citrate Fe3O4-nanoparticles dispersed in conventional organic photopolymers were studied.The hybrid photopolymer exist the mutual diffusion process and anti-wrinkle effect in the experimental system was verified.The results of the experimen…
The 6.5 mm thick plate of a multiphase steel(0.23C-1.9Mn-1.6Si%) composed of intercritical ferrite, martensite and well- distributed retained austenite was obtained by an optimized IQP process. Tensile strength of this kind of multiphase steel is higher than 1000MPa. Microstructure of the steel was characterized by me…
Microstructure and electrical properties of La2 O3-doped ZnO-Bi2 O3 thin films prepared by sol–gel process have been investigated.X-ray diffraction shows that most diffraction peaks of ZnO are equal,and the crystals of ZnO grow well.Scanning electron microscopy and atomic force microscopy results indicate that the sam…
Aligned carbon nanotube(CNT) arrays are the important forms of CNT aggregates, which can be controllably synthesized by chemical vapor deposition(CVD) methods. And they are the bridges that bring the excellent properties of CNT from nano-world to macro-world. Here this review gives a brief overview of the control grow…
