A 52-year-old woman physician developed recurrent erythema multiforme. Occupational and environmental exposure assessment suggested a disinfectant containing polyhexamethylenebiguanide hydrochloride (PHMB), Phagosept. Elimination of the product was followed by disappearance of symptomatology. Literature search reveale…
Most reliability issues in interconnect systems occur at a local scale and many of them include the local build‐up of stresses. Typical failure mechanisms are electromigration and stress voiding in interconnect lines and fatigue in surface acoustic wave devices. Thus a local probe is required for the investigation of…
Abstract. Mn0.67Zn0.33Fe2O4 nanoparticles with size ranging from 20 to 80 nm have been synthesized using the modified oxidation method. The Curie temperatures for all the samples are found to be within 630 ± 5 K suggesting that there is no size-dependent cation distribution. Mössbauer studies on the synthesized nanopa…
Silicone vulcanizates were obtained by crosslinking of poly(dimethyl-siloxane-a,w-diols) (Polastosil, Table 1) with poly[(methyl, phenyl) hydrosiloxanes] (PMHS, PMFHS) of different functionality (Table 2) in the presence of tin catalyst: dibutyltin dilaurate (DBTL). PMHS and PMFHS of linear and branched random structu…
Copper nanowires have been synthesized using potentiostatic electrodeposition within the confined nanochannels of a porous ion-crafted membrane. Morphology of electrodeposited copper nanowires has been studied using scanning electron microscopy. These nanowires have uniform diameters of about 100 nm, which corresponds…

Mg alloys have been widely used in automobile and electronic industries because of high specific strength, good castability, etc.However, molten Mg alloys will burn rapidly in air if not protected.To solve this problem, the molten metal should be protected from oxidation by blanketing the surface with flux or protecti…
Si3N4/SiO2 composites were prepared with pressureless sintering. It was found that the Si3N4 particle was effective to suppress the crystallization of cristobalite in the Si3N4/SiO2 composites and contributed to the improvement of the mechanical properties. After sintered at 1370℃for 2h, the flexural strength of the c…
Carbon nanotubes(CNTs) supporting ferric oxide(Fe_2O_3) as composite nano-particles catalyst was prepared by the liquid phase precipitation method,and was characterized by transmission electron microscopy(TEM) and X-ray photoelectron spectroscopy(XPS).The effect of Fe_2O_3/CNTs composite nano-particles catalyst on the…
Insulators’ icing is one of the severe problems for external insulation of transmission lines and there are a lot of reports about power outages caused by flashover of the ice-covered insulators from all over the world. Therefore, it is very significant to investigate the icing process and the icing performances of in…
Types of fouling in heat exchanger and their affected factors are summarized.Some usual cleaning methods are analyzed.
The effect of flow behavior on degradation of de-NOx catalyst is experimentally and numerically investigated. The de-NOx rate for used catalysts is evaluated using laboratory-scale test apparatus. and the flow behavior in a honeycomb rectangular tube of the catalyst is studied by direct numerical simulations (DNS). Th…
In order to assess the geothermometric potential of the Na2(Mn2-2xFe1+2x)(PO4)3 system (x = 0-1), which represents the compositions of natural weakly oxidized alluaudites, we performed hydrother- mal experiments between 400 and 800� C, at 1 kbar, under an oxygen fugacity (f(O2)) controlled by the Ni-NiO (NNO), Fe2O3-F…
Raman spectra of carbon nanowalls grown by microwave plasma enhanced chemical vapor deposition were analyzed. A typical Raman spectrum of carbon nanowalls exhibits three main bands, i.e., the G, D and D’ bands centered at about 1580, 1350 and 1620 cm-1, respectively. The peak intensity ratio of D to G band (ID/IG) was…
Thermal conductivity of doped MNiSn (M = Ti, Zr) half-Heusler alloys has been investigated from room temperature to 1000 K. Nonnegligible increase of thermal conductivity was observed for all the samples at high temperature. The temperature dependence appeared to the corresponding to the change of electrical propertie…
Recently, four canonical forms have been developed and applied to the dynamics and stability analysis of symmetric frames. In this paper, hyper-symmetric matrices and specially structured matrices are defined and efficient methods are proposed for the eigensolution of such matrices. Applications are extended to hyper-…
Poly(N‐acryloyl‐N′‐methylpiperazine‐co‐methyl methacrylate)s, poly(methyl methacrylate), poly(N‐acryloyl‐N′‐methylpiperazine), have been prepared by free radical polymerization using AIBN as initiator. Blends of the homopolymers in similar composition with those of the copolymers have been prepared by casting films fr…
The latest progresses of the series of research on the trapper of nitrosamines are reported in this paper, involving the attempts to elevate the selective adsorption of zeolites through enhancing adsorbent‐adsorbate interaction, in order to prepare the new functional nanoporous materials with high efficiency to elimin…
The kinetics of the martensitic transformation in a CuAlMn shape memory alloy (SMA) has been studied using the acoustic emission (AE) technique. It is demonstrated that the volume fraction of martensite as a function of time and temperature can be derived from the measured AE power. The fraction data obtained can be d…
Three kinds of fluorescent powders were separated by means of organic liquid-liquid extraction for the recycling purpose. The effect of surfactant concentration on the separation of the fluorescent powders was observed. In this study, the effect was analyzed by observing aggregate structure of the green and blue fluor…
