In this paper, a flame retardant dimethyl-2-(methacryloyloxyethyl) phosphate (DMMEP) was applied onto wool fabrics by graft copolymerization technique in water media. The paper discussed the technological conditions of the formation of wool-g-DMMEP such as the pH value of reaction, reaction temperature and time etc. T…
In recent years, field emission display (FED) has been attracting much attention in the science community. It is a key technology for FED to design an excellent cathode structure. Rational designs can decrease cost and simplify fabrication technology in the preparation process of the cathode. A field electron emitter…
The dual-primal finite element tearing and interconnecting (FETI-DP) method is combined with the tree-co-tree splitting (TCS) method to analyze an electrical logging-while-drilling (LWD) tool. The FETI-DP method decomposes the original complex problem into subdomain problems and deals with them simultaneously using mu…
Softwood pulp was used to prepare dissolving pulp suitable for viscose fiber by three procedures (liquid hot water, sodium hypochlorite oxidation and alkali extraction). The impacts of main factors, such as temperature, reaction time, concentration and chlorine loading on the methylcellulose content and the polymeriza…
Effect of antimony on the microstructure, especially on the morphologies of rare earth-enriched phases, of mischmetal -containing AZ31 alloy was studied. The results showed that, by the addition of 0.8%Sb, the rare earth-enriched phases in AZ31-1.0％MM were transformed to dispersive tiny sphere-like Al-rare earth-Sb ph…
A previously published bidisperse pore model that considers in turn ion interdiffusion in macro- and micro-pores as competitive and step-by-step processes was evaluated. The ion exchange rate of H+/Ni2+ on gel and macroporous strong acid resins was measured under conditions favoring a particle diffusion controlled mec…
The effects of heat treatment on the microstructure and mechanical properties of Mg-3Sn-2Ca alloy were investigated. The results indicate that after solutionized at 500 °C for more than 24 h, the morphology of the CaMgSn phase in the alloy changes from the continuous and/or quasi-continuous nets to the particle-like s…
We have investigated the basic plasma density and electron tempereature by using the collisional radiative model, and also investigated the reactive radical species's densities for hydroxyl OH, superoxide anion O2*-and nitric oxide NO by using the ultravilioet absorption spectroscopy with the deuterium lamp in the atm…
A new resin from DSM Composite Resins offers wind turbine blade manufacturers the mechanical performance of epoxy resin with the processing advantages of unsaturated polyester resins. Luca Amato, Team Leader Composites & XCell, DSM Composite Resins, reports.
Extended abstract of a paper presented at Microscopy and Microanalysis 2012 in Phoenix, Arizona, USA, July 29 – August 2, 2012.
Cover: A new parallel algorithm for large-scale 3D SCFT simulations of inhomogeneous rod-coil copolymers is presented, with an interplay between microphase separation and orientational ordering and several new, intrinsic 3D morphologies, including a very specific hexagonally arranged columnar morphology that possesses…
In the 25thyear almost to the day in July, of my discovery of the low power damage in optical fiber also known as the fiber “fuse”, this paper reviews the advances made in our understanding and control this phenomenon.
Optical properties of aperiodic aggregates of gold nanospheres are studied. The optical response of these arrays can be explained in terms of the grating response of the array (photonic resonance) and the plasmonic response of the spheres (plasmonic resonance). In particular the couplings between the photonic and plas…

Calcium carbonate (CaCO3) is abundant in nature, and is also an important material applied in industry as pigment, filler material, etc. It is a challenge to control the desired CaCO3 properties for industry applications. In this study, three typical morphologies of CaCO3, calcite, aragonite and vaterite were prepared…
The microstructure and properties of the perovskite-type SrFeCoO3-δ (SFC) oxides synthesized by different methods were analyzed in detail in the paper. The oxide powders were synthesized by the citrate method (CM) and solid state reaction (SSR). X-ray diffraction (XRD) results reveal that the main crystal structure of…
The influences of ZnO photoanode structure on the properties of ZnO dye-sensitized solar cell were studied in this paper. Four kinds of ZnO photoanode films prepared from ZnO nanopowders, nanorods, nanosheets and aggregates were investigated. Their photovoltaic parameters were discussed and compared. ZnO cell consiste…
A new biodegradable copolymer of cellulose diacetate and poly(p-dioxanone) (PPDO) was prepared through a couple-grafting procedure. PPDO was functionalized with the isocyanate group, and then PPDO terminated with the isocyanate group was enabled to react with the hydroxyl groups of cellulose diacetate. The length of P…
L’intégration de fonctions optiques au sein de systèmes compacts et robustes permet d’envisager la réalisation de dispositifs répondant à des besoins issus de nombreux domaines d’applications. Au-delà des procédés d’hybridation qui restent aujourd’hui les plus répandus pour accéder à ces systèmes, la recherche de solu…
In this paper, experimental investigation carried out on a transformer to obtain frequency response data under various deformation/displacements physically simulated to study and identify the various parameters that influence the frequency responses is presented. Transfer Function using real-rational polynomial functi…
