Hollow polymeric spheres have been attracting increasing interest because of their potential applications， which range from targeted drug delivery to advanced functional materi- als.[1，2] Because of their hollow core structure， such polymeric spheres can encapsulate large quantities of guest moleculesD especially those spheres with functionalities within the empty coreDand release them at a later stage in a controlled man- ner. Although hollow polymeric spheres with dimensions in the micrometer and submicrometer regions are readily con- structedDby layer-by-layer deposition of polyelectrolytes onto a template core，[3±6] polymerizing monomers in lipid vesi- cles，[7，8] emulsion polymerization，[9，10] pH-induced micelliza- tion of a grafted copolymer，[11] and by the assembly of posi- tively charged polyelectrolytes and negatively charged nanoparticles[12]Dthe synthesis of hollow spheres 100 nm or less in size has only recently become the subject of research activity. Several different routes， such as the self-assembly of block copolymers in a selective solvent，[13，14] the deposition of polyelectrolytes on a decomplexable or soluble core，[15，16] and microemulsion (as well as miniemulsion) polymerization，[17，18] have been developed to form hollow polymeric nanospheres. Although some of these methods have been quite successful， these strategies require the core templates to be removed in order to create a hollow interior， or need large quantities of surfactants to form nanosized micelles. Furthermore， although the majority of the proposed applications of hollow nano- spheres or nanocapsules are concentrated in the biomedical field， most of the hollow polymeric spheres described to date are ill-suited for such purposes. Therefore， materials (in par- ticular for the surfaces of the hollow nanospheres) that are biocompatible， non-toxic， and sometimes also biodegradable， are highly desirable. Herein， we demonstrate a simple and di- rect method for fabricating hollow polymeric nanospheres with biocompatible and biodegradable macromolecules. In this approach， hollow polymeric nanospheres were formed in a completely aqueous system without the aid of surfactants， 展開(kāi)

Bimetallic dendrimer-encapsulated nanoparticles(DENs)are important materials，because they have demonstrated improvement in performance compared to the monometallic DENs in many systems when they are used as catalysts.This tutorial review focuses on the recent research advances in bimetallic DENs with respect to their synthesis，characterization，and applications as catalysts.Bimetallic DENs can be made mainly via three routes:co-complexation，sequential loading，and partial displacement.The research in bimetallic DENs has been significantly promoted by the advancement of characterization instruments.The performances of bimetallic DENs as homogeneous and heterogeneous catalysts in organic synthesis have been compared with both monometallic DENs and their physical mixtures.It is concluded that the synergistic electronic effect in bimetallic nanoparticles enhances their catalytic activities. 能翻譯多少都可以的 展開(kāi)

Practical applications of colossal magnetoresistive(CMR) oxides are limited by the large magnetic fields and/or low temperature required to observe a significant change in electric resistivity[1-5]. In recent years，research on tunneling magnetoresistance(TMR) is a very active field because of its scientific interest and potential technological applications[6].Polycrystalline Sr2FeMoO6 perovskite is a candidate for magnetic sensors owing to its high ferromagnetic transition temperature …（Tc~420K）and the half-metallic electronic band structure predicted theoretically [7]. The conduction electrons in this compound are expected to be highly spin-polarized even at room temperature. More recently， perovskite Sr2FeMoO6 with nanometer grain size showed large magnetoresistance(~20%) at a low magnetic field of 4k Oe and at room temperature[8].Dai et al.[9]observed two different ordered structures in polycrystalline Sr2FeMoO6 perovskite: the double perovskite and the superstructure with tripled c-axis(ST).In this paper， another new layered structure of body-centered tetragonal phase (BT) is reported for the polycrystalline magnetoresistive Sr2FeMoO6 sample. Ceramic samples of Sr2FeMoO6 were prepared by standard solid state reaction. Stoichiometric materials of SrCO3，F(xiàn)e2O3 and MoO3 were mechanically mixed， and then calcined at 950℃ for 4h in air.The calcined mixture was then ball-milled and made into pellets followed by sintering at 1250℃for 4h in carbon monoxide atmosphere.Transmission electron microscopy(TEM) specimens were prepared by mechanical polishing，dimpling and ion milling.Electron diffraction patterns were taken at 120kV using a Phillips CM12 electron microscope， and high resolution TEM imaging was conducted using JEOL 2010 microscope. Energy dispersion of X-rays(EDX) was conducted by TEM attached with EDAX PV9100. 展開(kāi)

PMMA has good compatibility with PVC due to specific interaction of a hydrogen bonding type between carbonyl groups (C=O) of PMMA and hydrogen from (CHCl) groups of PVC (Belhaneche-Bensemra et al.， 2002; Ramesh et al.， 2002). Zhou et al. (2001) studied the relationship between the coating thickness of PMMA on the surface of talc and mechanical properties of PMMA-g-talc/PVC composites， and found that there existed a critical thickness. Xie (2001) found that the PMMA coating on talc improved the dispersion of talc in the PVC matrix and enhanced the interfacial adhesion between talc and PVC. There appears to be a critical coating thickness of PMMA on the talc surface for optimum toughening. Quan et al. (2002) reported improved toughness and intension of the PVC composites filled with CaCO3/ACR core-shell complex particles prepared by in-situ emulsion polymerization of acrylic ester. In the present work， PMMA coated on the surface of CaCO3 nanoparticles by in-situ emulsion polymerization was characterized by FT-IR and 1H-NMR. The effects of PMMA thickness and particle fraction on the mechanical properties of PMMA-coated CaCO3 /PVC nanocomposites were also investigated. 展開(kāi)

Nano-sized Beta zeolites， with a crystal size of 80–100 nm， were synthesized via surface wet method. The nano-sized Hbeta zeolites exhibit much higher activity and stability in the Friedel–Crafts acylation of anisole and toluene with acetic anhydride than theconventional zeolites of largeparticle size.The smallcrystalsize of nano-sized zeolitesmay bringon more accessible activesites and then enhance the catalytic activity. The exposed pore openings in nano-sized zeolites allow a fast desorption of heavy products from the catalyst and can then reduce the occupancy of active sites by the adsorption of products ，this can then alleviate the catalyst deactivation and improve the catalyst stability deactivation and improve the catalyst stability. 急用 在線等 拒絕用自動(dòng)翻譯 因?yàn)檫@個(gè)誰(shuí)都會(huì) 如果有超級(jí)好用的自動(dòng)在線翻譯或軟件也可以推薦 展開(kāi)

A reversed-phase ion-pairing high-performance liquid chromatography (RP-HPIPC) method for the separation of a complex mixture of heparin-derived oligosacchrides has been developed by a stepwise optimization of the mobile phase， in which the concentration of ion-pairing reagent， mobile phase pH， and acetonitrile concentration were varied. The resolution of more than 30 oligosaccharide components was obtained， under optimized conditions， in an analysis time of less than 30 min. This represents the first RP-HPLC method that can separate a complex mixture of both small and large sulfated oligosaccharides in a single chromatographic step. The heparin-derived oligosaccharides， in this mixture， can also be separated under a second set of RP-HPIPC conditions using a volatile ion-pairing reagent， tributylammonium acetate， to aid in the recovery of individual sulfated oligosaccharides. Moreover， it was possible to replace sodium chloride gradient， required for eluting highly sulfated oligosaccharides， with a fixed， low concentration of a volatile salt， ammonium acetate， by utilizing an acetonitrile gradient. This solvent system might make it possible to directly interface this RP-HPIPC separation with mass spectral analysis. ??2003 Elsevier B.V. All rights reserved.

ThethreelevelcontrollersareproportionalwithKC=2.ThepressurecontrollershavetheAspendefaultsettingsofKC=20and?I=12min.Thetwocompositioncontrollersaretunedsequentially... The three level controllers are proportional with K C = 2. The pressure controllers have the Aspen default settings of K C = 20 and ?I = 12 min. The two composition controllers are tuned sequentially. Since the CCxD loop is blending two streams， its dynamics are fast with the composition deadtime the only dynamic element in the loop. So the distillate composition controller CCxD is tuned with the bottoms loop on manual. Then the bottoms composition controller CCxB is tuned with the distillate loop on automatic. Deadtimes of 3 min are inserted in the loops to account for composition measurement delays. Relay-feedback testing and Tyreus-Luyben settings give controller tuning constants K C = 0.40 and _ I = 37 min for the CCxB controller and K C = 22 and _ I = 13 min for the CCxD controller. 展開(kāi)
