Novel bent‐shaped mesogens based on substituted naphthalene‐2,7‐diol, possessing a double bond at the end of terminal branches, have been synthesized and characterized. A variety of banana‐mesophases has been found, depending on the type of lateral substitution. Increasing the length of the alkyl chain leads to the ap…
The BLM-system for studying the electrophysical properties of bilayer lipid membranes (BLM) was applied to investigate interactions between polyamidoamine (PAMAM) dendrimers and lipid bilayers. The cationic PAMAM G5 dendrimer effectively disrupted planar phosphatidylcholine membranes, while the hydroxyl PAMAM-OH G5 an…
New amphiphilic comb-dendritic block copolymers were developed as building blocks that self-assemble into stable vesicular structures with narrow size distribution.
Anodic polarization tests were performed in 0.9% NaCl and 1% lactic acid solutions to characterize the relationship between the corrosion behavior and the microstructures of cast Ti-Ag (5-40% Ag) alloys. The anodic polarization curves for the Ti-Ag alloys up to 17.5% Ag were similar to those for pure titanium in both…
对 Escherichiacoli 和克积极的葡萄球菌 aureus 微生物的 polyaniline (PAni ) 的优秀抗菌剂性能在黑暗、可见的轻条件下面被表明了。在 PAni 分子和细菌之间的静电的坚持可以为 PAni 的抗菌剂反应起一个很重要的作用，由于我们的调查，进行 PAni ，它的 composites/blends 被相信作为抗菌剂代理人的一种新类型有用，为改进人的健康和生活环境的自我清洗以及多功能的材料。
The dehydration, structural and morphological properties of palygorskite during heat treatment were studied by thermogra-vimetric and differential thermal analysis, X-ray diffraction and high resolution transmission electron microscopy. The results indicate that water is absorbed in the channel and outside surface of…
Wood flour and fiber have been blended with thermoplastic such as polyethylene, polypropylene, polylactic acid and polyvinyl chloride to form wood plastic composites (WPC). WPCs have seen a large growth in the United States in recent years mainly in the residential decking market with the removal of CCA treated wood d…
The syntheses, structural characterization and magnetic behavior of five new copper(II) polynuclear compounds with formulae [Cu4(mu2-CH3COO)2(mu-bdmap)2(micro(1,5)-dca)2(dca)2(H2O)2] 1, [Cu2(mu2-CH3COO)(mu-bdap)(mu(1,1,5)-dca)(mu(1,3)-dca)]n 2, [Cu4(mu2-CH3COO)2(mu-bdmap)2(mu(1,1)-NCS)2(NCS)2] 3, [Cu2(mu2-CH3COO)(mu-b…
A methodology is presented to determine the dynamic modulus and phase angle of hot-mix asphalt (HMA) with much simpler, nondestructive impact resonance (IR) test. Thirty-five HMA mixtures with varying aggregate and binder characteristics were tested with the IR and conventional dynamic modulus tests. A comparison of t…
Abstract The effect of spin‐orbit coupling is assessed through the spin‐orbit state interaction method. This method involves a two‐step procedure to include both dynamical electron correlation effects and spin‐orbit effects on the relative energies of the low‐lying electronic states. Accurate energies of the spin free…
Transparent and colorless amorphous silica–aluminum phosphate gels and glasses along the composition line, xAlPO4–(1−x)SiO2 were prepared via the sol-gel route using tetraethylorthosilicate (TEOS), aluminum lactate, and ammonium dihydrogen phosphate as precursors. The glass-forming range was significantly extended, co…
On the basis of the existence of strong bonding between carbon nanotubes (CNTs) and polymer matrix, and considering the axial and radial thermal expansion coefficients of CNTs as nonlinear functions of temperature changes, this article presents an analytical method to investigate hygrothermal effects on the interfacia…
We investigate the half-metallic properties and the stability of the ferromagnetic state in the alloys (FexRu1−x)2CrSi (0≤x≤1) with orderly and disorderly atomic arrangement based on the Heusler structure. It is predicted from the electronic structures that the ordered alloys are half-metals in the range of 1⁄3<x<3⁄4…
A series of butadiyne- and platinum diacetylide-bridged conjugated porphyrin dimers have been prepared; electrochemical and UV-vis absorption measurements on these compounds show that the butadiyne-bridge confers stronger porphyrin-porphyrin conjugation than the platinum diacetylide-bridge.
Copper and nickel electrodeposition into ordered macropores prepared in p-type silicon has been studied in aqueous solutions containing cupric and nickel ions, respectively. When a macroporous silicon template was cathodically polarized in 0.1 M cupric sulfate solution, copper was deposited preferentially at the pore…
The out-of-plane thermal conductivity of sputtered tungsten oxide thin films with thickness of 100 to 300 nm was measured by two omega method based on a new analytical model with consideration of the interfacial thermal resistance between the films and the substrate. The influence of the tungsten oxide structure on th…
Earlier demonstrated cardio-protection by ATP-loaded liposomes (ATP-L) was further improved by attachment of cardiac myosin-specific monoclonal 2G4 antibody onto the surface of ATP-L. ATP-IL were infused for 1 min duration before starting the global ischemia for 25 min followed by reperfusion for 30 min in an isolated…

An attempt has been made to review the influences of different structural factors on physical and water vapor transport properties of segmented shape memory polyurethane (SPU) for breathable textile, biomedical and many other industrial applications. The differences between ordinary, segmented and segmented shape memo…
Disc and rod shaped molecules which are completely miscible in the nematic phase were synthesised and the miscibility behaviour was investigated and confirmed by POM, DSC and XRD studies.
