Electrochemical Behavior of Cast Ti-Ag Alloys
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…

EFFECT OF HEAT TREATMENT ON STRUCTURE, MORPHOLOGY AND SURFACE PROPERTIES OF PALYGORSKITE
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…
Advances and Challenges of Wood Polymer Composites
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…
Complementarity and countercomplementarity in polynuclear copper(ii) complexes with R2NCH2CH(OH)CH2NR2 (R = H, CH3): crystal structures and magnetic study
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…
Determination of Asphalt Concrete Complex Modulus with Impact Resonance Test
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…
Assessing the zero‐field splitting in magnetic molecules by wave function‐based methods
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…
Sol-gel preparation of AlPO4–SiO2 glasses with high surface mesoporous structure
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…
Hygrothermal Effects on Interfacial Stress Transfer Characteristics of Carbon Nanotubes-reinforced Composites System
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…
Half-Metallic Properties and Stability of Ferromagnetic State in the Full-Heusler Alloys (Fe<I><SUB>x</SUB></I>Ru<SUB>1−<I>x</I></SUB>)<SUB>2</SUB>CrSi (0≤<I>x</I>≤1)
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…
Porphyrin dimers bridged by a platinum–diacetylide unit
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.
Microrod and Microtube Formation by Electrodeposition of Metal into Ordered Macropores Prepared in p-Type Silicon
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…
Thermal Conductivity Measurement of Tungsten Oxide Nanoscale Thin Films
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…
ATP-loaded immunoliposomes specific for cardiac myosin provide improved protection of the mechanical functions of myocardium from global ischemia in an isolated rat heart model
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…
