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.
Abstract In this study we provide experimental methods to identify the magnetic resonance of split ring resonantors (SRR) at the microwave frequency regime. Transmission measurements were performed on both single SRR unit cell and periodic arrays of SRRs. The magnetic response of the SRR structure was demonstrated by…
Here we report the synthesis, characterization and hydrogelation of polymers consisting of pamidronate, a useful therapeutic agent.
Supramolecular polymer-hybrid nanotubes have recently emerged the self-assembly of coil-ring-coil block-copolymers and the surface-initiated polymerization from self-assembled peptide nanotubes. The article describes recent developments in designing functional organic nanotubes.
The crystal structure of a new monomeric Fe(II) spin-crossover thiocyanate complex with a polypyridyl triazine-based ligand is reported at three temperatures. Spectroscopic, thermal and magnetic studies are presented that allowed the characterization of the thermal spin-crossover experienced by this compound and its c…
Photoluminescence (PL) and optical gain measurements have been performed for single crystals of thiophene/phenylene co-oligomer at room and low temperatures. Broad PL bands are transformed to be an ensemble of several spectrally narrower vibronic peaks with decreasing temperature. Very sharp lines as narrow as ∼3meV a…
In today's material world it is agreed that a complete understanding of the solidification path and of the resulting microstructure can only be obtained by treating the alloys as mathematical systems, followed by validation of the models through definitive experiments. This paper will attempt to review the main recent…
The lanthanide(III) complexes [Ln(LH2)(NO3)3] 1-11(La-Er), 15(Y) and [Ln(LH2)(NO3)2(H2O)](NO3) 12-14 (Tm-Lu) of the tetraiminodiphenolate macrocycle L2- have been prepared by the transmetallation reaction between [Pb(LH2)(NO3)2] and Ln(NO3)3.nH2O. In these compounds, the uncoordinated imino nitrogens are protonated an…
The structure of a TiAl3Hx complex for the formation of a TiAl3 binary phase that could play important roles in the reversible de-/hydrogenation of Ti-doped NaAlH4 has been identified on the basis of first principles density functional theory studies.
This review focuses on fiber analysis methods, where the fibers are carried in suspension. They are photographed in a flow cell and their properties are evaluated by digital image analysis. Three fields of fiber analysis are covered: Fiber morphology, pulp surface chemistry, and chemically induced swelling respectivel…
