Ruthenium (Ru)-modified (up to 1 wt %) tungsten trioxide (WO 3 ) samples were synthesized and characterized by X-ray diffraction, X-ray photoelectron spectroscopy (XPS), scanning and transmission electron microscopy, and Raman spectroscopy. Ru was found to form hexagonal clusters on {111} planes of the underlying WO 3…
Pulsed excitation of broad spectra requires very high field strengths if monochromatic pulses are used. If the corresponding high power is not available or not desirable, the pulses can be replaced by suitable low-power pulses that distribute the power over a wider bandwidth. As a simple case, we use microwave pulses…
Chiral symmetry, fundamental in the physics of graphene, guarantees the existence of topologically stable doubled Dirac cones and anomalous behaviors of the zero-energy Landau level in magnetic fields. Its crucial role, especially its manifestation in optical responses and many-body physics in graphene, is explained i…
Conducting polymer/protein composites, P(EDOT-LZ), of poly(3,4-ethylenedioxythiophene) (PEDOT) and lysozyme, a protein with bactericidal activity, have been prepared by in situ anodic polymerization. The stability of the composite obtained from a polymerization medium consisting of an acetonitrile:water solution (1:4…
We present atomic-scale imaging of oxygen columns and show quantitative analysis on the occupancy of the columns in yttria-stabilized zirconia (YSZ) using aberration-corrected TEM operated under the negative Cs condition. Also, individual contributions both from oxygen column occupancy and the static displacement of o…
The influence of low-consistency refining on the surface chemical and morphological properties of softwood chemical pulp was investigated using a special laboratory refining station and advanced topochemical analyses. Refined pulp was fractionated in order to investigate the refining effect on fibres separately, witho…
We present a canonical quantization of macroscopic electrodynamics. The results apply to inhomogeneous media with a broad class of linear magnetoelectric responses, which are consistent with the Kramers-Kronig and Onsager relations. Through its ability to accommodate strong dispersion and loss, our theory provides a r…
This study aims to assess the efficacy and safety of Rehmannia glutinosa acteosides used in combination with the angiotensin receptor blocker irbesartan to treat primary chronic glomerulonephritis. A total of 479 patients diagnosed with primary chronic glomerulonephritis were recruited from outpatient clinics and were…
There are large number of proteins, the existence of which are known but not their crystal structure, because of difficulty in finding the exact condition for their crystallization. Heterogeneous nucleation on disordered porous substrates with small yet large distribution of pores is considered a panacea for this prob…
Treatment of the (AuC2R)n acetylides with phosphine ligand 1,4-bis(diphenylphosphino)butane (PbuP) and Ag(+) ions results in self-assembly of the heterobimetallic clusters of three structural types depending on the nature of the alkynyl group. The hexadecanuclear complex [Au12Ag4(C2R)12(PbuP)6](4+) (1) is formed for R…
BACKGROUND: Previous study showed that hydroxyapatite nanoparticles (nano-HAPs) inhibited glioma growth in vitro and in vivo; and in a drug combination, they could reduce adverse reactions. We investigated the possible enhancement of radiosensitivity induced by nano-HAPs. METHODS: In vitro radiosensitization of nano-H…
Sodium carboxymethyl cellulose/poly(acrylamide-co-2-acrylamido-2-methylpropane sulfonic acid) semi-interpenetrating polymer network (semi-IPN) hydrogels were prepared by using free radical polymerization technique. Silver nanoparticles were formed by reduction of silver nitrate in semi-IPN hydrogels with sodium borohy…
We introduce the concept of parity symmetry in restricted spatial domains---local parity---and explore its impact on the stationary transport properties of generic, one-dimensional aperiodic potentials of compact support. It is shown that, in each domain of local parity symmetry of the potential, there exists an invar…
The stress and loading rate on disks of SrAl2O4:Eu mixed epoxy resin were measured by a lifetime-based method. The concentration of the mechanoluminescence (ML) phosphor and the excitation power did not affect the measured lifetime. The lifetime was proportional to the stress and was inversely proportional to the load…
The spherical micelle and vesicle composed of [PW12O40](3-) and poly(styrene-b-4-vinylpyridinium methyl iodide) are regarded as a model system to study spherical polymer brushes (SPBs) in solvents of various quality. The pure repulsions occur for the brush chains in the chloroform solution and chloroform/methanol mixt…
Abstract ZnO nanostructures with various morphologies including rod‐like, sheet‐like, needle‐like and flower‐like structures were successfully synthesized via a fast and facile microwave‐assisted hydrothermal process. Reaction temperature, reaction time and the addition of NaOH were adjusted to obtain ZnO with differe…
We consider anisotropic Allen–Cahn equations with interfacial energy induced by an anisotropic surface energy density γ. Assuming that γ is positive, positively homogeneous of degree 1, strictly convex in tangential directions to the unit sphere and sufficiently smooth, we show the stability of various time discretiza…
Abstract Two series of unsymetrically functionalized, carboxyethynylphenyl‐containing porphyrins, bearing either 2,4,6‐triisopropylphenyl or triphenylamino substituents at three of the four meso positions, have been prepared by Sonogashira coupling from the corresponding ethynyl‐ or iodo‐functionalized porphyrin precu…
So what is the "big deal" about engineering of collagen materials? It is certainly not enough to produce the familiar line about it being "more physiological." This phrase explains very little of the substance and gets nowhere near to the base of the question. We need to be clear about why this is important enough to…
In this work we propose a multidimensional free energy perturbation scheme that allows the evaluation of the free energy difference between a state sampled based on importance sampling and almost any state that can be constructed by the reduction of the number of molecules in the system and the change of either the in…
