Domain structures as typically found in tetragonally polarized ferroelectrics are investigated regarding their large-signal behavior by conducting phase-field simulations. The underlying free energy function of the phase-field model stems from a completely knowledge-based multiscale adjustment approach (Volker et al 2…
In this paper we discuss the elaboration, optical properties and possible applications of thin films and nano-patterns of molecular spin crossover complexes. These bistable nanostructures can respond reversibly with fast response times to various external stimuli, such as temperature changes, application of an externa…
A series of alternating block polyurethanes (abbreviated as PU3/4HB-alt-PEG) and random block polyurethanes (abbreviated as PU3/4HB-ran-PEG) based on biodegradable polyester poly(3-hydroxybutyrate-co-4-hydroxybutrate) (P3/4HB-diol) and poly(ethylene glycol) (PEG) with similar chemical compositions were synthesized usi…
Abstract A magnetic microrheometer is used to characterize the development of viscosity at different depths in UV‐cured epoxy coatings. Lateral magnetic particle velocities are tracked at different depths to quantify viscosity gradients. In general, viscosity build‐up is faster near the coating surface, tending to pro…
We report the draft genome sequence of Halomonas sp. strain KM-1, which was isolated in Ikeda City, Osaka, Japan, and which produces the bioplastic poly(3-hydroxybutyrate). The total length of the assembled genome is 4,992,811 bp, and 4,220 coding sequences were predicted within the genome. Genes encoding proteins tha…
Poly(2-aminobenzothiazole)s were synthesized by electropolymerization method using 2-aminobenzothiazole (2ABT) and 6-ethoxy-2-aminobenzothiazole (EtO-2ABT) as the monomers. Cyclic voltammetry (CV) was used to determine the electrochemical oxidation–reduction characteristics. Electrochemical deposition of the polymers…
Oxidation of 3,4-ethylenedithio-3'-iodo-tetrathiafulvalene (EDT-TTF-I) and 3,4-ethylenedithio-3',4'-diiodo-tetrathiafulvalene (EDT-TTF-I2) with DDQ afforded two different salts formulated as (EDT-TTF-I)(DDQ) and (EDT-TTF-I2)2(DDQ)·(CH3CN), both characterized with a full charge transfer to the DDQ acceptor moiety and b…
The condensation reaction of (4-(6,7-dimethyldithio-tetrathiafulvalene)-aniline) with 2,6-diformylpyridine afforded an electroactive Schiff base (N,N,N) pincer (3). This pincer was reacted with Zn(II) cation to yield the corresponding Zinc chloride complex (4). The crystal structure of the newly prepared electroactive…
Abstract An interpenetrating polymer network (IPN) material with controllable nanoporosity is developed for applications such as chemical protection. The IPN material is based on a conducting polymer backbone consisting of thiophene and 3,4 ethylenedioxythiophene (EDOT) repeat units–poly(thiophene‐EDOT)–formed within…
Silk films are promising protein-based biomaterials that can be fabricated with high fidelity and economically within a research laboratory environment (1,2). These materials are desirable because they possess highly controllable dimensional and material characteristics, are biocompatible and promote cell adhesion, ca…
We derive the instantaneous densities of electric energy and electric power dissipation in lossless and lossy dispersive media for a time-harmonic electric field. The instantaneous quantities are decomposed into DC and AC components, some of which are shown to be independent of the dispersion of dielectric constants.…
The aim of this study was to experimentally determine the bending behavior of developed multilayered multistitched E-Glass preform structures. For this reason, a bending rigidity test instrument based on the cantilever test principle was used. A bending rigidity test was conducted on all developed multilayered multist…
The catalytic efficiency of takovite-aluminosilicate-chromium catalysts obtained by adsorption of Cr(3+) ions from aqueous solutions by a takovite-aluminosilicate nanocomposite adsorbent is reported. The adsorbent was synthesized by the coprecipitation method. The catalytic activity of the final Cr-catalysts depended…
A new megastigmane glycoside, grasshopper ketone 3-O-primveroside (1), was isolated from the methanolic extract of the whole herbs of Sinocrassula indica (Crassulaceae). Its structure was elucidated on the basis of spectral and chemical evidence.
Relatively little is known regarding the interaction of nanoscale objects with dynamic complex biological systems. Microarray-based toxicogenomics studies may serve as a suitable technique to explore the genome wide effects of nanoparticles on any organism through a single experiment. The influence of nanoporous alumi…
Photoelectron emission from the valence band of a metal surface due to the grazing incidence of ultrashort laser pulses is studied in the framework of a distorted-wave formulation. We propose a model, named the band-structure-based--Volkov (BSB-V) approximation, which takes into account the contribution of the band st…
The pyrazolate-based ditopic ligand HL forms a strongly hydrogen-bonded corner complex dimer [Fe(II)(HL)(2)](2)(BF(4))(4) (1) with a [2 × 2] gridlike arrangement of four ligand strands. The two empty vertices can then be filled with {Ag(2)}(2+) dumbbells, yielding the unprecedented diferric complex [L(4)Fe(III)(2)(Ag(…
The reaction of the croconate dianion (C(5)O(5))(2-) with a Fe(III) salt has led, unexpectedly, to the formation of the first example of a discrete Fe(II)-croconate complex without additional coligands, K(4)[Fe(C(5)O(5))(2)(H(2)O)(2)](HC(5)O(5))(2)·4H(2)O (1). 1 crystallizes in the monoclinic P2(1)/c space group and p…
Total x-ray scattering measurements of spider dragline silk fibers from Nephila clavipes, Argiope aurantia, and Latrodectus hesperus all yield similar structure factors, with only small variations between the different species. Wide-angle x-ray scattering from fibers orientated perpendicular to the beam shows a high d…
Fluorescence imaging technique has been used for imaging of biological cells and tissues in vivo. The Cd-free luminescent quantum dots conjugating with a cancer targeting ligand has been taken as a promising biocompatibility and low cytotoxicity system for targeted cancer imaging. This work reports the synthesis of fl…
