High molecular weight thiophene-containing conjugated polymers were successfully synthesized by Suzuki polycondensation of aryl dibromides and 2,5-thiophenebis(boronic acid) derivatives by using a new thiophene-containing bulky phosphorous compound as the ligand for a zerovalent palladium catalyst.
This paper proposes a method for the generation of high-contrast localized sinusoidal fringes with spatially noncoherent illumination and relatively high light throughput. The method, somehow similar to the classical Lau effect, is based on the use of a Fresnel biprism. It has some advantages over previous methods for…
Alterations in the electronic structure of adsorbed zinc(II) etioporphyrin I (ZnEtio) through interaction with bridging oxygen vacancies on TiO(2)(110) are studied by scanning tunneling microscopy and spectroscopy at cryogenic temperatures under ultrahigh vacuum (UHV) conditions. Upon lateral manipulation of ZnEtio mo…
The potential of Mössbauer spectroscopy to study the biodegradation process of magnetic nanoparticles in vivo was demonstrated. Magnetic nanoparticles in form of ferrofluid were administrated to mice. The Mössbauer study of the mice liver samples has shown that in addition to the sextet of lines related to the injecte…
This paper deals with making a bird dummy for testing the bird-strike resistance of aircraft components. A new bird dummy has been offered. It differs from existing analogs by reproducing the impact impulse with high accuracy. Besides, it is easy to make, store, and clean up its fragments after tests. The bird dummy i…
As dry adhesives resembling the gecko lizard's dry adhesion, double-level nanopillars of extremely high aspect-ratio (27.5–225) are fabricated from a rigid low-surface energy fluoropolymer (Teflon AF) by a replica-molding method. Upon infiltration of Teflon AF melt into anodic aluminium oxide nanopores as the mold, th…
Abstract Electrorheological (ER) and magnetorheological (MR) fluids based on electro‐ and magneto‐responsive particles, respectively, are smart suspensions with the ability to undergo phase transitions from a liquid‐like to a solid‐like state as a result of stimuli of an electric or magnetic field. The application of…
The solubilities and densities of solid–liquid equilibria in the quaternary system KCl–KBr–K 2 SO 4 –H 2 O at 348 K were determined experimentally by using an isothermal solution saturation method. According to the experimental data, the phase diagram of the quaternary system was plotted. In the equilibrium phase diag…
In this work, we present the first experimental evidence of negative dielectric susceptibility in a two-dimensional silicon photonic crystal (PhC) with negative refractive index behavior. In the frequency range in which the effective refractive index neff is equal to −1, the incident light couples efficiently to the g…
This manuscript describes a series of mesogen-jacketed liquid crystalline polymers (MJLCPs) and elastomers (MJLCEs) bearing a novel polynorbornene backbone, onto which the liquid crystalline mesogen is laterally attached by a single covalent bond without spacers. The side-on mesogenic monomers are synthesized via pall…
This paper presents the design and evaluation of magnetoelastic sensors intended for wireless monitoring of tissue accumulation in peripheral artery stents. The sensors are fabricated from 28 µm thick foils of magnetoelastic 2826MB Metglas™, an amorphous Ni–Fe alloy. The sensor layer consists of a frame and an active…
In this paper, a novel nanohole array with three-dimensional structure was generated by colloidal lithography existing of a free-standing nanohole array that experiences the same environment on both sides in 3D space. In a practicable way, the nanoholes were lifted up from the substrates, resulting in undulate morphol…
A facile 2-dimensional coupling of AgBr nanosheets with graphene oxide (GO) sheet has been developed to fabricate an efficient dual-functional visible-light-responsive GO@AgBr nanophotocatalyst. Compared to bare AgBr nanosheets, the as-obtained GO@AgBr nanocomposite exhibits enhanced photocatalytic activity towards de…
Abstract Carbon molecular sieve (CMS) membranes offer advantages over traditional polymeric membrane materials, but scale‐up of manufacturing systems has not received much attention. In the recent decade, there has been a dramatic increase in fundamental research on these materials with a variety of applications being…
In the current study, the effect of the thickness and the foam density in three-dimensional integrated woven sandwich composites on quasi-static properties was investigated. For this purpose, produced samples were subjected to uniaxial flatwise compression tests and their compression strength and moduli were determine…
In this Communication, we report the synthesis and characterization of novel Hofmann-like spin-crossover porous coordination polymers of composition {Fe(L)[M(CN)(4)]}·G [L = 1,4-bis(4-pyridylethynyl)benzene and M(II) = Ni, Pd, and Pt]. The spin-crossover properties of the framework are closely related to the number an…
We report a novel strategy to synthesize nanostructured magnetoceramics via a direct bulk pyrolysis of hyperbranched polycarbosilanes without any assistance of nanoscaled templates. The hyperbranched polyferrocenyl(boro)carbosilanes (hb-PBCS) were synthesized via a convenient A2+B3 strategy. After the pyrolysis of hb-…
Silver nanowires (NWs) are currently fabricated via template-free or template-assisted methods. The former is based on a medium-mediated anisotropic synthesis, which enables precursor atoms to be selectively adsorbed onto specific crystallographic planes, and the latter is performed via directional growth guided by pr…
Metallosphaera sedula is an extremely thermoacidophilic archaeon that grows heterotrophically on peptides and chemolithoautotrophically on hydrogen, sulfur, or reduced metals as energy sources. During autotrophic growth, carbon dioxide is incorporated into cellular carbon via the 3-hydroxypropionate/4-hydroxybutyrate…
Complexes of Cu(II), Ni(II) and Zn(II) have been prepared with bis(thiosemicarbazonate) ligands bearing a pendant Bodipy fluorophore both with (ATSMBodipy) and without (GTSBodipy) backbone methyl groups. Biophysical analysis using steady state confocal laser scanning fluorescence images and excited state fluorescence…
