The ordered ultrathin film based on iron(III) porphyrin and Co–Al layered double hydroxide (Co–Al LDH) nanosheets has been fabricated via the layer-by-layer (LBL) method. The film modified electrode demonstrates a couple of well-defined reversible redox peaks attributed to Co(III)/Co(II), with iron(III) porphyrin serv…
The role of solitons in transport, dielectric, and magnetic properties has been revealed for the quasi-one-dimensional organic charge-transfer salt, TTF-QBrCl3 [tetrathiafulvalene (TTF)-2-bromo-3,5,6-trichloro-p-benzoquinone (QBrCl3)]. The material was found to be ferroelectric and hence the solitons should be located…
Abstract Low‐temperature De‐NO x technology is a new topic in the area of flue gas treatment. This paper presents experimental studies on selective catalytic reduction (SCR) of NO x from synthetic flue gas over iron‐based catalysts with ammonia in a fluidized reactor. The iron‐based catalysts used in the experiments a…
Here, we demonstrate the use of X-ray absorption edge spectroscopy in conjunction with high resolution X-ray nano-computed tomography to provide a comprehensive microstructural map of a Ni–YSZ electrode from a Solid Oxide Fuel Cell. The experimentally derived microstructure has been used to develop a geometrical test…
Ein hübsches Pärchen: Die paramagnetischen CuII-Ionen zweier Kupfer-Salen-Metallbasenpaare in benachbarten Positionen in eine DNA-Doppelhelix (siehe Bild) sind antiferromagnetisch gekoppelt, und die Austauschkopplungskonstante ist −2J=22.4 cm−1. Die dipolare Kopplungskonstante ergab einen Cu⋅⋅⋅Cu-Abstand von 3.7 Å, de…
We present results of angle-dependent magnetoresistance measurements and direct optical images of underdoped $\text{Ba}{({\text{Fe}}_{1\ensuremath{-}x}{\text{Co}}_{x})}_{2}{\text{As}}_{2}$ which reveal partial detwinning by action of a 14 T magnetic field. The relative change in the twin domain population for the give…
We present a ReaxFF reactive forcefield designed to reproduce first-principles density-functional theory (DFT) calculations on gold bulk structures, surfaces, and nanoparticles. We compare the ReaxFF results with those obtained from other atomistic potentials along with results from Perdew-Burke-Ernzerhof--generalized…
The solubilities of quercetin in water + methanol and water + ethanol mixtures were measured over the temperature range of (292.8 to 333.8) K. The concentrations of quercetin in different solvent mixtures were analyzed by the UV/vis spectrophotometric method. The experimental solubility data were correlated with the m…
Gold-supported ceria and europium-doped ceria catalysts were prepared by the deposition−precipitation method. The influence of the pretreatment atmosphere and temperature on the concentration of oxygen vacancies and gold dispersion on the Au/CeEu(10) catalyst under actual reaction conditions was investigated by “in si…
This paper presents a simulation study of the applicability of the Rosenfeld entropy scaling to the systems which cannot be approximated by the effective hard spheres. Three systems are studied: the Herzian spheres, the Gauss core model, and a soft repulsive shoulder potential. These systems demonstrate diffusion anom…
Abstract This review presents the state of the art regarding the improvement of scratch resistance of polymeric coatings. In particular, our attention is focused on the effect of inorganic nanometric fillers on the scratch resistance of organic coatings. Two main strategies are described for the achievement of such na…
The superatom model for nanoparticle structure is shown to be inadequate for the prediction of the thermodynamic stability of gold nanoparticles. The observed large HOMO-LUMO gaps for stable nanoparticles predicted by this model are, for sulfur-stabilized gold nanoparticles, attributed to covalent interactions of the…
We systematically investigated the variation in transition behavior and physical properties over a wide excess Ni (acting as defect) concentration range $(x=0--2.5)$ in ${\text{Ti}}_{50\ensuremath{-}x}{\text{Ni}}_{50+x}$ alloys. This enables the establishment of an updated quantitative phase diagram for this important…
This article reviews the applications of silicone resins as ceramic precursors. The historical background of silicone synthesis chemistry is introduced to explain the production costs and supply availability of various silicones. Thermal degradation processes of silicones are classified in terms of the main chain stru…
The adsorption of NO 2, NO, and atomic N and O on the clean ZnO(101̅0) surface is examined using density functional theory and ab initio molecular dynamics simulations. Adsorption of NO 2 is also investigated on a defect surface containing an O vacancy. Calculated binding energy values, Bader charges, vibrational freq…
The orbital magnetic susceptibility of a gas of noninteracting massless Dirac fermions is zero when the Fermi energy is away from the Dirac point. Making use of diagrammatic perturbation theory, we calculate exactly the orbital magnetic susceptibility of massless Dirac fermions to first order in the Coulomb interactio…
Because of its versatility, the layer-by-layer (LBL) assembly method has become a popular tool for preparing multimaterial films, yet astonishingly little is known about the fundamental rules governing their deposition. Here we show an unusual case of self-patterning LBL films made from poly(allylamine hydrochloride)…
Polymeric micelles are used as pharmaceutical carriers to increase solubility and bioavailability of poorly water-soluble drugs. Different ligands are used to prepare targeted polymeric micelles. Earlier, we developed the method for use of specific landscape phage fusion coat proteins as targeted delivery ligands and…
The development of nanotechnologies may lead to environmental release of nanomaterials that are potentially harmful to human health. Among the nanomaterials, multiwalled carbon nanotubes (MWCNTs) are already commercialized in various products which can be in direct contact with populations. However, few studies addres…
CO-catcher: Carbon monoxide can be detected selectively and sensitively by the binuclear rhodium complex cis-[Rh2(C6H4PPh2)2(O2CCH3)2](HO2CCH3)2. This complex, which contains two cyclometalated phosphine ligands, coordinates CO axially and undergoes a color change from violet to orange-yellow (see picture).
