<em>Angewandte Chemie International Edition</em> is one of the prime chemistry journals in the world, publishing research articles, highlights, communications and reviews across all areas of chemistry.
The electronic properties of $\mathrm{La}\mathrm{Co}{\mathrm{O}}_{3}$ across the spin-state transition are studied using the $\mathrm{LDA}+\mathrm{DMFT}$ method. Combining the local density approximation band structure of the $\mathrm{Co}\phantom{\rule{0.2em}{0ex}}3d$ orbitals in the low-spin state with multiorbital d…
This paper systematically investigated the self-assembly of a cylinder-forming A13B3C2 triblock terpolymer confined in cylindrical nanopores using an annealing Monte Carlo simulation. When the pore wall is absolutely neutral, we observed the helix structures alternating with partial cylinder structures at the outside…
Abstract Polyaniline was synthesized in the presence of lignosulfonic acid to yield a product (LIGNO‐PANI) that is water‐dispersible. Several samples ranging from 0 to 70% lignosulfonate (LS) were prepared. These samples were then evaluated for differences in dispersibility and conductivity. As the percent of LS in th…
The feasibility of using converter basic slag (CBS) as a source of Mg for gypsum‐amended acidic soils was studied in a Plinthic Palexerult from western Spain. An experimental farm was established and the Ap horizon of the soil was amended with limestone (L), phosphogypsum (PG), or red gypsum (RG) to alleviate Al toxic…
Abstract The objective of this study is the thermoreversible crosslinking of maleated ethylene/propylene copolymer (MAn‐ g ‐EPM) using the equilibrium reaction with diols. Covalent hemi‐ester crosslinks are formed via the reaction of anhydrides with alcohols, while an equilibrium shift at elevated temperatures may res…
Chemical reactivity may be significantly altered when reagents are confined to move within a nanoscale environment. Chemical reactions inside carbon nanotubes (CNTs), in particular, have been the focus of some attention. To help lay theoretical foundations for understanding such nanoscale-confined chemistry, we study…
We have studied the nature of structural transitions in B 2 O 3 glass under pressure using molecular dynamics simulations, based on a newly developed coordination-dependent charge transfer potential, to complement the results from our earlier Brillouin and Raman scattering experiments and to interpret these findings.…
The adsorption and diffusion of atomic nitrogen on Rh{211} as well as formation and desorption of molecular nitrogen from this surface have been investigated by means of density functional theory (DFT) calculations. The elementary step reaction mechanism derived from this comprehensive DFT study forms the foundation o…
The interparticle force between two colloidal particles in a nematic liquid crystal is directly measured as a function of the interparticle distance R by two different experimental methods: the free-release method and the optical tweezing method. The obtained force between an elastic 'dipole', which constitutes a coll…
Abstract The in situ polymerization of the anilinium‐intercalated synthetic mica clay can easily result in an intercalated polyaniline (PANI)/clay nanocomposite. The FT‐IR spectra demonstrated a significant shift for ν (CN) at 1292 cm −1 of the templated polymerized and intercalated PANI molecules. A red shift of λ m…
Amino end-terminated poly( l -lactic acid), poly(trimethylene carbonate), and polycaprolactone were synthesized via ring-opening polymerization techniques. The amino terminus was used to form a covalent link to poly(dichlorophosphazene), itself synthesized using a living cationic polymerization. The chlorine atoms in…
The synthesis and characterization of several formazans containing strong electron-withdrawing substituents (cyano and nitro) in the 3 position of the ligand backbone are described. Reactions of aryldiazonium cations with the conjugated bases of either cyanoacetic acid or nitromethane lead to 1,5-diaryl-3-cyano- or 3-…
In this work, Mg x Zn 1− x O (MZO) thin films were grown on quartz by rf magnetron sputtering technology. It was found that MZO films possess preferred c -axis orientation and exhibit hexagonal wurtzite structure up to a Mg composition of 44.26 mol%. Furthermore, the band gap determined by absorption spectra was small…
In this paper, we report the preparation and characterization of fluorophore-free luminescent organosilica nanoparticles (NPs) with sizes varying from 50 to 250 nm. These NPs were synthesized by the Stöber method by incorporating several organosilanes together with the silicate precursor (tetraethyl orthosilicate, TEO…
The two initial stages of spinodal decomposition of a symmetric binary Lennard-Jones fluid have been simulated by molecular dynamics simulations, using a hydrodynamics-conserving thermostat. By analyzing the growth of the average domain size R(t) with time, a satisfactory agreement is found with the R(t) proportional…
We present a mean-field theory to describe phase separations in mixtures of a nematic liquid crystal and a colloidal particle. The theory takes into account an orientational ordering of liquid crystals and a crystalline ordering of colloidal particles. We calculate phase diagrams on the temperature-concentration plane…
Abstract Multi‐walled carbon nanotube/polypropylene composites (PPCNs) were prepared by melt compounding. The linear viscoelastic properties, nonisothermal crystallization behavior, and kinetics of PPCNs were, respectively, investigated by the parallel plate rheometer, differential scanning calorimeter (DSC), X‐ray di…
The scaling analysis of phase-change memory (PCM) cells is an essential step toward validation as a competitive technology in terms of array density and current consumption. While the current scaling has been addressed in a companion paper, we focus here on the thermal crosstalk, namely, the temperature increase in 1…
A highly efficient direct electrodeposition method was used to prepare Co−Cu alloy nanotubes in an anodic alumina template without modification. The morphology and structure of as-prepared Co−Cu nanotubes were examined by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The format…
