Abstract Growth kinetics of zinc (tris) thiourea sulphate (ZTS) crystals investigated as a function of supersaturation is reported in this communication. Crystal growth rates were investigated normal to the (100), (010) and (001) faces under growth conditions employed for bulk crystal growth. The growth rates normal t…
Abstract We prepared a square cyclic porphyrin dodecamer via the tetramerization of a trimer shaped like a right angle. The molecule was visualized by scanning tunneling microscopy to be square.
Single‐crystal Sb 2 S 3 nanotubes with chain‐like structures (see Figure) have been successfully synthesized by chemical vapor transport using sulfur as the transport agent. Detailed characterization of the nanotubes shows the growth direction of Sb 2 S 3 nanotubes is determined by the crystallographic orientation of…
Abstract The whole controlled synthesis of novel amphiphilic polylactide (PLA)‐grafted dextran copolymers was achieved. The control of the architecture of such biodegradable and potentially biocompatible copolymers has required a three‐step synthesis based on the “grafting from” concept. The first step consisted of th…
The thermal conductivity of molten sodium chloride and potassium chloride has been computed through equilibrium molecular dynamics Green-Kubo simulations in the microcanonical ensemble (N,V,E). In order to access the temperature dependence of the thermal conductivity coefficient of these materials, the simulations wer…
We have investigated the electrolyte-induced collapse of a polyelectrolyte brush covalently attached to a planar solid surface. Positively charged poly-4-vinyl [N-methyl-pyridinium] (MePVP) brushes were prepared in situ at the surface by free radical chain polymerization using a surface-immobilized initiator monolayer…
Abstract Tris (thiourea) zinc sulphate (ZTS), a semiorganic nonlinear optical (NLO) material has been synthesized at 30 °C. The solubility was determined in different solvents such as water, ethanol and water mixture of ethanol (1:1). Good quality single crystals with size 10 × 8 × 6 mm 3 were grown by slow evaporatio…
Reports about the ferroelectric ordering temperatures in the multiferroic hexagonal $R{\mathrm{MnO}}_{3}$ system are controversial: transition temperatures varying between $\ensuremath{\approx}900\mathrm{K}$ and $\ensuremath{\approx}1300\mathrm{K}$ are reported for the same material. To elucidate the structural change…
Lead island films were obtained via vacuum vapor deposition on glass and ceramic substrates at 80 K. Electrical conductance was measured during vapor condensation and further annealing of the film up to room temperature. The resistance behavior during film formation and atomic force microscopy of annealed films were u…
As more and more structures of macromolecular complexes get solved in different conditions, it has become apparent that flexibility is an inherent part of their biological function. Normal mode analysis using simplified models of proteins such as the elastic network model has proved very effective in showing that many…
In this Communication we report about the unexpected effect of ruthenium doping in sodium ligthly-doped manganites. This effect seems to be in contrast with the usual model applied to describe the effect of this magnetic ion into the manganite structure. We propose a possible compensation mechanism which seems also ab…
In this communication the enhancement of low temperature magnetoresistance in polycrystalline La1-xCaxMnO3 manganites is discussed. It is shown that so-called grain boundary effects seem to be the simplest and natural explanation of this phenomenon.
This study evaluates the feasibility of a new class of partially restrained connections using shape memory alloys. In the martensitic form, shape memory alloys (SMAs) have the ability to recover large residual deformations by heating the alloy above its transformation temperature. The proposed connection consists of f…
Abstract In this review, the recent achievements in the synthesis of inorganic nanomaterials inside the spatially confined volume of individual micro‐ and submicroreactors (emulsions, micelles, organized thin films, polyelectrolyte capsules, etc.) are presented. The advantages and shortcomings of each type of microrea…
The behavior of carbon and nitrogen atoms in iron based solid solution is studied by ab initio density-functional-theory calculations. The interaction of a C or a N atom in $\ensuremath{\alpha}$-Fe with a vacancy, other C or N interstitials as well as self-interstitial atoms is discussed and compared to known experime…
Systematic experimental data on resonant inelastic X-ray scattering (RIXS) in GaN near the N K-edge are presented for the first time. Excitation energy dependence of the spectral structures manifests the band structure effects originating from momentum selectivity of the RIXS process. This finding allows obtaining k-r…
Superconducting thin films of magnesium diboride (MgB$_2$) were prepared on MgO (001) substrate by a molecular beam epitaxy (MBE) method with the co-evaporation conditions of low deposition rate in ultra-high vacuum. The structural and physical properties of the films were studied by RHEED, XRD, XPS, resistivity and m…
Electronic and structural properties of ultrathin MgO layers grown on epitaxial Fe(110) films were investigated at room temperature by means of spin-resolved photoelectron spectroscopy, Auger-electron spectroscopy, and low energy electron diffraction. The spin polarization at the Fermi level of the Fe(110) film decrea…
The title compound, [Zn(C44H28N4)(C2H6OS)]·0.79C2H6OS·0.21CHCl3, crystallizes as a sulfoxide–chloroform true clathrate. The main residue, (dimethyl sulfoxide)(tetraphenylporphyrinato)zinc(II), is a five-coordinate zinc–porphyrin complex, with dimethyl sulfoxide as an axial ligand. The crystal structure is charac…
