A new chiral sulfide family, Ln(4)InSbS(9) (Ln = La, Pr, Nd), with its own structure type in space group P4(1)2(1)2 or its enantiomorph P4(3)2(1)2 has been synthesized by solid-state reaction. Remarkably, the La member shows the strongest Kleinman-forbidden second harmonic generation to date, with an intensity 1.5 tim…
Until now, the results of nanotoxicology research have shown that the interactions between nanoparticles (NPs) and cells are remarkably complex. In order to get a deep understanding of the NP-cell interactions, scientists have focused on the physicochemical effects. However, there are still considerable debates about…
The human heart cannot regenerate after an injury. Lost cardiomyocytes are replaced by scar tissue resulting in reduced cardiac function causing high morbidity and mortality. One possible solution to this problem is cardiac tissue engineering. Here, we have investigated the suitability of non-mulberry silk protein fib…
Two-dimensional (2D) atomic crystals, especially graphene, have received much attention. However, the main shortcoming of graphene is its zero band gap. Silicon carbide, composed of silicon and carbon, is a typical wurtzite compound semiconductor, with more than 250 alloy types. Herein, we give some evidence of the so…
We present the design, numerical simulations and experimental measurements of terahertz metamaterial absorbers with a broad and flat absorption top over a wide incidence angle range for either transverse electric or transverse magnetic polarization depending on the incident direction. The metamaterial absorber unit ce…
The double manganite CaCu${}_{3}$Mn${}_{4}$O${}_{12}$ doped with ${}^{119}$Sn atoms (\ensuremath{\sim}1 at.$%$ with respect to manganese atoms) was studied by use of M\"ossbauer spectroscopy. Formally tetravalent Sn${}^{4+}$ ions substitute for isovalent manganese ions in the octahedral (Mn${}^{4+}$O${}_{6}$) polyhedr…
The solubilities of sodium 4-nitrobenzenesulfonate in binary sodium chloride + water, sodium sulfate + water, and ethanol + water solvent mixtures were measured with temperatures ranging from (273.15 to 323.15) K by a steady-state method. Results of these measurements were correlated by a modified Apelblat equation. S…
We have recently reported that a red-emitting iridium complex (btp)<sub>2</sub> Ir (acac) (BTP) serves as a hypoxia-sensing probe for tumor imaging in living mice. BTP exhibits oxygen-sensitive phosphorescence that can be utilized to monitor oxygen levels in living cells and to visualize hypoxic tissues. To improve th…
The aim of this paper is to obtain an epoxy resin with best properties such as good cure of polymer (by using DSC and TGA). The thermal stability and kinetic parameters of epoxy resin RTM6 using non-isothermal thermogravimetry/derivative thermogravimetry (TG/DTG) analysis with a series of different ratios of TiO2-PC50…
In high-voltage capacitor bushings, there is maximum field intensity at the edge of the aluminum foil and where foils overlap. Any technique decreasing much field intensity in those regions will significantly optimize the bushings’ electrostatic characteristics. This paper presents the study of the effect of edge dive…
Based on the solubilities of pimelic acid in ether or tetrahydrofuran or ethanol or methanol, the experimental data were correlated and compared with Apelblat equation, simplified Apelblat equation and λ h equation, respectively. The results showed that the simplified Apelblat equation had better agreement with experi…
Eukaryotic-like serine/threonine protein kinases (ESTPKs) are widely spread throughout the bacterial genomes. These enzymes can be potential targets of new antibacterial drugs useful for the treatment of socially important diseases such as tuberculosis. In this study, ESTPKs of pathogenic, probiotic, and antibiotic-pr…
Using the single and double excitation coupled cluster level of theory (CCSD) and the density functional theory/Becke 3-parameter Lee-Yang and Parr (DFT/B3LYP) methods, we test the performance of the Pol, ZPol, and LPol-n (n = ds, dl, fs, fl) basis sets in the accurate description of the intensity dependence of the re…
The results of quantum-chemical analysis of elastic and strength properties of the bamboo-like tube are presented in this paper. For the first time the configuration of the thinnest stable bamboo-like tube was established. The bamboo-like nanotube breaking point is established to be under compression of 11GPa. Configu…
Several nonwovens were studied to explore the relationship between their structural characteristics, permeability and acoustic absorbing behavior. Fundamental structural parameters including thickness, gram square meter and porosity were considered. Results show that the permeability is not just linear to porosity, bu…
Bubble electrospinning is a novel method to produce ultrafine nanofibers. In this work, a mathematical model of the electric field distribution in a critical state was established for bubble electrospinning process and was numerically simulated using finite element method. The results indicated that the maximum electr…
The molecular and electronic structures, stabilities, bonding features, magnetotropicity and absorption spectra of benzene-trinuclear Cu(I) and Ag(I) trihalide columnar binary stacks with the general formula [c-M(3)(μ(2)-X)(3)](n)(C(6)H(6))(m) (M = Cu, Ag; X = halide; n, m ≤ 2) have been investigated by means of elect…
Abstract The shells of most anomalodesmatan bivalves are composed of an outer aragonitic layer of either granular or columnar prismatic microstructure, and an inner layer of nacre. The T hraciidae is one of the few anomalodesmatan families whose members lack nacreous layers. In particular, shells of members of the gen…
We report here temperature-dependent x-ray structural and Raman spectroscopy data, on the ferromagnetic double-perovskite (Bi0.9La0.1)2NiMnO6 epitaxial thin films. Results indicate a ferroelectric transition occurring at about 450 °C. Low-temperature polarization loops allow to clearly observing polarization switching…
In this work, thia and selenocarbocyanines with n-alkyl chains of different length, namely with methyl, ethyl, propyl, hexyl and decyl substituents, were studied in homogeneous and heterogeneous media for comparison purposes. For both carbocyanine dyes adsorbed onto microcrystalline cellulose, a remarkable increase in…
