Potassium dimanganese trivanadate, KMn2V3O10, was synthesized hydrothermally and its crystal structure was determined from single-crystal X-ray diffraction data. The novel phase crystallizes with triclinic symmetry in space group P\bar 1 with unit-cell parameters of a = 6.912 (5), b = 6.993 (5), c = 9.656 (5) Å, α = 1…
The effect of electron irradiation with energy of 30 keV and fluence up to 7 × 1016 cm−2 on diffuse reflection spectra in situ of coatings based on ZnO powders unmodified and modified with zirconium dioxide and aluminum oxide nanopowders was investigated. The higher radiation stability of coatings based on modified pi…
We have already reported Fe-Ni firms with good soft magnetic properties prepared by using an electroplating method. In our previous studies, we prepared the Fe-Ni films from citric-acid-based baths (CA-baths) and ammonium-chloride-based ones (AC-baths), and confirmed that the coercivity for the AC-baths was lower than…
We propose a method that allows for a fast and accurate reconstruction of the refractive index profile of radially symmetric gradient index lenses fabricated by ion-exchange processes. The presented method enables the reconstruction of the profile up to the 10th polynomial order without direct spatially resolved refra…
Growth of epitaxial III‐nitride (AlGaInN) films has long been confined to single crystal substrates which are crystallographically compatible with the hexagonal GaN (0001) surface. However, for lighting, display, and power electronics applications, growth on amorphous substrates such as fused quartz glass or on polycr…
We have studied carbon-doped magnesium diboride nanoparticles using $^{13}\mathrm{C}$ and $^{11}\mathrm{B}$ NMR in the normal and superconducting states. Measurements of the line shape reveal the role of carbon as a flux-pinning center and, combined with Knight shift measurements, suggest the doping procedure favors t…
We show that an azimuthally polarized beam (APB) excitation of a plasmonic Fano structure made by coupling a split-ring resonator (SRR) to a nanoarc can enhance second harmonic generation (SHG). Strikingly, an almost 30 times enhancement in SHG peak intensity can be achieved when the excitation is switched from a line…
Line start permanent magnet synchronous motors experience different types of failures, including static eccentricity. The first step in detecting such failures is the mathematical modeling of the motor under healthy and failed conditions. In this paper, an attempt to develop an accurate mathematical model for this mot…
Abstract Two cobalt(II) oxaporphyrins (OTPPCoCl and OTPPCoSbF6) are synthesized in this work and are characterized, including by X‐ray crystallography. Both complexes are tested as catalysts in the copolymerization of propylene oxide (PO)/cyclohexene oxide (CHO) and CO2. Polycarbonate is obtained in CHO/CO2 copolymeri…
Classification societies require ship manufacturers to perform nondestructive examination (NDE) of ship weldments to ensure the welding quality of new-building ships. Ships can contain hundreds of kilometers of weld lines and 100% inspection of all welded connections is not feasible. Hence, a limited number of weldmen…
Abstract The spectral analysis of bismuth based halide perovskite materials has been carried out using FTIR, UV‐Vis, photoluminescence and fluorescence time resolved spectroscopy. Methylammonium bismuth iodide (CH 3 NH 3 Bi 2/3 I 3 ) has shown promising results to become a potential candidate for the replacement of le…
Abstract By complexing a bent phosphonate monoester ligand with cobalt(II), coupled with in situ ester hydrolysis, coordination microspheres (CALS=CALgary Sphere) are formed whereas the use of the phosphonic acid directly resulted in a sheet‐like structure. Manipulation of the synthetic conditions gave spheres with di…
Room-temperature ferromagnetism of GaN and doped GaN materials has been reported in nanostructured form. Especially, nanoparticles show ferromagnetic properties at room temperature. In this paper, Ti-doped effects on GaN were deposited on glass and Polyethylene terephthalate (PET) substrates by thermionic vacuum arc a…
Mesoporous C@ZnO hollow spheres were successfully synthesized through a carbon-sphere template combined hydrothermal method. The photocatalytic activities of the samples to rhodamine B (RhB) were investigated, and the sample of 3 wt% carbon has the best photocatalytic activity to RhB. The excellent photocatalytic perf…
Nuclear spin-lattice ($1/{T}_{1}$) and spin-spin ($1/{T}_{2}$) relaxation rates of the cation sites of a candidate quantum spin-liquid ${\ensuremath{\beta}}^{\ensuremath{'}}\ensuremath{-}{\mathrm{EtMe}}_{3}\mathrm{Sb}{[\mathrm{Pd}{(\mathrm{dmit})}_{2}]}_{2}$ and its deuterated sample are presented. The enhanced $1/{T}…
The impacts of emulsions based on commercial oils on the biogenic amine formation and their indices of vacuumed packed sea bass fillets were investigated. The results showed that among biogenic amines, cadaverine, putrescine, spermidine, spermine, serotonin, dopamine, and agmatine were predominant amines in sea bass f…
Abstract A flexible dipyridyl ligand 1,2‐bis(4‐pyridylmethylamino)ethane ( L ) was synthesized and its diverse coordination mode with Zn(II) and Cd(II) in presence of different dicarboxylate renders five novel Metal–Organic Frameworks, namely, {[Zn(L)(BDC)]⋅6.5H 2 O} n ( 1 ), {[Zn(L)(NH 2 ‐BDC)]⋅6.5H 2 O} n ( 2 ), {[C…
The microscopic properties of water confined within different segments of Trpzip4 (TZ4), Trpzip5 (TZ5), and Trzpip6 (TZ6) have been compared for all the states characterized along their folding pathways. In particular, structural ordering, energetics, and dynamics of water have been examined as the peptide unfolds alo…
In order to investigate the mechanism of photo-induced processes of azo molecules doped in polymer, temporal evolution of the absorption spectrum and transmittance for two polarization components were measured under and after optical pumping. A simple model was applied to decompose the contributions from angular hole…
Fe-doped ZnS films of high optical quality were fabricated using vacuum vapor deposition. Preferential crystalline orientation and phase purity of the host ZnS films were increased by the addition of small amounts of Fe, and the spectral shape of the 2–4 μm absorption peak is maintained up to the highest concentration…
