Abstract This study demonstrates direct fabrication of a visible-light-responsive LaTiO2N film via nitridation of the La2Ti2O7 film hydrothermally prepared on a titanium substrate as an oxide precursor. The thickness and surface morphology of the film were not significantly affected by nitridation. An anodic photocurr…
Electrospun poly(vinyl chloride) (PVC) nanofibrous were prepared by electrospinning. Various concentration of polyurethane (PU) were added to PVC solution for plasticization of the electrospun nanofibrous. The pristine and plasticized nanofibrous were characterized by field emission scanning electron microscopy (FE-SE…
We have tried suppressing variation of switching voltages which hinder the practical application of resistive switching random access memory. On the basis of a filament model, fabrication of the top electrode with small enough size against the filament size and confining the filament are thought to be the solutions. I…
The present work is devoted to the study of the thermo-optical properties of liquid crystals doped with traces of fullerene C(60) at the vicinity of the nematic-smectic-A phase transition. By using the time-resolved Z-scan technique, we measure the temperature dependence of the thermo-optical coefficient and the therm…
Sucrose, the main component of table sugar, present in nearly every household and quite radiation sensitive, is considered as an interesting emergency dosemeter. Another application of radiation-induced radicals in sugars is the detection of irradiation in sugar-containing foodstuffs. The complexity of electron parama…
To investigate the electronic structure of the intermetallic compound CeCoGe2, we performed electrical resistivity (ρ), Seebeck coefficient (S), and thermal conductivity (κ) measurements in a temperature range of 10-300 K. For comparison, the non-magnetic counterpart LaCoGe2 is also studied. It is found that CeCoGe2 e…
Quantum Hall effects on the complex Grassmann manifolds ${\mathbf{Gr}}_{2}({\mathbb{C}}^{N})$ are formulated. We set up the Landau problem in ${\mathbf{Gr}}_{2}({\mathbb{C}}^{N})$ and solve it using group theoretical techniques and provide the energy spectrum and the eigenstates in terms of the $SU(N)$ Wigner $\mathca…
Poly(vinyl chloride‐ co ‐vinyl acetate) (PVVA)/nano‐SiO 2 composite resin was prepared by radical suspension polymerization of the monomers in the presence of fumed nano‐SiO 2 particles premodified with γ‐methylacryloxypropyl trimethoxysilane. The cool dioctyl phthalate absorption percentage, granule porosity, and spe…
We analytically propose radially oscillating and quasi-guided surface plasmon polaritons (SPPs) by designing the outer and core dielectric permittivities ε(a) and ε(c) of a cylindrical metallic nanotube. When the propagation constant satisfies √ε(a)<Re(k(z)/k(0))<√ε(c), the electromagnetic field propagates along the r…

Space is characterized by risk and uncertainty. As humans play an important role in long-duration space missions, the ability to make risky decisions effectively is important for astronauts who spend extended time periods in space. The present study used the Balloon Analog Risk Task to conduct both behavioral and fMRI…
Purpose – To study the inhibition effect and mechanism of the Momordica charantia extract (BM) to 20 A carbon steel in 5 per cent HCl. Design/methodology/approach – The weight loss, polarization curve, infrared spectrum (IR) analysis and X-ray photoelectron spectrum (XPS) analysis were carefully investigated to indica…
Thin films of CuInSe2 were grown on fluorine doped tin oxide (<10 Ω/) coated glass using the electrodeposition technique. The electrodeposition was carried out potentiostatically using an aqueous bath consisting of solutions of CuCl2, InCl3 and SeO2 with ethylenediamine-dihydrochloride (EDC) added for complexation. Cu…
A convenient method for the synthesis of β-unsubstituted meso-aryl substituted tripyrranes was developed. Pyrrole condensed with aldehyde in acidic aqueous to produce tripyrranes selectively in moderate yield. The selectivity for tripyrranes depended on the electronic and steric properties of aldehyde, the stoichiomet…
ABSTRACT In order to evaluate the relationship between dispersion and ultrasonic time, dynamic light scattering experiment was carried out on both 0.20 g/L xyloglucan solution and 0.20 g/L β‐galactosidase‐degraded xyloglucan solution with different time intervals. Data showed that the variation trends of particle size…
The atomic structures of non-polar GaN(101¯0), (112¯0) and semipolar GaN(202¯1), (202¯1¯) surfaces were studied using ab initio calculations within density functional theory. The bulk-like truncated (1 × 1) structure with buckled Ga-N or Ga-Ga dimers was found stable on the non-polar GaN(101¯0) surface in agreement wi…
Abstract Treatment of bis(trimethylsilylethynyl)porphyrin with strong acids afforded doubly oxoethano-fused porphyrin with perfect regioselectivity. The oxoethano-fused porphyrin was more electron deficient than meso-acetylporphyrin because of the coplanar orientation of the carbonyl groups to the porphyrin π system.
The influence of electrochemistry on the coagulation of blood on metal surfaces was demonstrated several decades ago. In particular, the application of cathodic currents resulted in reduced surface thrombogenicity, but no molecular mechanism has been so far proposed to explain this observation. In this article we used…
One can achieve a more uniform native-state structure and remove scattering concerns by using solution phase samples. To avoid strong background from bulk solvent, one can form thin (~100 μm) lms of solution and dry these in a controlled way, using, for example, a closed cell with humidity control. e hydration can be…
We developed a new crystallization technique combining the solution stirring technique and crystallization at the interface between high-concentrated hydrogel and solution (the on-gel stirring technique). The solution stirring effect on the crystal quality of insulin was evaluated by an average difference between temp…
