Alkaline-earth doped LaCoO3 has been found to be promising as conductive oxides instead of standard metals for use as electrodes. Electrical conductivity has a maximum, σ = 4.4 × 103 S cm−1, in La0.6Sr0.4CoO3. We believe that the increase in mobility was caused by the decrease in the Co–O bond length.
Fatigue crack growth tests were carried out in high-pressure gaseous hydrogen at 90 MPa at room temperature for SUS316-based stainless steels containing different amounts of Ni and Cr, and the effects of these alloying elements on fatigue crack propagation were investigated. The fatigue crack growth rate of the SUS316…
The graft copolymerization of 2-hydroxyethylmethacrylate (HEMA) and methacrylic acid (MAA) onto a biodegradable and biocompatible polymer, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV), has been investigated. The one-step process was conducted in aqueous media using for the first time a cationic photoinitiator,…
The present study was aimed to investigate the antibacterial activity of 5 different nanoparticles against fish bacterial pathogens viz., Aeromonas hydrophila, Bacillus subtilis, Vibrio harveyi, Vibrio parahaemolyticus and serratia sp. The antibacterial activity of the chosen nanoparticles was assessed by well diffusi…
The potentiostatic anodization of metallic tungsten has been investigated in different solvent/electrolyte compositions with the aim of improving the photoelectrochemical performances of the tungsten oxide layer. Among the explored electrolytes, the anodization in the NMF/H2O/NH4F solvent mixture was found to produce…
Abstract— Multi‐primary‐color (MPC) display technology is one of the fastest emerging research areas in recent years. Wide‐color‐gamut display devices have been required for visually sufficient and/or accurate color reproduction. It is well known that MPC displays can reproduce accurate colors with high efficiency. In…
The objective of this study is to utilize the pH sensitivity of modified silica nanoparticles (SNIL) by imidazole-based ionic liquid for oral delivery of insulin. In the first time, the imidazole was covalently attached to the 3-trimethoxysily-lpropyl chloride with replacement of all the chlorine atoms. Then, a silica…
Vibrational circular dichroism (VCD) spectra were recorded on benzene-d(6) gels formed by chiral low molecular mass gelators (LMGs), trans(RR)- or trans(SS)-N,N'-alkanoyl-1,2-diaminocyclohexane (denoted by RR-C(n) or SS-C(n), respectively; n = the number of carbon atoms in an introduced alkanoyl group). Attention was…
As the level of complexity of nanoscale materials increases, new methods for quantifying accurate structure–property relationships must be found. The addition of more structural degrees of freedom can represent significant challenges to conventional experiments, but serves only to increase the total number of calculat…

A general approach was developed to synthesize a series of cobalt, manganese, and iron phosphate frameworks in deep-eutectic solvents through tuning important reaction parameters including temperature, time, and addition of water.
In this communication we report a p-sulfonatocalix[4]arene coated ZnS quantum dots "cup type" highly stable optical probe for the detection and determination of menadione (VK(3)) with high sensitivity and selectivity. The detection of VK(3) depends on supramolecular host-guest chemistry.
With the aim that to confirm the need for humidity control in the environment in which textile sample are visually and instrumentally analyzed, three different pre-conditioned fabrics sample of cotton, polyester and silk were treated at a fix temperature of 21?C. The relative humidity adjusted to four levels: 55%, 65%…
Crystallization kinetics and stability are very important and essential parameters for glasses and glass ceramics. These parameters are highly dependent on initial composition as well as processing conditions. Thus, the role of modifier cation on thermal parameters have been studied for AO-SiO 2 -B 2 O 3 -Y 2 O 3 (A =…
Different derivatives of the Schiff base (SB) N,N′-bis(2-hydroxybenzylidene)-2,2,-dimethylpropane-1,3,-diamine, LH2, have been used to obtain a series of compounds of which we here report the synthesis, structural determination and magnetic study. [Mn(SB)(H2O)]ClO4 and [NEt4]3[Fe(CN)6] react in methanol to give the ci…
The name of Vertisol is derived from Latin “vertere” meaning to invert. This case restricts development of soil horizons in profile. These soils have the capacity to swell and shrink, inducing cracks in the upper parts of the soil and distinctive soil structure throughout the soil. The formation of these specific feat…
We report a stainless steel/multi walled carbon nanotubes/polyaniline (SLS/MWCNTs/PANI) capacitor electrode capable of operating in a physiological electrolyte and in serum. The specific capacitance of SLS/MWCNTs/PANI reaches 401 F g(-1) in the physiological electrolyte and 326 F g(-1) in serum. The capacity loss at 6…
The main goal of this work was to use rice straw (RS) in the production of environmentally sound composites using corn based adhesives (CA). Treatments of RS with NaOH and hot-water were undertaken to evaluate the effect of such treatments on the performance of produced composites. The influence of composite density,…
Finite element modeling based on solving the Nernst-Planck equation was used to describe the evolution of current densities and pH distribution at the surface of a bimetallic system. This system consisted of five single copper particles fabricated on isolated, thin-film aluminum electrodes exposed to dilute aqueous ch…
The aggregates of a cationic polythiophene (PT1) formed in poor solvent in the presence of sugars showed the distinct circular dichroism activity, the intensity being well correlated with the specific optical rotation [α] of sugars: therefore, the present system is useful as a novel sugar structure reading-out method.
