Iron oxide ornamented carbon nanotube nanocomposites (Fe3O4.CNT NCs) were prepared by a wet-chemical process in basic means. The optical, morphological, and structural characterizations of Fe3O4.CNT NCs were performed using FTIR, UV/Vis., FESEM, TEM; XEDS, XPS, and XRD respectively. Flat GCE had been fabricated with a thin-layer of NCs using a coating binding agent. It was performed for the chemical sensor development by a dependable I-V technique. Among all interfering analytes, 3-methoxyphenol (3-MP) was selective towards the fabricated sensor. Increased electrochemical performances for example elevated sensitivity, linear dynamic range (LDR) and continuing steadiness towards selective 3-MP had been observed with chemical sensor. The calibration graph found linear (R2 = 0.9340) in a wide range of 3-MP concentration (90.0 pM ~ 90.0 mM). The limit of detection and sensitivity were considered as 1.0 pM and 9×10-4 μAμM-1cm-2 respectively. The prepared of Fe3O4.CNT NCs by a wet-chemical progression is an interesting route for the development of hazardous phenolic sensor based on nanocomposite materials. It is also recommended that 3-MP sensor is exhibited a promising performances based on Fe3O4.CNT NCs by a facile I-V method for the significant applications of toxic chemicals for the safety of environmental and health-care fields.
The facile hydrothermally synthesized (at low temperature, in alkaline medium of pH 10.5) nanosheets (NSs) of MnO<sub>2</sub>/Gd<sub>2</sub>O<sub>3</sub>/SnO<sub>2</sub> are well crystalline-doped ternary metal oxides.
Nanocrystalline Tb4O7 was fabricated by the calcination of its precursor, which was prepared by the precipitation method using NaOH as a precipitant. The phase changes accompanying the thermal treatment of the terbium parent were monitored using X-ray diffractometry (XRD) and thermogravimetry (TGA). The Calcination was performed over the temperature range of 300-700 degrees C. The texture of the produced nanocrystalline Tb4O7 samples was investigated using field-emission scanning electron microscopy (FE-SEM) and nitrogen adsorption measurements at -196 degrees C. Transmission electron microscopy (TEM) was used to determine the crystallite size of the obtained Tb4O7. The obtained results reveal that Tb4O7 with crystallites that measured 6-12 nm was formed at 400 degrees C. The crystallite size increased to 15-29 nm for the sample calcined at 700 degrees C. The electrical conductance properties of the different calcined samples were investigated over the temperature range of 150-500 degrees C. The electrical conductivity was observed to increase with the calcination temperature.
In the present study, a polyvinyl chloride-based barium tungstate ion-exchange membrane was synthesized by sol–gel method. The structure of membrane was studied in terms of Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy. X-ray diffraction analysis confirms crystalline form of the composite membrane without any other impurity. Scanning electron microscopy and Fourier transform infrared spectroscopy analysis show the uniform arrangement of particles in the membrane with crack-free surface structure and presence of different functional groups of the organic-inorganic materials. The electrochemical properties like surface charge density ( D), transport number and mobility ratio of the ion-exchange composite membrane were theoretically evaluated and compared with observed values using “Teorell, Meyers and Sievers” method. Transport number follows the order as KCl <NaCl < LiCl < NH 4 Cl, while the surface charge density showed reversed order. The results showed that the low concentration of electrolytes favors the high mobility of univalent cation in the present study. The above result proves the analytical utility of polyvinyl chloride-based barium tungstate ion-exchange membrane in environmental management.
Abstract The sequestrant is a substance used to cure bile salt diarrhea. They bind to bile salts by hydrophobic and electrostatic forces to stop them from contact with colon mucosa. The block copolymer could be used as bile salt binding agents. Herein, the physicochemical parameters between bile salt and block copolymer have been studied for a new potential sequestrant. The mixed micellization behavior of bile salt, sodium deoxycholic acid (NaDC) with pluronic (F‐127) was investigated by the tensiometry method. Various micellar and thermodynamic parameters were computed. The results of the present study have been analyzed by using different theoretical models for mixed binary systems. The obtained data indicate attractive interactions (synergistic interactions) among two components upon mixing. Silver nanoparticles (AgNPs) were synthesized by using a chemical reduction method. We used single and mixed amphiphilic solution in different compositions for stabilizing silver nanoparticles. The resulting silver sol was analyzed using UV‐visible spectroscopy and scanning electron microscope (SEM).
