Abstract:

The UV–visible spectra of various thiomolybdates have been studied. Cross-contamination during synthesis and extensive overlap in the spectra have hindered the UV–vis characterization to date. We report the use of multivariate curve fitting for the accurate quantification of the composition of thiomolybdate mixtures as well as the molar absorptivities at key wavelengths of the spectrum of each pure thiomolybdate. The synthesis and isolation of all four thiomolybdates by a common synthetic route using (NH4)2S is also reported. This is the first time that monothiomolybdate has been isolated from

Abstract:

A UV-visible spectral library has been generated after the spectra have been preprocessed with a Fourier analysis. Both the library and unknown spectra are Fourier transformed and are represented by a window of coefficients from the transforms. In order that the optimum window for the coefficients could be determined, synthetic spectra were generated and used to test the effects of band shifts, high-frequency noise, and background fluctuations. Spectra of 24 compounds, many of which were very similar, were measured and processed from 200 to 712 nm. Eight of the samples were treated as unknowns

A library mixture search method originally developed for infrared spectra has been successfully applied to UV-visible spectra. This novel approach for searching a spectral library performs a principal component analysis (PCA) on the entire library of spectra for pure compounds. The library spectra are represented by their PCA scores, and the concentrations (assumed to be unity) are regressed onto these scores. The scores for an unknown spectrum projected onto the PCA basis set are multiplied by the regression matrix to predict pseudo-concentrations or composition indices. After the first pass

Abstract:

In this report, ZnO nanoparticles (NPs) was synthesized by chemical method using Zinc Acetate dehydrate [Zn(CH3COO)2.2H2O)] as precursors and Ethanol and distilled water as solvent. Sodium hydroxide (NaOH) was used to maintain the pH and helps to establish the NPs. The NPs are characterized by XRD, UV-visible spectroscopy and SEM image analysis. The XRD characterization gives the polycrystalline nature of ZnO NPs with the size ~23 nm and ~27 nm calculated by Scherrer’s method and Williamson–Hall method respectively. The crystalline size of these NPs calculated using XRD pattern is validated by

Aim: This study aimed to develop and validate a simple, precise, and cost-effective UV- visible spectrophotometric method for the estimation of jatamansone in Nardostachys jatamansi extract. The analysis parameters were selected following the ICH Q2 (R1) guideline. Methods: Jatamansone solution was scanned across the UV-visible range to identify its wavelength of maximum absorbance. Calibration standards of jatamansone were prepared, and a concentration vs. absorbance calibration curve was plotted. The developed UV-visible spectrophotometric method was utilized to estimate jatamansone in stand

Abstract In this study, MgAl2O4/gC3N4 composite material was successfully synthesized by the impregnation method and characterized by XRD, SEM, EDAX, and UV-visible analysis. The structural properties of the material are obtained from XRD analysis, and the optical properties are investigated by a UV-visible study. The morphological characteristics and compositional analysis of the nanomaterial are studied by SEM with EDAX spectra. The antioxidant activity of the material was examined through a FRAP assay, and the results show it has 90% activity.

Abstract:

This study explores poly(methyl methacrylate) (PMMA)-based composites as potential alternatives to conventional TiO2-based photocatalysts. Specifically, it examines PMMA composites enriched with oxo–titanium(IV) complexes, [Ti8O2(OiPr)20(man)4] (1), [Ti4O(OiPr)10(O3C14H8)2] (2), and [Ti6O4(OiPr)2(O3C14H8)4(O2CEt)6] (3), alongside ruthenium(III) complexes, K[Ru(Hedta)Cl]∙2H2O (4) and [Ru(pic)3]·H2O (5). We assessed the physicochemical, adsorption, and photocatalytic properties of these composites with structural analyses (Raman spectroscopy, X-ray absorption (XAS), and SEM-EDX), confirming the

Abstract:

The TiO2/Ti electrode was successfully synthesized by combining element N and metal Ni on the TiO2 matrix to degrade the organic compound Congo Red under UV-visible radiation. The aim of this study is to obtain Ni@N-TiO2/Ti electrodes and test their performance in degrading Congo Red dye under UV-visible light radiation. The Ni@N-TiO2/Ti electrode was prepared using the Sol-Gel and electrodeposition methods. The presence of nitrogen in N-TiO2 is determined by FTIR and detected at a wavelength of 1.064 cm1. The analysis of UV-Vis DRS indicates an energy gap of 3.06 eV for N-TiO. XRD analysis re
