This study presents the spectral characterization of TiO2 nanoparticles (NPs) functionalized with three porphyrin derivatives: 5,10,15,20-(Tetra-4-aminophenyl) porphyrin (TAPP), 5,10,15,20-(Tetra-4-methoxyphenyl) porphyrin (TMPP), and 5,10,15,20-(Tetra-4-carboxyphenyl) porphyrin (TCPP). UV-Vis absorption and Fourier transform infrared spectroscopy–attenuated total reflection (FTIR-ATR) spectroscopic studies of these porphyrins and their complexes with TiO2 NPs were performed.

The depth-profiles of accelerated aged triterpenoid dammar and mastic varnishes, which had been uncovered by optimized KrF excimer laser ablation (248 nm, 25 ns), were examined by ultraviolet–visible (UV/VIS) spectrophotometry and attenuated total reflection (ATR) Fourier transform infrared (FT-IR) spectroscopy. The results reflect both the optical properties at the bulk (UV/VIS) and the surface (ATR/FT-IR) and establish the presence of degradation gradients across the depth of the degraded natural resin films.

AbstractIn the current study, we report the antifungal, antioxidant, and computational study of (E)‐7‐(4‐(trifluoromethyl)benzylidene)‐1,2,6,7‐tetrahydro‐8H‐indeno[5,4‐b]furan‐8‐one (FMBIF). The structure of the FMBIF was confirmed using spectroscopic techniques such as UV‐Vis, FT‐IR, 1H NMR, 13C NMR, and HRMS. Antifungal activity of the FMBIF was evaluated against four fungal strains namely Rhizopus oryzae, Mucor mucido, Aspergillus niger, and Candida albicans. The FMBIF was found to exhibit a good spectrum of antifungal activity against all the tested fungal strains. Additionally, it was als

Abstract:

Transferrin belongs to a class of monomeric glycoproteins, which sequestrate and transport iron inside the body. Apart from iron, transferrin binds with various other metal ions and is assumed to deliver medicinally important metal ions to cells. Hence, the investigation of binding characteristics may provide crucial information for new drug developments. To study the biological impacts of medicinally important metal ions, in this work, we explored the binding behavior of Rh(III) ion with serum apo-transferrin (ApoHST) using FT-IR and UV-Vis spectroscopy. In FT-IR, interaction of Rh(III) with

ABSTRACT. In this research, theoretical and experimental investigation was performed on the structural and spectral data of aminothiophenol isomers. The theoretical electronic structure analyses were performed by density functional theory at the B3LYP level with the LanL2DZ basis set in the gas phase of the isolated compounds at the ground state. Potential energy distribution analysis was performed to determine the assignments of the vibration bands. Experimental and theoretical spectroscopic data were compared.

Abstract:

Spectro-electrochemistry combines spectroscopic and electrochemical techniques, enabling time-resolved and in-situ measurements of phenomena occurring at charged electrode surfaces. Surface-enhanced Raman spectroscopy (SERS) yields highly specific information about the structure and composition of molecules. Coupling SERS with electrochemical experiments gives insight into changes near the electrode surface under polarization. In-situ SERS and electrochemical measurements are demonstrated to provide information on the electrolyte-electrode interface in three different applications: (1) specifi

Abstract:

In continuing studies of the aggregation behaviour of squaraine dyes in DMSO-water mixtures, we have examined a series of symmetrical anilino-based squaraines with increasing N-alkyl chain length (n-butyl, n-octyl, and n-dodecyl). The aggregation behaviour was assessed through UV/vis spectroscopic and Dynamic Light Scattering (DLS) studies with quantitative interpretation based on exciton theory. This class of N-alkyl squaraines forms two distinct solution aggregates, Type J and Type H, depending on the composition of the DMSO-water medium. DLS measurement of the aggregates in the Type J and T

We report on the deposition and characterization of hafnium silicate and aluminium silicate thin films for different applications in optics and electronics. Pulsed laser deposition in a controllable oxygen atmosphere was used as a processing technique, with optimized parameters in terms of laser wavelength, laser fluence and oxygen pressure. The thin films were investigated using atomic force microscopy, spectroscopic ellipsometry, UV–VIS spectroscopy and X-ray photoelectron spectroscopy. The morphological investigations evidenced uniform layers with low roughness (in the order of nanometres).

High-index contrast lithium niobate waveguides, fabricated by the High Vacuum Vapor-phase Proton Exchange (HiVac-VPE) technique, are very promising for increasing both the optical nonlinear and electro-optical efficiencies of photonic integrated devices. So as to play this role effectively, it is mandatory to know the crystallographic phase composition of waveguides and the position of protonated layers for appropriate tailoring and optimization based on the intended applications. In addition, the estimation of structural disorder and electro-optical properties of the waveguides are also of hi

This study was undertaken to investigate the interaction between the sodium channel blocker amiloride (AML) and human serum albumin (HSA).

Our findings revealed that AML specifically binds to Sudlow’s site II, located in subdomain IIIA of HSA, and that the complex formed is stabilized using van der Waals hydrogen-bonding and hydrophobic interactions.
