Structural, conformational, and spectroscopic investigations of methyl-eugenol were made theoretically at the IR, Raman, and UV-vis spectra were investigated and analyzed in light of the computed quantities. Conformational analysis was carried out with the help of total energy vs. dihedral angle curves for different tops, yielding 21 stable conformers, out of which only two have energies below the room temperature relative to the lowest energy conformer. The effect of the solvent on different molecular characteristics was investigated theoretically. MEP and HOMO-LUMO analysis were carried out and barrier heights and bioactivity scores were determined. The present investigation suggests that the molecule has three active sites with moderate bioactivity. The solvent-solute interaction is found to be dominant in the vicinity of the methoxy moieties.

Thin films of CuSn Gd S were prepared on soda-lime glass substrates using spin coating in a sulfur-rich environment. We investigated how doping CuSnS with gadolinium (Gd) affected its structural, morphological, and optical properties using X-ray diffraction (XRD), Raman spectroscopy, field emission scanning electron microscopy (FE-SEM), and UV-Vis spectroscopy. XRD showed that all samples had a polycrystalline monoclinic structure, while FE-SEM revealed a mix of spherical and polygon-shaped grains.

This study reports the enhanced photoelectrochemical (PEC) performance of TiO/α-FeO heterostructure films fabricated a sequential aerosol-assisted chemical vapour deposition (AACVD) of hematite at 450 °C, followed by atmospheric pressure CVD (APCVD) of anatase TiO with controlled thickness. Structural analyses (XRD, Raman, XPS) confirmed phase purity and oxidation states, while UV-vis spectroscopy revealed a narrowed bandgap and extended visible light absorption for the heterostructures compared to pristine films. The optimized TiO/α-FeO (8 min) photoanode achieved a photocurrent density of 1.

The green synthesis method is a significant approach that offers several advantages, including simplicity, rapidity, and cost-effectiveness in the synthesis of nanoparticles. Iron nanoparticles were synthesized in this work using waste banana peel extract as a capping and reducing agent. The produced nanoparticles were then subjected to a number of characterization procedures, such as Raman spectroscopy, X-ray diffractometry (XRD), zeta potential analysis, Fourier transform infrared (FT-IR) spectroscopy, ultraviolet-visible (UV-VIS) absorption spectroscopy, field scanning electron microscopy (FE-SEM), energy dispersive X-ray analysis (EDX), and thermogravimetric analysis (TGA).

Background: Thermoelectric (TE) materials can directly convert heat into electricity, which is beneficial for energy sustainability. Organic conducting polymers are TE materials that have drawn significant attention owing to different favorable properties, such as good processability, availability, flexibility, and intrinsically low thermal conductivity. Among the organic TEs, poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) is the most extensively investigated material because of its stability and high electrical conductivity.
