Abstract:

Spectroscopy of UV-VIS-NIR combined with chemometric analyses was used as a non-destructive technique to build models for the quantitative characterisation of the main compounds of wine. The work in mixtures can give insight into how interferences affect the performance of calibrations in wines. Ethanol, glycerol, glucose, tartaric acid, malic acid, lactic acid, and acetic acid were evaluated as pure compounds and in mixtures. Different pre-treatments for the spectra and modelling strategies such as partial least squares (PLS) regression or Principal Component Regression (PCR) were evaluated.

Abstract:

Ultraviolet-visible (UV-vis) spectroscopy is a spectral measurement technique that relies on Lambert-Beer's law. Due to its user-friendly nature, rapid analytical capabilities, broad applicability, and non-destructive properties, it has gained significant prominence across various scientific disciplines. In the realm of environmental science, UV-vis spectroscopy can be employed for effectively detecting water quality by determining the concentration of heavy metals and related chemicals in water sources.

Abstract:

Zinc sulfide nanoparticles (NPs) were produced through a straightforward and cost-efficient chemical co-precipitation technique, intended for use in the photocatalytic decomposition of methylene blue (MB) dye, both under ultraviolet and visible light exposure. To evaluate the synthesized nanoparticles, various analytical tools including ultraviolet-visible (UV-Vis) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffractometry (XRD) were employed. The XRD analysis confirmed the cubic symmetry of the synthesized NPs. SEM analysis revealed that

The compact integration of semiconductor TiO2 nanoparticles (NPs) into the 3D crossed region of stacked plasmonic Ag nanowires (NWs) enhanced the photocatalytic activities through synergistic effects between the strong localized surface plasmon resonance (LSPR) excitation at the 3D cross-points of the Ag NWs and the efficient hot electron transfer at the interface between the Ag NWs and the TiO2 NPs. This paper explored new hybrid nanostructures based on the selective assembly of TiO2 NPs onto 3D cross-points of vertically stacked Ag NWs. The assembled TiO2 NPs directly contacted the 3D Ag NWs
