To reduce the emissions of internal combustion engines, ceria-based catalysts have been widely investigated as possible alternatives to more expensive noble metals. In present work, a set four different materials was prepared via hydrothermal synthesis, studying effect Cu and Mn dopants both in binary ternary oxides. situ Raman analyses were carried out monitor behaviour defect sites throughout thermal cycles during soot oxidation reaction. Despite ceria doped with 5% featured highest...
Surface-enhanced Raman scattering (SERS) is a powerful and sensitive technique for the detection of fingerprint signals molecules investigation series surface chemical reactions. Many studies introduced quantitative applications SERS in various fields, several methods have been implemented each specific application, ranging performance characteristics, analytes used, instruments, analytical matrices. In general, very few validated according to international guidelines. As consequence,...
In recent decades, climate change has become a major issue that needs to be addressed. Many efforts have been made on the reduction of CO2 emissions and its conversion in energy carriers high value-added products such as methane, methanol, dimethyl-ether, hydrocarbons. The present study focuses development catalysts for hydrogenating which is useful chemical an alternative liquid fuel. According literature, In2O3-based are particularly selective hydrogenation reducing production CO even at...
Silver-coated porous silicon and polydimethylsiloxane (PDMS) are systematically analyzed as substrates for surface-enhanced Raman scattering (SERS). They were selected representative metal–dielectric nanostructures characterized by different morphology substrate dielectric constant which is reflected in the electromagnetic near-field intensity spectra. The study conducted using 4-mercaptobenzoic acid probe molecule with aim to compare efficiency homogeneity of signal on substrates. A larger...
Copper-ceria mixed oxides are widely considered promising catalysts for oxidation reactions, especially when the participation of lattice oxygen is required. However, mechanistic understanding these catalytic systems still incomplete, due to their considerable complexity. In fact, copper doping ceria results in formation a significant number different interacting sites continuous evolution during processes. present study, pure and Cu-doped samples were deeply investigated through combined...

Abstract Variations occurring in coffee beans during roasting are ascribable to several chemical-physical phenomena: quickly track the whole process and ensure its reproducibility, a analytical technology (PAT) approach is needed. In this study, method combining in-line Fourier transform near-infrared (FT-NIR) spectroscopy chemometric modelling was investigated get real-time practical knowledge about effects on coffee’s composition. In-line spectra were acquired by inserting NIR probe into...

Neonatal diabetes (NDM) is a rare genetic disorder diagnosed in infants under six months of age, characterized by persistent hyperglycemia resulting from insufficient or absent insulin production. Unlike the more common forms diabetes, such as type 1 (T1D) and 2 (T2D), NDM predominantly caused monogenic mutations affecting ATP-sensitive potassium (K-ATP) channels pancreatic beta cells. The most involved are found KCNJ11 ABCC8 genes, which encode Kir6.2 SUR1 subunits K-ATP channel,...
