This study shows Coffee Silver Skin removes Norfloxacin via adsorption. Regeneration with UV/TiO₂ achieves full degradation in 6 h. Reuse up to 3 cycles is possible, offering sustainable wastewater treatment.

This study introduces microwave-assisted digestion and dispersive magnetic SPE with ICP-OES to measure major and trace elements in lignocellulosic biomass with high accuracy and sensitivity.

This study identifies novel 3-oxazolines in cocoa and chocolate as potential aroma precursors, providing new insights into chocolate flavor formation and enhancement.

Soybean flour–CMC biopolymer coating enhanced paper strength by 61.8% and showed up to 89% antibacterial reduction against E. coli, offering promise for sustainable packaging.

A new spectroelectrochemical approach integrates UV/vis absorption, photoluminescence, and Raman spectroscopy to provide simultaneous signals for richer chemical analysis in one experiment.

Gold–silver nanoclusters with fixed Au:Ag ratio were matured under different conditions. Fluorescence and synergism varied, with optimum at 37 °C, 2.5 h, and quenching by Cu(II)/Fe(III) was evaluated.

Brazilian stingless bee honey was analyzed via FT-MIR, NMR, and GC–MS. Chemometrics revealed species differences and correlations between phenolics and antioxidant capacity.

ATR-FTIR microspectroscopy with multivariate analysis differentiates Saccharomyces strains by autolytic behavior, detecting mannans and glucan changes relevant for wine fermentation.

Fourier-transform NIR and volatilome-based HS-GC–IMS/MS methods fingerprint peach ripening stages, allowing PCA and PLS-DA models to differentiate ripeness and variety for optimal harvest.

A rapid FTIR method was developed to measure hydrogen isotope ratios in water. Using molecular bending vibrations, it achieved ~0.5% sensitivity and ~1% deviation, proving reliable for H2O/D2O mixtures.
