Background: The volatile composition of Ruché, a red wine produced from a native grape in Piedmont (Italy), was investigated using headspace-solid phase microextraction (SPME) coupled to gas chromatography-mass spectrometry (GC/MS). The main volatile compounds of the wine were identified and quantified. Chemometric techniques were applied to identify features and possible clusters among the different samples.

The monodisperse SiO core was obtained by the classical Stöber method and then coated with a thin layer of TiO, followed by calcination or hydrothermal treatments. The properties of SiO@TiO core-shell NPs resulted from the synergy between the photocatalytic properties of TiO and the adsorptive properties of SiO.
