Chemical and organoleptic changes of curd cheese stored in new and reused active packaging systems made of Ag-graphene-TiO-PLA.

The study reports obtaining, characterization and evaluation of the preservation efficacy of nano-Ag-graphene-TiO-polylactic acid (PLA) film during the storage of the curd cheese. The reusability of the active package was also evaluated. The mechanical resistance of the film was improved by 30% following the composite addition.

Modifying the Silver-Titania Nanocomposites with Carbonaceous Materials to Remove the Pollutants from Domestic Waste Water.

The aim of this study was to prepare and characterize nanostructured composites based of TiO₂, carbonaceus materials (GN or GO) and Ag and the test their capacity to remove the pollutants from domestic wastewater. The composites were characterized by IR and UV-Vis spectroscopy, X-ray diffraction, electron microscopy and nitrogen adsorption-desorption measurements. The photocatalytic activity was measured from the experiment of salicylic acid (SA) degradation.
