In this work a comprehensive study on a new active packaging obtained by a hybrid organic-inorganic coating with antimicrobial properties was carried out. The packaging system based on polylactic acid was realised by sol-gel processing, employing tetraethoxysilane as a precursor of the inorganic phase and polyvinyl alcohol as the organic component, and(More)
PURPOSE The potential application of hybrid systems based on silicon alkoxides and polyethylene glycol 400 as drug delivery systems was studied. METHODS They were synthesized using the sol-gel technique, using ketoprofen as a model drug. The preparation of the materials and their characterization by X-ray diffraction, infrared spectroscopy,(More)
UNLABELLED Self-cleaning photocatalytic coatings for biocalcarenite stones, based on TiO2 nanoparticles obtained by sol-gel processes at different pH values and also adding gold particles, have been investigated. The selected test material is a biocalcarenite named "pietra di Lecce" (Lecce stone), outcropping in Southern Italy. Scanning electron microscopy(More)
Commonly employed in food packaging, paper-based materials require barrier properties to guarantee food safety. If used in direct contact with food, packaging is usually produced with materials and processes that could compromise its recyclability. In order to search for more sustainable solutions, the researchers of CIPACK (Interdepartmental Centre for(More)
