Publikováno v: Thin Solid Films. 517:5881-5887

In this work innovative antiscratch sol–gel coating films deposited on a soda–lime glass substrate are examined. Sol–gel coatings of different composition (TiO 2 , TiO 2 /B 2 O 3 , ZrO 2 and ZrO 2 /B 2 O 3 ) were prepared starting from Titanium

Reuse of ground waste glass as aggregate for mortars

Autor: Valeria Corinaldesi, G. Gnappi, Giacomo Moriconi, A. Montenero

Publikováno v: Waste Management. 25:197-201

This work was aimed at studying the possibility of reusing waste glass from crushed containers and building demolition as aggregate for preparing mortars and concrete. At present, this kind of reuse is still not common due to the risk of alkali-silic

Biocompatible layers of hydroxyapatite and fluorhydroxyapatite were grown on Ti substrates by means of dip-coating into sol–gel. In order to improve the adhesion of apatite-based coatings, the substrates were a priori covered with calcium titanate.

Publikováno v: Integrated Ferroelectrics. 22:35-43

PZT and PLZT precursor solutions were prepared by a sol-gel route, varying the Zr/Ti ratio and the La doping level. They were characterized by TGA coupled with FT-IR. Reactions taking place during heat treatments are discussed. Composition of PZT and
