Photoacoustic analysis of the evolution from sols to aged gels: Comparison of different initial titania sols

The use of correlation analysis of photoacoustic signal changes during the sol-gel-aging evolution of titania sols prepared from the hydrolysis of titanium n-butoxide in alcoholic, aqueous, and micellar media which provide different initial conditions and different evolution pathways is proposed. Th...
