Structural Modifications and Associated Properties of Lanthanum Oxide Doped Sol−Gel Nanosized Titanium Oxide
TL;DR: In this paper, a solution sol−gel method was used to synthesize nanosized titanium oxide with and without addition of lanthanum oxide, which was characterized by thermal analysis and IR spectroscopy.

Effect of aging time and concentration of aging solution on the porosity characteristics of subcritically dried silica aerogels
TL;DR: In this paper, the effect of concentration of aging solution and duration of aging on the development of pore characteristics of silica aerogels was examined and the results presented in this paper provided data for designing the mesoporous silica gels through subcritical drying technique.
