Zinc oxide (ZnO) nanoparticles have been prepared by a wet chemical method, from zinc acetate and LiOH ethanol-based solutions. The resulted nanoparticles were dispersed in a solvent. The effect of solvent (ethanol or butanol) and surfactant (polyeth

Hybrid organic–inorganic materials can organize into layered crystalline structures through self-organization when bridged silsesquioxanes are used in the sol–gel synthesis. Crystallization is, however, also observed in hybrid materials when 3-gl

Mesoporous and dense sol−gel titania films have been synthesized and processed in similar conditions to make a comparative study of crystallization to anatase in porous and dense samples. We have performed a correlative analysis combining THz spect

Processing of mesoporous films is a critical step that needs a careful control and comprehension of the chemical−physical phenomena that governs evaporation induced self-assembly. We have used time-resolved infrared spectroscopy to study two of the

A new sol–gel synthesis based on chloride compounds as precursors has been used to prepare bismuth titanate (BT) films. The films have been deposited by dip-coating and fired at different temperatures in air; they remain amorphous up to 500°C, and

Thin films of titania–ceria have been prepared via sol–gel processing by employing titanium and cerium chloride compounds in highly acidic conditions for the precursor sol. This sol–gel route allows obtaining titania–ceria and cerium titanate

Organization of nanomaterials through self-assembly is an important example of disorder to order evolution of nanoscaled systems. Mesoporous materials show an ordered porous structure at the mesoscale (2−50 nm) whose formation is driven by the fast

Fabrication of hierarchical porous thin films with controlled pore dimension and shape is a current challenge in materials science. In this work, bimodal hierarchical hybrid organic−inorganic thin films with pores in the meso and macro range have b
