Carboxylic acids and esters as scaffold for cavities in porous single layer anti-reflective coatings of silica-titania with excellent optical and mechanical properties
Anti-reflective (AR) single layer of silica-titania (SiO2-TiO2) coatings were obtained from sols containing pyromellitic dianhydride (PMDA) derivatives and Ti and Si precursors on glass substrate by dip-coating method. The coatings showed very high optical quality and the transmission was improved to up to 98.5%. Furthermore, the coatings also presented good mechanical stability.
Gradients of Al/Al2O3 nanostructures for screening mesenchymal stem cell proliferation and differentiation
By decomposing a molecular precursor we fabricated a novel surface based on an aluminium/aluminiumoxide composite incorporating nanotopography gradient to address high-throughput and fast analysis method for studying stem cell differentiation by nanostructures. Depending on the topography of the nanostructures, mesenchymal stem cells exhibit a diverse proliferation and differentiation behavior.
