Mesoporous silica matrices derived from sol-gel process assisted by low power ultrasonic activation [PDF]

, 2009
The present work contributes to elucidating the differences between silica gels obtained by low doses ultrason- ic activation, and those obtained by the conventional method, termed as classical sol gel.

Beyond Sol-Gel: Molecular Gels with Different Transitions

Gels, 2023
The existence of sol–gel transitions is one of the most manifest properties of molecular gels. These transitions reflect their nature since they correspond to the association or dissociation of low weight molecules through non-covalent interactions to ...

Selective Binding and Elution of Aptamers for Pesticides Based on Sol-Gel-Coated Nanoporous Anodized Aluminum Oxide Membrane

Nanomaterials, 2020
Sol-gel-based mesopores allow the entry of target small molecules retained in their cavity and aptamers to bind to target molecules. Herein, sol-gel-based materials are applied to screen-selective aptamers for small molecules, such as pesticides.

Evaluation of self-healing properties of inhibitor loaded nanoclay-based anticorrosive coatings on magnesium alloy AZ91D

Journal of Magnesium and Alloys, 2018
This study emphasizes on the evaluation and comparison of the anticorrosive properties of sol–gel coatings with and without inhibitor loaded nanocontainers. In this case, naturally available clay nanotubes (halloysite) were loaded with cationic corrosion
