Recent sol‐gel techniques enable bioactive composite layers to be prepared by the
embedding of bioactive compounds, biomolecules (BMs) and cellular systems within …

The sensing of a chemical environment is achieved mainly in the surface by interactions of
the sensor material with its chemical surroundings. Therefore, porous structure control is key …

This study focuses on the transition from the paste state to the solid state which occurs
during the hardening of metakaolin‐based Na‐geopolymers. The occurrence of primary …

The oxidation of dibenzothiophene (DBT) to dibenzothiophene-sulfone (DBT-sulfone) has
been a topic of particular interest in the past few years, as a possible technique to remove …

Entrapment of biomolecules in silica-derived sol− gels has grown into a vibrant area of
research since it was originally demonstrated. However, accessing the consequences of …

Abstract Two PDMS-SiO 2-TiO 2-CaO porous hybrid materials were prepared using the
same base composition, precursors, and solvents, but following two different sol-gel …

The UV curing technique in combination with the use of waterborne resins is very attractive
since it gives the opportunity to get solid coatings by means of ecofriendly processes. We …

Lead zirconate titanate (PZT) fibers are prepared by the sol–gel method using acetic acid
and methacrylic acid to control the pH of the PZT precursor sol. The chemical evolution of …

Porous materials occur widely and have many important applications. They can, for
example, offer a convenient method of imposing fine structure on adsorbed materials. They …

Silica–alumina mixed oxide aerogels, with 5, 10, 15, 20, and 25 wt% of alumina in silica,
have been synthesized by a hybrid sol–gel technique followed by subcritical drying. The …
