Chemically Fueled Autonomous Sol→Gel→Sol→Gel→Sol Transitions

Angewandte Chemie International Edition, 2023
AbstractComplex non‐equilibrium phase behaviors are a hallmark of natural self‐assembling systems. Here we show how intricate phase transitions can be achieved through a chemically fueled reaction cycle to yield autonomous sol→gel→sol→gel→sol transitions.

A Structural Comparison of Ordered and Non-Ordered Ion Doped Silicate Bioactive Glasses [PDF]

, 2020
One of the key benefits of sol-gel-derived glasses is the presence of a mesoporous structure and the resulting increase in surface area. This enhancement in textural properties has a significant e ect on the physicochemical properties of the materials.
