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 ...
