Gels is an international, peer-reviewed, open access journal on physical and chemical gels, published monthly online by MDPI. Open Access — free for readers, with article processing charges (APC) paid by authors or their institutions. On distingue deux grandes familles de gels : les gels chimiques et les gels réversibles.
Pour les gels chimiques, les points de réticulation sont formés par réaction chimique pour constituer le milieu « solide ». Celui-ci ne peut être dissous que par dégradation. Gels are mostly liquid by mass, yet they behave like solids because of a three-dimensional cross-linked network within the liquid. It is the cross-linking within the fluid that gives a gel its structure (hardness) and contributes to the adhesive stick (tack).
gels for triathlon, Gels are colloids (aggregates of fine particles, as described above, dispersed in a continuous medium) in which the liquid medium has become viscous enough to behave more or less as a solid. Gels are materials composed of a three-dimensional crosslinked polymer or colloidal network immersed in a fluid. They are usually soft and weak, but can be made hard and tough.

This property of gelatine led to the name we still use for these materials today: gels.
gels for triathlon, This term was coined by Scottish chemist Thomas Graham in the 19th century. En masse, les gels sont principalement constitués de liquide, mais ont un comportement proche de celui des solides grâce à leur réseau tridimensionnel enchevêtré au sein du liquide. Ce sont ces enchevêtrements qui donnent aux gels leur structure et contribuent à leur adhérence.
