New study explores amino acid that turns into gel in water

Hydrogels, ubiquitous materials in our daily lives, are the focus of scientific research published in Chemistry—A European Journal. Conducted by the SupraBioNanoLab at the Department of Chemistry, Materials and Chemical ...

Mimicking a bird's sticky spit to create cellulose gels

Using a small bird's nest-making process as a model, researchers from North Carolina State University have developed a nontoxic process for making cellulose gels. The freeze-thaw process is simple, cost-effective, and can ...

A low-tech way to create high-tech materials

AMOLF researcher Christiaan Van Campenhout has found a new, simple method to create a material with a regular pattern of crystalline bands. The pattern formed by the crystals is not a coincidence.

Gel

A gel (from the lat. gelu—freezing, cold, ice or gelatus—frozen, immobile) is a solid, jelly-like material that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state. By weight, gels are mostly liquid, yet they behave like solids due to a three-dimensional cross-linked network within the liquid. It is the crosslinks within the fluid that give a gel its structure (hardness) and contribute to stickiness (tack). In this way gels are a dispersion of molecules of a liquid within a solid in which the solid is the continuous phase and the liquid is the discontinuous phase.
