What is it about?
Changes of networks and structures of water during coagulation processes have been clarified by full atomistic molecular dynamics simulations.

Why is it important?
Because of large size difference of colloidal particle and water, studies of colloidal chemistry tends to be performed by neglecting details of solvent. Systematic studies by full atomistic simulations enable us to understand how gel is formed in microscopic level.
Perspectives
With formation of gel in silica-nanocolloid-water-NaCl systems, changes in structure of water is found. With this change, dynamics of water also changes. Therefore, role of solvent in coagulation process should be considered in details.
