Significance of thermal diffusivity
WebAlso, an increase was observed in the release rates of amino acids as a result of higher hydrophobicity. The significant effects of hydrophobicity and temperature, as well as the constant enclosed water volume revealed that the release of amino acids from the inner to the outer water phase was mainly governed by a direct diffusion mechanism.
