6 天之前 · The sol-gel transition of gelatin aq. solns. was studied by dynamic light scattering as a function of gelatin concn., C, at 10°, by taking account of the nonergodic nature of gels. The sol-gel transition concn., Cgel, is ∼0.35% in this particular case. The scattered intensity exhibited a speckle pattern for C > Cgel.

2021年12月24日 · The sol-gel method is a conventional and industrial method for the synthesis of nanoparticles with different chemical composition. The basis of the sol-gel method is the production of a homogeneous sol from the precursors and its conversion into a gel. The solvent in the gel is then removed from the gel structure and the remaining gel is dried.

2021年12月1日 · The colloidal sol-gel is a well-established method for the synthesis of nanoparticles with high reproducibility, homogeneity and low cost. It is a versatile route which allows synthesising many ceramic materials at the nanometric scale.

Sol-gel reactions promote the growth of colloidal particles (sol) and their subsequent network formation (gel) through the hydrolysis and condensation reactions of inorganic alkoxide monomers.

Isol-Gel est un gel élastomère de silicone souple, non-toxique, adhérent et transparent, à usage général, conçu pour les applications électroniques et électriques. Il est destiné à être coulé dans un support (ex : boîte de dérivation,…).
