swelling kinetics

A series of gelatin-based hydrogels was prepared, and the effects of different crosslinking agents and agar content were studied in detail. Results indicate that borax and glutaraldehyde are good crosslinking agents. Moreover, all samples were described with a hindered Fickian water diffusion, making it an interesting choice for medical applications.

One of the priorities of modern construction industry is to increase the heat-shielding properties enclosing structures and reduce construction costs. Solving these problems is possible through the use in the manufacture of insulating exterior walling and structuralinsulating non-autoclaved aerated concrete from technogenic waste, especially fly ahes and slag thermal power plants.
