This everolimus more clearly seen in the textural parameters obtained from the adsorption isotherms compiled in Table 3. Overall, the prepared samples present lower values of surface area and micropore volumes compared to N-free RF aerogels obtained from similar procedure, due to the zone of intolerance incorporation of melamine in the reactants mixture .
