Characterization of monolithic porous carbon prepared from resorcinol/formaldehyde gels with cationic surfactant

Nanostructured mesoporous carbons: Tuning texture and surface chemistry

“…In terms of industrial scalability, evaporative drying without any preliminary treatment is obviously the most attractive drying procedure due to its simplicity and low-cost. It was recently discovered that the use of cationic surfactants during synthesis stabilizes the pore structure during solvent [32][33][34]. Hence, surfactants adsorb on the hydrogel reducing the interfacial tension and preventing collapse of the pores during water removal.…”

Sol–gel simulation—I: Scattering response

“…Thus, using the recursion in Eqs. (21) and (22), the scattering intensity can be found for any structure, percolated or not.…”

“…Only the scattering function S(q) is required to calculate the scattering intensity for any value of q using Eqs. (21) and (22).…”

“…This technology uses colloidal aggregation [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27], which after the removal of the liquid phase leaves a solid ceramic structure [28,12]. Extracting the liquid phase of the colloid gently, e.g.…”

Sol–gel simulation—II: Mechanical response

“…Sol-gel technology, using colloidal aggregation, provides an efficient, green-manufacturing path for the fabrication of ceramic products [1][2][3][4][5][6][7][8][9][10][11][12][13]. Dense films, aerogels, supercapacitors, and dense ceramics, to name some, are manufactured with this technology [14][15][16][17][18][19][20][21][22].…”
