Mesoporous organosilicas functionalized simultaneously with both pendant amine groups and ethylene/phenylene bridges, were synthesized to evaluate the effect of the bridges incorporated in the silica framework on the structure, porosity and adsorption properties of final materials. It turned out that the presence of the bridges enhanced the formation of porosity but adversely affected the efficiency...
The basis of the obtained materials was 95% (wt%) tungsten carbide with the addition of about 4.75% Co 0.1% Nb and 0.15% Tl. During sintering flake graphene was added and in the case of the second sample also nano diamonds were added into the top layer. Surface properties of the obtained materials were determined by wettability. The apparent surface free energy was described applying the hysteresis...
