Abstract:
Textural properties of carbon xerogels and their applications depend on the path of synthesis. The variables to be considered are the starting reagents, relation and the catalysis medium used. Here we present a dataset for a series of carbon xerogels obtained by the polymerization of resorcinol-formaldehyde (R/F) at different resorcinol/Na2CO3 (C) ratios (R/C). To examine the effect R/C ratio on the morphology and surface chemistry of the xerogels, N2 isotherms at 77K, XRD, FTIR were measure as well as of immersion calorimetry measurements were taken in water and benzene; point zero charge (pzc) were also determined. These results are reported here.

Basicity of Aliphatic Amines
To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates higher...
Basic Operations on Signals
Time Reversal mirrors a continuous-time signal about the vertical axis at t=0. This is achieved by substituting t with −t. For example, if a signal x(t) is considered, the time-reversed signal is x(−t). This operation can be graphically represented, showing the mirrored signal.
