The acid-base character of the surfaces of commercially available carbon fibers used in advanced composites is determined using both pulsed and continuous flow microcalorimetry techniques. The carbon fibers investigated include unsized versions of AS4, IM6, IM7X, T300, and several Apollo fibers with ...

Presentations of aromaticity and acid-base character of pyridine and pyrrole in 18 contemporary organic chemistry textbooks were surveyed. Superficially, each of these two monoaza aromatic heterocycles retains an electron pair on its sp-hybridized ring nitrogen, ostensibly available for neutralization with...
The results show a basic character for treatment times lower than 1 s. This property disappears for longer treatment times showing less specific interaction sites accessible at the surface. These results are confirmed by ToF-SIMS and are in agreement with wettability studies and adhesion phenomena ...

What is determining during the system formation is the acid-base character of the interaction between the separate compounds. Such an interaction develops not only within each phase of the system, but also on the interfaces. Such a concept must be applied to polymer formation in the presence of...
It was found that the acidity (basicity) of the Cu1−xCoxFe2O4 spinel system increases (decreases) from x=0 to 1. A correlation between acidity, basicity and catalytic performance reveals that an intermediate acid–base character enhances the phenol methylation activity. 展开 ...
Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems. Their importance becomes apparent in analyzing acid–base reactions for gaseous or liquid species, or when acid or base character may be somewhat less apparent. The ...
