Protonation constants of a viral inhibitor, aurintricarboxylic acid were determined using potentiometric method of data acquisition followed by chemometric modelling methods of analysis in the presence of two different kinds of micellar media, CTAB, a cationic micelle and SDS, an anionic micelle. MINIQUAD75 program was used for the determination of the plausible species and their corresponding formation constants at 303 ± 0.1 K and 0.01 M ionic strength. Five formation constants were identified corresponding to five ionizable hydrogens. Species concentration distribution diagrams were generated using Origin software. Best-fit chemical models were selected on the basis of statistical parameters like standard deviation (SD), U (sum of the squares of the residuals in mass balance equations) and chi-square test. It was found that the formation constants are lower in CTAB micellar medium while there is no significant change in the presence of SDS compared to aqueous medium.

A non-thermal dielectric barrier discharge (DBD) plasma reactor was integrated with M/SBA-15 (M = Pd, Pt, Ag and Au) catalyst, where the metal reduction was achieved by H2 plasma. Later,...

An NTP hybrid system was designed in combination with metal oxide (MOX) coated glass beads (GB) to synthesize value-added fuels and chemicals from methane directly. The combined plasma-packed mode was...
