We previously reported the synthesis of nine derivatives of acid dyes using substituted aryl amines as diazo component and amino-hydroxy substituted naphthalene sulfonic acid as coupling component [14].
Although the antimicrobial efficacy of these polymers is progressively diminished through complexation of sulfonic acid groups with cationic species during cyclic exposure to electrolyte solutions, these thermoplastic elastomers can be fully rejuvenated to their maximum performance level by relatively short immersion in acidic solutions.
As expected, pure PANI had the lowest activation energy, and the values increased with increasing concentrations of CSA in the blends, confirming the attachment of sulfonic acid groups to the electrons of the NH groups, which was noted above.
Perfluorooctane sulfonic acid is a potent inducer of peroxisomal fatty acid b-oxidation and other activities known to be affected by peroxisome proliferators in mouse liver.

This result suggests that, as more sulfonic acid sites are incorporated into the membrane structure, the proton conductivity is decreased.
Tersperse(r)2700 (a dispersant), 1-naphthalene sulfonic acid, sodium salt (a wetter), lignosulfonic acid, sodium salt (a dispersant-cum-binder), sodium acetate (a disintegrant), sodium alginate and sodium glutamate (as nutritive sources as well as protectant) were selected as basic components of a WG-conidia formulation as they were not harmful to MPs with germination beyond 80%, when conidia was exposed to these additives (Table 4).
Sulfonic acid functionalized nano-[gamma]-[Al.sub.2][O.sub.3] was easily prepared by the reaction of nano-[gamma]-[Al.sub.2][O.sub.3] with 1,3-propanesultone (Scheme 2), and it was characterized by FT-IR, Xray powder diffraction (XRD), thermogravimetric analysis (TGA), and transmission electron microscopy (TEM).
The slow phenol liquefaction rate of pine bark with mineral acid catalysts, such as SA or hydrochloric acid, especially at low phenol-to-bark ratios, has led to investigation of various organic sulfonic acids, such as methane sulfonic acid, naphthalene sulfonic acid, benzene sulfonic acid, and p-toluene sulfonic acid (PTSA), and a markedly higher effectiveness was reported in comparison with SA catalyst (Mun et al.
FDA thus concluded that homotaurine is not an "amino acid" under Section 201(ff)(l)(D) because it is a gamma-amino sulfonic acid, and not an alpha-amino carboxylic acid or a constituent of proteins.
Due to synergistic effect, the ATBS-modified PUD is expected to exhibit the benefits of both the systems and presence of sulfonic acid groups would result in a strong polyelectrolyte character.
