Polybenzimidazole-phosphoric acid membranes have been used extensively in high temperature fuel cell applications. They are generally prepared either by copolymerization of tetramines and dicarboxylic acids (AA/BB copolymers) or by homopolymerization

Alkylsilane-modified nanoporous ceramic membranes exclude water from their pores yet exhibit transmembrane electrical conductivity in aqueous electrolyte solutions. That effect was studied using impedance spectroscopy and (29)Si NMR. Anodic aluminum

Monitored natural attenuation (MNA), while a remedy of choice for many sites, can be challenging when the contaminants are chlorinated solvents. Even with many high-quality technical guidance references available, there continue to be challenges impl
