Knowledge of surface free energies (and its components) between two entities is important. They dictate not only the strength of the interaction, but also control the processes such as the stability of aqueous colloidal suspensions, the dynamics of molecular self-assembly, wetting, spreading, deinking and adhesion (1-4). Many of the mineral processing techniques, e.g. froth flotation, selective...

Out of 12 fungal strains, two fungal strains, namely Aspergillus flavus AT-2 and Aspergillus niger AT-3, were found to produce maximum cellulase production. The CMCase activities of A. flavus AT-2 and A. niger AT-3 under state solid fermentation (SSF) conditions were of 42.69 and 40.08%, respectively, which was higher than those obtained under submerged fermentation (SmF) conditions. A fungal i...

Surfactants and polymers are two of the important components in detergent formulations. The interactions between polymers and surfactants in aqueous media give rise to the formation of association structures, thereby modifying the solution and interfacial properties. The morphologies of association complexes depend on the molecular properties of the polymer and the surfactant. In this paper, we...

The structure of the hydrophobe in alcohol ethoxylates (AE) and alkylphenol ethoxylates (APE) has a significant influence on the biodegradation pathways and biodegradation rates of these nonionic surfactants in bacterial inocula present in waste treatment plants. APE undergo initial microbial attack at the terminal part of the polyoxyethylene (POE) chain followed by a shortening of the POE chai...
