Molecular assemblies in bulk and at oil-water and air-water interfaces are key phenomena widely employed for many applications. This volume presents recent advances in this field relevant to diverse applications such as drug and nucleic-acid delivery, rheological control to facilitate oil thickening, stability of emulsions, formation of hydrogels, stability of latex dispersions, topical creams, food emulsifiers, chemical separations and catalysis, and responsivefunctional materials. Readers will benefit from an overview of the research frontier, gain a fundamental understanding of self-assembly at the molecular scale, and appreciate connections to the diversity of industrial applications.
