An analysis of isotherms reveals that Freundlich isotherm is unsuitable to describe monolayer adsorption. To rectify it, the constant k of the equation can be replaced by a pressure dependent parameter. A method has been depicted to find out pressure dependent values of k and n from experimental results.
A new insight has been introduced into the interaction mechanisms of a chain molecule at a liquid-liquid interface. The theory of rubber elasticity has been incorporated to understand the whole process of interaction.
The promising aspects of dendrimers and some other nanoparticles like nanoceria (a nanozyme) and quantum dots (including carbon dot, a quantum dot of size below 1 nanometer) have been discussed. Their emerging uses in treating ailments, sensing devices, modern electronic goods, and in boosting green technologies have been discussed briefly.
Future studies of surface science will largely depend on the uses of quantum computers. They will reduce both cost and time of experiments and at the same time will provide more accurate or otherwise incalculable data.

The hyperbranched spherical monodisperse polymeric macromolecules known as dendrimers, although they are the latest additions to polymers, are finding many applications in the areas of biology, biotechnology, medicine, catalysis, and in nanoreactors, and has emerged as a class of materials with one of the fastest growing areas of research and applications. Certain areas related to this finer aspects of molecular architecture, molecular dynamics under the influence of shear force and in solution, precise thermal behavior have still not been understood precisely. In this paper some thoughts have been suggested for further research to exploit them in a most helpful manner.Keywords
