Understanding and developing new molecules in chemical sciences have been great thrust areas of research, not only to develop new synthetic methods or reaction mechanisms of new and greener experimental conditions but also to know what are the new molecule science and what are the new models which can track their new role in chemical processes and also their applications in allied interdisciplinary sciences. The SAR (structure-activity relationship) and STAR (structure-thermodynamics activity relationship) have been the most intimate theories in understanding and finding unique applications of the new molecules. Initially, simple molecules are the focus; however, proteins, hemoglobin, starch, and certain metallic complexes are also in the focus but as natural chemicals; but for past few decades, a lot of focus has been on synthesizing new complex molecules to make them suitable for varieties of applications such as solar, catalysts, biosensors, and others. Hence, it has been essential for focusing on structural sciences of the chemical substances. Dendrimers have been the invention of 1990s in the areas of biocomplexes, biomaterials which are hot thrust areas in molecular interaction engineering to focus on intramolecular potential for industrial applications. Thus, the molecule’s internal structure signifies the various scientific components for playing or making their best use in materials sciences, semiconductor, spintronics, photonics, electronics, etc. Therefore, the molecule’s interacting response with other molecules becomes cohesive or kinetic in nature or whether it induces structuredness or weakens the binding forces and allows more and more kinetic movement or the motion is noted or defined by friccohesity as it is expressed as frictional and cohesive forces. Thus, the friccohesity is a dual forces theory which deals with frictional and cohesive forces together and determined with Survismeter using Mansingh equation molecules [1–3].
