Symbiotic relationship, defined

A symbiotic relationship has been defined as a "mutually advantageous" relationship... 

The selection of the independent process parameters (which include the choice of specifications for the raw materials and intermediates) is made during development in an effort to ensure the appropriate response of the dependent parameters. The relationship between the independent and dependent variables need not be linear, and may be inverted. The key is to recognize that the selection of the independent variable influences the dependent variable. While this description is simplistic and ignores the possible influence of other variables, it accurately describes the symbiotic relationship between process and product. Without a process (as defined by the selection of the independent variables), there is no product (with its dependent product attributes). Without a product, there is no reason for the process. The PAR approach describes how one is to develop the relationship between the process and its resultant product. There is no reason to choose one over the other consideration and confirmation of both is necessary to validate a product. 

A facile route based on precursor chemistry has been emphasized with low cost, easiness and sustainability for technological applications. The evaluation of suitable molecular precursor plays a very important role to produce wide spectrum of nanopowder with high purity with well-defined properties without any contaminations. The application of nanopowder takes place with uniform size distribution of nanoparticles in the matrix with compatible dispersion. The success in nanoscience depends on the symbiotic relationship between the molecular chemistry and new materials. The synthesis of nanopowder with low energy consumption, convenient manipulation and large operational compatibility with controlled particle properties is still a challenge for synthetic chemists.
