Hydrodynamics Involving Molecular Polymers Diagnosis Via Spectroscopy

The team examining how a solution of dissolved polymers changed after the addition of Fe3+ solution. These types of solutions are used to better control variables in several fields; including manufacturing. In automobile manufacturing, for instance; the solutions help achieve a thorough evenness of paint coverage; and control over how much a material expands or contracts under various temperatures.

Traditionally, researchers examine a solution before a reactant; such as Fe3+ solution, is adding, and again after the reaction takes place; In other words, if a fluid property such as the viscosity of the solution is higher after the reaction than before; study would expecting; that an increase in viscosity occurs from the reaction during flow; said Yuichiro Nagatsu; corresponding author on the paper; and an associate professor in the Department of Chemical Engineering at Tokyo University of Agriculture and Technology.

Study observing an increase in viscosity in the solution during a chemical reaction to Fe3+; but the solution had thinned back out by the end of reaction. They confirming their chemical observations with infrared spectroscopy; which allowing researchers to examine microscopic interactions without extensive preparation; that could further disturb the sample.

But flow dynamics account for microscopic changes within these chemical reactions; molecules stripping other molecules of electrons and the like; that fundamentally change the composition of the solution. However, viscosity is known as a macroscopic change it describing the solution; as a whole rather than the individual interactions on the microscopic level. It is incredibly unusual for such a solution to shift through such macroscopic phases only to lose the characteristics by the end of a chemical reaction; according to Nagatsu. This understanding could have major implications across industrial; environmental, and biological fields.

Our ultimate goal is to establish a new research area to understanding chemically reacting flow; involving the diagnosis of molecule structure,” Nagatsu said. Study also noting that the plans to develop a novel method to control fluid dynamics through their new understanding of interactions.
