Abstract-
Anisotropic colloids are nowadays widely used to modify the rheological properties of liquids in applications such as cosmetics, paints, and inks so understanding its flow properties and aging behavior is of considerable practical as well as fundamental importance. It is important to have a thorough understanding of the stabilization mechanism of colloidal particles in room temperature Ionic Liquids (ILs) which have some potential applications in enzyme-free sensing. A significant conclusion is drawn for the aggregation kinetics, slow dynamics, and differential hydration in ionic liquids induced gelation in colloidal gels. Also, the aqueous dispersion of mixed colloids was found to exhibit a range of soft matter phases that evolved with waiting time and colloid/IL concentration. Thus, concentration dependent hierarchical self-assembly, ergodicity breaking and aging dynamics for mixed cogels have been studied extensively. The electro-catalytic behavior of these structurally better and functionally advanced materials so produced find their applications in the construction of enzyme-free sensors for the detection of different metabolites present in human body such as ascorbic acid, oxalic acid, urea, citric acid, glucose and cholesterol.
Additionally, taking into consideration the wide application of freeze-thaw polymer gels, the rheological behavior of the aqueous solution of polymer hydrogel is undertaken and the motive is to comprehend the mechanism of sol to gel transition using rheology; rendering keen insights into the macroscopic behavior of structured systems in terms of their underlying microstructure. These findings could hold the potential to revolutionize the rheological investigation of polymeric gels and can pave for the development of futuristic applications.
All are cordially invited to attend the Talk.
