The optical and rheological properties of aqueous solutions of block copolymer composed of low molecular weight poly(N-isopropylacrylamide)-b-polystyrene are studied as a function of temperature. From light scattering measurements the block copolymer

We report here, an evidence of entanglements between polymer chains of thermo-responsive microgels with the immobilizing hydrogel, by studying the temperature dependent dynamics of the microgel-hydrogel composite. The dynamics measurements show a dec

Aqueous suspensions of sub-micron sized monodisperse particles exhibit structural ordering analogous that observed in atomic systems. Deionised suspensions of colloidal charged polystyrene particles exhibit long-range order for volume fraction ɸ> 0.

Aqueous suspensions of thermo responsive poly (N-isopropyl acrylamide) (PNIPAM) microgel particles exhibit volume phase transition (VPT) around 34°C. PNIPAM microgel spheres are known to be core-shell type having a dense core and a fuzzy shell of da

In this paper we investigated the effect of quaternary ammonium bromide, R4NBr(R = methyl, ethyl, propyl, butyl) on the micellization of the CTAB/long-chain alcohol (C9OH-C12OH) micellar system using viscosity, rheology, dynamic light scattering (DLS

Poly(N-isopropylacrylamide) (PNIPAM)-based microgels respond to temperature and exhibits a transition from swollen to deswollen state upon variation of temperature, which is known as volume phase transition (VPT). Dynamic light scattering (DLS) is a

Holographic Optical Tweezers (HOTs) employ the technique of beam shaping and holography in an optical manipulation system to create a multitude of focal spots for simultaneous trapping and manipulation of sub-microscopic particles. The beam shaping i
