Measurement of oxygen diffusion in PS/PNIPAM films using fluorescence quenching
(Taylor & Francis Ltd, 2015)
The diffusion of oxygen into pyrene labelled polystyrene (PS) latex/poly(N-isopropylacrylamide) (PNIPAM) composite films (PS/PNIPAM) was studied based on PS content with the use of fluorescence quenching method. Fluorescence ...
Thermal Phase Transitions of IOTA Carrageenan in CaCl2 Solutions: A Fluorescence Study
(Taylor & Francis Inc, 2011)
The fluorescence technique was employed to study thermal phase transitions of iota (-) carrageenan (IC) in CaCl2 solution. IC gels underwent coil to double helix (c-h) and double helix to dimer (h-d) transitions upon ...
Thermal Phase Transitions of Agarose in Various Compositions: A Fluorescence Study
(Springer/Plenum Publishers, 2011)
The effect of agarose content on thermal phase transitions of the agarose gels was investigated by using Steady State Fluorescence (SSF) method. Scattered light I(sc) and fluorescence intensity I(fl) were monitored against ...
Gelation of PAAm-PVP composites: A fluorescence study
(World Scientific, 2014)
Hybrid hydrogels are a new class of composite materials. Polyacrylamide (PAAm) hydrogels are mainly produced by free radical crosslinking copolymerization (FCC) of AAm in the presence of N N'-methylene bis (acrylamide) ...
Sorption and Desorption of PVA-Pyrene Chains in and out of Agarose Gel
(Springer/Plenum Publishers, 2012)
In situ steady-state fluorescence (SSF) measurement technique was applied to investigation of pyrene labeled Poly(vinyl alcohol) (PVA-Py) molecules diffusion in and out of agarose gels. Gel samples with four different ...
Optical and mechanical properties of PNIPAm-MWCNTs and PNIPAm-GO composites
(Wiley, 2023)
The aim of this study is to investigate drying, swelling, elastic properties, and to produce optical band gap energies on the performance of Poly (N-Isopropyl acrylamide) - Multi walled carbon nanotubes (PNIPAm - MWCNTs) ...
