Dynamics in poly vinyl alcohol (PVA) based hydrogel: Neutron scattering study

Prabhudesai, S.A.; Lawrence, M.B.; Mitra, S.; Desa, J.A.E.; Mukhopadhyay, R. (AIP Conference Proceedings. 1665; 2015; ArticleID_040020.)

Results of quasielastic neutron scattering measurements carried out on Poly Vinyl Alcohol (PVA) based hydrogels are reported here. PVA hydrogels are formed using Borax as a cross-linking agent in D sub(2)O solvent. This ...
Effect of Borax concentration on the structure of poly (vinyl alcohol) gels

Lawrence, M.B.; Desa, J.A.E.; Aswal, V.K. (AIP Conference Proceedings. 1447; 2012; 199-200.)

Poly(Vinyl Alcohol) hydrogels cross-linked with varying concentrations of borax have been studied using Small-Angle Neutron Scattering and X-Ray Diffraction. The intensity of scattering increases with borax concentration ...
Properties of poly(vinyl alcohol)-borax gel doped with neodymium and praseodymium

Lawrence, M.B.; Desa, J.A.E.; Aswal, V.K.; Rai, R. (Bulletin of Materials Science. 37(2); 2014; 301-307.)

The magnetic properties of the Mn3Ga(1-x)SnxC, 0 less than equal to x less than equalt to 1 antiperovskite compounds have been investigated in detail. Though all compounds of this series crystallize in a cubic structure, ...
Reentrant behaviour in polyvinyl alcohol-borax hydrogels

Lawrence, M.B.; Desa, J.A.E.; Aswal, V.K. (Materials Research Express. 5(1); 2018; Article ID 015315.)

Polyvinyl alcohol (PVA) hydrogels, cross-linked with varying concentrations of borax, were studied with Small Angle Neutron Scattering (SANS), X-ray Diffraction (XRD) and Differential Thermal Analysis (DTA). The SANS data ...
A small angle neutron scattering study of poly(N-isopropyl acrylamide) in water

Lawrence, M.B.; Desa, J.A.E.; Aswal, V.K.; Badiger, M.V. (AIP Conf. Proc. 1313. 2010; 373-375.)
Structural and Optical Studies of Polymer Solutions and Hydrogels

Lawrence, M.B.
Structural and spectroscopic properties of poly(vinyl alcohol)-borax hydrogels co-/doped with holmium and erbium

Lawrence, M.B.; Desa, J.A.E.; Francis, Sheetal; Phal Dessai, V. (Materials Research Express. 6(6); 2019; ArticleID_065319.)

Holmium and Erbium nitrates, singly and together, have been incorporated in a Poly(vinyl alcohol)-borax hydrogel matrix and studied with XRD, FTIR, DTA, swelling tests, UV-visible spectroscopy and photoluminescence. FTIR ...
A study of cross-linked regions of Poly(Vinyl Alcohol) gels by small angle neutron scattering

Lawrence, M.B.; Desa, J.A.E.; Aswal, V.K. (AIP Conf. Proc. 1349. 2011; 220-221.)

A poly(vinyl alcohol)-borax cross-linked hydrogel has been studied by Small Angle Neutron Scattering as a function of borax concentration in the wave-vector transfer (Q) range of 0.017 Angstrom sup(-1) to 0.36 Angstrom ...
