recommendations! Published in 2020 at "Journal of Inorganic and Organometallic Polymers and Materials"

DOI: 10.1007/s10904-020-01487-9

Abstract: Six new N,N,O tridentate water soluble hydrazide based O-carboxymethyl chitosan Schiff base derivatives have been prepared through in-situ synthesis. The degree of substitution of schiff base derivatives was calculated theoretically and the derivatives were prepared… read more here.

DOI: 10.1016/j.ijbiomac.2021.06.105

Abstract: Taking the advantage of multifunctional characteristics of chitosan (CS), we have developed new scaffolds (imidazolium-vanillyl-chitosan Schiff bases (IVCSSBs)) for supporting Pd(II) and Ru(II) ions in catalyzing Suzuki coupling reactions. The structures of new materials were… read more here.

DOI: 10.1016/j.ijbiomac.2022.01.151

Abstract: A novel modified chitosan Schiff base@Fe2O3-NiFe2O4 (CsSB@Fe/NiFe) was prepared and characterized using FT-IR, XRD, SEM, EDX, TGA, DSC and VSM. FT-IR and XRD results confirm that the nanoparticles of Fe/NiFe distributed throughout the surface of… read more here.

DOI: 10.1016/j.polymertesting.2019.106244

Abstract: Abstract Chitosan Schiff bases (CSBs) decorated with ammonium or pyridinium motifs for recyclable biosorption of Cu2+ ions from aqueous effluents were tailored by grafting of salicylaldehyde ionic liquids (Sal-ILs) onto chitosan surface. Biosorption capacity of… read more here.

DOI: 10.3390/polym15040980

Abstract: A new series of hydrogels was successfully prepared by incorporating various substituted bisuracil (R-BU) linkages between chitosan Schiff’s base chains (R-BU-CsSB) and between chitosan chains (R-BU-Cs). After protection of the amino groups of chitosan by… read more here.
