HYDROLYTIC DEGRADATION BEHAVIOR OF PLLA NANOCOMPOSITES REINFORCED WITH MODIFIED CELLULOSE NANOCRYSTALS

Química Nova, 2015
Bionanocomposites derived from poly(L-Lactide) (PLLA) were reinforced with chemically modified cellulose nanocrystals (m-CNCs). The effects of these modified cellulose nanoparticles on the mechanical and hydrolytic degradation behavior of polylactide ...

Gelation of cellulose nanocrystals

, 2020
Colloidal gels of cellulose nanocrystals (CNCs) were prepared using three different strategies by manipulating their colloidal stability. In the first approach, colloidal gels were prepared by hydrothermally treating CNC suspensions. Desulfation of the CNCs at high temperature appears to be responsible for the gelation of the CNCs, giving highly porous

Preparation of Porous MOF‐Polymer Composites via High Internal Phase Pickering Emulsions for Dye Adsorption Applications

Chemistry – A European Journal, EarlyView.
A versatile method was developed to fabricate hierarchically porous monoliths using UiO‐66/TOCNC composites as Pickering emulsion stabilizers. The resulting polyHIPEs, produced under mild and scalable conditions, showed confirmed structural integrity through TGA, XRD, SEM, BET, and FT‐IR.

Effects of polymorph transformation via mercerisation on microcrystalline cellulose fibres and isolation of nanocrystalline cellulose fibres [PDF]

, 2017
Cellulose I can be irreversible transformed into cellulose II via mercerisation or regeneration treatments. In the past few decades, mercerisation was used mainly to improve fibre properties for textile industries.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...
