Carboxylated nanocellulose from quinoa husk for enhanced protease immobilization and stability of protease in biotechnological applications by Shohreh Ariaeenejad, Elaheh Motamedi

“…For chemical immobilization, CNCs were firstly functionalized with N, N′-dicyclohexylcarbodiimide (DCC) to provide DCNCs nanocarrier which could covalently bond to enzyme trough nucleophilic substitution reaction and formation of the amide bond between DCNCs and enzyme. The immobilization efficiency, activity, stability, kinetic parameters, and reusability of covalently attached and physically immobilized PersiProtease1 were similar to those of the free enzyme. …”

Modification of polymers to synthesize thermo-salt-resistant stabilizers of drilling fluids by Artykova Zhadyra, Beisenbayev Oral, Issa Aziza, Kydyraliyeva Aigul

“…The results indicate that the optimal ratio of acrylonitrile to vinyl sulfonic acid is 80:20 at pH 3–6, which, combined with hydrolysis and modification, produces composite multifunctional polymer stabilizers with amide, imide, carboxylate, and sulfonic groups. These stabilizers exhibit enhanced hydrophilicity and an amorphous structure, making them effective for use in extreme drilling conditions. …”
