Click grafting of seaweed polysaccharides onto PVC surfaces using an ionic liquid as solvent and catalyst.
Seaweed antibacterial polysaccharides were grafted onto poly(vinylchloride) (PVC) surfaces using an original click chemistry pathway. PVC isothiocyanate surfaces (PVC-NCS) were first prepared by nucleophilic substitution of the chloride groups by isothiocyanate groups in DMSO/water medium. Then, unmodified Ulvan, Fucan, Laminarin or Zosterin was directly grafted onto the PVC-NCS surface using 1...
متن کاملCellulose Nanofi brils: From Strong Materials to Bioactive Surfaces**
Cellulose nanofi brils (CNF), also known as nanofi brillar cellulose (NFC), are an advanced biomaterial made mainly from renewable forest and agricultural resources that have demonstrated exceptional performance in composites. In addition, they have been utilized in barrier coatings, food, transparent fl exible fi lms and other applications. Research on CNF has advanced rapidly over the last de...
متن کاملGrafting Hypersequents onto Nested Sequents
·Ve introduce a new Gcn(zen-style framework of grafted hypc1rsequents that com\Jim's the fornrnlism of nested sequents with that of hyperscquents. To illustrate the potential of the frmnework. we present novel calculi for the modal logics K5 and KD5, m; well as for extensions of the modal logics K and KD with tlw axiom for shift rdlcxivity. Tlw latter of these extensions is also known as SDL + ...
متن کاملImmobilization-stabilization of proteins on nanofibrillated cellulose derivatives and their bioactive film formation.
In a number of different applications for enzymes and specific binding proteins a key technology is the immobilization of these proteins to different types of supports. In this work we describe a concept for protein immobilization that is based on nanofibrillated cellulose (NFC). NFC is a form of cellulose where fibers have been disintegrated into fibrils that are only a few nanometers in diame...
متن کاملFacile synthesis of spherical cellulose nanoparticles
A practical procedure for synthesizing cellulose nanospheres with sizes ranging from 60 to over 570 nm was developed. This methodology provides a near linear relationship between cellulose nanoparticle size and treatment time. The hydrolyzed nanocelluloses are predominantly cellulose II polymorphic crystalline structure and relatively uniform in particle size. 2007 Elsevier Ltd. All rights rese...
