Chemical cross linking versus high energy electron beam cross linking of HDPE: electrical properties study
Cross linking of high density polyethylene (HDPE) was first performed via high energy10 Mev electron beam (EB) irradiation. HDPE was also cross linked withDicumyle peroxide (DCP).The gel content of samples was determined by solvent extraction.Degree of cross linking was evaluated by hot set apparatus; as well .In order to clarify the effectof nature of cross linking, correlation of electrical p...
متن کاملCyclodextrin tetraplexes: first syntheses and potential as cross-linking agent.
The first syntheses of two cyclic tetramers of cyclodextrins, dubbed tetraplexes, are described as well as the use of one of them to form a supramolecular assembly with a modified biopolymer.
متن کاملBonding corneal tissue: applications of photoactivated diazopyruvoyl cross-linking agent.
Photoactivated bis-diazopyruvamide-N,N'-bis(3-diazopyruvoyl)-2,2'-(ethylenedioxy)bis-(ethylamine), (DPD)-was previously shown to bond materials containing type I collagen. However, tensile strength of bonded collagenous tissue ( approximately 78% water) was low compared with that of dehydrated collagenous gelatin ( approximately 14% water). Here we investigated the role of water in corneal tiss...
متن کاملLaccase-Based CLEAs: Chitosan as a Novel Cross-Linking Agent
Laccase from Coriolopsis Polyzona was insolubilized as cross-linked enzyme aggregates (CLEAs) for the first time with chitosan as the cross-linking agent. Concentrations between 0.01 and 1.867 g/L of chitosan were used and between 0.05 and 600 mM of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride. The laccase was precipitated using ammonium sulphate and cross-linked simultaneously. ...
متن کاملcollagen cross-linking
patients with keratoconus constitute a large proportion of patients suffering from anterior segment disorders. as of this time, however, its pathogenesis has not yet been elucidated. a reduction in cross-link between collagen molecules has been observed in keratoconic eyes as compared to normal ones. present approaches only address refractive errors resulting from the abnormal abnormal corneal ...
