Method of immobilization of enzymes by entrapment within the microcavities of synthetic fibres.  1, record 1, English, - fibre%20entrapment

Record number: 1, Textual support number: 1 CONT

The term entrapment has been used to cover a range of immobilization techniques. O’Driscoll has chosen to distinguish between those methods, where a gel or membrane is formed around an enzyme by polymerization and those methods where the enzyme is retained in a preformed polymer by subsequent formation of a cross-linked network. Microencapsulation and fiber entrapment are clearly other examples of this immobilization technique.  3, record 1, English, - fibre%20entrapment

En dehors de l'équipe de DINELLI, en Italie, qui a préparé de nombreuses enzymes immobilisées par inclusion dans des fibres d'acétate de cellulose, les enzymes immobilisées à structure non membranaire se présentent sous forme de particules de taille, de porosité et de propriétés mécaniques très variables. Ce sont les caractéristiques de ces particules qui conditionnent la mise en œuvre. Le choix du support pourra être ainsi différent selon que l'on envisage l'emploi de ces systèmes à petite échelle ou dans un but industriel.  1, record 1, French, - inclusion%20dans%20des%20fibres

A urethane is formed from the reaction of an isocyanate with an alcohol. In general, polyurethanes are made using a diisocyanate, a low molecular weight diol(thermoplastic) and/or triol(cross-linked), and a polyether glycol or a polyester glycol. If the reagents are difunctional, a non cross-linked thermoplastic polyurethane will be formed; if the functionality of at least one of the reagents is greater than two, a cross-linked or three dimensional network will form. Cross-linked polyurethanes exhibit less mechanical creep than non cross-linked polyurethanes. The rubbery modulus of polyurethanes increases as the level of cross-linking is increased. Polyurethanes are diblock copolymers. They consist of hard segments(isocyanate and the chain extender rich areas) that act as physical crosslinks, and soft segments(polyether or polyester glycol rich areas).  3, record 2, English, - three%20dimensional%20network
