English

Subject field(s)
  • Biochemistry
  • Silk (Textiles)
  • Biotechnology
DEF

A principal organic constituent of raw silk, which is classed as a protein composed of several amino acids.

CONT

Fibroin has been widely used to produce materials for medical applications.... Typically, the fibroin is extracted from the silkworm cocoon by removal of sericin... and is then purified... The relative ease with which silk proteins can be processed in water or various solvents to form gels, fibers, or sponges with different chemical functionalization, together with their excellent biocompatibility, enzymatic degradability, and mechanical resilience, make these proteins interesting candidates for many biomedical applications...

French

Domaine(s)
  • Biochimie
  • Soieries
  • Biotechnologie
DEF

Protéine sécrétée par le ver à soie, qui durcit à l'air, et constitue la fibre de soie.

CONT

La caractéristique la plus importante de la fibroïne est sa teneur élevée en acides aminés carboxyliques simples tels que la glycine, l'alanine et la sérine.

Record 2 2016-02-26

English

Subject field(s)
  • Industrial Techniques and Processes
  • Plasma Physics
  • Chemical Engineering
CONT

Plasma surface treatment is extremely versatile and used in a range of industries. It can enhance biocompatibility, prevent moisture absorption through hydrophobic treatments, and it improves functionalization and adhesion-all from a value-driven, green alternative to harsh chemical techniques. It even extends treatment lifetime from days to years.

Key term(s)
  • plasma treatment of surfaces

French

Domaine(s)
  • Techniques industrielles
  • Physique des plasmas
  • Génie chimique
CONT

Traitement de surface par plasma - Dans l'industrie, on fait appel aux traitements plasma pour l'amélioration et le contrôle fin des propriétés de surface des matériaux : revêtement, nettoyage, activation, gravure... Lorsqu'une pièce est au contact d'un plasma, un film se forme à sa surface. Les molécules présentes dans la phase gazeuse conditionnent la nature du film formé. Les procédés plasmas sont des hautes technologies industrielles qui permettent le traitement de surface à haute performance et à haute valeur ajoutée de tous types de matériaux : métaux, plastiques et élastomères, verres, céramiques, composites, textiles, etc.

Record 3 2016-02-26

English

Subject field(s)
  • Industrial Techniques and Processes
  • Plasma Physics
  • Chemical Engineering
CONT

Plasma activation(or plasma functionalization) is a method of functionalizing a surface by means of plasma processing. It is done with the intent to alter or improve adhesion properties of surfaces prior to coating, painting, etc.

Key term(s)
  • plasma functionalisation

French

Domaine(s)
  • Techniques industrielles
  • Physique des plasmas
  • Génie chimique
DEF

Augmentation de l’énergie de surface par enlèvement de contaminants sur la surface ou par réaction chimique avec celle-ci.

OBS

Dans de nombreux cas, une activation est nécessaire avant l'étape suivante de revêtement afin d'améliorer la mouillabilité et l'adhésion du revêtement.

Record 4 2013-06-17

English

Subject field(s)
  • Industries
DEF

The naturally occurring nano-objects that are processed in some way prior to supply to a customer or inclusion in a product.

OBS

Such processing could include chemical treatment(e. g. functionalization), physical treatment(e. g. thermal treatment) or mechanical treatment(e. g. high shear rate mixing). Processing that is intended to concentrate the number density of nano-objects is also included.

OBS

processed nano-object: term and definition standardized by the International Organization for Standardization (ISO).

Key term(s)
  • processed nanoobject

French

Domaine(s)
  • Industries
DEF

Nano-objet d'origine naturelle qui fait l'objet d'une certaine transformation avant fourniture au client ou inclusion dans un produit.

OBS

Cette transformation peut comprendre le traitement chimique, par exemple la fonctionnalisation, le traitement physique, par exemple le traitement thermique, ou le traitement mécanique, par exemple le mélange à cisaillement élevé. Elle comprend également les traitements destinés à concentrer la densité numérique des nano-objets.

OBS

nano-objet transformé : terme et définition normalisés par l'Organisation internationale de normalisation (ISO).

Key term(s)
  • nanoobjet transformé
