تعريف cross-linking في الإنجليزية الإنجليزية القاموس.
The abnormal linking of two strands of DNA by covalent bonds (as opposed to the normal hydrogen bonds between base pairs), which can occur by exposure to X-rays Such linking is a type of damage to the DNA molecule and must be repaired before the DNA can replicate and function properly again
occurs when primary valence bonds are formed between separate polymer chain molecules
the setting-up of chemical valence links between the molecular chains of polymer molecules, leading to the formation of a 3-dimensional network of polymer chains which is infusible and insoluble This usually reduces the thermoplasticity of the material
an oxidation reaction in which indesirable bonds form between nucleic acids (RNA and DNA, the genetic blueprint material) or between proteins, often as links between sulfut atoms called disulfide bonds, or between lipids or any combination thereof The links may be between different proteins or nucleic acids or lipids or between parts of the same protein or nucleic acid or lipid The result is that the molecule cannot assume the correct shape for proper functioning Some cross-links are required in proteins for rigidity and structural strength However, cross-links of an inappropriate, undesired nature form throughout life
the formation of chemical bonds between polymeric chains to yield an insoluble, three dimensional polymeric structure Cross-linking of rubber is referred to as vulcanization or "curing "
The chemical bonding of molecules which in polymers occurs in the curing transition from a liquid to a solid
The setting up of chemical valence links between the molecular chains of polymer molecules, leading to the formation of a 3-dimensional network of polymer chains which is infusible and insoluble This usually reduces the thermoplasticity of the material
A process in which bonds are formed joining adjacent molecules At low density, these bonds add to the elasticity of the polymer and at higher densities, eventually produce rigidity in the polymers
Reacting together large molecules to change the physical properties of material Cross-linking involves formation of a three dimensional molecular network with thermosetting resins
A process in which bonds are formed joining adjacent molecules At low density, these bonds add to the elasticity of the polymer and at high density eventualy produce rigidity in the polymer
The establishment of chemical bonds between polymer molecule chains It may be accomplished by heat, vulcanization, irradiation or the addition of a suitable chemical agent
joining of two polymer chains which increases the strength of the polymer network (Chemistry); abnormal joining of two DNA strands by covalent bands (Molecular Biology)
Definition: The act of linking to content contained on a web site from elsewhere in that web site Examples: Linking each page of your web site back to the home page is an example of cross linking
The setting up of chemical links between molecule chains This occurs in all thermosetting resins Styrene monomer is a crosslinking agent in polyester resins
The setting up of chemical links between the molecular chains of a resin to form a three-dimensional network polymer system Crosslinking generally toughens and stiffens coatings
Quality of thermosetting plastic resins in which polymer chains combine during the curing process In general, the greater the crosslinking, the tougher and more chemically resistant the coating
