Values for ionic radius are difficult to obtain and tend to depend on the method used to measure the size of the ion. A typical value for an ionic radius would be from 30 picometers (pm, and equivalent to 0.3 Angstroms Å) to 200 pm (2 Å).Ionic radiusmay be measured using ...
stable electronic configurations. The resulting ions of opposite charge have a strong force of electrostatic attraction, which is called an ionic bond.Note:This bond forms through the complete transfer of electrons from one atom to another, in contrast to the electron sharing of the covalent bond....

These include covalent bonding of chemical groups onto the π-conjugated skeleton of CNMs, non-covalent adsorption or covering with several functional molecules and endohedral filling of their empty inner cavity [163]. The covalent modification of CNMs can be of two types, i.e., on the sides ...
While the surface of calcium cross-linked alginate hydrogel is highly hydrophilic and prevents direct cell attachment, the covalent derivatization of carboxylic group of alginate with RGD peptides provides excellent attachment to integrin receptors of cells [8,12]. Easy biodegradation of alginate ...
