(e.g., ions) for promoting tissue repair or of activating biological pathways (e.g., favoring or orienting cell activity). Such compounds are referred to as “bioactive oxides.” This activity is directly related to features such as chemical composition (and relatedthermodynamic stabilityin body...
The number of ions in a compound depends on the structure of the compound and the oxidation states of the elements within the compound. An element's oxidation state is the number of electrons that an atom possesses or lacks relative to the number of protons in its nucleus. This determines t...
This type of classification made a clear distinction between other particles that used ionic bonding, but it was soon realized that the level of interaction between covalent and ionic bonds was not fully understood, so classifying things as molecules based on bond type was unwise. This has led t...
Ionic pounds have higher boiling and melting points. It is because ionic pounds made up of ions. They are held together by strong electrostatic (ionic) bond. For example in sodium chloride (NaCl)the Na+ ions are attracted to the Cl- ions. Because of the strong attraction forces...
of positive and negative ions in chemistry. The formula KBr shows that it is made up of one unit of potassium in the form of potassium cation {eq}K^{+1} {/eq} and one unit of bromine in the form of bromide anion {eq}Br^{-1} {/eq}, making it an inorganic metal bromide salt....

Beyond this, the lithiation/delithiation process was explained by a possible mechanism of conductivity balance between electrons and ions. It was suggested that the Si particles (∼50 nm) did not shift in the discharge-charge process because the Li+ ion (∼2 Å) is too small to ...

The pH of the electrolyte and/or the concentration of ions of the inserted species must be sufficiently high to provide stability for the product compound. The method is useful for further lithiation of conventional lithium ion battery cathode materials....
reported the removal of Pb2+ ions from aqueous solutions by using synthetic polymer P(AO/AN/MA) which achieved an adsorption capacity of 4.28 mmol/g at 25 °C [241]. Polymers which could selectively adsorb metal ions should consist of two monomer groups, each having a different role. One...
