The coordination of such molecules is directed by non-covalent bonds such as hydrogen bonds or electrostatic bonds. Combining with such complex physicochem- ical phenomena, formation of reliable self-assembly building structures, susceptibility of solution pH and ionic constituents to metal oxide ...
Hematite structure resembles corundum, in which the Fe3+ cations are connected to the octahedral oxygen via the covalent bonds in a hexagonal closed packing crystal system [4]. Hematite was reported to have high adsorption performance and stability, and to be easy and cheap to synthesize [1,6...
These polymers facilitate the formation of both covalent and non-covalent chemical bonds, thereby overcoming the limitations of other materials in terms of cell adhesion and cellular attachment [7]. Collagen (CG) is a protein that plays a pivotal role in the maintenance of the ECM. It is one...
The crystalline regions of POM/α-Fe2O3 provide a stable matrix where ions can move through well-defined channels, reducing resistance and enabling smooth ionic transport. Moreover, it contributes to the longevity of the material during charge/discharge cycles. Furthermore, imbedded PANI, as an ...
However, unraveling the relationship between the atomic surface structure and other physical and chemical properties of complex metal oxides is challenging due to the mixed ionic and covalent bonding that can occur in these minerals. Nonetheless, with the rapid increase in computer processing speed and...
[1]. Boron’s capacity to persist in three and four-oxygen-coordinated environments, coupled with the robust nature of covalent B–O bonds, facilitates the formation of stable borate glasses. It is now established that, in amorphous B2O3, the predominant structural units are BO3triangles that ...
it is proposed that the adsorption of the cyanide anion is not governed by interactions of electrostatic attraction but by the very possible formation of complexes by coordinated covalent bonds, followed by photooxidation from the surface of the oxides when the oxidizing species are generated when the...
