Ionic and covalent mixed-metal complexes by reaction of transition metal M H acids (M=Mo, Mn, Fe, Co) with [Ir(PMe 3 ) 4 CH 3 ] or [Rh(PMe 3 ) 3 CH 3 ] and structurally related Rh M and Ir M heterobimetallics (M=Mn, Fe, Ru)...
Molten salt systems with ionized cations and anions endow a strong polarizing force, which is capable of breaking metallic, covalent or ionic bonds. Therefore, molten salt strategy has been exploited to obtain various nanomaterials, including precious metal, metal oxide and carbon materials with ...
Answer to: Give the name of Fe2O3 and classify it as an ionic or covalent compound. By signing up, you'll get thousands of step-by-step solutions...
For example, the linkage can be chemical or enzymatic, and can be covalent, ionic, or hydrophobic in nature. For many applications, especially biological and biomedical applications, it is important to produce Fe/Au nanoparticles that are water-soluble. That is, they must be functionalized so ...
(SACs)3,4,5, wherein the metal atoms are located individually on support and are stabilized by neighboring surface atoms through covalent coordination or ionic interactions, and the coordination atoms could drastically tune the electronic and geometric structure of the supported single metal atoms6,7...

Thus, it is necessary to study the effect of ionic strength on iAs adsorption. No significant change of the adsorption efficiency was observed in the pres- ence of NaCl with concentrations up to 0.2 M in pH 4–10 (Fig. 3C and D), suggesting that the iAs adsorption on Scientific ...
