The dⁿ Number in Transition Metal Chemistry: Its Utility and Limitations

Chemistry, 2023
The dn number or configuration is a very useful parameter in transition metal chemistry because it conveys information about the expected properties of a d-block metal complex, including its shape, magnetism, thermodynamic stability, kinetic lability ...

Oxidation of cellulose in pressurized carbon dioxide [PDF]

, 2009
This work presents first results upon oxidation of type II cellulose by nitrogen dioxide dissolved in carbon dioxide at high pressure. This reaction leads to oxidized cellulose, a natural-based bioresorbable fabric used for biomedical applications.

Chemical Bonding Analysis on Amphoteric Hydrogen - Alkaline Earth Ammine Borohydrides

, 2017
Usually the ions in solid are in the positive oxidation states or in the negative oxidation state depending upon the chemical environment. It is highly unusual for an ion having both positive as well as negative oxidation state in a particular compound ...

Oxidation States: Intrinsically Ambiguous?

ACS Central Science
The oxidation state ( OS ) formalism is a much-appreciated good in chemistry, receiving wide application. However, like all formalisms, limitations are inescapable, some of which have been recently explored. Providing a broader context, we discuss the OS and its interpretation from a computational perspective for transition metal (TM) complexes.
