Iron, as a topic, encompasses its roles and behavior across diverse scientific domains, including its coordination chemistry, redox properties, and biological functions. Central to many metalloproteins, iron cycles between Fe²⁺ and Fe³⁺ states, enabling electron transfer, oxygen transport, and catalysis in systems such as hemoglobin, cytochromes, and iron–sulfur clusters. In materials science, iron’s allotropic transformations, magnetic ordering, and alloy formation underlie the properties of steels and other ferrous materials. In geoscience, iron participates in redox-sensitive mineral formation and biogeochemical cycling, influencing atmospheric composition, nutrient availability, and environmental redox gradients across terrestrial and marine systems.
Iron (Fe) is an essential micronutrient for the healthy growth of plants, including many staple crops like rice. Its deficiency remains a common agricultural problem that slashes crop yields, as it leads to impaired photosynthesis, ...
