In this study, hollow micron zero-valent iron (H-mZVI) was prepared using the ethylenediamine liquid phase reduction method. The microstructures were characterized by SEM, XRD, BET and FTIR. The results showed that H-mZVI possessed a spherical hollow structure with a particle size of approximately 1 μm.

Clothianidin (CTD), a highly water soluble neonicotinoid insecticide, easily enters water through runoff. Developing eco-friendly materials to degrade CTD is essential. Nano zero valent iron (nZVI) is effective for contaminant removal, but it deactivates due to agglomeration.

Ferrate is a promising oxidizing agent for water treatment. Understanding the reaction characteristics and transformation mechanism of high-valent intermediate irons [Fe(V) and Fe(IV)] remains challenging. Here, we systematically investigated the roles of Fe(VI), Fe(V), and Fe(IV) species for acetaminophen oxidation using reaction kinetics, products, and stoichiometries.

Multiple sclerosis (MS) is a chronic autoimmune disorder of the central nervous system characterized by demyelination, neuroinflammation, and neurodegeneration. Recent studies highlight the role of cerebral iron (Fe) accumulation in exacerbating MS pathophysiology. Fe, essential for neural function, contributes to oxidative stress and inflammation when dysregulated, particularly in the brain's gray matter and demyelinated lesions.

Atherosclerosis (AS) is a growing global health epidemic and is the leading cause of cardiovascular health problems, including ischemic stroke, coronary artery disease, and peripheral vascular disease. Despite extensive research on the underlying mechanisms of AS, iron remains an under-investigated mediator in the atherosclerotic process. Iron's involvement in AS is primarily linked to the iron-induced programmed cell death process known as ferroptosis.
