Analysis of the Fe 2p XPS for hematite 𝛂 Fe2O3: Consequences of covalent bonding and orbital splittings on multiplet splittings (open access)

Analysis of the Fe 2p XPS for hematite 𝛂 Fe2O3: Consequences of covalent bonding and orbital splittings on multiplet splittings

Article analyzes the origins of the complex Fe 2p X-Ray Photoelectron Spectra (XPS) of hematite (α-Fe₂O₃) and is related to the character of the bonding in this compound. This analysis provides a new and novel view of the reasons for XPS binding energies (BEs) and BE shifts, which deepens the current understanding and interpretation of the physical and chemical significance of the XPS. This article is part of the JCP Special Topic on Oxide Chemistry and Catalysis.

Multifeature analyses of vascular cambial cells reveal longevity mechanisms in old Ginkgo biloba trees (open access)

Multifeature analyses of vascular cambial cells reveal longevity mechanisms in old Ginkgo biloba trees

This article investigates age-related changes in Ginkgo biloba trees to learn more about the molecular and metabolic mechanisms underlying their longevity. The results revealed that long-lived trees have evolved compensatory mechanisms to maintain a balance between growth and aging processes.
