Main genetic entities associated with tooth agenesis.

Background: Tooth agenesis refers to the absence of one or more of the deciduous or permanent teeth. Tooth agenesis results from a series of disrupted reciprocal ectodermal mesenchymal interactions taking place during the early stages of tooth development.

Methods: A narrative literature review was performed to describe the main genetic syndromes associated with tooth agenesis.

Engineering Magnetic Heterostructures with Synergistic Regulation of Charge-Transfer and Spin-Ordering for Enhanced Water Oxidation.

The design of heterojunctions offers a crucial solution for energy conversion and storage challenges, but current research predominantly focuses on charge transfer benefits, often neglecting spin attribute regulation despite the increasing recognition of spin-sensitivity in many chemical reactions. In this study, a novel magnetic heterostructure, CoFeO@CoFeMoO, is designed to simultaneously modulate charge and spin characteristics, and systematically elucidated their synergistic impact on the oxygen evolution reaction (OER). Experimental results and density functional theory calculations confirmed that the magnetic heterostructure exhibits both charge transfer and spin polarization.

Creating Spin Channels in SrCoO through Trigonal-to-Cubic Structural Transformation for Enhanced Oxygen Evolution/Reduction Reactions.

Oxygen evolution and reduction reactions (OER and ORR) play crucial roles in energy conversion processes such as water splitting and air batteries, where spin dynamics inherently influence their efficiency. However, the specific contribution of spin has yet to be fully understood. In this study, we intentionally introduce a spin channel through the transformation of trigonal antiferromagnetic SrCoO into cubic ferromagnetic SrCoO, aiming to deepen our understanding of spin dynamics in catalytic reactions.

Reactivity of Ultrathin Kagome Metal FeSn toward Oxygen and Water.

The kagome metal FeSn consists of alternating layers of kagome-lattice FeSn and honeycomb Sn and exhibits great potential for applications in future low-energy electronics and spintronics because of an ideal combination of topological phases and high-temperature magnetic ordering. Robust synthesis methods for ultrathin FeSn films, as well as an understanding of their air stability, are crucial for its development and long-term operation in future devices. In this work, we realize large-area, <10 nm thick, epitaxial FeSn thin films and explore the oxidation process synchrotron-based photoelectron spectroscopy using oxygen and water dosing, as well as air exposure.
