Probing FeSi, a d-electron topological Kondo insulator candidate, with magnetic field, pressure, and microwaves [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2022 Significance The properties of the correlated electron small gap semiconductor FeSi are reminiscent of those of a small class of lanthanide- and actinide-based compounds known as Kondo insulators.

Oral Hygiene Status, Tooth Loss, and Periodontal Disease Severity in Mexican Adults: A Cross-Sectional Study. [PDF]
Int J DentObjective Periodontal disease is a chronic condition, and its etiology is mainly related to biofilm and the destruction of the attachment apparatus resulting from poor application of oral hygiene measures. The aim was to study the relationship between oral hygiene and the severity of periodontal disease, in addition to evaluating the relationship ...

The Fe-FeSi phase diagram at Mercury’s core conditions
Nature Communications, 2022 Mercury’s metallic core is expected to have formed under highly reducing conditions, resulting in the presence of significant quantities of silicon alloyed to iron. Here we present the phase diagram of the Fe-FeSi system, reconstructed from in situ X-ray
