Understanding Stellar Mass–Metallicity and Size Relations in Simulated Ultrafaint Dwarf Galaxies
The Astrophysical JournalReproducing the physical characteristics of ultrafaint dwarf galaxies (UFDs) in cosmological simulations is challenging, particularly with respect to stellar metallicity and galaxy size.

, 2013 This chapter deals with the electronic structure of metal-metal bonds in molecular systems, a diverse topic that now spans almost the entire periodic table. The field is most often associated with strong multiple bonds such as the iconic quadruple bond in [Re2Cl8]2-, and the recently discovered ultra-short Cr-Cr quintuple bonds provide a remarkable ...

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics
Advanced Engineering Materials, EarlyView.Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

Potential-driven Metal Cycling: JADES Census of Gas-phase Metallicity for Galaxies at 1 < z < 7
The Astrophysical Journal LettersThe gravitational potential is established as a critical determinant of gas-phase metallicity (12+log(O/H)) in low-redshift galaxies, whereas its influence remains unconfirmed at high redshifts.

The Ultradiffuse Galaxy AGC 242019 with a Negative Metallicity Gradient
The Astrophysical JournalThe origin of ultradiffuse galaxies (UDGs) remains poorly understood. While the metallicity gradient can offer key clues about the formation mechanisms of UDGs, no such studies have been conducted for field UDGs.

New Solar Metallicity Measurements
Atoms, 2019 In the past years, a systematic downward revision of the metallicity of the Sun has led to the “solar modeling problem„, namely the disagreement between predictions of standard solar models and inferences from helioseismology.
