On the origin of univalent Mg+^+ ions in solution and their role in anomalous anodic hydrogen evolution

This study utilizes advanced \emph{ab initio} simulations to reveal that the anomalous anodic hydrogen evolution and violent dissolution of magnesium are caused by the formation of a solvated [Mg2+^{2+}(OH)^-]+^+ complex, which explains the previously elusive presence of univalent Mg+^+ ions and the failure of protective oxide layers.

Stability of Highly Hydrogenated Monolayer Graphene in Ultra-High Vacuum and in Air

This study demonstrates that highly hydrogenated monolayer graphene exhibits long-term stability in ultra-high vacuum but rapidly oxidizes in air, a process that can be effectively reversed through re-exposure to atomic hydrogen, highlighting its potential for hydrogen storage applications.

Accessing quasi-flat f\textit{f}-bands to harvest large Berry curvature in NdGaSi

This study demonstrates that the ferromagnetic ground state of single-crystalline NdGaSi splits quasi-flat 4f bands near the Fermi energy, enabling localized f-electrons to directly generate a record-breaking intrinsic anomalous Hall conductivity of 1165 Ω1\Omega^{-1} cm1^{-1}, a phenomenon absent in its non-magnetic analog NdAlSi.

Electrically driven plasmon-polaritonic bistability in Dirac electron tunneling transistors

This paper reports the first experimental demonstration of electrically driven plasmon-polaritonic bistability in graphene/hexagonal-boron-nitride/graphene tunneling transistors, achieved through momentum-conserving resonant tunneling of Dirac electrons and tunable via load resistance and electrostatic gating.
