Prediction of Cyclic O6 Molecules Stabilized by Helium under Pressure
Advanced Science, Volume 12, Issue 11, March 20, 2025.The cyclic O6 molecules may exist due to the presence of analogical S6 and Se6. However, such O6 rings are never achieved due to unfavorable energy. Strikingly, a stable compound of HeO3 is discovered under pressure, consisting of neutral He atoms and O6 molecules.

Convex hull realizations of the multiplihedra [PDF]
Topology and its Applications, 2008 We present a simple algorithm for determining the extremal points in Euclidean space whose convex hull is the nth polytope in the sequence known as the multiplihedra. This answers the open question of whether the multiplihedra could be realized as convex polytopes. We use this realization to unite the approach to A_n-maps of Iwase and Mimura to that of

Realizing Intrinsically Ultralow and Glass‐Like Thermal Transport via Chemical Bonding Engineering
Advanced Science, Volume 12, Issue 17, May 8, 2025.Lattice thermal conductivity can be effectively suppressed by introducing a S2 − anion into the bridging position between the Ag–Ag bond in the Ag6 octahedron, which weakens the Ag–Ag bond within the octahedral structure and enhances phonon‐phonon scattering rates. Abstract Crystals exhibiting glass‐like and low lattice thermal conductivity (κL$\kappa_{

Two-Term Disjunctions on the Second-Order Cone
, 2014 Balas introduced disjunctive cuts in the 1970s for mixed-integer linear programs. Several recent papers have attempted to extend this work to mixed-integer conic programs.

Advanced Science, EarlyView.A synergistic framework for interpretable ML‐assisted target discovery of selenoborates is developed. ABa3(BSe3)2X (A = Rb, Cs; X = Cl, Br, I) are successfully predicted and synthesized, exhibiting significant potential to be promising IR functional materials. This work promotes the cooperation of ML technology and materials science.

Strain Fluctuations Unlock Ferroelectricity in Wurtzites
Advanced Electronic Materials, Volume 11, Issue 5, April 2025.In this study, Steven M. Baksa and his colleagues unveiled the atomistic mechanisms of ferroelectric reversal in Mg‐substituted ZnO where Mg cations induce strain fluctuations, triggering ferroelectricity via sequential reversal. They also demonstrate that Zn:Mg composition gradients along the polar axis promotes polarization reversal, providing new ...
