Modeling of magnetic properties of A2BB′O6 compounds using ab initio and Monte Carlo methods

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 12, December 2025.
Ab initio and Monte Carlo simulations were employed to maximize the estimated Curie temperature of A2BB′O6 oxides. It was revealed that the element A ion radius should be as small as possible, while the magnetic moments of B and B′ elements should be as large as possible.

Dual‐Confinement Strategy Improves the Stability of High‐Entropy Alloys in Ultra‐Large Current Zinc‐Air Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 6, November 2025.
Illustration of the synthetic route and mechanism of HEAs with dual‐confinement strategy. This study developed a symbiotic dual‐confinement strategy integrating interstitial oxygen doping and carbon coating to enhance high‐entropy alloys for high‐current‐density zinc‐air batteries.

Spanning Plane Subgraphs of 1‐Plane Graphs

open access: yesJournal of Graph Theory, Volume 110, Issue 3, Page 290-297, November 2025.
ABSTRACT A graph drawn on the plane is called 1‐plane if each edge is crossed at most once by another edge. In this paper, we show that every 4‐edge‐connected 1‐plane graph has a connected spanning plane subgraph. We also show that there exist infinitely many 4‐connected 1‐plane graphs that have no 2‐connected spanning plane subgraphs.

Recognizing Trees From Incomplete Decks

open access: yesJournal of Graph Theory, Volume 110, Issue 3, Page 322-336, November 2025.
ABSTRACT Given a graph G, the unlabeled subgraphs G − v are called the cards of G. The deck of G is the multiset { G − v : v ∈ V ( G ) }. Wendy Myrvold showed that a disconnected graph and a connected graph both on n vertices have at most ⌊ n 2 ⌋ + 1 cards in common and found (infinite) families of trees and disconnected forests for which this upper ...
