On Zero-Divisor Graphs of Z_n When n Is Square-Free

Axioms
In this article, some properties of the zero-divisor graph Γ(Zn) are investigated when n is a square-free positive integer. It is shown that the zero-divisor graph Γ(Zn) of ring Zn is a (2k−2)-partite graph when the prime decomposition of n contains k ...

Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet

Advanced Materials, EarlyView.
Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

On Sheffer Stroke Be-Algebras

Discussiones Mathematicae - General Algebra and Applications, 2022
In this paper we introduce Sheffer stroke BE-algebras (briefly, SBE-algebras) and investigate a relationship between SBE-algebras and BE-algebras. By presenting a SBE-filter, an upper set and a SBE-subalgebra on a SBE-algebra, it is shown that any SBE ...

Open Filters and Congruence Relations on Self-Distributive Weak Heyting Algebras

Bulletin of the Section of Logic
In this paper, we study (open) filters and deductive systems of self-distributive weak Heyting algebras (SDWH-algebras) and obtain some results which determine the relationship between them. We show that the variety of SDWH-algebras is not weakly regular

Interphase Self‐Optimization Enables Stable Magnesium Anode in Hydrogel Electrolyte

Advanced Materials, EarlyView.
Based on a MgCl2 hydrogel electrolyte, we identify a tridentate chelant additive to construct a magnesium oxychloride interphase on Mg metal anodes. This self‐optimized interphase enables low‐resistance Mg2+ stripping/plating, resulting in much elongated cycling life of 600 h with 0.24 V nucleation overpotential.
