Forbidden Pairs with a Common Graph Generating Almost the Same Sets
The Electronic Journal of Combinatorics, 2017 Let $\mathcal{H}$ be a family of connected graphs. A graph $G$ is said to be $\mathcal{H}$-free if $G$ does not contain any members of $\mathcal{H}$ as an induced subgraph. Let $\mathcal{F}(\mathcal{H})$ be the family of connected $\mathcal{H}$-free graphs.

Chiral Altermagnetic Magnetoelectrics
Advanced Materials, EarlyView.In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler
Advanced Materials, EarlyView.An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

Isospin Symmetry Violation in sd-Shell Nuclei
EPJ Web of Conferences, 2014 We construct a new set of isospin-nonconserving (INC) shell-model Hamiltonians and apply it (i) to study the isobaric-mass multiplet equation (IMME) beyond a quadratic form in the A = 35, 3/2+ quartet, (ii) to compute the isospin mixing corrections to ...

Choosability of graphs with infinite sets of forbidden differences
Discrete Mathematics, 2007 Suppose \(G\) is a (finite) graph, \(T\) is a set of non-negative integers, and for each vertex \(v\) of \(G\) we are given a set \(L(v)\) of integers. \(G\) is \(T\)-colorable from the list-assigment \(L\) if it is possible to choose for each vertex a color \(c(v)\in L(v)\) in such a way that \(\left| c(v)-c(w)\right| \not\in T\) whenever \(v\) and ...

Barrier‐Assisted Plasma Doping for Spatially Selective Resistance Engineering in MoS2 Transistors
Advanced Materials, EarlyView.Barrier‐assisted NH3 plasma doping enables damage‐free, spatially selective carrier modulation in monolayer MoS2 transistors. An ultrathin pV3D3/Al2O3 protective‐dielectric stack acts as a chemical filter that allows NHx radicals to reach the MoS2 surface while blocking plasma damage. This process achieves a high electron concentration of 4.3 × 1013 cm−

Lead‐Free Chiral Hybrid Metal Halides for Circularly Polarized Light‐Emitting Diodes
Advanced Optical Materials, EarlyView.Lead‐free chiral hybrid metal halides provide a versatile platform for realizing chiroptical responses through chiral modulation of metal–halide frameworks with diverse dimensionalities, induces inversion‐symmetry breaking and enables dissymmetric excited‐state transitions toward efficient circularly polarized luminescence and electroluminescence.
