Unraveling the Thermal Response From Individual Multipole Resonances in Magnetodielectric Spheres

open access: yesAdvanced Photonics Research, Volume 7, Issue 9, September 2026.
A semi‐analytical framework resolves electromagnetic heating into individual multipolar contributions and an inter‐order coupling correction, linking internal modal fields to local dissipation, temperature evolution, and heat flux. Applied to dual‐symmetric magnetodielectric spheres, it reveals balanced polarization and magnetization losses and ...

How to Make a Phosphine by Catalytic Hydrophosphination

open access: yesChemistry–Methods, Volume 6, Issue 9, September 2026.
Catalysis is the winning hand for hydrophosphination. Three general advances, electrophilic metals, ionic and solvent effects, and photocatalysis have allowed for large categories of unsaturated and phosphine substrates to be accessed. Through these advances, a catalyst that can provide good conversion for most substrates can now be found. Implications

Fractional Balanced Chromatic Number and Arboricity of Planar (Signed) Graphs

open access: yesJournal of Graph Theory, Volume 113, Issue 1, Page 5-18, September 2026.
ABSTRACT A balanced ( p , q )‐coloring of a signed graph ( G , σ ) is an assignment of q colors to each vertex of G from a platter of p colors, such that each color class induces a balanced set (a set that does not induce a negative cycle). The fractional balanced chromatic number of ( G , σ ), denoted χ f b ( G , σ ), is the minimum ratio p / q such ...

Orientations of Graphs With at Most One Directed Path Between Every Pair of Vertices

open access: yesJournal of Graph Theory, Volume 113, Issue 1, Page 143-164, September 2026.
ABSTRACT Given a graph G, we say that an orientation D of G is a KT orientation if, for all u , v ∈ V ( D ), there is at most one directed path (in any direction) between u and v. Graphs that admit such orientations have been used to construct graphs with large chromatic number and small clique number that served as counterexamples to various ...
