Chromatic symmetric functions via the group algebra of $S_n$

We prove some Schur positivity results for the chromatic symmetric function $X_G$ of a (hyper)graph $G$, using connections to the group algebra of the symmetric group.

Formation and Characterization of Insoluble Anthocyanins‐λ‐carrageenan Biopolyelectrolyte Complexes: Structural Morphology, Thermal Stability, and Release Dynamics

ChemFoodChem, Volume 2, Issue 2, June 2026.
Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.

Canal Construction Disrupts Camouflage in Two Sympatric Estuarine Crab Species

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Estuarine ecosystems provide essential habitats for fiddler crabs, whose survival heavily relies on background‐matching camouflage. Anthropogenic modifications such as canal construction can alter the visual properties of these habitats, yet direct empirical evidence of their impact on crustacean camouflage remains limited.

Toward Moisture Improvement of Eu2+‐Doped UCr4C4 Phosphor: A Facile Uniform Coating Strategy and Mechanism

Information &Functional Materials, Volume 3, Issue 2, Page 59-65, June 2026.
This study develops a facile multi‐step coating protocol to enhance the humidity stability of the Eu2+‐doped UCr4C4 green phosphor RbLi(Li3SiO4)2: Eu2+ (RLSO: Eu2+), successfully overcoming the typical trade‐off between luminescence intensity and stability.
