Dimensionality‐Driven Emerging Phenomena in Hybrid Metal Halides

open access: yesSmall Structures, Volume 7, Issue 6, June 2026.
Emergent Phenomena Governed by Octahedral Connectivity and Dimensionality. Hybrid metal halides are unique among semiconductors in that their inorganic octahedral networks can be rationally assembled in 3D, 2D, 1D, and 0D forms, enabling dimensionality to assist as a powerful control knob over structure, electronic properties, excitations, and ...

l‐threo‐d‐galacto‐Octitol: a curious non‐classical order–disorder polytype with an 88 Å axis

open access: yesActa Crystallographica Section B, Volume 82, Issue 3, Page 352-359, June 2026.
The sugar alcohol l‐threo‐d‐galacto‐octitol crystallizes in a structure with P43212 pseudo‐symmetry and a highly elongated unit cell (c ≈ 88 Å). In distinct layers of the structure, symmetry is broken by an asymmetric hydrogen‐bonding network leading to polytypism, which is discussed in the framework of order–disorder theory.GalC8 [l‐threo‐d‐galacto ...

Occurrence of a Cavity‐Nesting Tropical Swallow Is Associated to Riverbed Lithology

open access: yesAustral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Understanding the factors shaping species distribution is a key challenge in ecology and biogeography. While dispersal limitations, environmental features, and biotic interactions are commonly recognized as key determinants of species abundance and distribution, some species exhibit patchy distributions that remain hard to explain.
