From Cages to Sheets: Computational Elucidation of Methylaluminoxane Structure and Reactivity

open access: yesChemPlusChem, Volume 91, Issue 8, August 2026.
Methylaluminoxane (MAO), the dominant cocatalyst in metallocene‐based olefin polymerization, has resisted structural characterization for decades. This review traces the computational journey from early cage and nanotube proposals to the identification of two‐dimensional aluminoxane sheets as the thermodynamically preferred motif, and how this ...

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

open access: yesAdvanced Functional Materials, Volume 36, Issue 58, 20 July 2026.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

open access: yesAdvanced Science, Volume 13, Issue 37, 3 July 2026.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Prioritizing bat roosts for conservation with a global multicriteria bat roost priority index based on community science

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.
