Exploring Aromaticity in Expanded Porphyrins: A Multidimensional Approach to Structure–Property Relationships

open access: yesChemistry–Methods, Volume 5, Issue 12, November 2025.
Expanded porphyrins, with their flexible structures and rich redox chemistry, offer a powerful platform to explore how aromaticity shapes molecular properties. This review introduces a multidimensional framework to quantify Hückel and Möbius aromaticity and examines its impact on the spectroscopic behavior across redox‐ and topology‐controlled expanded

Local Conditions and Environmental Gradients Shape the Abundance and Size Structure of a Non‐Native Intertidal Species in Atlantic North America

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We investigated how density and body size of the non‐native intertidal snail Littorina littorea vary along a 10° latitudinal gradient (> 1700 km) in North America. Our analyses show that local substrate complexity drives density patterns, whereas body size is shaped by climatic factors, with higher and more variable summer temperatures reducing ...

A Two‐Stage Robust Optimization Method for Grid‐Connected Energy Storage to Improve the Resilience of Distribution Networks

open access: yesEngineering Reports, Volume 7, Issue 12, December 2025.
A two‐stage robust optimization model is developed, where the planning layer determines the optimal siting and sizing of grid‐connected energy storage systems by minimizing investment and operational costs. The operating layer optimizes GES scheduling under disturbance scenarios to minimize load loss, effectively enhancing distribution network ...
