Anatomy of a SPAN Particle: A Four‐Level Structural Framework for Lithium–Sulfur Batteries
Sulfurized polyacrylonitrile (SPAN) is a key cathode material for batteries. Borrowing the four‐level classification of protein structure, this perspective demonstrates SPAN's structural complexity into well‐defined levels, giving researchers clear research boundaries and targets at each level for improving battery performance.

Resilience in a noisy urban system
Abstract The ability of cities to recuperate from disturbances and return to their evolutionary pathways depends, first and foremost, on the type of damage that the shock created. But in addition, it depends on how information is transmitted in the urban system and on how noise filters distort the information that reaches economic agents.

The Feasibility Test of Electric Propulsion Systems: Case Study for a Light and Fixed‐Wing Aircraft
ABSTRACT This study investigates the feasibility and performance of a fully electric propulsion system (EPS) integrated into a light fixed‐wing aircraft. The system consists of a 65 kW‐class electric motor, a high‐efficiency inverter, and dual lithium‐ion battery packs with a total capacity of 27 kWh—collectively engineered to fulfill both power ...

Caribou forage lichens were present in post‐burn lodgepole pine stands multiple decades before stem‐density was likely open enough to attract wintering caribou. We posit that the prolonged self‐thinning of lodgepole pine after fire may be a greater limiting factor than lichen abundance for habitat recovery in lodgepole pine forests.
