Ultrathin Aluminum–Air Batteries via Hygroscopic Electrolytes for Continuous Operation of Imperceptible On‐Skin Electronics

Advanced Energy Materials, EarlyView.
This study presents ultrathin, high‐capacity aluminum‐air batteries (AABs) for self‐sustaining, skin‐conformal electronics. By utilizing ambient moisture and oxygen alongside a LiCl‐based hygroscopic hydrogel electrolyte, the design significantly reduces battery thickness while preventing dehydration and Al self‐corrosion.

Beyond the Gold Standard: Towards Industrially Viable Electrodes for Durable Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Transparent and opaque electrode materials are mapped by raw material cost per 1 m2 electrode area and retained median device efficiency after heat–light ageing. FTO offers a lower‐cost and more stable alternative to ITO, while Cr/Al provides the lowest‐cost rear electrode investigated with Au‐like stability and substantially improved durability ...

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology

Advanced Intelligent Discovery, EarlyView.
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures

Heat Transfer Fluids as Co‐Diluents in Localized High‐Concentration Electrolytes for High‐Rate Lithium Metal Batteries With Enhanced Safety

Angewandte Chemie International Edition, EarlyView.
Two fluorinated ethers, commonly used as heat‐transfer fluids, are explored as co‐diluents in localized high‐concentration electrolytes (LHCEs) for lithium metal‐based batteries. The best‐performing ternary diluent blend boosts ion mobility and cuts overvoltages, thereby improving Coulombic efficiency and cycle life at ≥1 mA cm−2 in zero‐excess pouch ...

Bottlebrush Polyolefin Sulfones as Triggerable and Degradable Pressure‐Sensitive Adhesives

Angewandte Chemie International Edition, EarlyView.
A grafting‐through alternating copolymerization strategy yields poly(norbornene sulfone) bottlebrush polymers with high molar mass. These materials function as additive‐free pressure‐sensitive adhesives. The incorporation of cleavable sulfone units enables rapid breakdown under mild alkaline conditions, providing a pathway toward sustainable, high ...
