Acid/Base‐Responsive Circularly Polarized Luminescence Emitters with Configurationally Stable Nitrogen Stereogenic Centers

open access: yesAdvanced Materials, EarlyView.
Circularly Polarized Luminescence (CPL) emitters based on Tröger's base analogues bearing two peripheral fluorophores (anthracene, pyrene or 9,9‐dimethylfluorene) are prepared following a straightforward and versatile synthetic approach from common precursors.

Quantum conformal symmetries for spacetimes in superposition

open access: yesQuantum
Without a complete theory of quantum gravity, the question of how quantum fields and quantum particles behave in a superposition of spacetimes seems beyond the reach of theoretical and experimental investigations. Here we use an extension of the quantum reference frame formalism to address this question for the Klein-Gordon field residing on a ...

Decoding Chemo‐Mechanical Failure Mechanisms of Solid‐State Lithium Metal Battery Under Low Stack Pressure via Optical Fiber Sensors

open access: yesAdvanced Materials, EarlyView.
By FBG sensing the Li/electrolyte interfacial stress in solid‐state battery, the Li metal anode failure reasons as dendrite‐induced uneven stress distribution at electrode/electrolyte interface are disclosed. A Li–Sn composite anode is demonstrated effective in stabilizing the interface mechanics and the solid‐state full cell performance at low stack ...

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG
