Unlocking Energy Potential: Exploiting Anionic Redox Activity in Na‐Based Layered Oxides

open access: yesSmall, EarlyView.
Anionic redox in Na‐based layered oxide cathodes unlocks additional capacity beyond conventional transition‐metal redox limits, enabling high‐energy sodium‐ion batteries. This review elucidates coupled cationicanionic redox mechanisms across P2‐, O3‐, and related structural phases, while critically addressing key challenges such as voltage hysteresis ...

Positive Aging‐Free Quantum Dot Light‐Emitting Diodes Enabled by Single‐Source Chloride‐Doped ZnMgO Electron Transport Layers

open access: yesSmall, EarlyView.
Single‐source chloride doping of ZnMgO electron‐transport layers (ETLs) intrinsically suppresses oxygen‐vacancy traps, eliminating storage‐driven positive aging in quantum dot light‐emitting diodes. Devices deliver day‐0 peak external quantum efficiency and longer operational lifetimes, while transport and interfacial photoluminescence remain time ...

Interannual Variations of TOA Albedo over the Arctic, Antarctic and Tibetan Plateau in 2000–2019

open access: yesRemote Sensing, 2020
Recent changes in Earth’s climate system have significantly affected the radiation budget and its year-to-year variations at top of the atmosphere (TOA). Observing high-latitude TOA fluxes is still challenging from space, because spatial inhomogeneity of

Extending reliability to intensive longitudinal data with the Kalman filter

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Reliability is central to how researchers approach measurement in standard, group‐based analyses of single‐time‐point data, yet this critical aspect is often overlooked in the analysis of repeated observations. Since its inception, reliability has been a between‐person concept, but we redevelop this notion for within‐person designs by ...
