Regulating Oxygen‐Mediated Reconstruction during Cooling: A New Design Principle for High‐Capacity Sodium Manganese Oxide Cathodes

open access: yesAdvanced Science, EarlyView.
The cooling process during the solid‐state synthesis of sodium manganese oxides governs oxygen‐mediated reconstruction. Slow cooling promotes a stacking‐fault‐rich framework that suppresses Mn migration, mitigates O2 release, and stabilizes oxygen redox with reduced voltage hysteresis.

Engineering Na‐Rich P2‐Type Layered Oxides Through Li/Ti Dual Doping for Oxygen Redox Activation and Superior Structural Stability

open access: yesAdvanced Energy Materials, EarlyView.
P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Electrochemical and Thermal Interplay in Blended Cathodes for All Solid‐State Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work analyzes blended LFP‐NMC cathodes for all solid state batteries, revealing their balanced rate performance and enhanced thermal properties. Operando X‐ray diffraction studies uncovered lithiation gradients and asymmetric charging effects due to kinetic limitations.

Autonomous X‐Ray Fluorescence Mapping for Nanoscale Chemical Speciation of Fine Particulate Matter

open access: yesAdvanced Intelligent Discovery, EarlyView.
We present X‐AutoMap, an autonomous X‐ray fluorescence mapping framework that integrates real‐time analysis with rule‐based computer vision to selectively target chemically relevant regions. By avoiding background‐dominated areas, the method reduces acquisition time by fourfold while enabling accurate particle‐level speciation.

Monitoring Changes in Sperm Concentration and Quality Help Improve Captive Breeding Outcomes of the Endangered Amphibian Rawlinsonia littlejohni

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Amphibians are among the most threatened taxonomic groups, with many species experiencing rapid declines that have resulted in small, isolated populations vulnerable to inbreeding depression and reduced fertility. One major outcome of inbreeding is lowered fecundity, often linked to morphological changes in gametes.

Ultrasound findings associated with neonatal acute liver failure secondary to gestational alloimmune liver disease: A case series

open access: yesJPGN Reports, EarlyView.
Abstract Objectives Gestational alloimmune liver disease is the leading cause of neonatal acute liver failure, hypothesized to emerge from maternal exposure to an antigen that is expressed on fetal hepatocytes, resulting in maternal‐fetal alloimmune attack and activation of the complement cascade.

Oxidation‐Induced Internal Chemical Patterning in Copper–Gold Nanoalloys

open access: yesSmall, EarlyView.
Surface oxidation suppresses Au surface segregation and redirects Au transport to twin boundaries, replacing conventional core–shell formation with internal chemical patterning. Driven by Cu–Au mixing thermodynamics, defect‐mediated uphill diffusion creates alternating Au‐rich and Cu‐rich lamellae, revealing oxidation as a chemical pump for bulk ...

Social Dynamics in Zoo‐Housed Bush Dogs (Speothos venaticus) Following Group Changes

open access: yesZoo Biology, EarlyView.
We observed a pack of bush dogs over 10 months to measure changes in group structure following the birth of a pup and removal of an adult female. The pack displayed a robust social network and a single social hierarchy, with higher ranking members having more influence on collective movements.

Gender‐Sensitive Resilience in Kyrgyz Households: Latent Profile and Cross‐Lagged Dynamic Panel Approaches

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Resilience is still conceptualised as gender‐neutral in research and policy discussions. However, a gendered resilience framework suggests that gender roles and intra‐household dynamics are intricately linked with household resilience. This manuscript aims to analyse the effect of gender role attitudes on climate change resilience.

Vaccine Hunting: Balancing Strategic Independence, Cooperation and Multilateral Obligations in Scandinavian COVID‐19 Vaccine Diplomacy

open access: yesGlobal Policy, EarlyView.
ABSTRACT How do states navigate the balance between multilateral obligations, bilateral cooperation and strategic independence during global crises? This article provides an in‐depth empirical analysis of the diplomatic efforts deployed by Denmark and Norway to secure vaccine access during the COVID‐19 pandemic.
