Reaction‐Induced Reversible Reconstruction Enhanced Ni‐MgO/CaO Dual Functional Material for Stable CO2 Capture and In Situ Conversion

open access: yesAdvanced Science, EarlyView.
A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Young children's perspectives of time: New directions for co‐constructing understandings of quality in ECEC

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Children's relationship with time in preschools is an under‐researched area. Young children rarely know how to measure time using a clock, but their experiences of time may contribute to understanding children's well‐being and debates about quality in preschools.

Palatable‐Food–Driven Top‐Down Circuit Inhibits PVNCRF Activity to Mitigate Stress Via Peri‐PVNCRFR1 Neurons

open access: yesAdvanced Science, EarlyView.
Palatable food alleviates stress and prevents anxiety. This study uncovers a dedicated neural pathway: dopamine release in the PFC activates D1R neurons, whose projections to the peri‐PVN engage a population of anxiolytic CRFR1 neurons. These neurons then inhibit stress‐induced hyperactivity of PVNCRF neurons, providing a circuit‐level explanation for ...

Electrohydraulic Folding Ring Actuators for Radial Contraction

open access: yesAdvanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...
