A Dual‐Modal Wearable Pulse Detection System Integrated with Deep Learning for High‐Accuracy and Low‐Power Sleep Apnea Monitoring

open access: yesAdvanced Science, EarlyView.
A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.

The SlDOF9‐SlSWEET17 Module: a Switch for Controlling Sugar Distribution Between Nematode Induced Galls and Roots in Tomato

open access: yesAdvanced Science, EarlyView.
Root‐knot nematode (RKN) disease seriously affects the yield and quality of vegetable crops. SlDOF9‐SlSWEET17 model helps plants resist RKN infection during early stage by switching off the sugar transport capacity of other SlSWEET proteins that are hijacked by RKNs.

Transition Metal Slab Gliding: One Key Process for Activating Anionic Redox Reaction in P2‐Type Transition Metal Oxide Cathodes

open access: yesAdvanced Science, EarlyView.
Transition metal (TM) slab gliding is a key process for activating anionic redox reaction in P‐type layered oxide materials. Disordered TM layer weakens interlayer interactions and facilitates TM slab gliding. The resulting O‐type layer promotes reversible TM migration, provides the necessary Na–O–□TM configuration, and activates anionic redox reaction.

Recycling Defunct Lithium‐Ion Battery Cathodes to Quaternary Layered Double Hydroxides for Efficient Oxygen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
Li(Co0.8Ni0.1Mn0.1)O2 and LiFePO4 cathode materials are functional recycled by simple leaching and co‐precipitation methods to synthesize Quaternary iron‐nickel‐cobalt‐manganese hydrotalcites as oxygen‐evolution‐reaction catalysts. The highly disordered structure and strong electronic interactions between metal cations result in excellent catalytic ...
