Water‐Efficient Smart Drip Irrigation Enabled by a Low‐Power and High‐Efficiency Flexible Electromagnetic Actuator

open access: yesAdvanced Science, EarlyView.
Water scarcity poses a critical threat to global food security. A low‐power, flexible electromagnetic actuator is presented for smart drip irrigation systems. The device achieves precise, wide‐range flow modulation (0.05–5.8 mL/min) in response to real‐time plant demands, reducing water consumption compared to conventional flood irrigation.

pH/ROS‐Responsive Injectable Hydrogel Co‐Loaded with B7‐H3 Blocker and NETs Suppressor Boosts OSCC Synergistic Immunotherapy

open access: yesAdvanced Science, EarlyView.
A pH/ROS‐dual‐responsive injectable hydrogel, formed by dynamic boronic ester and Schiff base crosslinking, co‐delivers enoblituzumab (B7‐H3 blocker) and Cl‐amidine (NETs suppressor). Via localized intratumoral delivery, it synergistically reprograms the immunosuppressive tumor microenvironment, overcomes T cell infiltration barriers, restores ...

Wide‐Range Adaptive Metal Oxide for Hydrogen Sulfide Detection From Earth to Space‐Like Environments

open access: yesAdvanced Science, EarlyView.
This work presents a gas sensing platform based on Cu‐doped SnO2 microspheres that operates reliably from ambient to space‐like conditions. The sensor maintains performance across vacuum and cryogenic environments, bypassing traditional oxygen‐mediated mechanisms, utilizing direct chemisorption and interfacial charge transfer.

Tunable Switching Mechanisms in HfZrO2‐Based Tunnel Junctions for High‐Performance Synaptic Arrays

open access: yesAdvanced Science, EarlyView.
This work demonstrates hybrid switching in engineered HZO‐based FTJs, enabled by controlled interlayer design and oxygen scavenging dynamics. The combined switching mechanism produces robust multilevel conductance states in large crossbar arrays, offering a materials‐driven pathway toward scalable in‐memory computing with enhanced tunability and ...
