Degradable and Recyclable 3D‐Printed Pheromones Delivery System Reinforced by Metal Coordination Cross‐Linking for Efficient Pest Trapping

open access: yesAdvanced Science, EarlyView.
This study presents a 3D‐printed carrier for the slow release of insect pheromones. Reinforced by lignosulfonate and Fe³⁺ coordination in a cellulose acetate matrix, it enables sustained release for up to six weeks with remarkable trapping efficacy. Featuring soil degradability and recyclable re‐printing capability, this carrier provides a sustainable ...

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.
