Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives

open access: yesAdvanced Functional Materials, EarlyView.
A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management

open access: yesAdvanced Functional Materials, EarlyView.
A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...

Moderate Drought Constrains Crop Growth Without Altering Soil Organic Carbon Dynamics in Perennial Cup‐Plant and Silage Maize

open access: yesGCB Bioenergy
Silage maize (Zea mays L.) intensification to maximise biomass production increases greenhouse gas emissions, accelerates climate change and intensifies the search for alternative bioenergy crops with high carbon (C) sequestration capacity. The perennial

Attraction of Color Cups and Plant Compounds to Thrips Species on Organic Napa Cabbage

open access: yesJournal of Entomology, 2007
The thrips species, Thrips tabaci Lindeman and Frankliniella occidentalis (Pengande) (Thysanoptera: Thripidae), are the most common pests on agricultural crops in Colorado. The yellow cup baited with crushed freeze-dried canola pod extract caught significantly higher numbers of thrips species than baited with ground mustard seed in the first trial. The

Self‐Powered Permeable Electronic Dressing for Exudate Management, Electrostimulation and Drug Delivery in Chronic Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a self‐powered permeable electronic dressing (SPED) that synergistically integrates exudate management, electrical stimulation, and on‐demand drug delivery. The dressing effectively absorbs exudate while demonstrating potent antibacterial activity and accelerated tissue regeneration in diabetic mouse models, thereby promoting ...
