Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Non-surgical pneumoperitoneum and pneumoretroperitoneum associated with mechanical ventilation

, 2022
We present two rare cases of mechanical ventilation-associated barotrauma presenting with pneumoperitoneum and pneumoretroperitoneum separately. Pneumoperitoneum and pneumoretroperitoneum are not always associated with a hollow viscous perforation and ...

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Assessing ventilation rate measurements in a mechanically ventilated laying hen facility

Poultry Science, 2019
Gaseous emission in laying hen facilities affects animal production performance and the environment. Emission is ruled by gas concentration and ventilation rate (VR), which are the key parameters to estimate precise emission factors. In this work, VR were assessed in a mechanical ventilated laying hen facility under Mediterranean climate conditions ...

Improving Air Distribution Within Lettuce Plant Canopy by Employing Double-Channel Ventilation Cultivation System: Simulation and Experiment Study

Agronomy
In greenhouse and plant factory production, improper design of the ventilation system and increasing scales will lead to a stagnant airflow zone, which could inhibit plant growth and induce physiological disease, such as tipburn.
