Inside‐Outside ROS Therapeutic Strategy Based on Piezoelectric Nano‐Urchin for Drug‐Resistant Bacteria Biofilm Infections

Advanced Science, EarlyView.
The contribution of this study lies not only in enabling effective treatment of drug‐resistant biofilm infections, but also in establishing a transferable therapeutic paradigm: Ultrasound‐triggered mechanical forces synergistically enhance piezoelectric polarization and nanozyme activity, driving functional ROS generation inside and outside biofilms ...

Bridged h‐BN Nanosheets Coatings: Simultaneous Shielding Atomic‐Oxygen Irradiation and Achieving Superior Friction Performance

Advanced Science, EarlyView.
ABSTRACT To confront extreme space environments, a combination of inorganic and organic coatings can provide a pathway for offering highly durable radiation resistance and anti‐friction simultaneously. Herein, a strong interfacial 3D hydrogen‐bonding network is designed to create robust hexagonal boron nitride (h‐BN) based polymer coatings with ...

Pyridine‐Isomerism‐Driven Spin Engineering at a COP‐Fe3O4 Interface for High‐Performance Oxygen Reduction Electrocatalysis

Advanced Energy Materials, EarlyView.
Strategically adjusting the pyridine nitrogen position in the polymer matrix (pyridine isomerism) intensifies its interaction with embedded Fe3O4 nanocrystals. This enhanced interaction induces a spin‐state transition in Fe from low‐spin to intermediate‐spin, accompanied by refined d‐orbital properties.

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Optimization of Structural Parameters and Cavitation Suppression in Control Valves Based on P-WOA [PDF]

Journal of Applied Fluid Mechanics
A control valve is a critical component in water supply systems, controlling pressure, flow, and direction. However, cavitation, caused by low pressure in the valve cavity, disrupts flow and leads to cavitation damage, vibration, and noise, affecting ...

Sustainable Palm Oil Extraction and Trends in the Use of Green Technologies: State‐of‐the‐Art and Future Directions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Palm oil, which is extracted from the mesocarp of the fruit of the Elaeis guineensis Jacq. palm tree, is the most widely produced vegetable oil in the world. The extraction of this substance typically utilizes the conventional pressing method, a technique that is advantageous due to its low operating cost and simplified process.
