Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

Advanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

A new cavitation model considering inter-bubble action

International Journal of Naval Architecture and Ocean Engineering, 2021
The process of cavitation involves generation, growth, coalescence, and collapse of small bubbles and is tremendously influenced by bubble–bubble interactions.

Segmented Therapeutic Delivery via Acoustic Microbubble Relay

Advanced Intelligent Systems, EarlyView.
An acoustically driven, modular segmented delivery system is presented to overcome mechanical limitations of conventional microcatheters. Oscillating microbubbles generate directional streaming that enables continuous, targeted transport across open, angled segments.

Growth and Collapse of Cavitation Bubbles : Distribution Change of Cavitation Nuclei due to the Collapse of Cavitation Bubbles

Bulletin of JSME, 1984
The growth and collapse of cavitation bubbles are observed in distilled water using a hydro shock tube which alternately generates low The cavitation bubbles pressure and high pressure in the test section. are fragmentized into numerous small bubbles (so called nuclei) after their collapse.

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

Study on the coupling characteristics of different numbers of cavitation bubbles and particle groups in the free domain

Ultrasonics Sonochemistry
In a free field multiphase environment, the coupling between cavitation bubble dynamics and particle groups can markedly reshape local flow structures and thereby influence particle impact risks.

Acoustic cavitation dynamics of bubble clusters near solid wall: A multiphase lattice Boltzmann approach

Ultrasonics Sonochemistry
Understanding the behavior of cavitation bubble clusters in an acoustic field is crucial for advancing the study of acoustic cavitation. This study uses the multi-relaxation time lattice Boltzmann method (MRT-LBM) to simulate the dynamics of cavitation ...

The Effects of Enzyme Pretreatment Extraction on Lipid Recovery With Normal Phase HPLC

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT With the increasing interest in the commercialization of microalgal fermentation‐based products, sustainable and efficient oil extraction methods have been developed for manufacturing and analytical testing. Due to the variability and resilience of micro‐algae cell walls, traditional lipid extraction methods such as Folch and Bligh and Dyer ...

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.
