Ultrasonication followed by aqueous two-phase system for extraction, on-site modification and isolation of microalgal starch with reduced digestibility
Ultrason Sonochem. 2024 Apr 29;106:106891. doi: 10.1016/j.ultsonch.2024.106891. Online ahead of print.ABSTRACTMicroalgae are new and sustainable sources of starch with higher productivity and flexible production modes than conventional terrestrial crops, but the downstream processes need further development. Here, ultrasonication (with power of 200 W or 300 W and duration of 10, 15, 20, or 25 min) was applied to simultaneously extract and modify starch from a marine microalga Tetraselmis subcordiformis for reducing the digestibility, and an aqueous two-phase system (ATPS) of ethanol/NaH2PO4 was then used to isolate the sta...

Microbubble-enhanced transcranial MR-guided focused ultrasound brain hyperthermia: heating mechanism investigation using finite element method
Ultrason Sonochem. 2024 Apr 27:106889. doi: 10.1016/j.ultsonch.2024.106889. Online ahead of print.ABSTRACTRecently, our group developed a synergistic brain drug delivery method to achieve simultaneous transcranial hyperthermia and localized blood-brain barrier opening via MR-guided focused ultrasound (MRgFUS). In a rodent model, we demonstrated that the ultrasound power required for transcranial MRgFUS hyperthermia was significantly reduced by injecting microbubbles (MBs). However, the specific mechanisms underlying the power reduction caused by MBs remain unclear. The present study aims to elucidate the mechanisms of MB-e...

High potential extracts from cocoa byproducts through sonotrode optimal extraction and a comprehensive characterization
Ultrason Sonochem. 2024 Apr 26;106:106887. doi: 10.1016/j.ultsonch.2024.106887. Online ahead of print.ABSTRACTCocoa pod husk (CPH) and cocoa bean shell (CBS) are by-products obtained during pre-processing and processing of cocoa beans. Several bioactive compounds have been identified in these by-products that can be used for commercial applications as a way to promote the circular economy. Therefore, the objective of this paper was to recover bioactive compounds from CPH and CBS by sonoextraction process, to determine the type, content, and antioxidant activity in optimized extracts. To achieve our purpose, an optimization...

Continuous motion of particles attached to cavitation bubbles
Ultrason Sonochem. 2024 Apr 28:106888. doi: 10.1016/j.ultsonch.2024.106888. Online ahead of print.ABSTRACTMicrobubble-mediated therapeutic gene or drug delivery is a promising strategy for various cardiovascular diseases (CVDs), but the efficiency and precision need to be improved. Here, we propose a cavitation bubble-driven drug delivery strategy that can be applied to CVDs. A bubble-pulse-driving theory was proposed, and the formula of time-averaged thrust driven by bubble pulses was derived. The continuous motion of particles propelled by cavitation bubbles in the ultrasonic field is investigated experimentally by high-...

Tetracycline degradation by dual-frequency ultrasound combined with peroxymonosulfate
Ultrason Sonochem. 2024 Apr 27;106:106886. doi: 10.1016/j.ultsonch.2024.106886. Online ahead of print.ABSTRACTTetracycline has received a great deal of interest for the harmful effects of substance abuse on ecosystems and humanity. The effects of different processes on the degradation of tetracycline were compared, with dual-frequency ultrasound (DFUS) in combination with peroxymonosulfate (PMS) being the most effective for the tetracycline degradation. Free radical scavenging experiments showed that O2∙-,SO4∙- and •OH were the main reactive radicals in the degradation of tetracycline. According to the major intermed...

A new model for bubble cluster dynamics in a viscoelastic media
Ultrason Sonochem. 2024 Apr 27:106890. doi: 10.1016/j.ultsonch.2024.106890. Online ahead of print.ABSTRACTBubble cluster dynamics in viscoelastic media is instructive for ultrasound diagnosis and therapy. In this paper, we propose a statistical model for bubble cluster dynamics in viscoelastic media considering the radius distribution of bubble nuclei. By investigating and comparing the response for a bubble in three conditions: single bubble; multi-bubble with the same radius; multi-bubble with different radius, the following rules are found: The promotion or suppression of the bubble cluster on the bubble vibration is no...

Ultrason Sonochem. 2024 Apr 23;106:106885. doi: 10.1016/j.ultsonch.2024.106885. Online ahead of print.ABSTRACTThis research designed and developed an ultrasonic reactor for a fast and on demand production of cold brew coffee, remarkably reducing the brewing time from 24 h to less than 3 min. The technology was engineered by utilizing resonance to induce ultrasonic waves around the walls of the brewing basket of an espresso machine. The sound transmission system comprised a transducer, a horn and a brewing basket. This arrangement transformed the coffee basket into an effective sonoreactor that injected sound waves at multi...
