Ultrason Sonochem. 2022 Nov 23;91:106236. doi: 10.1016/j.ultsonch.2022.106236. Online ahead of print.ABSTRACTMetribuzin is an herbicide that easily contaminates ground and surface water. Herein, La-doped ZnFe layered double hydroxide (LDH) was synthesized for the first time and used for the degradation of metribuzin via ultrasonic (US) assisted peroxydisulfate (PDS) activation. The synthesized LDH had a lamellar structure, an average thickness of 26 nm, and showed mesoporous characteristics, including specific surface area 110.93 m2 g-1, pore volume 0.27 cm3 g-1, and pore diameter 9.67 nm. The degradation efficiency of the...

Penetration of hydroxyl radicals in the aqueous phase surrounding a cavitation bubble
Ultrason Sonochem. 2022 Nov 24;91:106235. doi: 10.1016/j.ultsonch.2022.106235. Online ahead of print.ABSTRACTIn the sonochemical degradation of nonvolatile compounds, the free radicals must be delivered into the aqueous solution from the cavitation bubble to initiate reduction-oxidation reactions. The penetration depth in the liquid becomes an important parameter that influences the radical delivery efficiency and eventual treatment performance. However, the transport of radicals in the liquid phase is not well understood yet. In this paper, we focus on the most reactive OH radical and numerically simulate its penetration ...

Low-frequency ultrasonic treatment: A potential strategy to improve the flavor of fresh watermelon juice
Ultrason Sonochem. 2022 Nov 23;91:106238. doi: 10.1016/j.ultsonch.2022.106238. Online ahead of print.ABSTRACTA molecular sensory science approach was used to explore the effects of ultrasonic treatment on aroma compounds of watermelon juice. Watermelon juice was submitted to ultrasonic power at 325 W for 20 min. Ultrasonic treatment reduced odor related to cucumber and green descriptors, whilst significantly improved odors related to sweet, floral, and fruity descriptors, thus contributing to the overall flavor of watermelon juice. Compared with untreated watermelon juice, the amount and concentration of volatile compounds...

Fabrication of icariin-soymilk nanoparticles with ultrasound-assisted treatment
Ultrason Sonochem. 2022 Nov 19;91:106230. doi: 10.1016/j.ultsonch.2022.106230. Online ahead of print.ABSTRACTUltrasound is effective to fabricate nanocomplex. Soymilk is a natural nanocarrier with good compatibility. However, information about soymilk-nutraceuticals nanocomplex is limited. In this work, soymilk was used to encapsulate icariin, a well known nutraceutical with poor bioavailability. The effect of ultrasound on the quality of icariin-soymilk nanocomplexes (ISNCs) was investigated. Ultrasound could reduce the particle size, improve the surface hydrophobicity and change the microstructure of soymilk. With increa...

Combined transcriptome and metabolome analyses reveal the mechanisms of ultrasonication improvement of brown rice germination
This study investigated the effects of ultrasonication treatment on the germination rate of brown rice. Brown rice grains were subjected to ultrasound (40 kHz/30 min) and then incubated for 36 h at 37 °C to germinate the seeds. Ultrasonic treatment increased the germination rate of brown rice by up to ∼28 % at 30 h. Transcriptomic and metabolomic analyses were performed to explore the mechanisms underlying the effect of ultrasonic treatment on the brown rice germination rate. Comparing the treated and control check samples, 867 differentially expressed genes (DEGs) were identified, including 638 upregulated and 229 down...
