The paper emphasizes how ultrasonication can accelerate electrochemical processes, improve mass transfer, and reduce overpotentials. Ultrasonication enhances the physical and chemical parameters of US/electrocatalytic processes by decreasing cell voltage and overpotentials while boosting overall energy efficiency. Other ultrasonication hybrid processes, such as sonocatalysis and US/photocatalysis, have demonstrated the potential to use ultrasonication to activate catalysts and increase hydrogen yields. Notwithstanding these progresses, difficulties remain, such as improving the understanding of the mechanisms underlying US-enhanced hydrogen generation; optimizing operating conditions (e.g., frequency, acoustic power, electrode materials, and solution temperature); and studying hydrogen production from non-aqueous solutions.

To address these challenges, we engineered <em>Chlorella vulgaris</em> (Chl) into a biohybrid platform through sequential integration with 5,10,15,20-tetrakis(4-pyridyl)-21H,23H-porphine tetraiodide (TPP) and human serum albumin (HSA) (termed Chl@TPP/HSA) for synergistic photo-sonodynamic immunotherapy.

Results showed that ultrasonic pretreatment did not alter cellulose crystallinity type but reduced crystallinity and free hydroxyl content, while increasing mass loss, microfibril angle, and hygroscopic dimensional stability.

Its roots have been used to treat various diseases, including abnormal uterine bleeding, arthritis, and kidney stones. However, its stems are often overlooked and regarded as waste. This study employed response surface methodology to optimize the ultrasonic-assisted extraction (UAE) process for polysaccharides from RCL waste stems (RCLP), and compared energy consumption and carbon emissions with hot water extraction (HWE). The underlying mechanism of UAE for polysaccharide extraction was further explored. Additionally, the physicochemical properties and in vitro activities of RCLP extracted by UAE (UAE-P) and HWE (HWE-P) were evaluated and compared. The results showed that the optimal UAE conditions were as follows: temperature of 52.5 °C, extraction time of 43 min, power of 310 W, and liquid-to-solid ratio of 32 mL/g, yielding 5.97 ± 0.34 % of RCLP.
