This study aims to evaluate the ultrasound-assisted synthesis of silver nanoparticles (AgNPs) based on an aqueous extract Ruta graveolens L. reduce Ag+ Ag0. In addition, biological activity synthesized AgNPs was evaluated against tumor cells. The following parameters were for synthesis: proportion between solution (0.1 mol L-1 Ag+) and R. extract, pH (5, 7, 9), temperature containing ultrasound (US) type (bath probes), US as frequency (37, 80 kHz bath 20 amplitude time application US. order confirm effect, "silent" experiments (without US) performed. Using optimized conditions (US bath, 1 + 5, v v-1, kHz, 70 % amplitude, °C, 9, 25 min sonication time) it possible obtain mean size, PI, zeta potential 30 nm, 0.129, -34.44 mV, respectively. For comparison results, in condition presented 66 0.412, -22.12 lower, more uniform, stable when compared with magnetic stirring. morphology using predominantly spherical monodisperse. cell lines HaCat (keratinocytes), L929 (fibroblasts), B16-F10 (melanoma) different antioxidant measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method.

Physical pretreatments play a crucial role in reducing the recalcitrance of lignocellulosic biomass, facilitating its conversion into fermentable sugars for bioenergy and chemical applications. This study critically reviews physical pretreatment approaches, including mechanical comminution, irradiation (ultrasound, microwave, gamma rays, electron beam), extrusion, pulsed electric field. The discussion covers mechanisms action, operational parameters, energy efficiency, scalability challenges, associated costs. Methods such as ultrasound microwave induce structural changes that enhance enzymatic accessibility, while extrusion combines thermal forces to optimize hydrolysis. Mechanical comminution is most effective during short periods when combined with other techniques overcome limitations high consumption. Innovative fields, show significant potential but face challenges large-scale implementation. provides technical strategic insights developing more aligned economic feasibility industrial sustainability.

Ultrasonic technology has a significant degassing effect and can increase the efficiency of hydrogen production in proton exchange membrane electrolysis water. However, further research is needed to understand its influence mechanism on bubbles. In this work, kinetic analysis performed investigate principle behaviour bubble evolution by applying ultrasonic amplification technique under static flow dynamics cell. The bubbles dynamic aqueous electrolyte solution ultrasound was characterised imaging. results show that state reduces size increases detachment speed compared state, which promotes process evolution, thermal temperature very small be ignored. Ultrasound different effects stages evolution. nucleation stage, cavitation highly reactive radicals such as •OH, H•, etc., mechanical vibration sites, are denser more evenly distributed. growth phase, promote breaking bonds water molecules improve mass transport, bubbles, fluctuating energy positive negative with speed. radius influenced ultrasound. changes pressure, at pressure increases, decreases, changing favours polymerisation leads increased fine streams. contributes actual operation.
