The conversion of lignocellulosic biomass for biofuels and biorefinery applications is limited due to the cost pretreatment separate or access biomass’s three main usable components, cellulose, hemicellulose, lignin. After pretreatment, each component may be utilized via chemical conversion, hydrolysis, and/or fermentation. In this review we aim first, identify current status-quo knowledge parametric effects ultrasound, second, evaluate potential ultrasound as a fractionation method...
Sonolysis has been proposed as a promising treatment technology to remove per- and polyfluoroalkyl substances (PFASs) from contaminated water. The mechanism of degradation is generally accepted be high temperature pyrolysis at the bubble surface with dependency upon reaction site availability. However, parametric effects ultrasonic system on PFAS are poorly understood, making upscale challenging leading less than optimal use energy. Hence, thorough understanding these could lead improved...
Ultrasound, alone or in combination with natural antimicrobials, is a novel food processing technology of interest to replace traditional decontamination methods, as it milder than classical sterilisation (heat treatment) and maintains desirable sensory characteristics. However, ultrasound efficacy can be affected by structure/composition, well the order which combined treatments are applied. More specifically, target different cell components could result enhanced inactivation if applied...
The degradation of paracetamol, a widely found emerging pharmaceutical contaminant, was investigated under wide range single-frequency and dual-frequency ultrasonic irradiations. For irradiation, plate transducers 22, 98, 200, 300, 400, 500, 760, 850, 1000, 2000 kHz were employed for the coupled with 20 horn in opposing configuration. sonochemical activity quantified using two dosimetry methods to measure yield HO• H2O2 separately, as well sonochemiluminescence measurement. Moreover,...
This work reports the influence of ultrasound alone and combined with ozone for treatment real abattoir wastewater. Three different frequencies were studied (44, 300 1000 kHz) at an applied power 40 W. The injected dose was fixed 71 mg/L time varied from 1 to 60 min. Using alone, kHz only frequency showing a reduction in chemical oxygen demand (COD, 18% reduction) biological (BOD, 50% reduction), while no diminution microbial content measured any studied. Combining ozone, on contrary, led...
A systematic study on the sonocrystallisation of ZIF-8 (zeolitic imidazolate framework-8) in a water-based system was investigated under different mixing speeds, ultrasound frequencies, calorimetric powers and sonication time. Regardless synthesis technique, pure crystals with high BET (Brunauer, Emmett Teller) specific surface area (SSA) can be obtained water after only 5 s. Furthermore, s produced even smaller (~0.08 µm). The type technique applied for producing did not have any...
Ultrasound was shown to enhance pretreatment of lignocellulose for biofuel and biorefinery applications can augment oxidative processes, yet few studies have combined ultrasound with an environment the lignocellulose. In present contribution, a wheat straw using combination two pretreatments, peracetic acid hydrogen peroxide, as well water acetic tested. The experimentation conducted in ultrasonic-microwave reactor comparison silent microwave heating alone. addition, thermal compared...
A comprehensive understanding of the dynamic processes in sonochemical reactions is essential for providing theoretical support and practical guidance ultrasonic industrial applications. The influence acoustic factors (frequency and...
The effects of ultrasound (frequency and pressure amplitude) external parameters (fluid flow rate surface stabilisation) on active sonoluminescence (SL) sonochemical (SC) bubbles were investigated using common characterisation techniques. SL from water, sonochemiluminescence (SCL) luminol solutions iodide dosimetry studied at rates 0, 24, 228 626 mL/min 44, 300 1000 kHz with without stabilisation. An increase in flow, general, decreased SL, SCL caused by a reduction collapse intensity....
This paper reports for the first time development in size and shape of sodium chloride crystals during antisolvent crystallization ethanol under different sonication modes. Sonication using 98 kHz a calorimetric power 6 W was applied either continuously range times (5–90 s) or intermittently (5 s pulse). Under silent conditions, 90 generated with an average 73.8 ± 6.9 μm, comparison to 8.7 2.8 μm continuous sonication. However, it observed that within 5 at beginning crystallization, crystal...
Current literature shows a direct correlation between the sonochemical (SC) process of iodide oxidation and degradation phenol solution. This implies occurs primarily via oxidisation at bubble surface. There is no work present which considers effect fluid flow on process. In this work, parametric analysis 0.1 mM solution dosimetry under conditions was undertaken to determine flow. Frequencies 44, 300 1000 kHz rates 0, 24, 228 626 mL/min were applied with variation power input, air...
