Acoustic cavitation exploits high-frequency ultrasonic waves to generate transient and stable bubbles, leading to localized high temperatures, pressures, and reactive species formation. Hydrodynamic cavitation, achieved through fluidic devices, such as Venturi tubes and vortex diodes, generates cavities under controlled low-pressure zones, providing scalable solutions for large-scale operations. This study critically examines the industrial viability of cavitation technologies, emphasizing their unique ability to combine mechanical, thermal, and chemical energy release. A detailed comparative analysis reveals the limitations of acoustic cavitation, including energy attenuation and equipment wear, against the superior scalability of hydrodynamic systems. Key challenges, such as enhancing hydroxyl radical yield, reducing operational costs, and improving system robustness, are explored alongside potential synergies with complementary technologies, like advanced oxidation processes and photocatalysis. Emerging industrial implementations, including biogas enhancement and chemical processing, underscore the evolving landscape of cavitation-based innovations. This work highlights the necessity for multidisciplinary strategies, integrating experimental, computational, and engineering perspectives to advance cavitation technology. By addressing scalability and cost-effectiveness, cavitation systems can unlock transformative opportunities for sustainable industrial applications, aligning with global environmental and economic imperatives.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101129"},"PeriodicalIF":8.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143799289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, due to their extensive usage, per- and polyfluoroalkyl substances (PFAS) and endocrine-disrupting chemicals (EDCs) have emerged as significant global concerns due to their pervasive presence and substantial accumulation in aquatic ecosystems. Research to date has primarily focused on these contaminants in isolation, leaving the interactions and cumulative effects among MPs, PFAS, and EDCs (trifecta) relatively unexamined. We elucidate the probable interaction mechanisms among these three categories of contaminants and to analyze their combined toxicity, as well as the existing regulatory frameworks and policies applicable to them. Our findings indicate that the sorption of EDCs and PFAS onto MPs is predominantly governed by hydrophobic and electrostatic forces and is sensitive to various environmental parameters, including pH, salinity, temperature, and dissolved organic matter. The interactions among these contaminants are intricate, encompassing mechanisms such as cation-π bonding and biofilm formation, all of which influence the dynamics of sorption. The synergistic effects of MPs in conjunction with co-contaminants, such as PFAS and EDCs, exacerbate toxicity, promote bioaccumulation, and elevate health risks for both aquatic organisms and mammals, typically contingent upon factors such as exposure duration, dosage, and environmental conditions. In conclusion, we underscore that while significant advancements have been achieved, considerable efforts are still required to address regulatory deficiencies and to advance legislation aimed at mitigating the impact of persistent pollutants.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101126"},"PeriodicalIF":8.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143799288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The valorization of lignocellulose, a virtually endless resource, implies the selective extraction of the three main components, cellulose, hemicellulose and lignin, to then treat them separately. Among the methods of pretreatment/preferential dissolution of biomass, low-frequency ultrasound (US) has shown to be a promising disruptive technology. Eager to be combined with physical technologies, chemical agents or enzymes, many examples under low-frequency US exist at the lab scale. However, examples of scaling-up of US-processing of biomass remain yet scarce. It appears quite challenging to design ultrasonic equipment that allows sufficient and homogeneous energy powers in large volumes, although recent pioneering work shows considerable progress.
