Additionally, plastic debris serves as a source of allochthonous carbon to marine ecosystems — a factor that has only drawn scientific attention recently. Herein, we synthesize recent evidence about this new form of plastic carbon in the ocean by addressing it as three components: particulate organic carbon of plastic (<em>pPOC</em>), dissolved organic carbon leaching from plastic (<em>pDOC</em>), and biogenic organic carbon of plastic-attached biofilm (<em>pBOC</em>). Current estimates of <em>pPOC</em> and <em>pDOC</em> account for only a modest fraction of natural carbon pool in the ocean, but their portions are expected to increase. <em>pDOC</em> is highly heterogenous, varying by polymer types, and has been shown to influence seawater biogeochemistry as well as the structure and function of microbial communities. Furthermore, biofilm biomass colonizing on plastic debris can utilize the <em>pP</em>OC and <em>pDOC</em> as carbon sources. Current evidences proved the incorporation of plastic carbon into microbial biomass, which consequently affects the carbon and nitrogen cycling. Given these emerging insights, we further suggest specific research questions aimed at stimulating research on the nature, dynamics, and role of plastic carbon in the ocean.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101101"},"PeriodicalIF":8.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240723","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}

In this sense, ultrasound-assisted extraction (UAE) has emerged as a promising technology for fast and efficient extraction of natural products without high organic solvent consumption. However, most studies on UAE are focused on laboratory scale. In order for this technology to be suitable for industrial applications, more pilot studies need to be developed and discussed. In this sense, this review aimed to address scale-up applications of UAE of natural products developed from 2019 to the first semester of 2024. Applications involving hydrodynamic cavitation were not included in this review. Key parameters related to ultrasound were addressed, such as reactor configuration, process type (batch or continuous), frequency, and others. Furthermore, the major challenges associated with the upscaling of UAE, as well as current trends and future perspectives were discussed. It was observed that flow cells were the main reactor type used in scale-up UAE of natural products and that flow-through was the main operation mode. The use of these devices enabled processing of higher sample volumes, possibly due to more homogeneous energy distribution in the reactor. Hence, further enhancements in this area should be expected. Furthermore, phenolic compounds were the main targets of extraction and low frequencies (<100 kHz) were used. However, a challenge remains regarding the lack of essential information in several publications, which makes comparison between studies difficult, as well as their reproduction. Nevertheless, scale-up UAE of natural products is a promising research area.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101120"},"PeriodicalIF":8.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143682639","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. This review aims at highlighting the latest works on biomass pretreatment under chemically or enzymatically assisted ultrasonic irradiation on both lab and pilot/semi-industrial scales together with future directions to enable scale-up of ultrasonic processes for biomass valorization.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101124"},"PeriodicalIF":8.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768270","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}

Regarding current research on water treatment techniques, there is a clear need to study such systems under realistic environmental conditions. In this review, we aim to show that X-ray spectroscopic techniques are uniquely positioned to provide such information by obtaining detailed molecular insight into phenomena relevant to water research.
