Their toxicity, bioaccumulation, and oxidative stress disrupt ecosystems, demanding an urgent need for risk monitoring. A thorough understanding of the extent of the problem and the need for an amicable solution utilizing nanobioengineered materials is highly desired owing to their unique properties, such as tailored surface chemistry, specificity, and high sensitivity. These properties allow them to interact with the contaminants at the molecular level, making them suitable for MNP detection. Moreover, they have the potential to overcome challenges, such as the complex environmental matrices, data reproducibility, and inefficient sampling faced by pre-existing techniques, making them a promising tool for detecting MNPs. This review presents the importance of next-generation nanobioengineered materials for developing biosensors for MNP detection, and efforts have also been directed to enrich the awareness of the researchers working in this domain by providing innovative solutions to challenges faced by pre-existing techniques.

The use of ultrasound in electrochemical processes such as water electrolysis can lead to an energy efficiency enhancement in the range of 2–25% in low-temperature water electrolysers (LT-WE). However, this improvement greatly depends upon several factors such as the cell reactor design, the ultrasonic frequency, the transmitted acoustic power, and the distance between the ultrasonic transducer and the electrode. The main objectives of this review are to highlight recent advancements in using power ultrasound in water electrolysis and shed some light on possible commercial development by addressing the fundamental obstacles that lie in this technology. Several research works have highlighted that the efficiency improvement in ultrasound-aided water electrolysis is principally due to the gas bubble removal from the electrode surface, which ultimately reduces the ohmic resistance of the electrolytic cell. However, even with the observed higher efficiencies from the <em>sonoelectrolysers</em> for hydrogen production in R&D labs, this technology still faces challenges for further development due to the efficiency in competing with commercial LT-WEs, which are already in the range of 60–70%. If <em>sonoelectrolysers</em> are to succeed for commercial development and large-scale industrial applications, they would need to achieve overall efficiency much higher than current commercial LT-WEs.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101122"},"PeriodicalIF":8.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739240","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}

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}
