However, understanding the mechanical properties of materials undergoing CAP treatment is of great importance, particularly for applications involving changes in material properties. This study aims to utilize CAP as an excitation device for assessing the mechanical properties of a polymethyl methacrylate (PMMA) sample. CAP was employed to induce vibrations on a PMMA sample around its resonance frequency, and the resulting vibrations were measured by a scanning laser doppler vibrometer. The elastic modulus of the PMMA sample was then calculated based on the stress and strain profiles obtained from the measured vibrations. The obtained elastic modulus value of 4.87 GPa showed excellent agreement with the 4.83 GPa value obtained using other excitation devices, indicating the reliability of CAP in mechanical characterization. This study is the first step toward potential applications that can break new ground in the use of CAP in monitoring and characterization of mechanical properties during CAP treatment (e.g. surface treatment), paving the way for enhanced control and optimization of CAP-based processes in various applications.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":734,"journal":{"name":"Plasma Chemistry and Plasma Processing","volume":"45 2","pages":"503 - 514"},"PeriodicalIF":2.6,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 3-way full factorial design was applied to evaluate the influence of treatment time, power, and airflow rate on degradation efficiency. Initial tests on dyes such as crystal violet, congo red, methylene blue, and indigo confirmed the efficacy of the plasma jet, with degradation efficiencies of 96.3%, 86.3%, 93.4%, and 97.8%, respectively, within treatment times ranging from 8 to 60 min. For denim industry wastewater, plasma treatment resulted in notable reductions in chemical oxygen demand (COD), with 35.0% removal for virgin wastewater and 15.9% for industry-treated wastewater. Total organic carbon removal increased by 42.6% for virgin wastewater and 18.2% for industry-treated wastewater, indicating substantial mineralization. Toxicity analysis showed that plasma-treated wastewater supported freshwater algae growth, suggesting a non-toxic nature and enrichment with nitrogen-based nutrients. Regression analysis and optimization identified plasma treatment time and power as the key factors in maximizing COD removal. Under optimal conditions, COD removal reached 97.65% for virgin wastewater and 98.1% for industry-treated wastewater.

Based on the forward reaction system, we present an energy level diagram of the reaction path, which serves as a foundation for deeper comprehension of the impact of the activated KrCl and Kr<sub>2</sub>Cl chemical processes on the production and intensification of radiation at 222 nm.

The density of excited KrCl particles decreases by 7.6% and power efficiency rises by 1.7% lift with every 20 mbar increment for a higher probability of inelastic collision. A greater proportion of chlorine increases the probability of a reaction with chlorine, inhibiting the creation of radiation particles and enhancing the quenching of radiation reactions. The action balances the numerical concentrations of Kr and Cl and strongly suppresses the excited Kr<sub>2</sub>Cl particles. The simulation demonstrates that there are negligible disturbance on power supply efficiency as the proportion of 325 nm radiation in the spectrum decreases from 6 to 1%.

This review would provide an overview on the latest advancement of NTP applications for food crop seeds, considering the different food crop groups, and summarizes the mechanism of how NTP improves germination and growth. Results vary based on seed type, plasma setup, and source, such as direct glow plasma or plasma-activated water (PAW). In direct glow plasma, reactive species induce morphological changes by bombarding seed surfaces with ions and radicals. PAW, on the other hand, promotes seed germination through reactive oxygen and nitrogen species (RONS) present in the water. Regardless of treatment sources, RONS ions also play a crucial role in modifying seed morphology, activating antioxidant enzymes, and influencing hormonal pathways to stimulate growth processes while suppressing inhibitory signals. NTP treatment shows promising potential in plasma agriculture, but excessive exposure may adversely affect plant growth. Additionally, NTP induces epigenetic changes, such as DNA methylation, which regulates stress-related genes, further supporting seed performance. Despite these advancements, critical knowledge gaps remain, including the need for standardized plasma energy evaluations, long-term yield impact, and safety validations for food produced from plasma-treated seeds. Future research must address these aspects to ensure the widespread, sustainable application of NTP technology in agriculture.</p></div>","PeriodicalId":734,"journal":{"name":"Plasma Chemistry and Plasma Processing","volume":"45 1","pages":"421 - 462"},"PeriodicalIF":2.6,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142941053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
