This study aims to evaluate the cytotoxicity, genotoxicity and mechanisms of human periodontal ligament fibroblasts (hPDLFs) induced by CAP. The antimicrobial effect on Porphyromonas gingivalis (P. gingivalis) was evaluated using the colony-forming unit methods (CFU). Human periodontal ligament fibroblasts were treated with CAP for variable times (1, 2, 4, 8, and 16 min). CCK-8 assays were performed to detect cell viability and flow cytometry was performed to measure the cell cycle and apoptosis. Cell migration ability was determined by scratch assays. The physicochemical properties of plasma activated medium were evaluated, including the pH values, H2O2 and NO levels. DCF-DA staining and analysis were performed to evaluate intracellular ROS levels inside cells using flow cytometry. Immunofluorescence of DNA double-strand breaks (DSBs) marker, phosphorylated γH2AX was used to establish the genotoxicity of plasma. The results showed that CAP has a significant inhibition effect of P. gingivalis after 6 min treatment. It has significantly dose-dependent effects that ranging from increasing cell proliferation to inducing apoptosis. A low doses (1, 2, 4, and 8 min) could enhance the cell proliferation. A high dose (16 min) resulted in the inhibition of cell proliferation (p < 0.01).

In this study, a SNAPT was designed and studied, in order to investigate the effects of discharge current, gas flow rate, and nozzle morphology on the discharge characteristics. The results show that the volt-ampere characteristics of the SNAPT have an increasing curve when the gas flow rate is greater than 4 Nm3/h, and a decreasing curve when the gas flow rate is 3 Nm3/h. This result is related to the position of the arc root, and an arc constriction phenomenon occurs at high current and low gas flow rate. The thermal efficiency of the SNAPT decreases with the increasing current and decreasing gas flow rate, ranging from 69.6 to 82.3% within the experimental parameters. The optical emission spectroscopy results show that there are many active particles inside the plasma. The experimental parameters of the heavy particle temperature of 4851.5 to 9189.3 K and the electron temperature of 7846.9 to 10185.6 K both correspond to the Boltzmann distribution and are close to the local thermodynamic equilibrium state.

In the current work several industry wastes have been tested under discharge plasma environment for their catalytic properties in the removal of HCs from diesel exhaust. To explore the benefit of metal oxide components, present in industry wastes, a new approach was proposed in this work wherein two industrial wastes were blended to form a composite waste which was then powdered and bound to form pellets. Four such composite waste-based pellets, namely red mud + iron tailing, iron tailing + lignite ash, lignite ash + copper slag and red mud + oyster shells, were tested for their catalytic properties under plasma environment. Exhaust emanating from a 6 HP engine is sampled and studied for HC removal in a pulsed plasma reactor embedded with composite wastes. The pellets being porous in nature, studies were also conducted for HC adsorption by cascading composite wastes with plasma alone while treating the exhaust. All the composite wastes exhibited good plasma catalysis in HC removal (58–73%) when compared to that with plasma alone (31%). Further, there is a marked difference between plasma adsorption and plasma catalysis by a factor of 1.75–2.2 indicating synergy between plasma and metal oxides present in composite wastes while catalysing HC removal.</div>","PeriodicalId":734,"journal":{"name":"Plasma Chemistry and Plasma Processing","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140967719","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}

The impact of reactor parameters and gas parameters on the nitrogen fixation reaction was systematically investigated in this study. The findings revealed that the DBGADΦ50 significantly improved the nitrogen fixation effect. At a specific input energy of 2.7 kJ/L, the concentration of NOx generated by the dielectric-boosted gliding arc air discharge was 1.12 times that of the conventional gliding arc discharge (GAD).

In the DBGADΦ50, the NOx concentration was 1.33 times higher than that in the air atmosphere when the added O2 volume fraction reached 30%. Performance can be further enhanced by adding TiO2 catalyst particles to the surface of the quartz dielectric to form a catalyst layer approximately 5 mm thick.
