Four different surfactants were used, i.e., hexamine, PEG, PVA, and PVP. The prepared samples were subjected to argon plasma treatment for 20 min with glow discharge (GD) plasma technique. The morphology and structural properties have been analyzed with SEM and XRD, respectively. The optical property has been evaluated and showed higher absorbance in UV-visible light region. Photocatalytic activity of PEG added BiVO4 showed higher degradation for methylene blue dye, i.e., 56% in 180 min under visible light illumination. The result has been further supported by PL and Raman analyses. The BET analysis was used to detect the pore size and specific surface area of the samples. Furthermore, the reusability of the photocatalyst was evaluated by the stability test. The XPS and TEM analyses analyze the composition and crystalline nature of the prepared sample. The GCMS analysis of MB dye degradation has inferred the stability of the sample after dye degradation. The GCMS analysis and reusability test confirm the stability of PG after the photocatalysis process and confirm that the plasma treatment has helped in the stability of PG.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142175276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This device has been characterized by electrical and optical diagnostics to determine its efficacy for biological applications. These characterization results showed that eight-LPM Ar plasma at 16.5-W operating power produces stable plasma with low discharge current. The device was then tested as bactericide on Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. While E. coli could be completely annihilated after 120 s of plasma treatment at a 2-mm distance from plasma tip; inactivation of S. aureus starts after 60 s due to its thicker cell wall and complete annihilation requires 240 s of plasma exposure. Potent bactericidal plasma emission bands, such as OH (~309 nm), N2 (SPS) (~337 nm), and OI (~777.4 nm), have been observed and electron microscopy analysis of bacteria supports cell damage post-plasma treatment. The study indicates that ~4–6 mm away from the plasma tip, the effect of charged particles vanishes but emitted UV and reactive oxygen species (ROS) from CAPP still eradicates bacteria in short exposure time (<8 min). Demonstrating microbial inactivation at a distance underscores the potential for noncontact, remote sterilization applications. This innovative capability opens doors to industries where the maintenance of pristine, germ-free environments is of paramount importance.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142175278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

In order to enhance the electrical contact performance of armature and rail interfaces and achieve armature lightweighting, a novel approach is proposed that combines backpropagation (BP) neural networks with genetic algorithms for optimizing armature structures. Employing Latin hypercube experiments, structural dimension samples were extracted for both flat armatures and convex-arc armatures, and a training dataset was generated through finite element simulations. Mapping models were constructed based on BP neural networks to relate the contact pressure distribution coefficient, maximum stress, mass, and total contact force individually to the armature structural parameters. Incorporating a comprehensive evaluation index denoted as “W” as the fitness function for the genetic algorithm, global optimization of armature size was carried out. The optimized results were subsequently validated through finite element comparative analysis. The outcomes revealed that, following optimization of flat armatures, a 10.4% reduction in mass and a 55.7% decrease in the contact pressure distribution coefficient were achieved. For convex-arc armatures, a 25% reduction in mass and a 46.5% decrease in the contact pressure distribution coefficient were observed. Simultaneously achieving armature lightweighting and improving the uniformity of contact pressure distribution on armature and rail interfaces, this methodology offers a novel perspective and serves as a valuable reference for addressing the optimization of armature structures under complex operating conditions.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142175288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
