We particularly investigated the influence of background gas conditions (N<sub>2</sub>/O<sub>2</sub> ratio) on the droplet number concentration, droplet size distribution, and the estimation of OH production in droplets by a chemical probe method using disodium terephthalate (NaTA) as the treatment solution. Furthermore, we analyzed changes in the plasma emission spectrum at the Taylor cone tip. The plasma emission and the shape of the Taylor cone varied with O<sub>2</sub> concentration, which significantly affected the droplet number concentration. These changes were evaluated using two stabilization indices that consider the inhibition of electrostatic spraying by discharge and the spray duration, thereby revealing the macroscopic droplet spraying process. When droplets were exposed to the treatment solution, the detected OH amount increased with increasing O<sub>2</sub> concentration. The detected OH is likely contained within the droplets, and despite the droplet transport time being much longer than the OH lifetime, OH was detected, suggesting that OH may have been regenerated within the droplets during their transport. It is likely that OH radicals are mainly generated through the peroxone process, which involves the reaction between O<sub>3</sub> and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>). This can be explained by the fact that the O<sub>2</sub> concentration dependence of the gas-phase O<sub>3</sub> concentration shows a similar trend to that of the HTA concentration.</p></div>","PeriodicalId":734,"journal":{"name":"Plasma Chemistry and Plasma Processing","volume":"46 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147341481","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}

Researchers have tried using ns-pulsed or pulse-modulated AC power supplies to reduce gas temperature and enhance efficiency. However, ns-pulsed overvoltage breakdown facilitates quenching particles that accelerate O<sub>3</sub> decomposition, while pulse-modulated AC’s non-short discharge duration reduces cooling efficiency. Additionally, the exorbitant price of high-frequency ns-pulse power supplies diminishes overall system efficiency. This work proposes a novel pulsed AC power supply to circumvent these limitations. The cost of this supply is comparable to traditional continuous AC power supplies. By shortening the discharge duration while suppressing quenching particles, it achieves an ultrahigh O<sub>3</sub> synthesis energy efficiency of 1020 ± 186 g/kWh. Compared to continuous AC-driven discharge, it reduces power consumption by 68–94%, rotational temperature by 118–161 K, and the overall intensities of quenching transient particles of OH by 19–23% and N<sub>2</sub>* by 32–42%. These improvements enable high O<sub>3</sub> synthesis efficiency. When generating O<sub>3</sub> at 240–280 ppm, it cuts energy consumption by approximately 94%, and maintains N<sub>2</sub>O proportion at 1.5–2.2%.

By varying the substrate background temperature from 23 °C to 263 °C, the effects on methane conversion efficiency, hydrogen production, and the structural evolution of carbon deposits are evaluated. Plasma properties and reaction dynamics are characterized using Optical Emission Spectroscopy (OES), Residual Gas Analyzer (RGA) or mass spectrometry, and X-ray Photoelectron Spectroscopy (XPS) measurement techniques. Notably, experiments are performed using high-purity methane to specifically isolate substrate-temperature effects. The results obtained show that electron density increases with background temperature up to about 80 °C, after which it saturates. Besides, methane conversion rate improves modestly with rising temperature. However, both the hydrogen and ethylene concentrations in the plasma decrease significantly. This indicates a temperature-induced shift in selectivity toward carbon-rich products. Furthermore, XPS analysis shows a clear structural transition in the carbon films which from hydrogenated amorphous carbon at low temperatures to increasingly graphitic and less oxidized carbon at higher temperatures. Thus, these findings confirm that while higher substrate background temperatures can enhance CH₄ activation and promote graphitic carbon formation, they simultaneously reduce the hydrogen yield. Hence, the temperature control alone in this low-pressure RF-ICP reactor is an ineffective strategy for optimizing hydrogen production under the studied conditions, though it may benefit applications focused on carbon material synthesis.</p></div>","PeriodicalId":734,"journal":{"name":"Plasma Chemistry and Plasma Processing","volume":"46 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147340225","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}

This paper systematically analyzes various plasma system configurations and their key operational parameters that govern processing efficiency. A major highlight of plasma vitrification is the technology’s consistent performance: achieving near-complete destruction of dioxins and reducing the leaching toxicity of heavy metals to levels well below regulatory thresholds.

These applications are primarily based on the biological effects of spatially distributed electric fields and chemically active species in plasma driven by pulsed power generators (PPGs). For such applications, compact PPGs with moderate peak power and repetitive operation were designed and developed to control discharge plasmas and electric field distributions, thereby enabling the selective induction of desired bio-effects at different agricultural phases. A key issue for agro-applications using pulsed electric fields (PEFs) is the creation of multi-reaction fields of plasma and PEFs with precise spatial and temporal control, allowing adaptation across biological scales, i.e., matching the pulse width to the relaxation time. To achieve this, the power semiconductor switching devices such as SiC-MOSFETs were employed in the development of compact PPGs capable of repetitive operation with low energy loss. These compact PPGs were applied in various agricultural phases and optimized in terms of electrical parameters such as applied voltage pulse width, repetition rate, and circuit impedance. In the pre-harvest phase, two approaches were investigated for enhancing plant growth: (i) direct stimulation of plant tissues using PEFs and (ii) indirect stimulation by exposing cultivation media to PEFs or plasmas. The PEFs were applied to mushroom cultivation beds to promote fruit body formation. In hydroponic systems, nanosecond streamer discharges generated in air bubbles under the nutrient solution were used to inactivate pathogenic bacteria, and promote nitrogen fixation, thereby contributing to plant growth. In post-harvest phase, the compact PPGs were developed to drive the plasma reactors for to the rapid decomposition of C₂H₄ to maintain the quality agricultural products.</p></div>","PeriodicalId":734,"journal":{"name":"Plasma Chemistry and Plasma Processing","volume":"46 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11090-026-10645-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147339685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
