In this work, the amplitude and half-width of suprathermal soliton solutions to the nonlinear Schrödinger equation are explored with basis on a deformation parameter of a non-Maxwellian distribution. It is found that the ratio of the square of a normalized phase speed of an ion wave to a normalized electron mass may increase by up to 50% due to intense suprathermal effects. It is also found that the soliton amplitude is generally smaller and that the soliton half-width increases with no limit when suprathermal effects are more intense suggesting a greater propensity for dissipation or instability.

In the environment, as mentioned earlier, the parameters in question are essential for the formation of dust KdV and FKdV solitons, changing the phase shifts, and the interaction process of single, double, triple, and quadruple solitons as well as FKdV solitons. Due to the effects of the relevant parameters in the mesosphere environment, hump-shaped compressive KdV and FKdV solitons are formed, together with both positive and negative phase shifts.

To extend their shelf life, plasma as a novel non-thermal sterilization technology developed in recent years, can be applied to suppress microbial growth. Oregano essential oil (OEO) also exhibits strong antimicrobial activity, but the synergistic effect of plasma and OEO remains poorly studied. In this study, we evaluated the bactericidal effects of plasma and OEO, both individually and in combination, against these four bacterial strains. Nucleic acid and protein absorbance increased by 0.294/0.234 (P20) and 0.249/0.184 (P9). Additionally, conductivity rose by 3.9 and 2.96 ms/cm, respectively. The results indicated that the integrity of the cell membrane was compromised, thus increasing its permeability. The inhibitory effect of OEO was determined by the minimum inhibitory concentration (MIC) and the diameter of the circle of inhibition. The MICs of P20, P9, P6 and P2 were 15.6, 15.6, 31.2, and 62.5 mg/mL, respectively. The concentration of OEO was directly proportional to the diameter of the circle of inhibition, and plasma binding with OEO showed a better inhibitory effect. The combination of plasma and OEO showed better bacterial inhibition, with P20, P9 and P6 being able to completely inhibit bacterial growth after 120 s of treatment, whereas P2 was completely sterilized at 35 kV for 120 s.</p>\u0000 </div>","PeriodicalId":10700,"journal":{"name":"Contributions to Plasma Physics","volume":"66 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331537","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}

The simulation demonstrated that, concerning the electron temperature, the two divertor plates are detached at higher density while at lower density, the HFS plate is considered as ‘attached plate’.
