This system encompasses ions, electrons, positively and negatively charged dust particles, distributed in accordance with a superthermal distribution. Employing the reductive perturbation technique (RPT), the Gardner equation (GE) is derived from the fundamental hydrodynamical model equations. The multi-solitons of the GE are synthesized utilizing the Hirota bilinear method (HBM), which further facilitates the exploration of breather solutions via the appropriate selection of complex wave numbers. The system exhibits both compressive and rarefactive multi-solitons. Moreover, the behavior of breather structures varies depending on associated plasma parameters; occasionally, they overlap, while at other times, they remain entirely disjoint. This research holds relevance for investigating the propagation of finite-amplitude waves in natural phenomena such as the atmosphere, oceans, optic fibers, and signal processing.\u0000</p><p>Figures display the interaction between two-solitons (a), and breather structures (b), of the Gardner equation in dusty plasma with polarized force for the parameter values <span>(k_i = 5, k_e = 2.5, mu _i = 0.7, mu _e = 0.3, mu = 10, rho = 1.01, sigma _i = 0.1, R = 0.5, Z = 0.01)</span>, respectively.

We studied this emission for the surface dielectric barrier discharge in the air. We used the discharge with one strip-driven electrode and a sinusoidal driving voltage of frequencies 5 and 10 kHz. From the spectra of emitted waves in the frequency band up to 3 GHz, we found that this type of discharge emits the radiation of frequencies below 500 MHz. In this frequency band, we focused on the effect of the driving voltage frequency and driven electrode material on the spectra of these waves. It was found that emitted radiation is distributed in several packages of frequencies, and an increase in the driving voltage frequency or voltage increases the power level of emitted radiation. Compared with the radiation spectrum of the discharge with an aluminium-driven electrode in the spectrum of the discharge with the copper-driven electrode, new peaks of various power levels and the shift of certain radiation frequencies to lower values appear. To understand the underlying mechanism of the discharge electromagnetic waves emission, we focused on the correlation between the electric component of emitted EMWs and the discharge electrical parameters as a function of time and discharge voltage.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":789,"journal":{"name":"The European Physical Journal D","volume":"78 7","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epjd/s10053-024-00887-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141551915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The crystal structure and morphology of the Ag nanoparticles printed on the glass substrate were characterized by X-ray diffraction (XRD), the field emission scanning electron microscope (FESEM), and the atomic force microscope (AFM). The XRD patterns confirm Ag nanostructure deposition on the glass. FESEM results show that Ag nanoparticles’ are almost spherical in shape and by increasing the applied voltages, the Ag nanoparticles' size and density increases, and AFM images confirm the results of FESEM images. Rhodamine B with various concentrations was employed to determine the surface-enhanced Raman scattering (SERS) performance of Ag nanoparticles printed on the glass. It shows high sensitivity for Ag layers created by plasma to a threshold that even for the lower concentrations of 10<sup>−10</sup>M, Rhodamine B is still detectable. There was the optimum SERS effect at a 7 kV voltage. Also, the plasma-printed Ag layers are able to detect methylene blue, usually used as a fungicide in fish ponds and aquariums, even in low concentrations of 10<sup>−9</sup>M.
