Summary: The propagation of dust acoustic solitary waves (DASWs) in a magnetized dusty plasma comprising of negatively charged dust particles, nonthermal ions and nonthermal electrons was investigated. The Korteweg-de-Vries (K-dV) equation was derived using reductive perturbation method. It was found that the basic structures of DASWs are influenced by nonthermal ions and nonthermal electrons. Both compressive and rarefactive DASWs exist in such dusty plasma. The nonthermality parameter of ions and electrons affects the non-linear wave phase velocity, with ions having a greater effect than electrons. The angle between the external magnetic field and the wave propagation direction strongly influences the amplitude and width of DASWs. The magnetic field only affects the width and not the amplitude of DASWs.

Summary: In this paper, the behavior of dust acoustic waves in a nonconstant dust temperature plasma was investigated. The model considered negatively charged dust particles and thermal ions. The reductive perturbation technique was applied and the novelty of this study lies in the nonuniformity of plasma temperature. The nonconstancy of temperature was introduced as a first-order perturbation in the calculations, leading to the derivation of the modified Korteweg-de Vries (mKdV) equation. The solution of the modified KdV equation revealed the changes in soliton shape when the wave propagated in a perturbation plasma with varying temperature. Effects such as soliton deformation and amplitude reduction were observed when encountering regions with different temperatures. This research contributes to a better understanding of wave behavior in real plasmas with nonuniform temperature.

Summary: The influence of polarization force, trapped degenerate electrons, and nonthermal ions on the propagation characteristics of dust acoustic solitary waves (DASWs) in a magnetized dusty plasma is investigated. The reductive perturbation approach has been used to derive the extended Zakharov-Kuznetsov (eZK) equation and study the characteristics of DASWs. Pulse stability has also been analyzed, and the impact of different plasma parameters on the growth rate and instability criteria of DASWs has been studied. This investigation is important for explaining nonlinear structures in ultra-dense degenerate plasma media found in astrophysical compact objects and high-density plasma experiments.

Summary: This paper investigates the modes of dust-ion-acoustic waves (DIAWs) in a viscous dusty plasma containing Kappa-distributed electrons, positive warm viscous ions, and constant negatively charged dust grains with viscosity, by theoretical and numerical methods. The derivations and basic features of shock and solitary waves are analyzed based on various plasma parameters. A phase portrait is obtained using the dynamical equation from the Korteweg-de Vries equation, and the position of saddle points and centers are discussed. This research is significant for understanding the nature of DIAWs in both astrophysical and laboratory plasma.

Summary: In this study, Dust-acoustic waves (DAWs) are investigated in an electrostatic self-gravitating dusty plasma. The electrons and ions are modeled using a nonextensive q-distribution function, while the dust particles follow a Maxwellian distribution. The plasma dispersion relation and instability growth rate are derived using a Vlasov-Poisson set of equations. The effects of various parameters, such as self-gravitation, nonextensivity, dust concentration, and streaming speed, on the wave frequency and growth rate are examined. The applicability of the results in interstellar dust clouds is also discussed.

Summary: In this paper, the non-linear propagation of dust ion-acoustic waves in a complex dusty plasma is fully analyzed using bifurcation techniques and numerical simulations. A dynamical system capturing the main features of traveling wave solutions and transition between nonlinear modes is derived. The study reveals the existence domains of stability regions for different ranges of electron nonextensivity and dust concentration. The motion dynamics of low-frequency dust ion-acoustic traveling waves undergoes a transcritical bifurcation at critical points of nonextensivity parameter and dust concentration, resulting in a switch of stability. A new kind of solitary structure characterized by transcritical bifurcation parameters with half-stable equilibrium points is observed. The effects of nonextensive parameter and dust polarity on the transition between nonlinear traveling waves are investigated.

Summary: The study found that a DC magnetic field in the range of 0-180 mT has significant effects on the properties of cobalt oxide nanoparticles synthesized by pulse laser ablation in distilled water. Increasing the magnetic field strength during the ablation process resulted in a noticeable decrease in the size of the nanoparticles, leading to a shift in their excitonic absorption peaks. By applying an external magnetic field, crystalline structure nanoparticles were obtained, while in the absence of an external magnetic field, only amorphous phase nanoparticles were produced. The results suggest that an external magnetic field is a strong tool for controlling the properties of ferromagnetic nanoparticles produced by laser ablation.

Summary: Mn3O4 (hausmannite) nanoparticles were synthesized using the pulsed laser ablation method in a liquid environment and deposited on an aluminum substrate using the direct current electrophoretic deposition technique. The effects of deposition voltage and time on the film characteristics were studied using various diagnostic methods. The formation of stable manganese oxide nanoparticles with the chemical formula Mn3O4 was confirmed by X-ray diffraction, and the morphology of the films changed from spherical nanoparticles to nanosheets with increasing deposition voltage. The roughness, average particle size, and thickness of the deposited thin films could be controlled by the applied voltage and deposition time, as observed by AFM studies. Additionally, the reflectance patterns of the samples depended on the material of the thin films and substrates, as well as the size of particles in the film structure, as indicated by UV-Vis-NIR spectroscopy results.

Summary: The experiment investigates the influence of a transverse magnetic field on plasma plume produced by pulsed laser ablation as well as the structural and optical properties of nickel oxide nanoparticles. The strength of the external magnetic field can be controlled by the distance between magnets. Results show that increasing the strength of the magnetic field leads to an increase in XRD peak intensity and a decrease in particle size. Additionally, the magnetic field causes cyclotron motion of charged particles in the plasma plume, increasing their energy and reducing agglomeration.
