A new empirical method for estimating the high-pressure melting temperatures of solids: NaCl as an example

open access: yes, 2001
Thermal pressure along with its temperature dependence has been used to calculate the melting temperatures of solids under high pressures. Compared with the reference volume (300 K), a critical melting volume corresponding to the melting point is ...

Laser-induced melting of two-dimensional dusty plasma system in RF discharge

open access: yesScientific Reports, 2021
We present a detailed analysis of experimental study, which shows clear evidence of a two-stage melting process of a quasi-two-dimensional dusty plasma system in a high-frequency gas discharge.

Alignments of a Microparticle Pair in a Glow Discharge

open access: yesMolecules, 2021
Stability of a vertically aligned microparticle pair in a stratified glow DC discharge is experimentally investigated. Using laser perturbations, it is shown that, for the same discharge parameters, a pair of microparticles can be suspended in two stable

3D Active Brownian Motion of Single Dust Particles Induced by a Laser in a DC Glow Discharge

open access: yesMolecules, 2023
The active Brownian motion of single dust particles of various types in the 3D electrostatic DC discharge trap under the action of laser radiation is studied experimentally. Spherical dust particles with a homogeneous surface, as well as Janus particles,

Experimental evolution of active Brownian grains driven by quantum effects in superfluid helium

open access: yesScientific Reports, 2022
Complex structures, consisting of a large number of interacting subsystems, have the ability to self-organize and evolve, when the scattering of energy coming from theĀ outside ensures the maintenance of stationary ordered structures with an entropy less ...

The Period of Ignition Delay for Methane-Air Mixture with Hydrogen and Ethylene Additives

open access: yesApplied Sciences, 2021
The article is devoted to estimating the intensifying efficiency of methane-air ignition by adding a small amount of hydrogen and/or ethylene. It presents features of the experimental determination of the ignition delay period for fuel-air mixtures using
