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.

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 the 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

Anisotropic Unruh temperatures [PDF]

open access: yes, 2017
The relative entropy between very high-energy localized excitations and the vacuum, where both states are reduced to a spatial region, gives place to a precise definition of a local temperature produced by vacuum entanglement across the boundary.

The Influence of Elevated CO2 Concentrations on the Growth of Various Microalgae Strains

open access: yesPlants, 2023
The influence of elevated CO2 concentrations on the growth and viability of various microalgae strains was studied. Arthrospira platensis, Chlorella ellipsoidea, Chlorella vulgaris, Gloeotila pulchra, and Elliptochloris subsphaerica were tested.

Temperatures of Exploding Nuclei [PDF]

open access: yes, 1998
Breakup temperatures in central collisions of 197Au + 197Au at bombarding energies E/A = 50 to 200 MeV were determined with two methods. Isotope temperatures, deduced from double ratios of hydrogen, helium, and lithium isotopic yields, increase ...

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

Bose condensation at high temperatures [PDF]

open access: yes, 1999
Bose condensation is usually a low temperature phenomenon due to a low particle number density. When the number density is kept large compared to the inverse Compton volume, Bose condensation can occur at a temperature much higher than the mass of the ...
