Alignments of a Microparticle Pair in a Glow Discharge

Molecules, 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

Molecules, 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,

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

Applied 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

On the saturation of excitation-dependent dipole-dipole broadening in dense Rb vapour [PDF]

E3S Web of Conferences
We study dependence of dipole-dipole interaction in dense Rb vapour on optical excitation. We measure the dipole-dipole contribution to the selective reflection spectrum of D2 line.

Experimental study of the nonreciprocal effective interactions between microparticles in an anisotropic plasma

Scientific Reports, 2020
There is a variety of cases in nature when the action–reaction symmetry is broken. In particular, suitable conditions for this are realized in colloidal suspensions and complex plasmas.

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

Plants, 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.

Multispectral High Temperature Thermography [PDF]

Sensors, 2022
The paper considers the issues of creating high-temperature digital thermographs based on RGB photodetector arrays. It has been shown that increasing the reliability of temperature measurement of bodies with unknown spectral coefficient of thermal radiation can be ensured by optimal selection of the used spectral range and registration of the observed ...
