The Influence of Biofuels Addition on Shock-Induced Ignition and Combustion of Methane–Hydrogen Mixtures

open access: yesFire, 2023
The ignition and combustion of three-component methane–hydrogen biofuel mixtures, considered as prospective fuels, were experimentally and numerically studied. Ignition delays in argon-diluted methane–hydrogen mixtures partially substituted with methanol

Study of Soot Deposits during Continuous Methane Pyrolysis in a Corundum Tube

open access: yesApplied Sciences, 2023
Methane pyrolysis is one of the promising methods for producing low-carbon hydrogen, while one of the main problems of methane pyrolysis technology is soot clogging of the reactor space.

Two-dimensional Brownian motion of active particle on superfluid helium surface

open access: yesScientific Reports, 2023
We report an experimental study of the 2D dynamics of active particles driven by quantum vortices on the free surface of superfluid helium at T = 1.45 К. The particle motion at short times (

Intrinsic Brightness Temperatures of AGN Jets [PDF]

open access: yes, 2006
We present a new method for studying the intrinsic brightness temperatures of the parsec-scale jet cores of Active Galactic Nuclei (AGN). Our method uses observed superluminal motions and observed brightness temperatures for a large sample of AGN to ...

Dephasing at Low Temperatures

open access: yes, 1998
We discuss the significance and the calculation of dephasing at low temperatures. The particle is moving diffusively due to a static disorder configuration, while the interference between classical paths is suppressed due to the interaction with a ...

Sensing temperature [PDF]

open access: yesCurrent Biology, 2013
Temperature is an omnipresent physical variable reflecting the rotational, vibrational and translational motion of matter, what Richard Feynman called the "jiggling" of atoms. Temperature varies across space and time, and this variation has dramatic effects on the physiology of living cells.
