Matrix-Assisted Processes in CH4-Doped Ar Ices Irradiated with an Electron Beam

open access: yesMethane, 2023
The relaxation processes induced by exposure of the Ar matrices doped with CH4 (0.1–10%) to an electron beam were studied with a focus on the dynamics of radiolysis products—H atoms, H2 molecules, CH radicals, and energy transfer processes.

Quantum mechanisms for selective detection in complex gas mixtures using conductive sensors

open access: yesScientific Reports, 2023
In this paper, we consider new quantum mechanisms for selective detection in complex gaseous media which provide the highest possible efficiency of quantum sensors and for the first time analyze their nature. On the basis of these quantum mechanisms, the

Detection of relativistic fermions in Weyl semimetal TaAs by magnetostriction measurements

open access: yesNature Communications, 2022
Detecting Weyl or Dirac charge carriers in topological semimetals is challenging due to the presence of their conventional counterparts. In this manuscript, the authors show that magnetostriction offers clearly distinguishable conventional and Weyl or ...

Majorana’s approach to nonadiabatic transitions validates the adiabatic-impulse approximation

open access: yesScientific Reports, 2023
The approach by Ettore Majorana for non-adiabatic transitions between two quasi-crossing levels is revisited and significantly extended. We rederive the transition probability, known as the Landau–Zener–Stückelberg–Majorana formula, and introduce ...

Thermoelectric current in a graphene Cooper pair splitter

open access: yesNature Communications, 2021
Thermoelectricity due to the interplay of the nonlocal Cooper pair splitting and the elastic co-tunneling in normal metal-superconductor-normal metal structure is predicted.

Modelling of a low-temperature differential Stirling engine [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2007
A full theoretical model of a low-temperature differential Stirling engine is developed in the current paper. The model, which starts from the first principles, gives a full differential description of the major components of the engine: the behaviour of the gas in the expansion and the compression spaces; the behaviour of the gas in the regenerator ...

Generation and Diagnostics of Ambient Air Glow Discharge in Centimeter-Order Gaps

open access: yesIEEE Access, 2020
Re-pulsing glow discharges in gaps up to 2 cm were experimentally investigated in atmospheric pressure air. Discharge was ignited as a sequence of spark and glow discharge and sustained in a glow regime after ignition. It was confirmed that the discharge

Laboratory photochemical processing of aqueous aerosols: formation and degradation of dicarboxylic acids, oxocarboxylic acids and α-dicarbonyls [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
To better understand the photochemical processing of dicarboxylic acids and related polar compounds, we conducted batch UV irradiation experiments on two types of aerosol samples collected from India, which represent anthropogenic (AA) and biogenic (BA ...
