Near-Field Thermal Transistor [PDF]

open access: yesPhysical Review Letters, 2014
Using a block of three separated solid elements, a thermal source and drain together with a gate made of an insulator-metal transition material exchanging near-field thermal radiation, we introduce a nanoscale analog of a field-effect transistor which is able to control the flow of heat exchanged by evanescent thermal photons between two bodies.

Perturbative nonequilibrium thermal field theory [PDF]

open access: yesPhysical Review D, 2013
We present a new perturbative formulation of non-equilibrium thermal field theory, based upon non-homogeneous free propagators and time-dependent vertices. Our approach to non-equilibrium dynamics yields time-dependent diagrammatic perturbation series that are free of pinch singularities, without the need to resort to quasi-particle approximation or ...

Coupled electro-thermal field in a high current electrolysis cell or liquid metal batteries [PDF]

open access: yesRoyal Society Open Science, 2018
Coupled electro-thermal field exists widely in chemical batteries and electrolysis industry. In this study, a three-dimensional numerical model, which is based on the finite-element software ANSYS, has been built to simulate the electro-thermal field in ...

Quantum Field Thermal Machines [PDF]

open access: yesPRX Quantum, 2021
Recent years have enjoyed an overwhelming interest in quantum thermodynamics, a field of research aimed at understanding thermodynamic tasks performed in the quantum regime. Further progress, however, seems to be obstructed by the lack of experimental implementations of thermal machines in which quantum effects play a decisive role.

Heat flow, Triassic rift system and Mesozoic-Cenozoic faults (south-east of Western Siberia) [PDF]

open access: yesНефтегазовая геология: Теория и практика, 2021
A qualitative and quantitative assessment of the influence of the Triassic rift system and Mesozoic-Cenozoic faults on the modern thermal field in the west of the Tomsk region has been carried out. It was revealed that the rift structures of the basement

Solar collectors network map: shape and time dynamics of stored thermal energy for different user loads [PDF]

open access: yesE3S Web of Conferences, 2020
Solar flat plate collectors are commonly used to transform solar energy into thermal one by heating a heat transfer fluid (HTF). The available thermal energy to the user is characterized by a certain thermal capacity and a certain temperature level ...

Phantom to control the thermal ablation process

open access: yesРоссийский технологический журнал, 2021
Medical equipment, due to its specificity, requires precise adjustment and testing. Therefore, before direct exposure to a human organism, the equipment is tested on specialized mock-ups of human  tissue – phantoms. The physicochemical characteristics of
