Non-equilibrium thermodynamics of gravitational screens [PDF]

open access: yes, 2014
We study the Einstein gravity equations projected on a timelike surface, which represents the time evolution of what we call a gravitational screen. We show that such a screen behaves like a viscous bubble with a surface tension and an internal energy ...

Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Hill's nano-thermodynamics is equivalent with Gibbs' thermodynamics for curved surfaces

open access: yes, 2018
We review first how properties of curved surfaces can be studied using Hill's thermodynamics, also called nano-thermodynamics. We proceed to show for the first time that Hill's analysis is equivalent to Gibbs for curved surfaces.

Ionic Liquid‐Based Reversible Metal Electrodeposition for Adaptive Radiative Thermoregulation Under Extreme Environments

open access: yesAdvanced Functional Materials, EarlyView.
A wideband tunable electrochromic device with dynamic thermal emissivity control is demonstrated. The system enables adaptive heat regulation via electrochemically modulated silver deposition, achieving efficient cooling and heating states. The flexible design ensures mechanical robustness under bending conditions, making it promising for portable and ...

Theories and heat pulse experiments of non-Fourier heat conduction

open access: yes, 2015
The experimental basis and theoretical background of non-Fourier heat conduction is shortly reviewed from the point of view of non-equilibrium thermodynamics. The performance of different theories is compared in case of heat pulse experiments.Comment: 12

A complete cosmic scenario from inflation to late time acceleration: Non-equilibrium thermodynamics in the context of particle creation [PDF]

open access: yes, 2014
The paper deals with the mechanism of particle creation in the framework of irreversible thermodynamics. The second order nonequilibrium thermodynamical prescription of Israel and Stewart has been presented with particle creation rate, treated as the ...

Harnessing Outer Space for Improved Electrocaloric Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

The non-equilibrium thermodynamics of active suspensions

open access: yesNew Journal of Physics
Active suspensions composed of self-propelled colloidal particles are considered. The propulsion of these micrometric particles is generated by chemical reactions occurring by heterogeneous catalysis at their surface and by diffusiophoresis coupling the ...
