Effect of finite volume on thermodynamics of quark-hadron matter

open access: yesPhysical Review D
The effects of a finite system volume on thermodynamic quantities, such as the pressure, energy density, specific heat, speed of sound, conserved charge susceptibilities, and correlations, in hot and dense strongly interacting matter are studied within the parity-doublet chiral mean field model.

Separability of specific volume in thermodynamic equation of state

open access: yesChinese Physics, 2001
A type of system, in which the specific volume can be divided into several parts according to its Hamiltonian, has been obtained in a grand ensemble. The main character of such a system is that its Hamiltonian is absolutely separable. We also discuss the partial specific volume contributed by thermoelectrons in metals under a free-interaction ...

Electrically Induced Negative Differential Resistance States Mediated by Oxygen Octahedra Coupling in Manganites for Neuronal Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
The negative differential resistance is exploited, using a La0.67Sr0.33MnO3 thin film network to demonstrate various neuronal functionalities of the human brain, such as leaky‐integrate‐fire and oscillatory patterns. Transmission electron microscope studies show local modification in oxygen octahedra in the network leads to co‐existing phases ...

The Constant Volume Gas Turbine: A Thermodynamic Assessment [PDF]

open access: yesVolume 1B: General, 1974
A quasi-steady-state analysis is made of the performance of a gas-turbine working with intermittent, constant volume combustion. Variables considered include inlet temperature, compressor pressure ratio, scavenge ratio, combustion time, heat exchanger thermal ratio. Characteristics are computed over a full loading range.

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 ...

Off‐Stoichiometry Engineering of the Electrical and Optical Properties of SrNbO3 Using Oxide Molecular Beam Epitaxy

open access: yesAdvanced Functional Materials, EarlyView.
The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...
