Thermoelectric energy converters under a trade-off figure of merit with broken time-reversal symmetry

open access: yes, 2017
We study the performance of a three-terminal thermoelectric device such as heat engine and refrigerator with broken time-reversal symmetry by applying the unified trade-off figure of merit ($\dot{\Omega}$ criterion) which accounts for both useful energy ...

Insight into Physical and Thermodynamic Properties of X3Ir (X = Ti, V, Cr, Nb and Mo) Compounds Influenced by Refractory Elements: A First-Principles Calculation

open access: yesCrystals, 2019
The effects of refractory metals on physical and thermodynamic properties of X3Ir (X = Ti, V, Cr, Nb and Mo) compounds were investigated using local density approximation (LDA) and generalized gradient approximation (GGA) methods within the first ...

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Global linear-irreversible principle for optimization in finite-time thermodynamics

open access: yes, 2018
There is intense effort into understanding the universal properties of finite-time models of thermal machines---at optimal performance---such as efficiency at maximum power, coefficient of performance at maximum cooling power, and other such criteria. In

Optimization of thermodynamic efficiency in binary-type geothermal electric power generating plants [PDF]

open access: yes, 1975
Calculations and curves are presented which prove that for each turbine entry temperature, there is an entry pressure which will optimize the thermodynamic efficiency of a ''binary'' type geothermal power plant. Comparisons are made between thermodynamic efficiency and another method of rating process efficiency.

Thermodynamic optimization on supercritical carbon dioxide Brayton cycles to achieve combined heat and power generation

open access: yesEnergy Conversion and Management, 2022
Abstract The development of combined heat and power (CHP) systems based on the supercritical carbon dioxide (SCO2) Brayton cycle is important to enhance the energy utilization efficiency and satisfy different energy demands. Therefore, this study summarizes and compares the SCO2 CHP configurations in terms of back-pressure heating (system without pre-
