Typical Periods for Two-Stage Synthesis by Time-Series Aggregation with Bounded Error in Objective Function

open access: yesFrontiers in Energy Research, 2018
Two-stage synthesis problems simultaneously consider here-and-now decisions (e.g., optimal investment) and wait-and-see decisions (e.g., optimal operation). The optimal synthesis of energy systems reveals such a two-stage character.

Thermodynamics of the FRW universe at the event horizon in Palatini f(R) gravity

open access: yes, 2018
In an accelerated expanding universe, one can expect the existence of an event horizon. It may be interesting to study the thermodynamics of the Friedmann-Robertson-Walker (FRW) universe at the event horizon.

Thermodynamics of Lemaitre-Tolman-Bondi Model

open access: yes, 2010
Here we consider our universe as inhomogeneous spherically symmetric Lemaitre-Tolman-Bondi Model and analyze the thermodynamics of this model of the universe. The trapping horizon is calculated and is found to coincide with the apparent horizon.

Introduction to Quantum Thermodynamics: History and Prospects

open access: yes, 2018
Quantum Thermodynamics is a continuous dialogue between two independent theories: Thermodynamics and Quantum Mechanics. Whenever the two theories addressed the same phenomena new insight has emerged.

Black Hole Thermodynamics and Two-Dimensional Dilaton Gravity Theory [PDF]

open access: yes, 1999
We relate various black hole solutions in the near-horizon region to black hole solutions in two-dimensional dilaton gravity theories in order to argue that thermodynamics of black holes in D>=4 can be effectively described by thermodynamics of black ...

Diffusion in multicomponent aqueous alcoholic mixtures

open access: yesScientific Reports, 2021
The Fick diffusion coefficient matrix of the highly associating quaternary mixture water + methanol + ethanol + 2-propanol as well as its ternary and binary subsystems is analyzed with molecular dynamics simulation techniques.

Demonstration of the stabilization of solar salt at 620 C with a semi-closed configuration in a 100 kg-scale

open access: yesHeliyon, 2023
Among the variety of energy storage techniques thermal energy storage (TES), based on molten salts, is already in use for the storage of heat in a gigawatt hour scale.

Unitary Thermodynamics from Thermodynamic Geometry [PDF]

open access: yesJournal of Low Temperature Physics, 2013
Degenerate Fermi gases of atoms near a Feshbach resonance show universal thermodynamic properties, which are here calculated with the geometry of thermodynamics, and the thermodynamic curvature $R$. Unitary thermodynamics is expressed as the solution to a pair of ordinary differential equations, a "superfluid" one valid for small entropy per atom $z ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Thermocapillary central lamella recess during droplet impacts onto a heated wall

open access: yesScientific Reports
We experimentally observe a new phenomenon, the formation of a toroidal region of lower film thickness in the center of the lamella formed during high Weber number water droplet impacts onto smooth heated walls.
