Probabilistic thermodynamic analysis of metabolic networks [PDF]

open access: yesBioinformatics, 2020
Abstract Motivation Random sampling of metabolic fluxes can provide a comprehensive description of the capabilities of a metabolic network. However, current sampling approaches do not model thermodynamics explicitly, leading to inaccurate predictions of an organism’s potential or actual ...

A Simple Thermodynamic Analysis of Photosynthesis [PDF]

open access: yesEntropy, 2007
In this paper we present a comparative study of nine photosynthetic pathways bymeans of their thermodynamic performance. The comparison is made by using the thermalefficiency of light-to-chemical energy conversion and the so-called ecological criterionarising from finite-time thermodynamics.

Comparative Analysis of Isochoric and Isobaric Adiabatic Compressed Air Energy Storage

open access: yesEnergies, 2023
Adiabatic Compressed Air Energy Storage (ACAES) is regarded as a promising, grid scale, medium-to-long duration energy storage technology. In ACAES, the air storage may be isochoric (constant volume) or isobaric (constant pressure).

Theoretical Study of a Novel CO2 Supersonic Two-phase Expansion Refrigeration Cycle

open access: yesZhileng xuebao, 2021
Natural refrigerants such as CO2 have become a research hotspot. Under high-pressure conditions, a large throttling loss becomes the primary reason for the low circulation efficiency of the CO2 refrigeration cycle. Therefore, reducing the throttling loss
