Spontaneity of nuclear fusion: a qualitative analysis via classical thermodynamics [version 3; peer review: 3 approved]

open access: yesOpen Research Europe, 2021
Background: So far the feasibility of nuclear reactions has been studied only through the evaluation of the reaction rate, which gives us information about the kinetics, while the thermodynamic analysis has been limited to evaluations of the change in ...

New insight into the melting process of PA 6 fibers: Determining tension-induced changes of enthalpy by HTA-assisted DSC analysis

open access: yesPolymer Testing, 2023
Differential scanning calorimetry (DSC) measurements of fibers are affected from insulation effects originating from the specific specimen geometry with poor contact between the material sample and the crucible bottom.

PREDICTION OF PHYSICOCHEMICAL PROPERTIES BY ARTIFICIAL NEURAL NETS

open access: yesAvances en Ciencias e Ingeniería, 2023
In this study, we employed the Artificial Neural Network-Group COSMO sigma profile method to estimate critical pressure, critical temperature, enthalpy of fusion, and melting temperature of pure chemical compounds.

A Computationally Efficient Multi-Scale Thermal Modelling Approach for PBF-LB/M Based on the Enthalpy Method

open access: yesMetals, 2022
Laser-Based Powder Bed Fusion is one of the most widely used additive manufacturing processes, mainly due to its high-quality output. End users would greatly benefit from a virtual simulation of the process; however, the modelling of the process is very ...

The solid-liquid interfacial free energy of close-packed metals: hard spheres and the Turnbull coefficient [PDF]

open access: yes, 2001
Largely due to its role in nucleation and crystal-growth, the free energy of the crystal-melt interfacial free energy is an object of considerable interest across a number of scientific disciplines, especially in the materials-, colloid- and atmospheric ...

A two-fluid helicity transport model for flux-rope merging

open access: yes, 2014
A two-fluid model for canonical helicity transport between merging flux-ropes is developed. Relative canonical helicity is defined here as the gauge invariant helicity of the canonical momentum of a given species, and represents the generalization of ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Comparison of predicted and experimental DSC curves for vegetable oils [PDF]

open access: yes, 2012
We compare experimental and predicted differential scanning calorimetry (DSC) curves for palm oil(PO), peanut oil (PeO) and grapeseed oil (GO). The predicted curves are computed from the solid–liquid equilibrium modelling and direct minimization of the ...
