On Thermodynamic and Kinetic Mechanisms for Stabilizing Surface Solid Solutions
ACS Applied Materials & Interfaces, 2019 Many processes for energy storage rely on transformations between phases with strong separation tendencies. In these systems, performance limitations can arise from undesirable chemical and mechanical factors associated with the phase separation behavior. Solid solutions represent a desirable alternative, provided the conditions for their formation are

Learning Corrections for Hyperelastic Models From Data
Frontiers in Materials, 2019 Unveiling physical laws from data is seen as the ultimate sign of human intelligence. While there is a growing interest in this sense around the machine learning community, some recent works have attempted to simply substitute physical laws by data.

Electronic Structure and Phonon Thermodynamics of Iron Alloys [PDF]
, 2013 Inelastic neutron scattering (INS) and nuclear-resonant inelastic x-ray scattering (NRIXS) were used to measure phonon spectra of FeV as a B2- ordered compound and as a bcc solid solution.

Mechanical and thermodynamic properties of surfactant aggregates at the solid–liquid interface
Journal of Colloid and Interface Science, 2004 Surfactants are widely used to stabilize colloidal systems in a variety of industrial applications through the formation of self-assembled aggregates at the solid-liquid interface. Previous studies have reported that the control of surfactant-mediated slurry stability can be achieved through the manipulation of surfactant chain length and concentration.

Dependence of Heat Transport in Solids on Length-Scale, Pressure, and Temperature: Implications for Mechanisms and Thermodynamics [PDF]
Materials, 2021 Accurate laser-flash measurements of thermal diffusivity (D) of diverse bulk solids at moderate temperature (T), with thickness L of ~0.03 to 10 mm, reveal that D(T) = D∞(T)[1 − exp(−bL)]. When L is several mm, D∞(T) = FT−G + HT, where F is constant, G is ~1 or 0, and H (for insulators) is ~0.001. The attenuation parameter b = 6.19D∞−0.477 at 298 K for

Modelling of Dynamic Behaviour of Orthotropic Metals Including Damage and Failure [PDF]
, 2012 A physically based material model for metals, with elastic plastic and damage/failure orthotropy is proposed in this paper. The model is defined within the frameworks of irreversible thermodynamics and configurational continuum mechanics and integrated ...

Heat-exchange statistics in driven open quantum systems
New Journal of Physics, 2014 As the dimensions of physical systems approach the nanoscale, the laws of thermodynamics must be reconsidered due to the increased importance of fluctuations and quantum effects.

Incommensurate Crystallization of Neutron Matter in Neutron Stars
East European Journal of Physics, 2020 The composition of the neutron stars from its surface region, outer-core, inner-core, and to its center is still being investigated. One can only surmise on the properties of neutron stars from the spectroscopic data that may be available from time to ...
