Thermal transport enhancement of hybrid nanocomposites; impact of confined water inside nanoporous silicon

, 2020
The thermal transport properties of porous silicon and nano-hybrid "porous silicon/water" systems are presented here. The thermal conductivity was evaluated with equilibrium molecular dynamics technique for porous systems made of spherical voids or water-

Effect of Electron-Phonon Coupling on Thermal Transport across Metal-Nonmetal Interface - A Second Look

, 2015
The effect of electron-phonon (e-ph) coupling on thermal transport across metal-nonmetal interfaces is yet to be completely understood. In this paper, we use a series of molecular dynamics (MD) simulations with e-ph coupling effect included by Langevin ...

Thermal Effect in Nonlinear One-Dimensional Consolidation of Cold Region Soil

Energies, 2022
The thermal effect can significantly influence the consolidation of the soil, especially in the cold region. Previous studies have established to research that the drops in the ambient temperature would slow down the consolidation process, resulting in ...

Thermal contraction in silicon nanowires at low temperatures

, 2010
The thermal expansion effect of silicon nanowires (SiNW) in [100], [110] and [111] directions with different sizes is theoretically investigated. At low temperatures, all SiNW studied exhibit thermal contraction effect due to the lowest energy of the ...

The effect of undrained heating on a fluid-saturated hardened cement paste [PDF]

, 2008
The effect of undrained heating on volume change and induced pore pressure increase is an important point to properly understand the behaviour and evaluate the integrity of an oil well cement sheath submitted to rapid temperature changes.

A simple modelling on transmission torque of eddy‐current axial magnetic couplings considering thermal effect

IET Electric Power Applications, 2022
This paper proposes modelling on the transmission torque of an eddy‐current axial magnetic coupling (EAMC) considering the thermal effect. A new and simple equivalent reluctance network is established to obtain the magnetic flux density based on the two ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
