Phase transformations in nanograin materials under high pressure and plastic shear: nanoscale mechanisms.
There are two main challenges in the discovery of new high pressure phases (HPPs) and transforming this discovery into technologies: finding conditions to synthesize new HPPs and finding ways to reduce the phase transformation (PT) pressure to an economically reasonable level. Based on the results of pressure-shear experiments in the rotational diamond anvil cell (RDAC), superposition of plasti...
متن کاملHigh-pressure mechanochemistry: Conceptual multiscale theory and interpretation of experiments
Fifteen mechanochemical phenomena observed under compression and plastic shear of materials in a rotational diamond anvil cell (RDAC) are systematized. They are related to strain-induced structural changes (SCs) under high pressure, including phase transformations (PTs) and chemical reactions. A simple, three-scale continuum thermodynamic theory and closed-form solutions are developed which exp...
متن کاملPhase-field modeling of nanoscale island dynamics
We present a phase-field model to simulate the dynamics of a perturbed circular island during epitaxial growth. Surface diffusion and a far-field flux are incorporated in the model. Moreover, a modified free energy function together with a correction to the initial phase variable profile is given to efficiently capture the morphological evolution when a large deposition flux is imposed. To test...
متن کاملNumerical Study of Single Phase/Two-Phase Models for Nanofluid Forced Convection and Pressure Drop in a Turbulence Pipe Flow
In this paper, the problem of turbulent forced convection flow of water- alumina nanofluid in a uniformly heated pipe has been thoroughly investigated. In numerical study, single and two-phase models have been used. In single-phase modeling of nanofluid, thermal and flow properties of nanofluid have been considered to be dependent on temperature and volume fraction. Effects of volume fraction a...
متن کاملEffects of the Spacer Length on the High-Frequency Nanoscale Field Effect Diode performance
The performance of nanoscale Field Effect Diodes as a function of the spacer length between two gates is investigated. Our numerical results show that the Ion/Ioff ratio which is a significant parameter in digital application can be varied from 101 to 104 for S-FED as the spacer length between two gates increases whereas this ratio is approximately constant for M-FED. The high-frequency perform...
