There is a pressing need to shorten the development period for new materials possessing desired properties. For example, bulk metallic glasses (BMGs) are unique class of alloy utilized in wide variety applications due their attractive physical However, lack predictive tools uncovering relationships between BMGs' composition and properties limits further application these materials. In this study, machine-learning (ML) approach was developed, based on dataset 6471 alloys, enable construction...
The electrocaloric effect (ECE) of BaTiO3 multilayer thick film was investigated by direct calorimetric measurement. ECE increases monotonically with the enhancement applied field. maximum occurs above Tc and shifts to higher temperature increasing Under an ultrahigh field 800 kV/cm, it exhibits a giant ΔT = 7.1 K ΔS 10.1 J/kg · at 80 °C. heat follows general power-law relation varying rate within certain range. A high cooling power (∼50 W/kg) is achieved based on net-cooling resulting from...
Based on first principles calculations and self-consistent solution of the linearized Boltzmann–Peierls equation for phonon transport approach within a three-phonon scattering framework, we characterize lattice thermal conductivities k freestanding silicene, germanene stanene under different isotropic tensile strains temperatures. We find strong size dependence silicene with strain, i.e., divergent increasing system size; however, intrinsic room temperature unstrained converges to 19.34 W...
The electrocaloric (EC) effect of BaTiO3 multilayer thick film structure was investigated by direct measurement and theoretical calculation. samples were prepared the tape-casting method, which had 180 dielectric layers with an average thickness 1.4 μm. thermodynamic calculation based on polarization-temperature curves predicted a peak heat adsorption 0.32 J/g at 80 °C under 176 kV/cm electric field. via differential scanning calorimeter showed much higher EC 0.91 same difference could...
Abstract Pitting corrosion is one of the most destructive forms that can lead to catastrophic failure structures. This study presents a thermodynamically consistent phase field model for quantitative prediction pitting kinetics in metallic materials. An order parameter introduced represent local physical state metal within metal-electrolyte system. The free energy system described terms its ion concentration and parameter. Both transport electrolyte electrochemical reactions at...
Abstract Most metals naturally corrode in an engineering environment and form corrosion products. The products can be either soluble or insoluble the aqueous solution. (ICP) could have profound effects on kinetics of concerned metal. In this study, a multi-phase-field formulation is proposed to investigate ICP formation pitting kinetics. Gibbs free energy metal-electrolyte-insoluble product system consists chemical, gradient, electromigration energy. model validated with experimental results...
A Stone–Wales (SW) defect is a dipole of 5–7 ring pair in hexagonal network, which one the most important defective structures carbon nanotubes (CNTs) that will affect mechanical, chemical, and electronic properties CNTs. Using extended Hückel method, we calculated formation energy SW defects nanotubes. The was then fitted to simple formula as function tube radius orientation tube. This result provides convenient tool for study thermodynamics kinetics defects, well interaction with other types
Abstract We demonstrated a characterization method of entropy‐change measurement for the study electrocaloric effect (ECE). After specific heat capacity was measured under different applied fields using differential scanning calorimeter (DSC) accompanied with DC power supply, Δ S calculated from temperature integral capacities based on basic definition entropy. The S–T curve BaTiO 3 single crystal showed sharp peak around T c , which increased gradually and shifted to higher rise field. A...
