Gallium and mercury are employed as liquid phases in a nanoporous carbonbased energy absorption system. Owing to the large surface tensions, the nanopore surface is non-wettable. Pressure-induced infiltration is observed and defiltration is difficult. The energy absorption efficiency is much higher than that of previously investigated nanoporous silica-based systems. The nominal solid–liquid in...

The energy release rate for propagation of a debond in either a single-fiber pull-out test or a microbond test was derived analytically. The key finding was that an accurate analysis can be derived by a global energy analysis that includes effects of residual stresses and interfacial friction but does not need to include the details of the stress state at the interfacial crack tip. The analytic...

This review explores the physics underlying the rheology of highly concentrated emulsions (HCEs) to determine the relationship between elasticity and HCE stability, and to consider whether it is possible to describe all physicochemical properties of HCEs on the basis of a unique physical approach. We define HCEs as emulsions with a volume fraction above the maximum closest packing fraction of m...

Homogeneous nucleation of the crystal phase in n-octane melts was studied by molecular simulation with a realistic, united-atom model for n-octane. The structure of the crystal phase and the melting point of n-octane were determined through molecular dynamics simulation and found to agree with experimental results. Molecular dynamics simulations were performed to observe the nucleation events a...

When the interfacial energy is a nonconvex function of orientation, the anisotropic curvature flow equation becomes backward parabolic. To overcome the instability thus generated, a regularization of the equation that governs the evolution of the interface is needed. In this paper we develop a regularized theory of curvature flow in threedimensions that incorporates surface diffusion and bulk-s...

abstract Perturbation theory, simulations and scaling arguments predict that there should be no static friction for two weakly interacting flat atomically smooth clean solid surfaces. The absence of static friction results from the fact that the atomic level interfacial potential energy is much weaker than the elastic potential energy, which prevents the atoms from sinking to their interfacial ...

The rapid development of ultrascaled III-V compound semiconductor devices urges the detailed investigation of metal-semiconductor contacts at nanoscale where crystal orientation, size, and structural phase play dominant roles in device performance. Here, we report the first study on the solid-state reaction between metal (Ni) and ternary III-V semiconductor (In0.53Ga0.47As) nanochannels to reve...

Interfaces are ubiquitous in nature. From solidification fronts to the surfaces of biological cells, interfacial properties determine the interactions between a solid and a liquid. Interfaces, specifically liquid-solid interfaces, play important roles in many fields of science. In the field of biology, interfaces are fundamental in determining cell-cell interactions, protein folding behavior an...

When the Gibbs-Thomson-Herring anisotropic capillary boundary condition is applied at the solidliquid interface of a crystallite with shape anisotropy, such as a needle crystal or dendrite, the interface can develop periodic non-monotone temperature distributions. This surprising result was discovered recently for the case of a slender ellipsoidal crystallite with its solid-melt interfacial ene...

S U M M A R Y The two-phase theory for compaction and damage proposed by Bercovici et al. (2001a, J. Geophys. Res.,106, 8887–8906) employs a nonequilibrium relation between interfacial surface energy, pressure and viscous deformation, thereby providing a model for damage (void generation and microcracking) and a continuum description of weakening, failure and shear localization. Here we examine...
