We present the effect of surface attraction on the vapor-liquid equilibria of square well (SW) fluids in slit pores of varying slit width from quasi 3D to 2D regime using molecular simulation methodologies. Four to five distinct linear regimes are found for shift in the critical temperature with inverse slit width, which is more prominent at higher surface fluid interaction strength. On the oth...

BACKGROUND The effects of freezing-thawing cycles on intramedullary bone-implant interfaces have been studied in a rat model in mechanical pull-out tests. IMPLANTS: Twenty TiAl6V4 rods (Ø 0.8 mm, length 10 mm) implanted in rat tibiae METHODS 10 rats underwent bilateral tibial implantation of titanium rods. At eight weeks, the animals were sacrificed and tibiae harvested for biomechanical test...

The aim of the present study is to investigate the stability of crack propagation in cementitious materials. Tests were conducted on bend specimens in three-point and four-point loading conditions.Three-point bend specimens showed stable crack growth for mortar, normal strength and high strength concrete specimens. Alternatively, four-point bend specimens showed catastrophic failure for mortar ...

The interactions between a graphene sheet and an aluminium (111) layer in carbon-aluminium nanocomposite systems were investigated for various interfacial configurations using an ab initio simulation based on density functional theory. Dispersion relations and electron density distributions obtained for various interface registries suggest that the bond strength of the graphene/Al nanocomposite...

The effects of physisorbed polymer molecules on carbon nanotubes dispersed in a soft polymer matrix on the resulting mechanical strength of the nanocomposite are reported. From measurements of the large-strain deformation of the nanocomposites, the shear strength, τ, of the nanotube/matrix interface was determined as a function of the interfacial polymer chain length and the chain density, Σ. T...
