Boundary slip dependency on surface stiffness.
The paper investigates the effects of surface stiffness on the slip process aiming to obtain a better insight of the momentum transfer at nanoscale. The surface stiffness is modeled through the stiffness, κ, of spring potentials, which are employed to construct the thermal walls. It is shown that variations of stiffness, κ, influence the slip mechanism either toward slip or stick conditions. In...
متن کاملA Study on ZnO Nanorod Arrays Formed on the Surface of Polyester Fabric
A feasibility study on the possible growth of rod-shaped nano size zinc oxide particles on the surface of polyester fabric was investigated. The nanoparticles were produced using a hydrolysis method, with a zinc compound being utilized as the starter material. Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy/energy dispersive X-ray spectrometry (SEM/EDS) and X-ray d...
متن کاملSurface Roughness and Energy on Slip of Polymer Melts
Effect of surface topology and energy on slip velocity of high-density polyethylenes (HDPEs) was studied using treated and non-treated smooth and patterned slit dies. In order to examine the effect of surface roughness, laser ablation method was utilized to micro/nano-pattern the surface of dies. Moreover, effect of surface energy on slip was investigated by applying fluoroalkyl silane-based co...
متن کاملInfluence of surface hierarchy of superhydrophobic surfaces on liquid slip.
We investigated how the surface hierarchy of superhydrophobic (SHPo) surfaces influences liquid slip by testing well-defined microposts that have nanoposts only on their top. Contrary to the commonly held belief, our results show that such hierarchical surfaces do not always lead to an increase of slip length despite their reduced solid fraction and enhanced hydrophobicity compared to single-sc...
متن کاملEffect of Geometric Parameters of Superhydrophobic Surface on Liquid Slip
In this paper, we experimentally study how geometric parameters of textured hydrophobic surfaces affect a liquid slip, empowered by a custom-tuned microfabrication procedure that produces regular micro-patterns of posts and grates on an entire 4” wafer with a good size uniformity and no defect. A pitch of the patterns and a gas fraction of the structured surface are independently controlled, an...
