In this paper, pressure-driven gas flow through a microtube with constant wall temperature is considered. The ratio of the molecular mean free path and diameter cannot be negligible. Therefore, rarefaction taken into account. A solution obtained for subsonic as well slip continuum flow. Velocity, pressure, fields are analytically attained by macroscopic approach, using continuity, Navier-Stokes...
We study the magnetic-based motion control of a sperm-flagella driven Micro-Bio-Robot (MBR), and demonstrate precise point-to-point closed-loop motion control under the influence of the controlled magnetic field lines. This MBR consists of a bovine spermatozoon that is captured inside Ti/Fe nanomembranes. The nanomembranes are rolled-up into a 50 μm long microtube with a Islam S. M. Khalil and ...
Large arrays of multifunctional rolled-up semiconductors can be mass-produced with precisely controlled size and composition, making them of great technological interest for micro- and nano-scale device fabrication. The microtube behavior at different temperatures is a key factor towards further engineering their functionality, as well as for characterizing strain, defects, and temperature-depe...
The kinetics of ethylene (C2H4) and methane (CH4) on platinum (Pt) is investigated in an isothermal Pt microtube. A micro-kinetic model C1 C2 hydrocarbon oxidation the Pt(1 1 1) surface established using density functional theory tuned validated based experimental results obtained from Density (DFT) modelling carried out to evaluate coverage selected species thermochemistry kinetics. reasonably...
