Mechanical behavior of surface-patterned and coated Si or Ge wafers for superhydrophobic and antireflective light transmitting windows
نویسندگان
چکیده
The compressive resistance of truncated nanocone lattices produced by lithography and etching steps on Si or Ge wafers to get superhydrophobic antireflective light-transmitting windows, as well the protection efficiency alumina diamond coatings, is investigated numerical simulations elastic buckling, nanocompression tests. latter reveal limits an analysis, since stress at top cones high enough trigger plastic flow, phase changes. nano-cones exhibit a large ductility in compression even seem creep room temperature. Thin coatings are, however, shown provide effective against both buckling flow. Surface patterning induce concentrations foot cones, which reduces fracture substrate biaxial bending.

Drag reduction on a patterned superhydrophobic surface.
We present an experimental study of a low-Reynolds number shear flow between two surfaces, one of which has a regular grooved texture augmented with a superhydrophobic coating. The combination reduces the effective fluid-surface contact area, thereby appreciably decreasing the drag on the surface and effectively changing the macroscopic boundary condition on the surface from no slip to limited ...

In this article, we have performed calculations for studying the stability of the carbon group elements such as Si and Ge and also the magnetic elements like Fe and Co via first principle investigations. We found that Si and Ge decoupled from the interior surface of carbon nanotubes, this fact was independent in curvature, radius, conductivity and numbers of atoms in the carbon nanotubes. But t...

We present a facile approach for the fabrication of low-cost surface biomicrofluidic devices on superhydrophobic paper created by drop-casting a fluoroacrylic copolymer onto microtextured paper. Wettability patterning is performed with a common household printer, which produces regions of varying wettability by simply controlling the intensity of ink deposited over prespecified domains. The pro...
