Growth of Patterned Surfaces

Cell Growth on Zein Surfaces Self-Assembled on Patterned Templates

Zein is the alcohol soluble protein of corn. Its secondary structure was investigated by circular dichroism and by X-ray scattering measurements. Both studies considered that the spatial-structure model for zein contains nine successive helical segments folded upon each other in an anti-parallel fashion, linked at each end by glutamine-rich turns or loops and stabilized by hydrogen bonds. The g...

Directional Wetting on Patterned Surfaces

Spreading of Large Drops on Patterned Surfaces

Spreading of Large Drops on Patterned Surfaces — We report an experimental study of the shape of large liquid drops spreading on surfaces with patterns of wettability. The patterns are sets of disks of a material less wettable than the rest of the plane substrate. When few defects are present, or when the average distance between defects is large compared to the capillary length, the drop edge ...

Computer Simulation of Nucleation on Patterned Surfaces

We have studied qualitatively the effect of patterned substrate surface on adatom nucleation using Kinetic Monte Carlo simulations and solid-on-solid model. The inhomogeneity in the activation energies of adatom diffusion was incorporated into the simulations using two models: a) periodic variation of the adatom–substrate interaction energy as a function of the adatom lateral position and b) ad...

Wetting study of patterned surfaces for superhydrophobicity.

Superhydrophobic surfaces have considerable technological potential for various applications due to their extreme water-repellent properties. A number of studies have been carried out to produce artificial biomimetic roughness-induced hydrophobic surfaces. In general, both homogeneous and composite interfaces are possible on the produced surface. Silicon surfaces patterned with pillars of two d...
