Controllable organization of a carboxylic acid type gemini surfactant at different pH values by adding copper(II) ions
Article Abstract:
The synthesis of the gemini surfactant sodium 4,8-dioctyl-3,9-dioxo-6-hydroxy-4,8-diaza-1,11-undecanedicarboxylate (SDUC) to characterize its surface activity and aggregation properties at different pH values is described. Remarkable transformations were observed within the SDUC aggregate structures when a small amount of [Cu.sup.2+] ion was added at pH 12.0 and 7.0.

Fabrication of highly antireflective silicon surfaces with superhydrophobicity
Article Abstract:
Chemical etching and fluoroalkysilane self-assembly are used as the means to fabricate highly antireflective porous silicon surfaces with superhydrophobicity. The morphology had enabled the porous silicon surface to own a very low reflectance value that is averaged to be about 3% over the whole experimental photon wavelength spanning 300-800 nm.

The influence of defects on the morphology of Si(111) etched in NH(sub 4)F
Article Abstract:
The effects of wafer miscut and water defects on the morphologies of Si (111) surface etched in NH(sub 4)F are studied by implementing a kinetic Monte Carlo (KMC) simulation. The defects result in persistent pit initiation, which leads to the formation of multilevel stacked pits.
