Nano-porous silicon were simply prepared from p-type single crystalline silicon wafer by electrochemical etching technique via exerting constant current density in two different HF-Ethanol and HF-Ethanol-H2O solutions. The mesoporous silicon layers were characterized by field emission scanning electron microscopy and scanning electron microscopy. The results demonstrate that the width of nano-p...
We have studied adsorption in regular, self-ordered alumina pores open at both ends or only at one end. The straight, non-connected pores have diameters ranging from 22 to 83 nm, with a relative dispersion below 1% in the pore size. Adsorption isotherms measured in open pores with a torsional microbalance show pronounced hysteresis loops characterized by nearly vertical and parallel adsorption ...
We report on the assembly of gold nanoparticle (AuNPs) superlattices at liquid/vapor interface and in bulk their suspensions. Interparticle distances assemblies are achieved multiple length scales by varying chain lengths surface grafted AuNPs polyethylene glycol (PEG) with molecular weights range 2000–40,000 Da. Crystal structures lattice constants both 2D 3D determined synchrotron-based surfa...
