Surface-dependent chemical properties of silicon nanowires: The acceleration of copper oxidation
TLDR
In this paper, the surface-dependent chemical properties of HF-treated silicon nanowires were investigated and shown to accelerate the oxidation rate of copper with an enhancement factor of 10,000, confirmed by x-ray diffraction semiquantitative analysis.Abstract:
HF-treated silicon nanowires exhibited surface-dependent chemical property and accelerated the oxidation rate of copper with the enhancement factor of 10 000, confirmed by x-ray diffraction semi-quantitative analysis. This unexpected oxidation characteristic would make HF-treated silicon nanowires valuable for catalysis applications.read more

Origin of Surface Conductivity in Diamond
TL;DR: Experimental evidence is given that hydrogen is only a necessary requirement for SC; exposure to air is also essential and a mechanism in which a redox reaction in an adsorbed water layer provides the electron sink for the subsurface hole accumulation layer is proposed.

Charge Transfer Equilibria Between Diamond and an Aqueous Oxygen Electrochemical Redox Couple
Vidhya Chakrapani,John C. Angus,Alfred B. Anderson,Scott D. Wolter,Brian R. Stoner,Gamini Sumanasekera +5 more
TL;DR: It is shown that electrons transfer between the diamond and an electrochemical reduction/oxidation couple involving oxygen is responsible for the surface conductivity and also influences contact angles and zeta potentials.
