Understanding Organic Film Behavior on Alloy and Metal Oxides
TLDR
Interestingly, on the alloy surfaces, the presence of less reactive metal sites does not inhibit film formation and the effect of the acidity of the organic moiety and substrate composition on the film characteristics and stability is discussed.Abstract:
Native oxide surfaces of stainless steel 316L and Nitinol alloys and their constituent metal oxides, namely nickel, chromium, molybdenum, manganese, iron, and titanium, were modified with long chain organic acids to better understand organic film formation The adhesion and stability of films of octadecylphosphonic acid, octadecylhydroxamic acid, octadecylcarboxylic acid, and octadecylsulfonic acid on these substrates were examined in this study The films formed on these surfaces were analyzed by diffuse reflectance infrared Fourier transform spectroscopy, contact angle goniometry, atomic force microscopy, and matrix-assisted laser desorption ionization mass spectrometry The effect of the acidity of the organic moiety and substrate composition on the film characteristics and stability is discussed Interestingly, on the alloy surfaces, the presence of less reactive metal sites does not inhibit film formationread more

Wet chemical surface functionalization of oxide-free silicon
TL;DR: In this paper, the main preparation methods of oxide-free H-terminated Si surfaces and their stability are summarized, and functionalization is classified into indirect substitution of Htermination by functional organic molecules, such as hydrosilylation, and direct substitution by other atoms (e.g. halogens) or small functional groups (i.e. OH, NH 2 ) that can be used for further reaction.

TL;DR: It is demonstrated that hydroxyl groups on oxide-free silicon are more reactive than on silicon oxide, and suggested new directions to functionalize silicon for sensors, photovoltaic devices, and nanoelectronics are suggested.
