442. The effect of complex-formation by phosphine oxides on their P–O stretching frequencies
TLDR
In this article, the ingrared spectra of trimethyl- and triphenylphosphine oxide and a number of their complexes with various transition-metal cations were examined, and an explanation in terms of a lowering of the P-O bond order was proposed.Abstract:
S>The ingrared spectra of trimethyl- and triphenylphosphine oxide and a number of their complexes with various transition-metal cations were examined. Complexformation causes the P-O stretching frequencies to shift approximately 50 cm/sup -1/ to lower values. Since a simple linematic effect would raise the frequency, an explanation in terms of a lowering of the P-O bond order is proposed. (auth)read more

TL;DR: The rational synthesis of phase pure, highly crystalline cubic FeS(2) nanocrystals (NCs) using a trioctylphosphine oxide (TOPO) assisted hot-injection method indicates that TOPO passivates both iron and sulfur atoms on FeS (2) NC surfaces, efficiently inhibiting surface decomposition.

The inhibition of graphite oxidation by phosphorus additives
TL;DR: In this article, it was found that graphite with organic phosphate and phosphite esters has an increased resistance to air oxidation at elevated temperatures, and that a hydrophilic residue strongly adsorbed on the graphite surface at active sites where oxidation normally occurs.
