Fluorine in the Solar neighborhood: No evidence for the neutrino process [PDF]
, 2016 Asymptotic Giant Branch stars are known to produce `cosmic' fluorine but it is uncertain whether these stars are the main producers of fluorine in the Solar neighborhood or if any of the other proposed formation sites, type II supernovae and/or Wolf-Rayet stars, are more important.

On the origin of fluorine in the Milky Way [PDF]
Mon.Not.Roy.Astron.Soc. 354 (2004) 575, 2004 The main astrophysical factories of fluorine (19F) are thought to be Type II supernovae, Wolf-Rayet stars, and the asymptotic giant branch (AGB) of intermediate mass stars. We present a model for the chemical evolution of fluorine in the Milky Way using a semi-analytic multi-zone chemical evolution model.

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Fluorination Effects on the Structural Stability and Electronic Properties of sp3 Type Silicon Nanotubes [PDF]
J. Phys. Chem. C 117, 14684-14691 (2013), 2013 A density functional theory study of the structural and electronic properties and relative stability of fluorinated sp3 silicon nanotubes and their corresponding silicon nanowires built along various crystallographic orientations is presented. The structural stability is found to increase linearly with the fluorine surface coverage and for coverages ...
