Origin of temperature dependent conductivity of $α$-polyvinylidene fluoride [PDF]
J. Chem. Phys. 122, 084901 (2005), 2004 The conductivity of $\alpha$-polyvinylidene fluoride ($\alpha$-PVDF) is obtained from dielectric measurements performed in the frequency domain at several temperatures. At temperatures above the glass-transition, the conductivity can be interpreted as an ionic conductivity, which confirms earlier results reported in the literature.

Luminescence of photochromic centers in calcium fluoride crystals doped with Lu$^{3+}$ ions [PDF]
, 2015 We report data on the luminescence spectra associated with photochromic centers in X-ray irradiated calcium fluoride crystals doped with Lu ions. Irradiation in low energy photochromic centers absorption band excites emission, which can be identify with transitions into photochromic centers.

Chemical Adsorption of HF, HCl, and H2O onto YF3 and Isostructural HoF3 Surfaces by First Principles
Crystals, 2023 The two elements, yttrium and holmium, form a geochemical twin pair as their cations possess equivalent ratios of charge to radius. However, despite their equal electrostatics, a subtle difference in their fluoride or chloride affinity is known within ...

Effects of air pollutants on lemons and navel oranges
California Agriculture, 1968 Air Pollutants, especially photo- chemical smog and fluorides, are known to cause major damage to agricultural crops. Commercial production of leafy vegetables has been seriously hampered in the Los Angeles Basin because of oxidant lesions which reduce ...

Migration of fluoride ions from the permanent teeth into saliva in children with glass ionomer cement restorations: An in vitro study [PDF]
Vojnosanitetski Pregled, 2013 Bacground/Aim. Glass ionomer cements (GIC) belong to the group of polycarboxyl cements, and one of the principal characteristics of these materials is their anticariogenic potential of fluorine release into saliva and enamel-dentin substance.
