Fluoride intake of infants living in non-fluoridated and fluoridated areas [PDF]

open access: yesBritish Dental Journal, 2014
Data on fluoride exposure of infants are sparse. This study aimed to estimate total daily fluoride intake (TDFI) of infants aged 1-12 months, living in non-fluoridated and fluoridated areas in north-east England.Daily dietary fluoride intake was assessed using a three-day food diary coupled with analysis of fluoride content of food/drink consumed ...

Rh-Catalyzed Highly Enantioselective Synthesis of Aliphatic Sulfonyl Fluorides

open access: yesiScience, 2019
Summary: Rh-catalyzed, highly enantioselective (up to 99.8% ee) synthesis of aliphatic sulfonyl fluorides was accomplished. This protocol provides a portal to a class of novel 2-aryl substituted chiral sulfonyl fluorides, which are otherwise extremely ...

Deoxyfluorination of acyl fluorides to trifluoromethyl compounds by FLUOLEAD®/Olah’s reagent under solvent-free conditions

open access: yesBeilstein Journal of Organic Chemistry, 2020
A new protocol enabling the formation of trifluoromethyl compounds from acyl fluorides has been developed. The combination of FLUOLEAD® and Olah’s reagent in solvent-free conditions at 70 °C initiated the significant deoxyfluorination of the acyl ...

Layered Hybrid iron Fluorides

open access: yesCrystals, 2022
The first examples of layered hybrid iron fluorides are reported. In the reactions carried out, the chain compound (H2pipz)FeF5·H2O always occurs as the major phase, with the layered compounds, (H2pipz)3Fe4F18·2H2O and (H2pipz)2Fe3F13·H2O, being isolated

Determination of fluoride content in drinking water and tea infusions using fluoride ion selective electrode [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2007
Potentiometric analysis of fluoride content (as F- ion) in solutions by using fluoride ion-selective electrode is simple, reliable and cheap. Very small concentrations of fluoride-ions (to 10-6 mol/dm3) can be determined by fluoride selective electrode ...
