Chemical diffusion of fluorine in melts in the system Na2OAl2O3SiO2 [PDF]

open access: yes, 1985
The volatilization of fluorine from three melts in the system Na2OAl2O3SiO2 has been investigated at 1 atm pressure and 1200–1400°C. The melts chosen have base compositions corresponding to albite, jadeite and a peraluminous melt with 75 mole % SiO2 ...

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Fluorine chemistry at the millennium : fascinated by fluorine /

open access: yes, 2000
This volume brings together contributions by leading researchers covering a wide scope so characteristic of fluorine chemistry. It was in 1986 that the centennial of the isolation of fluorine by Moissan was celebrated, and much was said at the time about

Redox‐Active Guanidines

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Free radical reaction of fluorine containing compounds [PDF]

open access: yes, 1989
This thesis is concerned with the free-radical addition of oxygen containing compounds of the adducts produced. Free-radical additions of ether compounds to fluoroalkenes have been done by previous workers and the chemistry of some of these adducts has ...

Chemical diffusion of fluorine in jadeite melt at high pressure [PDF]

open access: yes, 1984
The chemical diffusion of fluorine in jadeite melt has been investigated from 10 to 15 kbars and 1200 to 1400°C using diffusion couples of Jadeite melt and fluorine-bearing jadeite melt (6.3 wt.% F). The diffusion profile data indicate that the diffusion

110GHz fT Silicon Bipolar Transistors Implemented using Fluorine Implantation for Boron Diffusion Suppression

open access: yes, 2006
This paper investigates how fluorine implantation can be used to suppress boron diffusion in the base of a double polysilicon silicon bipolar transistor and hence deliver a record fT of 110 GHz.
