Thermophysical properties of fluorine are interesting because of its applications in different areas of technologyand industry. The computations of thermodynamic properties were performed with the GMA equation of stateunder critical conditions. The present work reports calculations of density, volumetric, and thermodynamicproperties of liquid fluorine on extended ranges of pressure and temperat...

4-Fluoropyrazole systems may be prepared by a single, sequential telescoped two-step continuous gas/liquid-liquid/liquid flow process from diketone, fluorine gas and hydrazine starting materials.

It is a great pleasure to be able to introduce this Themed series on organo-fluorine chemistry in the Beilstein Journal of Organic Chemistry. The introduction of fluorine into organic molecules is widely practiced particularly when tuning the properties of molecules for specialist functions. Of particular prominence is the role fluorine substitution finds in pharmaceutical development [1], and ...

Fluorine is the 13th most abundant element and, with other fluorine containing functional groups, is a most effective element in biological substances, pharmaceuticals, agrochemicals, liquid crystals, dyes, polymers and a wide range of consumer products. This reflects its resistance to metabolic change due to the strength of the C-F bond providing biological stability and the application of its...

Fluorine and carbon K absorption and emission spectra of liquid perfluorodecalin are presented and analyzed in terms of density functional calculations-configuration interaction. A comprehensive view of the electronic structure is given, and site-specific intramolecular interactions are investigated in detail. It is found that, while the outer fluorine atoms have excess charge in the ground sta...

A number of 1,4-bis(phenylethynyl)benzene derivatives (BPEBs) and their analogues with different numbers of side-substitute fluorine atoms on benzene rings, and alkyl chains, ethoxyl groups, fluorine atoms and trifluoromethyl groups as the end groups have been synthesized. The effects of the different substituents on their properties such as thermal behavior of melting point and clearing point,...

this research was conducted for the purpose of studying the effect of caf2 content in the composition of hotmetal pretreatment flux, based on lime. it was followed in regards to the importance of fluorine amount decrease in hot metal pretreatment and steel making processes. for this purpose, lime based fluxes including 40, 30, 20 and 10 percent calcium fluoride were prepared and hot metal pretr...

We developed room-temperature bonding of micro-nanofluidic device using fluorine induced plasma activation method. Fluorine was induced by O2 reactive ion etching (RIE) plasma treatment with Teflon Pieces which increased the bonding strength between fused silica glass substrates. The room-temperature bonded fused silica glass micro-nanofluidic device had high bonding strength as well as could w...
