Graphene to fluorographene and fluorographane: A theoretical study
(2013-01-25)
We report here a fully reactive molecular dynamics study on the structural and dynamical aspects of the fluorination of graphene membranes (fluorographene). Our results show that fluorination tends to produce defective ...
The reverse fluorine Perlin-like effect and related stereoelectronic interactions
(American Chemical Society (ACS), 2020)
Effects of helium ion irradiation on fluorinated plasma polymers
(Elsevier B.V. Sa, 2010-06-25)
The effects of ion irradiation on fluorinated plasma polymer films are investigated using profilometry, surface contact-angle measurements, infrared reflection absorption spectroscopy (IRRAS) and X-ray photoelectron ...
Radionuclides, heavy metals and fluorine incidence at Tapira phosphate rocks, Brazil, and their industrial (by) products
(Elsevier B.V., 2006-01-01)
Inorganic phosphate fertilizers may contain radionuclides, heavy metals and fluorine. This paper presents the possible environmental hazards from Tapira phosphate rocks and their (by) products (Brazil) utilized as phosphate ...
Fluorinated polymer films from r.f. plasmas containing benzene and sulfur hexafluorine
(1992-11-20)
Mixtures of C6H6 and SF6 were polymerized in an r.f. discharge. Actinometry (quantitative optical emission spectroscopy) was used to determine trends in the plasma concentrations of the species F, H and CH as a function ...
Study of fluorine losses in oxyfluoride glasses
(Elsevier B.V., 2005-12-15)
Glasses in PbGeO3-PbF-CdF2 and GeO2-PbO-PbF2-CdF2 systems were studied and the fluorine losses during synthesis were investigated. Samples were characterized by differential scanning calorimetry (DSC), X-ray diffraction, ...
Effect of the fluorination of DLC film on the corrosion protection of aluminum alloy (AA 5052)
(Elsevier B.V. Sa, 2010-06-25)
It is presented a study conducted on the physical and electrochemical properties of fluorinated a-C:H films deposited onto a commercial aluminum alloy (AA 5052). The coatings were deposited from mixtures of 91% of acetylene ...
Efeito dose-resposta de uma formulação de dentifrício com concentração reduzida de fluoreto - estudo in vitro.
(2002-10-01)
The utilization of dentifrices with low fluorine concentration, for children under 6 years of age, has been suggested to reduce the risks of dental fluorosis. However, in order to have anticariogenic potential, the dentifrice ...
FLUORINATED POLYMER-FILMS FROM RF PLASMAS CONTAINING BENZENE AND SULFUR HEXAFLUORINE
(Elsevier B.V., 1992-11-20)
Mixtures of C6H6 and SF6 were polymerized in an r.f. discharge. Actinometry (quantitative optical emission spectroscopy) was used to determine trends in the plasma concentrations of the species F, H and CH as a function ...
