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 ...

Properties of hydrogenated amorphous carbon films deposited by PECVD and modified by SF6 plasma
(Elsevier B.V. Sa, 2011-11-15)
Hydrogenated amorphous carbon (a-C:H) films were grown at room temperature on glass and polished silicon substrates using RF-PECVD (Radio-Frequency Plasma Enhanced Chemical Vapor Deposition). Plasmas composed by 30% of ...

Methane emission of cattle fed Urochloa brizantha hay harvested at different stages.
(Journal of Agricultural Science, Toronto, v. 8, n. 1 p. 163-174, 2016., 2016)
Morphological and Chemical Effects of Plasma Treatment with Oxygen (O-2) and Sulfur Hexafluoride (SF6) on Cellulose Surface
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2017-01-01)
Cellulose is a polymer widely available in nature, however its applications may be restrict due to its hydrophilic character. The creation of hierarchical structures on the surface is one of the required factors to obtain ...
Influence of supplemental dietary copper in high roughage rations on nutrient digestibility and methane emission in Holstein bulls
(Elsevier Science, 2021-02)
Feed additives, chemical inhibitors, and biological approaches have been studied and used to inhibit production of enteric methane (CH4) in ruminants by modifying methanogenic bacterial communities. However, information ...
Enteric methane emissions by lactating and dry cows in the high Andes of Peru
(Springer NetherlandsNL, 2022-03-26)
The objective of the study was to determine enteric methane emissions using the sulfur hexafluoride (SF6) technique and comparing with The Intergovernmental Panel on Climate Change (IPCC) methodology in lactating cows (LC) ...
