The dendritic growth of lithium was suppressed on a lithium electrode surface modified by an ultrathin solid polymer electrolyte prepared from 1,1—difluoro-ethane by plasma polymerization [114]. 

Fluorinated Silicon Oxide. The introduction of fluorine in the ratio of 2 to 14 at.% lowers the dielectric constant, which is reported as low as 3.0. This is a major factor in the design of dielctric films. The CVD of these fluorinated compounds is accomplished by plasma-CVD and usually with Sip4 as a fluorine source. Also available are fluorinated compounds, such as fluorotriethoxysilane (FTES), l,2bis(methyldifluorosilyl)ethane, and 2,5disilahexane.P2]... 

Typical reaction products of NO removal in non-thermal plasma in the presence of propylene, predicted by the model in Martin et al. and Dorai and Kushner [86,88], include formaldehyde (HCHO), acetaldehyde (CH3CHO) methyl oxirane (C3H60), gly-coxal (CHO-CHO), methyl nitrite (CH3ONO), methyl nitrate (CH30N02), and 2-nitroso ethanal (ONCH2CHO). 

Microwaves have been used to generate plasma in methane at 5-50 Torr. The radicals produced in such a system were then allowed to react over a nickel catalyst, affording a mixture of ethane, ethene, and ethyne [74],...

Amifostine is hydrolyzed rapidly to 2-[(3-aminopropyl)amino]ethane-thiol (9.64) at the acidic pH of the stomach, and by alkaline phosphatases in various tissues. After intravenous administration to cancer patients, the plasma half-lives were found to be in the order of minutes. This is highly relevant, since most or all pharmacological effects of amifostine can be ascribed to its thiol metabolite. 

The preparation of film electrodes Prussian blue films are usually prepared by cycling an electrode in a freshly prepared solution containing iron(III) and hexacyanoferrate(III) ions [70-72]. As substrate, mostly platinum is used, sometimes glassy carbon [73] is used, and very frequently ITO electrodes [74] are used because the latter are very useful for electrochromism studies. Similar procedures using solutions containing metal ions and hexacyanoferrate(III) have been used to deposit cobalt hexacyanoferrate [75] and chromium hexacyanoferrate [76, 77]. Crumbliss et al. reported a plasma deposition of iron species from a plasma containing iron pentacarbonyl and ethane, followed by electrochemical derivatization of the deposited iron sites with the help of hexacyanoferrate solutions [78]. 

Effect of discharge frequency on the rate of ethane plasma polymerization [after Morita... 

Hydrogen, acetylene, and carbon monoxide are the primary products of the conversion of methane in the dc plasma system. In addition, small amounts of ethane, ethylene, and carbon dioxide are produced. Of the C2 products, acetylene accounts for 90%, while ethylene and ethane comprise 6% and 4%, respectively. Carbon dioxide is less than 0.2% of the effluent gas. No measurable amount of water is produced in the system. 

Another consideration concerns the profiles obtained for the different precursor gases. We expect the same radicals to be present in the plasmas of different gases. For example, C2H5 will certainly be produced in an ethane plasma by simple dissociation, but it will also be produced in a methane discharge due to various gas phase reactions. Therefore, it seems reasonable to model the profiles from all cavity positions and for all precursor gases with superpositions of one common set of single-/ profiles. The question that arises... 

LPCAT-CH4 treatment deposits plasma polymer of methane on the substrate surface. Since the energetic species are consumed in building up the layer of plasma polymer, the irradiation eflfects of plasma onto the exposed substrate polymer is much less. The excellent adhesion of a primer to the LPCAT-CH4-treated TPO was interpreted due to the replacement of the weak boundary layer by the interaction of tight network of plasma polymer of methane [23]. Plasma deposition from organic compounds, such as methane and ethane, can produce a thin layer of plasma polymer coating with tight networks.
