cf4 Collection for sieyuan

The amount of adsorbed CF4 strongly depends on the pore size in nanotubes; at 1 bar the most efficient nanotubes for volumetric storage have size R = 0.68 nm. This size corresponds to the (10,10)

2016-2-11historical fluoride collection efficiency. When the collection fraction is greater than 90 percent, rooftop measurements of fugitive PFC emissions are difficult to make and the uncertainties are comparable with a good estimated value. • Based on recent measurement experience, some smelting process data requirements that

The paper reports on the reactive ion etching (RIE) and ion beam etching (IBE) of commercially available glasses and their usability for the fabrication of diffractive optical elements as an alternative for expensive quartz glass.

2018-9-1Perfluorocarbon greenhouse gases measured in Chinese rare earth metal production. • PFC gases included CF 4, C 2 F 6 and C 3 F 8 and trace levels of c-C 4 F 8, C 5 F 10.. CO 2-equivalent emission factors were estimated for three rare earth metals.. Emission intensities range from lower to similar levels vs. aluminium

A second option is a combination of three detectors: a RICH with CF4 gas both as a UV-photon radiator and as a gas amplification medium (a windowless approach); and a threshold Cherenkov detector

We present a combined experimental and theoretical investigation of the electron dynamics and body-frame angular dependence of valence photo-single ionization of CF4 and subsequent dissociation into CF3+ and F. Ionization from a valence t2 orbital shows overlapping shape resonances close to threshold that co
