At present,reports on the arc interruption and decomposition behavior of a C_(4)F_(7)N/air gas mixture especially the biosafety of its by-products are ***,a 57%C_(4)F_(7)N/43%air gas mixture was employed as an arc-quenching medium to conduct 200 breaking tests on a load switch(630 A/24 kV).The arc interruption and decomposition behavior of the gas mixture were evaluated,and the biosafety of the decomposition products was assessed based on an acute inhalation toxicity *** was found that the average arcing time of the 200 breakings was about 10.1 ms and that breakings were basically completed at the zero-crossing of the second or third current *** gas mixture after breaking decomposed dramatically(the C_(4)F_(7)N content decreased by 75.6%),generating a large number of gaseous by-products(CO,CF_(4),C_(2)F_(6),C_(3)F_(8),CF_(3)CN,C_(4)F_(8),CO_(2),C_(4)F_(10)N_(2),C_(3)F_(6),C_(2)N_(2),etc.)as well as solid by-products(carbon particles).The lethal concentration of 50%(LC50,4 h)of C_(4)F_(7)N/air after 200 breakings was 31 ppm(male mice)and 34 ppm(female mice),respectively,and the toxicity was classified as Grade *** general,C_(4)F_(7)N has an arc interruption capability,albeit weaker than that of SF_(6)under the same *** breaking,the C_(4)F_(7)N gas mixture has a relatively high acute inhalation toxicity,and relevant safety protection measures for research or operation personnel are strictly needed.

In order to acquire a broadband absorption spectrum in a single shot,a compact radiation source was developed by using a Z-pinch type electric *** paper presents the mechanical and electrical construction of the source,as well as its electrical and optical characteristics,including the intense continuum of radiation emitted by the source in the UV and visible spectral *** also shows that the compactness of the source allows direct coupling with the probed medium,enabling broadband absorption measurement in the spectral range of 200e300 nm without use of an optical fiber which strongly attenuates the light in the short wavelength ***,thanks to this source,broadband spectral absorption of NO molecules around 210 nm and that of OH molecules around 310 nm were recorded in this direct coupling *** atom spectral absorption around 325 nm of the peripheral cold zones of an intense transient arc was also recorded.

Molecular dynamics simulations of initial Pd and PdO nanocluster growth in a magnetron gas aggregation source

引用

Frontiers of Chemical Science and Engineering 2019年第2期13卷 324-329页

作者： Pascal Brault William Chamorro-Coral Sotheara Chuon Amael Caillard jean-marc bauchire Stevè Baranton Christophe Coutanceau Erik Neyts GREMI UMR 7344 CNRS Universite d'Orleans45067 Orleans Cedex 2France IC2MP UMR 7285 CNRS Universite de Poitiers86073 Poitiers Cedex 9France Department of Chemistry University of Antwerp2610 AntwerpBelgium

Molecular dynamics simulations are carried out for describing growth of Pd and PdO nanoclusters using the ReaxFF force field. The resulting nanocluster structures are successfully compared to those of nanoclusters experimentally grown in a gas aggregation source. The PdO structure is quasi-crystalline as revealed by high resolution transmission microscope analysis for experimental PdO nanoclusters. The role of the nanocluster temperature in the molecular dynamics simulated growth is highlighted.
