Experimental and numerical studies are performed to elucidate the fundamental chemical mechanisms by which CF3Br inhibits non-premixed hydrogen flames. These studies are motivated by previous work, which shows that CF3Br and its decomposition products inhibit hydrocarbon flames primarily by reacting ...
Because GC-MS test result reveals that no chemical change between C4F7N and activated alumina during the test, the adsorption effect is considered physical adsorption. The analysis shows that the CN group of C4F7N molecule has a weak interaction with activated alumina, which leads to its ...
The HFEs can react with OH radicals and possibly with Cl atoms in the atomosphere5–7, so that they have a reduced effect on global warming. The oxidation of HFEs initiated by OH radicals and Cl atoms can lead to the formation of hydrofluorinated esters (FESs). Then, the FESs' ...
The first excitation energy of N 2 is too high, which hinders its application as the buffer gas of CF 3 I. 展开 关键词: gas discharge CF3I gas mixtures Penning effect buffer gas DOI: 10.1088/2058-6272/aade83 年份: 2018 收藏 引用 批量引用 报错 分享 ...
and their genotype was confirmed by the amplification of the corresponding chloroplast DNA region by PCR (Supplementary Fig.1a). We also obtained ycf3-HA/Δycf3 double mutants by transforming the ycf3-HA mutant with the chloroplast vector in which theycf3gene has been disrupted by theaadAcas...
There is a similar effect for the auto suspension of the laptop on battery. It is obvious when the laptop will not exit suspension mode because the power indicator lights next to the power button and on the back of the laptop screen (...
Currently, lithium-ion batteries (LIBs) typically contain liquid electrolytes (LEs), which limit operation to ≤4.8 V [1]. LEs are organic liquids or gels the use of which present safety issues due to risks such as generation of volatile gaseous species, leakage, thermal runaway and flammabili...
the LSV also shows two electrons being transferred for wave 1 and 2 if one compares the LSV current to the one-electron redox process of an equimolar amount of the internal standard, decamethylferrocene (Fc*). The CV, LSV, and SWV results are therefore all mutually consistent with a one-...
The X-ray structure of 2a (M=Fe, R=Me) shows the formation of a pyrrole-like metallaring FeC(2)NC(4)C(5). The double bond character of the C(4) C(5) interaction [1.309(7)] suggests the enammine nature of the N(H)C(Me)C(CN) fragment which originates from conden...
X-ray crystallographic studies of a representative example, [IrCp*{(CF2)9CF3}(PMe3)2]+I-, shows the ground state structure of the cation in the solid to be of C1 symmetry, with the perfluoroalkyl ligand adopting a conformation in which the fluorines on each CF2 group reside in ...
