quicksilverorhydrargyruma heavy silvery-white toxic liquid metallic element occurring principally in cinnabar: used in thermometers, barometers, mercury-vapour lamps, and dental amalgams. Symbol: Hg; atomic no: 80; atomic wt: 200.59; valency: 1 or 2; relative density: 13.546; melting pt: –...
As well as high gas temperature, a significantly higher relative ratio of N2+(B->X) emission intensity against N2 SPS and estimated high Tvib suggests the presence of high-density high energy electrons in SD. When discharge energies increase, the number, density and energy of electrons may al...
These relative weights computed from the chemical equation are sometimes called equation weights.Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance....
(see Supplementary Fig.2). The ratio between molecular and ionic species appears not to be much affected by pressure as the relative intensity of the respective IR bands do not change with pressure. Below 7.4 GPa, large modifications of the IR absorbance occur. Notably, all the spectral ...
As for Mg2+ and Ca2+ in the same valence state, due to the low relative molecular mass of Mg2+, the migration rate is higher at the same concentration level, which is consistent with the experimental results. The transmembrane process of cations is also an important part of their migration...
Next, the relationship between overall catalytic activity and K loading amount was investigated. When the loading amount of K promotor relative to Fe catalyst was increased up to 5.0 at%, ammonia yield increased (Supplementary Fig.3). However, a loading amount higher than 2.5 at% resulted in ...
Quadrupole mass spectrometry revealed that the concentrations of H 2 and N 2 measurably increased at pressures above 400 Torr. The primary reason for the increased roughness above 430 Torr was the enhanced etching of GaN via reaction with atomic and molecular hydrogen derived from the dissociation ...
relative to Cu1-N-C in NO2−(Fig.2b). The superior activity of Co3O4species toward NO2−electroreduction was further demonstrated by the higher Faradaic efficiency (FE) and yield rate for NH3of Co3O4/N-C in NO2−electroreduction relative to Cu1-N-C (Supplementary Fig.12). ...
(Fig.1band Supplementary Fig.1) show the small nanoparticles of RuIn3with an average size of ~6.1 nm deposited on the carbon black support. The atomic-resolution HAADF-STEM image reveals the highly ordered distribution of Ru and In atoms throughout the whole nanoparticle along the\([\bar...
