The presence of carbon–oxygen bonds on the surface of carbon nanotubes is associated with the formation of radiation defects. It is shown that an increase in the fraction of nitrogen atoms present in the substituting configuration in the N-MWCNTs wall structure due to the irradiation does not ...

The electronic structures and spectra of nitromethane and nitrogen dioxide have been calculated by a semiempirical method. The self‐consistent molecular o... McEwen,K Lenore - 《Journal of Chemical Physics》 被引量: 66发表: 1960年 Molecular electron affinities and the calculation of the temperature...
defining a doubled super cell using six of the available wyckoff positions. in these position, it is possible to set the 32 n and 32 sc atoms and can be used to make eight stoichiometric points in the sc–n compositional range. the results show significant trends. for low nitrogen ...

to enhance HER catalytic activities31. A synergistic strategy of doping nitrogen and intercalating PO43−is reported, which can convert 2H- to 1T-phase with a conversion rate of up to 41%, and has excellent HER performance32. However, the electronic transport capacity and phase stability of ...
We have also determined the pyroelectric response of the system by continuous oscillation method (AC method)44 from liquid nitrogen temperature to room temperature where the sample is subjected to thermal wave by a continuous, sinusoidally modulated laser of 0.1 Hz and the obtained data also ...
Reactions were performed in flame-dried glassware under an atmosphere of nitrogen. Non-aqueous solvents were degassed by sparging with nitrogen for 15 minutes prior to use and THF was passed through columns of activated alumina. Tetrakis(triphenylphosphine)palladium (Pd(PPh3)4) was obtained from Stre...
FIGURE 1. Stereo view of a DFT model of the Mn4O5Ca cluster in the S2 state and directly ligating amino acid residues and H2O/OH− molecules (18). Amino acids, except CP43-Glu-354, are from PS II subunit D1. Manganese, calcium, nitrogen, oxygen, carbon, and hydrogen atoms are ...
The accompanying BN bond indices of 1.487, 1.257, and 1.146 for CH2NBH2, (CH2N)2BH and (CH2N)3B, illustrate the decrease in multiple bonding due to the smaller dative π-bonding. In all three species there is a substantial σ-electron drift away from boron to nitrogen coupled with a ...
