We have introduced an oxygen atom and a carbon-carbon double bond with a trans-configuration (E) into the terminal alkyl chain of a wide variety of liquid ... SM Kelley,A Germann,M Schadt - 《Liquid Crystals》 被引量: 51发表: 1994年 CO and NO adsorption and co-adsorption on the Pd...
Oxygen atom exchange between OH and (NO, ClO) has been investigated by ab initio molecular orbital methods. Reactants and transition states were fully optimized with second-order Mller–Plesset perturbation and coupled-cluster methods using the 6-311G(3df,3pd) basis set. Theoretical results pre...
The erosion yields of epoxy samples were from3.2×10−24cm3/atomto3.8×10−24cm3/atom.Surface bleaching by atomic oxygen was found in epoxy samples. The surface on silicone sample remained glossy after AO exposure. Both materials were analyzed using Scanning Electron Microscopy (SEM) and X‐...
Fig. 4.Schematic diagram of possible charge transfer recombination of electrons and holes[70]. 2.3.3Chemical reaction Chemical reactions can change the chemical state of the oxygen atom, which can lead to detachment of the oxygen atom from its normal position. For example, in some oxygen-contain...
First, we extract the wider environment of an atom with high uncertainty (indicated using a colourbar with red shading: note the “Large-scale simulation” is merely a schematic sketch). Then we keep the atom of interest, as well as the direct environment fixed, and we melt and anneal ...
A fraction of the interstellar neutral atoms crosses the interface between the solar wind and the ionized component of the local interstellar medium, and enters the heliosphere. The number of penetrating atoms depends on both the interface structure and the strength of the atom-plasma interaction, ...
The intensities of these low and high grey values contributions during the oscillations are shown in Fig. 4i. These intensities are proportional to the number of pixels of the respective grey levels of the image. Although the contributions of low grey and high grey values oscillated in phase, ...
The PBN spin adduct of the •H atom was also observed with cold atmospheric dry-helium40 and argon32 plasma. Figure 6 (a) PBN-H spectrum obtained after 150 s of plasma treatment in DMEM. (b) Effect of plasma exposure on PBN-H signal in three solvents. Half height of the middle ...
