ESCA spectra of nitrogen oxides and oxygen have shown a splitting of core electron levels due to interaction between the emitted core electron and the unpaired valence electrons. No such effect is observed in the nitrogen molecule which is diamagnetic....
A valence鈥揺lectron theory is described in which core electrons are explicitly excluded, and in which their effects on valence electrons are incorporated ... Maurice,E.,Schwartz - 《Faraday Discussions of the Chemical Society》 被引量: 6发表: 1972年 Partial third-order quasiparticle theory: Comp...
A universal critical density underlying the physics of electrons at the LaAlO3/SrTiO3 interface The two-dimensional electron system formed at the interface between the insulating oxides LaAlO3 and SrTiO3 exhibits ferromagnetism, superconductivity, and... A Joshua,S Pecker,J Ruhman,... - 《Nature ...
Also reported are the core loss energies of 2s and 2p level electrons and the volume and surface plasmon losses of silicon. The chemical shifts occurring due to the bonding of silicon with oxygen and titanium are measured in the Auger and deep core level transitions. 展开 ...
Gas-phase oxygen 1s binding energy shifts, ..delta..E/sub B/(O 1s), in simple aliphatic alcohols were found to decrease in the order: water > methyl > ethyl > isopropyl > teri-butyl. Comparison with potential-model calculations showed that the shifts are attributable to relaxation in the...
The oxidized P680+ is then reduced by electrons stripped from water molecules through the function of OEC. In most phototrophs, the PSII core is usually associated with peripheral light-harvesting antennae, which are critical for increasing the light harvesting capability of the PSII core. In ...
Core-Excitation-Induced Bond Breaking of Chemisorbed Molecules Probed by Emission of Ions, Neutrals, and Electrons. CORE-EXCITATION-INDUCED BOND BREAKING OF CHEMISORBED MOLECULES PROBED BY EMISSION OF IONS, NEUTRALS, AND ELECTRONSFor selected examples of diatomic molecules ... Feulner,P.,Ecker,... ...
We attribute this feature to transfer ofs valence electrons away from the oxygen anions, thus creating empty states below the conduction band of the originally stoichiometric compound.doi:10.1080/01411599608242403Tafto, J.Bugge, R.Steinsvik, S....
These small shifts arise from the cancellation of two large initial-state effects, the electric field created by the ions at the surface and the consequent polarization of the metal conduction-band electrons. These two mechanisms induce rather large shifts of opposite sign and similar magnitude in ...
However, these biosensor types are less commonly used than the first-generation due to their low stability because of the immobilized mediators. The third-generation biosensors consist of the enzyme, redox polymer, and electrode. This biosensor can exchange electrons between the enzymes and the ...
