An electronic structure description of atom and electron transfer in sulfite oxidasecrystal structurecomposite complexhydrogen bondingWe have shown that cymantrene derivatives are better P,N-chelate ligands for palladium-catalyzed allylic alkylation than ferrocenes, which have a similar pentagonal ligand ...
Subatomic particlenoun(physics) a very small piece of MATTER, such as an ELECTRON or a PROTON, that is smaller than an ATOM => compare ELEMENTARY PARTICLE Alpha particlenoun(physics) a PARTICLE with a positive electrical charge that is EMITTED (= sent out) by some RADIOACTIVE substance and ...
The atomic and electronic structure of stoichiometric and reduced ZnO wurtzite has been studied using a periodic relativistic all electron hybrid density functional (PBE0) approach and numeric atom-centered orbital basis set with quality equivalent to aug-cc-pVDZ. To assess the importance of relativisti...

The structure of atom consists of two parts: an atomic nucleus extra nucleus part The tiny atomic nucleus is the center of an atom. It constitutes positively charged particles “protons” and uncharged particles “neutrons.” On the other hand, the extra nucleus part is a much larger region....
When an electron is accelerated, it can absorb or radiate energy in the form of photons. Electrons, together with atomic nuclei made of protons and neutrons, make up atoms. However, electrons contribute less than 0.06% to an atom's total mass. The attractive Coulomb force between an electron...
Ionic amorphous oxide semiconductors (IAOSs) are new materials for flexible thin film transistors that exhibit field-effect mobilities of ～10 cm~2 V~(-1) s~(-1) [K. Nomura et al., Nature 488, 432 (2004)]. The local coordination structure in an IAOS, In-Ga-Zn-O (a-IGZO), was ...
(a) Write the ground-state electron configuration for an arsenic atom, showing the number of electrons in each subshell. (b) Give one permissible set of four quantum numbers for each of the outermost electrons in a single As atom when it is in its ground state. ...
apyrimidine ringand animidazolering. Although this is an oversimplified approach, it does provide, in theabsenceof experimental information, some insight as to the unpaired-electron distribution in purineπ-cations. First, we examine the structure of an imidazole cation. Two valence-bond representation...
Reduced nitrosyl polyoxomolybdates with the hitherto unknown decamolybdate Y structure: preparation and crystal and electronic structures of the two-electron reduced [Mo10O25(OMe)6(NO)], and the four-electron reduced [Mo10O24(OMe)7(NO)]2–. J. Am. Chem. Soc. 119, 3523–3535 (1997)....
