The excited-state hydrogen atom transfer of a phenol-(ammonia)5 hexamer is like a race. In their Communication on page 15089 ff. C. Jouvet, M. Fujii et al. show by time-resolved spectroscopy that an electron jumps like a hare, reaching the solvent "princess" within 3 ...
The theoretical absorption spectrum is compared with electron energy loss spectroscopy (EELS) performed on a single crystal. Here we succeed in using EELS at high-energy resolution as a stand-alone technique for measuring the band gap as well as obtaining the dielectric function of BaSnO3. An ad...
Transmission of interacting electrons through a one-dimensional periodic potential Electron transport through a periodic potential in the presence of a short-range repulsive interaction is investigated in the mean-field approximation. The... Y Takagaki,Y Tokura,S Tarucha - 《Phys.rev.b》 被引量: ...
I am curious about how a superfluid might behave in a vacuum under conditions of zero gravity. Byanon15944— On Jul 25, 2008 Under normal pressure, helium never freezes. It only freezes at higher pressures. The reason it doesn't freeze is due to helium's high zero-point energy (a quant...
Relativistic effects in electron-energy-loss-spectroscopy observations of the ${mathrm{S}mathrm{i}/mathrm{S}mathrm{i}mathrm{O}}_{2}$ interface plasmon peak Electron-energy-loss spectroscopy in a scanning transmission electron microscope has been used to study the interface plasmon peak (IPP) obse...

atom-lead couplingWithin a new perspective which includes the consideration of spin-up and spin-down electrons, a quantum-box approach is used to find a closed mathematical expression for the quantized electrical conductance of an imperfect point–metal contact. From this expression, both proper and...
A rare pearl of a neutral silicon atom in the formal oxidation state zero seems to evolve best in the oyster-like coordination environment of a bidentate N-heterocyclic carbene ligand. In their Communication on page7147ff., M. Driess and co-workers present the strikingly facile formation of ...
