We report on the strong field ionization of small transition metal clusters (nickel, Ni(n) n=1-36) within the quasistatic regime at an infrared wavelength of 1.5 microm and at intensities up to 2 x 10(14) W/cm(2). From ion yields in a constant axial intensity beam, we obtained saturation intensities for the individual Ni(n) clusters. As compared to quasistatic, single active electron calculatio...

The X-ray absorption cross section ahove the L edges in Xenon gas has been measured using synchrotron radiation. Multielectron excitation effects are investigated over a few hundred eV region from the Xe-LI, LII. and LIII edges and thc contrihutions from the effects of shakenp and shakeoff to the photoahsorption spectrum are elucidated. Several features for the multielectron excitations were de...

Investigations of two-dimensional electron systems (2DES) have been achieved with two model experimental systems, covering two distinct, non-overlapping regimes of the 2DES phase diagram, namely the quantum liquid phase in semiconducting heterostructures and the classical phases observed in electrons confined above the surface of liquid helium. Multielectron bubbles in liquid helium offer an ex...

Significant challenges remain for developing efficient catalysts in an electrochemical multielectron CO2 reduction reaction (CO2RR), which usually suffers from poor activity and selectivity. Motivated by the recent experimental progress fabricating dual-metal atom (DMACs) N-doped graphene materials (graphene-N6V4; N: nitrogen V: vacancy), we sampled eight types of homonuclear (N6V4-M2, M = Cr, ...

Oiscussed in the paper is the mixed scenario of charged liquid surface reconstruction when the surface 20 charge density is c1o$e to the saturation . The basic building block of the arising honeycomb structure is shown to be a modifie multielectron dimple.

Light, inexpensive, effective: Nanostructured Co(3)O(4) clusters (see picture) in mesoporous silica are the first example of a nanometer-sized multielectron catalyst made of a first-row transition-metal oxide that evolves oxygen from water efficiently. The nanorod bundle structure of the catalyst results in a very large surface area, an important factor contributing to the high turnover frequency.
