Abstract The interplay between constituent localized and itinerant electrons of metal clusters defines their physical and chemical properties. In turn, the electronic and geometrical structures are strongly entwined and exhibit strong size-dependent

The interaction of magnetic dopants with delocalized electron states can result in interesting many-body physics. Here, the magnetic properties of neutral and charged finite silver metal host clusters with a magnetic cobalt atom impurity were investi

Buckyball-metal Complexes as Potential Carriers of Astronomical Unidentified Infrared Emission Bands

The Astrophysical Journal, Vol 952, Iss 1, p 13 (2023)
Efforts over 40 yr still leave the source of astronomical infrared emission bands largely unidentified. Here, we report the first laboratory infrared (6–25 μ m) spectra of gas-phase fullerene-metal complexes, [C _60 -Metal] ^+ (Metal = Fe, V) and

In this paper, we report on the experimental determination of photon emission rates of laser-excited cobalt clusters, Co_{n}^{+} (n=5–23), deduced from fragmentation mass spectrometry and metastable decay fractions. The rates are so high that they

In this study, we applied cluster beam deposition (CBD) as a new approach for fabricating efficient plasmon-based photocatalytic materials. Au nanoclusters (AuNCs) produced in the gas phase were deposited on TiO2 P25-coated silicon wafers with covera

Magnetic deflection studies demonstrate that the magnetic moment per cobalt atom is higher in small cobalt oxide clusters than in pure cobalt clusters.

Inside a spacecraft, the temperature and humidity, suitable for the human crew onboard, also creates an ideal breeding environment for the proliferation of bacteria and fungi; this can present a hazard to human health and create issues for the safe r

The structures of cationic CrSin+ (n = 6–10) clusters were determined by complementary experimental and computation work. Some of the clusters were found to have pairs of enantiomeric isomers.

Individual magnetic transition metal dopants in a solid host usually exhibit relatively small spin excitation energies of a few meV. Using scanning tunneling microscopy and inelastic electron tunneling spectroscopy (IETS) techniques, we have observed
