DOI: 10.1002/advs.202104749
Abstract: Due to tunable redox properties and cost‐effectiveness, copper‐ceria (Cu‐CeO2) materials have been investigated for a wide scope of catalytic reactions. However, accurately identifying and rationally tuning the local structures in Cu‐CeO2 have remained challenging, especially… read more here.

DOI: 10.1103/physreva.101.043403
Abstract: Recent studies have confirmed the coupling of optical vortices, such as Laguerre-Gaussian and Bessel-Gaussian modes, to quadrupole-active atomic transitions. This interaction has been shown to be enhanced considerably in the case of Laguerre-Gaussian beams due… read more here.

DOI: 10.1364/prj.5.000436
Abstract: We theoretically propose blue-detuned optical trapping for neutral atoms via strong near-field interfacing in a plasmonic nanohole array. The optical field at resonance forms a nanoscale-trap potential with an FWHM of 200 nm and about ∼370 nm… read more here.
