    Silver single atoms and nanoparticles on floatable monolithic photocatalysts for synergistic solar water disinfection by Jian Wang, Jiahe Zhang, Yang Li, Xinghui Xia, Hengjing Yang, Jae-Hong Kim, Wen Zhang

    Published 2025-01-01
    “…Here we prepare a floatable monolithic photocatalyst with ZIF-8-NH2 loaded Ag single atoms and nanoparticles (AgSA+NP/ZIF). Atomically dispersed Ag sites form an Ag−N charge bridge, extending the lifetime of charge carriers and thereby promoting reactive oxygen species (ROS) generation. …”

    Analogous Atomic and Electronic Properties between VN and VNCB Defects in Hexagonal Boron Nitride by Chang-Youn Moon, Kee-Suk Hong, Yong-Sung Kim

    Published 2022-01-01
    “…Noting that carbon has one more valence electron than boron species, our finding naturally points to the correspondence between VN and VNCB defects with one charge state difference between them, which is indeed confirmed by the similarity of atomic symmetries, density of states, and excitation energies. …”

    Probes for 4th Generation Constituents of Dark Atoms in Higgs Boson Studies at the LHC by M. Yu. Khlopov, R. M. Shibaev

    Published 2014-01-01
    “…The nonbaryonic dark matter of the Universe can consist of new stable charged species, bound in heavy neutral “atoms” by ordinary Coulomb interaction. Stable U- (anti-U)quarks of 4th generation, bound in stable colorless (U- U- U-) clusters, are captured by the primordial helium, produced in Big Bang Nucleosynthesis, thus forming neutral “atoms” of O-helium (OHe), a specific nuclear interacting dark matter that can provide solution for the puzzles of direct dark matter searches. …”
