The discovery of carbon fullerene cages and their solids opened a new avenue to build
materials from stable cage clusters as “artificial atoms” or “superatoms” instead of atoms …

Borophene, a 2D allotrope of boron and the lightest elemental Dirac material, is the latest
very promising 2D material owing to its unique structural and electronic characteristics of the …

In the last decades, experimental techniques in conjunction with theoretical analyses have
revealed the surprising structural diversity of boron clusters. Although the 2D to 3D transition …

The lattice structure of monolayer borophene depends sensitively on the substrate yet is
metallic independent of the environment. Here, we show that bilayer borophene on Ag (111) …

Conspectus With three valence electrons and four valence orbitals, boron (2s22p1) is an
electron-deficient element, resulting in interesting chemical bonding and structures in both …

Size-selected negatively-charged boron clusters (Bn−) have been found to be planar or
quasi-planar in a wide size range. Even though cage structures emerged as the global …

Conspectus Isolated boron clusters exhibit many intriguing properties, which have only
recently been unfolding with the hand-in-hand advancement of state-of-the-art experimental …

Photoelectron spectroscopy combined with quantum chemistry has been a powerful
approach to elucidate the structures and bonding of size-selected boron clusters (B n−) …

Being intermediate between small compounds and bulk materials, nanoparticles possess
unique properties different from those of atoms, molecules, and bulk matter. In the past two …

Lanthanide (Ln) elements are generally found in the oxidation state+ II or+ III, and a few
examples of+ IV and+ V compounds have also been reported. In contrast, monovalent Ln (+ …
