Has the Nobel Prize evolved into a driving force for scientific progress or a hindrance?
Reflections on today’s Nobel Prize in Physics awarded for neutrino research.
All-metal aromaticity. III. σ- and π-double aromaticity
Two definitions of double aromaticity of organic and inorganic aromatic compounds: two distinct circuits; σ- and π-electrons within the same ring. This study clarifies σ-aromaticity, σ-delocalization, σ-electrons, σ-bonds to define clearly the doubled aromaticity and the origin of antiaromaticity.
All-metal aromaticity. II. Square-planar aromatic clusters
Square-planar aromatic metal clusters have been classified as σ-, π-, δ-, and φ-aromaticity. Detailed analysis of specific examples reveals that, much like organic aromatic cyclic compounds such as furan, pyrrole, and thiophene, these clusters contain only lone-pair electrons and π electrons [1].
All-metal aromaticity. I. Smallest triangular aromatic cyclo-clusters
Despite the simple three-membered ring structures, they exhibit different mechanisms.
Type 1: Bi33--like. Type 2: C3H3+-like. Type 3: H3+-like. Type 4: Na2Ga3H3 cluster.
The ring current and its induced magnetic field are the necessary and sufficient conditions for the existence of aromaticity.

Key findings around electrons. A mini-review
I recently published five articles in a row: “New understanding of atomic structure”, “Re-understanding of wave-particle duality”, “Electron motion in graphene”, “The movement of two parallel unpaired electrons in benzene and aromatic compounds”, and “Real structure of water molecule”.
