DOI: 10.1016/j.comptc.2016.12.003

Abstract: Abstract A new development of the Electron Density of Delocalized Bonds formalism (EDDB) is proposed that provides marked improvement in the description of electron delocalization in aromatic rings. Special attention is paid to charged aromatic… read more here.

DOI: 10.1021/acs.inorgchem.0c00254

Abstract: The trilithium compound 1,3-[PhMe2Si-C(Li)═C(H)]2C6H3Li (2b) reacted with BCl3, AlCl3, or GaCl3 by salt elimination to yield dinuclear heptacyclic compounds (4). Two tridentate tricarbanionic ligands coordinate two B, Al, or Ga atoms and adopt a helical… read more here.

Published in 2017 at "Inorganic chemistry"

DOI: 10.1021/acs.inorgchem.6b02503

Abstract: The molecular and electronic structures of the group 7 heptoxides were investigated by computational methods as both isolated molecules and in the solid-state. The metal-oxygen-metal bending angle of the single molecule increased with increasing atomic… read more here.

Published in 2018 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.8b09367

Abstract: Tetrel bonding is the noncovalent interaction of group IV elements with electron donors. It is a weak, directional interaction that resembles hydrogen and halogen bonding yet remains barely explored. Herein, we present an experimental investigation… read more here.

Published in 2018 at "Frontiers in Oncology"

DOI: 10.3389/fonc.2018.00468

Abstract: Background: Neuroblastoma, a neuroendocrine tumor, stems from the developing sympathetic nervous system. Previous genome-wide association studies (GWASs) have discovered a number of neuroblastoma susceptibility genes in Caucasians including LIM domain only 1 (LMO1). Objective: We… read more here.
