On Gödel’s “Platonism” [PDF]

open access: yesPhilosophia Scientiae, 2011
Cet article discute des analyses de Gödel sur la réalité des objets mathématiques. Nous distinguons trois énoncés :(i) Les mathématiques décrivent une réalité non sensible, qui existe indépendamment des actes et des dispositions de l’esprit humain.(ii) Les théories mathématiques ne sont pas créées par l’ego à partir de rien.(iii) Les mathématiques (ou ...

Synthesis, Structure, and Lewis Acidity of Heavy Pnictenium Cations

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A series of donor‐coordinated and donor‐free heavy pnictenium cations were synthesized and structurally characterized. The cations are strong Lewis acids according to experimental (Gutmann–Beckett method) and computational studies (FIAs). Strained pnictanes L1PnNaph (Pn = Sb 1, Bi 2; L1 = 2,6‐(2,4,6‐i‐Pr3C6H2)2C6H3) were synthesized and protonation ...

Impacts of Fluorination at the Ortho‐Position of Carboxy Groups on Tetrakis(biphenyl)ethene‐Based Hydrogen‐Bonded Framework

open access: yesSmall, EarlyView.
This work provides new findings on the effect of fluorination on the substitution of TPE derivatives and the modulation of the structure and fluorescence properties of hydrogen‐bonded organic framework (HOF) of F‐CBPE. ABSTRACT Fluorination of building block molecules is one of the effective engineering approaches to modulate molecular assembly in ...

Platonic sphalerons

open access: yesPhysics Letters B, 2004
We construct sphaleron solutions in Weinberg-Salam theory, which possess only discrete symmetries. Related to rational maps of degree N, these sphalerons carry baryon number Q_B=N/2. The energy density of these sphalerons reflects their discrete symmetries.

Group 13 Aminopyridinato Complexes and Co─Al Heterobimetallics: Impact of Ligand Substituent and Metal Exchange on Thermal Behavior

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
A family of monometallic aluminum and gallium complexes supported by simple aminopyridinato ligands was synthesized and fully characterized by NMR spectroscopy and single‐crystal X‐ray diffraction. In addition, two Co─Al heterobimetallic complexes were synthesized and structurally characterized.
