Synthesis, Structures, and Properties of Dehydrobiphenyleno[12]Annulenes: Carbon‐Rich Compounds Comprising Two Different Antiaromatic Units

Chemistry – An Asian Journal, EarlyView.
Carbon‐rich compounds dehydrobiphenyleno[12]annulenes (DBP[12]As) comprising antiaromatic four‐membered rings (4MR) and 12‐membered ring (12MR) were synthesized and characterized. DBP[12]As feature high HOMO energy levels and narrow HOMO‐LUMO gaps. The 4MRs have stronger antiaromatic character than the 12MR in DBP[12]As. Abstract In this work we report

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

Astronomische Nachrichten, EarlyView.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Iridium‐Doped Monoclinic Zirconia as a Catalyst for the Oxygen Evolution Reaction

ChemCatChem, EarlyView.
Using density functional theory, we study Ir‐dopings of the monoclinic ZrO2${\rm ZrO}_2$ (1¯11$\bar{1}11$) surface in search of an Ir‐lean catalyst for the oxygen evolution reaction. These are found to be metastable compared to the separate phases of IrO2${\rm IrO}_2$ and ZrO2${\rm ZrO}_2$.

The Simple Harmonic Oscillator [PDF]

, 2017
AbstractThis chapter will introduce a system that is fundamental to our understanding of more physical phenomena than any other. Although the “simple” harmonic oscillator seems to be only the combination of the most mundane components, the formalism developed to explain the behavior of a mass, spring, and damper is used to describe systems that range ...

Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes
