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 ...

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Probing Effects of Electron Addition to Polycyclic Conjugated Hydrocarbons Containing Four‐Membered Rings

ChemistryEurope, EarlyView.
Studies of the mono‐ and doubly reduced cyclobutadienoid derivatives with increasing conjugation length reveal that the two‐electron addition does not allow the four‐membered rings to achieve the aromatic square shape, instead resulting in the distorted rectangular or trapezoid geometries, even at the cost of losing aromaticity of the fused benzenoid ...

Influence of Compactness and Crystallinity on Hole Transfer Ability of Nickel Oxide Layer in Modal Coupling Regime

Chemistry – A European Journal, EarlyView.
This study investigates how structural properties influence the hole migration behavior of nickel oxide (NiOx). Our findings reveal that both crystallinity and compactness significantly affect the hole transport capability of NiOx layers. The Au‐NPs/NiOx/Pt‐film photocathode exhibited cathodic photocurrent at wavelengths below 800 nm, with a maximum ...
