A Three‐Dimensional Structural Model for Predicting Magnetic Exchange and Hydrogen Positions in Bis‐μ‐Hydroxido Cu(II) Dimers

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Magneto‐structural correlation in bis‐μ‐hydroxido Cu(II) dimers: The out‐of‐plane angle (α) of bridging hydroxido groups critically influences the exchange coupling constant (J). A three‐dimensional correlation combining α and the Cu‐OH‐Cu angle (θ) enables computationally accurate J prediction.

Phenolate‐ and Alcoholate‐Based Chromium N‐Heterocyclic Carbene Complexes: Structural Peculiarities, Magnetometric and Electron Paramagnetic Resonance Study, and Catalytic Ethylene Oligomerization

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The first low‐oxidation (I/III) state chromium‐complex bearing a O‐chelating NHC ligand has been synthesized and structurally characterized by single‐crystal X‐ray analysis. The formation of the mixed‐valence species was further supported by SQUID magnetometry and high‐field electron paramagnetic resonance (EPR) spectroscopy.

Jet Flow Field Analysis of Convergent‐Divergent Nozzle for Hydraulic Perforation for Natural Gas Hydrates

open access: yesEnergy Science &Engineering, EarlyView.
Combining the nozzle structure and wellbore size of the second natural gas hydrate trial production, the CFD is employed to analyze the internal and external flow fields of convergent–divergent cavitation nozzle. Analyzing the influence of various structural parameters of the nozzle on its jet performance, and the nozzle configuration with optimal jet ...

On Kotzig's Perfect Set Problem of Hamiltonian Cycle Decompositions of the Complete Graph

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamiltonian cycle decomposition (HCD) of K n ${K}_{n}$ is a set of Hamiltonian cycles in which each 1‐path of K n ${K}_{n}$ appears exactly once. A Dudeney set of K n ${K}_{n}$ is a set of Hamiltonian cycles in which each 2‐path of K n ${K}_{n}$ appears exactly once.

Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

open access: yesLaser &Photonics Reviews, EarlyView.
This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...
