Synthesis, Characterization, Magnetic Properties, and DFT Investigations of Heterobimetallic Nickel–Lanthanide LNiIILnIII (Ln = Ce, Gd, Tb, Dy) Complexes Supported by Schiff Base Ligands

European Journal of Inorganic Chemistry, EarlyView.
Four 3d4f heterobimetallic Schiff base complexes are designed from the ditopic N,N’‐bis(3‐methoxysalicylaldiimine)‐1,3‐propylene‐2‐ol ligand. Experimental dc magnetic measurements and density functional theory computational investigations converge to antiferromagnetic exchange interaction between Ni(II) and Ce(III) ions while ferromagnetic interaction ...

Strain Effect on the Electronic, Optical, and Mechanical Properties of Inorganic Mg3NBr3 Perovskite: A DFT Study

Energy Science &Engineering, EarlyView.
ABSTRACT This study investigates the potential of lead‐free Mg3NBr3 inorganic halide perovskites for photovoltaic and optoelectronic applications through comprehensive first‐principles density functional theory (FP‐DFT) calculations. This analysis reveals that Mg3NBr3 behaves as an indirect bandgap semiconductor with tunable electronic transitions in ...

What a State: Why the U.S. is Still Bad for Your Health (Policy)

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT The second Trump administration's centrepiece legislation, the modestly‐named Big Beautiful Bill, passed by the House of Representatives and going through the Senate at time of writing, offers an opportunity to reflect upon how the U.S. state affects health policy and the prospects for equitable access to affordable healthcare.

High‐fundamental‐mode output of 1064 nm vertical‐cavity surface‐emitting laser using double embedded antiresonant oxide islands

Information &Functional Materials, EarlyView.
A two‐junction 1064 nm VCSEL with double antiresonant oxide islands in the top DBR is designed to enhance fundamental transverse mode operation. By optimizing island count, aperture size, thickness, and position, it achieves 36.2 mW output power, 54.8% PCE, and a 33.06 GHz 3 dB bandwidth.

Spanning Plane Subgraphs of 1‐Plane Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT A graph drawn on the plane is called 1‐plane if each edge is crossed at most once by another edge. In this paper, we show that every 4‐edge‐connected 1‐plane graph has a connected spanning plane subgraph. We also show that there exist infinitely many 4‐connected 1‐plane graphs that have no 2‐connected spanning plane subgraphs.

Diagrammatic Schemes for Nonlinear Optical Interactions

Journal of Raman Spectroscopy, EarlyView.
Conventional diagrammatic approaches (blue frames in the figure) to semi‐classical nonlinear optical interactions emphasize either the bra and ket matter states (double‐sided Feynman diagrams and Liouville pathways) or the frequencies of the bra and ket radiative processes between energy levels (Albrecht notation). We propose a field‐type modification (
