Quantum‐Engineered Magnesium Phthalocyanine for Multifunctional Optoelectronics: Charge Transfer Dynamics, Topological Features, and Device‐Level Integration

open access: yesChemistrySelect, Volume 11, Issue 38, 13 October 2026.
ABSTRACT Magnesium phthalocyanine (MgPc) is investigated as an organic semiconductor through a combined theoretical and experimental approach. Density functional theory (DFT) and time‐dependent DFT calculations reveal a moderate HOMO‐LUMO gap (2.16 eV), pronounced π→π* and intramolecular charge‐transfer transitions, and a low exciton binding energy (0 ...

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

open access: yesStructural Concrete, Volume 27, Issue 5, Page 8435-8452, October 2026.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

A Late Cretaceous‐Eocene Geomagnetic Polarity Time Scale (MM26) That Combines Marine Magnetic Anomaly Records, Radioisotopic Dates, and Astrochronology

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Geomagnetic Polarity Time Scale (GPTS) is essential to date geological events in stratigraphic sequences and to reconstruct plate motions. The first GPTSs were based on the record of magnetic anomalies created by seafloor spreading, calibrated by a few radioisotopic dates.

DISCO: a general software tool for dislocation contrast factor calculations in diffraction analysis

open access: yesJournal of Applied Crystallography, Volume 59, Issue 5, Page 1720-1729, October 2026.
DISCO is a program capable of calculating the X‐ray contrast factor for single‐ and polycrystalline materials in real time.Dislocation contrast factors (CFs) play a central role in diffraction‐based analyses of plastic deformation, linking the elastic strain fields generated by dislocations to diffraction line broadening.
