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 ...

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.

Crystal structure of fucoxanthin: resolving a long‐standing crystallographic challenge

open access: yesActa Crystallographica Section C, Volume 82, Issue 10, Page 627-633, October 2026.
The first small‐molecule single‐crystal X‐ray structure of fucoxanthin is reported, resolving a long‐standing crystallographic problem in carotenoid structural chemistry.Fucoxanthin (C42H58O6) is a highly functionalized allenic epoxy xanthophyll containing hydroxy, acetoxy, ketone and conjugated polyene units.

The Bureaucratic Paradox of Citizen Agency: Institutional Crowding‐Out in Government‐Catalyzed Co‐Production in Shanghai, China

open access: yesGovernance, Volume 39, Issue 4, December 2026.
ABSTRACT Public service co‐production is often framed as a means of creating public value, yet its dynamics are complex when citizen‐led participation is catalyzed by strong public institutions. This mixed‐methods study examines government‐catalyzed, citizen‐centric co‐production in Shanghai, China, where the state provides institutional support ...

Dietary shrimp by‐product meal as a fishmeal replacement: Effects on growth performance and acute stress responses in juvenile Pacific white shrimp (Penaeus vannamei)

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract Sustainable aquafeed development requires alternative protein sources that reduce dependence on fishmeal without compromising shrimp performance. This study evaluated shrimp by‐product meal (SBM) as a fishmeal replacer in juvenile Pacific white shrimp (Penaeus vannamei) and assessed their responses to acute air exposure stress.

Cancer Risk in Haemodialysis Patients Compared With That in the General Population: A Multicenter Questionnaire‐Based Study in Okinawa, Japan

open access: yesNephrology, Volume 31, Issue 10, October 2026.
This multicenter study evaluated cancer risk among haemodialysis patients in Okinawa, Japan. The risk of colorectal and lung cancer was particularly increased during the first 2 years of dialysis, highlighting the importance of cancer screening during this period.
