Persistent Luminescent Nanoparticle-Loaded Filaments for Identification of Fabrics in the Visible and Infrared

Nanomaterials
Persistent luminescent materials are those which can store an amount of energy locally and release it slowly in the form of light. In this work, persistent luminescent nanoparticles (PLNPs) were synthesized and incorporated into polypropylene (PP ...

From Photons to Persistent Memory: Optically Controlled Trap Engineering Enables Secure, Hierarchical Optical Storage

National Materials, Volume 1, Issue 1, Page 16-23, July 2026.
This work demonstrates a novel optical storage method using a tailored electron‐trapping phosphor, MgGeO3:Mn,Yb,Eu. Up‐conversion charging enables high‐resolution writing via two‐photon ionization, whereas trap engineering uses ambient light to shift electrons between traps.

Multiple Rebrightenings in the Optical Afterglow of GRB 210731A: Evidence for an Asymmetric Jet

The Astrophysical Journal
The broadband afterglow of gamma-ray bursts (GRBs) is usually believed to originate from the synchrotron radiation of electrons accelerated by the external shock of relativistic jets.

Air Dielectric Barrier Discharge Plasma on Hydrated Gel Surfaces: Disinfection Performance, Regrowth, and Interfacial Mechanisms

Plasma Processes and Polymers, Volume 23, Issue 7, July 2026.
Air dielectric barrier discharge plasma rapidly disinfects hydrated gel surfaces, but durable control depends on gel chemistry and post‐treatment recovery. High‐salt agar shows strong matrix‐enhanced inactivation and residual inhibitory activity, whereas PVA hydrogels show lower inactivation and rebound under nutrient enrichment.

Comparison of Lightning Channel Luminosity Versus Time Profiles in the Infrared and Visible Ranges

Geophysical Research Letters
Infrared (IR) luminosity of lightning channel in the 3–5 μm range usually persisted throughout the entire interstroke interval, which is in contrast to the simultaneously recorded visible (0.4–0.8 μm) luminosity that always decayed to an undetectable ...

Mechanoluminescent Mixed‐Anion Borate Sr2B5O9Cl:Eu for Dynamic Anticounterfeiting

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Mechanoluminescence (ML)—the emission of light in response to mechanical stimuli—offers a direct and visually intuitive route for transducing mechanical information into optical signals. Herein, we report a mixed‐anion strategy to prepare mixed‐anion borate Sr2B5O9Cl:Eu phosphors through a facile, low‐temperature, and ambient‐atmosphere solid ...

Easily Accessible and Up‐Scalable Aliphatic Bis‐Formamides with Afterglow Luminescence: Photoluminescence Properties and Applications

Small, Volume 22, Issue 42, 27 July 2026.
A bis formamide molecule was found to feature afterglow properties, in both crystalline powder state and in polyvinyl alcohol films. This was attributed to the intermolecular packing that allows H‐trapped emitting state and/or clustering‐triggered emission, which was intensified upon insertion of tetramethylbenzidine as a doping agent.

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, Volume 33, Issue 4, Page 1022-1035, July 2026.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,
