Polymer Composites, Volume 47, Issue 1, Page 532-542, 10 January 2026.Steric stabilisation of silica nanoparticles suppresses the Payne effect in poly(butadiene) nanocomposites and enables the thickness of the glassy layer to be quantified with QENS experiments. ABSTRACT Silica nanoparticles in polybutadiene nanocomposites cause significantly hindered polymer dynamics in the form of a glassy layer, which can extend more ...

Realization of Complex‐Shaped Magnetic Nanotubes with 3D Printing and Electrodeposition
Advanced Functional Materials, Volume 36, Issue 4, 12 January 2026.Complex‐shaped magnetic nanotubes were fabricated by coating three‐dimensional nanoscaffolds fabricated with focused electron beam induced deposition with a magnetic coating via electrodeposition. X‐ray magnetic microscopy and simulations revealed an azimuthal magnetic configuration within the nanotubes and pinning of domain walls at curved vertices ...

Advanced Materials, Volume 38, Issue 1, 2 January 2026.This study reveals an atomic‐level correlation between bulk dislocations and the exsolution of surface nanoparticles through a novel approach for dislocation engineering in epitaxial thin films. Employing in situ scanning transmission electron microscopy, two primary reasons for the frequent nucleation of dislocation‐associated nanoparticles are ...

Limits from rapid TeV variability of Mrk 421
, 1997 The extreme variability event in the TeV emission of Mrk 421, recently reported by the Whipple team, imposes the tightest limits on the typical size of the TeV emitting regions in Active Galactic Nuclei (AGN).

Advanced Science, Volume 13, Issue 2, 9 January 2026.The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

The Interstellar Medium of IRAS 08572+3915 NW: H3+ and Warm High Velocity CO
, 2006 We confirm the first detection of the molecular ion H3+ in an extragalactic object, the highly obscured ultraluminous galaxy IRAS 08572+3915 NW. We also have detected absorption lines of the fundamental band of CO in this galaxy.
