Polydopamine Coating in Trabecular Bone‐Like Scaffolds With Strontium‐Substituted Nanohydroxyapatite for Bone Tissue Engineering

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
PLA and strontium‐substituted hydroxyapatite filaments were used in 3D printing to fabricate a trabecular‐inspired scaffold. The scaffold was functionalized with a polydopamine coating. Characterization revealed enhanced surface properties and mechanical performance, supporting its potential application in bone tissue engineering.

Oncologic Safety of Facial‐Vessel–Based Buccinator Myomucosal Flaps for Tongue and Oral Floor Reconstruction: A Retrospective Multicenter Case–Control Study

open access: yesHead &Neck, Volume 48, Issue 3, Page 827-836, March 2026.
ABSTRACT Background Buccinator myomucosal flaps (BMFs) have been proposed as a reconstructive solution for defects of the tongue and oral floor; however, their harvest requires preservation of the facial artery and vein. This study aimed to evaluate the oncologic safety of this approach compared with free fasciocutaneous flaps (FFF).

Complementarity of BOLD and ADC‐fMRI in Mapping Brain Visual Processing in the Rat

open access: yesNMR in Biomedicine, Volume 39, Issue 3, March 2026.
BOLD‐fMRI and ADC‐fMRI were acquired at 9.4 and 14 T during visual stimulation with variable frequency. BOLD‐fMRI showed robust positive/negative responses but depended on regional vascularization patterns. ADC‐fMRI was able to detect neural activity independently from vascular effects at 9.4 T.

Experimental Investigations on Mechanics‐Based Additively Manufactured Stayed Lattice Structures

open access: yesPAMM, Volume 26, Issue 1, March 2026.
ABSTRACT Lattice structures have gained increasing popularity due to their remarkable strength‐to‐weight ratio. With advancements in material extrusion additive manufacturing (MEX), the complex designs of lattice structures have become more accessible and widely applicable. However, their slender components are highly susceptible to elastic buckling at

The Dominant Role of the Electron Isotropy Boundary in Controlling Earth's Outer Radiation Belt Electron Lifetimes

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Field‐line curvature scattering (FLCS) is believed to be the primary mechanism forming electron isotropy boundaries (IB) and can rapidly scatter relativistic electrons from the outer radiation belt. However, its direct and quantitative impact on controlling outer belt electron lifetimes has never been directly assessed.
