Journal of Anatomy, EarlyView.The present study characterized newt digital flexor tendon regeneration structurally at both micro‐ and nanoscales following complete transection and suggested that the mechanism of tissue regeneration differs between the early phase (until 6 weeks) and the late phase (after 6 weeks). Tendon stubs remained separated for up to 2 weeks after transection,

Dislocation interaction with a tilt low‐angle grain boundary in bi‐crystal SrTiO3
Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.A low‐angle tilt grain boundary (GB) was fabricated in SrTiO3 to study the dislocation and GB interaction at mesoscale. Dislocations were generated using Brinell indentation. Dislocation etch pit method and TEM observations both confirm dislocation pileup, storage, and transmission across the GB.

Direct observation of dislocation plasticity in high-Mn lightweight steel by in-situ TEM
Scientific Reports, 2019 To gain the fundamental understanding of deformation mechanisms in an aluminum-containing austenitic high-Mn steel (Fe-32Mn-8.9Al-0.78 C (wt.%)), in-situ straining transmission electron microscopy (TEM) analysis is conducted.

Olivine Deformation: To B Slip or Not to B Slip, That Is the Question
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract When deformed by dislocation creep the dominant slip (Burgers) vectors of olivine dislocations are parallel to [100] or [001]. Dislocations with an [010] Burgers vector component (b dislocations) have been recorded rarely. Here we show an experimentally deformed olivine sample has a substantial population (17%) of b dislocations.

Consequences of the CMR effect on EELS in TEM
, 2017 Double perovskite oxides have gained in importance and exhibit negative magnetoresistance, which is known as colossal magnetoresistance (CMR) effect. Using a La$_2$CoMnO$_6$ (LCM) thin film we prove that the physical consequences of the CMR effect do ...

Interface Engineering and Oxygen Vacancy Control in SrTiO3‐TiO2 Eutectics
Advanced Materials Interfaces, Volume 12, Issue 24, December 22, 2025.The thermal annealing of the SrTiO3‐TiO2 eutectic under various gaseous environments (vacuum, air, oxygen, argon) allows to significantly enhance the formation of a sharp interface between the two crystalline phases and to control the concentration of the oxygen vacancies within the composite material.
