Unraveling MXene Oxidation Mechanisms Under Realistic Gas Environments by In Situ Gas‐Cell TEM

Advanced Functional Materials, EarlyView.
Real‐time visualization of MXene degradation reveals a fundamental oxidation mechanism under oxygen and moisture environments. Using in situ gas‐cell electron microscopy, this study demonstrates that oxygen degradation drives a thermodynamically controlled high‐temperature transformation into mixed rutile/anatase phases.

Comparative evaluation of platelet-rich fibrin membrane and collagen membrane along with demineralized freeze-dried bone allograft in Grade II furcation defects: A randomized controlled study

Journal of Indian Society of Periodontology, 2018
Background: The management of the furcation areas in multirooted teeth is often challenging due to difficulty in access. Platelet-rich fibrin (PRF), a second-generation platelet concentrate, has shown to accelerate the healing of soft and hard tissues ...

GUIDED TISSUE REGENERATION IN FURCATION DEFECTS

, 2020
One of the indications for guided tissue regeneration (GTR) is furcation lesion. Periodontal regeneration of this type of defects is not predictable, especially in terms of complete bone fill.

Resolving the Structural Duality of Graphene Grain Boundaries

Advanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.
