Comparative analysis of various forms of local drug delivery systems on a class 2 furcation – A systematic review

Journal of Pharmacy and Bioallied Sciences, 2023
Class II mandibular furcation defect is a periodontal condition characterized by a cul-de-sac lesion, a definite parallel constituent with only a portion of alveolar bone remaining intact. There may be involvement of vertical bone loss.

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.
