Carbonated Fluorapatite‐Gelatin‐Composites: Morphogenesis and Structure of Kniep's Dumbbells
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Inspired by the pioneering work of Prof. Rüdiger Kniep on fluorapatite‐gelatin nanocomposites also known as “Kniep's Dumbbells,” this study investigates carbonated fluorapatite‐gelatin aggregates synthesized by the double diffusion technique within a gelatin gel.

Cladistics, EarlyView.Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Curriculum Gaps in Periodontal Knowledge Among Medical Students: A Cross‐Sectional Study
European Journal of Dental Education, EarlyView.ABSTRACT Introduction Periodontal disease is a major public health concern with well‐established systemic implications. Despite the increasing emphasis on the periodontal‐systemic health connection, the extent to which periodontal disease is integrated into medical education is still unclear.
