Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

open access: yesAdvanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

An Implanted Tooth That Can Feel

open access: yesAdvanced Science, EarlyView.
To endow the implanted tooth with masticatory perception, herein we demonstrate that a 3D‐printed piezoelectric‐core/robust‐sheath implanted tooth can rebuild the sensing feedback, serving as “mechanoreceptors” in converting the mechanical chewing force to electrical signals, and up to brain through surrounding alveolar nerve system.

Bilateral fusion of permanent mandibular incisors with talon's cusp

open access: yesSRM Journal of Research in Dental Sciences, 2017
Fused teeth and talon cusp are developmental anomalies with inherently bizarre anatomy. These anomalies may develop during tooth bud morphodifferentiation as a result of a developmental aberration of both the ectoderm and mesoderm.
