The existence of a depolarization field in polarized ferroelectric materials was experimentally demonstrated in the 1970s 1,2. In the pioneering work of Wurfel et al. 2, a triglycine sulfate ...
Bone Morphogenetic Protein (BMP) signaling is essential for craniofacial development, though little is known about the mechanisms that govern BMP secretion. We show that depolarization induces calcium ...
