Advanced Functional Materials, EarlyView.This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...

Piezoelectricity of phospholipids: Are cell membranes also piezoelectric? [PDF]
Biophysical Journal, 2009 Recently it was foundi that mechanical deformation of films of L-α-phosphatidylcholine in the La phase induces an electric polarization. It was suggested that this effect is due to the chiral smectic A (SmA∗) type liquid crystal structure of the bilayers, which under molecular tilt becomes a ferroelectric (SmC∗) phase, where the electric polarization ...
