Optimizing piezoelectric transformer for maximum power transfer [PDF]
Smart Materials and Structures, 2003 The piezoelectric transformer should be considered as not only a mechanical system but also an electrical fully coupled system, which uses finite structure resonance to perform voltage conversion. The traditional piezoelectric transformer uses an equivalent circuit concept to simulate its mechanical motion.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Design of Asymmetrical Relay Resonators for Maximum Efficiency of Wireless Power Transfer
International Journal of Antennas and Propagation, 2016 This paper presents a new design method of asymmetrical relay resonators for maximum wireless power transfer. A new design method for relay resonators is demanded because maximum power transfer efficiency (PTE) is not obtained at the resonant frequency ...
