Mechanosynthesis of nanocrystalline CaTi_1-xMnxO_3-δ

Boletín de la Sociedad Española de Cerámica y Vidrio, 2008
The mechanosynthesis of nanocrystalline CaTi1-xMnxO3-δ is reported for the first time. Powdered CaO, TiO2 anatase and Mn2O3 (Aldrich) were weighed in the appropriate stoichiometric quantities in order to obtain CaTi1-xMnxO3-δ (x=0.05, 0.10, 0.15, 0.20, 0.

Testing and Simulation of Multilayer Polyvinylidene Fluoride‐Based Piezoelectric Energy Harvester Devices

Advanced Materials Technologies, EarlyView.
The study considers the use of polymer/dielectric‐based multilayers piezoelectric Energy Harvesters (EH) to produce an output voltage and current, by exploiting the mechanical energy provided by human organs movements. In particular, the heart motion is considered from the kinematic viewpoint, and a multiphysics theoretical model is developed to assess
