Deformación plástica de compuestos mullita/óxido de itrio
Boletín de la Sociedad Española de Cerámica y Vidrio, 2001 Mullite (3Al2O3.2SiO2) based composites have excellent mechanical and thermal properties. The same characteristics that give mullite good resistance to plastic deformation also make its sintering difficult.

Journal of Advanced Materials in Engineering, 2010 The addition of ZrO2 particles to the HA coating has received considerable attention because ZrO2 particles increase the bonding strength between HA coating and substrate. In this study, nanostructured hydroxyapatite (HA)/yttria stabilized zirconia (YSZ)

Ferroionic Electrostatic Landscapes Enabling Wireless Energy Harvesting, Storage, and Sensing
Advanced Electronic Materials, EarlyView.By integrating experiments and electrostatic field simulations, we show that long‐range wireless coupling in Li‐based ferroionics devices emerges from the cooperative interaction between ionic migration and electronic polarization. This coupling sustains self‐polarized electrostatic fields across centimeter‐scale air gaps without external bias or ...

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells
Advanced Energy Materials, EarlyView.Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...
