Ti3C2Tx MXene‐Zirconium Diboride Based Ultra‐High Temperature Ceramics
This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...

BaTiO3‐based polymorphic relaxor ferroelectrics are engineered by mesoscopically chemical homogeneity, constructing diversified nanodomain architectures with similar multiple local symmetries but different nanodomain scales in diverse grains. Ex‐/In situ multiscale structure analysis indicates that a relatively continuous polarization switching with ...

The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...

Impact of Microstructural Properties on Ionic and Heat Transport in NaSICON Glass Ceramics
With glass ceramics made from NaSICON materials, everything is about microstructure and glass phase content. Their influence is investigated with regard to the transport properties, both for ionic and thermal conductivity. Small, nm‐sized tubular porosity is regarded as the transport path of Na2O depletion during sintering and as an additional ...

Lithium dendrite causes short‐circuit quickly in liquid lithium metal batteries using a normal separator. By in situ coating Li3PO4 on Li6.5La3Zr1.5Ta0.5O12 (LLZTO), we neutralize the residual alkali on LLZTOsurface, making it feasible to prepare a slurry with PVDF to further coating the separator.

Co enhances the ORR activity while Fe facilitates the cathode/electrolyte interfacial proton conduction. Below 650°C, the H‐SOFC performance is limited by ORR activity so that a high Co/Fe ratio is suggested, whereas above 650°C, a low Co/Fe ratio is favored as the limiting factor shifts to proton conduction.
