Cathode Processing Optimization Toward Solid‐State Batteries with Monolithic Oxysulfide Glassy Solid Electrolytes

Batteries &Supercaps, EarlyView.
Mixing order and mixing time affect the ionic and electronic transport properties through a composite cathode made from lithium iron pyrophosphate, an oxysulfide glassy solid electrolyte, and conductive carbon. It is proposed that optimized milling conditions help create robust conduction networks in the composite. Seeking to further the development of

Atomically ordered solute segregation behaviour in an oxide grain boundary

Nature Communications, 2016
Solute segregation is challenging to experimentally identify at the atomic scale. Here, the authors report the direct observation of atomic site-dependent solute segregation behaviour in an yttria-stabilized zirconia grain boundary by atomic-resolution ...

Role of promoters over yttria‐zirconia supported Ni catalyst for dry reforming of methane

Energy Science & Engineering, 2023
Dry reforming of methane (DRM) bears great hope for the catalytic community as well as environmentalists for its potential to convert two greenhouse gases, CH4 and CO2, together into synthetic feedstock “syngas”.

Restoration of human tooth enamel

BMEMat, EarlyView.
Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

Direct application of cobaltite-based perovskite cathodes on the yttria-stabilized zirconia electrolyte for intermediate temperature solid oxide fuel cells

, 2016
In this communication, cobaltite-based perovskite (CBP) cathodes are directly applied on the yttria-stabilized zirconia (YSZ) electrolyte via an in situ assembly process without the addition of a doped ceria interlayer and pre-sintering at high ...

Lead‐Free (K0.5Na0.5)NbO3 Unmodified Piezoceramics: A Reduction in the Energetic Budget of Solid State Synthesis and Sintering

Chemistry–Methods, EarlyView.
The temperature of the solid‐state synthesis of pure (K0.5Na0.5)NbO3 piezo‐composition is reduced by using the niobium pentoxide reactant in the mixture of reagents after attrition milling for only 3h: a majoritarian (57 wt.% of the total Nb2O5 content) orthorhombic polymorph Pbam.
