Deeper Insights into the Morphology Effect of NaTiO Nanoarrays on Sodium-Ion Storage.

NaTiO-based anodes show great promise for Na storage in sodium-ion batteries (SIBs), though the effect of NaTiO morphology on battery performance remains poorly understood. Herein, hydrothermal syntheses is used to prepare free-standing NaTiO nanosheets or NaTiO nanotubes on Ti foil substrates, with the structural and electrochemical properties of the resulting electrodes explored in detail. Results show that the NaTiO nanosheet electrode (NTO NSs) delivered superior performance in terms of reversible capacity, rate capability, and especially long-term durability in SIBs compared to its nanotube counterpart (NTO NTs).

A New Al O -Protected EB-PVD TBC with Superior CMAS Resistance.

Calcium-magnesium-aluminium-silicate (CMAS) attack is a longstanding challenge for yttria stabilized zirconia (YSZ) thermal barrier coatings (TBCs) particularly at higher engine operating temperature. Here, a novel microstructural design is reported for YSZ TBCs to mitigate CMAS attack. The design is based on a drip coating method that creates a thin layer of nanoporous Al O around YSZ columnar grains produced by electron beam physical vapor deposition (EB-PVD).

High Power Factor Nb-Doped TiO Thermoelectric Thick Films: Toward Atomic Scale Defect Engineering of Crystallographic Shear Structures.

Donor-doped TiO-based materials are promising thermoelectrics (TEs) due to their low cost and high stability at elevated temperatures. Herein, high-performance Nb-doped TiO thick films are fabricated by facile and scalable screen-printing techniques. Enhanced TE performance has been achieved by forming high-density crystallographic shear (CS) structures.
