Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

Advanced Functional Materials, EarlyView.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.

Microstructure and Mechanical Properties of AZ31/ZrO2 Composites Prepared by Friction Stir Processing With High Rotation Speed

Frontiers in Materials, 2020
The nano-ZrO2-reinforced AZ31 alloy composites were fabricated by friction stir processing with three multi-passes and high rotation speeds. The AZ31/2.14 vol% ZrO2, AZ31/4.29 vol% ZrO2, and AZ31/6.43 vol% ZrO2 composites were designed.

Multiscale Structuring of Hydroxyapatite via Two‐Photon Lithography of Nanocomposites

Advanced Functional Materials, EarlyView.
Hydroxyapatite scaffolds are of great interest in bone tissue engineering applications, ranging from 3D cell culture to regenerative medicine. Using two‐photon lithography of a transparent nanocomposite, hydroxyapatite microstructures with features ranging from submicron to centimeter‐scale are fabricated. This allows to mimic the natural bone geometry,

Dual‐Interface‐Dominant Cathode Architectures Enabling Fast Sulfur Redox and Stable Interfaces in All‐Solid‐State Li‐S Batteries

Advanced Functional Materials, EarlyView.
An optimized carbon host nanostructure enables a dual‐interface‐dominant architecture in sulfur cathodes of solid‐state Li‐S batteries by selectively forming sulfur|carbon and sulfur|solid electrolyte interfaces. This tailored interfacial configuration accelerates sulfur redox kinetics by establishing enriched Li+/e– transport networks, while ...

Synthesis and characterization of [BaO-(10-x)ZrO2-TiO2-SiO2-xCrO3] type glass and glass ceramics

Journal of Asian Ceramic Societies, 2020
Various glass compositions were prepared in a glassy system [25BaCO3-(10-x) ZrO2-20TiO2-45SiO2-xCrO3] (x = 0, 2, 4, and 6) using melt-quenching technique. XRD patterns of glass and glass ceramics showed amorphous and crystalline nature.

Electro‐Chemo‐Mechanical Coupling in Hf0.5Zr0.5O2 Ferroionic Heterostructures

Advanced Functional Materials, EarlyView.
Schematic of a ferroionic HZO heterostructure where epitaxial interfaces enable dynamic oxygen‐vacancy exchange, coupling ionic and ferroelectric degrees of freedom. Vacancy‐mediated polarization modulation biases HZO polymorphism, suppresses leakage, and enhances piezoelectric response, yielding distinct butterfly‐loop evolution and diode‐like ...

Particle size effect of ZrO2 supports on catalytic liquid-phase oxidation of phenol over Pt/CeO2-ZrO2-Bi2O3/ZrO2 catalysts

Journal of Asian Ceramic Societies, 2020
The size effect of the ZrO2 support on the catalytic activity for the liquid-phase oxidation of phenol was demonstrated over Pt/CeO2-ZrO2-Bi2O3/ZrO2-X catalysts. Here, we selected six types of size-controlled ZrO2-X (X: A–F) (ZrO2-A: 35 nm, ZrO2-B: 22 nm,
