Active high-entropy photocatalyst designed by incorporating alkali metals to achieve d0+d10+s0 cationic configurations and wide electronegativity mismatch
Jacqueline Hidalgo-Jimenez, Taner Akbay, Tatsumi Ishihara +1
Photocatalytic hydrogen (H2) production and carbon dioxide (CO2) conversion to methane (CH4) are considered promising solutions for reducing CO2 emissions. However, the development…
Ubiquitous Antiparallel Domains in 2D Hexagonal Boron Nitride Uncovered by Interferometric Nonlinear Optical Imaging
Yeri Lee, Juseung Oh, Kyung Yeol Ma +10
Hexagonal boron nitride (hBN) supports a wide range of two-dimensional (2D) technologies, yet assessing its crystalline quality over large areas remains a fundamental challenge. Bo…
Understanding high photocatalytic activity of the TiO2 high-pressure columbite phase by experiments and first-principles calculations
Jacqueline Hidalgo-Jimenez, Taner Akbay, Tatsumi Ishihara +1
The clean production of hydrogen as a zero-emission fuel can be done using photocatalysis, with TiO2 being one of the most promising photocatalysts. However, the activity of TiO2 a…
Metallic glasses heterogeneous and time sensitive small scale plasticity probed through nanoindentation and machine learning clustering
S. Pomes, T. Suzuki, T. Enokizono +3
Small-scale plasticity and creep behavior of a Zr-based BMG were investigated using nanoindentation. Four load functions, differing only in hold times of 0, 10, 30, and 60 seconds…
Bulk Nanostructured Zirconia Ceramics with High Hardness and Toughness via Integration of High-Pressure Torsion and Spark Plasma Sintering
Kaveh Edalati, Koji Morita, Shivam Dangwal +1
Developing nanostructured bulk ceramics is a major challenge when conventional high-temperature sintering is employed for consolidation. In the current investigation, yttria-stabil…
Structure determination of flat honeycomb Bi grown on Ag(111)
Ziyong Zhang, Xiaobin Chen, Takeshi Nakagawa
Honeycomb bismuthene structures on Ag(111) were investigated using low-energy electron diffraction (LEED) and density functional theory. LEED I(V) analysis revealed that 0.5 monola…
Influence of interphase boundary coherency in high-entropy alloys on their hydrogen storage performance
Shivam Dangwal, Kaveh Edalati
High-entropy alloys (HEAs) have potential for storing hydrogen reversibly at room temperature due to their tunable thermodynamics; however, they usually suffer from the issue of di…
Severe Plastic Deformation of Ceramics by High-Pressure Torsion: Review of Principles and Applications
Kaveh Edalati, Jacqueline Hidalgo-Jiménez, Thanh Tam Nguyen +8
Ceramics are typically brittle at ambient conditions due to their covalent or ionic bonding and limited dislocation activities. While plasticity, and occasionally superplasticity,…
Spin wave resonance in yttrium iron garnet stripe domains
Daniel Prestwood, Chris E. A. Barker, Kilian D. Stenning +15
We study a thin film yttrium iron garnet sample that exhibits magnetic stripe domains due to a small perpendicular magnetic anisotropy. Using wide-field magneto-optic Kerr effect m…
