High Cooling Rate for LRE123 Stoichiometry Control in Preparation of High‐Tc Bulk Superconductors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review presents the cooling‐rate‐control melt‐growth (CRCMG) method as an effective strategy for regulating LRE123 cation stoichiometry. By accelerating the cooling rate during crystallization, oxygen vacancies are increased in the growing lattice, which suppresses LRE3+/Ba2+ substitution and yields near‐ideal 1:2:3 stoichiometry with enhanced ...

Woven Words: Women and Classic Maya Hieroglyphic Writing

Feminist Anthropology, EarlyView.
Abstract What survives of Classic Maya (250–925 CE) scribal tradition suggests that production and use of hieroglyphs were dominated by elite men. Ancient texts and imagery, as well as ethnohistorical sources, overwhelmingly position males as agents of writing.

Assessment of Human Thermal Stress Dynamics and Regional Drivers Across the Arabian Peninsula During 1990–2022 From Observations

International Journal of Climatology, EarlyView.
The results reveal that thermal stress varies substantially across the four AP regions, with winter cold stress in Region I, year‐round heat stress in Region II, pronounced summer heat stress in Region III, and persistent strong to very strong heat stress from late spring to early autumn in Region IV.

Scanning‐Tip and Confocal Raman Characterization of Gold Nanoparticles as Plasmonic Structures for Molecular Sensing

Journal of Raman Spectroscopy, EarlyView.
We apply a sharp silicon tip, typically used for atomic force microscopy (AFM), as a nanoscale probe, and collect frequency‐shifted photons resulting from Raman scattering within the sharp tip. This approach allows us to map local electromagnetic fields in various plasmonic structures and study field “hotspots” with nanometer spatial resolution ...
