The effect of reagents on the structure and performance of sodium‐layered oxides has not yet been thoroughly studied. This work explored this factor systematically through in situ high‐temperature XRD. The samples synthesized via MnCO3‐based precursors form the Li2MnO3 phase at evaluated temperature and perform better than those through MnO2‐based ...

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin
The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

Causal Association Between Lifestyle Behavior and Potential Risk Factors With Blepharoptosis
ABSTRACT Background Blepharoptosis is among the most common disorders of eyelid malposition that may influence appearance and damage visual function, and both of these can have negative effects on the quality of life. Various types of blepharoptosis have been reported, including neurogenic, traumatic, congenital, mechanical, psychogenic, and myogenic ...
