Researchers developed an yttrium doped nickel catalyst that creates stable oxygen vacancies to improve ammonia decomposition for clean hydrogen production. Ammonia carries a high density of hydrogen ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

A key new insight from the study is that ammonia complex etching—an unusual method that avoids non-selective dissolution of traditional etching—successfully creates nickel-cobalt Prussian blue analog ...

Ammonia complexes represent a versatile class of compounds that have attracted considerable interest due to their unique electronic structures and emergent reactivity. These systems, which involve the ...

A multi-institution research team has prepared the first two-coordinate transition-metal complex containing an imido ligand. This coordinatively unsaturated nickel(II) complex demonstrates enhanced ...
