Multiple bonds between heavier main-group elements may exhibit different properties and reactivity compared with their second-row counterparts. Now it has been shown that a NHC-stabilized phosphasilyne, a heavier analogue of nitrile, undergoes thermal isomerization to yield a phosphasilenylidene; this ...
ResearchOpen Access30 Dec 2024Nature Communications Volume: 15, P: 10763 Neutral 4π-electron tetrasilacyclobutadiene contains unusual features of a Möbius-type aromatic ring Introducing main group elements into neutral and charged cyclobutadienes enables the fine-tuning of their stability and electro...
Meanwhile, the rich oxygen-containing groups and N-elements could be noted, inducing the evolution of electron-moving behaviors. More significantly, assisted by the inter-facial C-Se bonds and tiny Se distributions, Se electrodes are activated during cycling. Used as cathodes for Na-Se systems, ...
From this study, migration of the active elements in perovskite is found to be an effective strategy to increase the quantity and activity of active sites, providing new insights and under-standing for designing efficient OER catalysts. A comprehensive modification enables the high rate capability ...

The structure-affinity relationship revealed the key structural elements and preferred substituents at specific sites of flavonoids related to binding affinity with zein. The synchronous, ANS-binding fluorescence and FT–IR spectra confirmed that flavonoids induced a conformational change in zein secondary ...

The first one is a historical reason. At the beginning of the study of the various compounds formed by rare earth (R.E. or, shortly, R) elements, only the R2O3 oxides and some salts were available as starting materials for the preparation of the sulfides, and the chemists had no ...
