Covalent organic frameworks (COFs) are covalently linked crystalline reticular materials with highly ordered structures and permanent porosity. Due to the designable structures and controllable ...

The photocatalytic water oxidation process plays a vital role in attaining efficient solar-to-chemical process by enabling photocatalytic water splitting and CO 2 /N 2 fixation. However, the lack of ...

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 ...

Both the Co meso-tetraphenyl porphyrin catalyst and the alcohol reactant can be gathered on the surface of mono-(6-mercapto-6-deoxy)-β-cyclodextrin-decorated CdS nanocrystals via bidirectional ...

Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the majority of organic compounds. In 1931, the Nobel Laureate Linus Pauling ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...
