Syria's de facto leader Ahmed al-Sharaa was declared president for a transitional phase on Wednesday (January 29), tightening his hold on power less than two months after he led a campaign that ...
Researchers developed a sodium-doped amorphous SiBN catalyst, showcasing its potential for small molecule activation and ...
Transition metals have long been used as catalysts to activate small molecules and turn them into valuable products. However, as these metals can be expensive and less abundant, scientists are ...
Heterogeneous catalysts speed up chemical reactions by being in a different state than the reactants. They are efficient and ...
A sodium-doped, transition metal-free amorphous SiBN ceramic, composed of silicon (Si), boron (B), and nitrogen (N), was designed for small molecule activation and catalysis. The strategic ...
