Here, we report the copper-catalyzed C2 selective cross-dehydrogenative C–N bond formation of azines with azoles. This straightforward method enables us to address the key limitation of prior N–O ...

Rockets carry an oxidizer, often in the form of liquid oxygen, to burn their engine fuel. That’s the fundamental difference between rockets and jets; the latter get oxygen from the air.

The performance of an aluminized formulation with covalently bound dinitrate ester (O2N−O2C−CO2−NO2) was shown to be comparable to that of ammonium perchlorate/aluminum. This makes oxalic acid ...

A novel thermoacidophilic iron and sulfur-oxidizing archaeon, strain YN25, was isolated from an in situ enriched acid hot spring sample collected in Yunnan, China. Cells were irregular cocci, about ...
