There are 20 amino acids that create the proteins required for life on our planet — and scientists have now found exactly 14 ...

While the composition of gas and dust in a molecular cloud is fairly uniform, everything changes once a star begins to form.

This characteristic allows for the formation ... by the interaction of ammonia (NH 3) with a metal ion. Diffuse Electrons: Electrons that are loosely bound to an atom or molecule and can ...

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 ...

IF ammonium chloride is formed by counter-current diffusion of ammonia and hydrogen chloride gases in a long tube, periodic precipitation of the product in the form of rings is observed.

Early analysis of asteroid samples from NASA’s OSIRIS-REx mission show the residue of an icy brine, and a soup of amino acids ...

Scientists have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission ...

Nonthermal plasma (NTP) has opened unexplored routes for small-scale, decentralized ammonia production. However, understanding the ammonia formation pathways when employing NTP-driven processes is ...

High ammonia levels are toxic and cause symptoms such as headache, confusion, disorientation, excessive sleepiness, and difficulty concentrating. These symptoms reflect ammonia’s dangerous effect on ...

A number of other factors also serve to make ammonia a good fuel source for shipping. In liquid form, it has a high volumetric energy density, 2.7 times greater than hydrogen. And although it must be ...
