Intracellular protein trafficking and secretion of proteins into the extracellular environment are sequential and tightly regulated processes in eukaryotic cells. Conventionally, proteins that are ...

In combustion reactions, a fuel reacts with an oxygen-rich substance called an oxidizer, creating waste products that often include water and carbon dioxide. But the Vatican’s focus is the smoke ...

Meanwhile, white smoke is produced using a much cleaner fuel mix and a more powerful oxidizer. Potassium chlorate (KClO₃)—even more reactive than perchlorate—ensures a hot, vigorous burn.

NASA officials ordered the removal of one of the massive rocket's RS-25 main engines after discovering a hydraulic leak on the engine's main oxidizer valve actuator, which controls the flow of ...

Sella says that although sodium perchlorate is a powerful oxidizer, it needs fuel to generate gaseous products that could cause an explosion like the one seen at the Iranian port. “Sodium ...

Hummel, Jr. "There was no extension of the fire into the building and damage was contained to the roof edge near the oxidizer ducking and the oxidizer itself. The cause of the fire was determined ...

The fire did not extend into the building, and damage was limited to the roof edge by the oxidizer ducking and the oxidizer. The fire started in the thermal oxidizer unit and was found to have ...

Editor’s note: Welcome to Just4Kids, a new feature with content from The Conversation for Kids, a nonprofit in which scholars answer kids’ questions about science, health and more, that will ...

In most rocket engines, liquid hydrogen fuel and liquid oxygen oxidizer are pumped into a combustion chamber, where they ignite and produce hot exhaust to propel the rocket. A plasma rocket ...

More specifically, the rocket propellant consists of both fuel and oxidizer. The fuel is typically something flammable, usually hydrogen, methane or kerosene. The oxidizer is usually liquid oxygen ...

This engine combusts its fuel and oxidizer in a rotating ring-shaped channel, and the resulting shockwaves create a sustained combustion reaction that makes the engine more efficient than ...
