unusual facts about protons



Similar

2,4-Dinitrophenol

It uncouples oxidative phosphorylation by carrying protons across the mitochondrial membrane, leading to a rapid consumption of energy without generation of ATP.

Brown adipose tissue

This energy is used to synthesize ATP when the protons flow across the membrane (down their concentration gradient) through the ATP synthase enzyme; this is known as chemiosmosis.

Cytochrome b

These complexes are involved in electron transport, pumping of protons to the create a PMF.

Deliming

The protons can then serve two functions, namely to protonate basic groups of the collagen and neutralize solution alkali chemicals.

Drip line

Nuclear drip line, the lines beyond which protons or neutrons leak out of nuclei

Faddeev equations

The Coulomb interaction between two protons is a special problem, in that its expansion in separable potentials does not converge, but this is handled by matching the Faddeev solutions to long range coulomb solutions, instead of to plane waves.

Geiger tube telescope

On Pioneer 11, one Geiger-Müller tube was replaced by a thin silicon wafer to detect protons in the specific energy range 0.61 to 3.41 MeV.

Gregory M. Garibian

Even at a very young age he followed news in the world of physics and was very excited when in 1942 he learned about the Alikhanian brothers’ expedition to Mount Aragats (Armenia) in order to search for protons in cosmic rays.

P-nuclei

In a p-process protons are added to stable or weakly radioactive atomic nuclei.

Protonophore

This would otherwise not occur as protons have positive charge and hydrophilic properties, making them unable to cross without a channel or transporter.

Quasiparticle

Motion in a solid is extremely complicated: Each electron and proton gets pushed and pulled (by Coulomb's law) by all the other electrons and protons in the solid (which may themselves be in motion).

Radiation treatment planning

For intensity modulated radiation therapy (IMRT), this process involves selecting the appropriate beam energy (photons, and perhaps protons), energy (e.g. 6 MV, 18 MV) and arrangements.
