General description

Rubidium is a highly electropositive alkaline metal that can be obtained as a byproduct of refining lithium from lepidolite. It is used in photomultiplier tubes, laser cooling, atomic clock, photocell, nuclear medicine, and specialty glass.

Application

Rubidium can be used as a starting material to synthesize rubidium hydrazinidoborane (RbN2H3BH3).
It can also be used as a reducing agent to synthesize reduced polycyclic aromatic hydrocarbons.

By combining angle-resolved photoemission spectroscopy and scanning tunneling microscopy we reveal the structural and electronic properties of multilayer graphene on Ru(0001). We prove that large ethylene exposure allows the synthesis of two distinct phases of bilayer graphene with different properties.

Mutations that modulate the activity of ion channels are essential tools to understand the biophysical determinants that control their gating. Here, we reveal the conserved role played by a single amino acid position (TM2.6) located in the second transmembrane domain

Gastric H(+),K(+)-ATPase is responsible for gastric acid secretion. ATP-driven H(+) uptake into the stomach is efficiently accomplished by the exchange of an equal amount of K(+), resulting in a luminal pH close to 1. Because of the limited free energy
