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.

High-quality, large-area epitaxial graphene can be grown on metal surfaces, but its transport properties cannot be exploited because the electrical conduction is dominated by the substrate. Here we insulate epitaxial graphene on Ru(0001) by a stepwise intercalation of silicon and

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

Restricted target accessibility and surface-induced perturbation of the aptamer structure are the main limitations in single-stranded DNA aptamer-based electrochemical sensors. Chemical labeling of the aptamer with a probe at the end of aptamer is inefficient and time-consuming. In this work

Hydration structure and polarization of Rb(+) and Cs(+) in liquid water at ambient conditions were studied by first principles molecular dynamics. Our systematic analysis of the relevant electronic structures, based on maximally localized Wannier functions, revealed that the dipole moment

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.
