Rbcl lattice enthalpy
• Rubidium chloride is used as a gasoline additive to improve its octane number. • Rubidium chloride has been shown to modify coupling between circadian oscillators via reduced photaic input to the suprachiasmatic nuclei. The outcome is a more equalized circadian rhythm, even for stressed organisms.
