Rubidium-rich feldspars and associated minerals from the Luolamäki pegmatite, Somero, Finland [PDF]
Bulletin of the Geological Society of Finland, 1998 Rubidium feldspar occurs near the core zone of the highly fractionated petalite-subtype Luolamäki granitic pegmatite in intimate intergrowth with other feldspars which are part of a characteristic sequence of alteration of pollucite.

Collisional Redistribution Laser Cooling of a High Pressure Atomic Gas
, 2011 We describe measurements demonstrating laser cooling of an atomic gas by means of collisional redistribution of radiation. The experiment uses rubidium atoms in the presence of several hundred bar of argon buffer gas pressure.

Rubidium metaborate, Rb3B3O6 [PDF]
, 2004 Rubidium metaborate, Rb3B3O6, was obtained by the reaction of Rb2CO3 and BN using a radiofrequency furnace at a maximum reaction temperature of 1173 K. The crystal structure has been determined by single-crystal X-ray diffraction.

Rubidium doped nano-hydroxyapatite with cytocompatibility and antibacterial
Journal of Asian Ceramic Societies, 2021 Hydroxyapatite (HAp) is a widely used biomaterial because it is the main inorganic component of human bone and teeth. Rubidium (Rb) is a vital trace metal element in human body, and has been reported to possess antibacterial ability and can promote ...

Saturation of atomic transitions using sub-wavelength diameter tapered optical fibers in rubidium vapor [PDF]
, 2014 We experimentally investigate ultralow-power saturation of the rubidium D2 transitions using a tapered optical fiber (TOF) suspended in a warm Rb vapor. A direct comparison of power-dependent absorption measurements for the TOF system with those obtained
