Rubidium was chosen to investigate the unusual properties of extremely low-temperature fluids, known as Bose-Einstein condensates which have zero viscosity and the ability to spontaneously flow out of their containers. Their existence was predicted in 1925 by Einstein himself, who extended the work of Indian physicist S. N. Bose to suggest ...

by Ben September 8, 2020. Leave a Comment. Rubidium is a relatively benign element that typically parallels the potassium level. It varies according to levels found in water supplies. Rubidium is a non-toxic element and is known to be associated with lithium. It is also frequently found to be elevated with potassium.

Rubidium oscillators are the lowest priced members of the atomic oscillator family. They operate at 6,834,682,608 Hz, the resonance frequency of the rubidium atom (87 Rb), and use the rubidium frequency to control the frequency of a quartz oscillator. A microwave signal derived from the crystal oscillator is applied to the 87 Rb vapor within a cell, …

For correct peak identification, one needs to follow the rules below: i) The peak positions of EDS spectrometers should be calibrated accurately (see page1741 ). A miscalibrated system will shift X-ray peaks to improper energies, increasing the risk of misidentification. This is normally done by EDS manufacturers or by EM managers periodically.

Rubidium promoted iron Fischer–Tropsch synthesis (FTS) catalysts were prepared with two Rb/Fe atomic ratios (1.44/100 and 5/100) using rubidium nitrate and rubidium carbonate as rubidium precursors. Results of catalytic activity and deactivation studies in a CSTR revealed that rubidium promoted catalysts result in a steady …
