Application
Barium can be used as a precursor to synthesize Ba3Bi6.67Se13,Ba3Bi6PbSe13, and Ba3Bi6SnSe13.
It can be used as a dopant for Pb2+replacement in perovskite films. The addition of barium enhances the power conversion efficiency of organic-inorganic lead halide solar cells.

Critical for the synthesis of pure Ba21M2O5HX (M = Ge, SI, Ga, In, Tl) suboxide Zintl phases.3
General description
Barium is a reactive, soft electropositive metal with a body-centered cubic crystal structure. It can be produced in a vacuum by reducing its oxide with aluminum. It has medium-specific weight and good electrical conductivity. It is widely used in alloying, removing unwanted gases from vacuum tubes, and as a reducing agent.

Interstitial cells of Cajal (ICC) generate slow waves in gastrointestinal (GI) muscles. Previous studies have suggested that slow wave generation and propagation depends on a voltage-dependent Ca(2+) entry mechanism with the signature of a T-type Ca(2+) conductance. We studied voltage-dependent

Early-life dietary transitions reflect fundamental aspects of primate evolution and are important determinants of health in contemporary human populations. Weaning is critical to developmental and reproductive rates; early weaning can have detrimental health effects but enables shorter inter-birth intervals, which
