Bisphenol A (BPA), a high volume production chemical compound attracts growing attention as a health-relevant xenobiotic in humans. It can directly bind to hormone receptors, enzymes, and ion channels to become biologically active. In this study we show that BPA

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

Questions

1–2 of 2 Questions  

  1. Is the Barium packaged in oil or under a protective atmosphere?

    1 answer

    1. This product is packaged under Argon.

      Helpful?

  2. Hi, These Barium dendritics are grindable. I mean as a powder form to use as the precursor. Thank you Manasa

    1 answer

    1. The grinding of barium dendritic pieces into powder has not been attempted internally. A possible option would be to mill the barium dendritic or to shave it. However, based on the physical properties of barium, it may be difficult to grind to a powder.
      Please note that oxide will form in the presence of air.
