  • n. Symbol for technetium.

from The Century Dictionary and Cyclopedia

  • n. A symbol proposed by Von Behring to designate a curative principle derived from the tubercle bacillus. This substance is taken up by the cells of the body and there transformed into an integral part of these cells: in this form it is termed TX.

Examples

  • When a conventional superconductor reaches a critical temperature, called Tc, electrons begin to overcome their preference to mutually repel one another, and instead begin to bunch in pairs that like to cooperate with other pairs.

    The Register

  • The other role of a subcritical nuclear reactor or ADS is the destruction of heavy isotopes, particularly actinides but also longer-lived fission products such as Tc-99 and I-129.
