zeptojoule

plural zeptojoules

1. metrologyAn SI unit of energy equal to 10⁻²¹ joules. Symbol: zJ

   However, with zeptojoule scale switching energies and novel functionality, the BiSFET could add a substantial amount of road!

   When a bundle with a drag coefficient of 200 nN · sec · m⁻¹ (Howard and Hudspeth, 1988) produced a 25 nm, triangle-wave twitch 5 msec in total duration (Fig. 12A), the energy dissipated against viscous drag was ~100 zJ (a zeptojoule is 10⁻²¹ J).
