About Nanojoules
A nanojoule (nJ) is 10⁻⁹ J - the scale of ultrashort laser pulses, flash memory write operations, and cellular ATP reserves. A Ti:sapphire laser oscillator produces pulses of 1-20 nJ at 80 MHz. Flash NAND programming costs ~1-10 nJ/bit written; a read is ~0.1 nJ/bit. The total ATP energy stored in a single red blood cell is ~1-5 nJ. The kinetic energy of a 1 µg particle at 1.4 m/s is ~1 nJ, illustrating that nanojoules describe real nanoscale mechanical events. 1 nJ = 10⁻⁹ J.
About Femtojoules
A femtojoule (fJ) is 10⁻¹⁵ J - the scale of gamma-ray photons, molecular motor work, and state-of-the-art digital logic. The electron rest-mass energy is 81.87 fJ; a 100 keV X-ray photon carries 16.02 fJ. A single myosin II motor protein power stroke dissipates ~5-40 fJ. ATP hydrolysis under cellular conditions yields ~80-100 fJ of free energy. Advanced 3 nm CMOS gates switch at ~0.1-1 fJ per operation. Ultrafast fiber laser oscillators produce pulses of 0.1-10 fJ before amplification. 1 fJ = 10⁻¹⁵ J = 6.242 keV.
