After the first crude X-ray diffraction images of DNA were collected in the 1930s, William Astbury had talked about stacks of nucleotides spaced at 3.4 angström (0.34 nanometre) intervals in DNA.
Higher integration Die of a PIC12C508 8-bit, fully static, EEPROM EPROM ROM -based CMOS microcontroller manufactured by Microchip Technology using a 1200 nanometre process.
Ionization here is due to Lyman series -alpha hydrogen radiation at a wavelength of 121.5 nanometre (nm) ionizing nitric oxide (NO).
It is usually expressed in picoseconds per ( nanometre · kilometre ).
The nanometre is also commonly used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum : visible light ranges from around 400 to 700 nm.
The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.1 nm, and that of a ribosome is about 20 nm.
