nanometer

Examples of nanometer in the following topics:

• X-Rays

  • X-rays are a form of electromagnetic radiation and have wavelengths in the range of 0.01 to 10 nanometers.
  • X-rays have wavelengths in the range of 0.01 to 10 nanometers, which corresponds to frequencies in the range of 30 petahertz to 30 exahertz (3·1016 Hz to 3·1019 Hz) and energies in the of range 100 eV to 100 keV .

• Damage to the Cell Wall

  • The cell wall of gram-negative bacteria is thin (approximately only 10 nanometers in thickness), and is typically comprised of only two to five layers of peptidoglycan, depending on the growth stage.
  • In gram-positive bacteria, the cell wall is much thicker (20 to 40 nanometers thick).

• Viral Size

  • Most viruses range in size from 5 to 300 nanometers (nm), although some Paramyxoviruses can be up to 14,000 nm long.

• Adherence

  • Fimbriae are fine filaments of protein, just 3–10 nanometers in diameter and up to several micrometers in length.
  • This appendage ranges from 3-10 nanometers in diameter and can be up to several micrometers long.

• Peptidoglycan Synthesis and Cell Division

  • The peptidoglycan layer is substantially thicker in Gram-positive bacteria (20 to 80 nanometers) than in Gram-negative bacteria (7 to 8 nanometers), with the attachment of the S-layer.

• Light

  • The wavelength of light is expressed in nanometers (nm); one nanometer is one billionth of a meter.

• Basement Membranes and Diseases

  • The electron-dense lamina densa membrane is about 30–70 nanometers in thickness, and consists of an underlying network of reticular collagen (type IV) fibrils (fibroblast precursors) which average 30 nanometers in diameter and 0.1–2 micrometers in thickness.

• X-Rays

  • X-rays are electromagnetic waves with wavelengths in the range of 0.01 to 10 nanometers and energies in the range of 100 eV to 100 keV.
  • X-rays are electromagnetic waves with wavelengths in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 100 keV .

• Gram-Negative Outer Membrane

  • The Gram-negative's cell wall is thinner (10 nanometers thick) and less compact than that of Gram-positive bacteria, but remains strong, tough, and elastic to give them shape and protect them against extreme environmental conditions .

• SI Unit Prefixes

  • Another older form of usage, the millimicron, is one thousandth of a micrometer, or 1 thousandth of 10-6 meters, or 10-9 meter, now called a nanometer.
