One of the mysteries of the English language finally explained.
A unit of length equal to one hundred-millionth of a centimetre, 10⁻¹⁰ metre, used mainly to express wavelengths and interatomic distances.
- ‘Since an angstrom is a tenth of a millionth of a metre, that's pretty small.’
- ‘In the absence of a polymer cushion, the aqueous film thickness was found to vary between a few angstroms and more than 4 nm.’
- ‘An angstrom is an atomic scale unit of measure of one ten - billionth of a meter, approximately equaling the diameter of an atom.’
- ‘If one could stretch it out, a single DNA molecule can be more than a meter long (although only a few hundred angstroms wide)!’
- ‘The crystals, which resemble spheres just 50 angstroms wide, are engineered to hold and prevent lateral movement of a charge to other isolated nanocrystals.’
- ‘The rate of crack propagation in stage I is generally very low, on the order of angstroms per cycle, compared with crack propagation rates of microns per cycle for stage II.’
- ‘Some physicists like to use angstroms for wavelengths, while others use the strict metric system, so you will also find wavelengths given in nanometers.’
- ‘Dissecting out these small motions from thermal noise, already of amplitude a few angstroms, remains a challenge in simulation analysis.’
- ‘An angstrom is a unit of length equal to one ten billionth of a meter.’
- ‘An angstrom, a unit of length measuring the wavelength of light, is about 500,000 times smaller than the thickness of a human hair.’
- ‘The strength of the interactions involving the N-terminal residues increases between 2 and 4 ns, with an average decrease in the interside-chain distance of about an angstrom in all cases.’
- ‘We've been able to achieve a resolution of three angstroms - the width of three hydrogen atoms - in our measurements of the progress of this enzyme along DNA.’
- ‘Photonic crystal technology can create color screen displays 1,000 angstroms thick ideal for cell phones or new generation palm pilots.’
- ‘An angstrom, the smallest wavelength of light, is about 500,000 times smaller than the thickness of a human hair.’
- ‘While I'm thinking about it, did you know that last year an electron microscope was developed with a ‘resolution’ of 1 angstrom?’
- ‘Coatings that were once measured in microns are now measured in angstroms.’
- ‘The gramicidin channel consists of a head-to-head dimer of beta 6.5 helices in which the 4 - angstrom pore is lined by the neutrally terminated peptide backbone.’
- ‘Lipid molecules in large membranes are believed to assemble and move collectively as aggregates (so called ‘rafts’), which can span several hundred angstroms of the bilayer surface.’
- ‘The Mg 2 + cations were initially positioned several angstroms from the solute.’
- ‘The wavelength of radiation is sometimes given in units with which we are familiar, such as inches or centimeters, but for very small wavelengths, they are often given in angstroms.’
Late 19th century: named after A. J. Ångström (see Ångström, Anders Jonas).
