Definition of angstrom in English: angstrom(also Å, ångström, angstrom unit) nounˈaŋstrəmˈæŋstrəm A unit of length equal to one hundred-millionth of a centimetre, 10⁻¹⁰ metre, used mainly to express wavelengths and interatomic distances. 埃 Example sentencesExamples - The Mg 2 + cations were initially positioned several angstroms from the solute.
- The crystals, which resemble spheres just 50 angstroms wide, are engineered to hold and prevent lateral movement of a charge to other isolated nanocrystals.
- Since an angstrom is a tenth of a millionth of a metre, that's pretty small.
- 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.
- 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.
- An angstrom is a unit of length equal to one ten billionth of a meter.
- 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.
- While I'm thinking about it, did you know that last year an electron microscope was developed with a ‘resolution’ of 1 angstrom?
- An angstrom, the smallest wavelength of light, is about 500,000 times smaller than the thickness of a human hair.
- Photonic crystal technology can create color screen displays 1,000 angstroms thick ideal for cell phones or new generation palm pilots.
- 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.
- Coatings that were once measured in microns are now measured in angstroms.
- If one could stretch it out, a single DNA molecule can be more than a meter long (although only a few hundred angstroms wide)!
- 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 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.
- An angstrom is an atomic scale unit of measure of one ten - billionth of a meter, approximately equaling the diameter of an atom.
- In the absence of a polymer cushion, the aqueous film thickness was found to vary between a few angstroms and more than 4 nm.
- 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.
OriginLate 19th century: named after A. J. Ångström (see Ångström, Anders Jonas).
