Molecules are times smaller than 0.3 microns, they are measured in angstroms
. An angstrom
is one ten-billionth of a meter (3,000 A=0.3 microns).
Shahsavari's team modeled water molecules, which are about 3 angstroms
wide, inside carbon and boron nitride nanotubes of various chiralities (the angles of their atomic lattices) and between 8 and 12 angstroms
To improve that understanding, the next step for the researchers is to further boost the resolution of the images to about 3 or 4 Angstroms
. The team describes the work in the video below.
The determination of aTRP structure by cryo-EM "sent shockwaves through the field of structural biology," Cheng relates, as many researchers had dismissed the method as "blob-ology": until quite recently, cryo-EM's resolution--about 15 angstroms
at best--was far too coarse to discern the subtleties of structure in molecules as small as TRP ion channels.
In late March, the facility marked its first milestone with beam acceleration to 8GeV and spontaneous X-rays of 0.8 Angstroms
"Our drummer was into all technical things and he came up with Angstroms
," reveals Gordon.
Imation is addressing the challenge of building terabyte-class tape with its new Tera Angstrom
Technology, a proprietary metal particulate advanced formulation and manufacturing process to develop magnetic media that leads to uniform surface smoothness and higher SNR, and therefore enables the higher capacity and transfer rates required for future tape storage products.
ACRIMSat weighs 115 kilograms and carries a single instrument that measures the absolute solar flux from 2000 angstroms
in the ultraviolet to 20,000 angstroms
(2 microns) in the infrared.
NRL's new nanowriter is capable of defining patterns for electronic circuits with feature sizes on the order of about 80 angstroms
, (an angstrom
is a unit of length equal to one ten-billionth of a meter), according to G.M.
This video from NASA's Solar Dynamics Observatory shows the flare in a blend of two wavelengths of extreme ultraviolet light: 171 Angstroms
and 304 Angstroms
, colorized in yellow and red, respectively.
Coupled to any SBIG ST-7 or ST-8 camera, this slit- type, dual-grating spectrograph can capture spectra between 3800 and 7500 angstroms
with resolutions of either 2.2 or 8 angstroms
Brought no closer than about 200 angstroms
from a liquid's surface, the needle induces changes in the distribution of electric charge and orientation of the liquid's molecules, creating an attractive force.
The movie shows light at 304 Angstroms
and 171 Angstroms
, both of which help scientists observe the sun's atmosphere, or corona.
After some calculations, we settled on a pair of gratings yielding resolutions of about 5 and 10 angstroms
