Assignment:
The title is " observational exercise on nanoscale size estimation"
Take a look atour javascript nanostructure explorerLinks to an external site. on a platform of your choice. Use this linkejavascript nanostructure-explorer linked here
(I need a report + images of the the work with an explanation of each step plus the calculation ) as well as "Specimen size and shape" andMagnification"
Assuming that the field width of the direct space images on the left are all 112.9 Angstroms, determine the physical magnification of the image on your device(s) or on printouts therefrom. This may require using a ruler. If you get the chance, try using this information to also estimate a characteristic dimension for each of the 7 unknown specimens (numbered 0 through 6) presently available. I'll set up a discussion board forum for you to discuss your findings.
Each time the page is loaded, both lens-setting and specimen-orientation are randomized, although a single focus-optimization will apply to all of the available specimens. Moreover the photos that you take as instrument operator are likely to be unique in detail, since each reload randomizes orientations modifiable only in one-degree increments. This is precise enough to characterize structures, but not to replicate images.
Cool specimens to play with might include:
• a silicon octahedron with {111} facets,
• a single hemoglobin molecule,
• a Si sphere with hemispheres twinned on (111),
• some single-walled carbon nanotubes to which Pt particles are attached with help from single-strand DNA,
• a group of randomly oriented nanocrystals,
• an insulating nanoparticle with the damage-trail of a fission-fragment's ion explosion-spike passing through it,
