BERKELEY, CA -- TEAM 0.5, the world's most powerful transmission electron microscope -- capable of producing images with half-angstrom resolution (half a ten-billionth of a meter), less than the ...

FLORENCE – A new laser ablation profile based on the modification of spherical aberration seems to effectively address presbyopia in a significant number of cases with no loss in quantity and quality ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

Lenses used in electron microscopy have aberrations that limit their resolution. Successful correction of spherical aberration is now possible, opening the door to three-dimensional, sub-ångström ...
