We report the first direct study on the oxidation of carbon nanotubes at the resolution of an aberration-corrected environmental transmission electron microscope (ETEM), as we locate and identify ...

Abstract: Thermally-induced spherical aberration in Nd:YAG rods is investigated. Attention is concentrated on the so-called "intensity moment formalism" to analyze the beam-quality parameter of the ...

Wavefront aberrations introduce speckles in the telescope science images, which are patterns of diffracted starlight that can mimic the appearance of planets, complicating the detection of faint ...

These markers, however, do not reflect the effects of chronic exposure, including chromosomal aberrations that may herald genomic instability and predisposition to malignancy. Here we report important ...
