A Low-voltage electron microscope (LVEM) is an electron microscope which operates at accelerating voltages of a few kiloelectronvolts (keV) or less. Traditional electron microscopes use accelerating voltages in the range of 10-1000 keV. Low voltage imaging in transmitted electrons is possible in many new scanning electron detectors.
A low-energy electron microscope used for surface science studies at University of Illinois' Frederick Seitz Materials Research Laboratory in Urbana, IL, USA. Low-energy electron microscopy, or LEEM, is an analytical surface science technique used to image atomically clean surfaces, atom-surface interactions, and thin (crystalline) films. [1]
CNET (short for "Computer Network") [1] is an American media website that publishes reviews, news, articles, blogs, podcasts, and videos on technology and consumer electronics globally.
With this new microscope, cellular details could for the first time be observed without using lethal stains. [1] By setting up some of the first time-lapse experiments with chicken fibroblasts and a phase-contrast microscope, Michael Abercrombie described the basis of our current understanding of cell migration in 1953.
