Examples of electron microscope in a Sentence

Recent Examples on the Web

The electron microscope revealed that the diamonds in the meteorite do house specific iron- and sulfur-bearing minerals that most likely formed at pressures greater than 20 gigapascals. National Geographic, "Diamonds From Outer Space Formed Inside a Long-Lost Planet," 17 Apr. 2018 This technique can illuminate structures too sensitive for normal electron microscopes. Avery Thompson, Popular Mechanics, "Scientists Get Their First Look at the Enzyme That Could Help Battle Aging," 27 Apr. 2018 The researchers looked at the meteorite through an electron microscope, finding traces of chromite, phosphate, and iron-nickle-sulfide inside the diamonds, minerals that only form under extreme pressure. Jason Daley, Smithsonian, "Diamonds Trapped in Strange Meteorite Came From Solar System’s Earliest Planets," 19 Apr. 2018 To confirm this, the Swagelok Center put our samples under an electron microscope, which nicely shows how densely packed the resulting mesh is. Lee Hutchinson, Ars Technica, "The Internet-demanded, partially scientific testing of Ultra-Ever Dry (in HD!)," 4 July 2018 As the name suggests, when viewed at a resolution of a few nanometres (billionths of a metre) through an electron microscope, the polymer strands look like tiny protruding bristles. The Economist, "Making medical clothing that kills bugs," 28 June 2018 Since the first electron microscopes turned their beams on bone in the late 1960s, scientists knew it was primarily made up of bone mineral and collagen, a fibrous protein. Angus Chen, Scientific American, "Core Strength: Extreme “Close Ups” May Help Explain Why Our Bones Are So Strong," 3 May 2018 In the above video, using a traditional electron microscope simply causes the dendrite to collapse from the high-energy beam of electrons. Avery Thompson, Popular Mechanics, "Researchers Take First Atomic Photos of Failing Battery," 27 Oct. 2017 To check on that explanation, a group led by Farhang Nabiei of the Swiss Federal Institute of Technology in Lausanne threw the diamonds under a transmission electron microscope. Scott K. Johnson, Ars Technica, "Meteorite’s diamonds tell of Earth’s baby sister, which died young," 18 Apr. 2018
