• Microanalysis
  • The Microscopy Listserver is a network based discussion forum giving members of the scientific community a centralized Internet address to which questions/comments/answers in the various fields of Microscopy or Microanalysis can be rapidly distributed to a list of (subscribed) individuals by electronic mail. (wikipedia.org)
  • atomic
  • The researchers were able to figure out the total number and distribution of electrons in atomic energy levels that determine the local magnetic moments. (ecnmag.com)
  • EELS tends to work best at relatively low atomic numbers, where the excitation edges tend to be sharp, well-defined, and at experimentally accessible energy losses (the signal being very weak beyond about 3 keV energy loss). (wikipedia.org)
  • The research group was unaware of this publication until 1932, when they quickly realized that the De Broglie wavelength of electrons was many orders of magnitude smaller than that for light, theoretically allowing for imaging at atomic scales. (wikipedia.org)
  • phonon
  • However, due to the strong electron-phonon interaction in single-walled CNTs, it has been discovered that electronic current undergoes saturation at the voltage bias beyond 0.2 V. Nevertheless, CNTs with few nm in diameter are extremely robust compared with metallic nanowires of similar diameter and demonstrate conducting properties superior as compared with Cu. To make a connection, CNTs have to be paralleled in order to lower the resistance. (wikipedia.org)
  • inelastic electron
  • Non-fiction books Fundamentals of inelastic electron scattering. (wikipedia.org)
  • Dr. Leapman has devised new methods for quantifying both elemental and chemical information obtained from inelastic electron scattering, a research area in which he has over one hundred publications. (wikipedia.org)
  • electrostatic
  • Magnetic fields will act in a direction perpendicular to the electron propagation, thereby conserving velocity, whereas electrostatic fields will cause electrons to move along the field gradient, which may change electron energies if the component of the direction of propagation and field gradients are not perpendicular. (wikipedia.org)

  • Beside these activities, he was Honorary Professor at the Technical University of Berlin (1975-1995), Founding Editor of the Journal Ultramicroscopy with North-Holland Publishing Company (Elsevier), and Honorary Member in numerous international organizations about electron microscopy.

  • typically
  • There are several basic flavors of EELS, primarily classified by the geometry and by the kinetic energy of the incident electrons (typically measured in kiloelectron-volts, or keV). (wikipedia.org)
  • optics
  • Silicate glass is a metastable and durable solid that has application to a number of energy and environmental challenges (e.g., microelectronics, fiber optics, and nuclear waste storage). (osti.gov)
  • A position sensitive detector can detect the energy along one direction and depending on the additional optics lateral resolution or one angle along the other direction. (wikipedia.org)
  • LP-EM overcomes the key limitation of electron microscopy: since the electron optics requires a high vacuum, the sample must be stable in a vacuum environment. (wikipedia.org)
  • particle
  • H R {\displaystyle H_{R}} causes the particle to spiral through the lens, and this spiraling expose the electron to H Z {\displaystyle H_{Z}} which in turn focus the electron. (wikipedia.org)
  • biological
  • Leapman RD, Kocsis E, Zhang G, Talbot TL, Laquerriere P. Three-dimensional distributions of elements in biological samples by energy-filtered electron tomography. (wikipedia.org)
  • Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, metals, and crystals. (wikipedia.org)
  • image
  • As the ionisation signal is often significantly smaller than the background signal, it is normally necessary to obtain more than one image at varying energies to remove the background effect. (wikipedia.org)
  • He also initiated the development and designed the first user interface of DigitalMicrograph, which went on to become the world's leading electron microscopy image acquisition and processing software. (wikipedia.org)
  • Modern electron microscopes produce electron micrographs using specialized digital cameras and frame grabbers to capture the image. (wikipedia.org)
  • The spatial variation in this information (the "image") may be viewed by projecting the magnified electron image onto a fluorescent viewing screen coated with a phosphor or scintillator material such as zinc sulfide. (wikipedia.org)
  • techniques
  • A variety of microscopy techniques were used to characterized reacted grains and suggest the average altered layer thickness is 13.2 ± 8.3 μm with the hydrated and clay layer representing 74.8% and 25.2% of the total altered layer, respectively. (osti.gov)
  • The difference is mainly due to the difference in energy resolution between the two techniques (~1 eV or better for EELS, perhaps a few tens of eV for EDX). (wikipedia.org)
  • molecules
  • Adsorbate molecules adsorb readily because they lower the surface free-energy of the substrate and are stable due to the strong chemisorption of the "head groups. (wikipedia.org)
  • CNTs
  • Electron transport can go over long nanotube lengths, 1μm, enabling CNTs to carry very high currents (i.e. up to 109 Acm−2) with essentially no heating due to nearly 1D electronic structure. (wikipedia.org)
