The First Measurement for Mass Attenuation Coefficients, Effective Atomic Numbers, and Electron Densities of Y123 and Y358 High-Temperature Superconductors (HTS) for the Energies from 46.6 to 1332keVHigh-Tc superconductorY123Y358Mass attenuation coefficient...
Atoms of an element are all the same in terms of shape and size and atoms of different elements differ in size and shape. Elements are characterised by mass of their atoms so all the atoms of an element have identical weight. Different elements have atoms of different atomic weight. Atoms ...
Following the discovery of electricity and the division of labor in the 1870s, machine structure and precision dramatically improved from the macro-to the micro size, enabling interchangeability and mass production. In the second half of the 20th century, the synergy of optics and light-induced ...
2) and first nearest-neighbor analysis (1NN, Supplementary Fig. 3). The mass-to-charge ratio of the ions recorded during the APT field evaporation process is displayed in Fig. 1e along with data recorded for undoped ErMnO3. The mass spectra are centered around ≈79.9 Da, where a ...
We first assessed spectral resolution in 2-dimensional amide nitrogen (15N) and proton (HN) (15N-1H HSQCSSMAS, Fig. 3a) correlation spectra, where different peaks reflect the different chemical environments experienced by the NH groups. Scalar couplings were used for magnetization transfer, as dip...
measures a force, the AFM can be used for various types of surfaces (unlike the STM), such as semiconductors, metals, and insulatingoxides. A landmark achievement of this technique was the first AFM image of the Si(111)-7×7 reconstruction. A comprehensive review of the evolution of AFM ...
It contains a short explanation of the effective mass tensor and how it is evaluated by the Recipe as well as a link to a relevant paper. The automatically generated part shows that the panel contains data generated by the asr.emasses Recipe. The two fields at the top of the page “...

4 Since the first glimpse about seventy years ago,5,6 NPCs have attracted increasing attentions from researchers. The NPC is the largest proteinaceous assembly in vivo, which consists of ~550–1000 molecules of ~30 different nucleoporins (Nups) with the molecular mass of 60–120 MDa from ...
It is the lightest element in the periodic table and the most abundant chemical substance in the Universe, constituting approximately 75% of all baryonic mass. The universal emergence of atomic hydrogen first occurred during the recombination epoch (Big Bang). At standard temperature and pressure, ...
