Correlated atomic motions in glassy selenium.
نویسندگان
چکیده
The elastic and total (energy-integrated) structure factors for glassy selenium have been measured by means of neutron spectroscopy within the temperature range 15 K& T & 310 K. The correlated nature of the atomic vibrations gives rise to marked features in the total (energy-integrated) inelastic structure factors defined as the difference between the total and elastic intensities. Also, both structure factors show rather distinct dependences with temperature, which are discussed in some detail.

Structural relaxation of glassy selenium under γ irradiation
2014 The effect of 03B3-rays on the structural relaxation of glassy selenium near the glass transition has been studied by dilatometry. We show that under irradiation the evolution time scale shifts about one decade. J. Physique LETTRES 42 (1981) L-501-L-502 . Classification Physics Abstracts 61.40D 64.70E 61.80E 15 NOVEMBRE 1981,

متن کاملCrossover of microscopic dynamics in metallic supercooled liquid observed by NMR.
Nuclear magnetic resonance is used to characterize local atomic motions in the glassy and supercooled liquid states of the bulk metallic glass system Pd43Ni10Cu27P20. The temperature dependence of the Knight shift reveals that certain local atomic motion decreases rapidly below a crossover temperature T(c) down to the glass transition temperature T(g). Above T(c) as well as below T(g) the mean-...
متن کاملConcanavalin A-bound selenoprotein in human serum analyzed by graphite furnace atomic absorption spectrometry.
We developed an assay for the direct determination of selenium in serum with a Perkin-Elmer Model 4100ZL Zeeman atomic absorption spectrometer and Ag-Cu-Mg modifier. We used this assay to analyze concanavalin A-bound selenoprotein (CABSP) in human serum after concanavalin A (ConA) affinity chromatography. The CABSP was identified as a single-chain glycoprotein of 57.3 kDa. Carbohydrate units we...
متن کاملThermal transport in glassy selenium: The role of low-frequency librations.
The experimental curves giving the temperature dependence of the thermal conductivity of glassy selenium are considered in detail. The observed behavior can be taken into account quantitatively if the densities of states for short-wavelength phonons as well as for low-energy librations arising from computer simulations are used for the calculations. In particular, it is shown that the lowestfre...
