The iron-neon hollow-cathode spectrum [PDF]
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1975 Over 4000 wave lengths are listed between 1900 and 9000 Å for Fe i, Fe ii, Ne i and Ne ii lines measured in a hollow cathode discharge tube with iron electrodes and a neon gas filling. Photoe-electric traces between 2400 and 5700 Å on a semiquantitative intensity scale are also included. For Fe i, energy values for 124 even and 240 odd levels have been

Hollow Cathode Discharges - Analytical Applications
Journal of Research of the National Bureau of Standards, 1984 The low pressure glow discharges considered in this paper are the hollow cathode (Paschen), and the flat cathode (Grimm). Both discharges have similar voltage-current characteristics which are responsible for their radiation stability. The analytical sample is supplied to the discharge through a sputtering mechanism which provides a stable and non ...

Reconstruction of Ultrafine MnS-Induced Vacancy-Rich Co<sub>9</sub>S<sub>6.29</sub> Precatalysts in Mesoporous S-Doped N-Rich Hollow Carbon Nanotubes Enables Dynamic O-Vacancy Cycling for High-Performance Zn-Air Batteries. [PDF]
Adv Sci (Weinh)We develop vacancy‐rich Co9S6.29 precatalysts formed via ultrafine MnS‐induced lattice distortion in mesoporous S‐doped N‐rich hollow carbon nanotubes (CM@SNHCTs). This CM@SNHCT precatalyst is reconstructed into catalytically‐active cathode phases that enable efficient oxygen reduction/evolution reactions (ORR/OER) through dynamic O‐vacancy formation ...
