Mass spectrometry, in particular, is a very powerful technique for the determination of the thermodynamic properties of condensed and gaseous phases at high temperatures. Ionov [56], Honig [57], and Chupka and Inghram [58,59] were pioneers in this field with their studies on the vaporization behavior of alkali metal halides and carbon at high

The direct experimental characterization of diffusion processes at nanoscale remains a challenge that could help elucidate processes in biology, medicine and technology. In this report, two experimental approaches were employed to visualize ion diffusion profiles at the orifices of nanopores (radius (ra) of 86 ± 6 nm) in array format: (1) electrochemically assisted formation of silica

Sb Concentration - an overview | ScienceDirect Topics

Figue 2 shows Sb depth profiles in Si for predeposition for 30 min and drive-in diffusions for 30 min in N 2, O 2, and wet O 2 (SIMS (A) and (C) in 1, respectively). After the drive-in diffusion, the surface concentration decreases dramatically in all atmosphere. In addition, the depths for O 2 and wet O 2 drive-in diffusions were shallower than the depth for predeposion diffusion.
