Sintering and Characterization Studies of NiO
(EDP Sciences, 1986)
Des polycristaux de NiO de haute pureté ont été élaborés par frittage avec et sans charge. Ils ont été caractérisés par microscopie optique et électronique. Leur comportement en fluage a été étudié au dessus de 1200°C.

Multiple steady states on an adsorbent surface
(American Institute of Physics Publising LLC, 1986)
The occurrence of multiple steady states in a system formed by monomers adsorbed on a lattice, with attractive interaction between nearest adatoms, is demonstrated. This fact causes hysteresis in the adsorption-desorption ...
