Lanthanum–lithium–sodium double chromates as ionic conductors

open access: yesJournal of Alloys and Compounds, 1997
Lanthanum-lithium-sodium double chromates Li1-xNaxLa(CrO4)2 were prepared and analysed by means of admittance spectroscopy. Their a.c. conductivity parameters are correlated with structural details of high and low temperature forms of pure lanthanum ...

CHROMATIC CONTRAST∗

American journal of optometry and archives of American Academy of Optometry, 1970
ABSTRACT Chromatic contrast is of importance in contributing to the visibility of a colored object (10‐minute disc) on a colored background if the luminance contrast is very low. For luminance contrasts from zero to about 0.10.

Plasmid chromate resistance and chromate reduction

Plasmid, 1992
Compounds of hexavalent chromium (chromates and dichromates) are highly toxic. Plasmid genetic determinants for chromate resistance have been described in several bacterial genera, most notably in Pseudomonas. Resistance to chromate is associated with decreased chromate transport by the resistant cells.
