The “Chromatic Octave” [PDF]

open access: yesNature, 1870
RENEWED attention to the “chromatic octave” tempts me to suggest an experiment. There used to be a gentleman, Smith, I believe, by name, who refuted the undulatory theory by means of a disc, divided into black and white sections, which he whirled with very high velocities, producing colours (so the Times positively stated) varying according to the ...

CONTRIBUTION TO THE STUDY OF THE PRECIPITATION OF CHROMATES

open access: yes, 1938
A study was made of the precipitation of the chromates of copper, cadmium, cobalt, zinc, and iron at room temperature. The concentration of the reacting metallic salt solutions was kept constant, and that of the potassium chromate solutions was varied ...

Rare Earth 3‐Hydroxyphenylacetate Complexes: Synthesis, Structural Characterization, and Surprising Improved Anticorrosion Performance on Mild Steel

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 27, 24 September 2026.
The rare earth (RE) aqua complexes using 3‐hydroxyphenylacetate ligand were prepared using the corresponding RE salt and the sodium salt of the ligand by a salt metathesis reaction. Two different structural motifs of the complexes, {[La(3hpa)3(H2O)] × 2H2O}n, and [RE(3hpa)3(H2O)]n (RE = Ce (2), Nd (3), Gd (4), Dy (5), Y (6), Er (7), Yb (8)) were ...

Effect of Oxygen and Nitrogen Oxide Gas Concentration on Corrosion of 310N Stainless Steel in Solar Salt at 600°C

open access: yesMaterials and Corrosion, Volume 77, Issue 9, Page 1579-1594, September 2026.
Schematic depicting corrosion layer formation and changes in stainless steel exposed to Solar Salt at 600°C for 1000 h under different atmospheres: (a) N2 accelerates salt decomposition, producing nitrite and oxide ions, causing severe corrosion. (b) Adding O2 reduces nitrite ions formation, resulting in less corrosion than N2 alone.

Zircon-monoclinic-scheelite transformation in nanocrystalline chromates

open access: yes, 2010
Our in-situ high-pressure X-ray diffraction measurements on zircon structured nanocrystalline chromates show that the structural phase transformation from zircon to scheelite phase proceeds via an intermediate monoclinic phase, i.e., zircon→monoclinic ...
