Significats de spinel en anglès

The floor was a mosaic of jacinth, spinel and sunstone.

Oxygen vacancies are formed and accumulate mainly around Ni ions until the layered-to-spinel phase transition begins.

A ring with a spinel ruby in it dropped out: she recognised the stone-itwas Miss Minerva's ring.

I'm sure it's a spinel.

Here, we study the evolution of size-dependent structure in spinel iron oxide and determine how nanoscale structure influences the growth of NCs.

As the size of the Ln increases, Mg mobility is found to increase, but stability in the spinel structure is found to decrease.

These excellent electrochemical properties are due to the fast kinetics of magnesium by the 2D nanosheets spinel structure and safe high-temperature operation environment.

A high cycling rate retards Li2MnO3 activation, leading to a smaller spinel phase transition and a higher cycling stability.

Furthermore, fast cycling rate was also found to help reduce possible structural changes from layered structure to spinel structure that takes place in continuous cycling.

They can tell lapis from sodalite and ruby from spinel more readily than I can distinguish amber from plastic or hematite beads from ball bearings.

There are, for example, certain red stones which the most skillful experts cannot by their color alone refer with certainty to ruby, garnet or spinel.

He is also lord of the mines of rubies, sapphires, and spinels.

Rubies, sapphires and spinels are found in Pegu.

They were true rubies, not spinels, remember that.

I think they're spinels.

From certain indications I judged these stones, which might have been spinels or carbuncles, or even rubies, to be very ancient.
