However, although the predominant polymorph
is calcite, it seems that the sample grown at pH 4 contains some vaterite polymorph
since the small peaks located at 745.72 [cm.sup.-1] can be attributed to the out of plane bending vibrations of the vaterite polymorph
[18, 40, 41],
(2016) observed that the crystallization of [beta]L polymorph
in alcohol produced curved needle shape particles .
Although adjusting the fraction of exact exchange for a single polymorph
might not yield perfect agreement between experiment and theory for other phases, it represents a reasonable approach to study physical trends among the various polymorphs

As a matter of fact, a natural marine product, namely, the cockle (Anadara granosa) shell, has been widely reported to have good quality and pure calcium carbonate aragonite polymorph
content [1, 4, 7, 9, 10, 26].

The thermal effects on the polymorphs
of L-Glu have been an intriguing subject in solid-phase biochemistry.
Figure 5(a) (sample a) shows crystals of approximately 200 nm with oval morphology, corresponding to a polymorph
proportion of 49% B-51% A and Si/Al = 28, and Figure 5(b) (sample b) and Figure 5(c) (sample c) present crystals of around 400 nm and cuboid morphology with polymorph
proportion of 63% B-37% A and Si/Al ratios equal to 10 and 100, respectively.
The most amount of observed marker was in E11-M20 primer with a total of 20 polymorph
bands and E2-M17 and ETG-M35 primers with 19 polymorph
bands and the least amount was related to E46-M35, ETG-M22 and E8-M22 primers with 8, 8 and 9 polymorph
This is because the technique maintains the Polymorph
V content, the substance in the crystal structure of the fat which gives chocolate its glossy appearance and firm and snappy texture, but which also allows it to melt smoothly in the mouth.

V content, the substance in the crystal structure of the fat which gives chocolate its glossy appearance, firm and snappy texture but which also allows it to melt smoothly in the mouth.
The physical properties of the API -- such as crystal and salt form, polymorph
form -- have to be optimized.
