Table 1 Lattice parameters for Flabellina iodinea crystals and known
polymorphs of guanine Purified from Purified from Source F.
In order to reveal the
polymorph of grown CC crystals obtained in the presence of 1.0 g/L of PSDA-b-PEG solution in the crystallization reaction, XRD and FTIR-ATR were used.

Polymorph Identification and Composition Determination by XRD.
However, it is important to note that the monoclinic
polymorph is just more refined model structure of type (II) [La.sub.2][O.sub.2]C[O.sub.3] [18].
Nonetheless, calcium carbonate aragonite
polymorph recently emerges as one of the most popular targets among many scientists for profound exploration in many aspects, especially in the biomedical and pharmaceutical fields [1, 7-10, 20-22].
XRD analysis confirmed that calcite should be the dominant
polymorph of CaC[O.sub.3].
In nature, zinc sulfide generally occurs in the form of the cubic
polymorph sphalerite ([alpha]-ZnS), which crystallizes under a wide pressure-temperature range.
The
polymorphs of amino acids are ascribed to the complex interactions between the hydrogen bonding moieties (amino and carboxy groups) and side chains, which permit the steric and electrostatic interactions that specifically form the well-ordered aggregates in the solid phase.
The
polymorph CD64 should be used as a screening test for neonatal sepsis because of high sensitivity and a high negative predictive value.
