After 30 days of storage at room temperature, PLA/ TBBC-25 exhibits the characteristic diffraction peaks located at 15.0, 16.5, and 18.9[degrees], corresponding to the planes (010), (200)/ (110), and (203)/(l 13) of orthorhombic crystalline phase [35, 36], Such peaks correspond to the typical a crystalline phase of PLA, which is described as pseudo-orthorhombic or orthorhombic unit cell.

The one peculiarity of Oklahoma's barite roses that makes them most resemble flowers is this: the "petals" of the rose, which consist of individual barite crystals, grew as round disks rather than adopting the tabular orthorhombic crystal forms that are normally present in barite (Fig.
In 1999, the structure of orthorhombic N, N'-diphenylguanidine (8) was reported as a "new crystal structure." LM reveals that this structure was previously reported in the literature in 1998 (9) (see Table 2).
The results also show that TNT in all crystalline states of four samples exist in monoclinic form which is considered to be more stable than orthorhombic form which is metastable at room temperature [16].
Two crystal structures have been reported for PLLA: an [alpha] crystal structure (pseudoorthorhombic, with a = 1.06 nm, b = 0.61 nm, c = 2.88 nm, and [alpha] = [beta] = [gamma] = 90[degrees]) with a -10/3 helical conformation [42, 43] and a structure (orthorhombic, with a = 1.031 nm, b= 1.821 nm, and c = 0.900 nm) with a -3/1 helical conformation [44], In Fig.
All of them are single phase, with orthorhombic structure (space group Pnma).
Upon calcination of the precursors at 900[degrees]C for 3h, the products with high diffraction intensity and better crystalline degree were readily indexed to be orthorhombic perovskite structured SrSn[O.sub.3] of the JCPDS database number 77-1798 [16].
Generally, ReMn[O.sub.3] has two kinds of multi ferroic structures, that is, hexagonal and orthorhombic. The rare earth ([Re.sup.3+]) ionicsize shrinks from 1.11 [Angstrom] to 0.94 [Angstrom] with decreasing the atomic number and reducing the electrons residing in the 4f orbit, called the lanthanum contraction effect.
