Depending on the bath type and temperature, duration of the galvanising process, postgalvanising cooling methods, the type of steel, and surface preparation prior to galvanising, zinc coatings differ in terms of thickness, chemical composition, phase composition, morphology, crystallographic structure
of the surface, appearance, mechanical and corrosion properties, etc.
X-ray crystallographic structure
determination plays an important role in elucidation the mechanism of action of enzymes.
The crystal structure properties of natural and synthetic HAPs have been studied extensively because functions such as the solubility and bioactivity of synthetic materials are controlled by crystallographic structure
of these materials (Leventouri, 2006).
HA has been widely used as a bone substitute in restorative dental and orthopedic implants, due to its chemical and crystallographic structure
similar to bone mineral .

As 0 [less than or equal to] [delta] [less than or equal to] 0.04, the crystallographic structure
of LaMn[O.sub.3+[delta]] is orthorhombic structure (Pbmn, c/[square root of (2)] < a < b) and is strongly Jahn-Teller (JT) distorted; with the S increasing, the structure changes to the slightly JT distorted orthorhombic structure (Pbmn, a [less than or equal to] c/[square root of (2)] < b); when the [delta] > 0.1, it falls into the rhombohedral structure.
The available X-ray crystallographic structure
of PA complex with PB1 N-terminal fragment (amino acids 1-15) shows that, when bound to PA1, the secondary structure of 115 N-terminal fragment of PB1 is an alpha-helix .
XRD pattern of the as-prepared specimen shows that the hexagonal (a = 3.2459 [Angstrom], c = 5.1999 [Angstrom]) structure is the predominant crystallographic structure
according to the Cross-Ref PDF number 04-015-4060 card .
All water molecules and 3-bromo-7-nitroindazole (crystallographic ligand) were removed from the crystallographic structure
and all hydrogen atoms were added.
The chemical bond is thus one of the effective starting points in understanding the complex relationship between composition, crystallographic structure
and chemical and physical properties of solids.
