Otherwise in case of content of Mg 2+ ions are substituting Ca 2+ in the apatitic crystals lattice, the crystal's shape change and assume a globular form more similar to an amorphous structure, as demonstrated by all the analytical techniques described above.
It must be stressed that the degree of disorder observed for this sample does not correspond to a short range order, but to a true amorphous structure.

Emerging is a new monolithic Light Emitting Diode (LED) structure consisting of two layers which are doped with N and Al in the first layer and N and B in the second layer, as proposed by Kamiyama and coworkers at Meijo University, Japan.
The layers were grown using the sublimation epitaxy method [8] in which the sublimation of a solid source acts to feed the epilayer in a stacked structure with the substrate at top.

Recently, nanomaterials have drawn more attentions because of the functionalities unavailable to micron structured materials [4].

Solid state nuclear magnetic resonance (SS-NMR) spectroscopy was used to determine the presence and local environment of silicate groups within the HA structure.
This additional peak is likely due to the inclusion of silicon in the structure, resulting in two distinct P environments

Metal-catalyzed Synthesis of a Monomethine Cyanine Chengjun Wanga, Shanshan Gongb, Qi Sunc,* Jiangxi Key Laboratory of Organic Chemistry, Jiangxi Science and Technology Normal University 605 Fenglin Avenue, Nanchang, Jiangxi 330013, PR China aemail: wangchengjun_1989@163.com, bemail: gongshanshan33@gmail.com cemail: sunqi96@tsinghua.org.cn Keywords: Monomethine; Cyanine; Benzimidazole; ZrCl4; Catalysis Abstract.
Similar to the structures of other monomethine cyanines, compound 4 has two resonance structures and may become a potential fluorescent dye due to the existence of positive charge and conjugated alkene moieties in this molecule.

In order to improve the affinity of natural dye on hemp fibers, we can introduce additional amine and carboxyl group into the cellulosic structure using acrylamide as the modifying agent.
