Now from academic discipline point of view, there was no engineering science in the structure of discipline in early age.
Figure 3 Demonstrative Structures of Scientific Disciplines Hsue-Shen Tsien divided modern science and technology into eleven parts [8].
According to its distance to engineering, each part was classified to three levels as fundamental science such as physics, mechanics, chemistry, and as technical science such as applied mathematics, and as engineering technology such as gear technology.

The crystal planes of (220) and (311) are diffracted, so that the obtained silver wire has a face-centered cubic structure.
This is because the one-dimensional structure of the nano-silver wire makes it less than enough for the bacteria.

Copper was evenly distributed in the coating structure.
This is the result of the incorporation of electrocorundum particles into the structure of the coatings during sandblasting.

Zduinch et al [2] developed similar shape wings using carbon fiber pre-preg for vein structure and Mylar for membrane.
Placing sensor on such kind of structure will disrupt their properties.

The adhesive bonding of aluminum structures is widely practiced in aircraft, automotives and marine industries.
Underhill and Rider [3] reported that a porous hydrated oxide structure can be obtained on the aluminum alloy 2024 T3 and 7075 T6 when immersed in water temperatures as low as 40oC.

TEM images of SDS capped Cu NPs mounted on carbon coated Cu grids. 3.4 X-ray powdered diffraction (XRD) XRD analysis was performed to explore the structure and morphology of SDS capped Cu NPs.
Diffraction data inferred to the formation of pure crystalline phase Cu metal nanoparticles with face centered cubic (FCC) crystal structure having characteristic diffraction peaks at peaks (111), (200) and (220).The data obtained is in strong co-relation with previous reports concerning Cu nanoparticles [19, 20].

The main phase structures of the raw ore are SiO2 and FeOOH [6].
The solid phase structure was analyzed by X-ray Diffractionmeter, X’ Pert PRO MPD.

By incorporating specific additive known commonly as degradant additive, eco-degradant PD 04 used as additives for the process of degradation under the action of either UV, heat, oxygen, and/or mechanical shear will take place through formation of free radicals and there after leading to the chemistry of chain scissioning.

CdS-intercalated Bentonite: A Novel Sulfide Ion Selective Electrode Kemawadee Udomphan Atchana Wongchaisuwat Ladda Meesuk* Department of Chemistry, Faculty of Science Kasetsart University Bangkok 10900, Thailand.
CdS can be either cubic or hexagonal phases depending on the preparation method, surface properties studies indicated that cubic CdS nanoparticles presented a strong structural deformation but hexagonal reconstructed structures preserved their lattice behavior.
However, both cubic and hexagonal CdS nanoparticles structures were S-terminated [2].
