The results indicated that the as-prepared nano-CuS showed a willow-like structure with average diameter of 30-40 nm.
TEM spectroscopy showed that nano-CuS had willow-like structure, the diameters of the majority of the particles fell into the range of 30-40 nm.
Otherwise, the nano-CuS solution only showed a broad and week peak at 439 nm, which confirmed the new structure were formed in solution.
TEM and UV-vis spectroscopy showed that nano-CuS had willow-like structure with proportional size distribution, which could be used in modified electrode.

This relatively new scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties.
It incorporates elements of applied physics and chemistry.
It is an important part of forensic engineering (Forensic engineering is the investigation of materials, products, structures or components that fail or do not operate or function as intended, causing personal injury or damage to property.) and failure analysis, the latter being the key to understanding, for example, the cause of various aviation accidents.

The overview for status quo of serpentine utilization consists of the distribution, chemical compositions, crystal structure of serpentine, mature but not economic applications and some development of high-value utilization research.
In the mineralogy, serpentine was taken as a ageneraldesignation of serpentine group minerals, which include: (1) the lizardite: plate-shaped structure layer, monoclinic system; (2) the chrysotile: tubular structure layer, monoclinic and orthorhombic system; (3) antigorite: wave-like structure layer, monoclinic system.

A larger particle size for DFO is expected due to its longer linear structure compared to the cyclic DOTA and NODAGA molecules.
In addition, the positive charge on the linear DFO structure, due to the many amines, could be interacting with other particles leading to association of the particles which can be detected by DLS.

The carbonate (CO32-) substitution into the HA structure has been found to reduce the degree of crystallinity and increases solubility in vitro as well as in vivo [14–16].
In total, according to XRD, DLS, and SEM analysis, all the synthesized BMHA powder consisted of agglomerated particles in the micrometer range made up of a huge number of crystallites in the nanometer range which created a porous structure.
According to published data in [34], the dissolution behavior of hydroxyapatite could be influenced by the structural and chemical compositions, the purity, defect formation, disordered structure, or the degree of porosities.

Ultra-fine Grained Fe-32%Ni Alloy Processed by Multi-axial Forging Baojun Han School of Chemistry and Life Science, GanNan Normal University, Ganzhou 341000, P.R.China hanbaojun80@tom.com Keywords: Fe-32%Ni Alloy, Severe Plastic Deformation, Grain Refinement, Multi-axial Forging Abstract.
The ultra-fine grained structure formation process was discussed in detail.
The banded structures were gradually broken up and evolved into cellular structures with widen boundaries as the cumulative strain increased up to 1.5, and the cellular structure boundaries consisted of tangles with a very high dislocation density (Fig.2b).
Firstly, the cellular structures with LABs were formed by the intersecting of deformation bands.
Firstly, they lead to the formation of the cellular structures by continuously subdividing the original grains; on the other hand, the decrease of cellular structure boundaries width is attributed to the rearrangement and the annihilation of dislocations with opposite Burgers vectors that accommodated in the cellular structure boundaries.

With as similar chemistry to cellulose, but different morphology, it is possible that starch may be used as renewable filler in rubber compounds.
Then swelling occurs, resulting in a mushroom-like structure appearing on the top of the starch surface (Figure 2c).
