The mechanical properties change is highly affected by particle size and carbon black structure used.
Those mechanical changes are highly affected by the size, structure, surface activity, seed shape and amount (phr) of carbon black used.

Abstract.
The polycrystalline structure of the film can be observed through the X-ray diffraction(XRD)pattern., the characteristic peak of the(111),(200)and(220)crystal plane are observed at 2θ= 43.9°,50.9°and75.3°.
As can be seen from the fig.3 the diamond films synthesized are polycrystalline diamond films.In the XRD patterns of a diamond films, the peaks of (111), (200) and (220) of diamonds with cubic structure can be observed at 2θ= 43.9°, 50.9°and 75.3°,respectively.

This study first performed nanoscale bilayers assembly method, with the addition of top layer coatings for durability purposes, to modify the surface structure and thereby the hydrophilicity of the surface at 15, 17, 20, 23, and 25 bilayers.
Therefore, this study first performed nanoscale bilayers assembly method, with the addition of top layer coatings for durability purposes, to modify the surface structure and thereby the hydrophilicity of the surface at 15, 17, 20, 23, and 25 bilayers; we then empirically establish the relationship between the number of bilayers and the resulting contact angle.

Without any ultrasonic treatment, the structure contains dendrites of primary α-Mg phase which are coarser and non-uniform in size.
The mechanisms for microstructural refinement are discussed and it is concluded that the fine uniform grain structure achieved under ultrasonic vibrations is attributed to the cavitation and the acoustic flow induced by ultrasonic vibrations.

The X-ray crystal structure of the ERα was downloaded from the RCSB database (PDB ID: 3ERT).
BIOVIA Discovery Studio Visualizer 16.1 was used to remove the heteroatoms including water molecules present in the crystal structure.
The 2D chemical structure of the ligands was built using PerkinElmer ChemDraw software 16.0.

The classic design approach for MRF-based devices starts from the MRF formulation and is called “structure-to-rheology analysis”.
Recently an innovative design approach was introduced as opposite to the classic one, the “rheology-to-structure”[8] .

The article is devoted to the investigation of the efficiency of chromium-modified montmorillonite dispersions to stabilize the collagen structure of the dermis.
This tanning agent effectively forms the structure of dermis and provides the necessary physical and mechanical properties to the finished leather.
To evaluate the effectiveness of stabilization the collagen structure of the dermis, sheepskin after the pickling was used.
The larger mineral content of leathers under investigation is due to the presence of minerals in the structure of leather samples.

The influence of modifiers on the structure and properties of concrete was evaluated.
The structure: a – the structure of silicon production waste products; b – the structure of concrete without modifying additives; c – the structure of concrete with modifying additives Voids are formed both as a result of shrinkage and insufficient convergence of cement particles, when the amount of hydration products is insufficient to fill them.
This is due to the fact that hydration products have lamellar and scaly structures.
They influence the structure and properties of gray cast iron.

The peripheral part was fine crystal structure, but the size of the crystal grain became larger toward the outside.
The central part was fine crystal structure too, but it was surrounded by coarse columnar crystal region which represented as annular sunk region and separated the central fine crystal structure region from peripheral fine crystal region.
So theveryfirst touching part triggered nucleation at once, which grew and solidified rapidly, leading to form the central fine crystal part of solidification structure.
When the Si melt solidified at small undercooling degree nearby the equilibrium state and small cooling rate, octahedral structure will be formed due to the preferred orientation.

Hydrophobic interactions appear to be the single most important factor to stabilize protein structure, therefore making the protein more resistant to unfolding.
Addition of polymers or change of solvent has shown that enzyme stability can be increased by controlling precisely the nature and the structure of its microenvironment.
