Ma Li et al[11] found that the lithium manganate with spinel-type cubic structure synthesized with the Mn2O3 prepared by manganese carbonate was fine-grained, dense, of uniform particles, and possessed excellent electrical properties.

Therefore, the cost, quality and availability of raw materials became of paramount importance and a significant number of companies are currently developing secondary manufacturing processes for their waste materials and by-products.
Fibers present the ability to act as a bridge between the grains of the mortar matrix.

The number of droplets is given on the y-axis, the natural logarithm of the radius (µm) on the x-axis.
Grain-like contrast features are due to surface damage.

.), the coating of Fe3O4 is composed by a number of rough grains.

Low solid solubility of Sn in aluminium matrix cause more Sn phases to be distributed at grain boundary and creates more defects on the oxide layer of aluminium.
Electrochemical impedance spectroscopy (EIS) has been increasingly employed by a number of investigators to study electrochemical properties of various materials [15-17].

The main style and Evolution law of the traditional Baina Textile The Chinese expression “Baina”, “Bai” is a classifier, referring to “a large number”, and “Na” meaning “patches”. [1] Just as its name implies, “Baina” meaning many patches and single pieces are integrated into a complete unit, which is practical and appreciating.
C: Because of its abundant color and grain, the traditional Chinese patchwork gives off a sense of peculiar and challenging, meanwhile, during the creation process, designers will get a feeling of infinite achievement from breakdown, rearrangement, and recreation.

The flattened grain shapes are typical for rolled steel.

Their size and shape depend on a large number of factors.

The thickness of the film affects as the film thickness increases, it influences the nucleation of WO3 grains [12].
The low-pressure O2 plasma process exhibits elevated energy per atom, leading to more bombardments on the WO3 surface and a greater number of surface defects [18].

It is notable that crystallinity of cellulose can be measured using a quite a number of methods such as Raman spectroscopy, infrared spectroscopy, differential scanning calorimetry (DSC) and solid state nuclear magnetic resonance (NMR).
XRD provides information on structures, phases, preferred crystal orientations (texture), and other structural parameters, which includes crystallinity, average grain size, strain, and also crystal defects [6].
