Metallurgical examinations revealed that the average grain size was 160 μm there.
The number of filter tap was appropriately chosen to assure the cutoff frequency was below that frequency.

The influence of nitrogen doping on the microstructure of N-ZnO includes crystalline grain size, strain and optical properties.
The number of patterns increases along with the addition of N doping, but there is a difference in the percentage of N8 that forms a ring-shaped colony.

The resulted grain surfaces have a porous microstructure.
Importantly, a number of pores, defects, and vacancies available on the activated carbon are expected to contain highly active sites supporting its adsorption property [14].

The nanorods synthesized in this study are not straight, with a number of the nanorods exhibiting noticeable curvature.
Such a growth mechanism would result in the formation of columnar structured films with all of the grains having the same crystal orientation (known as textured films).

For the same kind of grading, the bigger of the biggest nominal grain size, the bigger of asphalt mixture’s water permeability.
The number of measuring points in project 4 is 64, average rebound deflection value is 12.7(0.01mm), standard deviation is 3.76(0.01mm), represent deflection value is 20.2(0.01mm), while in project 7 the measuring points has 99, average rebound deflection value is 20.0(0.01mm), standard deviation is 3.67(0.01mm), represent deflection value is 27.4(0.01mm).

After heating, the grains softened and expanded to a size 10% to 60% larger than their original volume. 3.2.

Studies have shown that a number of improvements can be attained in such areas as machining efficiencies, material removal rate (MRR), and surface quality (SQ) using different types of powders.
Some of the powders that have been experimented upon include: Ni, Co, Fe, Al, Cr, Cu, Ti, C, Si and Mo, with grain sizes ranging between 1 and 100µm.
