The increasing of anode density also can prolong the utilization of anode in the condition of constant size which will reduce the replace number, and lessen effect of artifical action, and keep the balance of electric field and magnet field, and keep a reliable and efficient operation of aluminum electrolysis cell.
The batch formula of carbon anode consist of four grain size (5-8mm, 2-5mm, 1-2mm and powder).

As a result, the final phase composition of a silica material will be determined by
the type of raw material used, its grain size distribution, type of mineralizer as well as the course of
firing process.
In the conducted experiments the number of X-ray impulses reached the value of 70000 counts (Fig. 1 and 2).

Organelles were gathered around the cell wall and the number of chloroplasts reduced, equally the space between the cells became smaller.
The important changes of chloroplasts were that (1) chloroplasts became round, and were aggregated with different levels; (2) large vesicles were produced; (3) chloroplasts were broken; (4) grana were degraded, the stacking height of grana were reduced, broken chloroplasts were piled up together irregularly; (5) starch grains were aggregated.

Also in this experiment, molar ratio of S/Zn in precursor solution is 3, it is conducive to produce a large number of Zn vacancies.
It is due to ratio of surface and bulk phase atoms increase with the grain size decreased.

Triboluminescent Material With Shortwave Emission
ZnS-based materials as a function of grain size and dopants were long time used to typical triboluminescence investigations, and the triboluminescent emission from inorganic ZnS:Mn was considered to be an effective short wave luminescence material.

After the discovery of Carbon Nanotubes (CNTs) in 1991, the awareness in nanotechnology in the midst of the scientific community increased massively, this is evidenced by the number of articles published on CNTs [8-10].
Then the mixtures are fed into the hopper of the twin screw extruder and the wire form of the Nylon-CNT composite is obtained which is further subjected to a cutter to obtain the fine grains of the composite.
