Aydil [17], who believe that FTO film on glass are highly textured with grains aligned preferentially in the (002) direction.
The result showed that the number of platelets adhering on as-prepared samples is obviously smaller than that on PU and glass (Fig. 6).
In addition, the statistical result revealed that the number of adhering platelets regularly increases with the decreasing of the nanorod diameter, indicating the scale of nanomorphology surface is an important factor to affect the blood compatibility.

Since the
number of manufacturing steps increases there is an increasing chance to reduce productivity and
yield.
A number of changes can occur throughout the material life cycle that reduces CO2 emissions [3].
It can be mentioned that both the yield strength and the tensile strength of the wire increase with an increase in the continuous casting speed result in an increase of grain boundary area and finer dendrite arm spacing.

In Fig. 1 (b) we plot the evolution of the fraction of martensitic phase Φm= Nm/N (with Nm the number of particles in the martensitic phase and N the total number of particles).
In all the snapshots, colored segments indicate the elongated side of each deformed triangle, and help to distinguish between grains of different orientation.

The required water /powder ratio is determined by conducting a number of trials [15,16].
Number of trail mixtures was tried for their permissible limits, and then the final proportions of ingredients and admixtures have been finalized for M20 Grade concrete with water cement ratio 0.4.

Now there are a large number of problems have to be solved, such as disposable forming, precise forming, reduce the residual stress, deformation, and avoid cracking and get the satisfactory microstructure, etc .
A large number of new technologies have been used for DLF, such as ultrasonic vibration and electromagnetic stirring to alter and reduce residual stress.
Experiment The experimental material is Ti-6Al-4V spherical powder, Grain size from-100 to 200 mesh and oxygen levels for 0.07% and the material composition is list at table 1.

A removable partial denture (RPD) represents the prosthetic solution for a partially edentulous patient who desires to have replacement teeth for functional and aesthetic reasons, and who cannot have a “bridge” (a fixed partial denture) for any number of reasons, such as a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or due to financial limitations.
So, in non-treated state (fig.2a) the structure consists in non-homogeneous molybdenum – chromium - cobalt solid solution and interdendritic eutectic, with very big grains.

DE clays have been widely used in drink water filtration as natural insecticide, grain protectant and immobilization of contaminants [11-14].This is attributed to the surface charge and natural pore size to the removal of cationic contaminants [15].
As the number of particles increases, the surface charge of all particles is greater, and therefore, these exhibit a strong interaction with the ion exchange capacity provided by the interstitial spaces of the DE.
Greater number Ag0 particles generate more surface charges, and therefore the interaction with the exchangeable cations available from the diatom is higher.

Some researches show that high cathode over potential is not only the prerequisites of promoting nucleation and inhibiting grain growth, but a key conditions of obtaining nano-crystalline.
When current density is overlarge, a large number of antimony particles will gather on the cathode and can’t be effectively coated by surface dispersants, resulting in the increasing of the particle size of antimony nanoparticles.

A large number of mutual connected crack appear from the C1# sheet; The C2# sheet has a good flexibility and lubricious surface while C3# sample has good film-forming performance, but has an un-even surfaces and it is difficult to demould.
It is shown that when sintered at 950°C, large number of µ-cordierite crystal phase and few amount of α-cordierite crystal phase are separated out of the cordierite sintered compact.
When the sinter temperature is 1000°C, viscous flow of liquid phase promotes the bond between particles polymerization, compel gas to remove along with the grain boundary and improve the density of cordierite sample.
