    is of the total weight of the material. It is one of the parameters used to characterise it. In the D 80 were used the particle sizes below which lie 10%, 50% and 90% by mass, or is, D 10 , D 50 and D 90 , respectively. Another parameter was not the coefficient uniformity (CNU). The higher the value, the greater the grain band and present highest rated is the material. Furthermore, when the non-coefficient uniformity is less than 2, it can be said that the material has a uniform particle size…

    which prevents corrosion by blocking oxygen diffusion to enter the passive layer and spreads rust into the internal material. As seen in Figure 1, stainless steel rather than forming a rust layer like other carbon steels, it produces an macroscopically invisible layer in which protects against rusting. [2] Figure 1: Stainless steel compared to other non-rust protection material Given that there…

    3.1.3 FESEM and EDS analysis The structural morphology of the Pure HA, Sr-doped HA, La-doped HA and La/Sr co-doped HA (different La concentrations of 0.03, 0.06 and 0.1M) nanoparticles are analyzed by FESEM images are shown in Fig. 3 (a)-(f). The morphology of pure HA shown in Fig 3 (a) indicates that formation of spherical (or) chain pearl shape of nanoparticles, ranging from 70 to 84nm. Further, Sr (0.1M) doped HA and La (0.1M) doped HA belongs to Fig.3 (b)-(c), appears the formations of few…

    The crystal size is also affected by the rate of cooling and larger crystals were shown to be formed when fat was cooled at a slower cooling rate83. However the samples were not subjected to changes in the rate of cooling in this study. At higher temperatures (or lower supercooling conditions) due to decrease in the driving force, less crystals are formed although the crystals are larger in size as compared to those formed at lower temperatures83. At lower temperatures, due to the higher driving…
