Order of morphological

Figure 4.1. Crystal faces with the highest rank in the order of morphological importance (with the highest reticular density) for P. F. and I lattice types of the cubic system (a) P lattice, 100) (b) F lattice. Ill) (c) I lattice. (110).

Figure 6.3. Expected difference in the features of growth banding in respective growth sectors depending on the order of morphological importance (MI, > MI >Ml3).A, B, and C indicate growth sectors corresponding to respective faces and the features to be observed in growth banding. The distribution of dislocations is not indicated.

Growth banding seen in different growth sectors will have different features depending on the order of morphological importance. This is due to environmental conditions. 

Figure 6.3 illustrates schematically features seen in the growth banding patterns in respective growth sectors, in relation to the order of morphological importance of the crystal faces. A rough interface disappears as growth proceeds, but the... 

The 111 face of diamond contains three PBCs, but 100 contains a maximum of two PBCs, even if surface reconstruction takes place. Therefore, the characteristics observed in CVD diamonds cannot be accounted for in terms of surface reconstruction due to the difference in solvents. If the surface energy term can be modified for any other reason, it is possible that the order of morphological importance maybe reversed. A possible reason maybe the surface adsorption of molecules on the surface of a growing CVD diamond. It has been calculated that molecules adsorbed on the surface can drastically modify the surface energy state of diamond. 

From the surface microtopographic characteristics summarized above, it is concluded that the order of morphological importance of p5U ite is 100 > 111 > 210. This order is in agreement with the results of PBC analysis. 

Resistance to antimicrobial agents is of concern as it is well known that bacterial resistance to antibiotics can develop. Many bacteria already derive some nonspecific resistance to biocides through morphological features such as thek cell wall. Bacterial populations present as part of a biofilm have achieved additional resistance owkig to the more complex and thicker nature of the biofilm. A system contaminated with a biofilm population can requke several orders of magnitude more chlorine to achieve control than unassociated bacteria of the same species. A second type of resistance is attributed to chemical deactivation of the biocide. This deactivation resistance to the strong oxidising biocides probably will not occur (27).
