Diamond aggregation

Diamond Aggregation

Internal diffusion-limited aggregation is a growth model based on random walk in Z. We study how the shape of the aggregate depends on the law of the underlying walk, focusing on a family of walks in Z for which the limiting shape is a diamond. Certain of these walks – those with a directional bias toward the origin – have at most logarithmic fluctuations around the limiting shape. This contras...

Rhombellanes are mathematical structures existing in various environments, in crystal or quasicrystal networks, or even in their homeomorphs, further possible becoming real molecules. Rhombellanes originate in the K2.3 complete bipartite graph, a tile found in the linear polymeric staffanes. In close analogy, a rod-like polymer derived from hexahydroxy-cyclohexane was imagined. Further, the ide...

Diamond and Polycrystalline Diamond for MEMSApplications :

To date most of the MEMS devices are been based on Silicon. This is due to the technological know-how accumulated on manipulating, machining, manufacturing of Silicon. However, only very few devices involve moving parts. This is because of the rapid wear arising from high friction in these Silicon based systems. Recent tribometric experiments carried out by Gardos on Silicon and polycrystalline...

Raman spectroscopy of diamond and doped diamond.

The optimization of diamond films as valuable engineering materials for a wide variety of applications has required the development of robust methods for their characterization. Of the many methods used, Raman microscopy is perhaps the most valuable because it provides readily distinguishable signatures of each of the different forms of carbon (e.g. diamond, graphite, buckyballs). In addition i...
