Nanotechnology and Neutraceuticals

Neutraceuticals in Ayurveda with special reference to Avaleha Kalpana

The use of Neutraceuticals has drastically risen in recent years. Dr Stephan De Felice coined the term Neutraceuticals from "nutrition" and "pharmaceutical" in 1989. Related terms are "functional food" and "dietary supplement". In Ayurvedic pharmaceutics there are some secondary preparations like Avaleha Kalpana (Medicated semisolid preparation), Asavarista Kalpana (fermented preparation), Sneh...

Nanotechnology: opportunities and challenges

machines and process calculi The first model to capture the complex interplay between non-determinism and concurrency in distributed systems was Petri Nets [Pet], these nets were designed information flow in natural as well as man-made systems. In the early eighties, algebraic process calculi [BHR][Mil] were designed to model interactive systems hierarchically, and to model their behaviour abst...

Excitonic Crystal and Nanotechnology

The role and application of bound excitons in nanoscience and technology are discussed in this chapter. Bound excitons are well studied in semiconductors, especially in gallium phosphide doped by nitrogen (GaP:N). Doping of GaP with N leads to isoelectronic substitution of the host P atoms by N in its crystal lattice and to creation of the electron trap with a giant capture cross-section. There...

Nanotechnology and cancer.

The biological picture of cancer is rapidly advancing from models built from phenomenological descriptions to network models derived from systems biology, which can capture the evolving pathophysiology of the disease at the molecular level. The translation of this (still academic) picture into a clinically relevant framework can be enabling for the war on cancer, but it is a scientific and tech...
