5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug

Temperature range:
25°C~1500°C

Maximum 200°C/min
*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.

1. Introduction
Ammonia (NH3) is one of the most familiar compounds of nitrogen and hydrogen as well as one of the world's most valuable industrial and agricultural chemicals. Ammonia is used throughout the industrial world as a valuable fertilizer.
Ammonia and its compounds, primarily ammonium nitrate and other ammonium salts, replenish nitrogen in depleted soils. This greatly increases y

nanostructured materials
→ the charge storage from faradaic processes occurring at the surface of the material
→ the pseudo-capacitive effect, becomes increasingly important
mesostructured materials
→ enhanced oxidation and reduction kinetics
→ the relatively short diffusion path length for ions and electrons
kinetics and anisotropic growth. In the case of the first parameter, we observed that slowing the growth of the Au nanorods increases their aspect ratio. In other words, anisotropic growth can be facilitated at low temper- ature. Recently, it has been found that a range of ordered superstructures of particles can be obtained by similar self-assembly method. Murray and co-workers have develo- ped

kinetic energies. Some of the electrons will lose energy by inelastic scattering, which is primarily an interaction of the beam electron with an electron cloud of atoms in the sample. This inelastic scattering results in both a loss of energy and a change in momentum. These interactions may be phonon excitations, inter and intra band transitions, plasmon excitations or inner shell ionisations. Th
