Carbon nanotube have unique structural, mechanical, electrical and chemical properties like high electrical conductivity, high specific surface area, good tensile strength. Facile functionalization paves way for promising applications in various fields like nanoscience, biosensors, drug delivery, scaffolds for tissue engineering, reproductive medicine, medical imaging and nanotechnology[2,3,4,5,6,7] . CNTs are cylinder shaped macro molecules with radius as small as few nanometers, which can be grown up to 20 cm in length[1]. CNTs are rolled up cylindrical tube of graphene sheets. The walls of these tubes are made up of a hexagonal lattice of carbon atoms analogous to the atomic planes of graphite. There are two types of carbon nanotubes, single-walled carbon nanotubes (SWCNT) and multi-walled carbon nanotubes (MWCNT). Single walled nanotubes (SWCNTs) consist of a single sheet of graphene rolled seamlessly to form a cylinder with diameter of order of 1 nm and length of up to centimeters. Multi-walled carbon nanotubes (MWCNTs) consist of an array of such cylinders formed concentrically and separated by 0.35 nm, similar to the basal plane separation in graphite. MWCNTs can have diameters from 2 to 100 nm and lengths of tens of microns[8]. The different structures of CNTs arises due to the different angle of folding of graphene sheet in a nanotube. The structure of the CNTs varies with

    3.1 Project Methodology In order to make sure that this project is on track, proper planning and scheduling is crucial. It is necessary to identify the significant key points which are photocatalytic activity of SWCNTs, properties of carbon nanotubes and titanium oxide, available testing procedures using scanning electron microscopy (SEM) and other spectroscopic methods. In this section, a brief detail provided regarding the methods used, sol-gel, hydrothermal and electrospinning. Also, the available tests that will be used are explained.

    All the fundamental vibrations are IR active stable structure. The harmonic vibrational frequencies calculated for doped fullerene with glycine have been compared from low frequency (below 1000 cm-1) to high vibrational frequency (above 1000cm-1) as shown in Table5. The symmetrical stretching vibrations of NH2 group are assigned in 3079, 3569 and 3613cm-1. The two strong stretching vibrations are found at 3569, 3695cm-1 for doped fullerene C19Si-glycine and 3569, 3715cm-1 for C19Ge-glycine. The strongest carbonyl stretching, vibration peak at 1769cm-1for doped fullerene interacting with amino acid C19Si-glycine and at 1780cm-1 for doped fullerene C19Ge-glycine peak are presented in Fig 7.

    The ganglia of neighboring segments are linked by connectives, while the hemi-ganglia are connected by commissures. Overall, the structure of this nervous system appears as a ladder-like chain consisting of a brain, two connectives, and a ventral nerve cord. Because lobsters lack a cerebral cortex, they rely on this complex nervous system to translate pain impulses into the sensation of pain

    Given the name endohedral fullerenes or endofullerenes, these trapped molecules have increased physical and electronic properties and open up a new world of applications in medicine, cosmetics and perhaps even superconductivity. There are two types of endohedral fullerenes in existence, which are endohedral metallofullerenes and non-metal doped fullerenes. Endohedral metallofullerenes are fullerenes that have been doped with electropositive metals through laser evaporation. These metallic atoms will transfer electrons to the surrounding cage and will also move off centre in the cage. There are usually 2 or 3 charge units in the fullerene cage, but this is difficult to determine accurately.

    Neurotransmitters are chemicals that pass the signals to other neurons in the body. Many neurons combine to form the spinal and cranial nerves. There are two main types of neurons: the sensory and the motor neurons. The sensory neurons carry information from the body, to the spinal cord and then to the brain. These neurons carry information that relates to the five senses (touch, pain, taste, etc.).

    This cell column is called the ciliospinal center of Budge. Once the fibers exit the spinal cord, they travel through the stellate ganglion, the inferior cervical ganglion, and the middle cervical ganglion to synapse in the superior cervical ganglion at the carotid artery bifurcation. From the bifurcation the fibers travel with the internal carotid artery, and then enter the cavernous sinus. From the cavernous sinus they travel along the abducens nerve. The fibers enter the orbit through the superior orbital fissure, and pass through the ciliary ganglion, without synapsing.
