AMENDED CLAIMS

received by the International Bureau on 12 August 2013 (12.08.2013)

CLAIMS:

1. A room temperature process for the synthesis of carbon and carbon based nanocomposites comprising Laser-induced Dissociative Stitching (LDS) from liquid halogen containing aromatic compounds, comprising irradiating the liquid halogen containing aromatic compounds with an excimer laser source at room temperature and under non-inert conditions to obtain solid carbon and carbon based nanocomposite material, said excimer laser source selected from the group consisting of noble gas halide type such as XeCl(308nm), KrF(248nm) , ArF(193nm) which can generate significant light intensity in the narrow UV region, at frequency: 10 Hz, Energy Flux: 166.66 mJ/cm2 and time of irradiation in the range of 10-30 minutes.

2. The process according to claim 1, wherein the Laser-induced Dissociative Stitching process comprises layered, crystalline onion-like intermediates to obtain solid carbon and carbon based nanocomposite material.

3. The process according to claim 1, wherein the excimer laser source used is preferably KrF (248nm).

4. The process according to claim 1 , wherein the liquid halogen containing aromatic molecules are selected from the group consisting of chlorobenz ne, o-Dichloroberczene, bromobenzene, p-dichiorobenzene, biphenyl containing halogen.

5. The process according to claim 1, wherein the carbon based nanocomposites is prepared by in-situ irradiation of the liquid halo aromatics by including constituent materials or their precursors in the halogen containing aromatic systems wherein the carbon synthesized binds with the constituent materials to give corresponding carbon based nanocomposites

6. The process according to claim 1, wherein the constituent material is selected from polymers, inorganic compounds and other organic compounds.
