Polycrystalline CuInS2 thin films were grown by Spray pyrolysis method. This films have been deposited onto the glass substrate by varying substrate temperature from 275 0 C, at the interval of 25 to 350 0 C by using aqueous solution of Cupric chloride, Indium tri-chloride and thiourea of 0.02 M and Seems to be more important parameters affecting physical properties of the semiconductor. On account for the temperature dependent optical properties of polycrystalline CuInS2 thin films, grain boundary states were operative in nature. The values of absorption coefficient, extinction coefficient, refractive index, and dielectric constant have been calculated from the optical measurements. The prepared films at different substrate temperatures were found to have high transmittance (76 %) with the lowest thickness approximately t = 0.126 μm and at low transmittance (50 %) of the films with highest thickness nearly equal to t = 0.2163 μm. Due to temperature variation, the atoms are arrange regular in manner compound of CuInS2 films are investigates. As the films are not doped intentionally, defect observed in intrinsic nature by Sulphur interstitials. The most significant results in present study, the temperature varied with thickness of the film can be used to modify the optical band gap, extinction coefficient, refractive index and real-imaginary part of dielectric constants of CuInS2 thin films.

AbstractThe determination of the structure and properties of associated liquids could provide deeper insight into the phenomenon of the molecular interactions and is of great importance in biology and chemical physics. Dielectric constant measurements have been extensively used to obtain the electric dipole moment of molecules with the object of determining the polarities of their bonds, geometrical structures of the molecules and significant shifts of the electric charge in them. Dielectric parameters such as Kirkwood correlation factor, effective correlation factor, corrective correlation factor and thermo dynamical excess parameters for a mixture of diethyl phthalate with isobutanol and benzonitrile were determined at 303 k, 313 k and 323 k. The results were interpreted accordingly.

AbstractIn the present investigation, plant mediated bio-synthesis of copper oxide nanoparticles is synthesized using Manilkara hexandra leaf extract and were further characterized using Fourier transform infrared spectroscopy (Presence of biomolecules), UV-vis spectroscopy (250-300 nm), Field electron scanning electron microscope (30 to 60 nm), Energy dispersive x-ray analysis (Cu, O elements), X-ray diffraction analysis (face-centered cubic structure ), Particle size analyser (343 nm) , Zeta potential (-9.50mV). The Thermogravimetry/Differential Thermal Analysis and Differential scanning calorimetry is also examined to find the stability of materials. This confirms that copper oxide nanoparticles are well formed and synthesized. They are further tested with anti-microbial assays and antioxidant evaluation (DPPH method in-vitro) these reports show high estimation. This confirms that the copper oxide nanoparticles can be produced in large scale and can be implied for prevention of food , crops and drug delivery system.

Oral health could be maintained by application of this technology in prevention, diagnosis and treatment. Oral cancer is a debilitating disease, and numerous research activities are being pursued worldwide to combat this deleterious process. Nanotechnology is very diverse field that has revolutionized the industry and is setting new trends in the management of oral cancer. Hence, we performed a PubMed search on nanotechnology in oral cancer and found 211 articles related to this search. We have reviewed the reported literature to the best of our abilities and summarized the various aspects of nanotechnology, its role in diagnosis nanodiagnostics and treatment of oral cancer nanotherapeutics in this article. Nanotechnology for oral cancer could be a use full tool for detection and drug therapy. By Possessing unprecedented potential for early stage detection, treatment of oral cancer, nanoparticles have been demonstrated over the last decade. In this review, we will summarize the current state-of-the-art of nanoparticles in biomedical applications such as detection, diagnosis and targeting over the oral cancer. Gold nanospheres, nanorods, nanoshells, nanocages, and surface enhanced nanoparticles will be discussed in detail regarding their uses in vivo imaging, cancer therapy, and drug delivery. The key feature of nanoparticlebased drug agents to target over ligands, therapeutic drugs, and other functionalities can all be integrated to allow for targeted molecular imaging and molecular therapy of oral cancer. The future of the nanotechnology for oral cancer looks brighter than ever yet many hurdles remain to be conquered. A multifunctional platform based on gold nanoparticles, with multiple receptor targeting, multimodality imaging, and multiple therapeutic entities, holds the promise for a ―magic gold bullet‖ against oral cancer.
