ABSTRACT: Quantum mechanics is one of the fundamental theories of physics which explains the nature of atoms and subatomic particles at least possible energy scale.In this mechanics, we solve physical problems by algebraic and analytic methods.The general solutions of Schrodinger's time - independent one dimensional equation for a particle restricted to move inside the infinite square well potential can be obtained by solving the Schrodinger's equation via matrix method. In this paper, we will discussthe Eigen energy values and Eigen functions of a particle restricted to move inside the infinite square well potential by solving Schrodinger's time- independent one dimensional equation by matrix method. We will conclude that the Eigen functionsobtained by solving the Schrodinger's time........

Key Words: Eigen functions, Eigen values, infinite square well, particle.

ABSTRACT: Vain attempts to unite gravitation with electromagnetism based on the relativity theory and quantum mechanics stimulates to search for alternative ways of their synthesis. It is shown that such an alternative may be realized if physics is constructed on the basis of energodynamics excluding hypotheses, postulates and model concepts to be used in the foundations of the theory. In such a case gravitation and electromagnetism are construed as different manifestations of the same interaction caused by the heterogeneous distribution of matter in space and the wave nature of matter and radiation. Experimental confirmations of the concept set forth are also made available in this article.

Keywords: methodological principles, relativity theory, quantum mechanics, gravitation, electromagnetism, radiation, field theory, modified laws

ABSTRACT: Sodium Copper Oxalate Na4Cd2 (C2O4) 4 4H2O (NaCuOx) single crystal was grown as transparent crystal using single diffusion silica gel technique. The triclinic and centrosymmetric nature of NaCuOx crystal structure with the P-1 space group was determined by the powder x-ray diffraction method. The functional groups were identified by FTIR spectroscopy. TGA of NaCuOx showed the formation of stable metal oxide at various temperatures due to the decomposition of ligand moieties. The projected optical parameters of the NaCuOx crystal were calculated by the UV-Vis-NIR and the highest absorption peak observed from the photo luminescence emission spectrum was used to explore the nonlinear optical efficiency of the as-grown crystal. The first attempt on antimicrobial activity of this crystal was carried at different concentrations (25, 50, 75 and 100 mg/ml) in-vitro against.............

ABSTRACT: A new semiorganic nonlinear optical material BisThioureasodium cadmium Chloride (BTSCC) has been synthesized. The solubility studies have been carried out in the temperature range 30- 55C. Single crystals of BTSCC have been grown by slow evaporation of saturated aqueous solution at room temperature. The structural parameters of the grown crystals have been determined by powder crystal X– ray diffraction technique. The UV-Vis-NIR transmittance spectrum has been recorded in the range 200 – 1400 nm. The secondharmonic generation has been confirmed by the Kurtz powder test.The FT-IR spectrum has been recorded in the range 400 – 4000 cm-1 and the spectral bandshave been compared with similar thiourea complexes.

Keywords: bisthioureasodium cadmium chloride, FT-IR, nonlinear optical material, SHG.
