Abstract: Quantum-chemical calculations using the Density Functional Theory (DFT) approach for structural analysis of a new azo benzene derivative: Sodium 6-amino-5-hydroxy-3-((E)-(2-methoxy-4-((E)-(4-sulfonatophenyl)diazenyl)phenyl)diazenyl)naphthalene-2-sulfonate (A) (trans isomer) was designed using B3LYP method with 6-311++G** basis set. The electronic absorption spectrum of the A in water solution was calculated using TDB3LYP/6-311++G** method. The excitation energies, electronic transitions and oscillator strengths for studied structure have also been calculated. On the basis of calculations a new dichroic azobenzene dye A was synthesized. The experimental UV-Vis, FT-IR and 1H NMR spectra of the title molecule were presented. On the basis of polyvinyl alcohol (PVA) and the dichroic synthesized azobenzene dye A thermostable polarizing film absorbing in the seen region of the spectrum (λmax = 550nm) with Polarization Efficiency (PE) in the absorption maximum (λmax = 92%) and Stretching Degree (Rs) = 3.0 was developed. The experimental spectral-polarization parameters of stretched colored PVA-films were measured. During the work it was established that oriented PVA-films is phenomenon of anisotropy of thermal conductivity (λ‖/λ⊥). Thermal conductivity in a direction of orientation (λ‖) is higher than in a direction perpendicular orientations (λ⊥).

Abstract: Plastics production is increased recently due to their various applications such as construction, electronic, packaging and others. The rising in plastics demand lead to developed of recycling and energy recovery method to control plastic wastes. Recycling process is needs to be arranged according to resins, colors and transparency of all plastics. Energy dispersive X-ray fluorescence (EDXRF) was developed for the determination of the chemical composition in different plastics materials (with resin identification code) of PETE (1) or PET (01), HDPE (2) or PE-HD (02), V (3) or PVC (03), LDPE (4) or PE-LD, PP (5) or PP (06), PS (6) or PS (06) and Others (7) or O (07). XRF was measured elements such as Si, S, Cl, Fr, Ca, Ti, V, Fe, Cu, Zn, As, Kr, Zr, Nb, Mo and Nb in both kα and kβ lines, where PP with high percentage in both PET and PVC plastics, which is highly hazardous. In addition, chemical compositions in percentages were detected for various plastics materials.
