Abstract (PDF)
Graphical Abstract: Growth of the diffraction efficiency and recording velocity was found in the films of copolymers 4-((2- nitrophenyl) diazeniyl)phenylmethacrylate) with octylmethacrylate at room temperature holographic recording for copolymer with less softening temperature. Effect of strengthening of the diffraction efficiency was observed when charging surface of the films with recorded hologram in crown discharge.

Graphical Abstract: The feasibility of using Retama raetam, for the cationic dye (methylene blue) adsorption from simulated aqueous solution, has been investigated as a low cost and an eco-friendly adsorbent. The methylene blue maximum adsorption occurred at pH 8 and the lowest adsorption occurred at pH 2. The apparent equilibrium was reached after 120 min. Adsorption modelling parameters for Freundlich and Langmuir isotherms were determined and, based on R2, various error distribution functions.

Graphical Abstract: In this study, we have shown that FDDNP as a functional fluorescent biomarker has high performance in near-infrared region. The best predicted working wavelength belongs to Ti:sapphire laser (880 nm). The employed near-infrared (NIR) wavelengths reduce scattering and maximize tissue penetration.

Graphical Abstract: Geometry optimizations at the UBP86/6-311++G** level of electronic structure theory have been performed for DDT, β-hexachlorocyclohexane, and heptachlor organic polychlorides and their positive and negative ions. The geometry optimization of the obtained neutral intermediate molecules after the first and second reducing by two electrons show that the electrochemical dehalogenation of the organic poychlorides is sequential.

Graphical Abstract: It is shown that the only reason of structural distortions of ketene molecule coordinated in the complexes VCp2-H2C2O (I) and Pt(PPh3)2-H2C2O (II) is the pseudo Jahn-Teller effect induced by the orbital charge transfers by coordination. The η2-(C-O) coordination and the in-plane distortion of ketene in the complex (I) is due to the PJTE induced by the back donation to its LUMO 3b2. The η2-(C-C) coordination mode, and the out-of-plane distortion of the molecule in the complex (II) is caused by two OSTs: from the HOMO 2b1 to the metal, and from the dxy-AO of Pt to the vacant 3b1 MO of ketene, thus being the result of the diorbital Pt-ketene interaction.

Graphical Abstract: Planar organic heterostructures were prepared using poly-N- epoxypropylcarbazole films and poly[2-methoxy-5-(2’-ethylhexyloxy)-1,4-phenylenevinylene] by the method of successive deposition adding 2,3,9,10,16,17,23,24-zinc octabutylphthalocyanine. Photoelectric, photodielectric and photovoltaic properties of the heterostructures were studied.
