AB  - Cerium oxide (CeO 2-δ ) ultrafine nanoparticles, with the lower (CeO 2-δ -HT) and higher (CeO 2-δ -SS) fraction of oxygen vacancies, were used as anchoring sites for the polymerization of aniline in acidic medium. As a result, polyaniline-emeraldine salt (PANI-ES)-based composites (PANI-ES@CeO 2-δ -HT and PANI-ES@CeO 2-δ -SS) were obtained. The interaction between CeO 2-δ and PANI was examined by FTIR and Raman spectroscopy. The PANI polymerization is initiated via electrostatic interaction of anilinium cation and Cl − ions (adsorbed at the protonated hydroxyl groups of CeO 2-δ ), and proceeds with hydrogen and nitrogen interaction with oxide nanoparticles. Tailoring the oxygen vacancy population of oxide offers the possibility to control the type of PANI-cerium oxide interaction, and consequently structural, electrical, thermal, electronic and charge storage properties of composite. A high capacitance of synthesized materials, reaching ∼294 F g −1 (PANI-ES), ∼299 F g −1 (PANI-ES@CeO 2-δ -HT) and ∼314 F g −1 (PANI-ES@CeO 2-δ -SS), was measured in 1 M HCl, at a common scan rate of 20 mV s −1 . The high adhesion of PANI with cerium oxide prevents the oxide from its slow dissolution in 1MHCl thus providing the stability of this composite in an acidic solution. The rate of electrochemical oxidation of emeraldine salt into pernigraniline was also found to depend on CeO 2-δ characteristics. © 2019 Elsevier Ltd

AB  - In spite of extensive investigation and applications, influence of oxygen (O), and humidity on polyaniline (PANI) behaviour is not well understood. For this reason we have performed semi-empirical quantum mechanics, and ab-initio calculations of the pernigraniline base (PNB) PANI oligomers, of various lengths, before and after approach of H 2 O, O 2 , and hydroxyl (OH − ) group, and attachment of OH − and O to various molecular positions. Structure, charge and electrostatic potential distribution, relevant energies and enthalpies, infrared and electronic spectra of the PNB tetramer equilibrium conformation, and their changes induced by specific OH − , and O attachments are determined. These results provide identification of the most probable positions for O 2 and H 2 O approach to PNB_PANI, enthalpies of OH − and O attachments to them, changes of molecular properties induced by the attachments, and infrared and electronic modes that are most suitable for the attachments detection. The results are compared to the existing experimental data, and the results of similar calculations, and implications for the PNB_PANI applications are notified. © 2019 Elsevier B.V.

AB  - The ability of Bader's charge density topology analysis to explain various material properties has been examined for simple ionic systems of alkali halides and alkali hydrides. It was established that despite the fact that most of them share the same rock salt crystal structure phase, some of them belong to different topological classes. This fact was used to explain various experimentally observed properties of these materials, and to discuss their deviations from expected trends. Some phase transitions observed in these systems, and their possible relation to changes in the charge density topology have been also investigated from the same point of view. Reasons for anion-anion bond formation in some of them and its features are discussed, as well.

AB  - Structural and electronic properties, oxidation and aging effect of electrochemically (EC) synthesized magnetite nanopowders (NPs) are studied by means of X-ray diffraction (XRD), X-ray absorption fine structure (XAFS) and X-ray magnetic circular dichroism (XMCD). The obtained results enabled to get a direct insight into the structure and electronic properties of Fe immediate surrounding and to elucidate the influence of preparation conditions on stoichiometry of NPs and their stability in ambient conditions. All investigated NPs are produced as nonestoichiometric Fe3-delta O4 oxide phases, with the lattice constant and the Fe2+/Fe3+ ratio both in-between the values for bulk maghemite and magnetite. NPs synthesized under smaller current density (J = 200 mA/dm(2)) are more magnetite-alike, whereas larger current density (J = 1000 mA/dm(2)) has led to formation of NPs closer to maghemite. Oxidation of magnetite-like NPs is slower, although in the course of time particles agglomerate and oxide penetrates into the core. Maghemite-like NPs oxidize much faster and the oxide layer which is confined close to the particles surface protects the core from further oxidation. In all NPs the fist coordination around Fe is pretty stable against both temperature and oxidation process. The temperature change from 293 K to 20 K considerably affects the second coordination around Fe, which is most likely a consequence of the Verwey transition present in all investigated samples.

The samples were prepared by carbonization under N-2 atmosphere up to 850 degrees C, and activation in CO2 atmosphere at different both temperatures (750 and 850 degrees C) and times of activation (0.3,1 and 2 h). The influence of activation parameters on physicochemical properties was studied by XRPD, Raman spectroscopy, FTIR, N-2 physisorption, SEM and electrochemical methods.

AB  - Coating of nanoparticles by various molecules is promising way to modify their surfaces and extend their bio-functionality, and infrared (IR), and spectroscopy of electronic transitions at ultraviolet and visible (UV/VIS) wavelengths are suitable techniques to investigate details of their attachment at nanoparticle surface. In the present work structure and optical properties of dextran, chitosan, oleic acid and poly(ethylene glycol) have been investigated by semi-empirical quantum mechanics, and ab initio Hartree-Fock calculations using the HyperChem (R) software package (http://www.hyper.com). The equilibrium conformations, IR, and UV/VIS spectra of molecules of various lengths, before and after their attachment to the magnetite (111) surface are determined, and IR modes and UV/VIS transitions that change the most upon the molecules attachment identified. The results are compared to the existing experimental data and the results of similar calculations, and possible implications for biological applications of nanoparticles coated with the investigated molecules have been discussed.

In the present work structure and optical properties of dextran, chitosan, oleic acid and poly(ethylene glycol) have been investigated by semi-empirical quantum mechanics, and ab initio Hartree-Fock calculations using the HyperChem (R) software package (http://www.hyper.com). The equilibrium conformations, IR, and UV/VIS spectra of molecules of various lengths, before and after their attachment to the magnetite (111) surface are determined, and IR modes and UV/VIS transitions that change the most upon the molecules attachment identified. The results are compared to the existing experimental data and the results of similar calculations, and possible implications for biological applications of nanoparticles coated with the investigated molecules have been discussed.",

AB  - Local electronic and structural features around Mn in Cd1-xMnxTe0.97Se0.03 (x = 0.02; 0.05; 0.1; y = 0.03) were studied by means of X-ray Absorption Fine Structure (XAFS) techniques. Manganese ions with an average valence 2+, are found to be well incorporated into the host CdTe lattice, with clear preference for Te atoms as the first neighbors. However, Mn and Te are found to form two essentially different types of bonds, one short, strong and directional (cubic MnTe-alike bond), and three much longer, predominantly ionic in nature (hexagonal MnTe-alike bonds), thereby distorting the tetrahedral coordination around Mn. The origin of peculiar Mn Te bonds distribution and details of their nature and strength are further elaborated by employing the first principle electronic structure calculations. That way a thorough insight in impact of the Mn Te bond length variation on the electronic structure of the compound is obtained. The relations established between the local structures and electronic properties offer a reliable procedure for detailed analysis of the structural and electronic consequences of the 3d-transition metals (TM) incorporation in II-VI semiconductor host. Clear distinction between various influences makes the procedure easily adoptable also to the studies of TM impurities in other semiconductors. (C) 2015 Elsevier B.V. All rights reserved.

AB  - Electrochemical (EC) synthesis of magnetite (Fe3O4) nano-powders of specific characteristics is investigated in the range of current densities of J=200-1000 mA/dm(2), and temperatures of T=295-361 K. The obtained powders and their modification upon heating in air and argon atmosphere are examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmition electron microscopy (TEM), laser light scattering particle size distribution measurements, magnetic measurements by Faraday method and SQUID, and measurements of specific electrical resistivity. It has been established that structure, morphology, magnetic and electrical properties of the powders can be adjusted by using adequate EC synthesis conditions, and/or by their subsequent heating in the appropriate atmosphere. The temperature induced magnetite reordering, the magnetite to maghemite (gamma-Fe2O3), and the maghemite to haematite (alpha-Fe2O3) phase transitions were examined, too.
