abstract = {Barium salt of 12-tungstophosphoric acid (WPA) hydrate BaHPW 12 O 40 ·7H 2 O (BaHWPA·7H 2 O) has been investigated both in the microwave (X-band) region and in the lower frequency (5 Hz-500 kHz) region. This work is a continuation of our previous investigations on the influence of monovalent and bivalent cations on the dielectric properties of WPA hydrate salts. The real and imaginary parts of the permittivity (ε′, ε″) as a function of frequency and temperature, were determined in both frequency regions. The observed relaxations were attributed to specific relaxation processes. In the lower frequency range, the relaxation time τ=1.0×10 -6 s was assigned to barium ion jumps. In the microwave region, the dielectric relaxation time τ=1.7×10 -11 s was attributed to polyatomic ions (H 3 O + ) and/or H 2 O molecules reorientations. A phase transition was observed at 330 K. The low value of the activation energy for reorientation in the microwave frequency region is discussed. The d.c. conductivity and its temperature dependence were determined. Measurements were made in the temperature interval from 286 to 353 K. In the upper part of this temperature interval a PTCR effect was observed. © 2002 Published by Elsevier Science B.V.},

abstract = {In the present work the structural transformations of malvin in aqueous acetate buffer solutions were investigated over a wide pH range under in vitro conditions using electronic absorption spectroscopy. In addition to the spectroabsorptiometric investigation, the voltammetric behavior and the mechanism of the redox process of this molecule were studied, in order to define its antioxidant properties. The electronic absorption spectra reveal that the structural changes of malvin, caused by changes in the pH of the medium, lead to changes in the voltammetric behaviour of this molecule. The dependence of the oxidation potential of malvin on pH, which can be explained by the presence of different electroactive molecular structures of malvin at different pH values, indicates different mechanisms of the electrode process. The voltammetric activity of malvin is compared semiquantitatively with the voltammetric activity of a standard synthetic antioxidant, BHA, and a natural antioxidant, quercetin.},

In the oscillatory state, the phase response behavior corresponding to perturbations of different strengths is determined, and characterized by phase response curves (PRC and PTC).

Non-functionality of such structures is proved by AFM and atomic force spectroscopy experiments wherein the photochemical lignin functionalized tip is approached to the substrate covered with photochemical lignin. There was no evidence of existence of any kind of host-guest interaction during the approach/retraction experiments.

It is shown that with increasing integration time, the limits of detection are decreased within some limits and that the precision and concentration sensitivity are improved as well. A mathematical expression for the dependence of the detection limit on the integration time is presented. To increase the reliability of the measurement of the mentioned parameters, the working conditions were optimized for the following analytes: Ag, Al, Au, Cr, Fe, Mn, Ni, Pb, Pd, Pt, and V. The obtained limits of detection are comparable or better than those obtained by ICP for the elements studied. It was estimed that the possibility exists for their further improvement up to 10 times.},

The advantage of this method lies in the fact that it enables the simultaneous concentration of heavy metals, such as cadmium and lead, on cathode. The applicability of the method was illustrated by determining the arsenic content in some food samples based on vegetable oils and by comparing the results with those obtained by the classical technique of chemical hydriding with sodium tetrahydroborate.},

NMR and IR measurements have shown that the local silicon-aluminium ordering of the starting zeolite framework, as well as the framework fragments in the form of deformed tetrahedral rings, is retained in the glass structure. Interatomic distances and mean coordination numbers were calculated from the three-dimensional RMC derived structure model. The local Ba 2+ environment in the glass was compared with the corresponding crystalline polymorphs. Ba-O distances in the glass are longer than the distances in hexacelsian but the coordination number 12.00 and the increase in the Ba-T distance, compared to zeolite, indicate the establishment of hexacelsian-like coordination. Inspection of the three-dimensional RMC model of the glass showed a layered structure, with Ba 2+ cations between the layers.},

abstract = {The infrared spectra of the copigments of malvin with several organic acids: caffeic, ferulic, sinapic, chlorogenic, and tannic, were analyzed in order to elucidate the bonding of the molecules in the copigments. It was established that copigmentation is realized through hydrogen bonding between malvin molecules and the acids under study. The infrared spectra reveal that two groups of hydrogen bonds are formed, which include interactions of different molecular structures: hydroxy groups (bands around 3500 cm -1 ) and oxonium ions of the molecules (bands below 3000 cm -1 ). The formed hydrogen bonds were found to be of different strengths. The strengths of the hydrogen bonds were tentatively correlated with thermodynamic properties of the corresponding copigmentation reactions.},

This work is a continuation of our previous investigations on the influence of monovalent and bivalent cations on the dielectric properties of WPA hydrate salts. The real and imaginary parts of the permittivity (ε′, ε″) as a function of frequency and temperature, were determined in both frequency regions. The observed relaxations were attributed to specific relaxation processes. In the lower frequency range, the relaxation time τ=1.0×10 -6 s was assigned to barium ion jumps. In the microwave region, the dielectric relaxation time τ=1.7×10 -11 s was attributed to polyatomic ions (H 3 O + ) and/or H 2 O molecules reorientations. A phase transition was observed at 330 K. The low value of the activation energy for reorientation in the microwave frequency region is discussed. The d.c. conductivity and its temperature dependence were determined. Measurements were made in the temperature interval from 286 to 353 K. In the upper part of this temperature interval a PTCR effect was observed. © 2002 Published by Elsevier Science B.V.},

In addition to the spectroabsorptiometric investigation, the voltammetric behavior and the mechanism of the redox process of this molecule were studied, in order to define its antioxidant properties. The electronic absorption spectra reveal that the structural changes of malvin, caused by changes in the pH of the medium, lead to changes in the voltammetric behaviour of this molecule. The dependence of the oxidation potential of malvin on pH, which can be explained by the presence of different electroactive molecular structures of malvin at different pH values, indicates different mechanisms of the electrode process. The voltammetric activity of malvin is compared semiquantitatively with the voltammetric activity of a standard synthetic antioxidant, BHA, and a natural antioxidant, quercetin.},

A mathematical expression for the dependence of the detection limit on the integration time is presented. To increase the reliability of the measurement of the mentioned parameters, the working conditions were optimized for the following analytes: Ag, Al, Au, Cr, Fe, Mn, Ni, Pb, Pd, Pt, and V.

abstract = {Interaction between A1(III) and SCN - ion in aqueous solutions has been investigated using Raman spectroscopy. Eleven solutions with the SCN/A1(III) molar ratio from 0.5 to 10, have been studied. The systems of overlapped spectra in the v(CS) and v(CN) regions are analyzed by the methods of factor analysis. Spectra in the v(CN) and v(CS) regions have been reproduced using the first four and the first three vectors, respectively. The band areas in the v(CN) region have been determined by deconvolution and used for quantitative determination of species in solution. It is shown that the molar scattering coefficient of v(CN) is the same for all the species. The quantitative measurements of the Raman band intensity variation has revealed that Al(NCS)(H 2 O) 5 2+ , Al(NCS) 2 (H 2 O) 4 + and the two neutral, structurally different Al(NCS) 3 (H 2 O) 3 complexes are formed. The Al(NCS)(H 2 O) 5 2+ complex is present in the solutions with R ≤ 1, while the Al(NCS) 2 (H 2 O) 4 + appears in all the solutions with R ≥ 1. The neutral complexes are present for R > 4. In all the complexes, SCN - is coordinated through nitrogen as a terminal ligand. © 2001 Elsevier Science Ltd. All rights reserved.},

abstract = {The structure of stoichiometric celsian glass was investigated by 29 Si MAS NMR and IR spectroscopies and reverse Monte Carlo (RMC) simulation of X-ray diffraction data. The glass was prepared by thermally induced phase transformation of Ba 2+ -exchanged LTA (Linde Type A) zeolite, under annealing conditions prior to hexacelsian crystallization. NMR and IR measurements have shown that the local silicon-aluminium ordering of the starting zeolite framework, as well as the framework fragments in the form of deformed tetrahedral rings, is retained in the glass structure. Interatomic distances and mean coordination numbers were calculated from the three-dimensional RMC derived structure model. The local Ba 2+ environment in the glass was compared with the corresponding crystalline polymorphs. Ba-O distances in the glass are longer than the distances in hexacelsian but the coordination number 12.00 and the increase in the Ba-T distance, compared to zeolite, indicate the establishment of hexacelsian-like coordination. Inspection of the three-dimensional RMC model of the glass showed a layered structure, with Ba 2+ cations between the layers.},

abstract = {The infrared spectra of the copigments of malvin with several organic acids: caffeic, ferulic, sinapic, chlorogenic, and tannic, were analyzed in order to elucidate the bonding of the molecules in the copigments. It was established that copigmentation is realized through hydrogen bonding between malvin molecules and the acids under study. The infrared spectra reveal that two groups of hydrogen bonds are formed, which include interactions of different molecular structures: hydroxy groups (bands around 3500 cm -1 ) and oxonium ions of the molecules (bands below 3000 cm -1 ). The formed hydrogen bonds were found to be of different strengths. The strengths of the hydrogen bonds were tentatively correlated with thermodynamic properties of the corresponding copigmentation reactions.},

Infrared spectroscopy showed that the sorption of nitric oxides and ammonia does not destroy the crystal lattice of sepiolite, which was confirmed by XRD-analysis. Sorption of both nitric oxides and ammonia occurred by zeolitic water inside the structural channels of sepiolite.

For this purpose anodic stripping voltammetry with a rotating glassy carbon electrode was applied. A sufficient sensitivity on the presence of protein in solution containing Me-ions was obtained only by using a mercury dissolution signal (peak) observed at 0.1 V vs. SCE. Quantities of BSA less than 5 × 10 -7 M were determined with a S.D. ± 5% (n = 10) for a concentration of 3 × 10 -7 M, and for TF the concentration less than 1.5 × 10 -7 M could be determined with S.D. ± 4% (n = 10) for a concentration of 1 × 10 -7 M. © 2001 Elsevier Science B.V.},
