ABSTRACT: Detailed analysis of the interfacial behavior of water and weakly polar or nonpolar organics adsorbed alone or co-adsorbed onto activated carbons (AC) at different temperatures is a complex problem important for practical applications of adsorbents. Interaction of water, 1-decanol, and n-decane with AC possessing highly developed porosity (pore volume Vp≈1.4-2.3cm(3)/g, specific surface area SBET≈1500-3500m(2)/g) was studied over a broad temperature range using differential scanning calorimetry (DSC), thermoporometry, (1)H NMR spectroscopy, cryoporometry, and temperature-programmed desorption with mass-spectrometry control methods. Comparison of the pore size distributions (PSD) calculated using the DSC thermoporometry, NMR cryoporometry, and nitrogen adsorption isotherms allows us to determine localization of adsorbates in different pores, as well as changes in the PSD of AC due to freezing of adsorbates in pores. Theoretical calculations (using ab initio HF/6-31G(d,p), DFT B3LYP/6-31G(d,p), and PM7 methods) explain certain aspects of the interfacial behavior of water, decane, and decanol adsorbed onto AC that appear in the experimental data. Obtained results show strong temperature dependence (above and below the freezing point, Tf, of bulk liquids) of the interfacial behavior of adsorbates on the textural characteristics and hydrophilic/hydrophobic properties of AC and the adsorbate amounts that affect the distributions of adsorbates unfrozen at T<Tf in pores of different sizes.Journal of Colloid and Interface Science 05/2013; · 3.07 Impact Factor -
Article: Interfacial behavior of silicone oils interacting with nanosilica and silica gels.
[show abstract] [hide abstract]
ABSTRACT: The interfacial behavior of silicone oils Oxane 1000 and Oxane 5700 (polydimethylsiloxanes, PDMS) interacting with dried or hydrated (hydration h=0.005 or 0.1g/g) silica gels Si-60 and Si-100 or nanosilica A-400 was studied using low-temperature (1)H NMR spectroscopy over the 210-310K range. Broadening of the melting temperature range toward both sides from the freezing point is observed for silicone oils confined in mesopores (2-15nm in radius) of silica gel particles (0.2-0.5mm in size) or voids (1-100nm) between silica nanoparticles (5-10nm in size) in their aggregates. This effect is a consequence of the phase state heterogeneity, since both liquid and solid-like fractions of adsorbed PDMS are observed over a large temperature range. The adsorbed PDMS heterogeneity depends on the pore size distribution (confined space effect), and it is lower for silica gel Si-100 possessing broader pores than Si-60. An increase in the amounts of adsorbed polymer and water diminishes the effects of confined space on PDMS because a fraction of the polymers is located in broader pores or out of pores (voids). This leads to relative decrease in interactions of PDMS with the silica surface. (1)H NMR spectra of PDMS and n-decane bound to silica gels reveal much stronger heterogenization of adsorbed PDMS (depending on the polymer length) than that of the alkane.Journal of Colloid and Interface Science 12/2012; · 3.07 Impact Factor -
Article: Heating effects on morphological and textural characteristics of individual and composite nanooxides
[show abstract] [hide abstract]
ABSTRACT: Morphological, structural and adsorption characteristics of nanooxides (fumed individual silica, alumina and titania, and composite silica/alumina, silica/titania and alumina/silica/titania) were compared after different treatments (wetting/drying, ball-milling, suspending/drying, heating) at different temperatures (373–1173K) using low-temperature nitrogen adsorption data. The structural characteristics such as specific surface area (S BET), pore volume (V p), pore (PSD) and particle (PaSD) size distributions (calculated using self-consisting regularization procedure with respect to both PSD and PaSD), fractality, adsorption energy distributions depend differently on heating temperature because desorption of water molecularly and dissociatively adsorbed at a surface and in bulk of primary nanoparticles occurs over a wide temperature range at different rates. These processes affect both structural and energetic characteristics of nanooxides.Adsorption 04/2012; 15(2):89-98. · 2.00 Impact Factor -
Article: Influence of mechanochemical activation on structure and some properties of mixed vanadium–molybdenum oxides
[show abstract] [hide abstract]
ABSTRACT: Mechanochemical activation of individual V2O5, MoO3 and mixed vanadium-molybdenum oxide system in various media (air, water, and ethanol) has been studied. Powder X-ray diffraction, nitrogen adsorption–desorption, thermogravimetric and chemical analysis, FTIR and Raman spectroscopy, and scanning electron microscopy have been used for research of prepared milled samples. The electrokinetic properties (dependence zeta potential—pH, position of isoelectric point) of individual V2O5, MoO3 and mixed vanadium–molybdenum oxide system, synthesized via mechanochemical treatment in various medium, in aqueous solutions of electrolytes also have been determined. Initial, milled, and spent samples are characterized with the help of XRD, FTIR and Raman spectroscopy, and SEM and adsorption of nitrogen. The catalytic properties of vanadium–molybdenum oxide composition activated in different media have been investigated in reaction of oxidation dehydrogenation of propane.

Article: Structural, textural and adsorption characteristics of nanosilica mechanochemically activated in different media.
[show abstract] [hide abstract]
ABSTRACT: The structural, textural, and adsorption characteristics of mechanochemically activated (MCA) fumed silica A-300 as dry or water, ethanol, or water/ethanol-wetted powders (0.5 g of a solvent per gram of silica) in a ball mill for 1-6 h were studied in comparison with those of the initial powder. The MCA treatment enhances bulk density (ρ(b)) of the powder (from 0.045 g/cm(3) for the initial silica to 0.4 g/cm(3) for 6 h-MCA-treated water-wetted silica) depending on medium type and MCA time (t(MCA)). Stronger effects are observed for the MCA treatment of water-wetted silica than of dry or ethanol- or water/ethanol-wetted samples. The MCA treatment weakly affects the specific surface area (S(BET)). However, void (pore) size distribution, porosity, particle aggregation and size distribution in aqueous suspension, behavior of interfacial water, properties of poly(vinyl alcohol)/silica composites and adsorption of gelatin depend more strongly on the t(MCA) and ρ(b) values. Some of the observed changes in the characteristics (e.g., gelatin adsorption) depend on the ρ(b) value but are independent of the medium type used on the MCA. Other characteristics are nonlinear functions of both t(MCA) and ρ(b) values.Journal of Colloid and Interface Science 03/2011; 355(2):300-11. · 3.07 Impact Factor -
Article: Adsorption of polar and nonpolar compounds onto complex nanooxides with silica, alumina, and titania.
[show abstract] [hide abstract]
ABSTRACT: Adsorption of low-molecular adsorbates (nonpolar hexane, nitrogen, weakly polar acetonitrile, and polar diethylamine, triethylamine, and water) onto individual (silica, alumina, titania), binary (silica/alumina (SA), silica/titania (ST)), and ternary (alumina/silica/titania, AST) fumed oxides was studied to analyse the effects of morphology and surface composition of the materials. Certain aspects of the interfacial phenomena dependent on the structural characteristics of oxides were analysed using calorimetry, (1)H NMR, and Raman spectroscopies, XRD, and ab initio quantum-chemical calculations. The specific surface area S(BET,X)-to-S(BET,N(2)) ratio (X is an organic adsorbate) changes from 0.68 for hexane adsorbed onto amorphous SA8 (degassed at 200 degrees C) to 1.85 for acetonitrile adsorbed onto crystalline alumina (degassed at 900 degrees C). These changes are relatively large because of variations in orientation, lateral interactions, and adsorption compressing of molecules adsorbed onto oxide surfaces. Larger S(BET,X)/S(BET,N(2)) values are observed for mixed oxides with higher crystallinity of titania or/and alumina phases in larger primary nanoparticles with greater surface roughness and hydrophilicity. Polar adsorbates can change the structure of aggregates of oxide nanoparticles that can, in turn, affect the results of adsorption measurements.Journal of Colloid and Interface Science 08/2010; 348(2):546-58. · 3.07 Impact Factor -

ABSTRACT: Morphological, structural, electronic, and adsorption characteristics of complex oxides such as fumed silica/alumina and silica/titania, fumed silica with deposited oxides of Mg, Ti, Mn, Ni, Cu, Zn and Zr, silica gel with grafted ZrO2, sol–gel titania doped by 3d-metals (Cr, Fe, Mn, V) were compared using adsorption, TEM, AFM, XRD, XPS, Mössbauer and Raman spectroscopy data. It was shown that surface, volume, and phase compositions of oxides, particle size distributions (5 nm–3 μm), specific surface area (SBET ∼ 50–500 m2/g), and porosity (VP ∼ 0.1–2 cm3/g) affected by synthesis technique and subsequent treatment determine electronic structure (bandgap, valence band and core levels structure) of the materials, adsorption of molecules and metal ions as well as other characteristics.Applied Surface Science 01/2010; 256:5263-5269. · 2.10 Impact Factor -
Chapter: Regularities in the Behaviour of Nanooxides in Different Media Affected by Surface Structure and Morphology of Particles
[show abstract] [hide abstract]
ABSTRACT: Textural and adsorptive characteristics, surface structures, and the volume of individual, binary and ternary nanooxide particles with SiO2, Al2O3 and TiO2 were investigated. These materials’ interactions with low and high molecular weight compounds were investigated using adsorption, NMR, TSDC, DRS, FTIR, TPD–MS, Auger spectroscopy, optical spectroscopy, DLS, titration and microcalorimetry. The presence of a structural hierarchy of particles from primary (10–50nm), their aggregates (50–1000nm) and agglomerates of aggregates (> 1μm) to visible flocculi affects textural features of the oxides, adsorption of different compounds and the behaviour of materials in liquid media.12/2009: pages 93-115; -
Chapter: Self-Organization of Water–Organic Systems in Bone Tissue and Products of Its Chemical Degradation
[show abstract] [hide abstract]
ABSTRACT: Hydration of bone tissue and products of its thermal and chemical degradation in the presence of organic solvents was studied using low-temperature 1H NMR spectroscopy and cryoporometry. It was revealed that water filling nanosized cavities between structural elements of bone tissue can be assigned to two types of clustered structures corresponding to strongly and weakly associated water reflecting in the 1H NMR spectra as separate signals with chemical shift δ H = 1.3 and 5ppm. It was shown that the chloroform medium stabilizes weakly associated water and reduces interaction of strongly associated water with the phase boundaries. The same tendency is outlined in protein and mineral components of bovine bone. The presence of electron-donor solvents (acetonitrile, DMSO) leads to formation of clustered structures (with electron-donor molecules, strongly associated water or water solution in organic solvents) in the hydrate shells of structural elements of bone materials. In contrast to the native bone material, individual model systems with proteins or mineral components are characterized by a considerable diminution or complete disappearance of weakly associated water.12/2009: pages 79-92; -

[show abstract] [hide abstract]
ABSTRACT: Fe2O3/SiO2 nanocomposites based on fumed silica A-300 (S(BET)=337 m2/g) with iron oxide deposits at different content were synthesized using Fe(III) acetylacetonate (Fe(acac)3) dissolved in isopropyl alcohol or carbon tetrachloride for impregnation of the nanosilica powder at different amounts of Fe(acac)3 then oxidized in air at 400-900 degrees C. Samples with Fe(acac)3 adsorbed onto nanosilica and samples with Fe2O3/SiO2 including 6-17 wt% of Fe2O3 were investigated using XRD, XPS, TG/DTA, TPD MS, FTIR, AFM, nitrogen adsorption, Mössbauer spectroscopy, and quantum chemistry methods. The structural characteristics and phase composition of Fe2O3 deposits depend on reaction conditions, solvent type, content of grafted iron oxide, and post-reaction treatments. The iron oxide deposits on A-300 (impregnated by the Fe(acac)3 solution in isopropanol) treated at 500-600 degrees C include several phases characterized by different nanoparticle size distributions; however, in the case of impregnation of A-300 by the Fe(acac)3 solution in carbon tetrachloride only alpha-Fe2O3 phase is formed in addition to amorphous Fe2O3. The Fe2O3/SiO2 materials remain loose (similar to the A-300 matrix) at the bulk density of 0.12-0.15 g/cm3 and S(BET)=265-310 m2/g.Journal of Colloid and Interface Science 07/2009; 338(2):376-88. · 3.07 Impact Factor -
Article: Structural features of polymer adsorbent LiChrolut EN and interfacial behavior of water and water/organic mixtures.
[show abstract] [hide abstract]
ABSTRACT: The structural and adsorption characteristics of polymer adsorbent LiChrolut EN and the behavior of adsorbed water and water/organic mixtures were studied using adsorption, microcalorimetry, transmission and scanning electron microscopy, mass spectrometry, infrared spectroscopy, 1H NMR spectroscopy with layer-by-layer freezing-out of liquids (190-273 K), and thermally stimulated depolarization current method (90-265 K). This adsorbent is characterized by large specific surface area (approximately 1500 m2/g) and pore volume (0.83 cm3/g) with a major contribution of narrow pores (R<10 nm) of a complicated shape (long hysteresis loop is in nitrogen adsorption-desorption isotherm). The adsorbent includes aromatic and aliphatic structures and oxygen-containing functionalities and can effectively adsorb organics and water/organic mixtures. On co-adsorption of water and organics (dimethyl sulfoxide, chloroform, methane), there is a weak influence of one on another adsorbate due to their poor mixing in pores. Weakly polar chloroform displaces a fraction of water from narrow pores. These effects can explain high efficiency of the adsorbent in solid-phase extraction of organics from aqueous solutions. The influence of structural features of several carbon and polymer adsorbents on adsorbed nitrogen, water and water/organics is compared on the basis of the adsorption and 1H NMR data.Journal of Colloid and Interface Science 08/2008; 323(1):6-17. · 3.07 Impact Factor -
Article: Surface structure and properties of mixed fumed oxides.
[show abstract] [hide abstract]
ABSTRACT: A variety of fumed oxides such as silica, alumina, titania, silica/alumina (SA), silica/titania (ST), and alumina/silica/titania (AST) were characterized. These oxides have different specific surface areas and different primary particle composition in the bulk and at the surface. These materials were studied by FTIR, NMR, Auger electron spectroscopy, one-pass temperature-programmed desorption with mass spectrometry control (OP TPDMS), microcalorimetry, and nitrogen adsorption. Nonlinear changes in the surface content of alumina in SA and AST and titania in ST and AST samples with increasing oxide content along with simultaneous changes in their specific surface area cause complex dependencies of the heat of immersion in water and desorption of water on heating on the structural parameters. Simultaneous analysis of changes in the surface phase composition, in the concentration of hydroxyls, and in the structural characteristics reveals that at a low content of the second phase the structural characteristics (e.g., S(BET)) are predominant; however, at a large content of these oxides the phase composition plays a more important role.Journal of Colloid and Interface Science 11/2007; 314(1):119-30. · 3.07 Impact Factor -
Article: Relaxation phenomena in poly(vinyl alcohol)/fumed silica affected by interfacial water.
[show abstract] [hide abstract]
ABSTRACT: Interaction of poly(vinyl alcohol) (PVA) with fumed silica was investigated in the gas phase and aqueous media using adsorption, broadband dielectric relaxation spectroscopy (DRS), thermally stimulated depolarization current (TSDC), infrared spectroscopy, thermal analysis, and one-pass temperature-programmed desorption (OPTPD) mass-spectrometry (MS) methods. PVA monolayer formation leads to certain textural changes in the system (after suspension and drying) because of strong hydrogen bonding of the polymer molecules to silica nanoparticles preventing strong interaction between silica particles themselves. This strong interaction promotes associative desorption of water molecules at lower temperatures than in the case of silica alone. Interaction of PVA with silica and residual water leads to depression of glass transition temperature (T(g)). There are three types of dipolar relaxations at temperatures lower and higher than the T(g) value. A small amount of adsorbed water leads to significant conductivity with elevating temperature.Journal of Colloid and Interface Science 09/2007; 312(2):201-13. · 3.07 Impact Factor -
Article: Comparative characterization of polymethylsiloxane hydrogel and silylated fumed silica and silica gel.
[show abstract] [hide abstract]
ABSTRACT: Polymethylsiloxane (PMS) hydrogel (C(PMS)=10 wt%, soft paste-like hydrogel), diluted aqueous suspensions, and dried/wetted xerogel (powder) were studied in comparison with suspensions and dry powders of unmodified and silylated nanosilicas and silica gels using (1)H NMR, thermally stimulated depolarization current (TSDC), quasielastic light scattering (QELS), rheometry, and adsorption methods. Nanosized primary PMS particles, which are softer and less dense than silica ones because of the presence of CH(3) groups attached to each Si atom and residual silanols, form soft secondary particles (soft paste-like hydrogel) that can be completely decomposed to nanoparticles with sizes smaller than 10 nm on sonication of the aqueous suspensions. Despite the soft character of the secondary particles, the aqueous suspensions of PMS are characterized by a higher viscosity (at concentration C(PMS)=3-5 wt%) than the suspension of fumed silica at a higher concentration. Three types of structured water are observed in dry PMS xerogel (adsorbed water of 3 wt%). These structures, characterized by the chemical shift of the proton resonance at delta(H) approximately 1.7,3.7, and 5 ppm, correspond to weakly associated but strongly bound water and to strongly associated but weakly or strongly bound waters, respectively. NMR cryoporometry and QELS results suggest that PMS is a mesoporous-macroporous material with the textural porosity caused by voids between primary particles forming aggregates and agglomerates of aggregates. PMS is characterized by a much smaller adsorption capacity with respect to proteins (gelatin, ovalbumin) than unmodified fumed silica A-300.Journal of Colloid and Interface Science 05/2007; 308(1):142-56. · 3.07 Impact Factor -

ABSTRACT: Applications of thermally stimulated depolarisation current (TSDC) technique to a variety of systems with different dispersion phases such as disperse and porous metal oxides, polymers, liquid crystals, amorphous and crystalline solids, composites, solid solutions, biomacromolecules, cells, tissues, etc. in gaseous or liquid dispersion media are analysed. The effects of dipolar, direct current (dc) and space charge relaxations are linked to the temperature dependent mobility of molecules, their fragments, protons, anions, and electrons and depend on thermal treatment, temperature and field intensity of polarisation, heating rate on depolarisation or cooling rate on polarisation. Features of the relaxation mechanisms are affected not only by the mentioned factors but also by morphological, structural and chemical characteristics of materials. The interfacial phenomena, especially the role of interfacial water, received significant attention on analysis of the TSDC data. Comparison of the data of TSDC and dielectric relaxation spectroscopy (DRS), differential scanning calorimetry (DSC), 1H NMR spectroscopy with layer-by-layer freezing-out of bulk and interfacial water, adsorption/desorption of nitrogen, water and dissolved organics demonstrates high sensitivity and information content of the TSDC technique, allowing a deeper understanding of interfacial phenomena.Advances in Colloid and Interface Science 03/2007; 131(1-2):1-89. · 8.12 Impact Factor -

ABSTRACT: Structural characterization of different silicas (ordered mesoporous silicas MCM-41, MCM-48, and SBA-15, amorphous silica gels Si-40, Si-60, and Si-100, and initial and wetted-dried fumed silica A-300) and bio-objects (fibrinogen solution, yeast cells, wheat seeds, and bone tissues) has been done using two versions of cryoporometry based on integral Gibbs-Thomson (IGT) equation for freezing point depression of pore liquids measured by 1H NMR spectroscopy (180-200 < T < 273 K) and thermally stimulated depolarization current (TSDC) method (90 < T < 273 K). The IGT equation was solved using a self-consisting regularization procedure including the maximum entropy principle applied to the distribution function of pore size (PSD). Comparison of the PSDs calculated by using the cryoporometry and nitrogen adsorption methods for the mentioned silicas demonstrates that IGT equation provides satisfactory fit which is better than that obtained with nonintegral Gibbs-Thomson (GT) equation (based on the GT equation) proposed by Aksnes and Kimtys. The NMR- and TSDC-cryoporometry methods applied to probe biosystems give clear pictures of changes in the structural characteristics caused, e.g., by hydration and swelling of wheat seeds and yeast cells, coagulation and interaction of fibrinogen with solid nanoparticles in the aqueous media, and human bone tissue disease.Langmuir 03/2007; 23(6):3184-92. · 4.19 Impact Factor -
Article: Relationships between characteristics of interfacial water and human bone tissues.
[show abstract] [hide abstract]
ABSTRACT: Water bound in human bone tissues healthy (sample S1) and affected by osteoporosis (sample S2) was investigated by using 1H NMR spectroscopy with layer-by-layer freezing-out of bulk and interfacial waters at T< 273 K. The 1H NMR spectra of the bound water include two signals which can be assigned to strongly associated typical water (chemical shift of the proton resonance at delta(H) approximately 5 ppm) and weakly associated water at delta(H) approximately 1.4 ppm. Approximately, half of the bound water is in the weakly associated state in S1. A fraction of similar water in S2 is smaller because of the structural difference of the studied samples. The pore size distribution of S2 (in aqueous medium) calculated using the cryoporometry method is characterized by much larger intensity of mesopores and macropores in comparison with that of S1. The total porosity and the surface area of the biostructures (accessible for water molecules and estimated on the basis of the cryoporometry data using a model of cylindrical pores) are larger for S2. Weakly polar chloroform-d has a significant influence on the organization of water in a spongy component of bone tissue. This effect depends on the porosity of the bone matrix and the amounts of CDCl3.Colloids and surfaces. B, Biointerfaces 12/2006; 53(1):29-36. · 2.60 Impact Factor -
Article: Weakly and strongly associated nonfreezable water bound in bones.
[show abstract] [hide abstract]
ABSTRACT: Water bound in bone of rat tail vertebrae was investigated by 1H NMR spectroscopy at 210-300 K and by the thermally stimulated depolarization current (TSDC) method at 190-265 K. The 1H NMR spectra of water clusters were calculated by the GIAO method with the B3LYP/6-31G(d,p) basis set, and the solvent effects were analyzed by the HF/SM5.45/6-31G(d) method. The 1H NMR spectra of water in bone tissue include two signals that can be assigned to typical water (chemical shift of proton resonance deltaH=4-5 ppm) and unusual water (deltaH=1.2-1.7 ppm). According to the quantum chemical calculations, the latter can be attributed to water molecules without the hydrogen bonds through the hydrogen atoms, e.g., interacting with hydrophobic environment. An increase in the amount of water in bone leads to an increase in the amount of typical water, which is characterized by higher associativity (i.e., a larger average number of hydrogen bonds per molecule) and fills larger pores, cavities and pockets in bone tissue.Colloids and Surfaces B Biointerfaces 04/2006; 48(2):167-75. · 3.46 Impact Factor -
Article: Influence of pore structure and pretreatments of activated carbons and water effects on breakthrough dynamics of tert-butylbenzene.
[show abstract] [hide abstract]
ABSTRACT: Several activated carbons differently pretreated (de-ashed, oxidized, reduced, wetted, frozen, and dried) were investigated using static (equilibrium adsorption of nitrogen and benzene) and dynamic (tert-butylbenzene (TBB)) adsorption methods. Treatments of carbons at relatively mild conditions leading to not great changes in their textural characteristics affect the TBB breakthrough concentration because of changes in the chemistry of the surfaces (oxidized or reduced) and the presence of water in airstream or pre-adsorbed on carbon beds. Oxygen-containing functionalities at a carbon surface change condition of competitive adsorption of nonpolar TBB and polar water molecules. Calculations of distribution functions of adsorption potential (A), energy (E), Gibbs free energy (Delta G) of adsorption of benzene and TBB and effective adsorption (first-order) rate pseudoconstant beta e over different ranges of relative exit TBB concentration c(t)/c(0) (from approximately 10(-5) to 0.01-0.4) reveal nonlinear effects caused by the size of carbon granules, the pore size distributions, the presence of water, oxidation or reduction of the surfaces and other treatments resulting in distribution functions f(y) with nonzero intensity in relatively broad ranges of the A, E, Delta G, and beta e values. There are many factors affecting the breakthrough parameters; therefore, simple linear relationships between these parameters and the structural characteristics (S(BET), S(DS), Vp, and V(DS)) are not observed.Journal of Colloid and Interface Science 03/2006; 294(1):53-68. · 3.07 Impact Factor -

ABSTRACT: Thermal analysis was used to study thermal behavior of the sulfonated ion exchange resin Duolite C20 in the hydrogen, sodium and calcium forms. The aim of this paper was to prepare spherical carbon adsorbents. SEM and AFM microscopic methods have been applied to describe their surface characteristics. It was stated that structural parameters of prepared active carbons depend on the kind of cation present in the resin. The use of calcium form of Duolite C20 as the initial polymer precursor allowed to obtain the active carbon with better yield and better developed pore structure compared with other forms of this ion exchanger.Journal of Thermal Analysis and Calorimetry 01/2006; 86(1):187-194. · 1.60 Impact Factor
