Аннотация:
The state of iron in nanoparticles prepared by impregnating silica gel and aluminum oxide with iron(II) sulfate solutions has been investigated using Mossbauer spectroscopy. It has been revealed that the state of iron depends on the nature of the support. Iron(III) hydroxysulfate and iron(III) oxysulfate nanoparticles are formed on the surface of silica gel, and iron oxide nanoparticles are formed on the surface of aluminum oxide. An increase in the concentration of iron ions or in the size of iron-containing particles leads to hydration of the nanoparticle surface. The calcination of the samples results in the formation of E -Fe2O3 oxide in a strongly disordered or amorphous state in iron-containing particles on the surface of silica gel.

Аннотация:
Ferrihydrite
nanoparticles (2-5 nm in size) produced by bacteria Klebsiella oxytoca in the course of biomineralization of iron salt solutions from a natural medium exhibit unique magnetic properties: they are characterized by both the antiferromagnetic order inherent in a bulk
ferrihydrite
and the spontaneous magnetic moment due to the decompensation of spins in sublattices of a nanoparticle. The magnetic susceptibility enhanced by the superantiferromagnetism effect and the magnetic moment independent of the magnetic field provide the possibility of magnetically controlling these natural objects. This has opened up the possibilities for their use in nanomedicine and bioengineering. The results obtained from measurements of the magnetic properties of the
ferrihydrite
produced by Klebsiella oxytoca in its two main crystalline modifications are reported, and the data obtained are analyzed theoretically. This has made it possible to determine numerical values of the magnetic parameters of real biomineral nanoparticles.

Ferrihydrite
nanoparticles formed as a result of the microorganism activity have been studied using Mossbauer spectroscopy, X-ray powder diffraction analysis, and X-ray fluorescence analysis. Three positions of trivalent iron with nonoverlapping ranges of quadrupole splittings have been revealed in bacterial
ferrihydrite
: QS{Fe(3+)(1)} = 0.49-0.83 mm/s, QS{Fe(3+)(2)} = 0.84-1.10 mm/s, and QS{Fe(3+)(3)} = 1.25-1.73 mm/s. It has been experimentally demonstrated that the Fe(3+)(3) positions are the centers of nucleation of the hematite phase in the course of heat treatment.

Аннотация:
The magnetic properties of antiferromagnetic nanoparticles of FeOOH · nH2O with sizes of 3–7 nm, which are products of vital functions of Klebsiella oxytoca bacteria, have been studied. Particles exhibit a superparamagnetic behavior. The characteristic blocking temperature is 23 K. Analysis of the magnetization curves shows that the mechanism of the formation of the uncompensated magnetic moment of particles is the random decompensation of magnetic moments of Fe3+ ions both on the surface and in the bulk of the antiferromagnetic particle. In this mechanism, the exchange coupling between the uncompensated magnetic moment of the particle and its antiferromagnetic “core” is implemented. It has been found that the temperature dependence of the uncompensated magnetic moment has the form 1 — constT 2.

Исследованы магнитные свойства антиферромагнитных (AF) наночастиц ферригидрита FeOOH• nH2O размером 3-7 нм, являющихся продуктом жизнедеятельности бактерий Klebsiella oxitoca. Частицы демонстрируют суперпарамагнитное поведение. Характерная температура блокировки составляет 23 K. Анализ кривых намагничивания показал, что механизмом формирования нескомпенсированного магнитного момента частиц является случайная раскомпенсация магнитных моментов ионов Fe3+ как на поверхности, так и в объеме AF-частицы. При этом реализуется обменная связь между нескомпенсированным магнитным моментом частицы и ее AF "ядром". Установлено, что температурная зависимость нескомпенсированного магнитного момента подчиняется закону {\sim} (1-\text{const}T. ).

Аннотация:
A study was conducted to estimate the possibility of formation of chains of superparamagnetic nanoparticles of iron oxyhydroxides synthesized in a bacteria culture. The self-assembly of biogenic nanoparticles distinguished by low values of magnetization and small sizes is assumed to proceed due to the forces of magnetic dipole dipole interaction as an initial mechanism of aggregation and exchange-interaction forces, which provide the stability of chains. The microphotographs demonstrate the self-assembly of anisotropic cobalt-doped
ferrihydrite
nanoparticles in aggregates of ellipsoidal shape with sizes of about 550 × 300 nm and a platelike shape of 50-100 nm thick. The aggregates, in turn, are combined from blocks, which include a restricted number of nanoparticles of about 5 nm in diameter and have the shape of rods of 50-100 × 12 nm in size. The energy of degaussing fields of chains is reasonably high, which forces them to form two and three dimensional structures in which the compensation of such fields is provided.

Аннотация:
Bacterial culture Klebsiella oxytoca was grown in a Lovley medium at various concentrations of gadolinium salt. Biogenic magnetic nanoparticles of
ferrihydrite
were investigated by Mossbauer spectroscopy and magnetization curves were obtained. The results of structural studies showed that iron Fe(5) takes new position when cultivating is carried out in medium with high concentrations of gadolinium. It was found that gadolinium is fit into the crystal structure of
ferrihydrite
. These results are consistent with the analysis of the magnetization curves.

The magnetic properties of the superparamagnetic
ferrihydrite
nanoparticles that form as a result of the vital activity of Klebsiella oxytoca bacteria are studied. Both an initial powder with an average number of iron atoms N Fe ∼ 2000–2500 in a particle and this powder after annealing at 140°C for 3 h in air are investigated. The following substantial modifications of the magnetic properties of the
ferrihydrite
nanoparticles are detected after annealing: the superparamagnetic blocking temperature increases from 23 to 49.5 K, and the average magnetic moment of a particle increases (as follows from the results of processing of magnetization curves). The particles have antiferromagnetic ordering, and the magnetic moment resulting in the superparamagnetism of the system appears due to random spin decompensation inside the particle. For this mechanism, the number of uncompensated spins is proportional to the number of magnetically active atoms raised to the one-half power, and this relation holds true for the samples under study at a good accuracy. The possible causes of the detected shift of magnetic hysteresis loops at low temperatures upon field cooling are discussed.

Аннотация:
We have studied the influence of low-temperature heat treatment (annealing) on the magnetic properties of superparamagnetic nanoparticles of biogenic
ferrihydrite
. It is established that the proposed treatment leads to an increase in the blocking temperature and magnetic susceptibility of samples. After subsequent exposure in aqueous medium, the magnetic properties of annealed sol remain constant. The character of changes in the magnetic properties of samples studied shows that low-temperature heat treatment allows nanoparticle dimensions to be increased in a controlled way. © 2015, Pleiades Publishing, Ltd.

Аннотация:
The results of the investigation into the effect of low-temperature annealing of a powder of nanoparticles of bacterial
ferrihydrite
on its magnetic properties have been presented. It has been found that an increase in the time (up to 240 h) and temperature (in the range from 150 to 200°C) of annealing leads to a monotonic increase in the superparamagnetic blocking temperature, the coercive force, and the threshold field of the opening of the magnetic hysteresis loop (at liquid-helium temperatures), as well as to an increase in the magnetic resonance line width at low temperatures and in the magnetic susceptibility at room temperature. At the same time, according to the results of the analysis of the Mossbauer spectra, the annealing of
ferrihydrite
does not lead to the formation of new iron oxide phases. Most of these features are well consistent with the fact that the low-temperature annealing of
ferrihydrite
causes an increase in the size of nanoparticles, which is confirmed by the results of transmission electron microscopy studies. © 2016, Pleiades Publishing, Ltd.

Аннотация:
We report the results of investigations of the effect of cooling in an external magnetic field starting from the temperature over superparamagnetic blocking temperature TB on the shift of magnetic hysteresis loops in systems of
ferrihydrite
nanoparticles from ∼2.5 to ∼5 nm in size with different TB values. In virtue of high anisotropy fields of
ferrihydrite
nanoparticles and open hysteresis loops in the range of experimentally attainable magnetic fields, the shape of hysteresis loops of such objects in the field-cooling mode is influenced by the minor hysteresis loop effect. A technique is proposed for distinguishing the exchange bias effect among the effects related to the minor hysteresis loops caused by high anisotropy fields of
ferrihydrite
particles. The exchange bias in
ferrihydrite
is stably observed for particles not less than 3 nm in size or with TB over 40 K, and its characteristic value increases with the particle size. © 2016 Author(s).

Аннотация:
The precipitation of iron and associated heavy metals in industrial waste water and in model solution using ferritization and aerobic bacterial culture was investigated. Magnetic sediments extractable by magnetic separation (specific saturation magnetization of 16–36.8 G cm3/g) were produced by precipitation of iron by ferritization method at рН (8–10) and 60–80°С for 15–30 min. Nanoparticles of
ferrihydrite
or ferric hydroxide doped with associated metals (Co, Ni) were produced under precipitation of ferric iron in model solution with bacteria at the temperature 26–34°С. The radii of synthesized particles are 1–5 nm and nanoparticles of
ferrihydrite
are superparamagnetic in both un-doped and doped (Co, Ni, Zn) sets. Dispersed structure of biogenic nanoparticle sols, their magnetic and other properties were studied by atomic force microscopy, X-ray small-angle scattering, X-ray diffraction, electron magnetic resonance, Mössbauer and X-ray photoelectron spectroscopy.
