Background. The modern concept of acute leukemia therapy involves stratification patients into prognostic risk groups and a differentiated approach to treatment based on factors. However, antitumor treatment, including cytostatics, targeted agents, immunotherapy, cellular technologies, is not always highly effective, especially in with poor prognosis. development new high-tech diagnostic method...

Biofilm bacteria are more resistant to antibiotics than planktonic cells. Propolis possesses antimicrobial activity. Generally, nanoparticles containing heavy metals possess antimicrobial and antibiofilm properties. In this study, the ability of adherence of Methicillin Resistant Strains of Staphylococcus aureus (MRSA) to catheters treated with magnetite nanoparticles (MNPs), produced by three ...

A β-aminoacid ester was successfully derivatized to yield to 4H-1,2-4-triazol-4-yl-propionate (βAlatrz) which served as a neutral bidentate ligand in the 1D coordination polymer [Fe(βAlatrz)(3)](CF(3)SO(3))(2)·0.5H(2)O (1·0.5H(2)O). The temperature dependence of the high-spin molar fraction derived from (57)Fe Mossbauer spectroscopy recorded on cooling below room temperature reveals an exceptio...

Ž . Although dissimilatory iron reducing bacteria DIRB are capable of reducing a number of metals in oxides and soluble forms, the factors controlling the raterextent of magnetite reduction and the nature of the mineral products resulting from magnetite reduction are not well understood. This study was carried out to investigate mechanisms and biogeochemical processes occurring during magnetite...

High-field susceptibility results ~re presented for MOssbauer measurements on iron at low temperatures m field.s up ~o 13~ kOe and magnetIZatIOn measurements on iron and nickel single crystals in fields up to 148 kOe WIth vibratmg sample magneto~eters. The Mossbauer measurements give the hyperfine field H n = Hint(HO-1!I:!M) +AH, where !lint IS the hyperfine field at zero applied field,Ho is ...

Large-area antimony telluride (Sb2Te3) thin films are grown by a metal organic chemical vapor deposition technique on 4” Si(111) substrates, and their topological character probed magnetoconductance measurements. When interfaced with Fe films, broadband ferromagnetic resonance spectroscopy (BFMR) shows clear increase of the damping parameter in Fe/Sb2Te3 when compared to reference layer, which ...

The influence of different carbon sources, including anthracite, calcined petroleum coke, three samples high-temperature biochar, and a mixture 50 wt.% biochar on slag foaming behavior was studied. slag’s composition set to FeO-CaO-Al2O3-MgO-SiO2, the temperature for 1600 °C. effect sources evaluated using characteristics (foam height, foam volume, relative gas fraction), X-ray diffraction (XRD...

The molecular structure of the prototypical chalcogenide glass system—GexSe1 x in the 0oxo3 range, has received much scrutiny over the years. These glasses have been probed by modulated DSC, Raman scattering, Sn absorption and I emission Mössbauer spectroscopy, and neutron scattering. The I measurements utilize Te parent as a dopant in glasses, and reveal a bimodal (A, B) distribution of sites,...

The effect of applied pressure on the magnetic properties of the Prussian blue analogue K0.4Fe4[Cr(CN)6]2.8 x 16 H2O (1) has been analyzed by dc and ac magnetic susceptibility measurements. Under ambient conditions, 1 orders ferromagnetically at a critical temperature (T(C)) of 18.5 K. Under application of pressure in the 0-1200 MPa range, the magnetization of the material decreases and its cri...
