We report on PbS colloidal nanocrystals that combine within one structure solubility in physiological solvents with near-infrared photoluminescence, and magnetic and optical properties tuneable by the controlled incorporation of magnetic impurities (Mn). We use high magnetic fields (B up to 30 T) to measure the magnetization of the nanocrystals in liquid and the strength of the sp-d exchange in...

the complexes of mn(oac)3 and/or mn(acac)3 with nucleic bases and nucleosides (adenine, guanine, xanthine, adenosine and guanosine) have been synthesized in nonaqueous solution. polarographic and spectroscopic (ir and visible) methods have been used to establish the active site(s) on the imidazole and pyrimidine rings in the nucleic bases and nucleosides for the interaction with the mn(iii) com...

A dinuclear manganese(III) complex (1) of an N-(carboxymethyl)-N-[3,5-bis(α,α-dimethylbenzyl-2-hydroxybenzyl)]glycine (HDA) ligand (L) binds a manganese(II) species through displacement of its solvating ligands by appropriately dispositioned carbonyl groups of a dinuclear complex {[Mn(2)(L)(2)(OH)(OCH(3))][Mn(H(2)O)(3)(CH(3)OH)(3)], 2, triclinic P1, a = 13.172(3) Å, b = 15.897(3) Å, c = 19.059(...

This study is aimed at producing a biofoam cup made from sugarcane bagasse with tempeh mold (Rhizopus oligosporus). Soybean flour (SF) was added to promote the growth of mycelia, which could bind fiber matrix. The main materials were whole (B) and depithed (DB). SF weight ratios 1 : (SF1) 1.5 (SF1.5). Therefore, studied specimens labeled B-SF1, DB-SF1, B-SF1.5, DB-SF1.5. All cups analyzed for t...

The Mn atom in the title compound, [Mn(2)(C(7)H(3)N(2)O(6))(4)(C(10)H(8)N(2))(2)](n), is six-coordinated by two N atoms and four O atoms, forming a distorted octa-hedral geometry. The Mn-O bond lengths are in the range 2.1281 (13)-2.2011 (12) Å and the Mn-N bond lengths are 2.269 (2) and 2.278 (2) Å. Mn(II) atoms are double-bridged along the a axis by two pairs of bi-monodentate carboxyl groups...

Background: Most of the cytogenetic dosimetry, except Premature Chromosome Condensation assay, saturates at 6 Gy. Present studies are aimed to assess feasibility of simple CB-MN assay for prescreening of high dose accidental exposures. Materials and Methods: Human peripheral blood lymphocytes from two donors were gamma irradiated to different doses ranging from 0-15Gy, cultured for 72 h. Cytoch...
