Between 2003-2007, abomasa of 91 European bison (Bison bonasus), 4 red deer (Cervus elaphus) and 2 roe deer (Capreolus capreolus) shot in the Białowieza Primeval Forest (Poland) were examined for worms presence. All the animals examined were infected with nematodes A. sidemi with an exception of one bison, that was sh…
This work described the photoluminescent (PL) and thermal stability properties of -doped phosphors, with the composition that can be excitable under vacuum UV (VUV) light. The concentration of Tb as a fraction of that of Ca was varied from . The sample with had the highest emission intensity. The obtained activation e…
Three series of waterborne polyurethane (WBPU)/carbon nanotube (CNT) nanocomposites were prepared, and their morphology and properties with various 2,2-dimethylol propionic acid (DMPA) and CNT contents were investigated. The CNTs were homogeneously dispersed up to the optimum content in WBPU/CNT nanocomposite films. T…
Prussian blue nanoparticles (PB NPs), stabilized for the first time by the pi-conjugated polymer poly(4-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2yl-methoxy-1-butanesulfonic acid, potassium salt) (PEDOT-S), demonstrated a novel multiple-color pH-sensing function with a redox reaction based on the electronic interaction be…
A novel cobalt compound [Co(9)(HL)(4)(L)(4)Cl(2)] x (EtOH)(2)(H(2)O)(2) (H(3)L = (E)-2-2((1,3-dihydroxy-2-methylpropan-2-ylimino)methyl) phenol) has been solvothermally synthesized and structurally characterized. The compound crystallised in the space group C2/c with a = 32.624(2) A, b = 9.4814(4) A, c = 33.395(2) A,…
TiMn alloy was prepared by mechanical alloying and subsequently consolidated by spark plasma sintering (SPS) technique for exploration of biomedical applications. The microstructures, mechanical properties and cytotoxicity of the TiMn alloys were investigated in comparison with the pure Ti and Mn metals. Ti8Mn and Ti1…
OFETs built from extended TTF derivatives containing N-methylpyrrole, furan, thiophene and benzene with meta or para linkages as spacers are presented. The aromatic spacer plays a crucial role in the characteristics and stability of the OFETs. The less conjugated derivative with a meta-benzene moiety as spacer has the…
Pure and Gd 3+ ‐doped titanate nanotubes (TNTs) materials were synthesized by a hydrothermal method. Their morphology, optical properties, thermal stability, and magnetic properties were characterized by X‐ray diffraction (XRD), transmission electron microscope (TEM), UV‐Vis spectroscopy, thermal analysis, and magneti…
In this work the 2H NMR spin-lattice relaxation times, T1Z and T1Q, and the spin-spin relaxation times measured by means of the quadrupolar echo sequence, T2, have been analyzed in order to study the dynamic processes of a liquid crystalline dendrimer labelled on the aromatic core of the lateral mesogenic units in the…
A new salt of ziprasidone with high aqueous solubility has been discovered as a result of a salt screening and it has been found to exist in three anhydrous polymorphic forms. One of these forms shows the highest aqueous solubility ever reported for ziprasidone salts in combination with a high kinetic stability, becom…
A water-soluble poly(m-phenylene) bearing an achiral oligo(ethylene oxide) chain at the 5-position was synthesized by the Ni(0)-mediated homo-coupling polycondensation of a 3,5-dibromophenol monomer. The poly(m-phenylene) adopted a single helical conformation in protic media and self-assembled into a double helix in w…
In the present paper, we discuss the influence of point defects on electrical and optical characteristics of ZnO thin films grown by the atomic layer deposition (ALD) method. The films were grown on glass substrates at low temperature (100–200 °C). We used diethylzinc (DEZn) and deionized water as precursors. Room tem…
The conductivity of A- (Ca and Sr) and B-site (Ti) acceptor doped and has been characterized by means of constant frequency measurements and ac impedance spectroscopy in the temperature range of , and as a function of the partial pressures of oxygen and water vapor. Effects of H–D isotope shifts on the total conductiv…
We investigate the dependence of the optical conductivity of bilayer graphene (BLG) on the intra and interlayer interactions using the most complete model to date. We show that the next nearest neighbor intralayer coupling introduces new features in the low energy spectrum significantly changing the 'universal' conduc…
Micropatterned surfaces have been used as a tool for controlling the extent and strength of cell adhesion, the direction of cell growth and the spatial distribution of cells. In this study, chemically micropatterned surfaces were prepared by successive plasma polymerization of acrylic acid (AA) and 1,7-octadiene (OD)…
The crystal structure of the monomeric vanadium(III) species mer-[V(bipy)Cl(3)(MeCN)] (1; bipy = 2,2'-bipyridine) is reported. The solvothermal reaction of [V(bipy)Cl(3)(MeCN)]with Na(O(2)CPh) yields the T-shaped cluster [V(3)(O)Cl(3)(O(2)CPh)(2)(bipy)(2)(OEt)(2)], magnetic studies of which show strong intramolecular…
Electro-oxidation of Mn 2+ to MnO 2 by cyclic voltammetry on gold in acidic ͑0.1 M H 2 SO 4 ͒ and neutral ͑0.1 M Na 2 SO 4 ͒ media was studied using electrochemical quartz-crystal microbalance ͑EQCM͒.The cyclic voltammetric behavior of Au is different in these electrolytes.From EQCM data of mass variation during cycli…
First principles calculations reveal that formation of a fully ionized oxide vacancy leads to local condensation of coordination polyhedra forming Nb3O11(7-) in t-LaNbO4.
The effect of β-irradiation on silicate and aluminoborosilicate glasses doped with transition metals (TM) and rare earth (RE) elements has been studied using Electron Paramagnetic Resonance (EPR), Raman and luminescence spectroscopy.
