Opis:
The effects of different types of arbuscular mycorrhizal (AM) fungi on the root inoculation and plant elemental content of lupin (Lupinus albus L.) were investigated in the present study. The growth and development of lupin were examined to determine the species of AM fungi that can help to grow lupin with a high protein content and economic value. In this study, which was carried out as a pot experiment under controlled greenhouse conditions, first the pots were inoculated with Glomus geosporum, Glomus mosseae, Glomus caledonium, Glomus etunicatium mycorrhizal spores and then lupin (Lupinus albus) seeds were sown. The plants were watered with pure water during the experiment. The trial was terminated after a 60-day plant gowing period. In the study, inoculation occurred at lupin roots at rates varying between 13.3 and 30.0%. However, there was no statistically significant difference among the types of arbuscular mycorrhizal fungi applied to the plant in the inoculation rate. The examination of the effect of the application of different AM (Glomus geosporum, Glomus mosseae, Glomus caledonium, Glomus etunicatium) spore on the plant development showed that AM inoculation did not have an effect on the lupin development. The effect of AM inoculation on the plant’s nutrient content revealed no significant difference in the content of crude protein, P and K, while demonstrating a significant increase in the sulphur and magnesium content versus the control. The plant content of crude protein varied between 185.6 and 226.5 (g kg-1), phosphorus – 0.61-0.74 (g kg-1) and potassium – 9.6-11.1 (g kg-1). The concentrations of Zn, Cu, B and Mo in lupin did not show statistically significant modifications caused by the inoculation of different types of AM. However, the plant Mn content showed a decrease due to AM inoculation, whereas a significant increase was observed in the Na content after AM inoculation. AM fungi were observed in plant roots after the inoculation with any of the four different types of mycorrhiza. But no positive effects of mycorrhizal inoculation were not observed on crude protein and the uptake of plant nutrients.

Opis:
In this work, NiFe nanowires were grown in highly ordered porous anodic alumina oxide templates by dc electrodeposition at a pH value of 2.6. Scanning electron microscopy showed that wires have diameters of about 250-310 nm and length 25-30 μm. The energy dispersive X-ray analysis showed that the composition of the nanowires is $Ni_{65}Fe_{35}$. Electrical contacts were made on both sides of the nanowire array and their magnetoimpedance properties were investigated. All the magnetoimpedance curves showed single peak behavior due to the high shape anisotropy. The maximum magnetoimpedance change at the 79 MHz driving current frequency was ≈ 1.45%.

Opis:
Co/Cu multilayer nanowires were electrodeposited potentiostatically on highly ordered porous anodic alumina oxide templates. Scanning electron microscopy (SEM) showed that wires have diameters of about 250-300 nm and length of 40-50 μm. Co/Cu multilayer nanowire arrays embedded in anodic alumina oxide were mechanically polished with diamond in a suspension of oil until the wires appeared. Then the top and bottom surfaces of the material were coated with a layer of Au with a thickness of 100 nm for electrical contacts. Magnetic field was applied by an electromagnet and resistance was measured by four point technique.

Opis:
CoNiFe and NiFe nanowires were electrochemically produced by dc electrodeposition on highly ordered porous anodic alumina oxide templates. Scanning electron microscope images of nanowires after removing the alumina membrane showed that these nanowires are uniform with the diameters of about 220-300 nm and about 25-30 μm length. The energy dispersive X-ray analysis showed that the composition of the nanowires is $Ni_{88}Fe_{12}$, $Co_7Ni_{82}Fe_{11}$. Magnetic field was applied by an electromagnet and resistance was measured by four point technique.

Opis:
The crystal structure determination of the methylated pyrazine-2-carbohydrazide derivative, namely N-methyl-N'-(4-nitrobenzylidene)pyrazine-2-carbohydrazide were optimized to obtain its molecular geometric structure and electronic structures at the Hartree-Fock and density functional theory levels (B3LYP) with 6-311G(d,p) and 6-311++G(d,p) basis sets, using Gaussian 09W programme. The $\text{}^{1}H$ and $\text{}^{13}C$ nuclear magnetic resonance chemical shifts of the title molecule were calculated by using the gauge independent atomic orbital, continuous set of gauge transformations and individual gauges for atoms in molecules methods and were also compared with experimental values. The electronic properties high occupied and low unoccupied molecular orbitals energies were calculated and analyzed. Potential energy surface scan, natural population analysis and Mulliken atomic charges were investigated using theoretical calculations. A detailed molecular picture and intermolecular interactions arising from hyperconjugative interactions and charge delocalization of the molecule were analyzed using natural bond orbital analysis.

Opis:
The molecular structure of 1-(5-bromothiophen-2-yl)-3-(4-nitrophenyl)prop-2-en-1-one with $C_{13}H_8BrNO_3S$ empirical formula was simulated using B3LYP and CAM-B3LYP levels of density functional theory. After BTNP was optimized on the ground state, its characterization was enhanced via IR, NMR and UV-vis spectroscopies. Conformational analysis was performed based on B3LYP level so as to find the stable conformers of BTNP. Electronic transitions were calculated, and the important contributions from the molecular orbitals to the electronic transitions were investigated. HOMO and LUMO energies were calculated, and obtained energies displayed that charge transfer occurs in BTNP. It was displayed that BTNP is an efficient NLO material due to the coplanar of phenyl-nitro group and carbonyl group. NBO analysis also proved that charge transfer, conjugative interactions and intramolecular hydrogen bonding interactions occur through BTNP.
