Method of obtaining of nickel-carbon composites of various morphology reduction metal solution to the carbon substrate is developed. Composite comprises nickel nanoparticles with dimensions of 4-12 nm.
Following our previous studies,1 novel (arene)ruthenium(II) complexes containing neutral chelating nitrogen ligands, with general formula [Ru(arene)(L’)Cl]Cl, have been prepared by reacting the ligands L’ (L’ in general; in detail, L1 = bis(pyrazol-1-yl)methane; L2 = bis(3,5-dimethylpyrazol-1-yl) methane) with some di…
The study area is located in Duhok and Sulaimania province in Kurdistan region, Iraq. Study soils developed from parent material that has derived from limestone. Randomize, composed and disturbed surface soil samples were collected. The bulk soils were air dried, crushed and passed through 2 mm sieve. Standard methods…
CsBr: (Eu 2+ , KOH) powders were prepared by solid-state reaction. The photo luminescence (PL) spectra, photostimulated luminescence (PSL) spectra, Raman spectra and PSL lifetime spectra were systematically investi- gated, and the influence of KOH-adding on photostimulated luminescence and radiation hardness propertie…
Exercise training stimulates angiogenesis in locomotor muscles. We hypothesize that skeletal myofiber expressed vascular endothelial growth factor is necessary for this angiogenic response to exercise training and overall improvements in exercise capacity. A conditional skeletal myofiber-specific VEGF gene deletion ad…
Miscibility and mechanical properties of natural rubber (NR) based non polar synthetic rubber blends were described in relation to the molecular structure of the rubber. The miscible blend was prepared from NR and butadiene rubber (BR) having 32.3% 1,2-units. The lower critical solution temperature (LCST) phase behavi…

In a dynamic nutrient environment, cells commit to metabolic pathways to utilize the nutrients that are available, which is determined at the level of gene regulation. Specifically, yeast Saccharomyces cerevisiae cells undergo a metabolic shift from glycolysis to gluconeogenesis in the absence of the fermentable carbo…
We use benzyl bromoacetate as 2-N substituted alkylation to react with N-confused porphyrin to afford 2-aza-2-benzyloxycarbonylmethyl-5,10,15,20-tetraphenyl-21-carbaporphyrin (2-NCH2COOCH2C6H5NCTPPH) (2). After 2-N substituted alkylation, we use Ni(OAc)2∙4H2O, PdCl2, PtCl2, MnBr2 and CoCl2∙6H2O to react seperately wit…
Effect of BaSnO 3 (BSO) nanoparticle inclusion on the critical current density of GdBa 2Cu 3O7-x (GdBCO) thin films was investigated. BSO nanoparticles were prepared on a thin GdBCO seed layer of < 50 nm thick by using pulsed laser deposition (PLD) technique. The GdBCO superconducting layers were deposited on top of t…
Рассмотрена технология получения композиционного порошка на основе диоксида циркония.
Diatoms are single-celled aquatic algae that are involved in approximately one-fifth of photosynthesis globally and fix as much carbon as all of Earth’s rainforests combined. One reason for this evolutionary success is that diatoms live within the confines of an intricate outer cell wall composed mainly of silica. Dia…
РОЛЬ ПЛАСТИЧЕСКОЙ ДЕФОРМАЦИИ В СТАБИЛИЗАЦИИ СТРУКТУРЫ И ФУНКЦИОНАЛЬНЫХ СВОЙСТВ НИКЕЛИДА ТИТАНА М.А.Хусаинов, Н.В.Петров, О.А.Малухина THE INFLUENCE OF PLASTIC DEFORMATION ON STABILIZATION OF THE STRUCTURE AND FUNCTIONAL PROPERTIES OF TITANIUM NICKELIDE М.А.Khusainov, N.V.Petrov, О.А.Malukhina Политехнический институт…
In this work we studied the influence of exogenous ammonium on the total protein and chlorophyll contents, on the number of ribosomes and on the expression of ribosomal genes encoding the small subunit 18S rRNA and rpS6 protein in unicellular green alga Chlamydomonas reinhardtii and in callus tissue of Glycine max. Co…
In order to promote the corrosion resistance of magnesium alloy, an MgO/ZrO2 duplex-layer coating has been prepared on AZ91D magnesium alloy as a protective film against corrosion by a two-step fabrication process of electrodeposition and annealing treatment in the study. Owing to the chemical bonding formed after the…
Graphene has become one of the most widely researched materials lately since its discovery in 2004. It has interested scientists due to the exceptional electronic properties of the relativistic Dirac fermions. In this thesis I will present the research I have done to study the charged impurity scattering mechanism in…
Insulin assembly follows different pathways under different environments. But the mechanism of insulin assembly and the pathology of insulin-related amyloidosis diseases remain unclear. This work, illustrating different pathways of insulin aggregation induced by short peptide segment, may shed light on these research…
Die Entwicklung Nanomedizin-basierter Therapeutika (Nanomedizin = medizinsche Anwendung der Nanotechnologie) hat zum Ziel, pharmakologische Substanzen zielgerichtet zu ihrem Wirkort zu transportieren und so die mangelnde Gewebsspezifität konventioneller Wirkstoffe zu überwinden. Humanes Serumalbumin bietet sich als Ba…
Empty 55-gallon drums that formerly held transuranic (TRU) waste (often over-packed in 85gallon drums) are generated at LANL and require radiological characterization for disposition. These drums are typically measured and analyzed individually using high purity germanium (HPGe) gamma detectors. This approach can be r…
For the purpose of improving the electrochemical cycle stability of the La-Mg-Ni based A2B7-type electrode alloys, both reducing Mg content and substituting La with Pr were adopted. The La0.8-xPrxMg0.2Ni3.15Co0.2Al0.1Si0.05 (x=0, 0.1, 0.2, 0.3, 0.4) electrode alloys were fabricated by casting and annealing. The invest…
