A cleavage–reorganization reaction at room temperature has been detected in three metal organic coordination compounds synthesized from a DPDS [di(4-pyridyl)disulphide] ligand: Mn(NCS) 2 (DPS) 4 ( 1 ), [Fe(NCS) 2 (DPS) 2 ]·2H 2 O ( 2 ) and Zn(NCO) 2 (DPS) ( 3 ), [DPS = di(4-pyridyl)sulphide].
This work investigates the effect of critical properties on aged transformer oil with various additives such as semiconductive nanoparticles, natural and synthetic antioxidants. The additives are added with aged transformer oil in different fraction with the objective to enhance the critical properties of oil and elim…
The sensitivity of four different CPV module technologies to most operating conditions relevant to CPV systems has been studied, namely DNI, spectrum, cell and lens temperature and clearness of the sky.In order to isolate the influence of a single operation parameter, the analysis of long-term outdoor monitoring data…
Hydrogen does not generally exist in the free-state rather it occurs in compounds which means other energy sources have to be used to separate it. Broadly speaking, the compounds are water, natural gas and coal or biomass. Selection of the method of separation determines the overall environmental impact of hydrogen. O…
Uranium is vital to nuclear power generation. Its hazard is a formidable threat to life forms. A small portion of a regional land mass - not known for uranium mining was analyzed to examine the risk of future environmental pollution when the proposed nuclear plant is cited in the country. The bye product of the spot d…
А. И. БуфетовЭргодическое разложение для мер, квазиинвариантных относительно борелевских действий индуктивно компактных группЦель настоящей работы -доказать теоремы об эргодическом разложении для вероятностных мер, квазиинвариантных относительно борелев
Recent announcement of 16Gbits Resistive memory from Sony shows the trend to quickly adopt resistive memories as an alternative to DRAM. However, using ReRAM for embedded computing is still a futuristic goal. This paper approaches two applications based on ReRAM-devices for gaining area, performance or power consumpti…
The work deals with development of a new approach for forecasting a high-cycle fatigue lifetime of bolted connection of hydro turbines runner. Operation of hydro turbines on normal operation condition does not lead to high stresses rates in bolted connection. However the high cycle fatigue failures have been occurred.…
Infrared thermography (IRT) is used to get information on the behavior of thermoplastic matrix composites under low velocity/energy impact. Indeed, infrared thermography proved already its usefulness in the investigation of impact damaging of composites, as both surface thermal mapping when the specimen is being impac…
Selected mechanical parameters of earlywood and latewood from Pinus sylvestris subjected to tensile stress were measured as a function of moisture content. Microfibril angles (MFAs) to the longitudinal axis of the cell in the S2 layer of tangent cell walls in the same wood samples were also measured. The tensile stren…
Synthesis of a new heteroleptic trinuclear Ru( ii ) complex of a ditopic imidazole-based terpyridine bridging ligand and its room temperature luminescence in fluid solution and pH modulated luminescence behaviour is reported.
A novel trigeminal zinc porphyrin sensitizer (T) and two zinc porphyrin monomers (M1 and M2) were successfully designed and synthesized. The spectral, electrochemical, and photovoltaic properties of the porphyrin dyes were investigated. Compared with M1, the molecule of M2 has an additional aliphatic n-hexyloxyl chain…
Microstructures of the new PM superalloy N19 have been investigated for various heat treatments in order to reach the best compromise between static strength and cyclic resistance. One subsolvus and several supersolvus heat treatments were applied to produce fine (7 μm) and medium (25 μm) grain sizes, respectively. Th…
Cationic polymerizable bisazobenzene-containing vinyl ether, which is being referred to as VEBiB, was synthesized and its cationic copolymerization with isobutyl vinyl ether (IBVE) using Et1.5AlCl1.5 as the catalyst, ethyl acetate as the added base, and 1-isobutoxyethyl acetate (IBEA) as the initiator was investigated…
Elevated temperatures that are often required for controlled radical polymerization processes lead to the thermal autopolymerization of 4-vinylbenzyl piperidine. In situ FTIR spectroscopy monitored 4-vinylbenzyl piperidine autopolymerization, and pseudo-first-order thermal polymerization kinetics provided observed rat…
We report an antibacterial and wash durability behaviour of MgO and NiO nanoparticles treated cotton fabric using sodium alginate as cross linker. The metal oxide nanoparticles treated cotton fabric using sodium alginate as a crosslinker was characterized employing SEM-EDX and their antibacterial activity was analyzed…
The density, conductivity and viscosity of aqueous solutions of acetamide-LiCl eutectic ionic liquid were investigated at atmospheric pressure and temperatures from (303.15 to 343.15) K and within the whole composition range. The density values decrease linearly with the increase of the mass content of water and the d…
In this study, we fabricated copper(II) complex/n-Si/Au organic-inorganic heterojunction diode by forming copper(II) complex thin film on n-type silicon. A direct optical band gap energy values of the copper(II) complex (Cu2C34H34N2O21Cl4) thin film on a glass substrate was obtained as Eg=2.98 eV. The current-voltage…
The relation between flame radiation, smoke yield, and smoke point of a practical solid fuel, namely corrugated cardboard, is studied experimentally. Experiments are performed using an ASTM E 2058/ISO 12136 Fire Propagation Apparatus (FPA). Corrugated cardboard flames are established in the FPA under external heat flu…
By a one-pot method, monodisperse micro/nanoscale Zn-based coordination polymers (CPs) were synthesized. The morphologies of products could be feasibly modulated with the change of the synthesis medium. These CPs were used as precursors to prepare ZnO architectures, which are mesoporous, inherit the morphology of CP p…
