The corrosion behaviour of Al (6061)-B4C-Graphite was investigated. The Aluminium Metal Matrix Composites (AMMC) was fabricated through two step stir casting method. The composites were fabricated with various volume percentages of Boron Carbide (5, 10 &15%) and Graphite (5, 10& 15%). Corrosion studies of AMMC was inv…
Reorganization processes is base of social development. In every field of knowledge necessary have and use adequate models proper process and so its components. Consider base model of cycle reorganization, intercommunications between its components and expediency use procedure «illumination» of cycle.
This article deals with the issues of studying low-molecular-weight volatile organic compounds (VOCs) of aquatic macrophytes growing in Russia under different environmental conditions and geographic regions. It is shown that the composition of VOCs and their content depend on the abiotic (geographical location of habi…
Detection of Power Quality (PQ) is an essential service which many utilities perform for their industrial and large commercial customers. Poor PQ affect the load connected to the supply. It shortens the life of load and can damage the load. It is a difficult task to detect and classify electrical problems which can ca…
In this paper, a novel metamaterial filter based on frequency selective surface (FSS) is proposed. Using the mode matching method, we theoretically studied the transmission performance of the structure. Results show that, by rotating its neighboring elements 90 degree, the novel filter has a better stability to angle…
Abstract Hydrogel capsules show attractive prospects in drug delivery recently because of high drug loading and sustained release behavior. In this study we reported a simple and convenient route to fabricate poly (acrylic acid)-poly (N-isopropylacrylamide) (PAA-PNIPAm) hydrogel capsules by using hydroxypropylcellulos…
The area in apple production in Brazil exceeds 38,000 ha, with 'Gala' and 'Fuji' clones representing 90 percent of total production. Most of the region does not accumulate enough chilling to overcome dormancy on these two cultivars. Chemical induction of budbreak has been widely used in commercial apple production in…
Nanowire arrays exhibit efficient light coupling and strong light trapping, making them well suited to solar cell applications. The processes that contribute to their absorption are interrelated and highly dispersive, so the only current method of optimizing the absorption is by intensive numerical calculations. We pr…
Magnetic nanotubes (NTs) are interesting for magnetic memory and magnonic applications. We report magnetotransport experiments on individual 10 to 20 μm long Ni and CoFeB NTs with outer diameters ranging from 160 to 390 nm and film thicknesses of 20 to 40 nm. The anisotropic magnetoresistance (AMR) effect studied from…
High perpendicular magnetic anisotropy (PMA) has been recently revealed in CoFeB/MgO/CoFeB tunnel junctions if the thickness of CoFeB is2while MgO/CoFeB/Ru has a much weaker interface anisotropy constant ~0.68 erg/cm2. In addition, the magnetic dead layer (MDL) of MgO/CoFeB/cap (cap = Ta and Nb) is ~0.1 nm while MgO/C…
The synthesis of nanocrystals with high-energy facets is an important and challenging research topic. In this work, we develop a facile hydrothermal method to synthesize a nanocomposite of SnO2 octahedral nanocrystals (ONCs) exposed to high-energy {332} facets on graphene sheets (GS) as an advanced anode material for…
Molluscan shells are attracting research interest due to the diverse application properties possessed. As shells are very similar to bones, this study was conducted to analyze the mineral and physiochemical composition of Cockle (Anadara granosa) shell and three other types of molluscan shell, namely Strombus canarium…
Methanol is a versatile chemical feedstock, fuel source, and energy storage material. Many reactions involving methanol are catalyzed by transition metal surfaces, on which hydrogen-bonded methanol overlayers form. As with water, the structure of these overlayers is expected to depend on a delicate balance of hydrogen…
Use of the amorphous state is considered to be one of the most effective approaches for improving the dissolution and subsequent oral bioavailability of poorly water-soluble drugs. However as the amorphous state has much higher physical instability in comparison with its crystalline counterpart, stabilization of amorp…
constructional rearrangement is a special case of «Rearrangement» phase in reorganization cycle. It is a set of measures, works and solutions implemented to improve operating characteristics of a construction facility. The main goal of CR objects is to bring them to the condition meeting the needs of users or requirem…
Water-in-oil (w/o) microemulsions were used as a template for the synthesis of mono- and bi-metallic nanoparticles. For that purpose, w/o-microemulsions containing H2PtCl6, H2PtCl6 + Pb(NO3)2 and H2PtCl6 + Bi(NO)3, respectively, were mixed with a w/o-microemulsion containing the reducing agent, NaBH4. The results reve…
Plasmon coupling between noble metal nanoparticles has been known to dramatically enhance linear and nonlinear optical properties of nearby chromophores and metal nanoparticles themselves. The interparticle distance is expected to have significant influence on the coupling strength. Here we have prepared DNA tuned Au…
We demonstrate an electro-optic response that is linear in the amplitude but independent of the sign of the applied electric field. The symmetry-preserving linear electro-optic effect emerges at low applied electric fields in freezing nanodisordered KNTN above the dielectric peak temperature, deep into the nominal par…
The new compounds [Ru(acac)2(BIAN)], BIAN = bis(arylimino)acenaphthene (aryl = Ph (1a), 4-MeC6H4 (2a), 4-OMeC6H4 (3a), 4-ClC6H4 (4a), 4-NO2C6H4 (5a)), were synthesized and structurally, electrochemically, spectroscopically, and computationally characterized. The α-diimine sections of the compounds exhibit intrachelate…
In this study, a four-stroke, naturally aspirated, single-cylinder, spark ignition engine was operated with neat gasoline fuel. In-cylinder pressure, performance, and emission values were obtained at full load and 2400-r/min constant engine speed. Using these values, a single-dimensional theoretical model was calibrat…
