In this paper, the hot compressive deformation characteristics of a Mg–10Gd–3Y–0.5Zr (GW103K) alloy have been investigated by isothermal compression test at the temperature range of 350–450°C and strain rate range of 0.0001–0.1s −1 . True stress–strain relationships at various strain rates showed the typical strain ha…
We report on the design and results of the second reactive synthesis competition (SYNTCOMP 2015). We describe our extended benchmark library, with 6 completely new sets of benchmarks, and additional challenging instances for 4 of the benchmark sets that were already used in SYNTCOMP 2014. To enhance the analysis of ex…
It was studied the green synthesis of silver nanoparticles (AgNPs) from the reduction of a silver nitrate solution (1 and 10mM) in the presence of an extract of mangifera indica leaves. Phytochemicals components present in extracts of mango leaves were determined using a GC-MS chromatograph. The results showed the pre…
Abstract The preparation and characterization of high‐energy density hydrocarbon fuel JP‐10 supramolecular gel propellants are reported. The low‐molecular mass gelator 1,1′,1′′‐((2,4,6‐trioxo‐1,3,5‐triazinane‐1,3,5‐triyl)tris(hexane‐6,1‐diyl))tris(3‐octadecylurea) (HDIT‐18) shows powerful gelation ability for JP‐10, t…
Electrospun nanofibrous materials are widely used in medical applications such as tissue engineering scaffolds, wound dressing material and drug delivery carriers. For tissue engineering scaffolds, the structure of the nanofiber is similar to extracellular matrix (ECM) which promotes the cell growth and proliferation.…
This paper processed and characterized cost-fewer polypropylene (PP) nanocomposite films; an experimental work has been investigated for studying the electric properties of the new nanocomposite materials and compared with unfilled industrial materials in a frequency range up to 1 kHz. A small addition of nanoparticle…
A systematic study on the degradation and mechanism of composite materials based on polybutylenes succinate/ polycaprolactone (PBS/PCL) was conducted by putting composites of different ratios into the local soil culture solution and cured compost culture solution to observe the microbial reaction. The surface morpholo…
This paper reviews the thermal conductivity (TC) enhancement of transparent and flexible polymer composites. Poly-dimethyl siloxane (PDMS), polyethylene terephthalate (PET), and polyimides (PI) are considered. The physical properties of these polymers reinforced with many highly conductive fillers have been investigat…
In this paper we show the characterization of two kinds of quantum dots: hydrophilic and hydrophobic, with core and core/shell respectively, using spectroscopy techniques such as UV-Vis, fluorescence and Raman. We determined the quantum yield in the quantum dots using the quinine sulphate as standard. This salt is com…
In the present work hybrid sol-gel coatings were synthesized on different magnesium alloys with potential interest in the fabrication of orthopaedic implants. Hybrid sols were obtained from a mixture of the inorganic precursor tetraethoxysilane (TEOS) and the organic precursor 3-glycidoxypropyltrimethoxysilane (GPTMS)…
This study describes an improved method used to determine the dynamic shear failure of materials under blast loading conditions. The proposed method is a convenient and effective and generates material failure along the controlled fracture trajectories under uniform uniaxial stress conditions at a strain rate of [Form…
The chemical shifts from the protons belonging to surfactants differing only by the nature of counterions (Li, Na, Cs) are considered in their interaction with the surface of carbon nanotubes. It was shown that the dominant mechanisms of interaction of the surfactant molecules with the nanotubes surface in aqueous sol…
Tuning the lattice strain (εL) is a novel approach to manipulate the magnetic, electronic, and transport properties of spintronic materials. Achievable εL in thin film samples induced by traditional ferroelectric or flexible substrates is usually volatile and well below 1%. Such limits in the tuning capability cannot…
It is shown that phagraphene, a recently predicted planar allotropic form of graphene with Dirac fermions, is unstable or, at least, almost unstable with respect to transverse atomic displacements in the monolayer. This result is obtained by numerical calculations in the framework of both the tight-binding model and t…
Resistance to electrical tree-induced degradation is one of the common ways of characterising solid dielectrics. This paper presents experimentally obtained distinct time-evolution patterns of electrical tree partial discharges (PDs) in epoxy nanocomposites of Magnesia, Silica and Alumina. Plots of the electrical tree…
Spiders are famous for their silk with fascinating mechanical properties. However, some can further produce, process and handle nano fibres, which are used as capture threads. These 'cribellate spiders' bear a specialized setae comb on their metatarsus (calamistrum), which modifies cribellate nano fibres to assemble a…
We study secondary electron yield (SEY) suppression of silver using a hyperbranched nanostructure obtained by thermal evaporation. First, we perform thermal evaporation at different residual gas pressures for studying the influence of pressure on surface morphologies. A self-assembled hyperbranched Ag nanostructure ha…
In this paper, we report the design, analysis, and simulation of the low-frequency perfect metamaterial absorber (MMA) based on corrugated surface, which has very small unit-cell size. The proposed MMA consist of a regular square-array and a metallic background plane, separated by a corrugated surface with periodic sq…
The experimental data on the temperature dependence of the four transport coefficients, i.e., the electrical conductivity (σ), Hall coefficient (RH), Seebeck coefficient (S), and Nernst coefficient (Q), of n-type Co0.999Ni0.001Sb3 reported by Sun et al. [Nat. Commun. 6, 7475 (2015)] have been analyzed in a multi-band…
A nano-liposomal carrier was prepared for the anti-inflammatory drug prednisolone acetate (PA). The drug showed remarkable loading in the nano-carriers. The drug-loaded nano-liposmes with average sizes of about 186 nm and zeta potentials of −20 mV were obtained. Our drug release studies showed an apparently zero-order…
