In this paper the feasibility of NbAl3/Al2O3 nanocomposite formation through mechanochemical reaction between Al and Nb2O5 and the effect of mechanical activation on the kinetic and reaction mechanism were investigated. Structural and phase evolution during mechanical alloying were studied by employing transmission electron microscopy (TEM)...

  Two facile and low cost routes were used for the synthesis of IF-WS2 nanoparticles. In this paper, preparation of IF-WS2 nanoparticles with two different methods was investigated. In the first method, WO3 nanopa...

Context. The occurrence rate of observed sub-Neptunes has a break at 0.1 au, which is often attributed to migration trap the inner rim protoplanetary disks where positive co-rotation torque prevents inward migration. Aims. We argue that conditions in disk regions are such likely open gaps, lose support as their become depleted, and trapping efficiency then becomes uncertain. study what it takes...

The effect of matric suction on S-wave velocity (V s ) unsaturated soils has been observed to show different trends from the Vs relationship with effective confining pressure. In some soils, increase in per unit stress change (u a -u w is greater than pressure (σ’3) for saturated and dry vice versa other soils. this study, difference was examined through state variables similar soil samples. Ex...

Generalized frames are an extension of frames in Hilbert  spaces and  Hilbert $C^*$-modules. In this paper, the concept ''Similar" for modular $g$-frames is introduced and all of operator duals (ordinary duals) of similar $g$-frames with respect to each other are characterized. Also, an operator dual of a given $g$-frame is studied where $g$-frame is constructed by a primary $g$-frame and an or...
