The present investigation reported the controlled synthesis of Cd0.9Zn0.1S and Cd0.89Zn0.1Ni0.01S nanostructures by simple chemical co-precipitation route. XRD analysis confirmed cubic structure CdS on Zn doped Zn, Ni dual without any secondary/impurity phases no alteration in phase was noticed Zn/Ni addition. shrinkage crystallite size from 69 to 43 Å variation lattice constants micro-strain w...

magnesium hydroxide nanostructures as an effective flame retardant were synthesized by a facile and rapid microwave reaction. the effect of different surfactants such as cationic, anionic and polymeric on the morphology of magnesium hydroxide nanostructures was investigated. nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform in...

NOx emissions in the atmosphere can cause various environmental problems, which should be strictly controlled and regulated. Furthermore, because of limited amount crude oil resources world severe global warming, development fuel-efficient vehicles has long been desired. Accordingly, efficient storage reduction catalysts have developed over decades, called NSR (NOx storage/reduction) catalysts....

We report the preparation, oxygen reduction reaction (ORR) electrocatalytic activity, and structural transformation of Pt–Ni nanowires (NWs) during potential cycles in presence absence nanoparticles (NPs). The ORR activity NWs increases over 25000 NPs, involving to branched nanostructures assisted by Ostwald ripening NPs. This is coupled with surface electronic change, as confirmed situ X-ray a...

Ultrafast demagnetization induced by femtosecond laser pulses in thin metallic layers is caused the outflow of spin-polarized hot-electron currents describable superdiffusive transport model. These laser-generated spin can cross interface into another magnetic layer and give rise to magnetization dynamics valves with noncollinear magnetizations. To describe ultrafast such nanostructures, we dev...

tm3+, yb3+ and tm3+/yb3+ doped lavo4 nanostructures were synthe-sized for the first time by using the hydrothermal method with the aid of la(ch3co2)3 as  lanthanum source in presence of oleic acid as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), photoluminescence (pl) spectroscopy and uv–vis di...
