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...

Single crystals of KTb(C(2)O(4))(SO(4))(H(2)O), potassium aqua-terbium(III) oxalate sulfate, were obtained under hydro-thermal conditions. In the crystal structure, the Tb(III) atom is coordinated by four O atoms from two oxalate anions, three O atoms from three sulfate anions and one O atom from a water mol-ecule within a TbO(8) distorted square antiprismatic coordination. The potassium and te...

polyurethane foams are extensively used in different applications such as furnitures and sandwich structures due to better mechanical properties, higher acoustic and damping behavior, higher resistance to hydrocarbon, and aging.with respect to flammability of polyurethane materials and safety precaution in living and working environments there is a vital need to study and investigate published ...

Composite solid propellants were prepared with and without nano-alloys (Ti-Co, Ti-Ni, Ti-Zn), where nano-alloys used as catalyst. These nano-alloys are prepared by hydrazine reduction method. Catalytic properties of these nanomaterials were measured on Ammonium perchorate/hydroxyterminatedpolybutadiene propellant by thermogravimetery analysis and differential thermal analysis. Both experimental...

The title compound, [Ni(C(2)O(4))(C(5)H(5)N)(2)](n), was synthesized under hydro-(solvo)thermal conditions. The Ni(II) atom, lying on a twofold rotation axis, has an octa-hedral coordination geometry involving two N atoms from two pyridine ligands and four O atoms from two oxalate ligands. The Ni atoms are connected by the tetra-dentate bridging oxalate ligands into a one-dimensional zigzag chain.

Nano-structured vanadium oxide (V2O5) is fabricated via a facile thermal-decomposition of vanadium precursor, vanadyl oxalate, which is produced by reacting micro-sized V2O5 with oxalic acid. The V2O5 nanoparticles produced by this method exhibit much better electrochemical performance than commercial micro-sized V2O5. The optimized-nanorod electrodes give the best specific discharge capacities...
