A new efficient and practical method for the room-temperature reduction of aromatic nitro compounds employing FeSO4. 7H2O, NaBH4, H3PW12O40 system in H2O under mild conditions is reported. The method is simple, inexpensive, ...

The main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. The obvious need for better knowledge in the ultra thin gate silicon dioxides, ...

Covalent grafting of MCM-41 with 3-chloropropyl trimethoxysilane and subsequent reaction respectively with acacdien and complexation with MoO2(acac)2 afforded MoO2acacdien@MCM-41. X-ray diffraction and nitrogen sorption ...

The fluid flow and heat transfer in lid-driven enclosures filled with Cu-water nanofluid is numerically investigated. The moving vertical walls of the enclosure  are maintained in a constant temperature, while the horizontal ...

As a new precursor, [tris(2-hydroxyacetophenato) triaqua(III)], [Y(HAP)3(H2O)3]; complex was used in thermal decomposition process for the synthesis of rod-like high-temperature ceramic YBCO with length of about 320-350 ...

The preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. The nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction ...

The silica supported platinum nanoparticles was synthesized by using the sol-gel method. The possibility of using diamminedinitro platinum (II) as Pt precursor and effect of metal precursor concentration on the final Pt ...

In this article, thermo-elastic-behavior of a thick-walled cylinder made from a polystyrene nanocomposite reinforced with functionally graded (FG) single-walled carbon nanotubes (SWCNTs) was carried out in radial direction ...
