The growth of gold nanocrystals prepared by the reduction of tetra-chloroauric acid by tetrakis(hydroxymethyl)phosphonium chloride, which allows slow reduction, is investigated by small-angle X-ray scattering and isothermal ...

Transition metal oxides, such as the mixed-valent rare-earth manganites Ln((1-x))A(x)MnO(3) (Ln, rare-earth ion, and A, alkaline-earth ion), show a variety of electronic orders with spatially correlated charge, spin and ...

For the preparation of novel organogel-carbon nanotube nanocomposites, pristine single-walled carbon nanotubes (SWNT) were incorporated into physical gels formed by an L-alanine based low molecular mass organogelator (LMOG). ...

A lead 2,6-dihydroxybenzoate of the formula Pb(C14H10O8) (I) has been synthesized and characterized by X-ray crystallography and spectroscopic techniques. (crystal data: monoclinic, space group = Cc (no. 9), a = 11.2155(2), ...

Organically templated metal sulfates are relatively new. Six aminetemplated transition-metal sulfates with different types of chain structures, including a novel iron sulfate with a chain structure corresponding to one ...

In situ Raman experiments together with transport measurements have been carried out on carbon nanotubes as a function of gate voltage. In metallic tubes, a large increase in the Raman frequency of the G(-) band, accompanied ...

Ammonia sensing characteristics of nanoparticles as well as nanorods of ZnO, In2O3 and SnO2 have been investigated over a wide range of concentrations ( 1-800 ppm) and temperatures ( 100-300 degrees C). The best values of ...

Graphenes prepared by three different methods have been investigated as electrode materials in electrochemical supercapacitors. The samples prepared by exfoliation of graphitic oxide and by the transformation of nanodiamond ...

ReO3 nanoparticles in the diameter range of 8.5-32.5 nm have been prepared by decomposition of the Re2O7-dioxane complex under solvothermal conditions and characterized by X-ray diffraction, electron microscopy, optical ...

The reaction of aliphatic alcohols such as methanol, ethanol and t-butanol with zinc powder at 330 degrees C under solvothermal conditions produces ZnO nanoparticles. The reaction involves the cleavage of the C-O bond of ...
