Ammonia sensors based on catalytic oxides such as V2O5, MoO3 and α, β- and γ-bismuth molybdates have been investigated. MoO3 (15 mo1%) supported on TiO2 and γ-Bi2MoO6 both exhibit satisfactory sensing characteristics for ...

In-situ EXAFS studies have been carried out on several transition metal (T)-MoS2 (T = Fe, Co, Ni or Cu) catalysts supported on γ-Al2O3. While Mo is present in small crystallites of MoS2 in all the systems studied, the local ...

Field-effect transistor characteristics of few-layer graphenes prepared by several methods have been investigated in comparison with those of single-layer graphene prepared by the in situ reduction of single-layer graphene ...

The structure of Fe(Phen)(2)(NCS)(2) has been examined across the first-order spin-state transition by EXAFS with full multiple scattering analysis. The EXAFS data at 298 K can be satisfactorily assigned to the high-spin ...

Two new open-framework tin(II) phosphate materials have been synthesized hydrothermally and their structures elucidated by single-crystal X-ray diffraction. These materials exhibit an entirely new building motif, unknown ...

The nature of diamond-graphite hybrids has been studied by molecular mechanics, by examining the structures of species such as C84Hx wherein the sp(3) to sp(2) carbon ratio is varied progressively. The dependence of the ...

A careful investigation of the structures and charge densities of the beta and alpha polymorphs of p-nitrophenol has been carried out. Although the two forms crystallize in different monoclinic cells, the crystal densities ...

Multi-walled, single-walled and double-walled carbon nanotubes as well as graphene can be doped with boron and nitrogen. B2H6 has been generally used as the boron source while NH3 or pyridine is employed as the nitrogen ...

Scanning tunneling microscopy of solid films of C-60 and C-70 clearly demonstrate the occurrence of photochemical polymerization of these fullerenes in the solid state. X-ray diffraction studies show that such a polymerization ...
