MoSe2 and WSe2 nanotubes are obtained by the reduction of the corresponding triselenides in hydrogen or by the decomposition of the ammonium selenometallates in a hydrogen atmosphere.

A hierarchy of novel zinc oxalates including monomers and dimers has been prepared by reaction of amine oxalates with zinc ions, the amine oxalates having been characterized for the first time. In most of the amine oxalates ...

Y-junction carbon nanotubes can be produced in relatively large quantities by the vapor phase pyrolysis of a mixture of cobaltocene or ferrocene with thiophene in a hydrogen atmosphere. Pyrolysis of Ni- and Fe-phthalocyanines ...

Chemistry creates both agony and hope in less-developed countries — although it may provide solutions to many of the problems faced there, the lack of expertise and poor infrastructure renders research extremely difficult. ...

We briefly describe the structures of open-framework metal phosphates with different dimensionalities, such as the one-dimensional linear-chain and ladder structures, two-dimensional layer structures and three-dimensional ...

An open-framework phosphate oxalate of zinc, of composition [NH3(CH2)(3)NH3][Zn-6(PO4)(4)(C2O4)], 1, has been synthesized, for the first time, employing hydrothermal methods in the presence of ethylenediamine. The structure ...

Four unusual inorganic-organic nanocomposites containing extended alkali halide structures, present as layers or as three-dimensional units, have been synthesized by a metathetic reaction carried out under hydrothermal ...

The first time-resolved in situ X-ray diffraction studies of the hydrothermal crystallisation of open-framework zinc phosphates reveal a pathway of sequential crystallisation involving formation of a metastable low dimensional ...

An experimental charge density investigation of 7,7-di[(S)-(+)-2-(methoxymethyl)pyrrolidino]-8,8-dicyanoquinodimethane establishes the presence of a large charge separation as well as a high in-crystal dipole moment compared ...

We report electron paramagnetic resonance measurements on single crystalline and powder samples of Nd0.5Ca0.5MnO3 across the charge-ordering transition at Tco=240 K down to the antiferromagnetic ordering transition at ...
