Although theoretical calculations have predicted that layered GaS and GaSe should form nanotube and related structures, they have not been prepared experimentally to date. We have carried out laser irradiation as well as ...

We have investigated the specific heat and resistivity of a single crystal of Pr0.63Ca0.37MnO3 around the charge ordering (CO) transition temperature, T-CO, in the presence of high magnetic fields (less than or equal to12 ...

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 ...
