Overview: Stability experiments indicate that amorphous sulfate phases may be important constituents of martian surface materials [1-2]; there is also considerable spectral evidence for non-crystalline sulfate phases on Europa [3-4]. However, the thermal infrared (TIR) and near-infrared (NIR) spectral characteristics of these phases are largely unknown. X-ray amorphous Mg-and Fe-sulfate phases ...

We report herein studies on the liquid crystalline behavior of a series of supramolecular materials that contain different ratios of two complementary symmetrically-substituted alkoxy-bis(phenylethynyl)benzene AAand BB-type monomers. One monomer has thymine units placed at either end of the rigid mesogenic core, while the other has N-(4-methoxybenzoyl)-adenine units placed on the ends. Differen...

Sol–gel chemistry is a versatile synthesis used to produce modern materials at near-room temperature [...]

Glass crystalline materials (GCM) are of increasing interest as advanced nuclear wasteforms combining the advantages vitreous and matrices. The GCM versatile envisaged for a wider use to immobilise various types both radioactive chemically hazardous wastes. They can be produced either via low temperature sintering using precursors composed glass frit, oxides, phases or through conventional melt...
