Introduction: There is a growing interest in the study of sulfate minerals on the surface of Mars, supported by the discovery of jarosite at Meridiani Planum [1-3]. There is also the possibility of finding hydrous sulfate minerals in the permafrost, located at the polar regions. Sulfate minerals often precipitate in a variety of hydration states in the presence of liquid water. The spectra of s...

Increasing evidence in both experimental and clinical studies suggests that oxidative stress plays a major role in the pathogenesis of both types of diabetes mellitus. The disease is also known to adversely affect some haematological parameters and cause dyslipidemia. This study was designed to investigate the effect of chronic administration of ethanolic leave extract of Senna fistula on haema...

-A stable 8.4/~ hydrate of kaolinite was prepared by exchanging ethylene glycol for water in the 10.8 A intercalate of ethylene glycol in kaolinite. The hydrate of kaolinite was characterized by XRD, FTIR and TGA/DSC. From the TGA data, one can estimate that there is 0.60 water molecule per A12Si20~(OH)4 units. The IR data suggest a similarity of the local environment of the intercalated water ...
