Radioactive wastes often contain amorphous and crystalline phases, and vapor hydration can affect their durability. In this study, Cs-clinoptilolite was heated (at 1100 °C and for 2–36 h) to prepare the samples that were composed mainly of an amor

Three clinoptilolite-based materials, with Ba2+/NH4+ ratios of 2.27, 0.60 and 0.11, were prepared starting from a powder containing about 90% of NH4-clinoptilolite. The samples were submitted to thermal treatments of 2 h up to 1200 °C. Further treat

Helicobacter pylori can be found in the stomach of about half of the humans, and a large population can be associated with serious diseases. To survive in the stomach H. pylori increases the pH locally by producing ammonia which binds to H+ becoming

A powder containing about 90% of clinoptilolite in ammonium form, previously employed in a study concerning the thermal transformations of NH4-clinoptilolite, was used to prepare three samples with the following Cs+/NH4+ ratios: 0.51; 1.16; 5.00. The
