Since the end of the last century, the discovery of polymer nanocomposites and their ever-
expanding use in various applications has been the result of continuous developments in …

Surface hydroxyl groups are active centers in many catalytic reactions and can play an
important role during catalyst preparation. In this chapter, the application of infrared …

This paper reviews different methods to synthesise zeolite from clay minerals through
experiments at a low incubation temperature (40° C). Ca-montmorillonite, Na …

Acid activation is a chemical treatment traditionally used on clays, typically bentonites in
hydrochloric or sulphuric acid, to obtain partly dissolved materials with enhanced surface …

Columbus crater in the Terra Sirenum region of the Martian southern highlands contains
light‐toned layered deposits with interbedded sulfate and phyllosilicate minerals, a rare …

Acid activation is a common chemical modification of clays, usually bentonites, with a hot
solution of a mineral acid (typically HCl or H 2 SO 4), and it is used for both scientific and …

Slovak bentonite was used as an effective natural adsorbent for the removal of Cd (II) and
Co (II). Characterization of the samples was conducted using X-ray diffraction (XRD), high …

Phyllosilicate deposits on Mars provide an opportunity to evaluate aqueous activity and the
possibility that habitable environments may have existed during the Noachian period there …

Analyses of MRO/CRISM images of the greater Mawrth Vallis region of Mars affirm the
presence of two primary phyllosilicate assemblages throughout a region∼ 1000× 1000 km …

A cryoconite granule is a biologically active aggregation of microorganisms, mineral
particles and organic matter found on glacier surfaces, often within shallow pools or …
