Understanding the processes controlling chemical sedimentation is an important step in deciphering paleoclimatic conditions from the rock records preserved on both Earth and Mars. Clear evidence for s...
The in vitro antifungal effect of the essential oil of Citrus medica L. on storage fungi of Arachis hypogea L. stored for 6 months was evaluated using the disc diffusion agar method. The oil exhibited...
A white calcium bentonite (CaB) from the K\"{u}tahya region/Turkey was activated by heating it for 6 hours at 97°C in H2SO4 solution. The mass percentage of H2SO4 in the bentonite-acid mixture was var...
In order to prepare fine alumina powders, an emulsion was prepared under optimum conditions. The emulsion was examined by optical microscopy and the prepared fine alumina powders were characterised by...
Abstract: A white calcium bentonite (CaB) from the Kütahya region, Turkey, contains 35 wt. % opal-CT and 65 wt. % Ca-rich montmorillonite (CaM). Samples were heated at various temperatures between 100...
The influence of tartaric acid and pH on chemical composition, morphology, surface area, and porosity of short-range ordered Al precipitation products was studied. Samples were prepared (1) at pH 8.0 ...
The surface charges and the zeta potential of a Na-montmorillonite (Na-mont) and two pillared montmorillonite (MP1 and MP2) samples with different aluminum contents were determined by potentiometric t...
Abstract: By ion exchanging expandable clay minerals with large, cationic oxyaluminum polymers, 損illars?were introduced that permanently prop open the clay layers. On the basis of thermal, infrared sp...
