ZnO and TiO2 are semiconductor nanomaterials that widely used in photocatalysis. However, the relatively high recombination rate low quantum yield of photogenerated electron–hole pairs limit their practical applications. In this study, a series TiO2/ZnO/diatomite composites with various compositions were successfully prepared via two-step precipitation method. They exhibited stronger UV–visible...

Abstract Water absorption into cementitious materials has been discussed to be anomalous because of the nonlinearity cumulative water absorbed with square root time. In this study, characteristics in porous such as autoclaved aerated concrete (AAC), diatomite, and calcium silicate board were examined focusing on different pore structures gravity effect. The one‐dimensional diatomite both from t...

The method of micro-arc oxidation has been utilized to synthesize a protective biocompatible coating for bioresorbable orthopedic Mg implant. This paper presents the results comprehensive research coatings based on diatomite—a biogenic material consisting shells diatom microalgae. main focus this study was functionalization diatomite-based by incorporating particles titania (TiO2) into them. Va...

Petrological investigations of the sand fraction and of granuleto cobble-sized clasts in the Plio-Pleistocene sedimentary cycles of the AND-1B drill core at the NW edge of the Ross Ice Shelf (McMurdo Sound) highlight significant down-core modal and compositional variations. These variations provide: (i) direct information about potential source regions during both glacial maxima and minima; and...
