Biominerals and biomaterials with unique microstructure are mainly consisted of organic and inorganic materials, and exhibit excellent biological and mechanical properties. The formation mechanism of biomineral indicated that the organic matrixes have an important influence on the morphology and structure of the inorganic matrix material in the process of biomineralization. However, the biomine...

Abstract Geopolymer (GP) has recently emerged as a novel and environmental friendly alternative to conventional soil stabilization products like lime Ordinary Portland Cement (OPC), which adversely affect the environment. This article emphasizes GPs produced from high calcium class C fly ash (CFA) an alkali activator comprising sodium hydroxide silicate solution for sand stabilization. The expe...

BACKGROUND Calcium silicate-based cements are biomaterials with calcium oxide and carbonate filler additives. Their properties are close to those of dentin, making them useful in restorative dentistry and endodontics. The aim of this study was to evaluate the in vitro biological effects of two such calcium silicate cements, Biodentine (BD) and Bioroot (BR), on dental stem cells in both direct a...

The aim of this study was to investigate the effects of solid carriers and processing routes on the properties of amorphous solid dispersions of itraconazole. Three solid carriers with a range of surface properties were studied, (1) a mesoporous silicate, magnesium aluminum silicate (Neusilin US2), (2) a nonporous silicate of corresponding composition (Veegum) and (3) a non-silicate, inorganic ...

In vitro dose responses of several calcium and potassium salts were determined on some commercially significant plant pathogens, including: Helminthosporium solani, Fusarium oxysporum f. sp. pisi race 2, Colletotricum coccodes, Phytophthora cactorum, Phytophthora cinnamomi, Phytophthora erythroseptica, Phytophthora infestans, Phytophthora megasperma, Pythium ultimum, and Venturia inaequalis. My...

This study compared the fluid filtration, adaptation to the root canal walls, and the push-out bond strength of two resin-based sealers and three calcium silicate-based retrograde filling materials. Fifty maxillary canines were shaped using manual instruments and the apical portion was sectioned. Retrograde cavities of 3-mm depth were prepared. The specimens were divided into five groups (n = 1...

Cement is the most widely used material for construction. However, the cement production has a negative impact on the environment, as it is one of the contributors to global warming. The production of one ton of cement also produces approximately one ton of CO2. This encourages to the search for more environmentally friendly materials as cement replacement. The aims of this study are to compare...
