In this paper, Cu and Ce were added to melt-spun Al-Ag precursor alloys to refine the microstructures of nanoporous Ag and Ag/CeO2 composite catalysts for NaBH4 oxidation. After the precursor alloys were dealloyed in 20% NaOH, calcined in air and corroded again in 50% NaOH, Ag2Al in the precursor alloys was completely removed, and refined…[Read more]

Predator recovery driven by single-species management approaches may lead to conservation conflicts between recovered predators and prey species of conservation concern. As part of an aggressive recovery plan, the Eastern Peregrine Falcon Recovery Team released (1975-1985) 307 captive-reared peregrine falcons (Falco peregrinus) and successfully…[Read more]

To synthesize and characterize a novel resin-based dental material containing 3-aminopropyltriethoxysilane (APTES) surface-modified halloysite-clay nanotubes (HNTs) for long-term delivery of guest molecules.

The optimal concentrations of HNT (10, 15, 20 wt.%) and silane (0, 2, 4 vol.%sil) to be incorporated into the resin-based materials…[Read more]

Vitex megapotamica (Spreng.) Moldenke is a plant with medicinal properties popularly used in Brazil to treat diabetes and obesity. Despite the promising use of this plant, are still incipient toxicology studies on prolonged periods of treatment. The aim of this study was to evaluate the repeated dose 90-day oral toxicity study of V. megapotamica…[Read more]
