In this study, a new hydrophilic-hydrophobic transition surface was designed via visible-light-induced photocatalytic perfluorinated silica-based fluorescent carbon nanoparticles (FNPs)/TiO2. Perfluorinated silica-polydopamine hybrid FNPs (f-FNPs) were easily fabricated by carbonization in an emulsion system consisting of tetraethyl orthosilicate and(More)
In eggs of oviparous reptiles, fetal membranes maintain developing embryos through the exchange of respiratory gases and provision of water and calcium. As part of a survey of reptilian fetal membranes, we used scanning electron microscopy to study fetal membrane morphology in the oviparous Pueblan milksnake, Lampropeltis triangulum campbelli. The(More)
In this communication, we present a new synthesis method for the fabrication of hybrid metal-Cu2S (M = Pt, FePt) nanocrystals (HNs). The metal-Cu2S HNs were investigated in photocatalytic hydrogen generation as effective co-catalysts on TiO2. The Pt-Cu2S/TiO2 catalyst showed a higher hydrogen generation rate compared with a pure TiO2 catalyst. This(More)
In reptilian sauropsids, fetal (extraembryonic) membranes that line the eggshell sustain developing embryos by providing for gas exchange and uptake of water and eggshell calcium. However, a scarcity of morphological studies hinders an understanding of functional specializations and their evolution. In kingsnakes (Lampropeltis getula), scanning electron(More)
