Abstract

A new species of the genus Pinctada is described from samples collected from the east coast of Phuket Island, Thailand in the Andaman Sea. Pinctada phuketensis sp. nov. is distinguished from other species on both molecular and morphological data. Morphologically, the valves of P. phuketensis are characterized by a slightly developed to undeveloped posterior auricle, a small, narrow slit-like byssal notch, the absence of hinge teeth, and a pale to transparent non-nacreous border, with a few dark brown or red blotches. This new species resembles P. fucata but differs by its smaller size and the absence of hinge teeth. Phylogenetic analyses based on both mitochondrial (COI) and nuclear (18S rDNA, ITS1 and ITS2) genes and species delimitation using COI data strongly support that P. phuketensis is a distinct species, which is closely related to Pinctada albina and Pinctada nigra.

Abstract

Hydrogen peroxide is an important reactive oxygen species (ROS) that acts as a significant marker of oxidative stress in certain diseases. Owing to the autofluorescence of biological samples, H2O2 monitoring remains challenging. Here, Si‐CdTe quantum dots (QDs) are prepared as novel ratiometric fluorescent probes prepared for sensitive detection of H2O2 and glucose, the low detection limit of H2O2 and glucose is 79 and 140 nm, respectively. In this article, CdTe QDs are combined with Si QDs to reduce the cytotoxicity of CdTe. The survival rate of HeLa cells remains at 80% after incubation with the Si‐CdTe QDs at a concentration of 500 µg mL−1 for 24 h. Fluorescence extinguishes based on 488 and 514 nm channels are used as internal references to avoid environmental interference and demonstrate selective H2O2 biosensing. In addition, the probe has an excellent colocalization effect in the lysosome under the 514 nm channel, with a maximum Pearson coefficient of 0.96. The advantages of easy preparation, low toxicity, high resistance to photobleaching, and high specificity of the Si‐CdTe QDs probes provide a new and convenient means to monitor and detect changes in the endogenous intracellular H2O2 concentration and to select 514 nm lysosomal colocalization dyes.

Abstract

Molecule-like electrocatalysts with FeN4motifs have been demonstrated to be excellent candidates for various renewable energy conversions. The ability to further tune the electronic properties of molecular FeN4motifs and integrate them onto conductive supports represents a key step towards the synthesis of highly robust and efficient single-atom catalysts (SACs) for practical applications. Here, we developed a new route for the synthesis of a well-defined single-atom FeN4electrocatalystvia in situpolymerization of four amino groups functionalized iron phthalocyanine (NH2-FePc) molecules on conductive carbon nanotubes. The intermolecular oxidative dimerization between the amino groups of NH2-FePc creates the desired electron-withdrawing pyrazine linker between FeN4motifs, which can significantly optimize their electrocatalytic performances. As a result, the FeN4-SAC exhibits both outstanding ORR activity (a half-wave potential of 0.88 Vvs.RHE) and excellent performance in Zn-oxygen batteries, outperforming the commercial Pt/C and pristine iron phthalocyanine (FePc) catalysts. Our theoretical calculations reveal that the presence of electron-withdrawing linkers shifts the occupied antibonding states towards lower energies and thus weakens the Fe-O bond, which is primarily responsible for the enhancement of ORR activity.
