One-Pot Hydrothermal Synthesis of g-C₃N₄/BiPO₄ Nanocomposites with Significant Photocatalytic Activity.

The g-C₃N₄/BiPO₄ composites have been successfully synthesized via a one-pot hydrothermal process, which can be used to degrade the organic dyes (rhodamine B and methylene blue) under simulated sunlight irradiation. X-ray diffraction (XRD), scanning electron microscope (SEM), UV-Vis diffuse reflectance spectra and Fourier transform infrared (FTIR) spectroscopy have been employed to characterize the samples. The g-C₃N₄/BiPO₄ composites exhibited higher photocatalytic activity than pure BiPO4.

Formation of CO bubbles in epoxy resin coatings: A DFT study.

The epoxy resin coating is a fundamental species with epoxy resins used as main components to form the final film. Unexpectedly, bulky CO bubbles that occasionally appeared during the curing process of epoxy resin coatings might destroy the final film properties. With an attempt to thoroughly understand the formation mechanism of CO bubbles and further propose countermeasures to control them, Density Function Theory (DFT) in this paper was employed to calculate the absorption process, the curing reaction and the formation mechanism of CO bubbles.

A novel ratiometric fluorescent sensor for Ag+ based on two fluorophores.

A novel ratiometric fluorescent probe BCB was reported for the first time for the sensitive and selective analysis of Ag based on two Boradiazaindacene (BODIPY) as both the reference fluorophore and recognition part. Upon the addition of Ag ions, a strong fluorescence emission at 570 nm from recognition BODIPY would be appeared, whereas the fluorescence of the other BODIPY at 535 nm would be a constant reference fluorescence signal. As a result, the ratio of fluorescence intensity (λ570/λ535) was changed from 0.
