Among the CaCO<sub>3</sub> polymorphs, aragonite demonstrates a better performance as a filler material in the paper and plastic industries. Despite being ideal from the environmental protection perspective, the production of aragonite particles via CO<sub>2</sub> mineralization of rocks is hindered by the difficulty in achieving high production efficiencies and purities, which, however, can be mitigated by exploiting the potential ability of chelating agents on metal ions extraction and carbona
The construction of high-performance bifunctional self-supported electrodes is significant for promoting the activity and stability of water splitting. The self-supported electrode not only has a strong structural characterization but also avoids the negative effects of using binders. Herein, we fabricated a self-supported electrode (Ni2P/MoP@CNTs-CC), which is composed of carbon nanotubes (CNTs) directly grown on carbon cloth (CC) filled with transition metal-based phosphide composite nanoparti
Phosphorus, an essential rare element in aquatic ecosystems, plays a key role in maintaining ecosystem balance. However, excess phosphorus leads to eutrophication and algal proliferation. To prevent eutrophication, the pretreatment and measuring of the concentration of total phosphorus (TP) is crucial. Compared to conventional TP pretreatment equipment (autoclave), a lab-on-a-chip detection device fabricated using micro-electromechanical system technology and titania (TiO2) as a photocatalyst is

In this paper, the melt-spun ZrwAl7SCu27.5 amorphous alloy, a typical bulk metallic glass with high glass ability, was used to braze a TiAl-based alloy. The mierostructure and elements distribution have been studied. The results show that the Zr65AI7.5Cu27.5 amorphous ribbons can successfully braze the TiAl-based alloy. Layered structures appear in the brazing seam. From the middle region to the interface region of the brazing seam, the miorestures are the Zr2Cu-type and ZrCu precipitates,the co
