Exploring the intrinsic mechanisms of rare-earth ions entering the crystal phase has great significance for finely tuning the luminescent properties of glass-ceramics. Using Er ions as a probe, X-ray diffraction was employed to precisely measure the crystallinity of SiO-PbF-ErO glass-ceramics synthesized under various heat treatment conditions, confirming the occurrence of a rapid crystallization process. Additionally, by combining Judd-Ofelt theory with comprehensive analyses of absorption and fluorescence spectra, we calculated the relative proportions of Er ions present in the crystal phase. We found that the crystallization process in the glass-ceramics and the incorporation of Er ions into the crystal phase did not occur synchronously. This discovery provides new theoretical foundations and practical guidance for understanding the mechanism of rare-earth ion incorporation into crystal phases, which is significant for the development of functional materials with specific luminescent properties.

Collaborative stabilizing effect of trehalose and myofibrillar protein on high internal phase emulsions: Improved freeze-thaw stability and 3D printability.

This study investigated the improvement of adding trehalose (Tre) on freeze-thaw (F-T) stability and 3D printability of myofibrillar protein (MP)-based high internal phase emulsions (HIPEs), also the underlying mechanism. Appropriate Tre addition formed thicker shell-like structure around MP by hydrogen bonds, and induced protein unfolding to ameliorate amphiphilicity. Additionally, Tre promoted the MP diffusion to interface to reduce interfacial tension.

At present, the mechanism difference between tetragonal BiVO (t-BiVO) and monoclinic BiVO (m-BiVO) coupled peroxymonosulfate (PMS) to realize photocatalysis is still unclear. In this study, m-BiVO and t-BiVO were obtained by adjusting the bismuth-vanadium ratio in the precursor solution (Bi:V=3:1; 1:1; 1:2 and 1:3). The results of photocatalytic experiments showed that both t-BiVO and m-BiVO had certain activation effects on PMS, and the prepared monoclinic B1V2 has the strongest photocatalytic performance.

Activated alumina-based composite oxide support is a commonly used support in hydrodesulfurization (HDS) catalysts, which not only retains the performance advantages of each component in the composite oxide support, but also significantly improves the defects of a single activated alumina support, such as the strong metal-support force of interaction. In this study, NiO-AlO composite support was prepared by introducing NiO-modified AlO, and MoS/NiO-AlO catalysts were prepared for the hydrodesulfurization of COS by liquid phase reduction method. In the COS hydrogenation reaction, the MoS/NiO-AlO catalyst achieved complete conversion of COS at 220 °C and showed more than 99.

Particulate matters (PMs), one of the major airborne pollutants, continue to seriously threaten human health and the environment. Here, a self-crystal-induced electret enhancement (SCIEE) strategy was developed to promote the in-situ electret effect and polarization properties of electrospun poly(L-lactic acid) (PLLA) nanofibers. The strategy specifically involved the elaborate pre-structuring of stereocomplex crystals (SCs) with uniform dimensions (∼300 nm), which were introduced into PLLA electrospinning solution as the electrets and physical cross-linking points of high density.
