“…The infrared spectra of these materials are shown in Figure 5. C-SAA has characteristic peaks at 3,313, 3,092, 1,644, 1,157, 1,075, 737, 609 and 479 cm −1 before adsorption, which corresponds to the absorption peaks at 3,296, 3,094, 1,640, 1,164, 1,071, 751, 630 and 484 cm −1 for γ-AlOOH (Bai et al, 2021) mentioned in the literature. The modified C-SAAoa material showed absorption peaks at 3,309, 3,095, 1,623, 1,167, 1,080, 743, 606 and 483 cm −1 .…”

C-SAAoa particles synthesized by simple and low-cost calcining industrial solid waste aluminium ash combined with waste oxalic acid modification process show excellent performance in fluoride removal speed and adsorption capacity. Their adsorption capacity on fluoride was determined at about 180.57 mg/g at pH 3.0, which was among the highest reported values in the literature. It was determined that the adsorption mechanism of fluoride on C-SAAoa particles followed mechanisms such as ion exchange, electrostatic action, and the surface - OH groups played a major role in the fluoride removal process. C-SAAoa particles can effectively remove fluoride, even in the presence of a certain concentration of competing anions. At the same time, the material possesses good cycling performance, and can still maintain 78.9% of the initial adsorption capacity in the longitudinal for eight recycles. Therefore, it may have the potential to become a promising adsorbent as a supplement to industrial solid waste resource-based utilization processes and also for fluoride removal in small-scale treatment facilities or wastewater with high fluoride concentrations.

“…First, spherical SiO 2 NPs were synthesized by an inverse microemulsion method (Figure 2b,c), [ 23 ] and then SiAl NPs were further synthesized through a hydrothermal method via adding aluminum nitrate in an alkaline environment ( Figure a). [ 24 ] Transmission electron microscopy (TEM) images revealed that the obtained SiAl NPs were hollow spherical structure with spike‐like aluminum hydroxide on the surface and their sizes were about 50 nm (Figure 1b,c, and Figure S1, Supporting Information). Moreover, its hydrated particle size measured by dynamic light scattering (DLS) was about 100 nm and no obvious change can be observed in PBS within 12 h (Figure S2a, Supporting Information).…”

also collected on days 15 for further studies when mice were sacrificed. Flow cytometry was used to analyze CD8 + T cells, CD4 + T cells, DCs, and memory T cells in splenocytes, respectively. Lungs were also collected for studying lung metastasis when mice were sacrificed on days 28.Statistical and Analysis: All experiments were performed with at least three replicates and results were expressed as mean ± S.D. ANOVA was used to assess statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. Graphpad Prism 7 was used for statistical analysis.

“…Both Al(OH) 3 and AlOOH have wide applications in industry. Al(OH) 3 is the most widely used inorganic flame retardant additive, and AlOOH is used in the fields of lithium battery separators, adsorption, and catalysis. , Furthermore, Al(OH) 3 and AlOOH can also be calcined at different temperatures to produce alumina with different crystal structures . Therefore, studying the formation mechanism of hydrolysates to facilitate their reuse is an important research direction for reducing the cost of the Al-H 2 O reaction.…”

Hydrogen production via Al-H 2 O reaction has potential uses in the fields of space thrusters, engines, and hydrogen fuel cells, where hydrogen production performance of Al-based composites is critical. In this study, low-cost active additives, including g-C 3 N 4 (CN) and NaCl were added to Al−In−Sn (AlIS) alloys by the mechanical ball milling method in order to substitute metal Ga and regulate the hydrogen production activity, as Ga not only increases the cost of Al-based materials but also adversely affects the recycling of products. The results demonstrate that both CN and NaCl additives can effectively enhance hydrogen production performance of AlIS in a single additive system. Further, when 5 wt % of CN and 2.5 wt % of NaCl are concurrently introduced, Al-based composites exhibit the highest hydrogen production efficiency of 94.45% at ambient temperature. The highest hydrogen production rate reaches 475 mL•s −1 •gAl −1 . Even at 2 °C, there is still 86.66% conversion efficiency. The hydrolysates of the Al-H 2 O reaction are composed of Al(OH) 3 and AlOOH, which are primarily influenced by the reaction temperature and the types of Al-based composites. The hydrolysate formation mechanism is analyzed and proposed.
