Summary: In this study, a dual self-healing and anti-freezing hydrogel was developed using functionalized microcapsules and phytic acid. The strong hydrogen bonds between phytic acid and water effectively lowered the freezing point of the hydrogel, allowing it to remain flexible at low temperatures. Additionally, the hydrogel showed high self-healing efficiency, making it suitable for low-temperature flexible sensors.

Summary: Red mud has great potential for producing low-carbon concrete as a supplementary cementitious material. However, its high alkalinity may induce alkali-aggregate reaction, so acids are commonly used for neutralization. Additionally, phytic acid is not suitable for direct application in reinforced concrete as an organic corrosion inhibitor. Therefore, a novel low-carbon and corrosion-resistant concrete was designed using both red mud and phytic acid, and a synergistic inhibition mechanism of the two was proposed based on the formation of a bilayer phytic acid-related protective film on the steel surface.

Summary: This review provides an overview of the role of phytic acid in the binding, solubility and bioavailability of iron, zinc and calcium in legumes. The commonly used approach of using phytic acid-element molar ratios as a bioavailability predictor may only be valid in limited circumstances due to various interference factors in legume matrices. Phytate degradation is emphasized as an important tool to enhance mineral bioavailability, and food processing strategies such as germination and fermentation are identified as promising methods to reduce phytate content and increase mineral bioavailability.

Summary: A physically crosslinked polyvinyl alcohol/phosphorylated chitosan (PPP) hydrogel electrode was designed using the freezing thawing method to improve the removal rate of uranium and reduce radioactive pollution. The PPP hydrogel showed excellent adsorption efficiency for uranium, with a treatment efficiency of 100% within 15 minutes for the absorption of 200 mL uranium tailings leachate. The PPP hydrogel exhibited good adaptability to a wide range of pH conditions and maintained an adsorption efficiency above 85% for a 950 mg/L uranium solution. The synergistic effect of various functional groups in the material, such as phosphate, hydroxyl, and ammonium, contributed to the adsorption capacity of PPP for uranium. Additionally, the electrochemical adsorption method significantly enhanced the adsorption performance of PPP hydrogel.

Summary: In this study, the coupling of dielectric barrier discharge (DBD) plasma and constructed wetlands (CWs) was found to be an efficient method for the simultaneous removal of dimethyl phthalate (DMP) and nitrogen. The coupling system achieved high removal rates of DMP and nitrogen, and the degradation processes and intermediate products were analyzed. The results showed that the coupling of DBD plasma and CWs can break the carbon-oxygen single bond of DMP and convert it into less toxic and less refractory compounds. This study provides valuable information for the treatment of wastewater containing toxic and non-biodegradable contaminants using the coupling of DBD plasma and CWs technology.

Summary: Electrochemical reduction of Cr(VI) to Cr(III) has been recognized as an effective method for treating toxic Cr(VI)-contaminated wastewater. In this study, we modified carbon-fiber felt (CFF) with a tree-like branched structure of polypyrrole (PPy) microwires and polyaniline (PANI) nanorods to enhance Cr(VI) reduction. The composite-modified CFF-PPy-PANI cathode showed significantly improved Cr(VI) removal and reduced energy consumption compared to other electrodes. The micro-nano PPy/PANI composite modification proved to be a promising strategy for efficient Cr(VI) reduction.

Summary: In this study, MoS2 nanoflowers-modified graphite felt (GF-MoS2) was used to construct an electrochemical apparatus (EA) and adsorption column (AC) for stable and effective removal of Cr(VI) at neutral pHs. The EA oxidized Cr(VI)-contaminated water first to generate H+ ions, and then reduced it using GF-MoS2 cathode, achieving high efficiency and stability. By assembling GF-MoS2-based AC, Cr(III) species in EA effluent were easily adsorbed, resulting in undetectable Cr species in AC effluent. The combination of GF-MoS2-based electrochemical reduction and adsorption is an effective approach for remediating Cr(VI)-contaminated water at neutral pHs.

Summary: In this study, three key factors affecting the planning of metro commercial passageways are selected and analyzed using the Pearson model, Logistic model and software simulation. Most studies on metro passageways focus on evacuation and transfer functions, with little research on metro commercial passageways. The purpose of this study is to improve the attractiveness of metro commercial passageways by improving the built environment, travel purposes of passenger flow and gate position. The analysis results show that passage length, escalator operation, distance from exit to bus stop, and passage width are highly correlated with passenger flow. Shopping trips are found to be the most significant purpose, and passageways closer to the gate location are more attractive to passengers.

Summary: The correlation between Fe loading and PAH production in Fe-loaded biochar was explored in this study. The results showed that increasing Fe loading in biochar reduces the PAH concentration, with the most significant decrease observed in naphthalene. This reduction can be attributed to various factors, such as a decrease in precursor compounds, substitution of C=O bond by Fe-O, and a decrease in dissolved organic matter concentration. However, the ecological toxicity of Fe-loaded biochar increases, posing a significant risk to human health. Therefore, considering the ecological risk of PAHs is crucial before the application of Fe-loaded biochar.

Summary: This study investigated the microbial removal mechanism of phosphorus (P) in an iron-based constructed wetland (CW) by constructing a CW with iron scrap. Efficient and stable P removal (97.09 +/- 1.90%) was achieved in the iron scrap-based CW, attributed to iron and P precipitation and improved microbially mediated P removal. Metagenomic analysis showed enhanced microbial diversity and enrichment of phosphate accumulating organisms in the iron scrap-based CW, explaining the higher P removal. Genes involved in P starvation, uptake, and transport were also enhanced in the iron scrap-based CW. Enrichment analysis demonstrated the up-regulation of the phosphotransferase pathway, indicating enhanced energy supply for microbial P removal. These findings provide a better understanding of the microbial removal mechanism of P in iron-based CW.
