Summary: Two studies were conducted to assess the use of recycled glass as a substrate for constructed wetlands and pharmaceutical removal in wastewater treatment facilities. The first study found that recycled glass performed similarly to traditional substrates for wetland-based wastewater treatment, with differences in pharmaceutical removal rates at different depths and treatment conditions. The second study showed that glass and sand had no significant differences in pharmaceutical removal, with some pharmaceuticals persisting over a retention time of 24 h.

Summary: This study investigated the sorption characteristics of natural manganese ore (NM) and its removal efficiency of ammonium and phosphorus from WWTP effluent in a simulated vertical flow NM constructed wetland (NM-VFCW). The results showed that NM could effectively sorb ammonium and phosphorus with a high removal efficiency, particularly for phosphorus. The manganese ore sand is highlighted as a powerful substrate for simultaneous advanced removal of phosphorus and ammonium in constructed wetland systems.

Summary: The study investigated the influence of membrane filtration on the removal efficiency of pharmaceuticals, finding a correlation between the hydrophilicity of the membrane and its effectiveness. The best separation efficiency was achieved for compounds with a molecular weight greater than 300 g/mol. A significant decrease in the separation efficiency was noted for low molecular weight molecules.

Summary: This study reports the synthesis, characterization, and application of amine-functionalized mesoporous nanocomposites based on natural rubber (NR) and wormhole-like mesostructured silica (WMS). The NR/WMS-NH2 composites were synthesized via co-condensation with 3-aminopropyltrimethoxysilane as the amine-functional group precursor. The NR/WMS-NH2 materials exhibited high specific surface area and total pore volume, and showed higher hydrophobicity and better adsorption capacity for clofibric acid compared to WMS-NH2.

Summary: Constructed wetlands show good removal performance for PPCPs through the combined processes of substrates, plants, and microorganisms. This review summarizes the direct and indirect roles of wetland plants in PPCP removal, with indirect effects appearing more significant. Wetland plants can enhance PPCP removal through improved rhizosphere microbial activities and the formation of supramolecular ensembles with humic acids, improving efficiency by up to four times.

Summary: This study explores the effects of admixtures on air lime mortars. The results show that air-entraining admixtures (AEA) can improve water vapour permeability and reduce water intake, while water-repellent admixtures (WRA) can increase mechanical strength but delay carbonation. The different admixtures have different implications on the short-term mechanical strength of mortars.

Summary: This study analyzes the archeobotanical materials recovered from the underwater archeological site of Gran Carro in central Italy to gain insight into the agricultural practices of the Iron Age settlement. The analysis includes the examination of cereal remains and the identification of preferred crops such as emmer wheat, barley, broomcorn millet, and foxtail millet. The findings provide evidence of millet consumption and suggest its cultivation may have been favored due to dry environmental conditions.

Summary: This study systematically investigates the pre-aggregation behavior of asphaltene in the absence and presence of ionic liquids (ILs) using molecular dynamics simulations. The effects of cation chain length and anion dimension on asphaltene aggregation are studied. The results show that ILs have a dispersing effect on asphaltene, and this effect is influenced by the alkyl side chain length of the cation and the radius of the anion. The findings are supported by DFT calculations. The study also demonstrates that CO2 acts as a precipitating agent, but does not affect the relative performance of the ILs.

Summary: Raman spectroscopy is widely used in the analysis of art objects due to its non-destructive nature and the availability of mobile instruments. However, the stable positioning required by Raman spectroscopy limits its accessibility to every spot of large artifacts. Therefore, exploring the use of zoom lenses for Raman investigation at different working distances is valuable.

Summary: This paper explores the use of portable Raman instruments to characterize natural dye lakes in paint mixtures, as an alternative approach to other Raman techniques. The study shows that the typical way of analyzing these materials through SERS or FT Raman spectroscopy is not always desirable in art analysis, thus, the potential of using commercial mobile instruments is explored. The results indicate that the two instruments provide significantly different information.

Summary: A mechanistic model was developed to assess the removal efficiency of pollutants in a wetland system, particularly in oil sands process-affected water (OSPW). The model simulated wetland mechanisms of chemical removal and showed that sustained wetland treatment is feasible. It is a helpful tool to evaluate the feasibility of treatment systems and to assess trade-offs in wetland design and operation.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
