Summary: The study indicates a conditional correlation between shale oil production and groundwater produced water constituents in the most productive area of the Permian Basin, showing that expanding from conventional wells to unconventional wells has led to dramatic increases in total dissolved solids, chloride, sodium, and calcium levels in groundwater. Additionally, the total dissolved solids, chloride, and sodium levels in PW samples are positively correlated with nearby oil well density.

Summary: This study compares and evaluates the environmental and social impacts of primary and secondary sources of rare earth elements (REEs) production. The results show that production from secondary sources has lower environmental impact. Important impact categories related to particulate matter formation, abiotic resource depletion, and fossil fuel depletion could be mitigated by avoiding tailings disposal. Therefore, increasing the recycling of secondary REE sources is encouraged to balance demand and resource exploitation.

Summary: There are significant differences in the chemical components, mineral elements, and rare earth elements of Huangguanyin oolong tea from different production regions. The Huangguanyin tea from YX has higher contents of thearubigin, tea polyphenols, and water extract, while the Huangguanyin tea from WY has higher contents of glutamic acid, gamma-aminobutyric acid, beta-aminobutyric acid, and other components. The classification models based on chemical components and elements achieved high discrimination rates, indicating the feasibility of classifying Huangguanyin oolong tea by production regions.

Summary: Bioleaching, using microorganisms to dissolve minerals and extract Rare Earth Elements (REEs) in aqueous media, has gained attention for its potential eco-friendliness compared to other extraction methods. Mixed culture bioleaching is preferred for efficient REEs extraction, promoting closed-loop recycling and reducing supply chain issues. This literature review provides an overview of challenges, opportunities, microorganisms, mechanisms, approaches, parameters, and techno-economic considerations related to REEs bioleaching, and offers recommendations for future advancements.

Summary: In this study, the impact of fish-farm activities on trace elements in the coastal waters off Jeju Island, Korea was investigated. The concentrations of trace elements were higher in the coastal waters and correlated with NH4+. Excess dissolved trace elements in the coastal waters were mainly produced inside fish farms, along with NH4+ and light-REEs. Although some dissolved trace elements were scavenged onto particles in fish-farm rearing waters, these particles would be eventually discharged into the coastal ocean and release the trace elements back into the water columns.

Summary: This study reports enhanced flux in plasticization-resistive ultra-robust membranes by thermally cross-linking a blend of carboxylated polyimide (PI) and ladder-like amino-polysilsesquioxane (LAPSQ). The increase in gas permeability is influenced by the Durene moiety and the cross-linking process. The cross-linked membrane shows larger cavities, increased hardness and reduced modulus.

Summary: ZIF-8 membranes have potential for separating propylene/propane gas mixtures, but non-selective defects limit their performance. Atomic layer deposition of zinc oxide on the ZIF-8 membrane surface can improve performance by minimizing defects. After ZnO ALD treatment, the propylene/propane separation factor of ZIF-8 membranes increased, but propylene permeance decreased.

Summary: Per- and polyfluoroalkyl substances (PFAS) are a class of emerging compounds that cause global health and environmental problems. In this study, a modified polar organic chemical integrative sampler (POCIS) was used to assess the uptake of PFAS from sediments and water. The results showed that the uptake of PFAS from water and sediment can be explained by sampling rate models and mass transport based on external resistance from the sediment layer. The study also observed faster uptake of PFOS compared to PFOA and higher uptake in tanks with combusted soil. Overall, the external mass transport model provided a mechanism to extend the POCIS design for measuring porewater concentrations and sampling releases from sediments.

Summary: One of the most significant problems faced by hydraulic engineers is the local scouring of in-stream structures. Fractional factorial methods have been used to optimize the design of scour protection methods with fewer experiments and high accuracy. This study investigated the effects of three factors (spur dike angle, riprap size, and riprap extent) on local scouring using Taguchi and grey relational analysis (GRA) methods. The results showed that riprap aprons can reduce scouring depth and move the scouring hole away from the structure.
