Gulf Sturgeon (Acipenser oxyrinchus desotoi) in the Mobile Bay Estuary, Alabama: Documentation of use outside of designated critical habitat. Journal of Coastal Research, 39(6), 1021–1043. Charlotte (North Carolina), ISSN *** Sturgeon (GS) are an anadromous, federally threatened subspecies of Atlantic Sturgeon that feed primarily in estuarine and marine systems in the northern Gulf of Mexico from October to April. All extant natal river systems and adjacent estuarine and marine environments were designated as critical habitat for GS in 2003, excluding the Mobile River Watershed because of lack of data indicating an extant spawning population at the time of listing. Previous studies had identified that GS from river systems east of Mobile Bay use habitats within the Mississippi Sound, suggesting GS must at least traverse Alabama waters. Therefore, this study's objective was to quantify the use of the Mobile Bay Estuary by GS. GS were acoustically tagged in all extant natal river systems and detected by an array of receivers deployed in the Mobile Bay Estuary during 2016–21. A total of 210 adult and subadult GS from western (n = 97) and eastern (n = 113) river systems were detected in the Mobile Bay Estuary for up to 4 months, with 110 individuals detected from 2 to 6 years during the monitoring period. The sustained use of the Mobile Bay Estuary by GS from western and eastern river systems strongly indicates that Alabama's waters are suitable habitat despite extirpation of the natal spawning population in the Mobile River Estuary. Foraging in the Mobile Bay Estuary is probable because previous sediment and benthic macroinvertebrate sampling in this system indicated relatively low-percent sand content and high polychaete richness, which are characteristic of foraging habitats previously identified in the Pascago

3D-printing is an emerging method for manufacturing polyamide (PA) reserve osmosis (RO) membranes for water treatment and desalination, which can precisely control membrane structural properties, such as thickness, roughness, and resolution. However, the synthesis-structure (i.e., degree of cross-linking (DC), m-phenylenediamine/trimesoyl chloride (MPD/TMC) ratio, and membrane thickness) to property (permeability and water-salt selectivity) relationships for these membranes has not been well understood. At the same time, a microscopic understanding of the physical mechanism of water and salt transport is needed to guide the design of high-performance 3D-printed membranes and improve printing efficiency. Thus, the atomic-scale transport features and energetics of water and salt ions are studied at high pressure for the 3D-printed PA RO membranes with the different DCs and MPD/TMC ratios through non-equilibrium molecular dynamics (NEMD) simulations. Factoring in membrane structure properties, rejection ratio of salt ions and pressure-dependent water flux, 3D-printed PA membranes having an MPD/TMC ratio of 3.0:2.0 and a DC between 80%~90% attains ideal performance: high water flux, high rejection of salt ions, and excellent structural integrity. Mechanistically, water permeability for highly cross-linked PA RO membranes depends on the temporary on-and-off channels that allow water molecules to jump from one cavity to another at high pressure. In addition, higher pressures cause a rapid compaction of PA membranes’ free volume and membrane thickness. Membrane failure at high pressure is determined by the DC and MPD/TMC ratios-dependent compressive yield strength. In short, these findings provide physical insights for optimizing existing PA membranes and designing next-generation desalination membranes at the molecular level. © 2022, The Authors.

Chemical additives to perovskite precursors constitute a predominant route to passivate defects in perovskite films and improve carrier charge dynamics. In this work, ionic liquids (ILs) with chloride and iodide anions are used as additives for bulk passivation of perovskite films. The ionic liquids in the form of 1‑butyl‑4-methylpyradinium iodide (IL-I) and 1-ethylimidazolium chloride (IL-Cl) are mixed individually with a precursor of Cesium Formamidinium Lead Triiodide and Methylammonium Chloride (CsFAPbI3−MACl). The decay of charge carriers within the perovskite film before and after passivation with ILs was measured by Time Resolved Photoluminescence Spectroscopy (TRPL). The effect of added ILs on the recombination rate of the photocarriers was investigated by analyzing the decay of the TRPL signal in all samples. The average lifetimes obtained within one day of preparations were 79 ns, 73 ns and 275 ns for pristine perovskite, IL-I passivated perovskite and IL-Cl passivated perovskite films, respectively. These values show that the presence of the IL with chloride anion greatly improves the average lifetime of the charge carrier by around 250%, while IL with iodide anion decreased the lifetime by 32% as compared with the pristine perovskite sample. This finding renders the IL-Cl passivated perovskite films as a valuable resource in applications ranging from photoelectric to hydrogen generation devices. © 2023

The prevalence of per- and polyfluoroalkyl substances (PFAS) in ground and surface water poses serious threats to public health. However, an effective destructive technology for PFAS remains elusive. Herein, we report the results of perfluorooctanoic acid (PFOA) degradation by a high temperature transformed, photocatalytic titanium-based metal-organic framework (MOF), MIL-177-HT, with infinite one-dimensional (1D) channels. MIL-177-HT removed 83% of PFOA within 24 hours with a 32% photo-induced defluorination rate. While the crystallinity and porosity were retained after photocatalysis, pore size distribution was altered after light irradiation due to PFAS adsorption and partial degradation. The results demonstrated the potential of a phase-transformable MOF for efficient PFAS removal but more importantly, the study revealed the key challenges for more effective use of photocatalytic MOF for PFAS removal: increasing the accessible adsorption sites of MOF for PFAS and improving its stability in neutral and alkaline water. © 2023, The Authors.

The mandatory carbon reduction guidelines and regulations in Indonesia encourage all industrial sectors particularly the petroleum industry to implement decarbonization programs by systematically reducing carbon emissions as part of climate action. Unlike existing carbon emission studies in the petroleum industry, the literature lacks studies on the decarbonization patterns. In addition, the effectiveness of carbon mitigation in the upstream oil and gas field has not been studied so far. This study developed short panel data models to understand the current decarbonization efforts and patterns during 2015–2018. The results indicate that the considered variables are significantly impactful in carbon reduction with different coefficient patterns. It is suggested to associate decarbonization with oil and gas production and highlight energy efficiency optimization to stabilize production. The impact of financial, human, and administrative resources on the supporting facility is critical for executing sustainable carbon mitigation projects. © 2024 The Authors

The government determines forests based on the main functions of: Conservation forest, protection forest and production forest. The Petungkriyono protected forest is one of the conservation areas located in the Petungkriyono, Pekalongan City. Conservation of protected forests in Petungkriyono is very much needed considering the development of the wider city, so that the forests that were originally forest areas that functioned as green open spaces have been greatly reduced, especially in areas along the river that leads to Pekalongan City. The research method used in this study is to use descriptive research methods. The data collection technique used is the study of literature. Data analysis techniques were performed using a Likert scale calculated by discriminant analysis. Type of participation contributed by the community in the protected forest area of Petungkriyono;a) participation of ideas, b) energy, c) property, d) skill e) social participation.

Glyphosate, the most used herbicide in the world, poses a serious threat to terrestrial and aquatic ecosystems. Magnetic nanosorbents composed of magnetite (Fe 3 O 4 ) cores coated with humic acid were synthesized, characterized, and used to investigate the removal of glyphosate (GLY) through adsorption. The spherical-type particles (average particle size = 9 nm), highly crystalline spinel structure of the iron core and surface morphology were unchanged before and after GLY adsorption. Adsorption fits with the pseudo second-order kinetic and Langmuir isotherm models. The humic acid coated magnetic nanomaterials (HA-MNP) exhibit a high maximum adsorption capacity for GLY, 30.4 mg g −1 . The result of thermodynamics study indicated the adsorption is endothermic and spontaneous. Removal efficiency increased with decreasing solution pH. Chloride ions exhibit no inhibition, while nitrate and phosphate compete with GLY adsorption to HA-MNP. Although multi-parameter models have been successfully applied to model adsorption processes, such studies often require large sets of experiments and complex mathematical representations to capture the interactive play of different variables. We observed excellent agreement between predicted and experimental results using a new approach employing dimensional analyses with the application of Buckingham’s π theorem for the combined concentration and dosing effects in the removal of GLY. In addition, error functions (r 2 =0.88) confirm the applicability of this model in the batch scale design independently of the sorbent dose and initial concentration. The accurate demonstration of this modeling approach for the adsorption of GLY on HA-MNP illustrates promise for predicting and optimizing adsorption treatment processes for different sorbents and target pollutants. © 2022, The Authors.

Water pollution stemming from non-metal contaminants, notably fluorine, poses a grave health risk. The prevalent organic fluoride called pentafluoropropionic acid (PFPA), necessitates efficient remediation. Employing photocatalysis, this study strives to synthesize titanium dioxide (TiO₂) via microwave assisted sol-gel technique, integrating a natural-resource-based zeolite carrier to synthesize photocatalyst/zeolite nanocomposite for the removal of fluorinated compounds from water by degradation of PFPA. Minitab-17 facilitates data analysis, with the reaction surface (RS) method optimizing parameters: 0.5 g dosage, UV irradiation, and alkaline conditions. The RS model predicts a 60.2 % removal efficiency, closely aligning with the observed 58.7 % removal. Energy efficiency is pursued through microwave hydrothermal synthesis, while secondary aluminium slag and waste glass contribute to zeolite synthesis, promoting waste reduction and recycling in harmony with circular economy principles. © 2024
