Summary: This study investigates the impact of different occurrences of organic matter (OM) on hydrocarbon generation in mudstones. The results indicate that mineral-bound organic matter (MOM) is the most abundant form of OM and serves as the main hydrocarbon precursor in shallow formations. Soluble organic matter (SOM) contributes to hydrocarbon generation mainly at deep depths, while particulate organic matter (POM) shows consistent hydrocarbon contributions regardless of depth.

Summary: In this study, the efficiency of phosphorus (P) removal and enrichment in municipal wastewater by Biofilm Sequencing Batch Reactor (BSBR) was assessed. The role of polyphosphate-accumulating organisms (PAOs) and glycogen-accumulating organisms (GAOs) in P removal and the metabolic characteristics of dominant PAOs and GAOs at different influent P concentrations were studied. The findings revealed that BSBR provided sufficient reducing power and ATP for PAOs through different glycogen decomposition pathways, allowing for efficient P removal and enrichment.

Summary: During the Albian-lowermost Cenomanian, the northern margin in the Carpathian domain of the Western Tethys had deep basins filled with flysch and hemipelagic sediments. The terrestrial areas to the north of the Western Tethys experienced an increase in angiosperm diversity. Organic-rich sediments in the Silesian Basin contain both terrigenous and marine organic compounds, with an increase in accumulation intensity during the Albian-Cenomanian Boundary Interval.

Summary: We investigated the composition of organic phosphorus (Porg) in different soil organic matter (SOM) fractions using sequential chemical fractionation (SCF) procedure combined with nuclear magnetic resonance (NMR) spectroscopy. The SCF procedure extracted a higher amount of Porg compared to a single-step extraction. Approximately 38% of the extracted Porg was in the form of unresolved Porg pool, represented by broad signals in the phosphomonoester region of NMR spectra. The SCF revealed the recovery of phosphomonoesters in different SOM fractions, with a portion closely associated with the soil mineral phase. The extractability of inositol phosphates (IP) was also increased using the SCF procedure.

Summary: This study aims to provide researchers with all the necessary information about potential hydrocarbon-producing areas in Malaysia and the various lithologies connected to them by analyzing all earlier studies carried out in Malaysia. According to the data, the Bintulu, Pinangah, Begrih, Liang, and Tanjong formations have the highest potential to generate hydrocarbons in Malaysia, while the Kroh, Setap, Kalabakan, Temburong, and Belaga formations have the least potential. It is recommended that critical exploration activities be focused on the tertiary-aged formations, particularly those in East Malaysia, in order to increase Malaysia's hydrocarbon production.

Summary: This study investigates the adsorption mechanism of inorganic phosphate and organic phytate on nano-clay, revealing the impact of factors such as pH, ionic strength, and dissolved organic matter on the adsorption capacity. Findings show that laponite's adsorption capacity decreases with increasing pH, while the presence of dissolved organic matter inhibits phosphorus adsorption.

Summary: Tetrabromobisphenol A (TBBPA) is a new type of persistent organic pollutant that can cause environmental pollution and health problems, particularly when interacting with dissolved organic matter (DOM) which can enhance its acute toxicity to aquatic organisms, especially at higher DOM concentrations. Oxidative stress is identified as a characteristic mechanism of TBBPA toxicity to aquatic organisms in the presence of DOM.

Summary: This study investigates the influence of sulfur on the preservation of organic matter in various mudstones. The results suggest that sulfurization can efficiently preserve organic matter in certain environments, while the precipitation of iron sulfides competes with this preservation process.

Summary: The formation of sulfuric acid speleogenetic mineral deposits in the Pyramids plateau is linked to hydrocarbon gas seepages. The study reveals a hypogene sulfuric acid speleogenesis and presents a model explaining the different stages of formation from ascent of H2S gas to the development of gypsum fractures.

Summary: This geological and geochronological compilation database is specifically made to study a small Archean/Paleoproterozoic block located in the centre of the Precambrian rock exposition of Uruguay. The database includes petrographic and field outcrops data supporting zircons for textural analysis and U-Pb dating, as well as correlation of textures from different zircon samples. The data presented in the database are associated with a paper focusing on the extension and tectonic evolution of the Archean Pavas Block in Uruguay based on LA-ICP-MS U-Pb ages and airborne geophysics.

Summary: This geophysical study conducted in the Essaouira coastal area of Morocco outlined the spatial distribution of different geological formations and helped to determine the thickness and extension of the main aquifer for irrigation purposes. The study aimed to highlight the hydrogeological structures of the Essaouira Basin and identified significant geological layers near the Qsob River. It also found that the region is partially protected from marine intrusion due to its location between Tidzi Diapir and hidden diapir from Essaouira, with the electrical discontinuities abundant in the north Haha region.
