Summary: This paper investigates the weathering process of organic carbon (OCpetro) in black shale and reveals that small particles of OC are preserved during weathering due to their close association with mineral surfaces. In contrast, larger particles of OC are preferentially weathered. The findings highlight the importance of the texture of organic matter in controlling porosity generation and the weathering rate of OCpetro.

Summary: In this study, the effects of irrigating paddy fields with river water influenced by shale gas wastewater discharge were investigated. The irrigation did not cause the accumulation of trace metals in soil and rice grains, but led to an increase in chloride ions in the paddy soil. The use of influenced river water positively affected soil microbial diversity, but only after two years of irrigation. Therefore, the short-term effects of using river water affected by shale gas wastewater for agricultural irrigation are limited, but long-term effects should be seriously considered.

Summary: The study found that different pore sizes are affected differently by uniaxial stress, with mesopores around 100 nm being the most affected. Additionally, it was discovered that high pressure can increase the number density of large macropores, promoting gas migration and improving recovery rates. After pressure cycling, an irreversible rearrangement of pore size distribution takes place.

Summary: Soil aggregation and the translocation of clay and organic matter are important processes in mature soil, but they may also occur in the early stages of soil development. A time-lapse experimental study on early host rock weathering showed the formation of aggregates and clay translocation in response to irrigation with and without organic matter. The presence of organic matter influenced the dissolution capacity and surface morphology. Additionally, it affected the transport and formation of clay minerals and iron oxides. This study highlights the role of dissolution, neoformation, translocation, and aggregation in shaping soil structure evolution in carbonate host rocks during early pedogenesis.

Summary: The trace element chemistry of pyrite is important for understanding the formation of ore deposits, mineral exploration, and the evolution of Earth's chemistry. It is not clear whether trace elements are held within the pyrite structure or as nano-inclusions of other phases. This distinction is crucial as it affects the interpretation of trace element content.

Summary: The Upper Ordovician Wufeng Formation and Lower Silurian Longmaxi Formation black shales in the Sichuan Basin of South China are important targets for shale gas exploration. This study analyzed mineral composition, total organic carbon (TOC), and inorganic geochemistry to reconstruct sedimentary conditions and identify controlling factors of organic matter (OM) enrichment. The study found that high productivity and anoxic bottom water conditions are the main factors influencing OM accumulation in Wufeng-Longmaxi shales.

Summary: Time is often neglected in the assessment of erratic failure of shale rock. Constant stress induces time-dependent failure in brittle shale, mainly due to the formation of microcracks. Factors such as orientation of bedding planes and specimen heterogeneity also influence the nature of creep deformation in addition to time and constant differential stress levels.

Summary: Efficient carbon capture can be achieved using hybrid adsorbents comprising nanoporous substrates coated with imine polymers. The interactions between the CO2-adsorbing polymers and the substrates impact their capture capacity. Strong densification of imine polymers in mesoporous carbon and the formation of plugs at high loadings influence the accessible porosity and CO2 adsorption capacity. PEI in carbon shows highest capture capacity at low temperatures, making it suitable for temperature swing adsorption applications.

Summary: The adsorption behavior of water vapor in silica nanopores with different pore morphologies and surface hydrophilicities was studied. The study found that the adsorption isotherms are largely independent of pore size at low pressure, and the adsorbed amounts scale with the surface hydroxyl density. Patchy adsorbed layers were found in narrow pores, while a second adsorbed water layer was formed on larger pores and planar quartz surfaces. Molecular dynamics modeling revealed two preferential orientations for water molecules adsorbing to surface hydroxyl groups.

Summary: In this study, small-angle neutron scattering experiments were conducted on 71 samples from 13 different sets of mudrocks across the globe to capture the pore structure and develop fractal models to predict transport properties based on pore size distributions. The results show that transport phenomena in mudrocks are pore size-dependent, with different flow regimes developing in micropores, meso- and macropores based on hydrostatic pore pressures. The new model of pore size-dependent transport and integrated transport properties using fractal models provides a systematic approach to better understand fluid flow and transport phenomena in mudrocks on the reservoir and basin scale.

Summary: Interfacial reactions play important roles in elemental cycling on Earth and various human activities. Advances in techniques, such as ultrafast laser and X-ray sources, nanofabrication approaches, and computational chemistry, have enabled a more detailed understanding of mineral aqueous interfaces at atomic and nanometer scales. This critical review explores the progress made in the past 20 years and identifies challenges and future opportunities in understanding and predicting dynamic transient and reactive structures across greater spatial and temporal ranges, as well as systems of greater complexity.

Summary: This study presents a scalable and energy-efficient hollow fiber membrane contactor (HFMC)-based process for CO2 capture using a green solvent. The use of deep eutectic solvent (DES) in HFMC allows for effective interaction between DES and CO2, overcoming drawbacks of direct absorption in DES. The research evaluates the performance of commercial low-cost polymer hollow fiber membranes in CO2 capture with DES and provides insights into the CO2 separation mechanism.

Summary: The mantle source composition of the nascent oceanic crust in the central part of the Gulf of California has been investigated using basaltic glass samples. These samples show trace element patterns similar to enriched mid-ocean ridge basalts, suggesting that the nascent oceanic crust in the Guaymas Basin might be generated through partial melting of a depleted mantle source metasomatized by subducted slab materials.

Summary: Phosphorus is an essential element for life and its cycle in the ocean is closely connected with the carbon and oxygen cycles. The study of phosphate oxygen isotopes can provide insights into various reactions related to phosphorus. By analyzing carbonate fluorapatite samples from the Mesoproterozoic Era in North China, it was found that the oxygen isotope values were lower compared to modern samples, indicating a warmer climate during that time period and a potential reason for the scarcity of phosphorite.
