Summary: This study investigates the self-sealing capability of different caprocks and identifies the key minerals that trigger self-sealing. The results show that carbonates and clays are the key minerals for self-sealing. The CO2-fluid-rock interactions in carbonate-rich shale are violent and fluctuate greatly, which is not conducive to short-term safe sequestration but favorable for medium to long-term safe sequestration.

Summary: Solubility trapping of carbon dioxide (CO2) in deep saline aquifers is an effective mechanism for carbon storage. This study investigates the scaling relations of convective mixing in the dissolution of CO2 in aquifer brine. The results provide new insights into the factors affecting the dissolution flux and onset time of convection, which are important for the prioritization and selection of appropriate aquifers for geological CO2 storage.

Summary: Compressed CO2 energy storage is a reliable solution for physical energy storage. The main challenge is achieving high-density storage of low-pressure CO2. In this study, a new adsorption transcritical compressed CO2 energy storage system was proposed, using adsorbents for low-pressure, high-density storage. The results showed that the storage density of the adsorption gas storage system was 43.46 kg/m3, 24.8 times higher than the density of CO2. Heating the adsorbents to above 160 degrees Celsius can further increase the storage density.

Summary: This study numerically explores the mechanisms of geological factors in controlling the heat mining process by CO2 injection. The findings show that heat extraction using CO2 as working fluid can achieve a high mining rate, but the CO2 plume exhibits severe segregation effect. Increasing the horizontal correlation length and mean permeability can effectively promote the mining rate, while increasing permeability heterogeneity and anisotropy can cause a reversed trend of mining rate variation.

Summary: This paper conducted experimental studies on the percolation, permeability, and adsorption of supercritical CO2 in coal seams, and analyzed the effects of injection pressure and temperature. The results showed that the permeability of supercritical CO2 in coal increased by 93% compared to CO2. The excess adsorption capacity of supercritical CO2 by coal decreased with increased pressure, and the adsorption capacity decreased by 8.3% on average with a temperature increase of 10 degrees C. The propagation velocity of the longitudinal wave in the sample decreased significantly after the action of supercritical CO2, indicating its effective promotion of pore and fracture development in coal.

Summary: The study investigated the effect of thermal fracturing due to rapid quenching on the permeability and wave velocities of caprock and reservoir samples at the In Salah CO2 storage site in Algeria. The results showed that the thermal shock fracturing effects from CO2 injection in the Krechba field were negligible, indicating that the conclusions may be applicable to global Carbon Capture and Storage prospects.

Summary: Miscible CO2 flooding is an effective method for oil recovery, but the heterogeneity at the pore level can significantly affect its efficiency. This study proposes a method based on NMR T-2 spectrum to determine the distribution of residual oil in sandstone without the need for additional agents. The results show that the residual oil is mainly distributed in small pore throats, and the heterogeneity of pore size affects the displacement efficiency. There are also unswept areas with residual oil that can be targeted for further improvement.

Summary: CO2 uptake by smectites can cause swelling and self-stressing in shallow clay-rich caprocks under CO2 storage P-T and constrained conditions. However, little data exist to constrain the magnitude of the effects of CO2-H2O-smectite interactions on the sealing properties of clay-rich caprocks and faults. Our experiments on Opalinus Claystone (OPA) cores and simulated fault gouge showed that the permeability of clayey caprock can decrease significantly when exposed to CO2-rich fluid, depending on the initial water activity in the clay material. These findings have important implications for assessing the self-sealing potential of fractured and faulted clay-rich caprocks.

Summary: Cobalt is a crucial transition metal with unique physical properties needed for high-tech applications, but its recovery efficiency is generally low due to the variability of cobalt ores. Understanding the geometallurgical properties of cobalt ores, such as ore mineralogy, is important in developing extraction processes. Further research is needed for sustainable cobalt sourcing and processing.

Summary: This study investigates the geomechanical properties of organic-rich, calcareous shales buried to 100-180 degrees C, finding that the elastic stiffness increases with thermal maturity due to intense carbonate cementation. A multiscale model accurately predicts stiffness at micro and core scales, showing a negative correlation between creep modulus and clay/kerogen content.

Summary: Sulfidic mine tailings, waste materials from mining and mineral processing, can contain high levels of sulfur and metal(loid)s even after bioleaching. A study found that one-part alkali-activated slag mortars are a promising solution for recycling sulfidic mine tailings due to their practicality, easy transportation, and user-friendly production. Incorporating up to 50 wt% mine tailings into these mortars resulted in the formation of C-(N)-AS-H gels and had a significant impact on their physical and chemical properties.

Summary: This study presents a new micromechanical model for simulating calcareous mudstones and predicting their macroscopic elastic response. The results show that the contribution of calcite to the overall anisotropy of mudstones is significant, and a micromechanical model is successfully calibrated using high-load nanoindentation tests. Furthermore, the applicability of the model to other calcareous mudstones is demonstrated using core-scale data.

Summary: Scandium (Sc) is a dispersed metal in Earth's lithosphere and is considered a critical metal due to its paramount significance in scientific research and technical innovation. However, its production is significantly hindered by the scarcity of economically viable grades and the market price of Sc oxide is astonishingly high. This review examines the relationships between Sc deposits and specific magmatic, supergene, and hydrothermal processes, as well as discussing the Sc enrichment mechanism and associated tectonics. The resources in the Bayan Obo deposit are discussed in detail as an illustrative example.

Summary: Black mass refers to mechanically processed end-of-life lithium-ion batteries used for recycling valuable metals such as cobalt, lithium, manganese, nickel, and copper. The complexity of the feed material poses a significant challenge in effective processing. Analytical methods such as automated SEM-EDS, micro X-CT imaging, and micro-XRF were used to characterize the phases and particle chemistry of black mass samples from a European source. The integration of these analytical methods allows for detailed phase characterization and potential guidance for recycling routes and chemical assaying.

Summary: The Fulmar Formation sandstones from the Fulmar Field in the Central North Sea have a burial depth of 3.2 km and a temperature of 128 degrees C. However, their quartz cement content is only 3.7 +/- 1.7% (1 sigma), which is significantly lower than predicted by temperature-related quartz precipitation kinetics models. Oxygen isotope microanalysis of quartz overgrowths indicates limited cementation at temperatures above 110 degrees C. The low volumes of quartz cement can be explained by the effective stress history of the Fulmar Formation, which experienced a decrease in pore fluid pressures and an increase in effective stress due to lateral seal failure.
