Summary: Prolonged increase in atmospheric CO2 concentrations has resulted in global warming. Geological CO2 storage (GCS) in sedimentary reservoirs is a promising solution to alleviate this issue, and CO2 mineral trapping is the only mechanism that guarantees permanent and safe storage. This review provides an overview of GCS as a solution for mitigating global warming, emphasizing the importance of CO2 mineral trapping for permanent and safe storage and discussing the mechanisms and factors influencing its kinetics.

Summary: This research introduces a novel hybrid system, the Minimal Liquid Discharge (MLD) process, to capture the value of seawater reverse osmosis brines. The MLD process consists of several units, including nanofiltration, Mg reactive crystallizer, multi-effect distillation, and NaCl thermal crystallizer. The system not only provides significant economic benefits, but also produces high purity minerals and salts.

Summary: This study focused on using BMED technology to produce high-concentration NaOH solutions from post-carbonation brine for improved efficiency in mineral carbonation. By adjusting the solution volume ratios, proton leakage through the anionic exchange membrane could be effectively utilized to extract NaOH from brine with high Mg content.

Summary: Fluorite can host significant quantities of trivalent rare earth elements by substitution with divalent calcium, making it an ideal phosphor material. Investigations on fluorite ores in central India revealed multiple traps formed by different methods. The naturally occurring fluorites have sufficient quantities to cater to industrial demand.

Summary: The debate on the 'resource curse' has been ongoing for decades with no consensus due to diverse findings from empirical literature. This study evaluates the determinants of gold production in Zimbabwe from 1980 to 2018, showing that international gold price is negatively related to gold production in the country due to the greater impact of domestic economic conditions. Policies to liberalize gold trading, promote political stability, and strengthen institutions are recommended to stimulate gold production in Zimbabwe.

Summary: Nanofiltration (NF) plays an increasingly important role in Zero Liquid Discharge (ZLD)/Minimal Liquid Discharge (MLD) systems, improving the efficiency of downstream technologies for recovering valuable minerals from seawater and brines. However, the purity of the recovered minerals often does not meet market specifications, making ZLD/MLD economically unfeasible. In this study, a novel positively charged NF membrane was developed using NH2-MIL-101(Al) and ZnO nanoparticles in a chitosan matrix to enhance magnesium and calcium selectivity.

Summary: The bacterium that causes syphilis, Treponema pallidum subsp. pallidum, has been successfully cultured in vitro for over 3 years using a system of coculture with Sf1Ep rabbit epithelial cells in TpCM-2 medium and a low-oxygen environment. Specific requirements for sustained growth and multiplication, such as the presence of Sf1Ep cells and certain basal media, have been identified.

Summary: This paper evaluates the geochemical interactions posed by the injection of hydrogen into porous media. The results show that dissolution of carbonates, anhydrate, and halite can occur over time, leading to precipitation of calcite, formation of H2S, and long-term closure of the pore structure due to scale formation. The study also suggests that the reduction of pyrite to pyrrhotite is likely to occur at temperatures above 90 degrees C, enhancing H2S formation. These findings contribute to a better understanding and selection of geological porous media for large-scale hydrogen storage.

Summary: This article investigates the effect of sandstone clay concentration on CO2-water-sandstone interactions through simulations of CO2 injection in two different clay-content sandstones. The results show that high clay-content sandstone has a higher CO2 mineral-trapping capacity and an increased porosity after a 400-year storage period.

Summary: Using MoO3 as catalyst and NaNO3 as nitronium source, aromatic precursors were nitrated in a planetary ball mill. Reaction times and nitrate/precursor molar ratios varied in the experiments. Nitration was observed with maximum yields approaching 80%. Product ratios of para to ortho isomers were consistently above 1, indicating reaction on the catalyst surface. Byproducts, including oxidation products and double nitration products, were observed. The product yield approached its theoretical maximum when the aromatic precursor was the limiting reactant; the yields remained well below their expected maxima when the limiting reactant was nitrate. Factors affecting the reaction rate include the aromatic activation, basicity, enthalpy of vaporization, reaction enthalpies and viscosity.

Summary: The study explored the surface-free energies on carbonate surfaces in contact with different aqueous solutions and crude oil, focusing on parameters such as interfacial tension (IFT), contact angle, works of cohesion (WC) and adhesion (WA), and spreading coefficient (SC). MgSO4 showed the greatest IFT reduction, MgCl2 and KCl had the shortest and longest adsorption times, respectively. Na2SO4 was able to change wettability from strongly oil-wet to strongly water-wet, while other salts could alter contact angle.

Summary: The study reveals the conditions governing carbon mineral trapping and its quantification for a range of rock compositions in intraformational baffles. It shows that the presence of baffles with certain rock properties can enhance or reduce carbon mineral trapping capacity, depending on clay and carbonate mineral content. Furthermore, analysis indicates that the precipitation of secondary carbonates occurs at the interface of the two rock types.

Summary: This study investigated the structural, optical, and thermoluminescence properties of TlGaS2 single crystals, revealing their potential applications in 2D structures. The crystal exhibited a monoclinic unit cell structure with distinct peaks in the XRD pattern, while the band gap and Urbach energies were determined to be 2.57 and 0.25 eV, respectively. Thermoluminescence measurements showed a TL peak with a maximum temperature of 573 K, indicating the presence of a deep trapping level with an activation energy of around 0.92 eV. Additionally, the TL peak temperature was found to shift towards higher temperatures with increasing heating rates.
