Summary: Through the presence of STPP, the optimal colloidal structure with vaterite as the binding phase can be obtained, with a compressive strength of up to 16.99 MPa. The effect of STPP depends on its content, inhibiting the nucleation and growth of vaterite and calcite at low contents, and forming vaterite on the surface of bulk ACC through coupling mechanism at high contents.

Summary: This study reveals the relationship between the strontium partition coefficient and the calcite precipitation rate in synthetic calcite experiments, showing that this relationship varies systematically with the pH of the solution. It is hypothesized that this pH dependence is due to the involvement of HCO3- during calcite precipitation. By using an ion-by-ion calcite growth model, the hypothesis is successfully tested, explaining the pH dependence of the strontium partition coefficient and reproducing the observed relationships at different temperatures.

Summary: Due to the increasing scarcity of lithium resources, the recovery of lithium ions from water resources is an urgent problem. This paper proposes an environmentally friendly liquid-liquid extraction (LLE) process for lithium ion recovery. Nine hydrophobic deep eutectic solvents (HDESs) were formed using menthol (DLM) as a hydrogen bond acceptor (HBA) and octanoic acid, decanoic acid, and lauric acid (LA) as hydrogen bond donors (HBDs). HDESs synthesized with DLM and LA showed the best effect and were selected for the lithium extraction experiment. The single extraction efficiency of lithium ions was 80.69%, with optimized parameters such as rotational speed, equilibrium time, pH, molar ratio, and initial concentration.

Summary: The study demonstrates a certain stoichiometry dependence of calcium isotope fractionation during calcite precipitation, with a small magnitude of change observed across different supersaturation conditions. The results suggest that for most carbonate precipitating environments, solution supersaturation will play a stronger role in determining calcium isotope fractionation than stoichiometry.

Summary: The presence of bromine as a trace-element in calcium carbonate speleothems is a useful proxy for past volcanic activity. However, the chemical nature of bromine-containing impurities in speleothems is not well-understood, which hinders the interpretation of experimental measurements. A computer simulation study based on quantum mechanical calculations was conducted to investigate the incorporation of bromine in calcium carbonate polymorphs. The study discusses the distribution of bromate oxyanions and charge-compensating cations and predicts their stability and solubility limits.
