Summary: Bacteria can increase the Mg2+ content in biotic aragonite, but the molecular mechanisms and dolomitization of aragonite grains are still unclear. In this study, Bacillus licheniformis Y-1 induced biotic aragonite at different Mg/Ca molar ratios. The experiments showed that the Mg2+ ion content in aragonite increased with rising Mg/Ca ratios and the incorporation of Mg2+ ions was enhanced by specific biomolecules.

Summary: This study aims to explore the micro-influence mechanism of clay surface/interface property differences on coal slime flotation based on impurity defects. By using density functional theory (DFT) and flotation, the influence mechanism of Mg2+ doping on the microscopic interactions between particles of kaolinite and coal is preliminarily discussed. The results reveal the complex interaction between fine particles in coal slime and provide a theoretical basis for efficient selective separation.

Summary: In this study, the authors analyze the effect of Mg deficiency on the thermoelectric properties of the Mgx(Si, Sn) system. It is found that Mg deficiency induces point defects and phase separation, which alter the band structure. The measurements and calculations show that Mg deficiency leads to p-type behavior and a lower carrier concentration. Furthermore, Mg deficiency reduces the thermal conductivity and enhances the p-type thermoelectric performance of Mg silicides.

Summary: This study observed that introducing Mg2+ can enhance the stable yellow emission of Ag-13X zeolite and provided Ag-zeolite with a broad emission band and high photoluminescent quantum yield (PLQY) as a candidate material to replace traditional yellow-emitting phosphor. This work contributes as a valuable reference for the rational design of silver nanoclusters confined in zeolites and stimulates potential applications as novel phosphors.

Summary: Gadolinium-doped ceria (GDC) is an important fast oxygen ion conductor, where the distribution of O2--ions and vacancy defects in different cation environments is influenced by entropic effects. The study shows that the distribution of O2--vac pairs is practically independent of temperature, contrary to the traditional belief that energetic interactions dominate in solid oxide materials. The entropy effect not only affects the O2--vac pair distribution, but also influences the O2--ion hopping rate and barrier.

Summary: This study reports that octahedral hydrated Al3+ and Mg2+ ions act as kosmotropic ice makers of supercooled water (SCW) in electrolytic cells. Solutions of hydrated Al3+ and Mg2+ ions at concentrations of 10^-5 M trigger electro-freezing of SCW at -4°C near the cathode (-20 ±5 V). The efficiency of hydrated Al3+ ions is 100%, while Mg2+ ions induce icing with 40% efficiency. On the other hand, hydrated Na+ ions do not induce icing differently than pure water under the same experimental conditions. Molecular dynamics simulations show the formation of ice-like hexagons in the vicinity of Al3+ and Mg2+ ions, explaining their order-making properties during electro-freezing.

Summary: The paper discusses the sensitivity of Minidumbbell (MDB) structures to chemical environments and their potential in constructing DNA-based molecular switches, as well as the design of thermodynamically stable MDB structures with overhanging deoxyribonucleotides for functionalization. By utilizing 5-methylcytosine and adjusting the solution pH, MDBs with overhanging residues have been successfully obtained, leading to the creation of a pH and Mg2+-responsive molecular switch based on one of these new MDB sequences.

Summary: Salinity stress affects rice production globally and a salt-insensitive TILLING rice mutant, sitl1, was isolated using a forward genetics approach. The mutation in OsCZMT1 caused a reduction in Mg2+ and Na+ uptake, leading to salinity insensitivity. The OsCZMT1 protein possesses Mg2+ and Na+ transport activity and is mainly expressed in roots and leaves of seedlings, being highly upregulated in response to salinity stress.

Summary: An algorithm using Computer Vision (CV) and machine learning has been developed to calculate cloud parameters directly from Martian water-ice cloud properties. Testing on a previous data set showed promising results when the algorithm matched well with manual results under certain conditions, but performed less accurately in other conditions such as lighting changes, multiple cloud decks, or camera artifacts. Improvements are needed for the algorithm to more accurately measure cloud parameters under a variety of conditions.

Summary: Controlled formation of cocrystals of caffeine and 1-hydroxy-2-naphthoic acid was achieved at the interface between two immiscible electrolyte solutions under chemical polarisation, leading to the selective cocrystallisation as confirmed by X-ray diffraction and Raman spectroscopy. Positive interfacial potentials favored the formation of a specific polymorphic form of caffeine:1-hydroxy-2-naphthoic acid cocrystal. This electrochemically controlled cocrystallisation approach opens up new possibilities for drug development.

Summary: The dissolution behavior of clays in highly caustic environments was investigated using atomic force microscopy, and it was found that the dissolution behavior is similar in different solutions. The dissolution of the aluminate sheet in synthetic Bayer liquor is slower than that of the silicate sheet, and the steps on the kaolinite show a fast and slow dissolution direction.

Summary: This study reports on the effects of different N-donor ligands on the chemical composition and surface plasmon resonance (SPR) transition of copper nanoparticles (CuNPs) formed via laser ablation. Pyridines and alkylated tetrazoles showed minimal effects on the SPR transition, while the presence of tetrazoles resulted in a significant blue shift. This shift was attributed to the tetrazolate anions providing a reducing environment, preventing the formation of copper(II) oxides.

Summary: The study found that crystallisation in a non-aqueous solvent and in water resulted in different particle growth processes, with water showing aggregation related to single-crystal faces, while DMSO exhibited more random aggregation. Additionally, the solubility of barium sulfate was higher in DMSO compared to water, leading to lower nucleation rates in DMSO.
