Summary: In this study, the hydrolysis of magnesium hydride in MgCl2 aqueous solutions was systematically studied, showing linear dependencies of hydrolysis rate, pH, and yield on the logarithm of MgCl2 concentration. The precipitates formed do not contain chlorine ions and consist solely of Mg(OH)2, with crystallite size increasing with MgCl2 content. A pseudo-homogeneous model best described the hydrolysis kinetics, and the presence of Mg(OH)2 was found to partially suspend the reaction.

Summary: The study focused on preparing high-purity anhydrous magnesium chloride and analyzing its critical stages for purity. A mechanism for purity guarantee was proposed, and a new process for continuous production of magnesium metal was discussed. Incomplete chlorination reaction and hydrolysis were identified as key stages affecting purity, which could be addressed by controlling sample dimensions.

Summary: A study on the behavior of magnesium bis(trifluoromethanesulfonyl) imide solution in 1,2-dimethoxyethane revealed that at temperatures between 287 and 373 K, the solution exists as two immiscible phases with different properties. A temperature-molar fraction phase diagram was constructed, showing a closed-loop behavior. At 287 K and above, the solution separates into a concentrated lower phase and a dilute upper phase. As the temperature increases to 333 K, the lower phase becomes more concentrated and denser, while the upper phase shows opposite trends. From 333 K and above, the upper phase becomes more concentrated but its partial volume continues to grow, while the lower phase concentration decreases. At 373 K, the two phases merge into a single homogeneous phase.

Summary: Magnesium batteries offer advantages in terms of lower cost and better performance compared to lithium batteries, but they still face challenges such as the high charge density of magnesium ions limiting their intercalation in and out of the cathode, and strict requirements for magnesium ion coordination. This article provides an overview of key challenges and high-performance strategies, with a focus on cathode materials.

Summary: Glass powder samples of cordierite composition, doped with 8 mol% TiO2, were heat-treated to produce a series of Mg-bearing quartz solid solutions enriched in SiO2. Rietveld structural refinements showed that Mg-bearing Qss phases have trigonal symmetry and an intermediate structural arrangement dependent on composition. High-temperature diffraction measurements revealed a reversible inversion of quartz structure at SiO2-rich compositions, occurring at lower temperatures than pure quartz. Similarities and differences to Li-bearing Qss were discussed in the text.

Summary: The development of biodegradable electronics has eliminated the need for second surgeries for device removal, reduced infection risks, and opened up opportunities for zero-waste and green electronics. Magnesium-based biodegradable batteries have gained attention for their advantages such as high capacity, energy density, biodegradability, physiological tolerance, low cost, and high safety. However, controlling the degradation rate of the magnesium anode is crucial, and strategies such as coating and alloying elements are used. The development of biodegradable cathode materials and electrolytes is also important for fully biodegradable batteries.

Summary: The microstructure of Mg-Sn-Y alloys, including small grain size, uniform distribution of small second phase particles, and specific grain orientation, plays a crucial role in determining their discharge properties in Mg-air batteries. The presence of effective cathodes like Sn3Y5 and MgSnY phases promotes micro-galvanic corrosion, leading to the dissolution of the Mg matrix during discharge process.

Summary: This study investigates the decomposition mechanism of the Mg2+-anion ion pair on a model Mg metal electrode with trace H2O impurities. The results reveal that the introduction of H2O competitively solvating complexes induces the preferential decomposition of anions and reduces the cation transference number. The passivation of electrodeposits by MgO and Mg(OH)2 nanocrystals derived from parasitic reactions of anions and H2O molecules impairs the reversibility of Mg stripping/plating processes and the reproducibility of electrochemical experiments. The use of ternary electrolytes containing isobutylamine and trace di-N-butylmagnesium greatly improves the electrochemical performance.

Summary: The coexistence of single-crystallinity with a multidomain morphology is a paradoxical crystallographic phenomenon. The authors demonstrate the formation of metallo-organic single-crystals with a unique appearance, formed from unstable, monodomain crystals. Despite different morphologies and growth mechanisms, the crystallographic structures of mono- and multidomain crystals are nearly identical. Sonication of solvents generating radical species is essential for forming the multidomain single-crystals, offering opportunities to generate a new class of crystals.

Summary: Earth-abundant metals have become increasingly important in homogeneous catalysis, particularly in the hydroboration reactions of challenging substrates like nitriles, carbonates, and esters. The use of manganese(II) triflate salt in combination with potassium tert-butoxide and pinacolborane enables efficient hydroboration of these substrates with near quantitative yields in less than three hours at room temperature, showcasing a simple and effective methodology for these transformations. Further studies indicate that other earth-abundant metal triflate salts can also facilitate this reaction, expanding the scope of this catalytic process.

Summary: We demonstrate that the optical properties of indigo carmine can be controlled by encapsulating it within a coordination cage. Depending on the ratio of the host/guest molecules, the cage can selectively encapsulate one or two dye molecules. The 1:1 complex exhibits fluorescence, which is unique for an indigo dye in an aqueous solution. Furthermore, we have discovered that binding two dye molecules stabilizes a previously unknown conformation of the cage.

Summary: Metal-organic frameworks based on tetrahedral pyridyl ligands can form a series of isostructural crystals with different metal ions and properties. By conducting cation exchanges, an iterative crystal-to-crystal conversion can be achieved, which is influenced by the stability of the resulting coordination nodes. The optical and magnetic properties of the crystals are controlled by the metal cation, and the crystals preserve their morphology, enabling quantitative comparison of their properties at both the ensemble and single-crystal level.

Summary: Modulating the packing modes of bio-inspired supramolecular assemblies can significantly enhance the electromechanical properties of the assembly architectures. This study introduces a co-assembly strategy to achieve this by changing the amino acid chirality and mixing with a nonchiral bipyridine derivative. The resulting centrosymmetric-crystallizing coformer increases the single-crystal piezoelectric response of the electrically active bio-inspired molecular assembly.

Summary: In this study, the researchers engineered the precise positioning and alignment of arrays of two different guest molecules in a crystalline host matrix, resulting in new optically active materials. They found that sub-nm differences in the diameters of two types of 1D channels were enough for selective inclusion of dyes. Energy transport occurred between parallel-positioned nanochannels of different dyes through Forster resonance energy transfer (FRET). The color of individual micro-sized crystals depended on their relative position under polarized light, which was influenced by the crystallographic packing of the host matrix and the concentration of the dyes.

Summary: The symmetry of a crystal's morphology is usually related to the crystallographic packing's symmetry. Convex polyhedrons are commonly used to describe the morphology of single crystals. However, concave polyhedrons are indicative of twinning and polycrystallinity, and are not usually associated with single crystal structures. In this study, we report a new type of structure: a concave polyhedron shape single crystal with a multidomain appearance and a rare space group (P622). Despite its unusual structural features, the hexagonal symmetry is still evident at the morphological level.
