Summary: Hydrogen, as a clean energy source and alternative to fossil fuels, has the potential to significantly reduce carbon emissions. However, the transportation and storage of hydrogen pose significant challenges for realizing a hydrogen economy. Ammonia, with its high hydrogen content and easy liquefaction, is considered a promising hydrogen carrier. The traditional method of ammonia production, the thermocatalytic Haber-Bosch process, requires high temperature and pressure, limiting its production to centralized systems. Mechanochemical ammonia synthesis offers an alternative method under near ambient conditions, connecting with localized sustainable energy systems. This perspective introduces the state-of-the-art mechanochemical ammonia synthesis processes and discusses the challenges and opportunities it presents for a hydrogen economy.

Summary: In this study, a new phase of Na3InCl6 with higher conductivity than the previously reported phase was prepared using a mechanochemical method. A Zr-substituted system of Na3-xIn1-xZrxCl6 with solid solutions based on Na3InCl6 was also prepared. The introduction of Na vacancies had a positive effect on Na-ion conduction, and the ionic conductivity increased with an increase in the number of Na vacancies.

Summary: Photochemical reactions in reactors are limited by the penetration depth of light and require high dilutions. This study presents a method of UV photochemistry in a ball mill without bulk solvents. Triphenylene was synthesized with yields of 81% and 92% using the Mallory reaction and cyclodehydrochlorination (CDHC) respectively. The method was successfully scaled up to gram scale and demonstrated robustness for different substrates. Mechanosynthesis was also used to assemble nanographenes, providing a new tool for precise construction.

Summary: Inspired by guanine motifs, the G-quadruplex-forming ability of a guanine-based Y2 molecule containing bithiophene and peripheral dodecyl chain units in the presence of different cation salts was investigated. The structural characterization revealed that the radius and nature of the coordinating cations crucially affected the structural characteristics and ion migration ability of G-quadruplexes.

Summary: Thirteen new crystal structures of cyclic NH carboximides have been determined and compared based on their intermolecular hydrogen bonding patterns. The structures include a new cyclobutane-fused succinimide, seven new simple bi- and tricyclic succinimides derived from Diels-Alder reactions, three methylated glutarimides, a morpholinedione and adipimide, and the first seven-membered ring NH carboximide to be characterized. The compounds were found to adopt ribbon structures, centrosymmetric dimers, and bonding between NH and a remote bridging ether oxygen. Halogen bonding was also observed in one case.

Summary: The synthesis, structure, magnetic properties, and magnetic structure of two molecular chiral magnets and one inorganic chiral magnet are discussed. The chiral non-collinear spin structure is achieved through the Dzyaloshinsky-Moriya interactions, and the transition from CHM structure to CSL structure is observed experimentally. The chiral magnetic structures are found to be topologically protected and exhibit extremely stability due to the lack of defects affecting them.

Summary: In this study, stable and porous rare-earth metal-organic frameworks (RE-MOFs) were constructed using redox-active tetrathiafulvalene tetrabenzoate as the linker. The single-molecule magnets (SMMs) displayed slow relaxation and the property was modulated by oxidation and reduction reactions. The results highlight the advantage of MOFs in constructing redox-switchable SMMs.

Summary: An attempt to create asymmetric core-shell hybrid structures using Preyssler polyoxometalate (POM) as an anion template resulted in an unprecedented example of asymmetrical coverage on a symmetrical Preyssler P5W30 core. The incomplete coverage of the Ag shell on the core allowed both components to have exposed surfaces, leading to successful dual functionalization of the POM and silver cluster hybrid.

Summary: In this study, three heteronuclear Ir-III-Co-II arrays have been synthesized, where compounds 2 and 3 are discrete ionic complexes and compound 4 consists of a self-assembled two-dimensional coordination polymer. The Co-II cores in all arrays exhibit octahedral geometries with varying degrees of distortion. Additionally, these arrays show slow magnetic relaxation and solid-state phosphorescence, with compound 4 exhibiting severely quenched phosphorescence due to strong connections between the Co center and the metalloligand.

Summary: In this study, an attempt at creating asymmetric core-shell hybrid structures using Preyssler polyoxometalate (POM) as an anion template and [Ag((BuC)-Bu-t C)](n) as the shell resulted in successful dual functionalization of the POM and silver cluster hybrid. The asymmetric Ag-43 shell on the P5W30 core showed exposed surfaces, allowing for typical redox peaks to be detected in cyclic voltammetry. This unprecedented example demonstrates the challenges and success of achieving asymmetrical coverage on a symmetrical Preyssler P5W30 structure.
