Summary: In this work, the contrasting magnetic behavior of a bimorphic intermetallic compound TbPt3 is reported. The compound undergoes a structural phase transition and changes from a ferromagnetic state to an antiferromagnetic state. However, the antiferromagnetic state is unstable and can be induced to switch to a ferromagnetic state by applying a moderate magnetic field. Theoretical calculations suggest that the magnetic properties of the initial ferromagnetic state can be recovered by applying a magnetic field to the antiferromagnetic state. These findings provide an important opportunity to study the effect of crystal structure on the physical properties of TbPt3.

Summary: The study found that increasing pressure in the Sm-y(FexNi1-x)(4)Sb-12 system leads to changes in Sm content, increased microstrain, and decreased diffraction domain size. Beyond a certain threshold, the pressure promotes the formation of an additional phase, resulting in a reduction in power factor.

Summary: In this study, co-crystallisation is proposed as a strategy for materials discovery in the field of switchable spin crossover (SCO) systems. By synthesising 11 new cocrystals using different dipyridyl coformers, the authors demonstrate that the supramolecular architecture and spin crossover behavior of the cocrystals can be modified through changing the coformer. This presents a rapid, facile, and highly modular tool for the discovery of new switchable materials, and has the potential for wider applicability in the design of hybrid multifunctional materials.

Summary: In this study, accelerated aging reactions between two solid materials in the absence of solvent were utilized to synthesize spin-crossover-active coordination polymers and their Cu(II) analogues. The hygroscopicity of the ligands and the relative humidity of the reaction chamber were found to be crucial factors influencing the reaction rate. Deliquescence of the 4-aminotriazole ligand at high humidity and the diffusion of the ligand into the crystal of the metal salt during the reaction were observed. The formation of the product in the Cu analogue caused the deformation of the metal salt crystal and the formation of pseudocrystals with a fibrous structure.

Summary: The ability to use bio-inspired building blocks in the assembly of novel supramolecular frameworks is an exciting research field. In this study, the first polyproline helix that can self-assemble into a reversibly porous, crystalline supramolecular peptide framework (SPF) is presented. This framework is assembled from a short oligoproline, driven by hydrogen-bonding and dispersion interactions. Thermal activation, guest-induced dynamic porosity, and enantioselective guest inclusion have been demonstrated for this novel system. The principles of self-assembly associated with this SPF can be used as a blueprint for the further development of helical peptide linkers in the rational design of SPFs and metal-peptide frameworks.

Summary: To improve strategies for spin-crossover material design, obtaining isostructural materials is crucial for developing and understanding structure-property relationships. In this study, we synthesized four isostructural cocrystal solvates using a specific complex and coformer. The spin-crossover properties of these materials were determined by single-crystal X-ray diffraction and were found to be influenced by the hydrogen bond basicity of the anions and solvents present.

Summary: By integrating enantiomers into a conglomerate-forming matrix, we can control the formation of conglomerates. Ni(II) and Fe(II) form molecular alloys with Zn(II), with Ni(II) allowing for higher concentrations compared to Fe(II). Fast-growing precipitates are more likely to form chiral phases, while slow re-crystallizations favor racemic phases.

Summary: A new spin-crossover complex based on a heteroscorpionate ligand was synthesized and characterized. Thin films were grown on HOPG and Au(111) surfaces, and their properties were studied using X-ray absorption and X-ray photoemission spectroscopy. The results showed that the thermally induced spin-crossover is preserved at a sub-monolayer coverage on HOPG, while it is lost on Au(111) surface.

Summary: This study aims to explore the strategy of inducing chirality to achiral magnetic molecules for the preparation of magneto-chiral objects. The results showed that electrostatic or covalent surface grafting of the porphyrin molecules resulted in low induced circular dichroism (ICD), while incorporating the porphyrins into the interior of the double-walled helices yielded a moderate response. Drop-casting the porphyrin molecules onto the immobilized helices on a quartz plate resulted in a stronger and more variable ICD response. The patterns of aggregation and their influence on ICD and magnetic circular dichroism (MCD) were interpreted using electronic spectroscopy, electron microscopy, and IR spectroscopy. Except for the free base tetra-(4-sulfonatophenyl)porphyrin (TPPS), no enhancement of MCD was observed in the nanohelices, possibly due to spectral mismatch between the ICD and MCD peaks.

Summary: Antimicrobial resistance poses a significant threat to human health. In this study, we investigated the hydrogelation properties and antimicrobial efficacy of fluorescent supramolecular self-associating amphiphiles against both planktonic and biofilm forms of MRSA. The toxicity of these amphiphiles against the multicellular model organism Caenorhabditis elegans was also examined to assess their potential for real-world applications. Material characterization techniques, including optical density plate reader assays, rheometry, and widefield fluorescence microscopy, were used to determine the structure and sol dependence of hydrogel formation.

Summary: This study investigated the structures of two Se chains confined inside single-walled carbon nanotubes (SWCNTs), revealing that the chains were linear and parallel. The covalent bond between Se and SWCNT was found to be stronger than that between Se and trigonal Se (t-Se). The interaction between chains was attributed to the overlap of electronic orbitals, and the disappearance of this overlap in the encapsulated Se chains enhanced the covalent bonds.

Summary: In this study, we elucidate the hopping mechanism of hydrogen at intermediate temperature using a combination of experimental data and theoretical calculations. We find that the transition from thermal hopping to quantum tunneling is attributed to resonant tunneling, which is achieved through the resonant tunneling of discrete vibrational states between the edge octahedral site and the tetrahedral site. We also demonstrate that the tunneling rate can be tuned by energy level matching.
