Summary: Hybrid devices based on spin-crossover/2D heterostructures provide a sensitive platform to detect spin transitions and tune the properties of 2D materials. However, the fragility of spin-crossover materials and the limitations of processing methods have restricted their applicability. This study presents an easily processable and robust hybrid device, where sublimable spin-crossover [Fe(Pyrz)(2)] molecules are deposited on chemical vapor deposition graphene. By growing an elusive polymorph of [Fe(Pyrz)(2)] on graphene, a fast and effective light-induced spin transition in the devices can be electrically detected.

Summary: A simple two-dimensional model of spin crossover materials leads to the emergence of spin-state smectic phases, which exhibit unique characteristics in terms of breaking rotational symmetry and translational symmetry in one direction only. These smectic phases result in plateaus in the fraction of high-spin metal centers and lines of Bragg peaks in x-ray and neutron scattering structure factors. The ordering of the smectic phases is unidirectional, with residual entropy scaling with the linear dimension of the system, contrasting with spin-state ices and antiferroelastic ordered phases.

Summary: In this study, a nitro-functionalised 1,2,4-triazole ligand was used to induce lattice distortion in a 2-D Hofmann framework material through competing supramolecular interactions. The crystallographic analyses revealed substantial deviations from a regular Hofmann structure, showing an array of ligand conformations and Fe-II coordination environments. Temperature-dependent magnetic susceptibility measurements showed a two-step spin crossover transition, providing insight into the competition between elastic interactions and crystallographically driven order.

Summary: This study investigates the behavior of the spin crossover compound [Fe(ptz)(6)](BF4)(2) in the host lattice of [Ru(ptz)(6)](BF4)(2), revealing a decoupling between crystallographic phase transitions and thermal spin transitions. Dilution with Ru reduces the cooperative character of the transition and results in observed hysteretic thermal transitions with slight domain formation. The transition temperature is slightly dependent on crystal properties, emphasizing the importance of Ru spatial distribution in addition to crystal shape and size.

Summary: Crystal packing energy calculations are used to analyze a family of spin crossover complexes, revealing a linear relationship between transition abruptness and changes in intermolecular interaction energy in the crystal structures. Abrupt transitions are associated with significant stabilising and destabilising changes in intermolecular interaction energies. Different classes of SCO complexes exhibit varying trends in relation to transition abruptness.

Summary: Inflammatory bowel diseases show gender bias, with female-specific differences influencing disease presentation and activity. Female genetic predisposition related to the X chromosome and hormonal fluctuations can affect gastrointestinal symptoms, pain perception, and pregnancy outcomes. Female patients with inflammatory bowel disease experience poorer quality of life, higher psychological distress, and reduced sexual activity compared to males. This narrative review aims to summarize the current knowledge of female-related features in clinical manifestations, development, therapy, and implications for sexual and psychological well-being. The goal is to provide gastroenterologists with guidance on female-specific differences to improve patient diagnosis, management, and treatment.

Summary: Celiac disease (CD) is an autoimmune disorder caused by gluten ingestion in genetically predisposed individuals. Besides gastrointestinal symptoms, CD can also lead to low bone mineral density and osteoporosis. The bone lesions in CD are influenced by various factors, and not only mineral and vitamin D malabsorption. This review aims to provide an updated overview on CD-induced osteoporosis and highlight new aspects such as the impact of the intestinal microbiome and sex-related differences on bone health, in order to improve its management.

Summary: In membrane-based water purification technology, the preparation conditions greatly affect the pore size distribution and dye removal efficiency of cellulose acetate membranes. Different fabrication methods and conditions, such as film casting speed, casted solution thickness, coagulation bath usage, and surfactant addition, significantly influence the membranes' pore size, porosity, and water permeability. The study also found that Azure A had better chemical affinity for cellulose acetate and was removed more efficiently, and both Azure A and Methyl Orange dye uptake followed a pseudo-second order model indicating chemisorption through valency forces.

Summary: A family of novel thermally activated delayed fluorescence (TADF) emitters was synthesized by a simple and metal-free method, and their structures were characterized. The photophysical and electrochemical properties of different donors were systematically tested and correlated with their performance in electrochemiluminescence using benzoyl peroxide as a co-reactant or in annihilation conditions. Efficiency in electrochemiluminescence was mainly determined by the electrochemical reversibility of the redox processes rather than the photophysical properties, and the annihilation efficiency strongly depended on the pulse sequence. The alkylated imidazole moiety allowed for the insertion of functional groups, enabling practical applications.

When paired with calcium tetrakis(hexafluoroisopropyloxy)borate Ca[B(hfip)(4)](2) electrolytes, PAQS showed cost-effective synthesis and environmentally friendly processing. By replacing the calcium metal anode with a calcium-tin (Ca-Sn) alloy anode, the cycling performance and rate capability of the PAQS cathodes were significantly improved.

Summary: Two new hexacoordinated Co(II)-based single-ion magnets were synthesized and characterized. The complexes exhibited metal-centered coordination with nitrate anions and a 2,6-bis(1H-benzimidazole-2-yl)pyridine ligand with n-octyl or n-dodecyl chains. The presence of long aliphatic chains allowed for their solubility in low polarity and volatile solvents, enabling the preparation of microstructural layers and patterns on relevant substrates using wet lithographic techniques. The complexes displayed positive axial D parameters and showed field-induced slow relaxation of magnetization.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
