Summary: Four acceptor-donor-acceptor (A-D-A) type cyclopentadithiophene core-based non-fullerene small acceptor molecules were designed to improve the efficiency of photovoltaic cells. Density functional theory (DFT) and time-dependent self-consistent field (TDSCF) calculations were performed to analyze the optoelectronic properties and excited state calculations of the molecules. The designed molecules showed improved absorption, smaller band gap, and better charge transport probability compared to the reference molecule. The reorganization energy values were also lower in one of the molecules, indicating better charge mobility. The open-circuit voltage (V-OC) was calculated for the molecules in complex with a donor molecule.

Summary: This review discusses the successful application of cocrystallization in addressing the stability issues of active pharmaceutical ingredients (APIs) and the molecular mechanism behind it. By tailored design, delicate modification, and ingenious construction of cocrystals, the stability of APIs can be enhanced. A multidimensional structural understanding is necessary to manipulate interaction strength, molecular conformation, packing styles, and electronic effect. Prominent examples of cocrystals that have successfully dealt with stability problems are summarized, providing insights into vital structural factors in different scenarios and guiding future stable cocrystal design.

Summary: This article describes the synthesis and characterization of pure ZnO and Rb-doped ZnO nanoparticles using sol-gel technology. The samples were analyzed using X-ray diffraction, energy-dispersive X-ray spectroscopy, and field-emission scanning electron microscopy. The results showed that RbxZn1-xO NPs have a hexagonal wurtzite structure and their properties change with the Rb concentration. The particle size of the NPs decreased with increasing Rb concentration, and the compositions were in agreement with the selected elements.

Summary: The research aims to improve the mechanical strength of carbon-fiber composites for prosthetic feet by increasing the concentration and number of carbon fiber layers. The study found that increasing the number of carbon-fiber layers enhances tensile strength, while increasing the loading rate during tensile testing also leads to increased deformation rate. The experimental results indicate that these sample carbon-fiber composites can be used for the fabrication of prosthetic feet.

Summary: Metal-organic frameworks (MOFs) are multifunctional materials with varying framework architectures depending on the choice of metal ions and ligands. One important property is its luminescent behavior, which can arise from the ligand unit, metal ions, or cavity guest molecules. MOFs can be used to construct ratiometric fluorescence (RF) sensors by modifying the ligand unit and selecting suitable metal ions or guest molecules.

Summary: This article describes the new technical features and enhanced performance of the ID02 beamline with the Extremely Brilliant Source (EBS) at the ESRF. The beamline enables static and kinetic investigations of a broad range of systems in different size scales and time ranges. Additionally, it allows for multispeckle X-ray photon correlation spectroscopy measurements and relaxation of collimation conditions, resulting in higher flux throughput and lower background. The article highlights the importance of these developments in enabling structural, dynamic, and kinetic investigations of out-of-equilibrium soft matter and biophysical systems.

Summary: A new Schiff-base ligand and its metal complexes with Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) were synthesized and characterized. The metal complexes exhibited either a tetrahedral or octahedral structure. In addition to their antibacterial and antifungal efficacy, the metal complexes also showed higher antioxidant activity compared to the free ligand.

Summary: Producing chemical fuels from sunlight through photocatalytic CO2 reduction has many advantages, but most current photocatalytic systems can only absorb the UV-visible spectrum. Researchers constructed a Z-scheme In2S3-TiO2 system to utilize infrared light and create a high-temperature environment for photocatalytic reactions, achieving the utilization of the full solar light spectrum and improving CO2 reduction efficiency.

Summary: Magnesium alloys are widely used due to their high strength-to-weight ratio and superior mechanical properties. Alloying is an important way to enhance the strength of the metal matrix composite, but it also significantly affects the damping property of pure magnesium. The choice of alloying elements is crucial for improving the mechanical characteristics and resistance to corrosion of Mg-based materials.

Summary: Materials with high nonlinear optical (NLO) susceptibilities are considered as potential candidates for the next-generation NLO devices. Ferroelectric nematic (N-F) materials are argued to have the potential to become materials for the next-generation NLO devices. We conducted a study on a prototype N-F material and found a high nonlinear susceptibility in the transparent regime, which is one of the highest reported in ferroelectric liquid crystals. Despite the fact that the studied molecule was not specifically designed for NLO applications, it is concluded that there is still potential to obtain N-F materials with enhanced properties.

Summary: Designing an electronic structure and architecture with appropriate binding strength and abundant active sites is crucial for boosting the oxygen evolution reaction (OER). In this study, a hammer-shaped structure was developed by in situ assembly of ZIF-67 nanocubes on the surface of one-dimensional NiMoO4 nanorods. The resulting NiMoO4-ZIF hammers showed high activity towards OER after doping with a low amount of Ir, delivering a high current density with a low overpotential.
