Summary: X-ray imaging of strains has made impressive progress recently, with improved resolution and optical elements. Development of new detectors has revolutionized measurement strategies. The introduction of a new accelerator ring concept has significantly increased brightness and coherent flux. In the next decade, fast three-dimensional imaging methods will emerge to track the evolution of strains in materials.

Summary: In this study, a simple strategy was demonstrated for constructing low-tortuosity through-pores in both vertical and planar directions of electrodes by casting large particles into single-particle-layer electrodes. Through multi-scale characterizations and simulations, correlations between material/electrode structures, electrolyte permeability, polysulfide migration, and sulfur reactions were elucidated. The high-loading and dense sulfur cathode fabricated by this method delivers a high specific capacity at a very low electrolyte/sulfur ratio.

Summary: In this study, copper sulfide nanostructures were successfully synthesized via the hydrothermal method, with the impact of different pH values on crystal structure investigated. The results showed a decreasing trend in copper sulfide crystalline size with increasing pH values. Additionally, flower-like nanostructures formed at lower pH values, supporting an inverse relationship between crystallinity and pH value.

Summary: In-situ synchrotron X-ray diffraction was used to study K0.5Bi0.5TiO3-BiFeO3-PbTiO3 ceramics with a Curie temperature around 450 degrees C. The study revealed a self-adapting mechanism in tuning intergranular stress through partial phase switching, which enhanced domain switching behavior in both tetragonal and rhombohedral phases. This mechanism could be exploited in other perovskite systems for high performance high temperature piezoelectric ceramics.

Summary: We investigated the effects of Cu doping on the structure, morphology, magnetic properties, cytotoxicity, and biocompatibility of ZnO nanostructures. Our results show that the incorporation of Cu2+ ions inhibits the growth of nanorods and leads to the disappearance of nanorod morphology at higher doping levels. X-ray photoelectron spectroscopy confirms that Cu ions substitute Zn2+ sites in their divalent state. Magnetic measurements reveal a significant change in the magnetic features due to doping. Cytotoxicity assessment demonstrates that Cu-doped ZnO samples are non-toxic. Our findings suggest the potential usefulness of Cu doping in spintronic/magnetic media devices and as a promising approach for new functional biomaterials in biomedical applications.

Summary: The measured lattice-plane spacing of silicon 28 is important for counting Si-28 atoms to realize the kilogram. It is assumed that the measured lattice spacing represents the unstrained crystal forming the analyser. However, studies suggest that the measured value might refer to the surface of the analyser. To confirm these findings and support experimental investigations, a comprehensive analytical model is provided for a triple-Laue interferometer with a bent crystal.

Summary: A series of acrylic phenyl benzoate polymers with high molecular weight were synthesized and characterized using a novel polymerization method. Characterization methods included polarized optical microscopy, differential scanning calorimetry, and wide-angle X-ray scattering. All polymers exhibited liquid crystal phases, with some showing nematic phases and others showing smectic phases depending on the chain length. The transition from monolayer to bilayer smectic phase was observed when polymerizing a monomer with a terminal chain length of five carbon atoms.

Summary: The effects of acidic treatment on the photovoltaic properties of dye-sensitized solar cells were investigated. TiO2 nanostructure was prepared using a chemical bath deposition method and modified with various acidic treatments. The results showed that acidic treatments significantly affected the structure, morphology, optical properties, electrochemical properties, and photovoltaic properties. XRD analysis confirmed the formation of TiO2 nanostructure electrodes. After acidic surface treatment, the photoconversion efficiency increased from 1.97% to 3.23%, electron lifetime increased, and charge transfer resistance decreased.

Summary: In this study, Carbon Aerogel (CA) with varying pore size and surface area was synthesized by adjusting the ratio of Resorcinol (R) and novel Catalyst (triethyl amine [TEA]) (C). The CA with R/C = 1000 exhibited the highest CO2 uptake capacity at 40 atm CO2 pressure, while the activated version of optimum CA (R/C = 1000) showed one of the highest CO2 storage capacities reported so far. This research proposes highly efficient and tunable CAs for enhanced CO2 storage.

Summary: Alloys-based materials have evolved from conventional alloys to multi-principal elements, giving rise to the emergence of high entropy alloys. These alloys have unique properties that can be tailored based on specific requirements, making them suitable for applications in catalysis, energy storage, and other fields. Recent research has also highlighted the excellent magnetic properties of high entropy alloys, with the ability to tune these properties through the manipulation of alloying elements. This review article provides an overview of the features, synthesis methods, and magnetic properties of high entropy alloys, as well as discussing the magnetic properties of high entropy oxides.

Summary: In this study, a modified solid-state synthesis technique was optimized to synthesize a single spinel phase for a novel (CuNiTiZnFe)3O4 High Entropy Oxide (HEO), and its magnetic behavior was investigated. Pure spinel HEO was synthesized using different synthesis approaches. The synthesized HESO exhibited typical ferrimagnetic properties and had a high magnetization and coercivity compared to other HEOs. XPS analysis revealed the ionic states of different cations present in the (CuNiTiZnFe)3O4 HESO.

Summary: In this study, two-dimensional carbon nanosheets derived from biomass precursor were successfully synthesized through a cost-effective salt-templated process. The thickness and capacitance of the nanosheets were altered by adjusting the carbon precursor to salt-template ratio. Thinner carbon nanosheets exhibited superior electrochemical properties and capacitance compared to thicker ones, without the need for chemical activation.
