Summary: A series of single-phase nickel-substituted magnesium spinel ferrites were synthesized using the hydrothermal technique, and their morphology, structure, magnetism, and electrochemical properties were investigated. Experimental characterization techniques confirmed the presence of a single-phase spinel structure, with a decrease in lattice parameter and clustering of nanoparticles as nickel concentration increased. Raman and FTIR spectra indicated changes in wave numbers and the shortening of Fe-O bonds. Additionally, the ferrites exhibited increased saturation magnetization, decreased coercivity, decreased specific capacitance, and increased loop size. These ferrites are promising for energy storage applications.

Summary: This article describes the effects of mechanical treatment on the surface morphology of cemented carbide substrates and the microstructure and properties of chemical vapor deposited (CVD) Ti(C,N) coatings. The relationships between substrate surface roughness and the grain size, preferred orientation of crystallites, residual stress, indentation hardness, and coating adhesion are discussed. The results show that surfaces with microscopic steps and edges facilitate the growth of large Ti(C,N) grains with a weak {211} texture, while coatings deposited on smooth substrates have finer grains, a pronounced {211} texture, and better adhesion. The indentation hardness of the coatings is not affected by substrate treatment. The physical background of these relationships is explained.

Summary: This study reports on a method to achieve programmable humidity-responsive actuating behaviors by introducing photoprogrammable hygroscopic patterns into shape memory polymers. The researchers found that by treating the polymer surface to form an Fe3+-carboxylate coordinating network, transient hygroscopic gradients can be generated under UV light, driving the deformation of the polymer. Furthermore, the shape memory effect can be effectively used to adjust the direction and amplitude of the moisture-driven actuating behavior.

Summary: Bi2WO6 with double active sites of tunable metallic Bi and oxygen vacancies (OV-Bi/Bi2WO6) was prepared by solvothermal treatment and used as an efficient photocatalyst for the partial oxidation of cyclohexane (CHA) to cyclohexanone (CHA-one) in air. The Bi : Bi2WO6 ratio in OV-Bi/Bi2WO6 could be tailored by controlling the solvothermal temperature, and the synergistic effect between DMF and EG increased the reduction of MDF/EG and promoted the production of Bi. OV-Bi/Bi2WO6 showed significantly enhanced photocatalytic activity attributed to its specific surface area, photo-absorption, oxygen vacancies, and efficient electron-hole separation.

Summary: A simplified treatment process is reported to convert 2D poly(ethylene oxide)/sodium alginate/tannic acid thin films into 3D-shaped moisture- and NIR light-responsive actuators. Wetting the film surface releases residual stress in a gradient manner, driving the wetted regions to bend bidirectionally. A gradient cross-linking network formed by Fe3+ ions and sodium alginate chains stabilizes the resulting 3D shape and provides moisture-responsive morphing behaviors. Fe3+ ions also enable the film to respond to NIR light by self-assembling with tannic acid molecules. Films with versatile 3D shapes and deformation modes can be conveniently fabricated using this one-step treatment process.

Summary: Designing and synthesizing highly active single atom catalysts, especially monodispersed noble-metal atoms fixed in two-dimensional layered double hydroxide (LDH) nanostructures, is crucial for accelerating the slow oxygen evolution reaction (OER). In this study, Ru single atoms (SAs) were stabilized on NiFe LDH (SARu/NiFe LDH) via an oxygen-coordinated bond after a facile solution reduction procedure. The SARu/NiFe LDH exhibits higher activity than pure NiFe LDH in basic media, with 99.3% Faradaic efficiency based on rotating ring-disk electrode measurement. This study provides a general avenue for developing efficiently monoatomic and even multiatomic catalysts in the future.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
