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 study investigates the properties of 5 nm and 8 nm sized yellow inorganic pigment Bi4Zr3O12 prepared through the sol-gel auto-combustion technique. Annealing at 500 degrees C resulted in minor shifts in the 2θ position of Bragg peaks without structural phase change. Rietveld profile refinement and other analysis techniques confirmed the formation and crystallization of 8 nm Bi4Zr3O12 pigment. The pigment showed a micro-flower type morphology. The results also indicated the presence of oxygen vacancies and greater reflectance in the 8 nm pigment, making it suitable for optical devices and yellow pigment applications.

Summary: In this study, the deformation behavior of the plastic inorganic semiconductor Ag2S was investigated using in situ neutron diffraction at different temperatures. The results showed that at room temperature, the distribution of lattice strain among different crystallographic plane families may be responsible for the significant work-hardening behavior in bulk Ag2S. At 453 K, Ag2S undergoes a phase transformation from monoclinic to body-centered cubic phase, with a stress plateau and subsequent rehardening. The deformation mode of bulk Ag2S at the initial stage is likely due to the migration of silver ions, and as strain increases, it resembles the behavior at room temperature, leading to rehardening.

Summary: This study presents a silicon dielectric metamaterial (SDM) composed of two outer symmetric semi-circular rings and two inner symmetric split-ring resonators (SRRs). The electromagnetic responses of the SDM device in different modes were studied through numerical simulations and experiments. Increasing the structure height of the SDM device resulted in red-shifted resonances and stronger intensities. This study provides a new design strategy for the development of frequency filtering, polarization switching, and resonance modulation characteristics in THz-wave applications.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. 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.
